Title: Short-circuit protection circuit
Inventor: UENO KATSUNORI
IPC: H03K17/08
Filed: 1992-01-16
Abstract: PURPOSE:To attain the control of a main element due to a drive signal at the point of time when a signal fed to a drive terminal with an external circuit reaches zero or an inverse polarity by resetting a protection circuit. CONSTITUTION:When a load is short-circuited, a collector current of a main element 11 and a current detection element 11 increases further rapidly, a sensor potential rises together with the current increase and a protection circuit is activated. When a gate potential of a discharge MOSFET 2 rises almost similarly to the sensor potential, the protection circuit is operated and the main current is limited, the sensor potential is reduced and a gate potential of the MOSFET 2 is held by a diode 9 and a resistor. When a gate signal reaches 0, the gate potential of the discharge MOSFET 2 is reset to zero by a diode 12. That is, as soon as a voltage applied to a gate terminal 5 by the operation of an external circuit reaches 0V, since the protection circuit is reset, the restoration is immediately attained.

Title: Developer for electrostatic photography
Inventor: TSUBUSHI KAZUO
IPC: G03G9/13
Filed: 1989-01-12
Abstract: PURPOSE:To enhance image density, resolution, fixability and the like and to prevent strike through, offset and the like by using a a cyclopentadiene type polymer for a toner binder.

Abstract: PURPOSE:To enable the considerable reduction in the time required for the purge and the complete substn. of the atmosphere gas over the entire part in a furnace by introducing purging gas in each zone forming the continuous annealing furnace and sucking the gas in approximately the intermediate position over the entire part of the furnace. CONSTITUTION:The stop valve 14 of a gaseous AX piping 9 is closed to supply gaseous N2 of a prescribed pressure and flow rate into a gaseous N2 piping 8. Then the gaseous N2 is blown from the top and bottom parts in the heating part 2, primary and secondary soaking parts 3, 4, primary and secondary cooling parts 5, 7 and overaging part 6 of an annealing furnace 1 into the furnace. The suction of the gas in the furnace is started at this same instant through the piping 11 in the cooling part 5.

Title: Driving method and apparatus of electromagnetic pump
Inventor: TANAKA HITOSHI
IPC: F04D17/04
Filed: 1981-01-20
Abstract: PURPOSE:To enable an electromagnetic pump to constantly maintain its discharge power, irrespective of the variation of source voltage, by fixing the effective current value of pulse current wherein the source voltage of electromagnetic winding is added to the control input which acts to control the discharge power of the electromagnetic pump. CONSTITUTION:When a pulse signal is applied to the base of a transistor Q2 in way of a resistor R7 and the collector of the transistor Q2 is connected to the return side of an electromagnetic winding M, the pulse current Ip in the identical waveform to a pulse signal (b) is transmitted to the electromagnetic winding M, thereby, the electromagnetic pump is actuated. In this case, the pulse spacing (t) is reduced, because, when the source voltage Vcc rises, the control  input voltage Vd also rises, and the current effective value, which is fixed by  the pulse area of the pulse current, may not be changed even if the current  value of the pulse current Ip is increased, so that the discharge power of the  electromagnetic pump can be thus kept constant.
