Title: Dc power unit
Inventor: AIZU SUMIICHI
IPC: H02M3/28
Filed: 1987-12-02
Abstract: PURPOSE:To ensure a stable operation of load by providing a diode characteristic circuit for permitting the forward voltage of a quiescent time control voltage to pass and for obstructing the reverse voltage thereof, and by superposing the output on the output of a phase compensating type error amplifier to supply the superposed output to the reference voltage input terminal of a pulse width modulation circuit. CONSTITUTION:This unit is provided with a diode characteristic circuit 27 for permitting the forward voltage of a quiescent time control voltage VDT of a quiescent time control circuit 12 to pass and for obstructing the reverse voltage thereof. Then, the output voltage of the circuit 27 is superposed on an error voltage Ve of a phase compensating type error amplifier 8. The superposed output is supplied to the reference voltage input terminal of a pulse width modulation circuit 10. With a start command signal VNF satisfies the starting condition, the error voltage Ve lowers according to lowering of the control voltage VDT. However, because the control voltage VDT is obstructed by the circuit 27, the error voltage Ve depends upon only the output of the error amplifier 8. Therefore, according to the correlation between the triangular wave signal VT of a triangular wave oscillation circuit 9 and the error voltage Ve, the pulse width control is started and the output voltage V0 of a smoothing circuit 5 becomes a stable DC voltage.

Title: Switch device
Inventor: NAKAYAMA ICHIRO
IPC: H01H1/40
Filed: 1989-11-25
Abstract: PURPOSE:To reduce the difference in the frequency of mutual contact and lessen that of mutual abrasion degrees by composing a switch device with a contact piece, having plural contact parts in one contact piece, and a switch substrate facing the contact piece and having contacts the number of which is fewer than that of the phases of a rotating body to be detected. CONSTITUTION:A switch substrate 1, in which contacts 1a, 1c, 1d, 1e, 1f, and 1g of which one corresponds to every two places of the phase of a rotating body to be detected are formed at equal intervals, is linked to the unshown rotating body at 1:1 to be rotated. A contact piece 2 has contact parts 2a and 2b which contact each contact on the substrate 1 so as to be electrically conductive to detect a rotation phase. Here the rotation of the substrate 1 in a direction 5 causes the contact 1a, connected to the contact part 2a, to be rotated to a position 1b of a broken line to contact the contact part 1b. Because thus one contact on the switch substrate connects the contact piece 2 two times per rotation, all twelve places of the rotating body can be detected with six contacts.

Title: Protection relay
Inventor: HAYASHI TAKANOBU
IPC: H01H83/02
Filed: 1994-11-16
Abstract: PURPOSE: To use an auxiliary relay having large contact capacity but slow operation time by turning on the contact thereof after the finish of the counting process of a relay operation timer. CONSTITUTION: When a relay operation time elapses according to a relay operation timer 5, a soft output section 6 actuates an auxiliary contact 7 for sending an instruction to trigger an actual breaker. After the elapse of the relay operation time according to the operation of the timer 5, an auxiliary relay operation timer 5a starts to count an auxiliary relay operation time. Also, when an ordinary accident current I2 flows, the operation counter T1 of the timer 5 starts to count a relay operation time t1 and after the finish of the counting process, the operation counter T3 of the timer 5a starts to count an auxiliary relay operation time t2 . Concurrently, the section 6 outputs a signal. In this case, the current I2 is not reset, even after counting the time t2 with the counter T3 and, therefore, a signal is outputted from the section 6 over a time longer than the time t2 .  As a result, a signal for actuating the contact of the auxiliary relay 7 is outputted to trigger the breaker and prevent the occurrence of an accident.
