Title: Formation of metal silicide
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/28
Filed: 1981-02-12
Abstract: PURPOSE:To obtain the metal silicide layer of uniform quality having no effect in the atmosphere of heat treatment by a method wherein the required metal layer, which will be eutectically alloyed with an Si region, is formed on the Si region, or a metal silicide layer is attached on the Si region using CVD method, and a heat treatment is performed while the above is covered by an SiO2 film using CVD. CONSTITUTION:A film 2 such as Ta and the like, with which a eutectic alloy will be formed with Si, is coated in the approximate thickness of 1,000Angstrom  on the surface of a single crystal Si substrate 1, and an SiO2 film 3 of 1-2mum in thickness is grown on the film 2 using the CVD method. Then, after a heat treatment has been performed in ordinary N2 gas atmosphere at the temperature range of 700-1,000 deg.C for thirty minutes, the film 3 is removed by exfoliation. Thus, Ta and Si are reacted with each other and a Ta-Si layer is formed on the surface  of the substrate 1, but as the SiO2 film is grown by a low temperature plasma,  the Ta is not degenerated, and also it is not oxidized when a heat treatment is  performed, thereby enabling to obtain the eutectic alloy with a perfect mirror  face. As for the metal, W, Mo, Pt and the like may be used as the metal besides Ta.

Title: Method and device for regeneration of molding sand
Inventor: NAGANO SHIGEFUMI
IPC: B22C5/08
Filed: 1980-02-18
Abstract: PURPOSE: To effectively utilize combustion calorie of combustibles in molding sand and surely  prevent their sticking on the inside wall surfaces of a furnace by allowing the molding sand,  which is supplied at a constant rate into a rotary furnace, to burn of itself and suppressing the  combustion temp. thereof by the exhausting of the center part in the furnace.   
     CONSTITUTION: While the molding sand (a) to be regenerated is being supplied 3 continuously at  a constant rate from one end of a rotary furnace 1 to the other end side, it is heated up to 750W 800°C by a burner 5 from the other end of the furnace 1. A suitable amount of air contg. O 2  is  introduced 10 during said procedure, and when the sand (a) begins to burn at above 650°C, the  temperatures of the sand (a) and the furnace inside rise. Following this procedure, the max. temp. shifts gradually to the molding sand supply port 2 side, and the temp. is elevated from the molding sand take-out port 4 up to the center part. Thence, the combustion of the burner 5 is gradually throttled until it is stopped finally, so that the combustibles contained in the sand (a) are  allowed to burn of themselves. Since the temp. in the furnace is elevated further by this self-combustion, the damper 16 of a combustion gas exhaust part 12 for controlling heating temp. is  opened to exhaust the high-temp. combustion gas from the approximate center part of the furnace  1 directly to the outside to keep the temp. in the furnace ≤800°C.

Filed: 1985-02-04
Abstract: PURPOSE:To provide an information recording medium which permits stable recording without forming bits, consists of a single-layered recording film and has excellent resistance to oxidation by sputtering an In target by the plasma of a gaseous mixture composed of at least methane hydrocarbon and oxygen on a substrate thereby forming the recording film. CONSTITUTION:The recording film 12 manufactured by sputtering the In target by the plasma of the gaseous mixture composed of the methane hydrocarbon and oxygen is deposited on the substrate 11. For example bubbles (build-up deformed parts) 13 formed by the irradation of the laser beam which is pulse- modulated according to the information to be recorded are provided on the film 12. The irradiated laser beam for reproduction is diffracted according to the shape of the bubbles 13 in the region where the bubbles 13 are formed and therefore the intensity of the reflected or transmitted light is considerably different from the intensity of said light in the region (flat part) where the bubbles 13 are not formed. The satisfactory reproduction of good CNR is thus made possible by detecting the intensity of the reflected or transmitted light and taking out the reproduced output corresponding to the presence or absence of the bubbles 13.

Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To restrain degradation of an emitting surface due to electron emission and to extend the service life by moving a photo-cathode orthogonally to an optical axis of an excited light during electron emission. SOLUTION: A photo-cathode 1 is connected with a motor 9 at a rotation axis 8, and rotates at a rotation speed ω during electron emission. The rotation axis 8 is kept in parallel with an optical axis 13 within ±1 deg.. The rotation speed ω is determined almost from degradation speed D (1/hour) and rotation radius (distance between the rotation axis 8 and the optical axis 13) R, current variation can be restrained small when it is used at ω>>D/R. When it is used near ω=D/R, the life expires exactly at one rotation. Light radiation amount per unit area can be reduced, and the life is about 4 R/r times longer than that when the photo-cathode is not moved. Therefore, when convergence light is a spot of 780 nm wavelength and r=1 μm, the life is 40000 times longer at R=2 cm.
