IPC: G21C3/30
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide the channel box and manufacturing method thereof, wherein the overall corrosion-resistance property covering nodular corrosion is enhanced in consideration of the state of the cooling water in a reactor core. SOLUTION: In a channel box 1a of the fuel for a light water reactor in a tube body formed of zirconium-based alloy, the diameter of the deposited particle of the alloy component of a boiling region 12 of the tube body is set at 0.2μm or less. Furthermore, the grain diameter of the deposited material in a non-boiled region 13 of the tube body is set at 0.2μm or more. Since the grain diameter of the deposited material in the boiling region 12 is small, the nodular-corrosion resistance is excellent. Since the grain diameter of the deposited material in the non-boilded region 13 is rough, the characteristics excellent in uniformity resistance is displayed. Thus, the overall corrosion resistance can be enhanced.

Abstract: PURPOSE:To adjust the intensity of a current obtained through photoelectric conversion of each color light to a constant level without using an external device by providing a photosensitive layer having the thickness corresponding to the wavelength of a light of a specific color on an insulative substrate. CONSTITUTION:A buffer layer 2 made of silicon nitride is formed on an insulative substrate 1 through plasma CVD or the like, and a pair of electrodes 3a, 3b of aluminum, chromium or the like are formed on the buffer layer 2. There is formed a photosensitive layer 4 having amorphous silicon piled on the electrodes 3a, 3b. A protecting layer 5 is formed by piling silicon nitride on the photosensitive layer 4. The photosensitive layer 4 is made thin for a blue light, while it is made thick for a red light.

Filed: 1978-06-28
Abstract: PURPOSE:For reducing the whole structure of this system, to generate partial discharge between the third electrode provided in the vicinity of a cathode and said cathode so that no high voltage may be impressed between the cathodes of a plurality of discharge tubes. CONSTITUTION:Third electrodes 20A and 20B are provided in the vicinity of the cathodes of first and second discharge tubes 2A and 2B, and connected to the + side terminal of a DC power source 12 through the medium of a high-resistor 21 by means of an electric wire 22. Immediately after the start of the discharge of said discharge tube 2A which has made the first discharge after starting, said discharge tube 2B does not start main discharge, but partial discharge is generated between a cathode 4B and an electrode 20B. Therefore, the voltage between cathodes 4A and 4B does not become excessive since the voltage of said cathode 4B is lower than that generated by a DC power source 13. Consequently, the insulation distance l between insulating tubes 5A and 5B can be decreased. If said third electrodes 20A and 20B are installed on the flow lower gas flow course side of said cathodes 4A and 4B, good results can be obtained since charge particles easily reach anode side.

Filed: 1985-04-12
Abstract: PURPOSE:To cut down the material cost and the mounting time by a method wherein a heat-radiating plate having a protrusion and a U-shaped spring are provided. CONSTITUTION:A cylindrical protrusion 11 attached to a heat-radiating material 8 is brought into contact with the mounting surfaces of the lead legs 10 of a transistor 7 and is positioned. This is because the force to be applied to the transistor 7 when a U-shaped spring 12 is inserted in the heat-radiating material 8 is received by the cylindrical protrusion 11 and the force is prevented from applying to the copper foil 13 of a printed substrate 9. By eliminating the cylinder between the printed substrate and the transistor main body, the material cost and the mounting time to be needed when the cylinder material is used can be cut down.
