Title: Cooling device for projecton television
Inventor: MITANI KATSUAKI
IPC: H01J7/26
Filed: 1987-11-30
Abstract: PURPOSE:To maintain the performance against the temperature drift, make a device lightweight and small-sized, and reduce the cost by using a mixed liquid of ethylene glycol and diethylene glycol as a cooling liquid filled in a liquid-tight space. CONSTITUTION:A liquid-tight space 9 is formed with a projection tube 1, a spacer 2, a radiator 3 and a lens 4, and a cooling liquid 9a is filled to cool the projection tube 1. A mixed liquid of ethylene glycol and diethylene glycol is used as the cooling liquid 9a. This cooling liquid has little permeation loss quantity, the vapor pressure is low, the inner pressure of the space 9 is low, thus the cooling liquid 9a can be brought into direct contact with the lens 4. The deterioration in lens performance due to the temperature drift dose not occur, a liquid with the refraction factor approximate to that of the lens 4 can be generated, the contrast is improved. The device is thereby made lightweight and small-sized, and the cost can be reduced.

Title: Storage method for radioactive gas
Inventor: TAKANO YOSOKO
IPC: G21F9/02
Filed: 1987-11-30
Abstract: PURPOSE:To assure the secure adhesiveness between an implanting and accumulating layer and electrode surface by previously generating sputtering to an outside cathode to clean the inside surface of the outside cathode as a pretreatment for implantation and storage of a radioactive gas. CONSTITUTION:The flow of gaseous Kr to extract and discharge the gas is executed simultaneously with the start of an ion implantation operation and a negative voltage is impressed to the inside cathode 6 and the outside cathode 1, respectively. This negative voltage is about 0--100V on the cathode 6 and about -1,000V on the cathode 1. The voltage on the cathode 6 is set measurably lower than the voltage on the cathode 1. Gaseous ions 12 ionized by electric discharge are strongly attracted to the cathode 1. The gaseous ions 12 are accelerated toward the cathode 1 until finally the ions induce the sputtering on the inside surface of the cathode 1. The impurities such as oxide films on the inside surface of the cathode 1 are removed and adequate roughness of the atom size is generated by this sputtering. The adhesiveness between the gas implanting and accumulating layer 1 and the inside surface of the cathode 1 is thereby improved and since the gas discharge is stably continued, the smooth gas implantation is assured.

Title: Apparatus and method for reducing noise and distortion
Inventor: TOOMASU EMU GUREEFU
IPC: H03F1/32
Filed: 1993-12-03
Abstract: PURPOSE: To reduce the noise and distortion of a sound signal. CONSTITUTION: The input sound signal is equally divided and distributed to a couple of voltage and control amplifiers(VCA). Each VCA receives an equally divided sound signal current and its gain is controlled with a common control voltage. The outputs of the respective VCAs are put together and applied to the inverted input terminal of an operational amplifier IC2. The gain of each VCA is set to 6 dB and the gain of the operational amplifier is set to -6 dB. The operational amplifier adds the sound signals together at 6 dB and also adds noise and wide-band signals together at 3 dB, so the S/N of the output signal increases to reduce total higher harmonic distortion and cross-modulation distortion.
