Title: Light-emitting-element driving circuit
Inventor: TAMURA MITSUO
IPC: H01L33/00
Filed: 1986-05-21
Abstract: PURPOSE:To make it possible to perform high-speed, large-current switching and to prevent the temperature change of current by a simple temperature compensating circuit, by constituting a current switch by a pair of FETs, and constituting a constant current source by a bipolar transistor. CONSTITUTION:A semiconductor-laser driving circuit is constituted by GaAsFETs Q1 and Q2 forming a current switch and an Si-transistor Q3 forming a constant current source. A pulse current flowing through a semiconductor laser LD is controlled by a base potential VB of the Si-transistor Q3. The current can be perfectly controlled within a range of 0-Vss (source potential). The temperature change of the current is readily controlled by using a temperature compensating diode D1. Thus the high speed switching of a large current can be performed. The temperature of the current can be prevented by a simple temperature compensating circuit. An IC circuit can be implemented as a light- emitting-element driving circuit on one chip, by using the GaAs hetero-bipolar transistor.

Title: Method for controlling air conditioner
Inventor: OGAWA YOSHIAKI
IPC: F24F11/02
Filed: 1992-05-11
Abstract: PURPOSE:To maintain a high power factor and suppress higher harmonic currents, by comparing the instantaneous value of the wave form of an input current with the reference value for the instantaneous value, which depends on the input current, and by performing ON-OFF control of a switching element based on the difference between the instantaneous value and the reference value. CONSTITUTION:By a sensing circuit 9 for sensing the instantaneous value of an input current, the input current and the instantaneous value of the wave form of the input current are sensed, and the reference value for the instantaneous value, which depends on the input current, is read out from the memory part of a microcomputer 13. Then, the sensed instantaneous value is compared with the reference value, and a switching element 5 is so controlled that the instantaneous value is made equal to the reference value. As a result, the ON- time of the duty cycle of a predetermined switching pattern is increased, or is kept as it is, or is decreased. Thereby, the wave form of the input current can be made nearly sinusoidal and nearly inphase with an input voltage, and a high power factor can always be maintained, and concurrently, higher harmonic currents can be suppressed.
