Title: Manufacture of oxide superconductive wire material
Inventor: FUKUSHIMA SHIN
IPC: C01G1/00
Filed: 1987-05-19
Abstract: PURPOSE:To make it possible to produce an oxide superconductive wire material easily by covering a sintered body or single crystals consisting of elements which compose the oxide superconductor with a metallic material, and giving a wire drawing process. CONSTITUTION:After the component elements of an oxide superconductor are mixed sufficiently, they are baked temporarily and powdered to get an oxide superconductor powder. The resultant powder after such a process is made in a desired form and sintered. By giving a specific sintering condition, crystal particles grow up to make single crystals. A coverage of a metallic material is given to the sintered body or the single crystal material gained in such a way, and a wire drawing is carried out to get a desired form. After this wire drawing process, it is heat-treated in an ambiance including oxygen. In this case, as the oxide superconductor, a perovskite structure oxide superconductor including a rare earth element of a high critical temperature is used. And as the metallic material, Ag or an Ag alloy mainly of Ag is used.

Title: Discriminating circuit for presence of record information
Inventor: FUJINAGA TADAHISA
IPC: G11B15/087
Filed: 1984-06-12
Abstract: PURPOSE:To obtain a discriminating circuit which is suited to integration by using a detection circuit that obtains an output signal when the level of an AC signal sent from a reproduction head exceeds the level of the offset voltage set at an input terminal. CONSTITUTION:The synthetic signal of right and left channels is produced by resistances 16A and 16B and led to an input terminal 32 of a detection circuit 31 via a coupling capacitor 17. The terminal 32 is connected to a differential amplifier DA having an offset. Transistors TRQ1 and Q2 and a constant current source I1 are provided to the amplifier DA, and the offset voltage is set so that the base potential of the TRQ1 exceeds the base potential of the TRQ1 in an initial state. When a signal having a level higher than the offset voltage level is produced at the terminal 32, the base current of a TRQ7 flows. Then the TRs Q8 and Q9 are turned on to give a decision output showing the presence of signals to a monitor control circuit 35. The input sensitivity is changed with the signal sent from a terminal 33. Thus it is possible to obtain a discriminating circuit which is suited to integration.

Title: Liquid ejection recording device
Inventor: KAMURAGI YOSHIAKI
IPC: B41J11/00
Filed: 1988-05-19
Abstract: PURPOSE:To set a heating temperature which allows liquid droplets for recording to be fixed optimally and minimize the deformation and discoloration of recording paper by providing a heating temperature control means which changes the temperature of the heating temperature. CONSTITUTION:If a heater temperature-setting command is transferred from a host device 20, and a heater temperature is set at a high temperature T1, a heater 11 which heats recording paper 9 is controlled at the constant temperature T1. In addition, if a heater setting temperature is set at a low temperature T2 by a heater temperature selector switch, the surface temperature of the heater 11 is maintained at the temperature T2. Consequently, it is possible to set a heating temperature at which liquid droplets for recording are fixed to the recording paper in an optimum state in accordance with the difference in the fixing property of the recording paper, or ambient environments. Furthermore, it is possible to limit the deformation and discoloration of the recording paper by a heating means to a minimum extent under a simple constitution and at low cost.

IPC: H01L21/306
Filed: 1978-09-30
Abstract: PURPOSE: To preforate a hole at an insulating film while preventing overetching of the film by disponsing pair electrodes oppositely to conductive metal under the insulating film in an etching liquid and applying voltage between the electrodes to restrict the electrodes from reacting.  
     CONSTITUTION: Resist 9 is coated on the portion except for a hole of an insulating film, and one end of a lead wire 11 is connected to an aluminum wire 4 exposed at 8. A platinum electrode 13 is disposed oppositely in a tank 16 filled with etching liquid 15. The insulating film 7 is etched by applying voltage between the wire 4 and the electrode 13 using NH 4 F etching liquid. This etching liqude etches nonporous alumina layer 6, but since negative bias voltage is applied to the wire 4, the aluminum is prevented from ionizing to stop etching when the alumimun wire 4 is exposed. When negative bias is applied to the wire 4, the insulating film can be etched accurately and exactly without apprehension of overetching to thereby perforate the film.

Abstract: PURPOSE:To smoothly accumulate paper sheets, by controlling a telescopic opening member arranged in the inner bottom part of an accumulating section into which paper sheets having their front and rear surfaces put in order are selectively introduced, so that the introduction side of the paper sheets comes to be upside. CONSTITUTION:Paper sheets having their front or rear side judged, are conveyed downstream into the introduction part 11a of a paper sheet accumulating section 11. A gate 13 is set in accordance with the result of judgment by an upstream judging section. For example, if the paper sheets face at the front side, the gate is set as shown by the solid line to distribute the paper sheets onto a first conveying path 12a. Meanwhile if the paper sheets face at the rear side, the gate is set as shown by the chain line to distribute the paper sheets onto a second conveying path 12b. When sensors 14a, 14b which are provided intermediate of the paths 12a, 12b, respectively, detect the passage of each paper sheet, telescopic opening members 16a, 16b formed in the inner bottom section of an accumulating section 15 are driven to make the introduction side of the paper sheet face upward. When the judged paper sheets are accumulated, the opening members 16a, 16b are opened downward to allow the paper sheets to drop onto a carrier 17. With this arrangement it is possible to smoothly accumulate the paper sheets.

Abstract: PURPOSE:To form a sharp image on the image formation surface of an image pickup means and to facilitate angle control over the image pickup means about an object to be measured by arranging an interference filter between the image formation surface of the image pickup means and an image forming lens group which is constituted in retrofocus structure. CONSTITUTION:A measurement unit 2 is equipped with an irradiation means 3 and the image pickup means 4. The irradiation means 3 shapes the light from a laser light source into slit light L, which is projected on the measured surface of an object 1 to be measured. The image pickup means 4 picks up the projection image drawn on the measured surface of the object 1 with the slit light L and converts the image into the quantity of light, which is outputted. Then the image forming lens group 10 of the image pickup means 4 is constituted in the retrofocus structure and the interference filter 20 is arranged between the image formation surface 20 of the image pickup means 4 and the image forming lens group 10. Consequently, even if the angle of incidence of the slit light L on the object 1 of measurement from the projection image deviates, the light comes to nearly parallel light by the retrofocusing of the image forming lens group 10 and the whole of the single-wavelength light which is incident on the image forming lens group 10 passes through the interference filter 30.
