Title: Erasing device for magnetic recording information
Inventor: FUJIWARA YASUHIRO
IPC: G11B5/024
Filed: 1983-10-13
Abstract: PURPOSE:To erase not only high frequency record, but also low frequency record easily and efficiently by supplying an erasing current while decreasing the relative speed between a magnetic head and a magnetic recording medium gradually. CONSTITUTION:When a magnetic head 10 is positioned on a track on a disk 1 to be erased in erasure mode, a switch 11 is placed at a side 11b, a switch 12 is set at a side 12b, and a switch 13 is connected to a side 13a. A switch 14 is turned on to charge a capacitor 21, and when a switch 8 is turned off, a current supplied from a power source 7 to a motor 2 is cut off. The motor 2 is therefore to stop, but the capacitor 21 is discharged, so the motor is reduced in speed comparatively slowly. Thus, while the turning speed of the disk 1 is reduced gradually, an erasing current of relatively low frequency is supplied to the magnetic head 10 at the start of erasure.

Filed: 1984-09-12
Abstract: PURPOSE:To eliminate adverse influences of scanning speed variance components in a wide frequency range including high-frequency components by providing a scanning speed detecting means, etc. and correcting a read signal in accordance with the scanning speed variance. CONSTITUTION:A scanning speed detecting means 50 detects the scanning speed of an optical beam emitted from a scanning means 30 to a read object and outputs a signal related to this scanning speed. An operating means 60 operates signals outputted from a reading means 40 and the means 50 and outputs a corrected read signal S as the result. That is, a read signal P outputted from the means 40 is multiplied by a speed signal V outputted from the means. Thus, variance components in the read signal due to the variance of the scanning speed of the optical beam 22 can be removed. Adverse influences of scanning speed variance components are eliminated in the wide frequency range including not only low frequency components but also high-frequency components to perform sufficient compensation.

Title: Control device for line pressure in automatic transmission
Inventor: KIUCHI MORIO
IPC: F16H61/14
Filed: 1982-10-30
Abstract: PURPOSE:To aim at reducing shock upon gear-shifting, in a line pressure control device in a vehicle automatic transmission provided with a lock-up device, by delaying the cut-back of line pressure upon releasing operation of lock-up in association with gear-shifting. CONSTITUTION:In a lock-up range, a lock-up solenoid 20 is temporarily deenergized upon gear-shifting so that a lock-up control valve 16 is changed over to its normal position by a spring 29, and therefore, an output shaft 3 and a transmission input shaft 2 are coupled together by a torque converter 4. Simultaneously, hydraulic pressure in a pilot chamber in a pressure modifier valve 27 is lowered so that return force toward the normal position is brought about. This return force is restrained until the relative force relation is reversed due to the counter hydraulic pressure in an accumulator 41, and therefore, the throttle pressure is maintained to be exerted to the pilot chamber 12a in a regulator valve 12 so that the cut-back is delayed. Due to this cut-back, shock upon gear- shifting is reduced.
