IPC: B24B37/025
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To efficiently grind ceramic balls and to easily grind steel balls with high accuracy by mixing to grind the ceramic balls and the steel balls between the working discs.

Title: Machining device, and method for machining foamed resin member
Inventor: HAGIWARA KAZUMI
IPC: B23C3/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To highly accurately machine a foamed resin member by reciprocating a tool by a specified amount in a direction orthogonal to the center axis of the tool, advancing the tool in the direction of the center axis, and then moving the same in the direction of the center axis in a zigzag manner.

Filed: 1990-03-16
Abstract: PURPOSE:To realize the miniaturization of this encoder and the reduction in cost and high detection accuracy by providing a mobile object for forming a position information pattern of plural diffraction grating elements, a light beam projection system which projects a light on the mobile object and plural light receiving systems for its reflected light, and further providing a lens which image diffracting grating element reflected light on a corresponding photodetector. CONSTITUTION:The image forming lens 18 which image-forms reflected light from a diffraction grating element G at every track TR1 of a rotary disk on a corresponding sensor S1 of the photodetector 17 is provided between a beam splitter 15 and the array type photodetector 17. Then even when the intervals of the elements G are narrowed down to diverge reflected light by diffraction, that is absorbed by the lens 18 and the light is made incident on the element 17. Consequently, inter-track interference is precluded, and even when the track intervals are narrowed down, no misdetection is caused by the diffraction, so that the small-sized, inexpensive encoder with the high detection accuracy can be realized.
