Title: Zirconium-base alloy plate reduced in irradiation growth, its production, and its use
Inventor: INAGAKI MASATOSHI
IPC: G21C3/07
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of elongation and warpage deformation, caused by irradiation growth, by specifying the rate of orientation of a specific crystal orientation of hexagonal Zr of allot in a direction perpendicular to the plate surface. SOLUTION: Warpage deformation is caused by the orientation of the <0001> crystal orientation of hexagonal Zr metal in a direction perpendicular to the surface of Zr alloy. On neutron irradiation, the crystal is contracted in the <0001> direction and expands in a direction perpendicular to the <0001> direction. As a result, in the case of a fuel channel box in which the <0001> crystal orientation is oriented perpendicularly to the surface, irradiation growth occurs in a longitudinal direction and a width direction, If the amount of irradiation differs in different positions, difference in the amount of irradiation growth is bright about and causes warpage deformation. In this case, by regulating the rate of orientation, Fr as of the <0001> crystal orientation on a direction perpendicular to the plate surface is regulated to 0.20-0.50, irradiation elongation is remarkably decreased and, even in a high irradiation region of 10<22> (n/cm<2> ) amount of neutron irradiation, elongation is reduced essentially to zero, that is, the occurrence of warpage deformation can be prevented.

Title: Manufacturing semiconductor device
Inventor: TAGUCHI MINORU
IPC: H01L21/768
Filed: 1978-08-23
Abstract: PURPOSE: To prevent the disconnection of a base connecting portion by employing oxidization at lower temperatures than those for emitter slumping, forming an oxidized film relatively thicker than the one on other portions so as to improve the difference in level of the oxidized film on the Si substrate while removing by etching the oxidized fiom partly to which impurities have been added.  
     CONSTITUTION: An emitter layer 5 is made by diffusion from a doped layer 7 after providing two layers of SiO 2  6 and 7. The oxidizing speed on the surface of the emitter layer is considerably greater than that on the other low concentration portion if the layer is oxidized generally at a temperature lower than 900°C in high concentration, so that SiO 2  is formed thicker than that on the other portion because the diffusion of the layer 5 is suppressed. Simultaneously, the difference in level of the surface is improved, thus it is covered with SiO 2  6 and 7. After the doped layer 7 is made thinner by etching, using an HF liquid, the wiring of the base connecting portion will not be down because of little difference in level if the wiring 8 is then made by means of a selective opening.

Filed: 1979-08-09
Abstract: PURPOSE: To decrease the number of program steps by providing programmable logic array PLA that receives conditional flag contents and contents corresponding to program steps.  
     CONSTITUTION: Instruction decoder 4 sends program branch instruction JUM to PLA output part 11. Then, PLA8 receives respective bit contents of flag register 9 and step register 10 and generates the address of a program branch destination, determined in accordance with the combinational state of conditional flag contents, through logic constitution. Output part 11 performs OR in terms of respective output line signals of PLA8 and outputs the OR output as the address contents of the branch destination by instruction JUM. This output signal is supplied to address register 2 by way of multiplexer 7, completing branch processing. Therefore, the processing is performed by the single branch instruction and the number of program steps is decreased, which is useful for a microcomputer whose program size is limited.
