Title: Reactor container
Inventor: TAKIGAWA SADAHIKO
IPC: G21C15/18
Filed: 1991-05-30
Abstract: PURPOSE:To lower the volume of water source for emergency to lower the load of a container at the time of an earthquake and improve the stability of a plant building by installing a flow preventing means for cooling water which flows at the time of an accident in a vent pipe. CONSTITUTION:In the case that a pipeline 6 is ruptured and water pours itself into a pressure container 3 by a water pouring system 10 from a water source 11 for emergency, since the upper end part of a vent pipe 9 is extruded from a diaphragm floor 15, the cooling water 14 overflowing out of the ruptured part of the pipeline 6 does not flow in the pressure suppressing chamber 8. Consequently, it is not necessary to store water in the amount equivalent to the cooling water 13 of the chamber 8 in the water source 11 and thus the volume of the water source 11 can be lessened. a nuclear reactor container-lower part dry well communicating pipeline 16 which is communicated with a lower part dry well 5 and has a valve 8 is installed in the container 3. As a result, the cooling water 12 flowing in and stored in the dry well 5 flows to the container 3 through the valve 8 opened by an accident signal and the pipeline 16 and the water levels of the container 3 and the dry well 5 are balanced and the nuclear core 2 is submerged.

Abstract: PURPOSE:To provide a low-cost and easily manupulatable pulsed gas laser, which is capable of being preionized by an optical circuit of a simple constitution and is capable of contriving the prolongation of the life of laser gas. CONSTITUTION:A main electrode 2 for laser oscillation is installed in the interior of a laser tube 1 and a generated laser beam 3 is outputted via an output window 4. Amplification of the beam 3 is performed by a totally reflecting mirror 7 and a partially reflecting mirror 8.

Title: Semiconductor memory
Inventor: SHIMIZU MITSURU
IPC: G11C11/407
Filed: 1989-05-20
Abstract: PURPOSE:To perform the correct screening of a cell transistor by setting the voltage of a word line drive signal at a level higher than the normal action level when the power supply level is increased at a burn-in test. CONSTITUTION:When the row decoding output signal is set at the level of a power supply VCC, a 1st transistor(TN1) is turned on and the potential of a node B of the other end side is set at VCC - Vtn (Vtn: gate threshold voltage of TN1). The potential of the node B rises up until the junction breakdown occurs owing to the coupling of the TN1. As a result, the potential of a word line drive signal C rises up. When such actions are carried out at a burn-in test, the substrate bias voltage is lowered by the functions of a burn-in mode detecting circuit 14 and a substrate bias control circuit 15. Thus the potential of the node B satisfactorily rises up and the voltage of the signal C exceeds the normal action level. Then the signal C of a high level can be applied to a cell transistor. As a result, the screening of the cell transistor can be correctly carried out.

Title: Electrodeless discharge lamp apparatus
Inventor: KOBAYASHI KOICHI
IPC: H01J65/04
Filed: 1987-05-25
Abstract: PURPOSE:To maintain constant light emission on the whole area of the lamp in the caption by arranging, in a bulb, a means to form a discharge path going around along the inside of the bulb. CONSTITUTION:A lamp 21 is composed of a straight pipe-shaped bulb 22, a partition panel 28 as a means to form a discharge path going around along the inside of the bulb 22 is arranged in the bulb 22 and the partition panel 28 is formed as it divides the bulb 22 in two parts except both ends of the bulb 22. Further, a coil 26 is arranged on the outside of the bulb 22 along the go-around discharge path. Therefore, when a high frequency current flows through the coil 26, an induced current Ia flows as forming a loop in the lamp 21. In this case, even if electric power is lowered, the induced current Ia does not form any separate short circuit-loop but always maintains a loop along the coil 26. Accordingly, constant light emission on the whole area of the lamp is maintained.

Filed: 1980-09-16
Abstract: PURPOSE:To start steadily a metal vapor discharge lamp by means of a mercury ballast with a glow starter of which secondary voltage is 200V class, by setting the weight per a unit length of an electrode coil in the direction of an electrode stem to a higher level than specific value, according to the rated power of each discharge lamp. CONSTITUTION:The weight of a coil per a unit length M (g/mm.) calculated by dividing the total wight of the coil in the electrode coil unit 31 of the main electrode of a metal vapor discharge lamp such as a metal halide lamp or the like, by the coil length (l) in the direction of its electrode stem 30 is set respectively to 0.01, 0.03, 0.05, 0.08 or 0.1g/mm. according to the rated power of each discharge lamp, that is, 100, 250, 400, 700 or 1KW class. As the loss heat of the main electrode at the starting time of a discharge lamp is caused mainly by the heat transmitted to the tube wall of a luminous tube 2 through the electrode stem 30, the temperature of the main electrode rises quickly accordingly as the weight of the coil per a unit length increases. Thereby, the metal vapor discharge lamp of each rated power can be started steadily and quickly by a mercury ballast with a glow starter of which secondary voltage is 200V class.
