Abstract: PROBLEM TO BE SOLVED: To provide a pierced electron gun which is made easy to assemble by reducing the number of parts while suppressing increase of consumed power and increase of perveance in a heater. SOLUTION: The electron gun equipped with a Wehnelt electrode for focusing an electron beam has a structure having a negative electrode emitting electrons, a heater cap having a built-in heater giving the negative electrode thermal energy for emitting the electrons, a retainer for fitting a peripheral edge of the negative electrode to the heater cap to provide and fix the negative electrode on to the heater cap, a Wehnelt electrode part formed in a shape that a mean angle of the surface conforms to a piercing angle, and a Wehnelt support, in which at least 3 heater cap supporting members for supporting and fixing the heater cap in such a manner that an electron emitting surface of the negative electrode and an opening provided in the Wehnelt electrode part are located at positions satisfying a prescribed perveance have been integrally formed.

Abstract: PURPOSE:To certainly detect any stop of power supply from a main power source and release a decentralized type power source from a power system so as to enable linkage to be automatically recovered in the case of recover by making switching operation between the decentralized type power source and the power system depending upon presence or absence of any amount of variation in the power system. CONSTITUTION:Electric power from the power system A of a main power supply 1 is supplied to a system linking device 13 through a lead-in wire 7 and also supplied to a household electric load 10 via a circuit breaker 8. DC current of a solar cell (decentralized type power source) 11 installed in a home 9 is inverted in AC current of 60Hz through an inverter 12 and supplied. When a circuit breaker 4 is opened for the purpose of wiring work, etc., from a normal state with both circuit breakers 4 and 8 closed, elimination of a variation in the frequency of power system A is sensed by a frequency difference detecting means 14 and a command means 16 gives a release instruction to the circuit breaker 8 to separate the solar cell 11 from the power system A. When the work is completed and the circuit breaker 4 is closed, the means 14 senses a frequency variation, the means 16 gives a close instruction to the circuit breaker 8 so as to link the solar cell 11 to the power system A automati cally.
