Title: Output voltage stabilizing circuit of switching electric power source
Inventor: SATOU YUKINORI
IPC: H02M3/155
Filed: 1980-03-05
Abstract: PURPOSE:To make it possible to stabilize the output voltage at the time of no-load without increasing the load capacity of the switching electric power source, by constituting the circuit so that a no-load preventive current is made to flow only when load is not connected. CONSTITUTION:The terminal P4 of load Z12 is connected to the terminal P1 at the high potential side of the switching electric power source Z11, the terminals P5 is connected to the terminal P2 at the low potential side, and the terminal P6 connected to the terminal P5 is connected to the detection terminal P3. In this case, the base potential of the transistor TRQ11 becomes a low potential, the TRQ11 becomes a cut-off state, and a current flows into only the load Z12 from the electric power source Z11. When the load Z12 is not connected, the terminals P1, P2 are released from the terminals P4, P5, also the terminal P3 is also released from the terminal P6, a base current flows into the TRQ11 through the resistor R12, and the TRQ11 becomes an operation state. Accordingly, a current flows into the resistor R11 and the TRQ11 from the electric power source Z11, and it is prevented that the electric power source Z11 becomes no-load.

Title: Magnetic disk device
Inventor: SEO YOUSUKE
IPC: G11B21/10
Filed: 1983-02-23
Abstract: PURPOSE:To reduce position error generated by temperature difference between disk by detecting temperature difference between disks by a thermocouple, heating a head arm in response to an electromotive force produced in the thermocouple and controlling the amount of thermal expansion. CONSTITUTION:An electromotive force in response to the temperature difference of a space between disks, e.g., D1, and D2, is generated from different kinds of metals 11 and 12 constituting the thermocouple. The constitution is that a high gain differential amplifier 14 and a current drive circuit 15 receiving this potential difference flow a current in response to the temperature difference to a heater fitted to an arm at a low temperature side. When the heater 16 fitted to the arm is heated, a heater section attains automatic compensation by a heat deprived by wind or the like being balanced with the heating at the same time. The positioning error due to temperature difference is compensated by simple constitution in this way, allowing to improve the positioning accuracy.
