Title: Power source protecting circuit
Inventor: KUWAJIMA MAMORU
IPC: H02M1/00
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a power source protecting circuit which can arbitrarily connect an AC adapter, without interrupting power supply to a load side and protect a power source circuit from overcurrent, even if the AC adapter is connected at any time. SOLUTION: A timing circuit 21, which outputs a signal for a time corresponding to the magnitude of a primary side voltage change of a power source circuit 2 and a voltage detecting circuit 22 which drives a current restraining means 30 when a signal from the timing circuit 21 is received, are installed. When the primary side voltage is increased instantaneously by the connection of an AC adapter, the current restraining means 30 prevents an overcurrent from flowing into the power source circuit 2. When the possibility of the overcurrent is eliminated, the timing circuit 21 resets the current restraining means 30, so that a power source circuit 2 can continue operation as it is, when a load becomes high.

Title: Switching method for optical connector
Inventor: ODA TAKAHARU
IPC: G02B6/38
Filed: 1990-12-07
Abstract: PURPOSE:To reduce switching time of an optical connector by turning off a switching means before the movement of the first connector is completed and at the same time, by decreasing the moving speed, and setting the moving speed to approximately zero at the preset moving position. CONSTITUTION:When abnormalities are generated on an optical communication line on an optical connector 1 side, a movable holder 13 is first moved back. Then, a switching solenoid 14 gets actuated, and an elevating stage 12 elevates by making a parallel translation along optical connectors 1, 4. Before an optical connector 2 ceases work, the switching solenoid 14 is turned off, and at the same time, a brake solenoid 15 is driven and the speed of the optical connector 2 is decreased. As a result, the elevating speed becomes approximately zero when the elevating stage 12 is elevated by the preset amount of elevation. Thus, the vibration of the optical connector is suppressed in the switching operation, enabling abutting connection of optical connectors immediately after switching.
