Title: Vibration preventive device of wire electrode in wire cut electric discharge machining
Inventor: INOUE KIYOSHI
IPC: B23H7/10
Filed: 1981-03-13
Abstract: PURPOSE: To prevent vibration of a wire electrode, by filling magnetic fluid between magnetic poles, providing the magnetic fluid between a wire guide and a work as a spacer and arranging the wire electrode extended through said magnetic fluid.  
     CONSTITUTION: A wire electrode 1 passes through guide rollers 3aW3c from a strage drum 2a to perform electric discharge machining between ship-shaped guides 6a, 6b, and is wound to a reel drum 2b. Spacers 10aW10d are provided between the ship-shaped guides 6a, 6b and a work 7, and these spacers 10aW10d consist of magnetic fluid 11 filled between magnetic poles 12a, 12b. Since the magnetic fluid 11 is magnetized to the direction vertically of the feed direction of the wire electrode 1, no resistance is provided for the feed of the wire electrode 1, and damper action is caused for lateral vibration. If the magnetized directions of the spacers 10a and 10c and 10b and 10d are arranged at a right angle, vibration of the wire electrode can be effectively prevented.

Abstract: PURPOSE:To prevent a capacitance part from being polished when an interlayer insulating film which is flat is formed by a method wherein a stopper layer whose polishing speed is remarkably smaller than that of the interlayer insulating film is formed at the upper part of an element or an interconnection arrangement, the interlayer insulating film is deposited on the surface, including the upper part of the stopper layer and the interlayer insulating film is polished and removed until the stopper layer is exposed. CONSTITUTION:A second-layer interlayer insulating film 19 which is composed of a BPSG film is deposited on the whole face of the capacitance part of a memory cell 12 which is composed of a lower-part electrode 13 and of a capacitance insulating film 17 and an upper-part electrode 18 which are laminated on it. After that, a stopper film 20 which is composed of a silicon nitride film is formed. In succession, a third- layer interlayer insulating film 21 which is based on a silicon oxide film is formed. After that, a polishing operation is executed, a difference in level is eliminated in a part in which the stopper film 20 is exposed, and a flat face 22 is formed. At this time, the polishing speed of the stopper film 20 which is composed of the silicon nitride film is slow by five to ten times as compared with that of the BPSG film as the second interlayer insulating film 19. Thereby, a capacitance part including the upper- part electrode 18 is not polished.

Abstract: PURPOSE:To bring the operating potential to steady-state in a short time by providing an analog switch turned on in a short time after the start of amplification of 1st and 2nd amplifiers and converging a potential across a capacitor to a steady-state value. CONSTITUTION:An analog switch Q is provided in parallel with a resistor RS2 and turned on for a short time after operational amplifiers A1, A2 are driven.
