We have tried to apply the deoxidization/oxidization reaction using electron and hole provided by irradiating ultraviolet ray on photocatalyst and fluorescent for machining the materials. When the cup-type nickel tube was polished using these phenomena, the following results were obtained; the more rich of photocatalyst promoted mechanical polishing, the more rich of fluorescent substance promoted chemical polishing, the harder pad easily polished the workpiece, no ultraviolet-ray irradiation did not promote the reaction, and the pH-value of slurry decreased through polishing time.

Ultrasonic vibration assisted machining appeals to researchers because of the improvement in surface quality and/or machining efficiency owing to reduced machining forces and heat from friction in machining process of hard-brittle materials. The concept was applied to chemo-mechanical grinding of fused silica glass in our experiments in anticipation of enhancement of surface roughness and/or material removal rate. The related experiments were performed on an in-house built apparatus. The preliminary results indicate that the newly proposed combination of chemo-mechanical grinding and ultrasonic vibration is feasible to precisely manufacture fused silica glass. The material removal rate is increased while the surface roughness remains the level similar to that in chemo-mechanical grinding without vibration. Compared to conventional loose abrasive polishing with aqueous slurry consisting of ceria, the material removal rate is considerably augmented. Certain processing parameters were experimented so as to find out their effects on material removal rate and surface roughness phenomenologically. The probable mechanism of material removal in ultrasonic vibration chemo-mechanical grinding was also explored as well as conventional chemo-mechanical grinding. A synergic mechanism of chemical reaction and mechanical removal is implied from the experimental results, which results in the removal of material from fused silica glass surface.

This report deals with the machining performance of rock samples in vacuum with a rock-crasher embedded in the science integrated package for future lunar exploration. A tool bit with pyramids driven with a solenoid was made from tungsten carbide. The generative impact force was 150 N at a driving frequency of 50 Hz device. The machining amount in vacuum was smaller than that in air because debris adhered on the tool by electrostatics. The tool temperature rose 4°C while the solenoid temperature rose 48°C.

In an ultrasonically forced insertion(USFI) process, to clarify the mechanism of reduction of press–fit force, frictional force, frictional stress and displacement on the contact surface of a metal rod and a metal plate were simulated by a large deformation analysis using a finite element method (ANSYS Inc.). Under the conditions of the start and limit of a USFI process, axial displacement and radial displacement on the contact surface were simulated. As the result, the reduction of frictional stress, and the contact and separation between the rod and plate with a hole expansion were confirmed.

This report deals with a rock-crasher embedded in the science integrated package for future lunar exploration. The crusher measures 59×60×129 mm and weighs 490 g. The generative impact force and consumption power were 150 N and 6 W at a voltage of 24 Vp-p and a driving frequency of 50 Hz device. A tool bit with pyramids driven with a solenoid was made from tungsten carbide. When a basalt sample was randomly fed with a feedscrew and crank mechanism in two directions, a smoothed surface was obtained. Ridges remained in one direction feeding even by skewing the tool at an angle of 11.4°.

To reduce the electric power consumption is strong demand in these years. This study focused on to the electric power consumption of feed drive systems for NC machine tools. In order to clarify the factors which influence the power consumption, electric power consumptions of an NC machine tool are measured under various cutting and rapid feed motions. It is also measured under difference servo gains and time constant parameters of NC servo controls in acceleration-deceleration motions.

We have tried to fabricate the BN films containing cubic phase using rf magnetron sputtering. In this work, we have mainly studied the effect of substrate temperature and bias voltage on the growth of c-BN films. FT-IR measurements revealed that the films of almost c-BN single phase can be grown when a substrate temperature is 600C and a negative bias voltage higher than 100V is applied. It is considered that both high substrate temperature and ion bombardment must be necessary for the fabrication of c-BN film.

We are developing a surface passivation process of Si by atmospheric-pressure plasma oxidation at low temperatures. To realize effective surface passivation, it is important to increase the fixed charge density (Qf) in the film as well as to reduce the interface state density (Dit). In this work, we have investigated the effects of N addition into the SiO2 film on Qf and Dit. Electrical characterization results have shown that the addition of N increases both Qf and Dit. Therefore, it is important to optimize the formation and annealing conditions to obtain effective surface passivation films in the atmospheric-pressure plasma oxidation process.

It was found that the crystal orientation membrane, which is exposed to ion beam, can orient liquid crystal. This process can reduce a static electricity and debris, which are induced in the usual rubbing methods, to realize a display with higher resolution. In this study, the orientation of liquid crystal on polyimide, which was irradiated by Ar beam, was examined. The beam energy was higher than the previous studies.

This paper describes the influence of electrolyzed reducing water on the surface of optical glass. First, we threw light on the etching characteristic of electrolyzed reducing water on the surface of optical glass by the comparative immersion experiments with NaCl electrolyzed reducing water and NaOH solution. The results show that as for the etching effects on optical glass, NaCl electrolyzed reducing water is same as the NaOH solution and becomes minute. Next, we threw light on the influence of NaCl electrolyzed reducing water on the surface shape, chemical composition and chemical bonding of the surface of optical glass, by the observation using the AFM image and the result of ESCA. The results indicated that NaCl electrolyzed reducing water did not have a influence on the surface shape, chemical composition and chemical vonding of optical glass. By the wash experiment, the effectivity of electrolyzed reducing water in case of grinding material particulate removal wash was verified.

This paper describes the influence of Na2SO4 EO water (electrolyzed oxidizing water) on the surface of oxygen-free copper. First, the etching characteristic of Na2SO4 EO water on the surface of oxygen-free copper was made clear by the comparative immersion experiments with NaCl EO water and chemicals. The results show that as for the etching effects on oxygen-free copper, Na2SO4 EO water becomes stronger than chemicals and becomes weak than NaCl EO water. Next, the influence of Na2SO4 EO water on the surface shape of oxygen-free copper was made clear by the observation using SEM and AFM image. The results indicated that Na2SO4 EO water is different from NaCl EO water and did not have a big influence on the surface shape of oxygen-free copper. Lastly, by analyzing the surface, Na2SO4 EO water is different from NaCl EO water and doesn't form alien substances such as chloride on the surface of oxygen-free copper was made clear. Therefore, Na2SO4 EO water is wide in the application scope, compared with NaCl EO water.
