Title: Method and apparatus for producing ultra-quickly cooled thin amorphous alloy strip
Inventor: TANJI YASUNORI
IPC: B22D11/06
Filed: 1985-09-12
Abstract: PURPOSE:To improve quality by providing a heat resistant plate having many holes right above a molten metal ejection nozzle, inserting a carbon ring thereunder and heating the carbon ring with a high-frequency furnace. CONSTITUTION:The heat resistant plate 8 having the many holes is disposed as a furnace material in a molten metal supply pipe 1 and the carbon ring 11 is inserted as a getter material to the under side thereof so as not to contact directly with a molten metal 2' and the pipe 1. A raw material metal is charged onto the plate 8 and while gaseous Ar is introduced into the pipe 1 from the upper part thereof, the metal is heated together with the ring 11 with the high- frequency heating furnace 4. After the raw material melts, the pipe 1 is lowered to exert pressure to the molten metal 2', thereby ejecting the metal from the nozzle. The ring 11 acts as the getter material in this stage to prevent the formation of an oxide film on the metal 2'. The ejection of the molten metal 2' is thereby stabilized and the quality is improved.

Title: Towing type booster
Inventor: MORIMOTO HIDEYUKI
IPC: F16D25/12
Filed: 1982-11-15
Abstract: PURPOSE:To improve the responsiveness of operation by forming a projection capable of being contacted with a body at an input member. CONSTITUTION:Since a valve member 33 is seated on both valve seats 31, 32 at nonoperation time, the member 33 and the valve seat 31 are separated immediately in response to the leftward movement of an input member 21 to introduce atmospheric air. Accordingly, no reactive stroke exists. Since the valve seat 32 and the valve member 33 are separated by the operation of a valve spring 30 when returning from the operation state to the nonoperation state even if the valve seat 31 and the valve member 33 are seated, no differential pressure is generated to move a movable unit 14 to both pressure chambers 15, 16. Since a stopper member 75 is engaged with the input member 21 and a threaded part 74 is formed relatively long in length, the position of a stopper member 75 can be readily controlled, and can be accurately adjusted without influence of the error of the components.

Title: Elrhardt pipe making method
Inventor: DOHARA TADASHI
IPC: B21C23/20
Filed: 1990-07-26
Abstract: PURPOSE:To produce a hollow blank pipe having excellent inside surface quality by previously determining the temp. range where the hot workability between an outside layer part and a central part is good and heating a working blank material in such a manner that the outside layer part and central part respectively attain the above-mentioned temp. range of the good hot workability in piercing. CONSTITUTION:The temp. range where the hot workability of the outside layer part and central part of the working blank material is improved is previously determined. This temp. range is determined by investigating the dependency of the hot workability on temp. by a high-temp. tension test. The temp. range where the hot workability of the outside layer part and central part is improved is previously determined with each steel kind of the working blank materials. The working blank material is heated in a heating furnace kept at the set in-furnace temp. above the temp. at which the hot workability in the central part of the blank material is improved. The blank material is ejected from the furnace when the central part of the billet attains the temp. at which the above-mentioned hot workability is improved. The hollow blank pipe having the excellent inside surface quality free from transverse crack flaws is produced in such a manner even from the working blank material consisting of a high-alloy steel.

Title: Dry etching device
Inventor: FUJII TERU
IPC: H01L21/302
Filed: 1983-10-28
Abstract: PURPOSE:To markedly improve the power of etching treatment by contriving the speed-up of etching under low pressures and at low power by a method wherein rims surrounding electrodes disposed in an array are provided with a plurality of magnetic field generation means at the position of symmetry between the respective electrodes. CONSTITUTION:A plasma 6 is generated between the upper and lower electrodes 2 and 3 by a high frequency power source 5; at the same time, conduction to electromagnetic coils 21A and 21B by means of electric wires 22A and 22B produces ring-like magnetic lines of force around the coils, which then form a cusped magnetic field 25 or a mirror magnetic field 26 at the center surrounded by these magnetic lines of force. The plasma generated by the magnetic field 25 or 26 is narrowed, and the phenomenon of diffusion of its electrons due to the thermal motion is restrained; thus, the collision density with the etching gas is increased, and ionization can be promoted. The plasma electrons are accelerated by the generation of the electric fields, causing cyclotron motion and drift motion. The probability of collision with the etching gas is increased by marked elongation of the flying distance of the charged particles of the plasma; accordingly, ionization is promoted.

IPC: G01J1/44
Filed: 1985-09-10
Abstract: PURPOSE:To detect the balance point of the quantity of incident light at a high speed with high sensitivity by impressing reverse bias voltages to the 1st and the 2nd photodiodes respectively. CONSTITUTION:The 1st photodiode 1 has the 1st cathode connected to the 1st voltage, e.g. a positive potential +Vn and the 1st anode connected to the 2nd cathode of the 2nd photodiode 2, whose 2nd anode is connected to the 2nd voltage lower than the 1st voltage, e.g. a negative potential -VB. When the 1st incident light and the 2nd incident light to the 1st and the 2nd photodiodes 1 and 2 are equal in quantity, there is no difference between the 1st and the 2nd photocurrents generated by the incident light beams and no current, therefore, flows through a load resistance 3, so that the output voltage is zero. In this case, this circuit impresses the reverse bias voltages to the 1st and the 2nd photodiodes 1 and 2 to detect the balance point of the quantity of incident light at a high speed with high sensitivity.

Title: Read circuit for magnetic disk device
Inventor: NAKAMURA AKIRA
IPC: G11B5/09
Filed: 1989-08-03
Abstract: PURPOSE:To decrease the capacitance of a capacitor for DC offset by inputting a readout voltage signal to an input of an emitter follower and biasing the input of the emitter follower via a resistor whose resistance is high. CONSTITUTION:A DC offset of a readout voltage signal amplified by an amplifier 10 is eliminated by a built-in capacitor 16. The readout voltage signal with the DC offset eliminated therefrom is inputted to a base of a transistor (TR) 18 of an emitter follower. Moreover, a bias voltage to operate the TR 18 is fed to the base via a resistor 20. Then the combined impedance imp of the circuit is a parallel impedance between the resistance of the resistor 20 and the input impedance of the emitter follower, and a resistor whose resistance is high is employed for the resistor 20 and a constant current source 24 is connected to the emitter of the TR 18 of the emitter follower to obtain a high parallel impedance. Thus, the capacitance of the capacitor 16 to eliminate the DC offset is enough to be small.

Filed: 1987-08-13
Abstract: PURPOSE:To prevent the breaking of a semiconductor element and the adverse influence on a liquid crystal by mating plural substrates and packaging the semiconductor element to at least a sheet of the substrates by local heating and soldering. CONSTITUTION:The semiconductor element 13 having solder bumps 14, 15 is mounted onto the wiring patterns 11, 12 of the glass substrate 100 after the liquid crystal 20 is injected between the substrates. The light projected from a light source 1 is quadrisected by an elliptical reflecting mirror 2, 1st mirrors 3, 4, 2nd mirrors 5, 6 and cylindrical lenses 7, 8. These light rays project the connecting pints of the bumps and wiring patterns from the rear face of the glass substrate 10. Since the glass substrate 10 is transparent, the light rays transmit through the substrate and the wiring patterns 11, 12 are locally heated. The solder is melted by this heat, by which the solar bumps 14, 15, the wiring patterns 11, 12 as well as the many connecting points are respectively simultaneously connected. The breaking of the semiconductor element by static electricity, etc., and the adverse influence of the flux of the solder on the quality of the liquid crystal display are thereby prevented.
