A micro focusing Small Angle Neutron Scattering (mf-SANS) instrument is planned for compact accelerator based neutron source project to analyze the internal structure of material in 1-100 nm scale. As the key component, the ellipsoidal neutron mirror strongly affects the focusing performance of mf-SANS instrument. To fabricate the neutron mirror, this paper presents a new manufacturing process chain by following the steps of fast milling and precision cutting of aluminium, electroless nickel plating, ultra-precision cutting by diamond tools, super-smooth polishing and super mirror coating to generate the mirror with high form accuracy and good surface roughness time-efficiently. As a preliminary test of the proposed process chain, a workpiece with flat surface made of electroless nickel plating on aluminium is adopted and machined by ultra-precision cutting and polishing. The surface roughness is reduced to under 1 rms. According to the experiment results of reflectometry, the neutron beam can be totally reflected with high intensity and little scattering.

The purpose of this research is to develop patient movement support system based on image processing. Although there are many types of fall preventive movement sensor using in the hospital, these sensor have problems that are malfunction alert, alert after the accident. This report refers to the evaluation of basic system that continuously monitors the patient movement based on depth sensor.

Zr based metallic glass thin films can be a promising structural material for MEMS. We have tried to deposit ZrCuNiAl thin films by means of rf magnetron sputtering using an alloy target and investigated their mechanical properties. Morphological change of thin films with deposition conditions is found to affect their hardness, Young's modulus and tensile strength. Detailed investigation of the effect of deposition conditions on the glass transition behavior is underway. We are also going to study an ability for micro-fabrication above its glass transition temperature.

Flux and energy of ions impinging onto growing film surface in sputtering process can be controlled by electro-magnetic coil around magnetron and substrate bias voltage. High ion flux and energy were effective to increase the c-BN fraction in deposited films. Substrate material was also found to be very important factor for depositing c-BN films. It was confirmed that the growth of c-BN films on cemented carbide substrate needs higher substrate bias voltage than on Si wafer.

Low-temperature amorphous silicon (a-Si) and microcrystalline silicon (uc-Si) are promising materials for use in large-area electronic devices. In this study, we have been developing a low-temperature and high-rate Si deposition technology using very high-frequency (VHF) plasma excited under atmospheric pressure (AP). In this presentation, we discuss the influences of plasma parameters, such as input VHF power density, H2/SiH4 ratio and gas residence time in the plasma, on the crystallinity and property of the deposited Si films. In addition, the characteristics of bottom-gate thin film transistors (TFTs), the channel layers of which were prepared using AP-VHF plasma, will be presented.

Monitoring the wear life of the tribological amorphous carbon (a-C) film through luminescent spectroscopy is proposed. The monitoring can be achieved by detecting the degree of luminescence from the layer that is located under a-C film. Hence, the structure of the coating consists of substrate/luminescent sensing layer/a-C layer. In this study, fabrication and characterisation of such coating structure are presented. Firstly, the coating structure, in which the luminescent sensing layer is ZnS:Mn thin films, was fabricated. The thin films were deposited by R.F. magnetron sputtering in argon plasma and post-annealing at 700°C. Subsequently, a-C films were deposited onto the luminescent layer by R.F. magnetron sputtering. The structures of the coatings as well as luminescent properties were analysed. However, due to the requirement of high temperature annealing to enhance the luminescent properties of ZnS:Mn thin film, silica coatings containing CdSe/ZnS quantum dot powder prepared from polysilazane precursor solution were also fabricated for another candidate for luminescent layer. The process is found to be simpler and requires significantly lower temperature annealing process.

We have been exploring a Ni-free material showing stable self-propagating reaction for medical use. In this work, we focused on the Ti-Si multilayer films. In order to study the effect of composition of the multilayer films on the reaction, we prepared the multilayer films with various thickness ratios of constitution layers. Ti-Si multilayer films of Ti:Si = 5:4 showed very intensive self-propagating reaction and its critical thickness which is the smallest thickness to induce self-propagating reaction was thinner than Al-Ni multilayer films. This suggests that the Ti-Si multilayer films can be a better nano-heating material than Al-Ni multilayer.

In this paper we discuss the etching effects of electrolyzed oxidizing water (EO water) on the surface of Permalloy 45. We threw light on the etching efficiency of NaCl EO water and Na2SO4 EO water on the surface of Permalloy 45 by comparing it with the etching efficiency of soaking in HCl solution and H2SO4 solution. The comparative study showed that as for the etching efficiency on Permalloy 45, NaCl EO water and Na2SO4 EO water was superior to HCl solution and H2SO4 solution. Also, EO water can process an etching equally to each composition elements of Permaooly 45 compared with chemicals.
