Applying large quantity of cutting fluids during cutting is characterized by problems in the immediate working environment and in waste disposal. These problems result in a large number of ecological problems and in a climate of increasingly strict work safety and environmental legislation. To reduce the quantities of cutting fluids, dry machining and near-dry machining should be replaced by a conventional oil supplying method. Near dry machining has been actually adopted in automobile manufacturing plant. However, mechanism of near dry machining had not been analyzed. It was proved by Kaneeda et al that near dry machining is able to realize using lubricant applying effect in ductile metal cutting. The purpose of this paper is to investigate lubricant applying effect during titanium alloy cutting.

In order to examine the effect of coolant′s oxidation potential on the lapping characteristics of difficult-to-machine material, S45C, SUS304 and Inconel713 were lapped by using a near-water with positive oxidation potential. The water-soluble coolant inflicted a severe adhesion of cutting chips onto the cutting edge. Using a near-water with positive oxidation potential much relieved the reaction between cutting chips and cutting edge. The lapping with near-water showed an excellent abrasive ability and Inconel713 showed a similar finishing surface as those of S45C and SUS304. However, the positive oxidation potential of near-water caused a rust formation on the surface of S45C. These facts indicate that the coolant with positive oxidation potential would have an excellent performance in the machining of difficult-to-machine materials, because it can prevent the adhesion of cutting chips onto the cutting edge.

Fine particles can be self-assembled only on the required part on a substrate by patterning the substrate with hydrophilic or hydrophobic materials and draw up from the suspension in which particles were dispersed. This study aims to make clear the influence of locally spread profile of suspension over hydrophilic area on the width of particles assembly. The pattern was fabricated on a substrate by microcontact printing hydrophobic material (OTS) on a silicon wafer covered with oxide layer. The pattern was line-and-space with various combination of the width of OTS. The suspension was water-based that contains polystyrene particles of 400nm with the concentration of 0.5%. It was found that the width of assembly is predictable by the observation of the thin and local spreading of the suspension.

Assembly of functionalized particles with surface modification has potential applications such as sensor devices. Dip-coating provides efficient assembly allowing on the specified position with hydrophilic/hydrophobic patterns. However, surface modification changes interaction between particles and/or particle-and-substrate, thus make the assembly difficult. This study firstly attempted to modify silica particles with the organic silane monolayer and protein to characterize the surface. Secondly, we attempted to assemble the modified particles on hydrophilic/hydrophobic patterned substrate by drawing up from suspension in which particles were dispersed. The hydrophobic particles assembled selectively along the pattern although the assembly had some defects. The protein-modified particles also could be assembled without detachment of protein.

This study aims to clarify the influence of surface topography on the photocatalytic reaction of TiO2 film surface. In this report, a textured TiO2 film was produced by conducting the anodic oxidation to the titanium plate with micro cutting grooves, and its wettabilty was evaluated. From a comparison, it was understood that the wettability of the above-mentioned TiO2 film is superior to that of polished and oxidized one. As a result, it is confirmed that the wettability of photocatalytic film can be improved by increasing both the surface roughness and actual surface area.

Microstructures with high aspect ratio are required to provide various functions such as control of wetting, adhesion and so on. In this study, we introduce a novel method of fabricating such structures with high throughput. Light curing polymer was spun-coated on a glass substrate and its viscosity was modified with soft-baking. The polymer was elongated with wires by applying upward motion after dipping into the polymer. Then, the polymer was dosed by UV light and cured. By using this process, fiber-like structures, of which diameter 10 m with aspect ratio over 8 typically, were fabricated. And we investigated the relationship between the diameter of the structure obtained and the yield.

This paper describes the effect of the rake angle of the cutting edge on the machinability of Ni-P alloy. As a result, it was found that the maximum groove depth and width with the cutting edge of 0 degrees. In addition, the aspect ratio depends on a point angle of the cutting edge and becomes about 1.5.

A sandwich tool for fabricating many numbers of minute grooves at one ultrasonic-machining process has been devised. The width of the groove can be decreased if the thickness of a tool tip for ultrasonic machining decreases.This situation, however, causes the problem of decreasing of the stiffness of the tool for ultrasonic machining. If a tool is made of a soft material, the surface damage of the workpiece by ultrasonic impacts of the abrasives slurry is little because the soft material absorbs the energy of the ultrasonic vibration. Then the sandwich tool is made by laminating thin-hard materials and thin-soft materials alternately. Thin-soft materials are necessary to control the stiffness of the whole of the sandwich tool. The width of the groove depends on the thickness of the thin-hard material and the distance between grooves depends on the thickness of the thin-soft material. In this report, the mechanism of the micro-grooving with the sandwich tool is explained, and some results of the investigation concerning the influence of the ultrasonic machining condition upon the characteristics of the grooves are shown.

Manipulation technology for single-cell analysis is becoming increasingly important for gene transfer application. Conventionally, single cell is sorted by flow cytometry and electroosmotic flow pump etc. However, these techniques do not allow the precise positioning of each cell.Herein, we propose a microfluidic device that uses surface acoustic wave (SAW) for manipulating single cells. SAW is excited by interdigital electrodes on a piezoelectric substrate, resulting in the vibration of the surface. SAW devices are fabricated on 128°Y-cut lithium niobate (LiNbO₃). The manipulation devices are made on the substrate with excitation electrodes and photoresist microchannels. Channels and electrodes are fabricated by photolithography and regular MEMS technology. Two interdigital electrodes are located on both sides of channel′s track, which has a circuit-track shapes with a width and a depth are 200 µm and 120 µm, respectively. When the electrode is excited at a frequency and voltage of 10.0 MHz and 20.0 V-pp, the cell flow is changed for right to left from a velocity of 113.5 µm/sec to -93.8 µm/sec respectively.

We aim to do blood sampling and blood test at the same time by any person at home in the future. In first report, we fabricated the vacuum micro channel for blood sampling, but the air bubbles were into the channel at experiment of ink injection. In this report, we fabricated micro channels with air extractor. As a result, we could draw ink into 10µm X 17µm channel without air bubbles.

Vertical-scanning interferometries using white light are widely used to measure 3D shape of small step-like objects with high speed and high precision. This type of interferometry is being refined for more precision, more speed and more stable even in vibrating environment. In this key-note speech, I summarize our research processes to obtain high-speed and high-precision performance in 3D-shape measurement. Our processes have included technologies using two color LED, new phase shift algorithm, and an optical path difference(OPD) meter. I briefly compare our technologies with newly proposed techniques. I hope my comparison will stimulate many kinds of discussions.
