Title: Charged particle sensor
Inventor: SHIMOMA GOROKU
IPC: H01J37/244
Filed: 1989-04-28
Abstract: PURPOSE:To prevent attachment of or remove contaminants from each step dinode of a secondary electron multiplexer tube and prolog the lifetime of a secondary ion sensor by furnishing a means to heat the secondary electron multiplexer tube. CONSTITUTION:Secondary ions 1 are deflected by a deflecting electrode 2 in order to remove neutral particles and irradiated to a first step dinode 3, where secondary electrons are emitted. Secondary electrons are accelerated and bombarded one after another in later dinodes 4 than the second step dinode to be multiplexed exponentially, and the multiplexed secondary elements are amplified by an amplified 6 and sensed. Contamination attached when secondary electrons are bombarded to each step dinode are prevented by heating the each step dinodes 3, 4 of the secondary electron multiplexer tube 5 with a lamp 7, and eventually attached contaminants are removed by baking process. This prolongs the lifetime of a secondary ion sensor.

IPC: H01J9/20
Filed: 1980-08-07
Abstract: PURPOSE:To obtain a rapid start fluorescent lamp which has a small deviation of electric resistance and stable starting characteristics, by coating the inner wall of a glass case with a transparent conductive film made of tin oxide or the like, a phosphor film and an antimony oxide film, in that order. CONSTITUTION:The inner wall of a tubular glass case 1 is coated with a transparent conductive film made of a tin oxide, before it is coated with a phosphor film. Then, the case 1 is transferred to the next process, to an antimony trioxide film coating device 2. A hermetically sealed case 3 of the device 2 contains an antiomny trichloride liquid 5, which is prepared by melting antimony trichloride powder put in the case 3 by means of a heater 4. The space over the liquid 5 is filled with an evaporated steam 6. Antimony trichloride sent into a case 1 held by a holder located in a heating furnace 9, is oxidized within the furnace 9 through thermal decomposition into antimony trioxide, which is made to adhere to the inner wall of the glass case 1. Consequently, a rapid start fluorescent lamp can be obtained with such a simple device and by such a simple method.

Title: Thyristor converter commutation failure protecting system

Filed: 1978-09-05
Abstract: PURPOSE: To prevent a thyristor converter from failing in commutation with a simple circuit configuration by providing an allowable angle detecting circuit for producing its output when the allowable angle of the thyristor is lower than predetermined value to thereby advance the firing phase to predetermined phase.  
     CONSTITUTION: In order to detect the reverse voltage of one of bulbs 21 in a thyristor converter consisting of a plurality of thyristors, a reverse voltage detecting circuit 23 generally connected to a light guide or the like for transmitting a light signal detects the higher reverse voltage than the reverse voltage detecting level of the voltage waveform applied to the thyristors to apply the detected voltage to an AND gate AND-1. A pulse control circuit 22 produces a pulse control signal, which is inverted via an inverter circuit INV-1 to apply the inverted signal to the other input of the AND gate AND-1. The output of the AND gate AND-1 is applied to an AND gate AND-2. When the allowable angle is insufficient, the AND gate AND-2 produces a commutation failure protecting signal to thereby rapidly advance the phase so as to prevent the thyristors from failing in commutation twice or three times.
