Title: Infrared sensor and infrared camera including the same
Inventor: YAMAGA EIZO
IPC: H01L31/18
Filed: 1988-03-24
Abstract: PURPOSE:To obtain photoelectric sensibility effective to infrared rays up to a longer wavelength by using the mixed-crystal p-type Si1-xGex of P-type Si and Ge as a semiconductor. CONSTITUTION:An infrared sensor employs a metal-semiconductor rectifying contact, and a p-type Si1-xGex mixed crystal is used as a semiconductor. That is, the mixed-crystal thin-film of Si and Ge is epitaxial-grown onto an Si substrate in a Schottky junction, and the wavelength of infrared rays having effective photoelectric sensibility is made longer than that of a conventional Pt-P-type Si Schottky junction by utilizing the reduction of forbidden band width due to the mixing of Ge and the decrease of the height of the trouble of the Schottky junction with the reduction of forbidden band width. Accordingly, the height of trouble determining the threshold wavelength of photoelectric sensibility to infrared rays is further lowered, thus acquiring the infrared sensor having photoelectric sensibility effective up to a longer wavelength.

Title: Manufacture of laminated sheet
Inventor: KISHIDA YOSHIJI
IPC: B29C47/56
Filed: 1978-06-14
Abstract: PURPOSE: To obtain a laminated sheet having a sufficient adhesivity as a meat packaging tray without using an adhesive, separable and recoverable, by laminating a styrene resin on a polyolefin in the same die.  
     CONSTITUTION: A resin composition comprising 100 parts by wt. of polystyrene and at least 5 parts by wt. of a styrene-butadiene block copolymer is extrusion laminated on polyethylene or an ethylene-olefin random copolymer in the same die. Preferably, the block copolymer comprises 10W70 wt.% of butadiene from the standpoint of transparency and its amount is at least 5 parts by wt. per 100 parts by wt. of the postyrene due to the adhesivity and impact resistance. Low-density polyethylene or ethylene-propylene random copolymer resin is preferred as the polyolefin because of slight deterioration of transparency in molding with hot plates.

Title: High performance alloy, its production and use
Inventor: OKADA OSAMU
IPC: C22C38/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy having excellent high temp. strength, corrosion resistance and suppressing the damage of the material caused by the irradiation of neutrons in a high irradiating environment by forming the structure of mother phases of equiaxed crystals and a dendritic structure dendritically grown into equiaxed crystals. SOLUTION: For securing the strength at high temps. of the alloy, its structure is regulated to equiaxed crystals 1 suppressing sliding motion and a dendritic fine mixed structure 2 dendritically grown into equiaxed crystals. Furthermore, in this equiaxed/dendritically fine mixed structure, the surface area of the boundaries increases compared to that of an equiaxed grain structure having the same gain size, and since the segregation of impurities and the formation of pitting corrosion are suppressed, its corrosion resistance improves. For producing the alloy having this structure, it is preferable that a discharge plasma sintering method in which powder is used as the raw material and its instantaneous sintering by high temp. plasma is made possible is used.  For obtaining the above alloy on a nanoscale having the above mixed structure, Attoritor or the like is used, mechanical grinding for applying intensive working to the powder is executed, and thereafter, the discharge plasma sintering method is performed to form a sintered body.

Title: Oxide superconductor and metal covered wire using the same
Inventor: NOMURA KATSUMI
IPC: C04B35/45
Filed: 1989-03-23
Abstract: PURPOSE:To enhance supeconductivity of bulk material or a wire by subjecting a mixture powder, which has undergone a heat treatment at a medium temp. zone below the sintering temp. either prior or subsequent to mixing, to the heat treatment for sintering. CONSTITUTION:Crude powder prior to mixing or a powder as starting material to processing is provisionally baked at a medium temp. zone of 400-800 deg.C which lies below the sintering temp. That is, a 500-600 deg.C heat treatment for several thru 24hr subsequent to the drying process will completely decompose the liquid medium attached to the powder and having remained into CO2+H2O. Because the heat treatment temp. and time depend on the properties of the crude powder and starting material and the conditions of storage, etc., determination of these values is made upon conducting thermal analyses, fixation of crystal phase, qualitative and quantitative analyses of elements. Use of this starting material, which is of uniform quality and active in chemical terms, should enhance the characteristics as bulk material or a wire.

IPC: C23C14/24
Filed: 1995-03-29
Abstract: PURPOSE: To produce a vacuum vapor deposited and galvanized steel strip which is free from mottled patterns on the surfaces by regulating the temp. of a steel strip just before winding the steel strip around a winding roll heated at its front surface to the evaporation temp. of zinc or above at the time of winding the steel strip around the winding roll and depositing zinc vapor thereof by evaporation while the steel strip is made to travel around the roll. CONSTITUTION: The steel strip 14 which is a material to be plated is annealed in a reduction annealing furnace 2 and is transported via a soaking duct 3 to a cooler 4 where the temp. of the steel strip 14 is adjusted. The steel strip is then transported to a first vacuum vapor deposition chamber 9 where the steel strip is made to travel while the steel strip is wound around the first winding roll 6 heated to about 500 deg.C. The zinc vapor is then vacuum deposited by evaporation on the one surface of the steel strip 14. Further, the steel strip is transported into a second vacuum vapor deposition chamber 10 where the steel strip made to travel while the steel strip is wound around the second winding roll 7 heated to about 500 deg.C. The zinc vapor is then vacuum deposited by evaporation on another surface of the steel strip 14 and thereafter, the steel strip is transported to a temper rolling mill 13. The temp. of the steel strip just before the winding rolls 6, 7 is set in the temp. range of 250 to 300 deg.C or 150 to 200 deg.C in the operation. The formation of the mottled patterns on the surfaces of the vacuum vapor deposited and galvanized steel strip is thus prevented.
