Title: Production of composite hollow yarn membrane
Inventor: AOKI TAKAO
IPC: B01D69/08
Filed: 1986-08-07
Abstract: PURPOSE:To continuously obtain a fluid separation membrane with less infiltration into a porous hollow yarn and having excellent permeability by supplying a soln. of a membrane forming material in an org. solvent over the surface of a liq. incompatible with the soln. to form a thin layer, and bringing the thin layer into contact with the hollow yarn. CONSTITUTION:An optional polymer capable of forming a substantially non- porous film by a casting method can be exemplified as the membrane forming material. The material is dissolved in a solvent having a positive expansion coefficient, capable of uniformly dissolving the material, and having appropriate volatility. The concn. is preferably controlled to <=10wt%. The membrane material soln. 5 is supplied over a solvent 6 incompatible with the soln., forming a distinct interface, not dissolving the membrane material, and having high surface tension. The membrane material soln. is spread, and a thin layer is formed. The hollow yarn 8 is continuously supplied into the thin layer and brought into contact with the layer. Consequently, the infiltration of the active layer material into the porous hollow yarn is reduced, and a separation membrane having excellent permeability can be continuously obtained.

Abstract: PURPOSE:To surely and simply detect gas-leakage from a mechanical seal, by providing a trap chamber in the mechanical seal on the side opposite to a chamber in which gas flows, so that leak gas is trapped in this trap chamber and is led to a gas detector after being separated from oil. CONSTITUTION:A mechanical seal 8 seals between a turbin casing body 1 and a turbine shaft 2 and between front and rear bearing boxes 18, 19. That is, the mechanical seal 8 prevents the inflow of gas at a slide surface 66 by pressing a stationary ring 42 and a loose ring 41 against the slide surface 66 with the use of hydraulic pressure supply from an oil pump 15. In this stage, if the loose ring 41 is damaged so that gas flows in through the slide surface 66, this gas enters through a gap 5 into a trap chamber 50 where oil is separated from the gas, and then is transferred to a gad detector 62 through a trapping lne 60. Accordingly, the gas detector 62 is operated to indicate gas leakage.

Title: High-quality character printing
Inventor: YOSHIDA MASAYUKI
IPC: G09G5/24
Filed: 1988-07-25
Abstract: PURPOSE:To prevent printing speed decrease and also output high-quality characters by storing high-quality dot pattern data in ROM for frequently used characters or characters with significantly deteriorated quality, and using 48-dot pattern data for other than the afore-mentioned characters. CONSTITUTION:In order to prevent the decrease of display and printing speeds to a maximum possible extent, characters with low use frequency are for instance, stored in ROM in a 48-dot pattern. In addition, Chinese characters consisting of many straight lines are stored in ROM in a 48-dot pattern because the quality does not deteriorate if extended. Frequently used characters such as HIRAKANA or KATAKANA or characters with the quality which deteriorates if extended are stored in ROM in a high-quality dot pattern. Thus the use efficiency of ROM is maximized and characters can be displayed or printed in a high-quality state without the reduction of display or printing speed.
