Abstract: PURPOSE:To prevent occurrence of a crack by forming a vacuum evaporated glass layer composed of SiO2, Na2O, Al2O3, B2O3, etc., on the surface of a glass blank. CONSTITUTION:A core glass 101 is set to a dome 203 for film formation and placed in a vacuum tank 201. The vacuum tank is evacuated through an evacuation opening 205 and the core glass 101 is heated by a heater 202 to a prescribed temperature.

Title: Rotary compressor
Inventor: KITAYAMA HIROSHI
IPC: F25B1/04
Filed: 1981-12-02
Abstract: PURPOSE:To prevent the overheated refrigerant gas from flowing into the evaporator by shutting out the overheated gas, which flows out to the condenser and suction line from the compressor, while the compressor is at a standstill. CONSTITUTION:When the shaft 6 stops, the inflow line 19 formed in the cylinder 5 in No.2 discharge valve device 18 is put out of communication with the discharge hole 24 provided in the valve element 26 and, also, out of communication with the outflow line 21 leading to the discharge pipe 20. Thus No.2 discharge valve device 18 is closed. Accordingly the overheated gas while the compressor is at a standstill is prevented from flowing into the evaporator through the condenser of the refrigerating system, and thus temp. rise in the evaporator is prevented. Thereby any solenoid operated valve as in a conventional system is no more necessary as well as the power consumption can be reduced, and further risk of leakage at welds when a valve element is separately installed in the refrigerating circuit can be suppressed to assure a raised reliability.

Title: Biosensor and operation thereof
Inventor: TAKEYA MAKOTO
IPC: G01N33/543
Filed: 1988-08-03
Abstract: PURPOSE:To analyze and detect an antigen at a high sensitivity and handily by detecting that a structural change occurs in an antibody to break an antibody orientation membrane when the antigen is bonded to the antibody orientation membrane. CONSTITUTION:An antibody orientation membrane 2 is supported with a support 1 and an object to be measured is introduced into an air introduction tube 3. The orientation membrane 2 is so thin as to be broken easily when a structural change of an antibody molecule occurs by an antigen-antibody reaction. The breakage of the orientation membrane 2 is detected with a light source 4 and a photo detector 5 and can be observed easily by an optical method. In addition, as the orientation membrane 2 is small in capacity, the antigen- antibody reaction occurs even when the concentration of a component to be detected is low in the membrane. Moreover, the orientation membrane 2 can be taken out and prepared after support 1 with a tiny hole is dipped into an aqueous solution of the antibody. This enables highly sensitive analysis and detection of an organic compound in air handily without using a complicated trapping/concentration means and reaction system.

Abstract: PURPOSE:To obtain high resolution by forming a structural part supporting a magnetic detection part and a signal processing circuit and adjusting its inclination so that a sensor pattern is arranged on a position directly opposed to the magnetic pole of a magnetic recording rotary body. CONSTITUTION:The structural part 9 supporting the magnetic recording rotary part 1, the magnetic detection part 2 and the signal processing circuit 3, plural screws 10-14, a lead wire 6 and a structural part 4 supporting the whole system are formed and covered with a sheath 5. The structural part 9 is fixed on the structural part 4 by the screw 10. Azimuth and the ununiformity of a gap are adjusted by the screws 11-14. Since the structural part 9 is inclined in an optional direction by clamping the screws 11, 12 or 13, 14, the ununiformity of the gap in the axial direction can be corrected. Consequently, the sensor pattern of the magnetic detection part 2 can be arranged on a position directly opposed to the magnetic pole of the magnetic recording rotary part 1, so that high resolution is obtained.

However, the power supply is not supplied to the buffer circuit 9, load circuit 10 and the power interruption sensing circuit 13 due to a presence of a reverse current preventive diode 5 and then a transistor 12 is turned OFF. When the transistor 12 is turned off, a load for the back-up capacitor 8 which is apt to flow through A B or A C is prevented from being flowed and then the back-up time is extended.

At the time of bonding the board 3 to the board 4, in addition, the occurrence of such a state that the solder balls 2 are crushed and protrude from the board pads 8 is avoided by supporting the board 3 by the surface mount jig 1 from four sides. Therefore, the intermediate board 3 can be easily arranged on a prescribed position of the mother board 4 by means of the jig 1.

Title: Tablet
Inventor: NAGAYAMA TADAHIRO
IPC: G06F3/045
Filed: 1982-11-08
Abstract: PURPOSE:To produce a miniature tablet for handwritten patterns by setting a pressure-sensitive and conductive rubber sheet between two sheets containing electrodes formed at two counter sides of the resistance sheets having uniform surface resistance so that the sides of the electrodes are orthogonal to each other. CONSTITUTION:When a non-conduction state between resistance sheets 11 and 12 changes to a conduction state at a point 30 the voltage change generated at output terminals 31-34 of amplifiers 22-25 is proportional to the currents flowing to lead wires 18-21. Therefore both horizontal and vertical coordinates are obtained from the ratio of voltage change between terminals 31 and 32 and between terminals 33 and 34 respectively. Then the offset voltage of amplifiers 24 and 25 is set at zero while lead wires 20 and 21 are not connected to electrodes 15 and 16, and therefore the output voltage of amplifiers 24 and 25 is proportional to the currents flowing to lead wires 20 and 21. As a result, the vertical coordinates of the point 30 can be obtained from the ratio of output voltage between amplifiers 24 and 25. In the same way, it is possible to obtain the horizontal coordinates at the point 30.

Abstract: PROBLEM TO BE SOLVED: To effectively utilize quantization accuracy and to reduce a chip size or the like by using a non-linear processing circuit of a polygonal system. SOLUTION: An analog video signal outputted from a solid-state imaging device 11 is converted to a digital video signal while using an A/D converter 14 and at the time of performing signal processing concerning a chrominance signal and a luminance signal in a signal processing part 19, after the A/D converted digital video signal is compressed concerning the luminance signal and the chrominance signal, the digital video signals of plural lines are provided by using a line memory 18. After extending processing is performed to these digital video signals, a color component is separated.  Thus, color reproducibility is improved by using extended (restored) video signals for a chrominance signal processing system and characteristics equivalent to the case of extracting a contour from the luminance signal after gamma correction can be provided by using non-extended video signals for a luminance signal processing system.
