Title: Preparation of thin membrane
Inventor: AOKI TAKAO
IPC: B29L7/00
Filed: 1985-09-03
Abstract: PURPOSE:To make thin membrane formation possible without any decrease in such physical properties as separation characteristics and soon which the raw material should possess, by containing a polymer having a hydrophilic group in the first solution consisting of a solution of a membrane-forming raw material as main component in an organic solvent. CONSTITUTION:A solvent, which can homogeneously dissolve a membrane- forming raw material, has low surface tension, and has an appropriate volatility by which desolvation can easily occur from the thin membrane when extended on water surface,is used as the first solution. The first solution contains a polymer having a hydrophilic group. As this polymer having a hydrophilic group, an oil soluble organic polymer containing carboxyl, amino, hydroxyl or ammonium group as a hydrophilic group can be used. As the spreading speed of the polymer solution increases by containing a polymer having a hydrophilic group in the polymer solution and the membrane formation is rapidly performed, a membrane can be prepared with high speed. When attempting wider membrane formation, it can be easily achieved with less numbers of feeding nozzles as the spread area of the polymer solution increases.

Abstract: PURPOSE:To shorten the compiling time by performing a process for excluding the strings of statements in the range sandwiched between a 1st and a 2nd sequential execution specified statements as a sequential execution block from an object of parallelization. CONSTITUTION:A parallelism extraction part 14 performs a process for extracting parallelism for the specific block in a source program 10. At this time, a sequential execution interpretation part 13 detects and interprets the 1st specific sequential execution specification statement in the source program 10 as the start of the sequential execution block, and then detects the 2nd specific sequential execution specification statement pairing with the 1st sequential execution specification statement and extracts the part from the 1st specific sequential execution specification statement to the 2nd specific sequential execution specification statement as the sequential execution block. Then the parallelism extraction part 14 performs the process so that a parallelizing process is performed not for the sequential execution block, but only for blocks other than the sequential execution block. Consequently, the compiling time is shortened.

IPC: B24B19/00
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a polishing film for a photo connector having good sticking property to a polishing pad, being easily detachable and materualizing stable polish. SOLUTION: Thus polishing film is formed with a polishing layer 2 on the surface of a supporting body 1 and a slippage prevention layer 3 on the back of the supporting body 1, while the slippage prevention layer is composed of a minute sticking thin layer of 2 to 4 μm thickness. At least the surface of the supporting body 1 formed with the slippage prevention layer 3 has an uneveness of a center line average surface roughness Ra75 within the range of 0.1 to 1.0 μm formed thereon. Therefore bubble is not produced between the polishing pad and a polishing film when it is fixed, fixing and separation can be easily performed, and adhesive does not remain on it after separating it. Also highly accurate polishing can be accomplished because, at the time of polishing, the slippage prevention layer is of thickness not effecting the pressure applied to a material being polished.

Filed: 1993-08-06
Abstract: PURPOSE:To provide a closed type environment control system capable of being reduced in occupying volume within closed type environment and capable of effectively utilizing tools and materials. CONSTITUTION:Carbon dioxide discharged from the person or animal 1 in closed type environment is removed and concentrated by a CO2 removing and concentrating device 2 and a part of carbon dioxide is supplied to a plant 7 to generate oxygen which is, in turn, returned to the person or animal 1. The remainder of removed carbon dioxide is decomposed into methane and water in a first reaction furnace 3 and water is decomposed into oxygen and hydrogen by electrolysis while oxygen is returned to the person or animal 1. Methane is sent to a second reaction furnace 8 packed with a catalyst wherein an iron catalyst is supported on a heat-resistant carrier to be decomposed into carbon and hydrogen. Obtained carbon is burnt in a carbon dioxide regeneration device 9 if necessary to be supplied to the plant 7 as carbon dioxide. Since the second reaction furnace 8 is packed with the iron catalyst, heat of reaction may be low and the reaction furnace 8 is miniaturized. During a period when carbon dioxide supplied to the plant 7 may be little, carbon in the system is stored in a solid state.
