Patent JP-S6452357-A (JP)
Title: Thermal switch
Inventor: KANEKO NORIO
IPC: H01H3/00
Filed: 1987-07-29
Abstract: PURPOSE:To obtain a thermal switch with the high precision of the operating temperature by inserting a superconductor between electrodes and switching the inter-electrode resistance to 0 or the normal resistance value at the superconductivity/normal conductivity transition temperature. CONSTITUTION:The resistance of a superconductor 1 becomes 0 when the temperature of the superconductor 1 is the superconductivity/normal conductivity transition temperature Tc or below, and two conductors 21, 22 connected to the superconductor 1 are turned on. When the temperature of the superconductor 1 is Tc or higher, the resistance of the superconductor is increased, and the resistance between two conductors connected to the superconductor is increased. A circuit can be turned off by the electric resistance or current change generated at this time. A thermal switch with a high speed and high precision is thereby obtained by utilizing the change of the electric resistance of the electric resistance near the critical temperature Tc.

Title: Monitoring device for set picture
Inventor: SHIMONO YOSHIO
IPC: H04N5/45
Filed: 1989-07-20
Abstract: PURPOSE:To remarkably improve resolution in a vertical direction and to clearly display a character, etc., on the slave screen of a large screen by generating a pseudo scanning line between original scanning lines in the area of the slave screen. CONSTITUTION:After a video signal inputted to a slave screen processing circuit 4 is digitized and is thinned and written on a VRAM 43, it is read out, and is superimposed on a master picture at a video output circuit 5, and is displayed on a CRT 9. At such a case, readout from the VRAM 43 is performed with a frequency of twice that of write, especially, second readout is performed synchronizing with a vertical direction beam modulation signal. As a result, the pseudo scanning line can be generated with a picture element read out at the second readout between the original scanning lines separately from an original picture element. Therefore, it follows that the number of scanning lines in the vertical direction can be doubled. Thereby, the resolution of the slave screen in the vertical direction is remarkably improved.

Abstract: PURPOSE:To perform smoothly a concentrating operation of used surface treating liquid, etc., and to facilitate cleaning of an apparatus used for the disposal by adding a specified amt. of sodium sulfate to the surface treating liquid and then subjecting the liquid to treatments including evaporation to dryness. CONSTITUTION:A waste liquid produced in a draining and discoloration- preventing stage of surface treatment of an article is subjected to treatments including evaporation to dryness after adding at least 1wt.% and effective amt. of sodium sulfate to the waste liquid. Recovery of alcohol by distillation, etc., or reduction of COD or BOD by electrolytic oxidation, etc., may be performed as prestage treatment for the evaporation to dryness, but the boiling and evaporation of the waste liquid in a heating kettle for distillation are caused more smoothly facilitating the recovery of solvent by the addition of sodium sulfate. Further, higher current efficiency is obtd. in the electrolytic oxidation, and corrosion of the apparatus is reduced. Deposition of evaporation residue to an inside wall of an evaporating vessel is also reduced. Moreover, generated residue solidifies in the bottom of the vessel and can be easily scraped off with a scraper, etc.

Title: Wireless connector
Inventor: HIBIYA KAZUCHIKA
IPC: H04B10/556
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To avoid ripple or voltage fluctuation even in the case of axis deviation between primary side and secondary side units or the fluctuation of a mutual interval by providing an offset part, with which light is not interrupted in transmission from the primary side unit, and supplying power for the secondary side unit with a solar battery output for photodetecting the offset part. SOLUTION: When a control signal C for instructing which one of sensors 21-24 of a secondary side unit 20 to transmit data is FSK, the control signal C is transmitted while combining frequencies f1 and f2. At such a time, a DC bias is added to the control signal C and the offset part is formed so that a primary side communication part 12 can continue turning-on through the offset part in spite of the presence/absence of the control signal C. Therefore, even when the control signal C is not transmitted, a solar battery 26 of a secondary side unit 20 photodetects the offset part at all the time. Thus, by controlling the value of this offset part, the secondary side unit 20 can receive sufficient power from the primary side unit 10.

Filed: 1981-11-27
Abstract: PURPOSE:To suppress a rush current, by flowing a charging current of a capacitor through a current limit element, through the opening of a switching element with the detection of power failure and the closing of the switching element after a prescribed set time at the restoration of the power failure. CONSTITUTION:A switching signal which goes to a low level at the detection of power failure and again goes to a high level with a delay after the restoration of the power supply, is outputted from a delay circuit 13 with a power supply detection signal. A switching device 14 is opened for a prescribed time through this switching signal, a trigger voltage applied to a gate of a thyristor 4 is lost and the thyristor 4 is opened for a prescribed time. Then, since a rush current flows through a current limit resistor 3, the rush current peak can be suppressed, allowing to prevent damages to circuit components and failure on the reception system.
