Title: Manufacture of multiple electron beam source, device therefor, and manufacture of display device having the same and device therefor
Inventor: SUZUKI HIDETOSHI
IPC: H01J1/30
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a uniform electron emission characteristic by generating a forming voltage that rises with time while its rate of rise decreases, and performing a forming process while providing a connection so that the voltage can be applied to a plurality of electron emitting elements. SOLUTION: A forming voltage source 2 produces a voltage which increases in amplitude with time while the rate of increase of the amplitude decreases with time. The voltage source 2 is connected to the row wiring of an M×N electron-emission-element simple matrix 1001 via a switching-element array 3, and the forming voltage is applied to the surface conduction type emitting elements to form electron emitting parts. Since the rate of rise of the forming voltage decreases with time, even if the elements at a row end are given high resistance, fluctuation of the applied voltage can be reduced, so that uniform forming can be achieved throughout the row of elements.

Filed: 1980-12-12
Abstract: PURPOSE:To generate many kinds of test currents by applying the test currents, which are obtained by selectively applying the output signal of a decoder based on the output of a counter to an operation amplifier, to a test coil. CONSTITUTION:An address signal for the seismometer to be tested is outputted from a processor 5, and a datum ''1'' is sent to a data bus. An address detector 7 decodes the address signal, and outputs a ''0'' to an FF6 when the address is for its own seismometer. At this time, since a ''1'' is inputted to a terminal D of the FF6 from the data bus, a ''1'' is outputted from a terminal Q. A frequency divider 9 divides a reference clock from a reference clock oscillator 8, and outputs the divided clock to a counter 11. Outputs generated at output terminals QA and QB thereof are applied to input terminals A and B of a decoder 12. Outputs are generated at output terminals D0-D3 thereof. Then, an output is generated from the operation amplifier 14 and inverted at the operation amplifier 15. As a result an output is outputted from a protecting part 16 and applied to the test coil 4.

Abstract: PURPOSE:To prevent the reconduction of an MOSFET and the breakdown of a gate insulating film by controlling the potential increase of the emitter region involved with the interruption of a short-circuiting MOSFET (emitter switch) at the time of turning off in the structure of EST (emitter switch thyristor). CONSTITUTION:The structure of this semiconductor device comprises an EST part 30 and an IGBT part 40. The EST part 30 has a first MOSFET 12 and a second MOSFET (emitter switch) 13 for switching synchronization, and the IGBT part 40 has a third MOSFET 23 which can be controlled independently thereof. At the time of turning-off of EST, when the first and the second MOSFET 12, 13 are turned on with the third MOSFET 23 being turned on, the IGBT part remains operated and therefore a current path for an emitter region 6 is changed to the emitter electrode 8 side even when the recovery of a potential barrier due to the junction of the emitter region 6 is delayed, so that the storage of an electric charge into the emitter region may be controlled. After the recovery of the potential barrier, the third MOSFET 23 is turned off, so that a controllable turn-off current may be made larger and at the same time the turn-off time can be shortened.
