Title: Magneto-optical recording medium
Inventor: MAENO KIMINORI
IPC: G11B11/105
Filed: 1989-05-11
Abstract: PURPOSE:To obtain the magneto-optical recording medium which is lowered in thermal conductivity, maintains C/N and has high writing and reading out sensitivity with a small recording power by adding titanium or copper to aluminum and forming a reflecting film. CONSTITUTION:A magnetic film 15 is laminated by a sputtering method on a substrate 11 and the reflecting film 17 is formed on this film 15 by a sputtering method using the material formed by adding the titanium or copper to the aluminum. The thermal conductivity can be lowered without degrading the reflectivity possessed by the aluminum as the film 17 is formed in such a manner. The C/N is, therefore, maintained without lowering the reflectivity possessed by the reflecting film and the recording power is decreased by lowering the thermal conductivity. The magneto-optical recording medium having the high writing and reading out sensitivity with the small recording power is obtd. in this way.

Title: Vacuum limiter
Inventor: UEMURA TSUGIO
IPC: F02M23/08
Filed: 1987-05-14
Abstract: PURPOSE:To make it possible to increase the amount of replenished air at the initial time of the valve opening period by communicating a space which is formed by an inner projection and an outer projection in a valve closing condition, with a vacuum chamber through an orifice having a fine flow passage areas. CONSTITUTION:In a vacuum limiter 7, during the idle operation of an engine 6 in which the differential pressure between a pressure in an atmosphere side passage 8a and a negative pressure in a vacuum chamber 14 is low, a valve 18 is closed. At this time, the atmospheric pressure acts only upon a surface 22 formed inward of an inner projection 19. Upon deceleration during high speed running, when the negative pressure increases in the negative pressure chamber 14 so that the differential pressure between itself and the pressure in the atmosphere side passage 8a increases, a valve 18 operates overcoming a spring 16. With this arrangement, the atmospheric pressure also acts upon a surface 23 through a gap between the inner projection 19 and a seat surface 13, and the pressure receiving area increases remarkably. Accordingly, during deceleration, the amount of valve opening is remarkably changed in accordance with a slight variation in negative pressure at the initial time of the opening period of the valve during deceleration, thereby it is possible to aim at enhancing the amount of replenished air.

Title: Tape feeding device
Inventor: WAKIYAMA KOJI
IPC: G11B15/43
Filed: 1989-05-12
Abstract: PURPOSE:To quickly stop the feeding of a tape without generating the slack of the tape by providing a state command circuit which outputs a take-up or stopping command to a first driving circuit and outputs a command to generate or to stop the generation of regular torque by receiving the output of a decelerating state detection circuit to a second driving circuit. CONSTITUTION:When the state command circuit 7 outputs the take-up command, the tape 1 is taken up on a take-up side reel by driving a take-up side motor 2b so as to keep the output of a tape speed detecting means constant by the first driving circuit 4. When the state command circuit 7 outputs the stopping command, the first driving circuit 4 sets the take-up side motor 2b at a free running state, and also, the second driving circuit 5 generates the regular torque at a delivery side motor 2a, then, tape speed can be reduced. When the tape speed is sufficiently reduced and a state less than regular speed is detected by a decelerating state detection circuit 6, the state command circuit 7 stops the output of the regular torque at the second driving circuit 5, then, stops the take-up operation of the tape 1. Thereby, it is possible to decelerate the tape speed in a short time.
