Title: Disk rotating/stopping mechanism
Inventor: NAKANISHI SEIKI
IPC: G11B19/22
Filed: 1988-11-07
Abstract: PURPOSE:To realize a simplified rotating/stopping mechanism by utilizing a mechanical mechanism utilizing the opening/closing action of a cover. CONSTITUTION:When the cover 8 is opened in a clockwise direction, a gear 11 is rotated in a counterclockwise direction, and a lever 12 is moved in a direction of arrow head B. A brake arm 13 is rotated in the counterclockwise direction, and a boss 133 is abutted with the outer peripheral end face of a disk 3. The boss 133 is pressed by a spring 14, and is brought into contact with the outer peripheral end face, which reduces the torque of the disk 3. When the cover 8 starts to open, the projecting part 122 of the lever 12 extrudes a boss 131 in the direction of B, and the arm 13 is rotated in the clockwise direction, then, the boss 133 is separated from the outer peripheral end face of the disk 3. In such a way, the arm 13 performs the role of a break by interlocking with the opening action of the cover 8. By employing such constitution, it is possible to stop the inertial rotation of the disk by providing only a disk reproducing device with a simplified component.

Abstract: PURPOSE:To facilitate the troubleshooting of a fault by transferring fault information occurred in a decentralized terminal equipment to a master station when the fault of the terminal equipment is restored and storing once the faulty content in a memory by the master station and then transferring and storing it in an external storage device. CONSTITUTION:If a fault takes place in a slave station 10, a fault detection/ management section 11 writes a fault data including the content of the fault and its occurrence time into a fault memory 12 and when the fault is restored, a transfer signal is sent to a communication controller 13, which reads the fault data from the fault memory 12 and transfers it to the master station 20. The master station 20 sends the received fault data to a slave station fault management section 21 from a communication controller 25 and the management section stores the fault data in a memory 23. If a fault takes place in the master station 20 itself, the master station fault detection/management section 22 writes the content of fault and the occurrence time as the fault data into the memory 23. The fault data of the master station and slave station stored in the memory 23 is transferred and stored to a magnetic disk 31 via an interface at a required period or a proper period.

Abstract: PROBLEM TO BE SOLVED: To stabilize a high voltage and to shorten a recovery time to a regular operation mode by driving a charge pump circuit with a clock from a self- exciting oscillator circuit at a regular operation mode time and from the outside at a stand-by mode time. SOLUTION: At the stand-by mode time, a stand-by control circuit 3 makes a stand-by signal STBY '1'.
