In order to fabricate polymer-based microstructures such as microchips for Micro Total Analysis System (µTAS) and micro-optical elements with feature sizes on the order of micrometers, we have been developing a microimprint technology with a fine nickel (Ni) mold instead of a conventional photolithography technique. In the present work, an electroplating apparatus with electrolyte injection nozzles has been developed in order to achieve high deposition rate in an electroforming process. Moreover, the applicability of a novel fabrication process of imprint molds was examined. In this technique, a Ni microstructure to be replicated from a structured master is fabricated as an integral part of a stainless-steel support frame structure during electroplating. This offers a relatively rapid technique for fabricating imprint molds.

In order to realize cellular function analysis on a chip-base system, we have been developing a newly designed AFM probe in which a conventional sharp tip is superseded by a hollow silicon dioxide (SiO
2) microneedle. The probe will be capable not only of performing AFM measurements but also of introducing desired biomolecules (nucleic acids, proteins, etc.) into living cells and extracting biomolecules expressed in the cells. In the present work, bioprobes were successfully fabricated by employing microfabrication technique of microneedles with a sharpened tip and electrostatic field-assisted direct bonding technique. Moreover, the insertion performance of the microneedles into a gelatin as an artificial cell and the ability of AFM measurements were examined.

Aiming to use in fabrication process for micro-fluidic devices, micro forming of micro channels on to polytetrafluroethlene (PTFE) plates have been performed by hot embossing. A series of experiments were conducted with different forming conditions. The results of this work implied that the increasing heating temperature and pressure will determine the replication accuracy of micro channel in depth, and the pressure holding time at heating temperature will determine the replication accuracy of that in width. Consequently the replication accuracy depends strongly on the forming conditions.

The purpose of this study is to fabricate a micro-fluidic chip made of fluorocarbon resins. In order to seal micro-channels for sending fluidic sample without spill, it is necessary to closely attach a thin film of fluorocarbon resin to a microfabricated fluorocarbon resin substrate. Therefore, the thermocompression experiments to attach two thin films of polytetrafluoroethylene (PTFE) were conducted first in this study. Furthermore the peeling test was also performed to measure attachement strength. As a result, the maximum attachment strength was about 7 N/cm. And it was also found that the attacment strength depended strongly on the heating temperature.

In order to fabricate ultra fine structures with different kind of shape on the metallic materials surface, a hybrid metallic micro rolling process to transfer micro patterns onto metallic materials surface is developed. Nano Plastic Forming (NPF) on pure aluminium (Al 99%) combined with coating technique is used to produce the Nickel dies for the rolling process. Experimental works with 0.1 N-1.0 N indentation load variations and 2.5 um-7.5 um pitch variations using knife edge diamond tool are conducted to study the feasibility of this technique. Based on the experimental results, the feasibility of this method to fabricate microstructures on metallic materials surface is concluded.

An application to visualize 3D time series data is developed using methods analogous to CT scan. 3D space is sliced with parallel planes to create group of 2D sliced time series data where change of time is expressed by color differentiation. Image processing method is used to analyze the data and each layer is re-stacked to restore the 3D data. GPU is used to process 2D images by parallel processing, taking advantage of its large and fast memory capacity. This approach is applied to simulate CNC milling.

We present a method for viewpoint registration by painting interfaces. The users specify the region of interest where they want to see. The algorithm computes viewpoint so that not only the region of interest faces the front but also the ROI is fitted into the window. Since the algorithm uses only the depth buffer, our method is particular useful for large data which is taken much time to render.

When ferrous material is cut by diamond tool, it is well known that a diamond tool is worn severely. The purpose of this research work is to machine a diamond by utilizing this wear. However, the shape on the machining surface of the ferrous material is deformed by cutting with diamond. Then, this deformed shape is transformed to the surface of diamond. As a result, the desired shape of diamond is not obtained. The ferrous material shaped its surface by another shaping tool to improve the deformation. This shaping of ferrous material surface is carried out while processing the diamond. Therefore the shaped surface of ferrous material is transformed to the diamond. A machine tool for this research is designed and assembled by myself. And the desired flat shape of diamond is obtained by the experiment with this machine tool.

The purpose of this study is to develop a new method for the micro fabrication by crystal growth. In this study, sodium chloride crystals are selected as the crystallization material. The relationship between the crystal forms and condition of solution are investigated. As a result, five types of crystal are formed. They are columnar, rectangular, pyramidal, unregularly and spherical shapes of crystal. Then the growth rate is investigated as to the rectangular crystal. Because shapes of crystal must be combined obtaining desired fabrication. For example, the combination of columnar and rectangular shapes crystal is carried out. As a result, they can be combined.

Recently, production efficiency has been increased and it changed to the times, when the thing overflows. As a result, diversification of consumer needs and demand forecasting became more important. But, SMB(Small and Medium sized Business), convenience stores and supermarket etc are few introduction of the demand forecasting system. Because the demand forecasting system is expensive, and the cost-benefit performance is not clear, therefore it is difficult to introduce. For this reason, we propose the inexpensive demand forecasting system for the SMB & the stores and it is easy to use by setting some parameters.

In optical and optoelectronic products such as digital cameras, mobile phones, and high-density optical disc systems, many optical lenses are used. Recently, glass lenses have been needed increasingly compared to plastic lenses in view of good optical characteristics and stability to environmental changes. In the present work, steel molds plated with NiP (nickel-phosphorus alloy) which have been used for molding plastic lenses are applied to mold glass lenses in order to produce low cost glass lenses and diffractive optical elements (DOE) made of glass. It is possible to mold glass lenses by NiP-plated mold under the appropriate conditions.
