Patent JP-H0488842-A (JP)
Title: Power source system for vehicle
Inventor: INOUE HIROSHI
IPC: H02J7/14
Filed: 1990-07-31
Abstract: PURPOSE:To prevent an excessive charging current from flowing to a safety device by a method wherein the charging current flowing to the safety device is suppressed for a prescribed time after a generation start signal is received from a detecting circuit detecting the start of generation by an alternator. CONSTITUTION:When an alternator 1 starts generation, a detecting circuit 21 detects the start and outputs a generation start signal Ss. This generation start signal Ss is inputted to a timer amplifier 23. Thereby the timer amplifier 23 puts a circuit opening-closing mechanism rl in a forced state of circuit closure for a prescribed time. Accordingly, part of a charging current Ic flows through a load circuit 15 and is consumed in electrical equipment 11a for a vehicle. The time for which the circuit opening-closing mechanism rl inside the timer amplifier 23 is put in the forced state of circuit closure continues until a function guaranteeing current of a safety device 7 and the charging current Ic cross each other, and during this time, a current IL lower than the charging current Ic flows through the safety device 7. Therefore the function guaranteeing current Is of the safety device 7 can be made low.

When the voltage Rf of the resistor Rf becomes equal to a reference voltage VT1 at a time t0, a set/reset signal of a flip-flop 4 becomes 'L', and control transistors Q16, Q26, Q36 are turned ON. That is, the bases of drive transistors Q13, Q23, Q33 are grounded, and drivers 1U, 1V, 1W are not operated, and the voltage VRf of the resistor Rf becomes zero. Simultaneously, since a transistor Q52 is turned OFF, a capacitor C is started to be charged through a transistor Q49.

IPC: H02H7/20
Filed: 1989-08-03
Abstract: PURPOSE:To blow off a fuse for a desired interrupting time, and to protect load by connecting the series circuit of a small-capacity fuse and a resistor in parallel with the contact of the load and a circuit breaker. CONSTITUTION:When driving currents I from a control circuit CTL1 and a transistor Q2 are made to flow continuously, a small-capacity fuse F2 is blown off after a fusing time set by the resistance value of a resistor R1. Currents are made to flow through the trip coil of none-fuse breaker NFB1, that is, from a power supply +V - a node B - the trip coil of the none-fuse breaker NFB1 - the resistor R1 - the transistor Q2 - a ground. The breaker NFB1 is tripped, and abnormal currents are interrupted. Accordingly, a linear motor coil L2 can be protected from the abnormal rise of a temperature or burning. Normally, the potential of a point A and a point B is equalized and currents are not made to flow through the breaker NFB1. The fusing time can be set at a desired value.

Abstract: PURPOSE:To enable display with high contrast and high quality at fine picture element pitches by forming layers which constitute data lines and layers which constitute picture element electrodes in such a manner as to have the layer disposition parted most in the thickness direction of a substrate. CONSTITUTION:A thin metallic film is deposited on the glass substrate 1 and the data lines 8 are patterned and formed. A CVD silicon oxide film and a thin metallic film are deposited as an inter-layer insulating film 13 thereon and gate electrodes 2 and timing lines 3 are patterned and formed. A gate insulating film 4 and a thin amorphous silicon film 5 are then patterned and formed. A transparent conductive film is further deposited thereon and the picture element electrodes 6 are patterned and formed. After contact holes 14 are opened, a thin metallic film is deposited and source electrodes 7 and drain electrodes 9 are patterned and formed. The layer which constitute the data lines and the layer which constitutes and picture element electrodes, therefore, has the layer disposition parted most in the thickness direction. The spacings between the data lines and the picture element electrodes are thereby narrowed in plane and the quantity of the light transmitting through said spacings is decreased and, therefore the display with the high contrast at a high density is enabled.
