Filed: 1988-05-31
Abstract: PURPOSE:To realize the synchronizing control among plural axes by designating plural axes undergoing the synchronizing control from of a prescribed NC program, putting a queing command into the NC programs corresponding to those designated axes, and applying the shift control to the corresponding movable part while securing the synchronism with the waiting command. CONSTITUTION:The NC programs 11a-11d are prepared in response to a movable part of a prescribed axis constitution and the numerical control parts 12a-12d perform the numerical control processing based on the programs 11a-11d to move each movable part. Then plural axes to undergo the synchronizing control are designated by a synchronizing axis command SANC put into the main NC program 11a. The queing commands WNC are put into the NC programs corresponding to those designated axes. Thus the numerical control processing is carried out while securing the synchronism with the command WNC and therefore the shift control is applied to the corresponding movable part. Thus the synchronizing control is attained even with the axes having the master-slave-subslave relation.

Title: Insulator for measuring amount of fouling
Inventor: MIYATA YASUHIRO
IPC: G01R31/12
Filed: 1990-05-25
Abstract: PURPOSE:To put an optical wave guide path in the same fouled condition as the surface of an insulator so as to measure the precise amount of fouling at real time by bonding an optical fibre for directing light to the optical wave guide path onto the surface of the insulator to bring the optical wave guide path into contact with the surface of the insulator. CONSTITUTION:Optical fiber sections 4 joined respectively to both sides of a wave guide path 1 are fixed to an insulator 2 via a bonding agent 3 so as to bring the wave guide path into contact with the surface of the insulator 2. Because in this construction no bonding-agent 3 or the like is used at the part of the wave guide path 1, the wave guide path 1 is fouled in the same fouled condition as a general insulator. The amount of fouling can accordingly be measured very accurately at real time. Besides, a groove having an outside diameter of not more than that of the wave guide path 1 may be formed in the surface of the insulator to install the wave guide path 1 in the groove, or the wave guide path 1 may be spot-welded to the surface of the insulator with a space held toward the insulator.

Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a film having stable dry peeling strength, good peeling properties in a high-speed zone, and good transparency with lower cost and without generating paper powder by providing a case composed of solventless silicone on a resin film by a specific amount per unit area. SOLUTION: A resin film is preferably a film having good dimensional stability to heat, by considering curing after transferring solventless silicone, or heat applied to a finished release film at the time of post-treatment such as tack treatment. A solventless silicone case requires 0.05-0.5 g/m<2> amount. If the amount of the solventless silicone case is less than 0.05 g/m<2> , stable dry peeling properties can not be obtained, and high-speed peeling properties are not improved. If the amount of the solventless silicone case is over 0.5 g/m<2> , blocking is generated on the finished release film, which inhibits the next process, or causes breaking of the release film.
