Title: Method for sensing seismic coefficient of earthquake sensor
Inventor: TAKE TAKASHI
IPC: G01V1/00
Filed: 1980-07-12
Abstract: PURPOSE:To make a titled sensor simple and robust in construction, highly reliable and easy to maintain and handle by modulating the intensity of earthquakes directly by the opening and closing ratios of a switch and taking it out as a magnitude in the voltage of a electric storage device. CONSTITUTION:A switch 2 closes only at the part where the instantaneous value of vibration waveforms exceeds a constant value, a transistor 5 is conducting and constant voltage is generated in a resistance 6. A electric storage device 8 is charged by the voltage drop of the resistance 6 through a diode 9 and a resistance 10 and is discharged through the resistance 6, a diode 11 and a resistance 12. The voltage of the device 8 is the ripple voltage determined by charging and discharging actions and the opening and closing periods of the switch 2. The average voltage of the device 8 is taken out through a filter circuit consisting of a choke coil 13 and a storage device 14 and is being applied to the base of a transistor 15.

Title: Driving circuit for optical semiconductor element
Inventor: YOSHIDA AKIO
IPC: H01L33/00
Filed: 1989-04-13
Abstract: PURPOSE:To effectively drive at a high speed with an optical signal having severe variation by providing bias means having resistor group. CONSTITUTION:If a control input signal is a low level, the output, i.e., a connecting point B of a switching circuit 2 becomes a high level, a light emitting diode 1 is turned OFF, and an optical semiconductor element is not driven. When a control input signal becomes a high level, the point B becomes a low level. Since a transient current flows to the circuit 2 through speedup capacitor 3, and a resistor 4 of the diode 1 from a power source voltage at the transient time upon change of state of the point B, the switching time of the diode 1 is shortened to improve rising characteristic. When the signal becomes a low level, the point B becomes a high level, and remaining charge near the diode 1 is discharged and absorbed by transient current from the circuit 2 at the transient time. Thus, an optical semiconductor element can be effectively driven at a high speed for the signal including high frequency component of severe variation.
