Abstract: PURPOSE:To improve drop of the input power factor when the power consumption of the same phase load has sunk, by varying the constants of circuit components of a noise preventive filter circuit, and furnishing a power factor control means to match the phase of input current with the phase of input voltage. CONSTITUTION:Through a noise preventive filter circuit 2, AC power is supplied to a power-variable power supply device A consisting of a smoother capacitor, inverter, etc., and a lamp l is lighted up with the high frequency output of this power supply device A, which thus makes dim control of the brightness of the lamp l is in response to the dim signal. The constants of components of the noise preventive filter circuit 2 is varied by a power factor control means, and the phase of the input current is matched with the input voltage. This allows the load side for the AC power supply to be the same phase load at all times even when the power consumption of the power supply device A has sunk, and thereby drop of the input power factor is improved.

Title: Color signal processor
Inventor: UCHIYAMA SHINICHI
IPC: H04N9/79
Filed: 1986-12-16
Abstract: PURPOSE:To prevent fading of a color or hue variation in the upper part of a television screen by supplying a burst gate pulse to a second burst gate circuit also the periods of both vertical synchronizing signal and equalizing pulse to use a third burst gate pulse generated from a horizontal synchronizing signal. CONSTITUTION:A switch circuit 21 switches between second burst gate pulses and third burst gate pulses corresponding to V pulses. So, since color burst signals are not present during a V pulse period, no second burst gate pulses are generated, however, burst gate pulses can be made supplied to a burst gate circuit 22 even during a V pulse period by using third burst gate pulses during the V pulse period. Accordingly, error signals can hardly occur in a phase comparator during a V pulse period because there is no color burst signals, and the control voltage of a VCO26 can be made in about normal level. As a result, a color fading or hue variation in the upper part of the screen at the time of reproduction can be prevented.

In this way, critical currents for the tunnel walls 5 and 6 are made different, and quasi- particles can be carried into a measuring instrument efficiently as a current. Therefore, the efficiency of the detection of the quasi-particles excited with light can be implemented, and the high sensitivity and the high speed characteristic of a superconductive light sensor can be implemented. The critical currents of the tunnel walls can be changed by changing the widths of the two tunnel walls 5 and 6.

Title: Semiconductor laser device and wave-length changing type ultrashort light pulse generator
Inventor: ODANI JIYUN
IPC: H01S5/00
Filed: 1988-11-28
Abstract: PURPOSE:To obtain short wavelength laser beam pulses having a high output and in a very short time by conducting mode locking by TM mode oscillation and coupling beam pulses with an optical guide type wave-length changing element. CONSTITUTION:Currents are injected to the active layer 10 of a semiconductor laser 16 from a power supply 38. Laser beams 40 emitted from a first end face 14 on which an antireflection film 15 is shaped are passed through a lens 42, a polarizer 44, through which only a TM polarizing component is passed, and an etalon 46 as a wave-length controller, and reflected by an external reflector 22 and fed back to the semiconductor laser 16. When inrush currents are modulated by the round trip frequency f=2L/C (in formula, C represents light velocity and L a distance between the end face 12 of the laser 16 and the reflector 22) of an external resonator, beam pulses 48 for a time (1ps or less) shorter than conventional devices are acquired. It is because the residual reflectivity of the antireflection film 18 is reduced at a TM mode. The beam pulses can be coupled directly with a wave changing element, thus acquiring short wave-length pulses having a high output.

Title: Production of thin oxide superconducting film
Inventor: TORII HIDEO
IPC: C01G1/00
Filed: 1987-11-27
Abstract: PURPOSE:To obtain a thin superconductor film having a superconduction transition point above the temp. of liq. nitrogen by a relatively simple method by applying a soln. of specified nitrates in mixed alcohol to a substrate, drying the soln., repeating the applying and drying stages several times and calcining the resulting layer in an oxidizing atmosphere. CONSTITUTION:A soln. of nitrates of barium or strontium, copper and lanthanoids in mixed alcohol is applied to a substrate and dried. The applying and drying stages are repeated plural times and the resulting layer is calcined in an oxidizing atmosphere to obtain an objective thin oxide superconductor film. This method is advantageous because the film can be synthesized under ordinary pressure without using a vacuum system. Since the molar ratios among the cations in the soln. to be applied are directly related to the chemical compsn. of the film, a thin superconductor film having a desired chemical compsn. is obtd. by controlling the molar ratios among the nitrates in the soln.
