Title: Magnetic disk device
Inventor: KOGA NAOKI
IPC: G11B17/038
Filed: 1991-10-21
Abstract: PURPOSE:To prevent the deformation of a magnetic disk caused when the cap of a spindle motor is tightened resulting from the reduction in thickness of the magnetic disk associated with the increase in capacity of a magnetic disk device. CONSTITUTION:The thickness of magnetic disks 1a, 1b, and 1c is increased toward the cap 4 and bottom of a spindle motor 2. Therefore, the deformation of the magnetic disks can be suppressed and the magnetic characteristics of the disks become nearly the same on their upper and lower surfaces. At the same time, the capacity of this magnetic disk device can be increased, because the inner peripheral side radius of the magnetic disks can be reduced.

Abstract: PROBLEM TO BE SOLVED: To suppress wasteful electric power consumption and inhibit a heater from unintentional operation by installing a control means which switches an electric power switching means to an electricity non-supply state while responding after a prescribed period from the time when the heater is switched to non-operation state by a heater switching means. SOLUTION: When an electric power source button 4 is pushed continuously for 2 seconds, a power circuit 7b is turned on and an electric power source lamp 40 is lighted. In the case an operational knob 5 is already at an adjustment position, a buzzer 8 is operated for 1 second to inform erroneous operation and the electric power circuit 7b is turned off. In the case the operational knob 5 is at a turn-off position, a timer starts counting time and when the knob 5 is still at the turning off position even after five minutes, the power circuit 7b is turned off. On the other hand, in the case the operational knob 5 is operated at the adjustment position within five minutes, current is passed to the heater 3. After one hour passes while the adjustment position 5 being not turned back to the turning-off position, the heater 3 is turned off and the buzzer 8 is rung.  In the case the heater 3 is turned off during operation by the operational knob 5, the electric power circuit 7b is turned off after five minutes to prevent wasteful consumption of power.

Filed: 1990-10-11
Abstract: PURPOSE:To continuously mold compressible powder wherein each individual joint does not separate easily by pressure-molding powder every supply into a hole mold by means of a punch having a recession and protrusion shape in its tip, and receiving them by an intermittently falling receiving metal piece, and then pressing them out of the lower part of the hole mold, and finally laminating moldings into a continuously joined body. CONSTITUTION:A powder supplier 12 serves to receive a constant quantity of powder 10 from a hopper 13 and supply it into a hole mold 3 formed in a mold plate 1. When the powder supplier 12 moves rearward, a punch 4 rushes into the hole mold 3 for compressing the powder 10 at constant high pressing forces, whereby, on the upper surface of a pressure-molded item, a recession and protrusion surface is formed in accordance with the tip shape of the punch 4. As a receiving metal piece 9 moves downward at a constant distance, the punch 4 comes upward, and powder 10 is supplied again on the upper surface of a molding 14a within the hole mold 3 by means of the supplier 12, and the punch 4 acts to compress the powder 10. In this manner, a continuously joined body 14 comprising each individual molded item 14a-14g is formed successively repeatedly, and after the joined body 14 of pressure powder is made at a predetermined length, a final molded item 14g is pushed out of the lower part of the hole mold 3 by means of a punch. The continuously joined body 14 is formed such that the recession and protrusion of the joined surface are joined fittedly, resulting in not separating readily.

Inventor: HASHIMOTO SEIJI
IPC: H04N5/361
Filed: 1990-10-15
Abstract: PURPOSE:To reduce a dark current by fixing the potential of a main electrode area at reference potential before operating a reset means which resets plural transistors. CONSTITUTION:The reset operation of a photoelectric converter is performed by a first reset operation which resets the plural transistors comprehensively by energizing insulating gate type transistors provided at every neighboring transistor comprehensively.
