Title: Manufacture of high purity fine molded item
Inventor: YANAGISAWA ISAO
IPC: B28B21/42
Filed: 1990-11-29
Abstract: PURPOSE:To separate easily a molded item from a graphite base by a method wherein a graphite member which is obtd. by mixing a graphite with a binder and sintering the mixture is extrusion-molded to obtain a fine graphite base and a molded item is vapor-deposited thereon by means of chem. vapor deposition. CONSTITUTION:A graphite powder is mixed with a ceramic binder and an org. thermoplastic resin or an org. thermosetting resin as binders and the mixture is sintered to prepare a graphite member, which is then extrusion-molded to obtain a graphite base which is a fine product, e.g. a rod-like product with a diameter of 3mm or smaller. A molded item such as PBN is vapor-deposited thereon by means of chem. vapour deposition. Formation of the molded item is done by means of chem. vapour deposition, which is usually performed at a higher temp. than 1,450 deg.C and as this graphite base is a mixture of a ceramic binder and a synthetic resin, the graphite base is softened at this temp. and separation of this molded item from the graphite base is easily performed. In addition, as the binder, alumina (Al2O3) and polyvinyl chloride etc., can be cited.

IPC: G11B7/005
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To perform tracking servo control in the way of 3 beams and also to electrically reduce cross talk based on a signal read out by the same 3 beams. SOLUTION: Parts deviated from an objective read-out track by 1/4 track pitch from the centers of individual adjacent tracks are irradiated by an optical pickup 4 with its two sub-beams respectively under the state of its main beam irradiating the objective track. The tracking servo control is performed by a tracking servo circuit part 6 with a difference of each of read-out signals E-RF and F-RF of the individual sub-beams as an error signal respectively. In a cross talk eliminating circuit part 9, a cross talk component signal is generated by adjusting the read-out signals E-RF and F-RF of the individual sub-beams in frequency characteristic and amplitude, and the generated cross talk component signal is subtracted from a main read-out signal M-RF to obtain the main read-out signal 9a with reduced cross talk.

Title: Printing control device, printing device, printing control method, printing method, and recording medium
Inventor: RIYUU SATSU
IPC: B41J2/125
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To print a high quality image without lowering the printing speed as much as possible in the case a nozzle failure is generated. SOLUTION: Nozzle rows are recognized preliminarily as an assembly of continuous three or more blocks including nozzles of the same number. In the case a nozzle failure is generated, a block failure position including the nozzle failure is recognized. Moreover, in the case the block failure is generated, a compensation operation for compensating the black failure by another block is stored, corresponding to the block failure position. In the case a block failure is recognized, an image is printed while executing the compensation operation stored corresponding to the block failure position. Since an image can be printed while executing an adequate compensation operation according to the nozzle failure generated position thereby, a high quality image can be printed without much lowering the printing speed even in the case a nozzle failure is generated.

Title: Manufacture of semiconductor laser
Inventor: UCHIDA SHIRO
IPC: H01S5/00
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To mass-produce a semiconductor laser in which protective films are formed on the end faces of resonators by housing bar-like semiconductors in the recessed sections of a substrate and forming protective films on the exposed side faces of the semiconductors by vapor growth. SOLUTION: A semiconductor laser LD is formed by cleaving a bar-like semiconductor 13 along the planes indicated by the chain lines b1 , b2 , b3 ,... between each ridge 9 and forming protective films 14 on the end faces of semiconductor chips faced to the end faces of resonators which become light emitting end face of the laser LD. Since the protective films 14 can be formed by the MOCVD method by using the same material as that used for, for example, the clad layers 2 and 4 of the semiconductor laser LD having a band gap larger than that of an active layer 3, the absorption of emitted laser light by the protective films 14 can be avoided effectively. Therefore, the semiconductor laser LD can be mass-produced, because the protective films 14 can be formed while the bar-like semiconductors 13 constituting the semiconductor laser LD are maintained as they are.
