Title: Upper nozzle for nuclear fuel assembly
Inventor: HASEGAWA TAKAO
IPC: G21C3/33
Filed: 1990-03-05
Abstract: PURPOSE:To lessen probability of strength degrading and corrosion generating, and also to intend improvement of efficiency in the course of a manufacturing process by welding and fastening a lower side part and an upper side part which are formed previously and become a completed body when fastened together. CONSTITUTION:An upper nozzle 1 has a constitution where two parts of a conventional adapter plate 31, i.e. a lower part 2, and an upper part 3 are welded and fastened together. The upper part 3 is called an enclosure 3, too, and is cut out from an 80mm thick steel block by a mechanical processing. Also, for manufacturing the upper nozzle 1, the upper part 3 is welded to the adaptor plate 31 and the welded place is again welded and fastened together by utilizing an ordinary welding mean. After that, a completed body is obtained after final finishing, and, since only one place is welded during the process, thermal strain diminishes and a processing allowance in the final finishing process can be reduced in comparison with an ordinary example, and therefore processing efficiency can be much improved.

IPC: H01S3/098
Filed: 1985-03-19
Abstract: PURPOSE:To obtain a laser oscillator, which keeps condensing properties the same as a TEM00 mode and can maintain a laser output at a high value, by disposing an aperture (a mode selector) with an opening section narrow in the direction of flow of a gas and up to the width of flow of the gas in the direction orthogonal to the flow of the gas or the effective width of a mirror immediately before the resonator mirror. CONSTITUTION:Discharge electrodes 5 are arranged to the flow of a gas, glow discharge is generated among the electrodes 5, and resonator mirrors 1A, 1B are arranged at both ends of the electrodes 5. An aperture (a mode selector) 16 is disposed on one side of the resonator mirrors - that is, the end mirror 1A side in this case. An opening section for the aperture 16 is 19mm long in the direction of flow to the height of 50mm of a flow path and 44mm long in the direction of the height of the flow path, and beveling radii at four corners are 6mm long. Accordingly, condensing properties are approximately the same as a TEM00 mode on the smaller side of a beam diameter, and workability increases only by a section corresponding to the increase of a laser output when the smaller side of the beam diameter is directed in the progressive direction and does not lower so much on the larger side of the beam diameter in workability.

Abstract: PURPOSE:To perform processes in parallel by processors in point of time respectively, by providing a shared memory so that a read only state is introduced by the processor on one side, and a write only state, by the processor on the other side. CONSTITUTION:A processor 1, when sending a bit of information to a processor 2, writes the fact on a flag setting part 8 after writing the bit of information on a shared memory 7-1. The processor 2 reads the content of the setting part 8, and reads the bit of information in the memory 7-1 based on the content. Adversely, when the processor 2 sends out the bit of information to the processor 1, it writes the fact on the setting part 8 after writing the bit of information on a shared memory 7-2. The processor 1 writes the content of the setting part 8, and reads the bit of information based on the content. In this way, respective processor can perform the process in parallel in point of time.

Abstract: PURPOSE:To simplify the above structure by binding a housing to the end portion of a FRP member by a fastening member, driving a wedge spring between the housing and the FRP member in such a manner as to bite therebetween to press and fix both members, and firmly fixing a metallic end member to the FRP member. CONSTITUTION:The above suspension structure is constructed so that after a housing 12 is fixed to the end portion of a FRP arm 10 by a bolt 46 and a nut 47, a wedge spring 32 is driven and the wedge spring 32 is locked by caulking portions 41, 42. Thus, the arm 10 and the housing 12 are firmly fixed to each other, and liners 20, 30 function as a buffer material, so that the arm 10 and an end member 11 are kept from causing a relative motion such as rubbing against each other in the longitudinal direction. Accordingly, there is no problem that reinforcing fibers of the arm 10 are broken due to abrasion. Furthermore, it is enough to provide a small number of holes 45 on the arm 10 and the small inside diameter of the hole 45 can exhibit its function enough so that even if the holes 45 are bored, there is no problem in respect of strength.
