Title: Cooling system for natural heat radiation type nuclear reactor containment
Inventor: SAITO NOBORU
IPC: G21C9/00
Filed: 1989-03-28
Abstract: PURPOSE:To stably cool a nuclear reactor vessel for a long period by providing a dry well with a transmission tube and connecting it to a water replenishing pool and a stack on the outside of the nuclear reactor containment to discharge the heat in the nuclear reactor containment to the air. CONSTITUTION:At the time of an accident steam filled in a dry well 3 passes a vent tube 7 to depress water in the vent tube 7 and flows up to the lower part in a suppression pool 4, and high-temperature and high-pressure steam transmits heat to water in the suppression pool 4 and is condensed. The temperature of water in a heat transmission tube 10 rises by condensation of steam in the vapor-phase part in the dry well 3 and flows into an upper plenum 9a as two-phase currents while boiling. Vapor and water are separated in the upper plenum 9a, and steam is discharged to the air from a stack 15 through a piping 17b. Thus, heat in the nuclear reactor containment is discharged to the air, and the nuclear reactor containment is stably cooled for a long period.

Abstract: PURPOSE: To let glass plates have convex face always on the transparent electrode side and make possible correction by clearance correcting material by using material of a large coefficient of thermal expansion for the glass plates and beforehand heating the glass plates at the forming of the transparent electrodes.  
     CONSTITUTION: As upper plate glass or lower plate glass, float glass of an extremely large coefficient of thermal expansion, e.g., lead glass 10, is heated preferably to 400 to 500°C. In this state, transparent electrodes 11 having a coefficient of thermal expansion smaller than the coefficient of thermal expansion of the glass 10 are formed on one side of the glass 10 by a suitable thin-film forming apparatus. An or entation control film 12 is also formed by the method equivalent to the forming method of the electrodes 11 or coating such as of PIQ. Such production process causes warp bending having convex face on the electrode 11 side like b because the shrinkage of the glass 10 is larger than the shrinkage of the electrodes 11 when the glass 10 is slowly cooled down to ordinary temperature after the formation of the electrodes, etc.

Title: Gas laser oscillator
Inventor: ISHIKAWA KEN
IPC: H01S3/038
Filed: 1988-03-30
Abstract: PURPOSE:To simplify a structure and to eliminate a trouble by rotatably providing at least one of a pair of main electrodes disposed oppositely in space in a sealed vessel, and rotating the main electrodes by gas laser medium to be supplied into the vessel. CONSTITUTION:A cathode 2 for forming a main electrode and an anode 3 facing above the cathode 2 are disposed in a sealed vessel 1 of a gas laser oscillator. Gas laser medium supplied from one end of a circulation passage 18 into the vessel 1 by a blower 19 is forcibly circulated through a discharge space 14 designated by an arrow to return to a circulator 18. When the medium passes the space 14, its dynamic pressure is operated to the vane 7 of a dynamic pressure retainer 6 formed at both ends of the cathode 2. Thus, the cathode 3 is rotated by the medium flowing in the space 14. Discharging product does not adhere to the surface of the cathode 2 rotated thereby, and yet even if it adheres thereto, the part does not always face the anode 3. Thus, when a pulse discharge is repeated at a high speed, an adverse influence of the product to the next discharge can be reduced.
