IPC: F04B39/00
Filed: 1987-04-03
Abstract: PURPOSE:To improve the damping effect in pressure pulsation by forming a plurality of holes opened into a noise arresting chamber onto a steel plate and forming a hole communicating to each hole onto a gasket and preventing the intrusion of solder material into a throttle passage without accelerating the wearing-out of a press metal mold or avoiding the need of high precision in press molding. CONSTITUTION:A plurality of holes communicating to each noise arresting chamber are formed on a steel plate 12, and a hole communicating to a plurality of holes is formed on a gasket 9. Therefore, an exceedingly small throttle passage for the communication with each noise arresting chamber can be formed between the steel plate 12 and a cylinder block 6, without carrying out the press molding for forming a small recessed part for the throttle passage on a steel cover plate 13. Therefore, the accelerated wearing-out of a press metal mold or the need of high precision in the press-molding can be prevented, and the intrusion of solder material into the throttle passage is prevented, and the damping effect in the pressure pulsation can be improved.

Abstract: PURPOSE:To enable a true ionic current caused due to pressure to be read by constituting an extractor-type ionization vacuum gage by installing an ion-collecting electrode below an ion-drawing hole and inserting an ionic-current controlling electrode between the ion-drawing hole and the ion-controlling electrode. CONSTITUTION:An ion-drawing hole 4 is provided in the center of the lower end of a bell-like ion-drawing electrode 3. An ion-collecting electrode 5 surrounded by an ion-reflecting electrode facilitating collection of ions, is installed below the ion-drawing electrode 3. A proper electric potential is produced by inserting a grid-like ionic-current controlling electrode 7, formed by the use of a meshy material or the like, between the electrodes 3 and 5 so as to read a true ionic current caused due to pressure. As a result, the factors of measurement limit can be completely removed by 100% modulation of ionic current, thereby pressures of 10<-14>-10<-15>Torr can be measured.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming fine metallic electronic circuit pattern by which a very fine metallic thin film pattern image can be formed easily at a low cost in a uniform film thickness and with a less line width variation. SOLUTION: In a method for forming a metallic image, a metallic thin film is formed on a substrate carrying a fine resist pattern formed on the surface of the substrate by using a photoresist material by precipitation by bringing an alkaline aqueous solution prepared by mixing a water-soluble metallic compound with a reducing compound so that the oxidation potential of the reducing compound may become lower than the reduction potential of the metallic compound into contact with the substrate. The treatment with the alkaline aqueous solution is carried in two continuous stages by separately using two kinds of alkaline aqueous solutions having different activities. Thereafter, the resist pattern is stripped off from the substrate and a fine metallic thin film pattern is formed.

Title: Tension controller
Inventor: NISHIDA MICHIFUMI
IPC: G11B15/43
Filed: 1992-04-07
Abstract: PURPOSE:To satisfactorily suppress tensional fluctuation even in the case of steep acceleration and deceleration of a tape speed and speed variation of a tape take-up reel. CONSTITUTION:A rotation speed commanding value of a 1st reel 1 causing no tension fluctuation is obtained by a rotation speed calculating means 18 from a rotation speed of a 2nd reel 2. Moreover, an accelerating torque value required for changing a rotation speed of the 1st reel 1 to be equivalent to a change of the rotation speed commanding value of the 1st reel 1 is obtained by an accelerating torque calculating means 19, and the 1st reel 1 is driven under feed forward control as a central function by using this accelerating torque value. As a result, since the 1st reel 1 follows with almost no time-lag in accordance with a rotating state of the 1st reel 1, the tension fluctuation can satisfactorily be suppressed without depending upon a control characteristic of the 2nd reel 2.
