Title: Multi-electron beam source and image display device using same
Inventor: SUZUKI HIDETOSHI
IPC: H01J1/316
Filed: 1990-05-23
Abstract: PURPOSE:To prevent a spike shape reverse voltage from being applied to an electron emission element and to prevent degradation or destruction in electron emission characteristics by arranging rectifier elements in parallel with each line of electron emission elements which are electrically connected in parallel. CONSTITUTION:Diodes D for rectification are arranged at every electron emission element ES line in parallel with electron emission elements. The orientation of the diodes D in an arbitrary n-th line is arranged with its anode being connected to a wiring electrode Em+1 and its cathode being connected to a wiring electrode Em. Accordingly, when electron emission element lines are driven, the electron emission element driving voltage VE works as a reverse voltage and the spike shape voltage SPi-1 works as a forward voltage to the diodes D. Therefore, since a spike shape reverse voltage SPi-1 is not applied, in each line of electron emission elements, phenomena such as degradation and destruction in characteristics of electron emission elements do not occur.

Title: Gas insulated electric apparatus
Inventor: HORII SHIGENOBU
IPC: H01F27/20
Filed: 1988-05-30
Abstract: PURPOSE:To reduce the size of an apparatus by arranging wicks along the vertical direction in a heat generator member disposed within an enclosed container and immersing a lower end part of the heat generator member into a reservoir to thereby efficiently execute an effective heat exchange. CONSTITUTION:When a transformer is used, an iron core 6 is heated because of excitation. Wicks 7 disposed within the iron core 6 heat and evaporate a cooling medium 5 sucked from a reservoir 4. At this time, latent heat during evaporation is lost, and as a result, the iron core 6 is cooled. The gasified cooling medium 5 is diffused into an insulating gas within the enclosed container 1 and reaches a cooling device 2. In a section of the cooling device 2 in which processes such as convection, radiation, and thermal conduction are utilized, the heat of the gasified cooling medium 5 is dissipated into the air. As a result, the vapor of the medium is condensed and liquefied, and returns to the reservoir 4 through a cone-shaped liquid collecting bottom 3 to be reused for cooling. Accordingly, the heat exchange can be executed efficiently and thus the size of the apparatus can be reduced.

Filed: 1979-10-16
Abstract: PURPOSE:To eliminate the undesired electric wave having the same frequency as the desired signal without any large-size antenna, by giving a control to the reception antenna by the control signal obtained from the output of the undesired electric wave receiving antenna. CONSTITUTION:The null of the directivity is turned toward the direction of thetad of the desired signal for the element antenna which forms the undesired electric wave receiving array antenna 2. Thus only the undesired electric wave is received through the antenna 2. As a result, the arriving direction of the undesired electric wave is detected by the detecting circuit for undesired electric wave arriving direction 5.  And then the directivity control circuit 4 is controlled by the output signal of the  control signal generating circuit 6 which supplied the detection output of the circuit  5. Thus the null direction of the directivity of the reception antenna 1 can be turned to the arriving direction of the undesired electric wave. As a result, the antenna 1 does not receive the undesired electric wave to realize a reception with a high S/N.

Title: Ignition-extinguishing circuit for gate turn-off thyristor
Inventor: OGAWA NOBORU
IPC: H02M1/08
Filed: 1977-11-07
Abstract: PURPOSE:To make it possible to make a disconnection between the anode and cathode of a GTO completely with the need of a control power supply eliminated, by igniting the GTO at the rise of an input pulse and by extinguishing it at its fall. CONSTITUTION:When a pulse is supplied from input terminal P, the rise of the pulse is supplied to gate G of GTO1 via diode 19 and capacitor C12, so that GTO1 will conduct. On the other hand, C14 is charged via resistance R13. Next, since, transistor Tr17 does not conduct when an input pulse rises, the charge of C14 is supplied to the base of Tr15 via R16 and Tr15 conducts to supply the energy accumulated in C12 as a reverse bias current, thereby stopping GTO1. Consequently, the GTO can be made to conduct at the rise of one input pulse and cut off at its fall.
