IPC: C01B23/00
Filed: 1993-09-28
Abstract: PURPOSE:To permit the transfer of liquefied crude rare gas in a rare gas cooling tower into a gas bomb while restraining the evaporation of the same. CONSTITUTION:Crude rare gas in which oxygen remains after a rare gas cryogenic separation process is deoxidized in a rare gas thickening tower 7 to thicken it to obtain the crude rare gas of (Kr+Xe  about 99%).

Title: Manufacture of semiconductor device having light transmission window
Inventor: HASHIMOTO TOMOAKI
IPC: H01L21/56
Filed: 1989-09-19
Abstract: PURPOSE:To manufacture a semiconductor device which protects a light receiving area properly and is provided with a light transmission window by evacuating a hollow section which is formed of a transparent material and resin so that it has a specified vacuum pressure and resin-sealing a specified region under a state where the transparent material is adhered to a resin wall. CONSTITUTION:An element where a chip 1 is installed to a die pad 5 is provided and transferred to a specified position in a chamber 11 and mounted thereon. On the other hand, glass 4 is transferred into the chamber 11 and supported by a hand. An evacuation 15 is performed to obtain a specified vacuum degree by means of an evacuation device which is connected with an exhaust port 13. A thrust jig 14 comes into contact with the upper surface of the glass 4 and to a halt under a slightly thrusting condition, which eliminates a clearance 16 formed between the glass 4 and the resin wall 3 since the resin wall 3 is made of silicon and flexible. Therefore, the glass 4 and resin wall 3 are placed in very close contact with each other. Then, the thrusting jig 14 is adapted to rise so that it may be released from the glass 4. At that time, a hollow section is under a vacuum state while the outside is under an atmospheric pressure. Therefore, the differential pressure thrusts the glass 4 against the resin wall 3 and thereby seals the gap with a resin sealing process.

Abstract: PURPOSE:To correctly demodulate transmitted data without being influenced by time difference due to a clock signal by varying and setting detecting time for detecting the peak value of a main lobe appearing at a definite period by a correlation signal obtained by correlation between a DS signal and the same diffusion code as a transmitting side. CONSTITUTION:After every data d0 to dN-1 stored in a shift register 1 is multiplied successively by the same diffusion codes P0 to PN-1 as the transmitting side by a multiplier 2, it is summed successively by a first adder 3, and the correlation signal Vo equivalent to a base band signal is outputted from this first adder 3.
