Title: Discharge tube lighting driving device
Inventor: TOKUSHIMA AKIRA
IPC: H02M7/538
Filed: 1999-06-26
Abstract: PROBLEM TO BE SOLVED: To drive at high efficiency and at large power by combining with a high voltage booster by controlling a driving signal of a pair of N type and P type switching transistors generated with a PWM control IC of a pulse width modulation mode operation so that on-time of the N type is slightly longer than off-time of the P type by the driving of a piezoelectric transformer, and forming a reverse constitution in reverse operation. SOLUTION: Micro signals from a control part of a PWM control IC 1 having 16 pins using an oscillator-installed pulse width modulation control integrated circuit are formed so that on.off times are overlapped in a specified mode with a pair of switching transistors 3, 4. The signals are subjected to boosting with a flyback transformer 2 having primary and secondary windings, passed through a resonance circuit of a resonance transformer 5 and a resonance capacitor 6, and supplied to a piezoelectric transformer 7. A means for increasing a voltage rising ratio required by stacking of unit piezoelectric transformer is made unnecessary, and driving at about 90% efficiency and about 10 W power is realized without using burst light dimming type control having a noise generating source.

Title: Inverter circuit for motor
Inventor: TANAKA SHIRO
IPC: H02P6/08
Filed: 1992-08-17
Abstract: PURPOSE:To make the high-speed PWM control of an inverter circuit possible by a method wherein a positive signal transistor Tr, a diode and a capacitor, connected to the base of a positive side output transistor (Tr), are provided and an electric charge, accumulated in the capacitor, into which an OFF signal is inputted from a driving control circuit, is discharged to put the positive side output Tr OFF. CONSTITUTION:When an OFF signal is inputted into the base of a transistor Q61, the collector of the transistor Q61 is isolated from an emitter, the potential of the collector of the transistor Q61 is increased and an electric charge, accumulated in a capacitor C11 by an electric current 13, is discharged whereby a transistor Q11 is put ON by the discharge current 14. In this case, the base potential of another transistor Qu1 becomes same as the emitter potential of the same. Then, an electric charge, accumulated in a parasitic capacity (c1) between the emitter and the base of the transistor Qu1, is discharged whereby an electric current 15 flows. The direction of the current 15 is from the base to the emitter or a direction to put the transistor Qu1 OFF. On the other hand, the current 15 discharges the charge, accumulated in the parasitic capacity (c1). In this case, the transistor Qu1 is put OFF promptly.

Title: Semiconductor laser
Inventor: IWANO HIDEAKI
IPC: H01L21/205
Filed: 1986-09-16
Abstract: PURPOSE:To obtain a semiconductor laser, which has small oscillation threshold current density, generates single transverse mode oscillation and can be manufactured with excellent yield in a uniform large area, by specifying a buried semiconductor layer from the periodic table and changing the semiconductor layer into a semi-insulating compound semiconductor layer. CONSTITUTION:When a II-VI compound semiconductor layer 103 consists of ZnSl, it has index difference extremely larger than the refractive index of an active layer 109 composed of GaAs, etc., and the efficiency of optical confinement is improved, thus lowering injection current density. Since a II-VI compound semiconductor has an extremely large band gap, the resistivity of a thin-film through an MOCVD method is increased, and the buried layer 103 can prevent inJection currents completely. Consequently, threshold current density can further be lowered. The active layer 109 is inverted-mesa-etched in a striped manner, and the buried layer 103 is shaped, thus acquiring a flat surface. The width of the actual active layer 109 is made narrower than that of a resist pattern in a photolithographic process, thus resulting in a single oscillation transverse mode, then allowing stable laser operation.
