Filed: 1989-05-19
Abstract: PURPOSE:To simplify control of a light as compared with conventional methods and to facilitate a constitution by writing with a light or an electricity, and then obtaining its inverted signal by an electric control signal. CONSTITUTION:A pnpn light emitting element of OFF state is written optically or electrically, and an inverted signal necessary to process the later signal is obtained by an electric control signal. For example, it is written by a light, and the light is incident to a GND1 of a light emitting having a pnpn structure. Here, a P-type gate terminal of the GND1 and GND2 is connected to a terminal G, and an electric control signal is applied thereto. After the GND1 is turned ON by the light, the GND1 and GND2 alternately emit lights repeatedly each time a positive electric control pulse is applied to the terminal G. Thus, the control of the light is simplified as compared with conventional methods to facilitate its constitution.

Title: Discharge control circuit and series regulator
Inventor: TAKIMOTO HISAICHI
IPC: H02J1/00
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To gradually shorten the operating time width of an output transistor, by switching the output transistor based on the control signal inputted from the outside, and performing discharge operation based on stopping of the input of the control signal. SOLUTION: According to the decrease of output voltage VO, the voltage level of an input signal IN is decreased, but an input signal CS is further decreased. By action thus operated in a short time, an output OUT1 is placed in a condition fixed to an L level, and the output voltage VO is generated in a ground GND level. Accordingly, when a control signal CTL is placed in an L level, the output voltage VO, according to a decrease of voltage of the input signal CS, is decreased to the ground GND level based on control of a DC/DC converter 11 itself. Here, a time t1 required for decreasing the output voltage VO from fixed voltage to the ground GND level is almost determined by a time constant set by a capacitor 20 and a resistor R3.
