    <p>MEMS mirror device is a device that reflects and scans a laser by the torsion of the beam structure. By miniaturization of the device, the reduction of the deflection angle of the mirror becomes to be an issue. In this research, we fabricated a MEMS mirror structure using film metallic glass formed by sputtering as a new material for the beam structure. In order to avoid the deterioration of the cross-sectional shape of the structure caused by the film thickening, a reverse lift-off method was used in the fabrication process. It is the method that forms film on a desired pattern and remove the others to obtain the flat and uniform thickness structure. Several conditions of the anneal was tested and the structure annealed at 200 ℃ shows less deflection than others. The fabricated structure was driven by external excitation, and it was confirmed that the resonance frequency was almost as designed.</p>

    <p>Microvalves are used in microfluidic systems such as micro reactors, and micro-total analysis systems (μ-TAS). Most microvalves need electrical wiring on each one, and the need prevents further integration and miniaturization of the microfluidic systems. Hence, we suggest new microvalves remotely controlled without the wiring on each valve. The proposed microvalves are driven by heat from magnetic nanoparticles in an alternating magnetic field. The proposed microvalves consist of thermo-responsive gels and the magnetic nanoparticles with a diameter of 20 nm or less. The nano-scale magnetic particles with superparamagnetic behavior generate heat in an alternating magnetic field. The aim of this study is to verify possibility of the new microvalves. First, Fe<sub>3</sub>O<sub>4</sub> magnetic nanoparticles were synthesized and characterized with an X-ray diffractometer, a transmission electron microscope, and a magnetic property measurement system. Then, the heat generation of the synthesized magnetic nanoparticles was measured in an alternating magnetic field. From the measurement, the possibility of the proposed microvalves was verified calculating how long it require to shrink the thermo-responsive gels by heat generated from the magnetic nanoparticles.</p>

    <p>In this study, we propose a combinatorial evaluation method for evaluating the corrosion resistance of the Ti-Ni-based high formable shape memory alloys (HFSMAs) based on anodic polarization tests. The proposed evaluation substrates compose nine samples which have different compositions. These samples are deposited on a glass substrate by carousel sputtering system and microelectromechanical processes. Further, we performed anodic polarization tests on the Ti–Ni–Zr and Ti–Ni–Cu HFSMAs samples. The polarization curves are obtained by sweeping the potential and the current density at the passive state (<i>i</i><sub>ps</sub>) of each composition tested is compared. In case of the Ti–Ni–Zr alloy, <i>i</i><sub>ps</sub> varied depending on the Zr content. When the Zr content ranged from 10 to 15 at.%, their <i>i</i><sub>ps</sub> were comparable with that of Ti<sub>48</sub>Ni<sub>52</sub> used in medical devices. On the other hand, in case of the Ti-Ni-Cu alloy, their <i>i</i><sub>ps</sub> were similar to that of Ti<sub>48</sub>Ni<sub>52</sub> regardless of Cu content. We obtained Ti–Ni–Zr and Ti–Ni–Cu HFSMAs having a corrosion resistance equivalent to that of Ti<sub>48</sub>Ni<sub>52</sub>. Furthermore, we conducted XPS analysis to investigate the passive film of HFSMAs. The thin surface film of Ti-Ni-Zr alloys were composed of TiO<sub>2</sub> and ZrO<sub>2</sub>, while that of Ti-Ni-Cu alloys were composed of only TiO<sub>2</sub>. We have concluded that the formation of TiO<sub>2</sub> enriched protective thin surface film might have been responsible for the high corrosion resistance.</p>

    <p>In recent years, minimally invasive treatment has attracted attention, and catheter surgery is one of them. On the other hand, in catheter surgery, visual information is limited to only a two-dimensional image by an X-ray camera. Therefore, there is a problem that stress is applied to the blood vessel wall and it is damaged, so doctors are required the skill of catheter surgery. In order to improve the surgeon's surgical technique, the authors have proposed a surgical simulator that realizes real-time visualization of stress by the photoelastic method. In this study, we propose a measurement system using a photoelastic method that can visualize stress in three dimensions and examine the blood vessel model shape applicable to the proposed measurement system.</p>

