Title: Lighting device
Inventor: YOSHIKAWA KAZUHIKO
IPC: H01J61/16
Filed: 1990-06-18
Abstract: PURPOSE:To increase the quantity of light of a lamp at its starting time while simplifying also a power supply without lowering the restarting property of the lamp by changing the lighting frequency of the lamp given at the starting time thereof until the stable lighting condition of the lamp is established immediately after the lamp is lit to be lower than the lighting frequency of the lamp given when the stable lighting condition thereof is established so that impedance in a coil may be lessened. CONSTITUTION:When a pulse is applied by an inverter 2, a filled rare-gas causes dielectric breakdown to initiate electric discharge so as to promptly initiate its radiation. Then the gas increases the lighting frequency of a lamp in accordance with a change in a lamp voltage while the lamp reaches its steady condition. Namely, because impedance in a coil 3 becomes low at the starting time of the lamp when the frequency of an output from the inverter 2 is low, a current flowing through the lamp 4 becomes large in volume to promptly cause dielectric breakdown of the rare gas filled under high pressure so as to effectively obtain an optical output resulting from the electric discharge of the rare gas.

Title: Helium leak detector
Inventor: OKAMOTO HIDEKI
IPC: G01L21/00
Filed: 1995-06-26
Abstract: PURPOSE: To resume the leak test effectively by lowering the background level at a mass spectrometric section quickly even when a large quantity of He is mixed into an oil in an oil-sealed rotary vacuum pump due to gross leak. CONSTITUTION: When a measurement at a mass spectrometric section ANAL exceeds a threshold level, a microcomputer unit 4 judges that gross leak has occurred, and controls a solenoid valve GBV fixed to the gas ballast port 21 of an RP2 to open for a predetermined time. Consequently, atmospheric air is introduced through the gas ballast port 21 into the RP2 and He bubbles in the oil are stirred to be discharged quickly through the RP2. Since no He is discharged again from the RP2 at the time of leak test after occurrence of gross leak, the problem of increasing background level at the mass spectrometric section ANAL is solved.

Title: High voltage direct current measuring apparatus
Inventor: TSUJII KOUICHI
IPC: G01R19/25
Filed: 1979-12-10
Abstract: PURPOSE: To make possible the measurement of high-voltage DC voltage and the detection of the danger accompanied with thunderclouds with ease and accuracy by detecting the electric field owing to the thunderclouds and processing the detected current through an optical transmission system.  
     CONSTITUTION: The electric field of thunderclouds is detected with an electrode 1, and the detected current thereof is accumulated in a capacitor 3 via a resistance 2. When the terminal voltage of the capacitor 3 reaches a predetermined value, discharge current flows in a discharge gap 5 via a current limiting resistance 4, thereby causing an LED 6 or 7 to emit light. Then, if the terminal voltage of the capacitor 3 drops below the predetermined value, the discharging of the gap 5 stops. The light emission frequencies of the LED accompanied with the repetition of this discharge starting and discharge stopping are proportional to the detected current. The thus obtained light signal is sent to a current measuring apparatus 30 via optical fibers 40 and based on the measured value thereof, the proximity state of the thunderclouds is detected.
