Title: Fixing pin for ceramics sheet and fixing method using it
Inventor: FUKUDA MASAAKI
IPC: B23K11/00
Filed: 1985-07-31
Abstract: PURPOSE:To fix a ceramics sheet to a metallic plate easily by inserting the fixing pin having a projection body at the tip into the fitting aperture of the ceramics sheet which is placed on a metallic plate and by welding with electrification the fixing pin and metallic plate with pressing the fixing pin to the metallic plate. CONSTITUTION:A fixing pin P1 is inserted into the fitting aperture 3 of the ceramics sheet 1 arranged on a metallic plate 2. A big current is instantaneously passed between the fixing pin P1 and metallic plate 2 under the condition of the fixing pin P1 being pressed to the metallic plate 2. The vicinity of the projection T1 having bigger electric resistance becomes in high temp. with heating. The projection T1 melts the abutting part of the metallic plate 2 and the projection T1 itself melts. The fixing pin P1 is therefore deposited on the metallic plate 2 and the taper face S of the fixing pin P1 comes in contact with the inner taper wall face of the fitting aperture 3. Consequently the ceramic sheet 1 is easily fixed to the metallic plate 2.

Abstract: PURPOSE: To prevent accidents during reuse that occur when a user forgets turning a power switch off by starting a timer device at the same time that the power switch is turned on, and causing a solenoid to be driven by the stopping action of the timer switch so as to turn the power switch off. CONSTITUTION: A timer device 19 is actuated at the same time that the ON button 1 of a power switch 18 is operated, and drives a solenoid 11 at the same time as stopping action that occurs when the time set by the timer has elapsed. When a predetermined timer limit is set and the ON button 1 is pressed, a sliding plate 13 moves resisting the energizing force of a coil spring 17, an engaging projection 4 is engaged with a notched part 14, and contacts 9, 10 are closed by an insulator 8. After the time set by the timer has elapsed the solenoid 11 is driven at the same time by the stopping action of the timer. The solenoid 11 attracts the sliding plate 13, and the ON button where the notched part 14 is disengaged from the engaging projection 4 is restored to its initial position to turn the power switch 18 off.  Therefore the attracting force of the solenoid 11 is turned off and the sliding plate 13 is restored to its initial position by the force of the spring.

Title: Manufacture of superconductor
Inventor: SUGAHARA KAZUYUKI
IPC: H01L39/06
Filed: 1987-07-08
Abstract: PURPOSE:To simplify or omit the etching step of a superconductive thin film, by forming a film, which does not transmit oxygen, on a superconductive material in a region, where a superconductor is not required, and forming a superconductor by the projection of heating light in a gaseous atmosphere including oxygen with said film as a mask. CONSTITUTION:An oxide film 6 and a nitride film 7 are formed on a superconductive material 4 in an amorphous state by photoengraving and etching methods. The films are formed in a region other than a region, wherein a superconductor is used as a wiring. A substrate is heated to 500 deg.C. Argon laser light having a wavelength of 5,145 Angstrom is projected in an atmosphere including oxygen. The superconductive material 4 is heated to 850-1,000 deg.C, when the Iaser light is projected, and crystallized. Since the substrate is heated to 500 deg.C, the oxygen in the atmosphere osmoses into the sintered superconductive material 4 in the region, where the oxygen film 6 and the nitride film 7 are not provided. Thus the material 4 is transformed into a superconductor 41 having the composition of YBa2Cu3O7. Since the nitride film 7 blocks the osmoses of the oxygen into the superconductive material 4, a material 42, whose composition lacks the oxygen, is formed in the region, where the oxide film 6 and the nitride film 7 are present.

Title: Combustion method of emulsion oil
Inventor: ASAKAWA YUUKICHI
IPC: F23C99/00
Filed: 1983-09-19
Abstract: PURPOSE:To speed up the combustion of emulsion oil, by making the same burn within a space to which an electric field is bestowed. CONSTITUTION:A plate 1 made of aluminum prepared is grounded. A dotted electrode 2 is provided at a position 40mm. above the plate 1 and AC voltage of 50Hz is applied to a space between the position and the ground through a transformer 3. A period of time until combustion is completed has been measured by putting 10g of emulsion oil to be made by adding water to light oil so that moisture content becomes 20% within the plate 1. When oil is made to burn without applying the voltage to the electrode 2, though the light oil burns in 120sec, 305sec are necessary in case of the emulsion oil. Even if, however, it is the emulsion oil the voltage of 3.0kV is applied to the electrode 2. It is burnt in 96sec. In addition to the above, when the voltage is raised, combustion period of time is shortened all the more and when the voltage of 15kV is applied, the combustion period of time is reduced to 44sec, that is, 37% of that available at the time of nonapplication of the voltage to the light oil and 14% of that available at the time of nonapplication of the voltage to the emulsion oil.

Title: Magnet type reducing valve
Inventor: ARIIZUMI RYOZO
IPC: G05D16/06
Filed: 1994-07-22
Abstract: PURPOSE:To provide a reducing valve, where the force acting upon the diaphragm body is not so changed and the flow rate characteristic is not degraded even at the time of the change of the diaphragm body, by providing one of the diaphragm main body and a relatively moving member with a magnet and providing the other with a magnetic member which causes magnetic attraction in the same direction as the energizing direction of a spring means. CONSTITUTION:A second magnet body 31 facing a first magnet body 21 is fixed to a lower housing 11b. A diaphragm main body 24 is moved and energized toward the lower housing 11b by a compression spring 35. In this constitution, the spring constant of the compression spring 35 is made apparently small because the magnetic attraction of first and second magnet bodies 21 and 31 is applied to the compression spring 35. That is, first and second magnet bodies 21 and 31 approach each other simultaneously with expansion of the compression spring 35, and the change of the force applied to the diaphragm main body 24 is reduced because the attraction is increased in inverse proportion to the aquare of the distance. Thus, the degree of opening of an open/close valve 16 is higher than a conventional example, and the flow rate is increased.

Title: Input mechanism of optical tracking device
Inventor: ARAI NOBUKATSU
IPC: G02B23/00
Filed: 1979-12-27
Abstract: PURPOSE: To enable the tracking of target objects from high to low speeds to be performed smoothly and accurately by providing an input mechanism which generates the driving power signal in proportion to the movement of man's hand to an optical tracking device which tracks the target object.  
     CONSTITUTION: The right handle 4b, shaft B9, shaft C12, shaft D13, and knob 14 of the optical tracking device are supported by a bearing 19, and are so constituted that, if the right handle 4b is operated, the shaft B9 revolves to revolve a synchronizing signal transmitter, thereby moving a elevation prism 2. If gears of a large number of teeth are employed for the shaft B9 side of the gear train G 2  and those of a small number of teeth for the shaft C12 side, the revolution of the knob 14 will be faster than the revolution of the synchronizing signal transmitter 10. Hence, the elevation prism is rotated at a high speed and a low speed, respectively, by rotating the right handle 4b when the target object is of a high speed, and the knob 14 when it is of a low speed, whereby the tracking is accomplished smoothly and accurately.
