Abstract: PURPOSE:To provide overwrite S/N at about the same degree in the inside and outside circumferential parts of a disk and to permit recording of signals at high density to the disk by making the thickness of the medium in the outside circumferential part smaller than the thickness of the medium in the inside circumferential part. CONSTITUTION:The medium is formed to have the thickness smaller in the outside circumferential part than in the inside circumferential part. For example, a substrate 1 is a disk which has about 130mmphi outside diameter and 40mmphi inside diameter and is formed by subjecting the surface of Al having 1.9mm thickness to NiP plating to 50mum thickness. Co-20wt% Cr alloy is deposited thereon. The Co-Cr alloy 2 is a vertically magnetizable recording medium and permits recording and reproduction to the high density. The Co-Cr medium is formed to have 0.5mum thickness on the innermost circumference and 0.35mum thickness on the outermost circumference and in this manner the thickness on the outermost circumference is made smallest. Such distribution is obtainable by changing adequately the spacing between a sputter target and the substrate in the stage of sputtering the Co-Cr alloy.

Title: Middle voltage enclosed load switching device
Inventor: KURUTO GURIYUUNBERUKU
IPC: H02B13/02
Filed: 1982-03-02
Abstract: An encapsulated medium-voltage electrical load switching apparatus has four, three-position rotary switches, supported by pairs of opposing insulated half-shells, two-over-two in parallel alignment within a gas-filled sealed shut shell housing. The housing front and back have dome-shaped protrusions to maintain the seal against fluctuations in gas pressure. Bushings in the floor and ceiling of the housing, aligned with the switch face plane, provide gastight connections between the switches and external cables, enclosed fuses and transformer terminals. Switch control is provided by drives mounted on a plate at the front of the housing exterior which operate actuator arms that extend in a gastight way through the housing front and manipulate selector shafts that connect to set the switches into closed-circuited, open-circuited and grounded positions. Internal conductors establish connection from a cable through a fuse to a transformer terminal when the two upper switches and one of the lower switches are closed-circuited. The disclosed apparatus offers the advantages of low cost, compactness and freedom from maintenance.

Title: Density controller for copying machine
Inventor: FUJITA YUKITOSHI
IPC: G03G15/00
Filed: 1985-02-19
Abstract: PURPOSE:To uniform copy density up to the recovery of toner density by performing light quantity control and developing bias control over a light source and correcting toner density simultaneously with the start of toner supply in case of a decrease in toner density. CONSTITUTION:The toner density in the developing device of a copying machine is detected by toner density detectors 12a and 12b. If a signal showing a decrease in toner density is inputted from the detectors 12a and 12b while a copy signal showing the copying machine is in copying operation is inputted to a central processor CPU, the CPU outputs a toner supply signal to command a toner supply roller 13 to rotate, thereby starting supplying toner. At the same time, the CPU outputs a density control signal to correct the toner density by respective functions of a light quantity control part 5 or developing bias control part 14. If the toner density recovers during the toner supply, density control enters a temporary stop state until the toner density drops for the next time. The two detectors 12a and 12b are both used for fine toner density control.

Abstract: PURPOSE:To attain fine automatic focusing for both static and moving subjects by controlling power supply in accordance with the operation of respective operating members on the camera side and the lens body-tube side to control the number of times of focusing operation. CONSTITUTION:When a camera side switch 10 is turned on and electric power is supplied from a camera side battery 8, the output of a terminal E of a sequence control circuit 15 is inverted to the high level and power supply transistors (TRs) 9, 12 are turned on. Simultaneously, the terminal H of the circuit 15 is turned to the high level, a built-in D-type FF is set up and the status is stored, so that the terminal E is kept at the H level. In accordance with the operation of an LED24 to be turned on by the movement of the lens barrel through a circuit 19 at the time of automatic focusing, the D-type FF of the circuit 15 is reset and the terminal E is turned to the L level. Thus, power supply is stopped after one focusing. On the other hand, power supply is continued by a lens barrel side switch 40 at the time of power supply from a lens barrel side battery 38 until a counter built in the circuit 15 detects the prescribed number of times of focusing. Thus, both the static and moving subjects can be automatically and finely focused.

Filed: 1989-02-15
Abstract: PURPOSE:To always start the working of a microcomputer at an optimum working speed in accordance with the connection state of an oscillator by providing a means to discriminate whether the oscillator is connected or not. CONSTITUTION:A discriminating circuit 8 recognizes a fact that an oscillator is connected to a low speed oscillation terminal 4 by testing the level of the terminal 4. Then a control signal 9 is inputted to a system clock generating circuit 7 so that the circuit 7 starts its working at a low speed. Thus the circuit 7 starts its working at a low speed right after application of a power supply with use of a low frequency pulse 6. Then the circuit 8 also recognizes a fact that the oscillator is not connected to the terminal 4. In such a case, the signal 9 is inputted to the circuit 7 so as to start its working at high speed. Thus the circuit 7 starts its working at a high speed right after application of the power supply with use of a high frequency pulse 3. As a result, a microcomputer can start at a working speed suited to the connection state of the oscillator.
