Title: Clamp device of flexible disk
Inventor: OGURA SUSUMU
IPC: G11B17/028
Filed: 1984-01-13
Abstract: PURPOSE:To prevent the breakage of a disk center hole by setting the outer diameter of a contact part between a collet and the inner circumference of a disk center hole at the value slightly smaller than the inner diameter of the center hole and forming a truncated conical projection at the bottom part of the opening of a spindle hub. CONSTITUTION:The outer diameter of a contact part 7 between a collet 8 and the inner circumference of the center hole of a flexible disk 4 is set slightly smaller than the inner diameter of the center hole. Thus no extra power is applied to the inner circumference of the center hole when the collet 8 is put into the center hole. When the collet 8 is completely set in, the inner circumference of an opening at the tip of the collet 8 is expanded by the sloping surface of a truncated cone 11 of a spindle hub 2. At the same time, a base part 7 is also expanded and presses the inner circumference of the center hole. Then the hub 2, the disk 4 and the collet 8 are connected completely as soon as the center matching is obtained among them. The flexion of the collet 8 toward the lower part of the inner circumference of the center hole owing to the part 7 can be practically neglected. This prevents the breakage of the disk center hole.

Title: Variable gain amplifier
Inventor: KOBAYASHI TERUO
IPC: H03G1/00
Filed: 1982-01-20
Abstract: PURPOSE:To perform gain control by a digital signal by intermitting the output signal of an amplifier through a switch, smoothing and feeding its output signal back to the amplifier, and varying the opening and closing time ratio of the switch. CONSTITUTION:The output signal V0 of the operational amplifier 13 is intermitted through the switch 14. The switch 14 is turned on and off by a gain control signal 16, whose output pulse signal V'0 is smoothed by a smoothing circuit 15 to feed the smoothed signal VF back to an input of the amplifier 13. When the crest value of the signal V'0 is V0, pulse width is (t), and its period is T, signal VF=(t/T)XV0. When the gain of the open loop of the amplifier 13 is sufficiently large, an input signal VI becomes equal to the feedback signal VF, so VI=VF= (t/T)XV0. Therefore, the gain G of the amplifier 13 is equal to V0/VI=T/t and the gain of the amplifier 13 depends upon the duty ratio of the pulse width of the gain control signal 16.
