Title: Circuit breaker
Inventor: MORIWAKI HIDEAKI
IPC: H01H9/54
Filed: 1992-08-05
Abstract: PURPOSE:To keep electricity running even if a circuit breaker is set to work in a condition electricity leakage continues in the case it is determined that the leakage is due to an insignificant trouble by connecting a latching relay in series with a pulling out coil. CONSTITUTION:Electricity running is shut between the terminals u1, v1, w1 and the terminals u2, v2, w2 by excitation of a pulling out coil 8 through a pulling out system at the time electricity leakage happens. A mechanically holding type latching relay 15 is connected in series with the coil 8 and when electricity is led to run a coil 15A, a b-contact point 15B is opened and even after no electricity runs in the coil 15A, open state is kept by the work of a lock system. At the time a first electricity leakage happens, a circuit breaker works for shutting by the excitation of the coil 8 to shut the electric circuit and the circuit of the coil 8 is automatically shut by the relay 15. Consequently, in the case it is determined that the electricity leakage is due to an insignificant trouble, even if the circuit breaker works as electricity leakage happens, pulling out operation is not carried out and electricity is kept running.

Title: Power source circuit for xenon flash lamp
Inventor: MIYAMOTO MAKOTO
IPC: H05B41/32
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately charge a main discharging capacitor by charging the capacitor at a later speed than a predetermined charging speed until a voltage value of the capacitor arrives from a predetermined voltage value at a target voltage value. SOLUTION: A stored charge of a main discharging capacitor Cm is discharged by irradiating a lamp 2, and charging of the capacitor Cm is started. A control signal is given from a control circuit 5 to an output circuit 4 to control the circuit 4, thereby charging the capacitor Cm. A voltage value of the capacitor Cm is fed back to a control switching comparator 6 and a control stopping comparator 7. The comparator 6 compares a voltage value of finishing a rapid charging with a voltage value of the capacitor Cm, outputs an inverted signal to the circuit 5 when arriving at the voltage value of finishing the rapid charging to narrow a pulse width of the control signal, thereby decelerating a charging speed from the circuit 4 to the capacitor Cm. Thus, charging of the capacitor can be rapidly and accurately conducted.
