Title: Rotary compressor
Inventor: ISAKA SHINICHI
IPC: F04C18/30
Filed: 1986-03-13
Abstract: PURPOSE:To obtain a rotary compressor capable of treating liquid and gas- liquid-mixed fluid by providing a pressure regulating mechanism which releases fluid to the outside when the internal pressure in the fluid passage in the course of compression of a rotor exceeds a prescribed pressure. CONSTITUTION:On the groove bottom part of the rotor body 23 of a rotor 4 consisting of a rotor body 23 and a rotor shaft, an auxiliary discharge port 8 is formed, and to this auxiliary discharge port 8, a valve 9 which is always energized in the closing direction via a spring 10 is brought into contact. Since the auxiliary discharge port 8 is so constituted that when the valve 9 opens, it communicates with the discharge passage 3 via a space 12 provided in the rotor body 23 and a space 13 provided in the rotor shaft, even if liquid compression takes place in the compression space, there is no fear of damage in any of the compressor members. Consequently, it follows that, even in the case where liquid or gas-liquid-mixed fluid is treated, the rotary compressor can be enabled to be safely used.

Abstract: PURPOSE: To control the purity of crude Ar, overhead product, within a spedified value all the  time by controlling the operation of crude Ar tower by measuring constantly the purity of Ar at a  point of the crude Ar tower where the Ar purity is greatly changed.   
     CONSTITUTION: The feed gas from the side cut stage of the rectifier's upper tower 7 is supplied  to the crude Ar tower 11, directed to go up the tower 11, and then heat-exchanged with liquid air  charged through the overhead condenser 26 to liquefy the gas. The liquefied descending liquid is  subject to a vapor-liquid contact at the tray 27 for rectifying separation, where crude Ar gas of a  98% purity, for example, is drawn out of the overhead as crude Ar gas product and also a crude  Ar liquid product is drawn out of the tray 29 several stage lower than the overhead tray. On the  other hand, a O 2 -rich liquid is extracted from the lower part of the tower 11 and then sent back to  the lower part 28 of the tower 7. The purity of the crude Ar gas product and the crude Ar liquid  product is measured at each point of the lines 25 and 29, and also a mixed fluid of Ar, O 2 , and N 2   is extracted from the medium of the tower 11 tray where the Ar purity is greatly changed to  measure the purity of Ar. And, the Ar purity and N 2  in feed gas are measured at a point where the line 21 is branched at the side cut stage, and also the purity of return liquid from the tower 11  is measured at a point of the line 22.

Title: Production of sic-si3n4 based powder
Inventor: KODAMA NOBUHIRO
IPC: C01B21/068
Filed: 1986-03-13
Abstract: PURPOSE:To improve the rate of reaction and make it possible to industrially and advantageously produce the titled powder, by reacting a mixed green compact of an amorphous nitrogen-containing silane compound with carbon while changing the pressure in the reaction process. CONSTITUTION:A powder mixture of an amorphous nitrogen-containing silane compound, preferably Si2N3H with carbon, preferably fine carbon black powder at 0.1-0.5 atomic ratio (C/Si) is put in a graphite crucible and reacted while heating. In the process, the mixture is kept under reduced pressure, e.g. <=5mmHg, up to 1,000-1,200 deg.C in order to promote thermal decomposition of the Si2N3H and prevent oxidation by oxygen. The reaction system is then hermetically sealed while kept under reduced pressure in order to prevent formation of free Si which is a by-product and promote the reaction for forming SiC and Si3N4. The reaction is carried out at 1,350-1,450 deg.C for 1-3hr. Thereby the rate of reaction can be improved to produce the titled powder at a relatively low temperature.

IPC: H04N5/335
Filed: 1981-04-10
Abstract: PURPOSE:To reduce the defects of an image by performing blooming control and increasing charge transferring ability larger than the quantity of accumulated charge of received light so as to transfer the normal quantity of charge for each picture element completely. CONSTITUTION:In each channel range 21, the areas of an accumulation part ST (ST1, ST2) on a stage are formed so as to be larger than the areas of a transfer part TR (TR1, TR2) and a channel stop range 23 is formed between the range 21 and an overflow drain range 22. At the accumulation of received light, charge is mainly accumulated to the side of the transfer part TR by controlling the voltage applied to a transfer gate electrode and the quantity of accumulated charge is controlled by the voltage of the gate electrode. Excessive charge is absorbed into the range 22. Since the area of the accumulation part is larger than that of the transfer part, the charge transferring ability is larger than the quantity of accumulated charge of received light, transferring the charge completely. Thus, blooming control and the reduction of defective images can be performed by the said simple configuration.
