Title: Semiconductor memory device
Inventor: RYU YASUSHI
IPC: G11C29/04
Filed: 1989-02-09
Abstract: PURPOSE:To simplify constitution, to reduce a chip area, and to attain high integration by storing the address of a row or column including a defective cell as a defective address, and also, storing a direction of relief. CONSTITUTION:Data is fixed at a masking ROM 41, and it is read out and inspected. When a defect exists in a memory cell 20, the address of the row or column including the defective cell is stored in a defective address storage cell 45, and information to designate the direction of relief is stored in a relief direction storage cell 44. Then, the data to be written on a cell of one row including the defective cell is written on a redundant cell 32. When an external address is inputted, the address of the row or column is selected by an address conversion circuit 43 based on the information from the cell 44, and it is com pared with the address of the cell 45 at an address comparator 46. When those addresses coincide, the data of the cell 32 is read out via redundant row and column decoders 28 and 31, then, substituted. Thereby, only one comparator is enough, and the constitution can be simplified, and the chip area is reduced, which attains the high integration.

Title: Sodium leakage detector
Inventor: FURUMURA SHIROU
IPC: G01N27/411
Filed: 1981-03-05
Abstract: PURPOSE:To detect the leakage of cooling sodium for a high speed breeder quickly positively by using a sodium detection element comprising a combination of a solid electrolyte and an electrode element. CONSTITUTION:For double piping in the primary system of a high speed breeder, an electrode element (sulfur, for instance) 5 is attached to the inside surface of an external pipe 6 and a solid electrolyte (beta-alumina comprising Al2O3, Na2O and Li2O, for instance) allowing sodium to selectively transmit onto the above surface is connected to the external pipe in order to form a detection element. When damage is caused in an internal pipe 2, liquid sodium 1 flowing in the pipe flows into a space 3 between the internal and external pipes 2, 6, an inactive gas being permitted to flow in the space 3. The liquid sodium subsequently comes in contact with the solid electrolyte 7 and ionized sodium passes  through the solid electrolyte 7, reaching the electrode element 5 to react in the manner given by formula. As a result, potential is caused to be generated, whereas the potential is read by an potentiometer 10 via electrode leader lines 8, 9 to detect the leakage of the sodium.

Title: Welding method for metallic body
Inventor: TADA KAZUO
IPC: B23K11/16
Filed: 1978-03-16
Abstract: PURPOSE:To make weldable the metallic body independently of the thickness of dielectric oxide film, and to stabilize the weld strength, in the case that the metallic body is welded to another metallic body whose surface is oxidized to be an insulator, by forming a layer of conductive substance over the outer surface of the surface- oxidized metallic body. CONSTITUTION:The conductive substance 4 like as the conductive adhesives is applied over the periphery of the dielectric oxide film 2. Then, when the outgoing line 3 is to be welded by the resistance welding, the welding current, supplied from the upper electrode 5 of the resistance welder, flows through the conductive substance 4. The contact point, between the metallic outgoing line 1 and outgoing line 3, generates a heat due to this current flowing through the conductive substance 4; also, the dielectric oxide film 2 is destructed by this heat, so that the metallic outgoing line 1 and the outgoing line 3 are perfectly welded. According to this method, can be obtained the weld strength equivalent to the welding in the case that the dielectric oxide film does not exist.

Abstract: PURPOSE:To obtain a sample of high quality without the mixing of any air bubble by elevating a pendulum base and pressing cover glass from above its top surface at an eccentric position on the top surface of the pendulum base by a pressing member end part under specific pressure. CONSTITUTION:Slide glass 110 is elevated from a conveyance path 210 by the pendulum base 613 and one end part of the glass 110 contacts an edge part of the cover glass 518. In this state, a motor is stopped and this state is held awhile. Simultaneously, a liquid adhesive 480A is spread between the glass 110 and glass 518. Then, the supply of vacuum pressure to a suction board 552 is stopped to superpose the glass 518 upon the glass 110. Then, the pendulum base 613 is elevated, and while the holding base for the glass 110 is returned from inclination to the level state at the eccentric position on the top surface of the pendulum base by the pressing member 560, the glass 518 is pressed against the glass 110 under nearly the same pressure. Consequently, the sample of high quality is obtained without any air bubbles in the sample.
