Title: Data transfer device of camera
Inventor: TAMAMURA HIDEO
IPC: G03B17/24
Filed: 1984-02-25
Abstract: PURPOSE:To prevent erroneous operations in water by providing one mode lock push button switch, which has a depression area larger than that of a data input push button switch and makes data input ineffective, at least. CONSTITUTION:When a camera is put in water and a water pressure is increased, one of switching buttons 4a-4f is deformed, and corresponding one of switches 18a-18f is made conductive, and the potential at corresponding one of points (i)-(n) is changed from the low level to the high level, but signals are not inputted to a data transfer and display IC14 from AND gates 8-13 because the potential at a point (g) is in the low level. In case that data is selected or corrected on the ground, the potential at the point (g) is in the high level because a mode lock button 5 is restored by elasticity. When desired one of switching buttons 4a-4f is depressed, corresponding one of switches 18a-18f is made conductive, and the potential at corresponding one of points (i)-(n) goes to the high level, and signals are inputted to the data transfer and display IC14 from AND gates 8-13 to select or correct required data.

Title: Low-pressure wafer bonding system
Inventor: KAWAMOTO TOSHIRO
IPC: H01L21/02
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a low-pressure wafer bonding system that reduces damages to each wafer, when a plurality of wafers are permanently bonded onto a carrier plate in a batch. SOLUTION: A carrier plate 12, on which a plurality of silicon wafers W have been temporarily bonded, is placed on a table 13. A pressure reducing cover 15 is placed on a main body pedestal 11 to seal the table 13. An air suction pump 20 is used to make negative pressure inside of the pressure reducing cover 15. If a doughnut-shaped pressure balloon 14 is blown up by an air supply pump 18, the bonding surface between each wafer W and the plate 12 is degassed due to the decompression effect in the cover 15. Wafers W placed around the plate axis line are bonded with pressure relatively gently on the carrier plate 12 in a batch by the balloon 14. As a result, damages to the wafers W is reduced, when they are bonded permanently.

Filed: 1990-02-16
Abstract: PURPOSE:To realize the correct recording operation and the correct erasing operation of information by controlling the size of a magnetic field generated from a magnetic field impressing electromagnet. CONSTITUTION:An oscillator 1, a triangular wave generation circuit 2, a D/A (digital/analog) converter 3, a comparator 4, an adder 5, inverters 6, 7, AND gate circuits 8, 9, an electromagnet 10, switching transistors Q1 to Q4, and a current detecting resistor R5 are provided. Then at the time of the recording of the information, by giving S1 of one side by 'H' and S2 of the other side by 'L' between two pieces of exciting current control signals S1, S2, the recording operation, for instance, is executed. At the time of erasing, by giving the exciting current control signal S1 by 'L' and S2 by 'H', the erasing operation is executed. At the time of reproducing, since both exciting current control signals S1, S2 are given by 'L', an exciting current is not generated. Thus, the recording and the erasure can be executed always in an optimum state.

Abstract: PURPOSE:To obtain a porous membrane having a uniform fine porous structure and excellent chemical resistance, heat resistant, filterability and mechanical properties, by adding a chlorotrifluoroethylene oligomer to a specified ethylene- containing copolymer fluororesin, melt-molding the mixture and extracting the oligomer from the molding.

The chlorotrifluoroethylene oligomer is extracted from this molding to obtain the purpose membrane. As the chlorotrifluoroethylene oligomer used, a tetra- to eicosa-me is desirable. A trimer or a lower oligomer is not desirable because the heat resistance is low, volatilization during melt molding is large, and the permeability of the porous membrane is small. A heneicosaner or a higher oligomer is not desirable because workability in mixing and extractability are poor.

Abstract: PURPOSE:To reduce the cost per one chip in large scale circuit integration by detecting an error bit number between a pattern set to each pattern setting register and reception data, using each circuit section in common to reduce the gate number. CONSTITUTION:N kinds of different patterns are set to a pattern setting register 1.
