Abstract: PURPOSE:To suppress the quantity of wear so as to improve the durability of a compressor by forming a vane and a roller of an alloy obtained by mixing or more one kinds of ceramics grain selected out of tungsten carbide, titanium carbide, and like, in a matrix alloy with cobalt as a main component. CONSTITUTION:In a compressor using refrigerant 1,1,1,2-tetrafluoro-ethane (R134a), not containing chlorine in a molecule, as compressed gas for a problem such as the destruction of an ozone layer, a roller 6 rotatably supported at the eccentric part of the shaft 2 of a motor is accommodated in a cylinder with a vane 7 integrated therein. In this case, the vane 7 and the roller 6 are formed of a cobalt group alloy formed by mixing one kind or more of ceramics grain, selected out of tungsten carbide, titanium carbide, titanium nitride, vanadium carbide, chromium carbide, silicon carbide and silicon nitride, in a matrix alloy with cobalt as a main component. The coagulant wear of the vane 7 and roller 6 is thereby prevented, and the durability of the compressor is improved.

Title: Method for counting particulates contained in sample gas
Inventor: KIMURA MASAO
IPC: G01N15/06
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for counting particulates contained in the sample gas which can correctly count the particulates. SOLUTION: In order to achieve the calibration, the sample gas from a source 41 is allowed to flow in a bypass pipe 44, size-controlled particulates are given thereto by a porous member 27, and the saturated steam from a source 51 is mixed therein. The saturated steam is condensed with the size- controlled particulates as cores by passing the fluid through a condenser 53 for cooling. The temperature of the condenser 53 is set so that the detection limit of a counter 53 corresponds to the size of the dimension-controlled particulates. Next, to achieve the actual measurement, the sample gas from the source 41 is allowed to flow through a main pipe 43, the saturated steam is mixed therein to form the fluid for measurement, and the particulates contained in the sample gas are counted using the temperature-set condenser 53 and counter 53.

Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for recognizing character with which operability/ processability is improved by extracting the same type of character strings from recognized candidates. SOLUTION: While successively fetching candidate character groups provided from character recognition, a same type character string segmenting part 3 segments cursive form of Japanese syllabary (KANA)/square form of KANA type character strings.

At such a time, a marker is added to the character matched with the word dictionary 7. AKANA/Chinese character (KANJI) converting part 4 performs KANA/KANJI conversion to the character string having no marker and adds the result to the candidate character group. Besides, the segmenting part 3 segments the KANJI/alphanumeral type character strings from the candidate character groups, these character strings are compared with the previously set dictionary 7 by the word matching part 6, the coincident character strings are extracted, and these character strings are exchanged with the recognized result of 1st candidate in the candidate character group. At such a time, a marker is added to a fixed word part.
