IPC: H03M11/24
Filed: 1984-03-06
Abstract: PURPOSE:To recognize the application of a switch with simple constitution and less number of leads by providing a time constant circuit giving different time constant to each of plural switches to be identified to detect its charging or discharge time. CONSTITUTION:The switches 6a, 6b, 6c to be identified are provided and a pulse signal of a prescribed period is applied to a base (a) of a transistor (Tr). When the switch 6a is thrown at a time (t), the Tr is in the on-state and a capacitor C is short-circuited. When the level of the base of the Tr is at a low level, the charging is started and a potential at a point B is increased. When the voltage exceeds a reference voltage VC, an output C is produced in a voltage comparator 5. Since the time constant is changed at each switch, the time consumed until the output of the voltage comparator 5 reaches a high level is different and which switch is depressed is discriminated by measuring the time.

Title: Switching power supply circuit
Inventor: HAYAZAKI KIYONOBU
IPC: H02M3/335
Filed: 1981-03-25
Abstract: PURPOSE:To achieve a switching power supply with small size and high performance through a simple constitution, by using a charge preparatorily charged to a small size and large capacitance of capacitor as a starting power supply, in a switching power supply having a self-generating auxiliary power supply. CONSTITUTION:A capacitor 4 is charged with an input voltage between input terminals 1a and 1b, but a transistor 15 is not operated because no 2nd output of a transformer 8 is presented. When switches 7a and 7b are turned on, the charge in the capacitor 4 gives a bias to a control circuit 19 and a converter is operative. Then, the power supply circuit keeps normal operation. When the output voltage of the auxiliary power supply section is taken greater than a clamp voltage of a diode 3, the capacitor 4 can always be charged. In this case, even if the switches 7a and 7b are turned off, the power supply circuit keeps the operation, and the operation control of this power supply circuit can be made by the gate switching of a driving circuit 18.

Abstract: PURPOSE:To obtain an excellent display effect even if there are defects in respective picture element units by locally covering the surfaces of display electrodes facing display picture element electrodes to be bright point defects with light-shieldable thin films, by which the bright point defects can be changed to black point defects. CONSTITUTION:Si gates 301, Al source lines 302 and transparent picture element electrodes 303 consisting of ITO(Indium Tin Oxide) are formed on a quartz substrate 305.
