A prototype of radial encoder to measure runout of rotating axis has been developed. The radial encoder was composed of a concentric circle diffraction grating disk and a micro encoder head. They were respectively mounted on the spindle axis and XY-table of a nano/micro machining center. The fundamental characteristics of the radial encoder were investigated by experiments. It has been found that the prototype has measuring resolution of 0.1um and a capability to measure the rotational accuracy of spindle.

This paper describes a practical controller design method for precision motion system. To this date, the authors have proposed and studied a nominal characteristic trajectory following controller (NCTF controller) as a practical and user-friendly controller design method for PTP positioning. In this paper, the improvement of the NCTF controller design method for precision motion control is introduced. The improved controller has an almost similar structure and is designed using the similar design procedure to the previous one. The characteristics of the improved control method are experimentally evaluated with two ball screw mechanisms from tracking, contouring and positioning results. The experimental results show the improved NCTF control systems generally achieve better tracking and contouring performances than a conventional PI-D and NCTF control systems. In 0.25Hz and 100nm radius circular motion, the experimental tracking errors were smaller than 10nm.

When super positioning precision is demanded in an aerostatic lead screw, the manufacturing accuracy of the male screw and the female screw which are the bases of the system is requested extremely strict. However a high precision screw cannot be made with the grinding technology which the mainstreams method of manufacturing precise screw, when the profile of frank surface becomes important point. In this study, a super hand finishing method with exact precision is suggested, from this suggestion the device for super finishing of the male screw is designed and produced. The outline of this device and the results of the super finishing will be reported in this paper.

We study micro fluidic device using polyimide resin film and laser process machine. In this report, we created a device that sucks bloods by a needle and injects them into channels for observing deformability in artificial capillary-vessels. The substrate was made by laminated resin films on the soda glass. And channels as vessels and periphery channels were fabricated by laser process machine. After that, we inserted aφ0.5mm×25mm needle into the point of periphery channel. The device size including the needle is 90mm width,26mm length and 2mm height.

Vibratory linear micro-feeder as one of the micro-mechanism consists of the only one-piece construction by shim member or spring strips as the main member. The vibration angle can be given by crank or zigzag shape of the rectangular bended leaf spring at both track ends. The feeder with the thin shim plate track has the vibration characteristic which is equivalent to high rigidity track feeder. Normal feeding was confirmed by the 0603 tip capacitor in trial.

Recently, the researches of painless function needle are advanced to treat disabilities due to a cerebral disorder. The painless function needle can move freely into a brain, and it can give an electrical excitement and medicine to a brain cell directly. This needle must be flexible and accommodate to a living body. We use a hair for this purpose. The hair has working that defends bodying from the change of surroundings and the wound, and then it has a flexible, high reversibility. In the last report, we gave the hair a resin coating and metallic plating, and made neuron probe. In this report, the neuron probe was applied to the cell activity, and the penetration hole was formed in the hair.

This paper describes the improvement of the fabrication method of the MEMS optical switch proposed by the authors. Its basic switching unit consists of two glass substrates which have many electrodes on the surface and a belt-shaped thin film mirror between the glass substrates. The thin film mirror is deformed and driven by electrostatic force. To realize a multi-channel optical switch by combination, the improvement of the assembly accuracy and the solution of low repeatability problem are important. As the solution to these, the following two approaches are examined. One is the integration of the electrode array and the thin film mirror on the glass substrate. The other is the assembly of the parts using servo mechanism. Then, the characteristics of the fabricated optical switch are evaluated.

The manipulation of molecules is a crucial prerequisite for the emerging field of molecular nanobiotechnology. This paper reports measurements that characterize the immobilization of 48 kilobase-pair lambda DNA onto lifted-off microelectrodes by high-voltage and high-frequency dielectrophoresis. Measurements of voltage- and frequency-dependent immobilization of DNA onto microelectrodes by dielectrophoresis show significant reduction in the response as the frequency increases from 200 kHz to 1 MHz or decreases from 200 kHz to 100 kHz and also as the electric field is lower or higher than 0.4 Vp-p/m. We find that the immobilization and elongation of the DNA molecules is restricted by the geometry of the gap, and that by decreasing the electrode gap size, the DNA molecules have less chance for both immobilization and stretching. Further, we discuss two potential mechanisms for both immobilization and elongation of DNA molecules. The produced electrodes with both random microscopic peaks and modified smooth edges are utilized to show the effect of electrode edge roughness. The results imply that more DNA molecules can be immobilized by microelectrodes having rough edges. The experimental results are discussed with suggested improvements to microelectrodes geometry and dimensions.

Molecular self-assembling using biomolecules becomes one of the important technologies for fabrication of nanostructures in the bottom-up techniques. This paper describes the DNA rings-positioning onto silicon substrate based on scanning probe lithography using Atomic Force Microscope (AFM) and the DNA rings-transformation using the super coiled structure of biotin-conjugated DNA ring. In the case of DNA rings-positioning, an experiment has been performed using partially oxidized silicon substrate as anchor points and biotin-conjugated-DNA rings. Anchor points are fabricated periodically on silicon substrate using AFM. After coating 3-aminopropyl triethoxysilane (γ-APTES) onto anchor point, DNA rings are positioned onto the anchor points. In the case of DNA rings-transformation, super coiled DNA rings are fabricated using biotin-conjugated-DNA rings and ligation protocol. After these procedures, the DNA rings-positioning and DNA rings-transformation was confirmed by an AFM.

In this movement, not only high accuracy but also high quality finish up in a short machining time are requested for large size work-piece as press molds for automobiles. The MCR-H (Hyper) double-column machining center was developed to satisfy these requirements. Linear motors are adopted in the feed-axis of MCR-H, and the technologies for high speed, high accuracy are used. We introduce these technologies in this paper.
