Title: Infrared ray detector
Inventor: MIYAMOTO KEIJI
IPC: H01L31/00
Filed: 1986-08-15
Abstract: PURPOSE:To eliminate a temperature variation at the time of replacing an aperture with an infrared ray transmission filter and to shorten a processing time by providing holding means which can detachably hold the filter and the aperture in a liquid nitrogen. CONSTITUTION:Two liquid nitrogen reservoirs 7 are provided, an infrared ray detector 1 is closely contacted with one reservoir at a heat insulating vacuum tank 6, and an aperture 2 and a filter 3 are secured to the other reservoir in liquid nitrogen 8. Three infrared ray transmission windows 4 are formed, and set in size so as not to disturb the visual field of the detector 1 determined by the aperture 2. When replacing the aperture 2 or the filter 3, a grip 9 as holding means made of rubber or cork having low thermal conductivity is raised, and the aperture 2 and the filter 3 are removed from the nitrogen 8. Thus, the aperture 2 and the filter 3 can be rapidly replaced.

Title: Phase detecting circuit
Inventor: NOMURA YASUHISA
IPC: G01K7/00
Filed: 1993-06-21
Abstract: PURPOSE:To allow highly precise harmonic-free detection of phase difference through simple circuitry by dividing an AC voltage through a resistor and a capacitor and measuring the phase difference of an object through the use of the divided voltage. CONSTITUTION:Voltage of an AC power supply 1 is divided by resistors R, R2 and a capacitor C before being applied to an object 10. When the voltage is applied forward to a diode D2, i.e., for the positive half wave of voltage, voltage is applied to the collector of a transistor Q but no voltage is applied to the collector for the negative half wave of voltage. On the other hand, base current flows into the transistor for the positive half wave of current, but current flows through a path of one end 1b of resistor R2-diode D1-object 10other end 1a of resistor R2 for the negative half of current and no base current flows into the transistor Q. Consequently, the duration of collector output P when a forward voltage is applied to the diode D2 but base current does not flow into the transistor Q is detected as the phase difference between the applying voltage and current of the object 10.

Title: Mercury carrier, its manufacture, and fluorescent lamp
Inventor: NAGAI HIDEO
IPC: H01J61/28
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a mercury carrier body and its manufacturing method, enabling all mercury in a glass capsule to be surely released into a discharge space in a fluorescent lamp, and to provide a fluorescent lamp capable of preventing its failure to light due to lack of mercury. SOLUTION: A mercury drop 2 is sealed in a glass capsule 1. The glass capsule 2 is made of soda glass including copper ions. The copper ions included in the glass enhance the heat conductivity of the glass. Consequently, the mercury in the glass capsule 1 is heated to high temperatures to be gasified, and explosively released from the glass capsule into a discharge space in a fluorescent lamp at the same time as the glass capsule is broken. Because of the metallic ions included in the material of the glass capsule 1, the glass itself can be expected to generate heat by a high frequency, thus enabling the mercury to be more surely released into the discharge space.

Abstract: PURPOSE:To prevent reverse tidal-current from being caused to the side of an utility system by absorbing the excess energy of a generator into a spare load for a fixed time when load current is suddenly reduced in the generation equipment using the generator having slow response to power command. CONSTITUTION:When constant load current fed from a generator and an utility system is suddenly reduced to I2 from I1, it is detected by a controller 1 that the situation of reverse tidal-current generation is generated from the current change of current transformers CT2, CT1, and a switch 3 is closed, and spare load current I3 for compensating load current reduced-component I1-I2 is permitted to flow. After this, by the controller 1, from the quantity of the load current I2, electric energy to be generated from the generator is computed, and power command is reduced to P2 from P1. When generator output is turned into P2 and is stabilized, then by the controller 1, the output of signal for disconnecting a spare load 2 is directed to the switch 3.
