Title: Driving method for pulse generation circuit
Inventor: KONO HITOSHI
IPC: H03K17/60
Filed: 1990-01-30
Abstract: PURPOSE:To obtain normal output pulses even from the first pulse without a bad influence of the voltage of a capacitor at the time of starting the operation by discharging the stored energy of the capacitor at the time of stopping the operation in the case of a pulse transformer whose input circuit has the capacitor. CONSTITUTION:When the operation of a driving circuit is stopped, a negative pulse is given to transistors TRs 1 and 2 for a prescribed time DELTAt to surely turn off them, and thereafter, the stored energy of a pulse transformer 4 is sufficiently discharged to a capacitor 3 with the on-state resistance of a switch 13 and the energy stored in the capacitor 3 is consumed by a discharging resistance 12. Consequently, the pulse transformer 4 sends the normal pulse having equal positive and negative crest values even from the first pulse when the driving circuit is started again.

Title: Luminance multiplier tube
Inventor: YOHANESU KAARU EWARUTO KORUDEI
IPC: H01J29/38
Filed: 1995-02-06
Abstract: PURPOSE: To provide a luminance multiplying tube indicating intensified sensitivity with respect to conversion of an incident radiation. CONSTITUTION: For increasing sensitivity of a luminance multiplying tube, efficiency of an electronic image formed on the basis of radiation on the first wavelength is increased. The radiation of the first wavelength is converted into the radiation of the second wavelength by means of a conversion screen 3 arranged in a scintillation layer 22, and the radiation of the second wavelength emits an electron from a photocathode, responding to the second wavelength. A loss, which is caused because this radiation part does not reach the photocathode, in the radiation of the second wavelength is reduced. The radiation of the second wavelength, which is not emitted in the direction of the photocathode, is caught again when a metallic reflection intermediate layer 21 is arranged in the conversion screen 3.

Abstract: PURPOSE:To prevent the generation of an unnecessary digital signal by operating a detection value updating means forcedly by an oscillator when a regenerative signal is constant. CONSTITUTION:An input light signal is inputted to a peak hold circuit 2 and an offset circuit 3 through a converter 1.

Title: Suction device
Inventor: ITO KENGO
IPC: F04B45/04
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an abnormal rise of the suction pressure. SOLUTION: This suction device carries out the suction by generating a negative pressure by the variation of the inner capacity of a pump chamber 12 by the reciprocating drive of a diaphragm 10.

Title: Device for controlling circular glass tube formation furnace
Inventor: KANEKO HIROSHI
IPC: H01J9/24
Filed: 1985-02-06
Abstract: PURPOSE:To keep a heating furnace in a condition appropriate for annular formation, by putting a timer in operation for a set time to disconnect a generated heat quantity controller and a heating section from each other to avoid the influence of the operation of the controller. CONSTITUTION:As soon as a PID temperature controller 1 generates an output signal, a timer 9 starts acting. As soon as the timer 9 finishes acting, another timer 10 starts acting to disconnect the PID temperature controller 1 and a gas flow rate controller 3 from each other. During the disconnection, the gas flow rate controller 3 does not act even if the PID temperature controller 1 generates the output signal. During the disconnection, an annular glass tube formation furnace 7 gradually returns to the original condition because of the first time of gas flow rate change. The furnace 7 remains in the condition until the time 10 finishes acting. The furnace 7 returns to a normal production condition after the timer 10 finishes acting. The furnace is thus kept in a condition appropriate for annular formation. As a result, the efficiency of work is enhanced and the ratio of defectiveness is diminished by 30%.