    <p>In this paper, we fabricated two types of optical textured glass substrates by a polydimethylsiloxane (PDMS) nanoimprint lithography (NIL) on the front glass to enhance conversion efficiency of dye-sensitized solar cells (DSSCs). Two types of master molds for nano-texture (N-Tx) and micro-nano-double texture (D-Tx) were prepared by an aluminum anodic oxidation. Both N-Tx and D-Tx showed higher total transmittance and lower reflectance than bare glass. Finally, we fabricated DSSCs with textured glass. The used dye was red N719. The cell size was 6 mm square. As the results, the conversion efficiency of DSSCs with textured glasses increased by 26% for N-Tx (<i>η</i> of 3.67%) and 19% for D-Tx (<i>η</i> of 3.47%) compared to DSSC with flat glass (<i>η</i> of 2.91%).</p>

    <p>Further miniaturization of the diaphragm for capacitive pressure sensor requires thinner structures to deform micro diaphragm sufficiently by small differential pressure. Since stiffness of thinner structures decrease, the influence of internal stress introduced during processing cannot be ignored. In this paper, we proposed methods of controlling the internal stress for micro diaphragm using thin film metallic glasses (TFMGs). We fabricated micro diaphragms using Ru67Zr25Al8 [at.%] TFMGs. The TFMGs were fabricated by a r.f. sputtering system, and then as sputtered TFMGs had compressive internal stress. Subsequently, the as-sputtered TFMGs on Si substrate were annealed at 315-440°C for 5 minutes in vacuum. After annealing, micro diaphragms were fabricated by etching Si substrate using a reactive ion etching system. Although annealing temperatures were lower than glass transition temperature, initial internal stress was relaxed partially by the structural relaxation of the TFMGs during annealing process. While the tensile thermal stress was induced during cooling process at the interface between the substrate and TFMG. Although micro diaphragm was not induced thermal stress at interface between the substrate and TFMG, the tensile stress applied to diaphragm in the radial direction at the edge. When annealing temperatures were between 320°C and 340°C, the internal stress changed from compressive to tensile. A flat diaphragm was obtained when annealed at 330°C or higher. The pressure sensor modeled by diaphragm annealed at 340°C and the virtual electrode plate showed a linearity of 6.48 [%F.S.]. By proposed method, we succeeded the flat diaphragm and showed the method of tension control of the diaphragm.</p>

    <p>A diaphragm structure is a fundamental structure in a micro machine such as MEMS. Conventionally, Si has used as a diaphragm material. However, in recent years, in order to make the diaphragm structure more sophisticated and miniaturized, high sensitivity difficult to realize by using Si is required. Therefore, in this study, we aim to create a highly precise diaphragm structure by using the thin film metallic glass which is an amorphous alloy shown glass transition as a new material which meets these demands. Pd<sub>77</sub>Cu<sub>6</sub>Si<sub>17</sub> (at. %) and Ru<sub>65</sub>Zr<sub>30</sub>Al<sub>5</sub> (at. %) are used for thin film metallic glass. The thin film metallic glasses are deposited on the Si substrates by sputtering. Internal stress of each film is controlled by adjusting Ar pressure during sputtering and annealing after sputtering. The internal stress of the Pd<sub>77</sub>Cu<sub>6</sub>Si<sub>17</sub> (at. %) thin film is always tensile stress and it is minimum at an Ar pressure of 0.5 Pa, and its value is 23.6 MPa. Under this condition, we can create a highly precise diaphragm. On the contrary, the internal stress of Ru<sub>65</sub>Zr<sub>30</sub>Al<sub>5</sub> (at. %) thin film is always compressive stress in the range of sputtering Ar pressure. So, we try to relax the internal stress of Ru<sub>65</sub>Zr<sub>30</sub>Al<sub>5</sub> (at. %) thin film by annealing. In the proper annealing conditions, a diaphragm having the same flatness level as Pd<sub>77</sub>Cu<sub>6</sub>Si<sub>17</sub> (at. %) is realized.</p>

    化学修飾を多孔体に施すことで濡れ性が大きく制御できることに着目し,溶液プロセスによる多孔体の内部まで親水化する手法を構築するとともに,これまで確立されていないナノスケールでの濡れ性・熱伝達性能を評価できる手法を新たに構築する。次に構築した手法を用いて化学修飾キャピラリーの濡れ特性制御メカニズムを実験的に明らかにすることで,化学的濡れ性が蒸発熱伝達に与える影響を明らかにする。さらに,多孔体への浸透圧効果を直接観察し,熱輸送機構への効果を実験的に検証することで,多孔体界面での蒸発熱伝達の理論限界を超える新たな熱輸送メカニズムの創出を目指す。
