Title: Gap wafer cleaning method and cleaning fluid used for the method
Inventor: MATSUMOTO HIROSHI
IPC: C11D7/26
Filed: 1993-12-10
Abstract: PURPOSE:To remove metal Ga or the like adhering to a GaP wafer without etching the crystal surface of the GaP wafer by a method wherein cleaning fluid composed of hydrochloric acid and acetic acid mixed at a certain mixing ratio by volume is used. CONSTITUTION:Cleaning fluid composed of hydrochloric acid and acetic acid was changed in the mixing ratio by volume of hydrochloric acid to acetic acid to check the change of the Ga content dissolved into cleaning fluid. The metal Ga content dissolved into cleaning fluid was small when the mixing ratio by volume of hydrochloric acid to acetic acid was 1:0.1 or below or 1:0.8 or above. Therefore, cleaning fluid composed of hydrochloric acid and acetic acid mixed at the mixing ratio 1:0.1 to 0.8 is used. It is found by a check that this mixed cleaning fluid is restrained from etching the crystal surface of a GaP wafer. By this setup, metal Ga or the like adhering to a GaP wafer can be removed without etching the crystal surface of the wafer.

Title: Seed chuck for pulling up crystal
Inventor: NAKAZAWA HIRONOBU
IPC: C30B15/32
Filed: 1990-11-15
Abstract: PURPOSE:To allow the pulling up of a crystal having a large weight by providing heat radiating fins on the seed chuck for pulling up a crystal to be connected to the pulling up means via a ball chain. CONSTITUTION:The plural heat radiating fins 6 are projectingly formed on the side face of the circular cylindrical body part 2 of the seed chuck 1 having the body part 2, an approximately cylindrical ball chain connecting part 3 and an approximately cylindrical seed crystal mounting part 4. The fins 6 are preferably formed of metallic Mo having a high thermal conductivity. The heat radiating area is increased in this way and the quantity of the heat radiation to the circumference increases as compared to the case of the absence of the heat radiating fins and, therefore, the quantity of the heat transferring from the seed chuck 1 to the ball chain 10 decreases. The deterioration of the ball chain 10 by the heat is substantially prevented in this way and the possibility that the ball chain 10 breaks is eliminated even when the large crystal ingot is pulled up.

Title: Production of thermoplastic polyester resin foamed sheet
Inventor: KUMAGAI TATSUO
IPC: B29C48/32
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To make surface beautiful and to lower a degree of crystallization by holding the surface temp. of a foamed sheet to specific temp. or lower during the period immediately after extrusion to the molding of the sheet by a mandrel. SOLUTION: The surface temp. of a thermoplastic polyester resin foamed sheet is held to 180 deg.C or higher until the sheet reaches the mandrel from an extruder.

Abstract: PURPOSE:To make it possible to store logged information efficiently by compressing data, then storing the compressed data before storage of the logged information, and decoding the data and reading the decoded data when reading the data. CONSTITUTION:When compressing logged information such as error before writing said information into an external storage device 14 from CPU 11, CPU 11 checks whether or not an error has occurred. If CPU 11 interpretes that the error has occurred, it issues a command to a compression circuit 12 so that a character code for information to be logged is compressed. The compression circuit 12 compresses a single record of data based on the command and then stores the compressed data in the external storage device. Next, CPU 11 reads compressed information such as error from the external storage device 14 and issues a command for decoding to a decoding circuit 13. In turn, the decoding circuit 13 reads a single record of error information from the external recording device 14 and decodes the information. Finally, the circuit 13 transfers the decoded error information to CPU 11.
