Title: Bias circuit
Inventor: SHIBUYA KENICHI
IPC: H04N5/60
Filed: 1987-05-21
Abstract: PURPOSE:To prevent the sudden rise of a reference bias voltage when a power source is re-charged by detecting the fall of a source voltage, and accordingly discharging the charge of a bypass capacitor connected with a voltage-dividing resistance. CONSTITUTION:When the charge of the bias capacitor 21 is set to be discharged based on a comparison output voltage between a comparison voltage Vc which follows the source voltage VCC and changes and the voltage-dividing voltage VD1, the charge of the bypass capacitor 21 can securely be discharged before the source voltage VCC falls to 0 [V] since the comparison voltage VC is set to be outputted through a level shift circuit 45 if the source voltage VCC is off-operated. Thus, the sudden rise of the voltage-dividing voltage VD1 when the power source is re-charged can previously be prevented.

Title: Direct current driving type superconducting memory circuit
Inventor: HATANO YUJI
IPC: H01L39/22
Filed: 1988-05-25
Abstract: PURPOSE:To prevent latch-up without damaging the characteristic of direct current drive and to stabilize operation by adding a resistor between first and second terminals of a memory in a direct current drive baffle type FF. CONSTITUTION:Magnetic flux coupling type gates 113 and 114 of a superconducting memory circuit to form the direct current drive baffle type FF are respectively driven by direct current sources 111 and 112 together with resistors 115 and 116, which are connected between terminals 113-1 and 114-2, and a current Iout in a different direction is detected by the gates 113 and 114 in a voltage condition. Then, information 1 and 0 are read. A resistor 130 is connected between these terminals 113-1 and 114-2 parallelly with the serial resistors 115 and 116 and when the gates 113 and 114 simultaneously are going to the voltage condition, one gate can not maintain the voltage condition but returns to a voltage-zero condition.

Title: Method for cutting and removing masking sheet for processing silicon wafer
Inventor: RI MASAHIRO
IPC: H01L21/304
Filed: 1985-06-10
Abstract: PURPOSE:To automate the process for improving the productivity as well as for increasing the yield rate of wafers by successively paying out and contacting an energized heating wire with the outer periphery of a rotating wafer so as to cut away the out sheet portion, and thereafter successively paying out and contacting a non-energized wire with the outer periphery of the rotating wafer. CONSTITUTION:Since a rocking plate 6 approaches in the direction of an arrow 6 to the outer periphery of a rotating silicon wafer 1, a heated energized heating wire 13 (heater wire) contacts therewith, so that the out sheet portion 3' of a masking sheet 3 is cut away along the outer periphery of the silicon wafer 1. Further, since a non-energized wire 13' (dummy wire) which is not heated comes into contact with the portion under the energized heating wire 13, the out sheet 3' which has been cut off, and lumps or refuses of the sheet produced by the heating are surely separated from the silicon wafer 1, and the dust sheet 3'' which has been cut off falls below. The angles between the silicon wafer 1 and the energized heating wire 13 and the non-energized wire 13' are somewhat wider than right angle at the outer periphery of the silicon wafer 1 with regard to the direction in which the wire is running.

Title: Heat exchanger made of ceramics
Inventor: SUGITA RYUICHI
IPC: F28F21/04
Filed: 1985-06-12
Abstract: PURPOSE:To eliminate generation of thermal stress as well as possibility of breakage by a method wherein a composite tube, consisting of an inner tube contacting with a fluid from a cool air inlet port and an outer tube contacting with high-temperature atmosphere, is structured so that both of the inner and outer tubes are elongated freely even when the difference of elongations is generated therebetween by a temperature difference. CONSTITUTION:The cool air, entered from the cool air inlet port 1, deprives heat from warm- air in the outer heat transfer tube 3 through the pipe wall of the inner tube 4 under the process of passing through the inner heat transfer tube 4. On the other hand, the cool air deprives heat from high-temperature gas in a casing 7 through the pipe wall of the outer heat transfer tube 3 under the process of turning its direction at the bottom of the outer heat transfer tube 3 and passing through a gap 14 whereby the temperature thereof is increased and, thereafter, flows out of a hot air outlet port 2. The difference of elongations is generated between the inner heat transfer tube 4, contacting with the fluid entered from the cool air inlet port 1, and the outer heat transfer tube 3, contacting with the high-temperature gas, due to the temperature difference. However, the composite tube has a structure which allows both inner and outer tubes to elongate freely into the lengthwise direction without being constrained mutually, therefore, thermal stress will never be generated and there may be no possibility of being broken.
