Patent JP-H0487557-A (JP)
Title: Switching power unit
Inventor: INOUE MASAYOSHI
IPC: H02M3/28
Filed: 1990-07-26
Abstract: PURPOSE:To prevent a driving transistor from breaking down when the voltage of a commercial power source increases abnormally by turning the driving transistor off with a control transistor which is turned on when the voltage of the commercial power source increases. CONSTITUTION:When the voltage of a commercial power source 1 is approximately as high as the rated voltage, a control transistor 28 is turned off and operated as usual. When the voltage of the commercial power source 1 increases abnormally and the voltage across a capacitor 4 exceeds the Zener voltage of a Zener diode 26, a current is passed through the Zener diode 26 and the control transistor 28 is turned on. When the control transistor 28 has large hFE, it is saturated sufficiently, the base-emitter voltage of a driving transistor 7 is set to 0.2V, and the driving transistor 7 is turned off. Therefore, the driving transistor 7 stops self-oscillation and is prevented from breaking down without passing an overcurrent therethrough.

IPC: F24D17/00
Filed: 1990-07-26
Abstract: PURPOSE:To make a turning on of a hot-water tap effect a switchover to the hot-water supply mode even when a hot-water system is in the automatic bath filling-high-temperature water- replenishing mode and also enable supplying hot water in a large quantity by providing a first cold-water bypath and a second cold-water bypath having a second flow-control valve and a flow switch with the function to detect a flow of water. CONSTITUTION:A first cold-water bypath 32 is provided in parallel with a heat--exchanger 9 so that by heating a small quantity of water to a high temperature at a heat-exchanger 9 and by mixing the hot water with cold water supplied through the first cold-water bypath 32 a large quantity of hot water can be supplied at a prescribed temperature. When a hot-water tap is turned on while the mode is for supplying hot water to a bath-filling hot-water supply channel 25, a flow switch 12 detects a flow of water through a second cold-water bypath 33 from a cold-water inlet 23 to the hot-water tap and switches modes from hot-water supply to a bathtub 19 to hot-water supply to the hot-water top. In a second cold-water bypath 33 a solenoid valve 13 is open while the bathtub 19 is being replenished with hot water and after the flow switch 12 has transmitted a signal denoting a flow of water to a controller 2 the solenoid valve 13 is closed in order not to cause the cold water flowing through this channel to lower the temperature of the hot water supplied through a hot-water channel 24. The solenoid valve 13 opens again when the hot-water top is turned off and the supply of hot water is stopped.

Abstract: PURPOSE:To permit desired formation of positive and negative pictures by the simple operation of changing over, for example, an external switch by using a developer having conductivity and magnetism, a developer carrying body having magnets, and a photoreceptor having a transparent conductive substrate. CONSTITUTION:A developer carrying body 8 is a developing sleeve of metal having magnets in the inside, and is connected to an electric power source 10 in such a way that the transparent conductive substrate 7 side of a photoreceptor having, for example, n type photoconductive layer is made negative, by which DC bias of relatively low voltage is applied.
