We develop a small NC milling machine based on the concept of a micro factory. We try to manufacture this machine for using even in the laboratory where there are lot of amateur machine operators for getting trial machine parts. The small NC milling machine size is about 150mm×100mm×270mm. It is about 1/10 of the general milling machines. To evaluate this machine's performances we first make square parts:5mm×5mm×2mm and we make sure that this square parts accuracy is kept within 0. 01mm. We also make one of typical machine parts : a gear, and a circular pyramidal shape which is called a 2. 5 dimensional sample.

Most of conventional micro manipulators do not have multi purpose functions, sophisticated motions and powers as human being's hands do, and can do only simple works; stabbing, injection and pipette insertion and translation. The purpose of this study is to develop and to assemble a chopstick-type micro hand with much higher workability and compatibility toa conventional manipulator system applying a commertial video game controller pad which has multi-input gate for the micro manipulators. Our chopstick-type micro manipulator is designed referring to the actions of chopstick. When we use the chopstick, a piece of the chopstick at the side of forefinger moves mainly to manipulate an object. But a piece of chopstick at the side of thumb hardly moves at all and only supports an object. Our new chopstick-type micro manipulator can catch a erlass dummy cell (φ50μm) by two glass needle and top of the single finger micro manipulator can reach exactly to the center of dummy cells.

We have developed the wide range scanning tunneling microscope (STM) to measure surface topography of a diamond turned gold mirror, a gold coated float polished glass surface and so on. Three dimensional positioning of our STM device is achieved not by using a famous piezoelectric tripod, but by monolithic high precision wide ange translation mechanisms, which we call multi-compound parallel spring. One of strong points of this device is that capability of this specially fabricated X-Y stage is to measure over a sample area of 70μm×70μm and is easily cut from a monolith. We have got an information that each diamond tip trace straightness of the turned surface using a high precision air bearing lathe changes noticeably in the portion. This fact shows that we still have to improve not only such manufacturing conditions as tool radius, and the roughness of tool tips but also the surface finish machine environments especially vibrations.
