Title: Building plate for clean room and manufacture thereof
Inventor: TAKAMI YUKINORI
IPC: B32B27/18
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To make the atmosphere of a clean room non-electrostatic by disposing a paint layer of specified thickness on the surface of a foam vinyl chloride resin plate with a specific expansion ratio using conductive powder compounded solvent type vinyl resin paint. SOLUTION: A conductive powder compounded resin paint layer 1 is disposed on the surface of a foam vinyl chloride resin plate 2 with closed cells or open cells with a skin layer, and an expansion ratio is set to 2-10 times. Conductive powder compounded resin paint is applied to the surface of the foam vinyl chloride resin plate 2 so that the film thickness of the resin paint layer 1 is 1-8μm, and dried by heating at 40 deg.C or lower. Conductive powder compounded solvent type vinyl resin paint is used as the conductive powder compounded resin paint. A solvent is formed of a mixture of a high boiling point solvent and a low boiling point solvent, and methyl ethyl ketone is used for the low boiling point solvent.  Excellent separation resistance of vinyl resin and vinyl chloride resin is therefore obtained, and a non-electrostatic state in a room is stabilized for a long period of time so as to prevent electrostatic trouble at the time of manufacturing semiconductor IC chips.

Title: Method and equipment for syntax structure signal analysis
Inventor: EDOUARUDOUSU JIYOSEFUSU UIRIBU
IPC: G06F17/27
Filed: 1994-02-10
Abstract: PURPOSE: To realize efficient execution by allocating a violation score to a syntax analysis result based on the unification of a feature group. CONSTITUTION: An input signal S is supplied to a conversion unit 101 and the signal S is converted into a primitive mark string P, a normalized primitive mark string L and the feature group at the current time. A syntax analysis unit 102 reads the mark string and collates whether a part which is read follows grammar stored in a memory 103 or not. When it follows grammar, the analysis result A is generated by the syntax analysis unit 102. When the regulated feature violates grammar by means of collation, the syntax analysis unit 102 increases the violation score and the analysis result is detected with the violation score. The analysis result is processed again with the original signal S, the primitive mark string P and the mark string L which is made into phrases.
