Abstract: PURPOSE:To obtain an approximately equal level of intensity among electric fields generated at each position by setting a fixed distance between adjacent electrode fingers of a comb-shaped electrode used in a surface acoustic wave device. CONSTITUTION:Electrode fingers 2a and 3a extended from comb-shaped electrodes 2 and 3 cross to each other, and the distance between these adjacent fingers 2a and 3a, i.e., the distance G between electrode fingers of different polarities is set constant at each position.

Title: Method for preventing sticking
Inventor: MIYATANI TAKASHI
IPC: B24B7/04
Filed: 1983-04-05
Abstract: PURPOSE:To prevent a workpiece from sticking to an upper abrasive wheel when raising said upper abrasive wheel and from suffering damage by polishing the parallel planes of said workpiece simultaneously and jetting out a fluid against said workpiece through through holes of said upper abrasive wheel after the polishing is over. CONSTITUTION:After a workpiece 1 is polished to a desired thickness, an introduction pipe 22 is connected to a compressed air source by closing a selector valve 23 and opening a selector valve 24, and compressed air is jetted out instead of an abrasive liquid through a plural number of through holes while a lift drive mechanism is operated, raising an upper abrasive wheel gradually in the direction of arrow 27b. Thereupon, compressed air is blown between the upper abrasive wheel and the workpiece, which is kept pressed to the lower abrasive wheel 3 and the upper abrasive wheel can be raised up to its original position without sticking to the workpiece 1. Thus, since the workpiece is prevented from sticking to the upper abrasive wheel, the damage or breakage resulting from its falling can be prevented, improving the yield.
