Title: Magnetron sputter electrode
Inventor: IWASHITA KATSUHIRO
IPC: C23C14/35
Filed: 1987-12-04
Abstract: PURPOSE:To improve the effective consumption rate of high-frequency electric power at the surface of a target by providing a metallic backing plate to the rear of a target, viewed from a vacuum-vessel side, and fitting a casing having an electromagnet built-in to the above backing plate. CONSTITUTION:A backing plate 2 is provided to the rear, viewed from a vacuum vessel 12 side, of a quartz target 1, and this backing plate 2 is fixed with screws 9 to casing 7 containing electromagnet. A voltage is impressed on the coils 3, 4 of the electromagnet to generate a magnetic field in which the lines of magnetic force are regulated so that they are in parallel with the target 1 surface. When a high-frequency voltage is applied from a high-frequency electric power source 29 to the casing 7, this voltage is impressed via the screws 9 on the target 1. Since a target electrode is electrically shut off from the electromagnet, the high-frequency electric power can be effectively consumed at the target 1 surface. As a result, sputtering can be carried out by producing stable plasma at the surface of the target 1.

Title: Braking device for vehicle
Inventor: SATO MASAMITSU
IPC: B60T8/40
Filed: 1986-12-22
Abstract: PURPOSE:To prevent a high oil pressure from being exerted as a kick back pressure on a master cylinder, by a method wherein an input oil pressure chamber is communicated to an oil chamber, the volume of which is increased during working of antilock control by means of a modulator. CONSTITUTION:When a modulator 2 performs antilock control, the volume of an input oil pressure chamber 14 is decreased according to approaching movement of a first piston 13 to a partition wall member 6. Thereby, although an oil pressure in the input oil pressure chamber 14 is increased, and is going to return through an inlet oil passage 15 to a master cylinder M, since the volume of an oil chamber 49 communicated to the input oil pressure chamber 14 is increased according to antilock control, a part of working oil in the input oil pressure chamber 14 is guided to the oil chamber 49, and an oil pressure in the input oil pressure chamber 14 is prevented from increase. Thus, a high oil pressure is prevented from being exerted as a back pressure directly on the master cylinder M, and a kick beck pressure is prevented from being exerted on a brake pedal P.
