Title: Humidifying device
Inventor: KUWAZAWA HIROYASU
IPC: F24F6/10
Filed: 1989-02-14
Abstract: PURPOSE:To effect humidification, to prevent adhesion of fur, and to facilitate maintenance management by a method wherein atomized water is brought into contact with a vaporizing surface the temperature of which is maintained at a value higher then the vaporizing temperature of water, and film boiling is produced on a vaporizing surface. CONSTITUTION:A humidifying device brings water atomized through a nozzle 2 into contact with a vaporizing surface 1 the temperature of which is maintained at a value approximately 50 deg.C higher than the vaporizing temperature of water, causes film boiling of water atomized on the vaporizing surface 1 to gasify it, and performs humidification by means of steam. The vaporizing surface 1 is formed as the one surface of a metallic plate 2a, and an electric heater 3 is embedded in the metallic plate 2a. A specified amount of water is fed from a water tank 4 with the aid of a self-suction type pump 5, water discharged through the nozzle 2 produces fine particles with a grain size of 50-100mum, a part of the fine particles flows on the air flow of a blower 6, a part thereof flows to the vaporizing surface 1 for immediate gasification, and is discharged as humidifying air togetherwith the air flow of the blower 6. Since a time in which a moisture content resides on the vaporizing surface 1 is reduced to almost zero, calcium chloride and magnesium chloride, contained in water, are prevented from being deposited and adhered as fur, and maintenance management is also facilitated.

Title: Detector of corona discharge
Inventor: YAMASHITA TAKAHIRO
IPC: G01R31/08
Filed: 1989-02-13
Abstract: PURPOSE:To search for a position where a corona discharge is caused in an equipment in the operative state by providing a detecting coil which detects a very weak electromagnetic wave due to said corona discharge and generates a signal current proportional to a discharge current. CONSTITUTION:When a corona discharge detector 20 is brought close to an object 6 to be detected, if a very weak electromagnetic wave is generated as a result of a corona discharge, a detecting coil 2 generates a signal current proportional to a current of the corona discharge. When the signal current is output from the detecting coil 2, the signal current is amplified to a predetermined level by an amplifier 3 and converted to a photo signal by an electro- photo converter 4. The photo signal is converted to an electric signal by a photoelectric converter 7 which in turn outputs the signal to a gate circuit 8. The signal from the gate circuit 8 is a signal resulting from removal of noise components so that only a signal as a result of the corona discharge necessary for measurement is output to a CPU 10. The CPU 10 processes the data of the signal in a suitable manner to be displayed by a CRT 13 or printed out by a printer 14. Accordingly, the position of the corona discharge can be searched.

IPC: B60T8/26
Filed: 1978-03-27
Abstract: PURPOSE: To compensate for the decrease in a braking force due to a trouble in one hydraulic brake circuit, by providing a hydraulic pressure control valve device among conduits of a multi-circuit hydraulic brake and by raising hydraulic pressure supplied to a normal rear wheel brake when said hydraulic brake circuit is defective.  
     CONSTITUTION: The hydraulic pressure control valve device 100 is provided among the conduits 13, 14, 19, 20 of a first and a second hydraulic brake circuits to control hydraulic pressure supplied to rear wheel brakes 16, 22 of the brake circuits. When the fist hydraulic brake circuit is defective, the pressure in a second inlet port 40 and a passage 38 becomes almost zero and a piston 37 moves rightward. At that time, the volume of a hydraulic chamber 36 on the left end of the piston 37 increases and the leftward force of a spring 39 vanishes. Thus, the hydraulic pressure supplied to the normal rear wheel brake becomes higher than usual to compensate for the decrease in the braking force due to the trouble.

Title: Liquid crystal display device
Inventor: HOSHINO MINORU
IPC: G02F1/133
Filed: 1992-02-21
Abstract: PURPOSE:To reduce in-surface brightness unevenness by decreasing a difference depending upon the position of the waveform distortion of a voltage generated under the influence of the impedance of a picture element. CONSTITUTION:A liquid crystal panel 11 is constituted by crossing and arranging plural signal electrodes Xm and plural scanning electrodes Yn across a liquid crystal layer and forming picture elements in matrix, and when a signal voltage and a scanning voltage whose waveforms vary stepwise are applied to one-end sides of the signal electrodes Xm and scanning electrodes Yn of the liquid crystal panel 11 to drive the liquid crystal of the respective picture elements, the waveform of at least one of the scanning voltage and signal voltage applied to the respective electrodes is distorted by a constant quantity. Consequently, the waveform of the liquid crystal driving voltage applied to each of the picture elements in a display area is already distorted. Consequently, the influence of input part resistance and impedance of each picture element is made a little, so variation in the distortion of the voltage waveforms is reduced and the difference in driving voltage effective value due to a difference in picture element position is made small, so the brightness unevenness is reducible.
