Title: Dish dryer
Inventor: KIMURA HIDEO
IPC: A47B77/08
Filed: 1989-03-15
Abstract: PURPOSE:To improve the water-sealing property and airtight property of a door and prevent the discoloration and corrosion of a decorative sheet by interposing a packing between an intermediate plate and a sash which constitute the door, and providing a protrusion on the intermediate plate. CONSTITUTION:A packing F13 is interposed between a sash 10 and an intermediate plate 15 and sealed thereto to prevent the entrance of drops between the sash 10 and the intermediate plate 15 when a door is opened to contain dish away. To prevent the escape of steam during drying operation, one side of the packing 13F is extended and made into contact with a bottom plate 3c. Even if water infiltrates between the sash 10 and the intermediate plate 15, the water never reaches a decorative sheet by providing a protrusion 4a on the front side of the intermediate plate 15 bottom part.

Title: Wrapper tube for fuel assembly of nuclear reactor and its manufacture
Inventor: NAKAHIGASHI SHIGEO
IPC: B21C1/22
Filed: 1978-05-24
Abstract: PURPOSE: To regulate the swelling of individual parts on purpose to prevent the bending of the wrapper tube, by making larger the cold working ratio for the material of the part nearer to the middle of the reactor core, than the material of the part farther than the middle of the reactor core.  
     CONSTITUTION: The stainless steel is employed for the structural material of the horn pipe of the fast breeder reactor. The larger the cold working ratio of the stainless steel is, the lower the increasing rate of swelling is; this fact is utilized to prevent the bending of the wrapper tube, by making larger the cold working ratio for the part nearer to the middle of the reactor core where the quantity of neutron irradiation is large, than the part farther from the middle of the reactor core, on purpose to regulate the swelling of individual parts. The neutron flux has a radial gradient, higher in the middle of the reactor core and lower in the circumferential part, so that the planes 7a, 7b, of the wrapper tube 4 on the middle side of the reactor core receive larger quantity of the neutron irradiation than the opposite planes 8a, 8b. Accordingly, the cold working ratio for the material of the planes 7a, 7b, is made larger than that for the material of the planes 8a, 8b.

Filed: 1979-05-22
Abstract: PURPOSE: To manufacture a spheroidal graphite steel product having superior impact resistance, tensile strength and mechanical properties at a low cost by removing part of graphite contained in cast iron chips followed by sintering or powder forging.  
     CONSTITUTION: Lathe chips or the like of graphite flake-contg. cast iron such as gray cast iron are crushed with a hammer mill or the like, and free graphite contained is separated with a cyclone to reduce the C content to 1W2%. The resulting decarburized cast iron powder is suitably mixed with zinc stearate as a lubricant, pressure-molded in a metal mold under a molding pressure of 6 tons/cm 2  or more, sintered, and finish worked. In place of the sintering, presintering, heat forging and sintering may be carried out. By the heating to a high temp. just below the m.p. of the molding in the sintering process and the forging process and the following cooling, the residual graphite flakes are precipitated as spheroidal graphite or carbide, and graphitizing and spheroidizing of the carbide are facilitated by the pressure and heat in the forging. Since cast iron chips are used as starting material, and a spheroidizing agent such as Mg or Ca is not required, a spheroidal graphite steel product is obtd. at a low cost.
