Inventor: CHIKAMOTO TAKESHI
IPC: B24B1/00
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To chamfer thin material rapidly. SOLUTION: At the time of chamfering four angular parts of a workpiece W, rectangular thin material, by a chamfering machine 1, four grinding wheels 126A, 127B, and the like corresponding to each angular part of the workpiece W are arranged in corresponding positions, and the workpiece W is moved and passed among these grinding wheels to chamfer the workpiece W. The whole chamfering can therefore be performed only by passing the clamped thin material workpiece W once among the grinding wheels. The respective grinding wheels 127A, 127B, and the like are formed into chamfering angles by four dressing wheels 133A, 133B, and the like corresponding to four grinding wheels 127A, 127B, and the like, and the grinding wheels 127A, 127B, and the like are rotated around vertical shafts to chamfer the workpiece W.  The rotary shafts of the dressing wheels 133A, 133B, and the like are inclined by the chamfering angles to perform forming, and the dressing wheels 133A, 133B are rotated at high speed to form the grinding wheels and rotated at low speed to dress the grinding wheels 127A, 127B, and the like.

Title: Information recording and reading method
Inventor: MURASE CHIKAO
IPC: G11B7/00
Filed: 1988-12-05
Abstract: PURPOSE:To increase the data transfer speed up to such degree that it can be fit for the practical use by continuously changing the irradiated position of recording or reading light to record or read information. CONSTITUTION:In the method where the wavelength of light is changed to multirecord information in a prescribed position on a recording medium and multirecorded information is read out, the irradiated position of the laser light is continuously scanned to increase the data transfer speed up to such degree that it can be fit for the practical use. That is, when the irradiated position of the laser light is continuously scanned, the data transfer speed is increased because the spot is moved on the recording medium at a certain fixed speed. When the wavelength is scanned simultaneously with scanning of the irradiated position, it is unnecessary to scan the wavelength of the laser light at a high speed because irradiation of light different in wavelength to the same recording point is prolonged, and periods of respective scanning are not equalized to write and read information more effectively.

Abstract: PURPOSE:To enhance resolution in the sample direction by making proton beams via an acceleration tube pass through a slit or Q lens with a small aperture. CONSTITUTION:Proton beams coming from an ion source A advance through a vacuum space and are curved at right angles by a magnet B. Successively, the beams pass through an accelerating tube C in an adjustable speed tube part 3 so as to be accelerated and they pass through a slit 1 with an small aperture 14. Thus, very thin proton beams can be obtained. This slit can be replaced for a Q lens. Thereafter, the proton beams are deflected by a vertical scanning electrode 2 and a horizontal scanning electrode 4 and they impinge on a sample. Secondary electrons scattered from this impinging point are scanned by the electrodes 4 and 2, and they pass through the aperture 14 and the adjustable speed tube part 3 then functioning as a deceleration tube D, and they are curved by magnets E and F, and their energy Ea is measured by an analyzer G. Hence, resolution in the sample direction of a method of proton energy loss spectral analysis can be upgraded.
