Title: Iron slide part of compressor, its surface treatment method and compressor
Inventor: IIZUKA TADASHI
IPC: F04C29/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve resistance against wear of a compressor which is compact, provides high output, and has high performance by forming a slide face consisting of an oxygen nitrided layer and a multiporous oxidized iron film of which main component is triiron tetroxide sequentially on a surface of a base in an iron slide part which constitutes a compression mechanism which compresses refrigerant fluid. SOLUTION: In a compressor in which a compression mechanism which compresses refrigerant fluid is formed by a plurality of opposing iron slide parts and refrigerating machine oil is supplied to a slide part of the slide parts when liquid is compressed, either or both of slide faces of the iron slide parts are treated by oxygen nitriding in a mixture gas containing 0.5 to 5% of air in ammonia gas at 450 deg. to 650 deg.C, and then an oxygen nitrided layer 22 in which particlelike nitride iron and oxidized iron coexist is formed on a surface of a base 24. Next, steam treatment is done at 400 deg. to 800 deg.C to inflate oxidized iron so that a multiporous oxidized iron film 21 of which main component is triiorn tetroxide and has a thickness of 0.1 to 10μm is formed on a top layer of the oxygen nitrided layer 22.  Consequently, it is possible to improve the burning property and the adhesion property between slide members.

Title: Bar code reader
Inventor: URATA HARUSHIGE
IPC: G06K7/015
Filed: 1992-12-25
Abstract: PURPOSE:To obtain a bar code reader which is capable of surely reading bar code information by providing an area sensor where a photoelectric conversion is performed for the reflection light from a bar code label and an area sensor scanning circuit scanning this in an arbitrary direction. CONSTITUTION:The reflection light of a bar code label A or B irradiated from a light source 11 is image-formed in an area sensor 13 to be converged in a condensing lens. When the bar code label is in an arbitrary direction the scanning direction of the area sensor 13 is made to coincide with the image-forming direction of the bar code label by the area sensor scanning circuit 16. Next, after a photoelectric conversion into an electric signal. is performed for the reflection light of the labels A, B by the sensor 13, it is amplified by an amplifier circuit 14 and is outputted to a decoder 15. Subsequently, it is converted into character data and is outputted. Thus, bar code information is surely read because the scanning direction of the sensor 13 is properly changed to the direction of the bar codes A, B by the sensor scanning circuit 16 even if the labels A, B are in any direction.
