On-machine measuring system of accuracies of a deep-hole is developed using a lathe. The system consists of a laser interferometer set behind a head stock and the measuring head with a pentaprism and a corner prism. The corner prism is fixed to a stylus. The stylus scans a hole wall of a workpiece set on a carriage toward tangential direction. The movement of the stylus perpendicular to the hole wall is detected by the interferometer. A laser beam from the interferometer goes through a hole of the main spindle and is deflected by a pentaprism to the corner prism. In this research, factors, which cause measurement errors, are disclosed and a measure to counter the errors is discussed.

In this study, to make the best use of merits of natural language, we aim to propose a methodology for supporting conceptual design using a structured dictionary composed of hierarchal structures for verb/noun. In this first report, we classify the function dividing process within the conceptual design, and formalize the function operational patterns. Based on these patterns, we define the verb/noun hierarchal structures. Concretely, we report that the function dividing process can be classified into ″division with decomposition″ and ″division with causal relation,″ and that four operational patterns can be formalized. Then, we show the defined verb/noun hierarchal structures for supporting conceptual design.

Consumers regard the total value from a package of products and services as more important than that from products alone, because the material needs in society are largely met. That is to say, products and services are inextricably linked, and finding the methodology and tools to design products and services on a common platform is imperative. Under these circumstances, studies on Service Engineering (SE) have focused on the effective integration of products and services. SE provides a methodology from the viewpoint of engineering and makes it possible for designers to develop design solutions without relying on trial and error. In spite of its great importance, few methodologies to support designing in consideration of the relationship between products and services have been proposed. The authors have suggested a problem-solving framework integrating products and services. In this paper, detailed design procedures to implement the framework are proposed.

Vitrified superabrasive stones containing cerium dioxide (CeO
2) were made and their performances were evaluated through the superfinishing of optical glass. Experiments showed that CeO
2 stones would have mechanochemical reaction with optical glass. After 30s superfinishing of CeO
2 stones, surface roughness of the glass was 2 nmRa, and there were almost no scratches on the glass. As the temperature of superfinishing rose, the finishing ratio rose, and finishing ratio at 313 K was 1.1. In addition, the removal rate also rose as the temperature of superfinishing rose, and removal rate at 313 K was 7 μm/min. Those results indicate that CeO
2 stones are highly effective to finish optical glass.

The single-layered diamond wheel with suitable abrasive grain positions can improve the removal rate and the wheel life. The purpose of study is to develop the control technique of diamond grain positions on the wheel surface. We propose the setting method of diamond grains, in which grains with a constant pitch on a plane move onto the surface of wheel base using on electrostatic force. We investigated the effects of applied voltage or gap on the setting accuracy of grain by fundamental tests putting diamond grains onto the base plane with constant pitches.

To digital cameras, mobile phones with a camera, CD/DVD players and liquid crystal displays, optical parts such as aspheric lenses, free form surface lenses, light guiding plates, prism sheet and micro lens array, etc. are applied. These are ultra precision parts that have curved surface or precise form, and the accuracy influences the performance of the products.These parts are manufactured in molding processes. To secure the accuracy of the molds that have curved surface or precise form, suitable ultra-precision machines and quantification of the accuracy such as form accuracy, surface roughness or surface quality are indispensable. This paper describes present conditions about ultra-precision machines that correspond to curved surface, especially aspheric surface or precise form machining, accuracy and measurement.

Application of micro patterning of phospholipids on an electrode and electroformation technique has an advantage of generation of size dispersed liposomes. In this paper, a new micro-fabrication method of micro spots on a Teflon film (Teflon AF , Dupont) was described to realize such phospholipids micro-patterning. This new method was based on the two techniques. The one was that the photoresist (OFPR-800, TOKYO OHKA KOGYO CO., LTD.) was baked before spin-coating. The other was that Teflon surface without photo resist film was fabricated by the cavitations effect using ultrasonic bath. In the traditional micro-fabrication methods of Teflon film, surface metallization or surface modification was needed; therefore, these processes led to the heavy environmental loads or the wettability change of Teflon film. In this new method, the wettability of the Teflon was kept during the process (The contact angles of distilled water and paraffin oil on Teflon was 114° and 70°, respectively.). Then the phospholipids were put on the spots, and a micro-patterned phospholipid on an ITO glass was realized. Giant liposome was generated using Electroformation method (10Hz, 5Vp-p)on it. This process will contribute to reduce the effects on the environment.

Recently, automation of polishing work is expanding. But, as for the polishing work intended for the curved surfaces, hand polishing is still dominant. Therefore, this study deals with automating the polishing process for curved surfaces with unknown curvatures using industrial robot. In this paper, a method that autonomously adjusts the tool angle related to the workpiece surfaces by the industrial robot was examined. Actually, the detecting accuracy of the grinding force data and its direction were improved. As a result, the tool angle decided by the grinding force was obtained precisely and the finishing accuracy of the curved surface polishing was improved. Moreover, the polishing work was done to unknown curved surfaces of various shapes.

The demand of extremely thin wafer is increasing with the development of the miniaturization and high degree integration of ULSI. Current thinning technologies are facing great challenges with the continuous decrease of thickness of Si wafer. In this study, an integrated cup shaped grinding wheel (ICGW), which was combined high machining efficiency grinding with diamond segments and damage free grinding with chemo-mechanical grinding (CMG) segments, was developed to achieve high quality extremely thin Si wafer fabrication. Grinding experimental results show the minimum obtained Si wafer thickness was down to 15μm with the surface roughness (Ra) less than 0.7nm by using the developed ICGW.

This study aims to develop and propose an oscillation controlled lapping method, which uses a small diameter lap tool and is classed in the single wafer lapping system, as a effective method to achieve high precision controlled lapping of large size silicon wafer. Our previously paper shows the fundamental controlled lapping characteristics under both the theoretical and the experimental examinations. On the other hand, the lapping characteristics are affected by the slurry flow. Therefore, this paper describes the relation between the slurry flow and the lapping characteristics of the proposed method based on a series of lapping and observing experiment.
