Title: Temperature gradient heating furnace and manufacture of oxide super-conductor
Inventor: OGAWA NAOYUKI
IPC: H05B3/00
Filed: 1993-02-05
Abstract: PURPOSE:To obtain a heating furnace in which a material for an oxide superconductor is heated and a temperature gradient from one end toward the opposite side is properly given to the material regardless of the thickness of the material by providing a cooling device on the furnace bed to cool the end of the material. CONSTITUTION:A heating furnace 11 is surrounded with heating device 10 and a material 12 for an oxide super-conductor, etc., is placed on a furnace bed 13 in the furnace 11. A liquid or gas cooling medium 14 flows through the inside of the furnace bed 13, so that the material 12 is cooled from below and given a temperature gradient. Therefore, after an oxide super-conductor molding material is heated and melted, a slow-cooling step in which the molding material is slowly cooled drown with an one-way temperature gradient maintained is effectively carried out.

Title: Optical recording medium
Inventor: SAWAMURA MITSUHARU
IPC: G11B7/2534
Filed: 1983-02-09
Abstract: PURPOSE:To obtain a satisfactory reflection preventing effect by forming successively a resin layer, a reflection peventing film containing plural layers of films having internal stresses opposite to each other and a recording layer on an optical recording medium and a substrate, respectively. CONSTITUTION:A reflection preventing film contains a ZnS film having the compression stress as a film of a high refractive index and an MgF2 film or an Na3 AlF6 film having the tensile stress as a low refractive index film. An adiabatic layer 2 of organic resin is formed on a glass substrate 1a. Then a film 3a having the compression stress, a film 3b having the tensile stress and a film 3c having the compression stress are formed by the vacuum vapor deposition method for the reflection prevnenting film. In addition, a recording magnetic layer 4 and a protecting film 5 are provided to be bonded to a glass substrate 1b via an adhesive layer 6. Thus an optical recording medium is obtained. The reflection preventing layer contains reflection preventing layers 3a and 3c as the films having high refractive indexes and a reflection preventing film 3b as a film having a low refractive index respectively. In such a constitution, the film cracks can be prevented when a reflection preventing film is formed with a resin substrate or a resin layer on the substrate used as a foundation layer.

Title: Manufacturing method of thermoelectric material
Inventor: ENDO ISAO
IPC: H01L35/34
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To sinter a thermoelectric material even in the atmosphere by hot pressing raw material metal powder at pressure of a specific value or higher. SOLUTION: Raw material powder is pressurized and sintered with hot press. The hot press is performed with the conditions of pressure of 1000kg/cm<2> or more. The sintering with the hot press is desired to be performed at higher pressure within a range where no trouble is caused for the strength of a metal mold, etc. More specifically, the pressure of 2000kg/cm<2> or higher is more desirous, and 3000kg/cm<2> or higher is further more desirous.  The raw material powder being relatively small in its diameter is oxidized when it makes contact with the atmosphere and hence allows an oxide film to be formed on a powder surface, but large pressure of 1000kg/cm<2> or higher is applied to the raw material powder upon sintering with the hot press so that the oxide film on the powder surface is destroyed at a stretch and a sintered product not substantially affected by the oxide film is formed. Accordingly, there is no need of the use of expensive atmospheric gas such as Ar gas, and hence the running cost is reduced.

Filed: 1983-02-10
Abstract: PURPOSE:To compensate for influence of stray field by providing an adder/amplifier for lapping a signal to be obtained through detection of outer stray field over a scanning circuit signal while regulating the addition/amplification gain in accordance to the output of beam fluctuation to be produced from detected secondary electronic signal. CONSTITUTION:Electron beam 2 produced from an electron gun 1 is focused through an electronic lens 3 then scanned by a deflecting unit 4. A secondary electron detector 7 will detect secondary electron 6 and the detected secondary electron signal is fed through an amplifier 8 to a picture image memory 9. The accumulated signals are processed through a picture image processor 10 to produce the amplitude of beam fluctuation which is set in a gain regulator 11. A search coil 12 arranged around a chamber 18 or a mirror tube 19 will detect the outer field and feed to the amplifier 13. The gain of amplifier 13 is determined in accordance to the output from the regulator 11. The amplified signal is applied through an integrating circuit 14 to an adder 16 and lapped over the scanning signal to drive a deflector 4. Consequently influence of stray field can be compensated.

Abstract: PURPOSE:To improve the elasticity of an FPC while the FPC is maintained in a highly flexible state by making the thickness of an insulating film, especially, coating film of a polyimide resin nearly equal to that of a base film only at a part requiring elasticity.

Filed: 1988-01-29
Abstract: PURPOSE:To easily control the reference voltage from outside with high accuracy by using a switching circuit and a capacitor in place of a resistor group and a switch group of a conventional circuit and controlling the repeating frequency of a clock. CONSTITUTION:The input voltage 1 is supplied to an operational amplifier and the repeating frequency of a clock having a cycle T is given to the semiconductor switches 4 and 5. Then the electric charge of a capacitor 6 (capacity C) is controlled by the difference of potential between nodes (a) and (b) for decision of the reference voltage 3(VR). The switches 4 and 5 serve as the MOSTRs having the channels of the same polarity and are turned on and off alternately and repetitively in the cycle T. Thus the electric charge of the capacitor 6 is controlled by means of the difference of potential between the nodes (a) and (b). In such a way, an equivalent resistance 10 is obtained. The resistance value R2 of the resistance 10 is decided as R2=T/C. Thus it is possible to control the value VR of the voltage 3 from outside by controlling the cycle of the clock applied to the switches 4 and 5.

Filed: 1988-01-31
Abstract: PURPOSE:To vary resolution optionally and to improve the resolution easily by using a polygon mirror and using a spot of a laser beam on an original. CONSTITUTION:A laser beam radiated from a laser diode 2 is collimated by a collimater lens 4, reflected in a reflecting face of the polygon mirror 5 and the image is formed as a spot of the laser beam on the original 50 via an ftheta lens 6. Since the polygon mirror 5 deflects periodically the laser beam while being driven at a high speed, the laser beam spot is scanned linearly on the original face. Thus, the irregular reflection light of the laser beam spot is read during scanning independently of the position. Thus, the resolution is improved easily.

Title: Surface combustion burner
Inventor: YAHAGI MASAHIRO
IPC: F23D14/16
Filed: 1993-02-08
Abstract: PURPOSE:To obtain a stable and dilute combustion with a high load and to control the lift of a flame and a combustion resonance sound by providing elongated clearances in the form of rectangular parallelopiped with a prescribed dimension in a porous member constituting the combustion surface of a surface combustion burner. CONSTITUTION:A surface combustion burner is assembled in such a manner that a plurality of porous veneers 11 in the form of rctangular parallelopiped are arranged with clearances 12 of 0.5 to 2.0m/m held, second thin and porous veneers 13 with the same width are disposed on four peripheral edges of the porous member thus obtained and fixed thereon by screws and the porous member 1 is mounted on a casing. The premixed gas passing resistance (pressure loss) of the porous member 1 is the highest in the four peripheral edges in which porous materials are laminated. The parts made of the porous veneers 11 are lower in pressure loss than the peripheral edges and higher than the parts of clearances 12. Thus, upon the dilute combustion with a high load, the premixed Gas passes the four peripheral edge parts, and a generated flame serves as a flame holding function so that the lift of the flame is prevented from being generated. Since a flame in the elongated clearances 12 is long and stable, the generation of a combustion resonance sound can be suppressed.
