Title: Connection structure between control rod driving housing and nuclear reactor pressure container
Inventor: ASANO MASAYUKI
IPC: G21C13/00
Filed: 1989-02-22
Abstract: PURPOSE:To improve the reliability of the SCC (stress corrosion cracking) resistance of the joint part between the control rod driving (CRD) housing and pressure container by reducing the cicumference-directional heat stress of the weld zone of the CRD housing and a stub tube. CONSTITUTION:At the joint part between the CRD housing 3 and nuclear reactor pressure container 1, a groove is cut at the upper part of the stub tube 2 welded to the bottom plate of the container 1, the housing 3 is inserted into the tube 2 and positioned, and then weld metal is built up at the groove part to the level of the upper part of the tube, thereby welding the housing 3 and tube 2 together. In this joining operation, the circumference-direction tension heat stress generated at the contacting part with the housing 3 at the weld zone owing to the heat expansion difference between the housing 3 and tube 2 in nuclear reactor operation is reduced greatly by the clamping effect of the tube 2 occupying the outer periphery of the weld zone. Therefore, the possibility of the generation of the SCC at the weld zone in the container 1 decreases greatly to eliminate a serious accident due to the leak of reactor water.

Title: Absolute linear position detector
Inventor: SHIMIZU WATARU
IPC: G01D5/245
Filed: 1991-02-12
Abstract: PURPOSE:To enlarge a detection range by providing a calculating means which calculates difference in position detection signals from first and second linear sensors, determines periodicity of the first linear sensor from an origin of an object to be detected and outputs periodicity signals. CONSTITUTION:When mechanical displacement amounts of an object to be detected are P1, P2, respectively, linear sensors S1, S2 output signals N1, N2 of one period. Then when the object moves by P1 from the origin, the outputs of the sensors S1,S2 are N1, (N2.P1)P2. Therefore output signals D1, D2 of the sensors S1, S2 with respect to the current position of the object are D1=N1, D2=(N2.P1)/P2 at an absolute position P1 and input to a calculator COM. In the calculator COM, periodicity Cx of the signal D1 of the sensor S1 is obtained as difference in outputs D12 from the sensors S1, S2=D1-D2 by Cx=D12/(N1.P2- N2.P1)/P2. Then by combining an integer part of the periodicity Cx and the signal D1, a linear position of the object can be absolutely specified.

Title: Simple estimating method for joint rigidity/deformation of structural member
Inventor: FUJIWARA AKIFUMI
IPC: B62D25/00
Filed: 1998-02-07
Abstract: PROBLEM TO BE SOLVED: To evaluate the application possibility of a beam model by estimating local rigidity of the joint part by regarding the total of rigidity of a panel as the local rigidity by finding flexural rigidity of a main pipe flange surface-substituted virtual rectangular panel by a beam theory and a band plate theory. SOLUTION: A branch pipe having a rectangular cross section estimates local rigidity and deformation of the joint part of a structural member installed on the flange surface of a larger hollow main pipe. For example, a branch pipe having a cross section of (2a×2b) is vertically installed on the flange surface of the main pipe having a width 2W as a T-joint of mutual rectangular cross-sectional members. Since out-of- plane bending, in-plane bending and axial tension act on this branch pipe, when the out-of-plane bending acts, it is supposed that the branch pipe is put in a supporting state by a virtual rectangular panel. A boundary condition of the virtual rectangular panel is supposed. Next, rigidity of the flange surface at out-of-plane bending acting time is found by a simple estimating expression.  Therefore, the whole can be analyzed by a beam model by addition of a spring corresponding to local deformation by evaluating the application possibility of the beam model to estimate rigidity of the whole frame structure such as an automobile.

Title: Method and apparatus for controlling defective-board mask detection in automatic electronic component mounting machine
Inventor: ITO TAKASHI
IPC: B23P21/00
Filed: 1989-02-21
Abstract: PURPOSE:To surely execute a control operation by a method wherein a result of a defective-board mask detection operation is judged according to storage contents corresponding to a plurality of groups into which a board has been divided and a mounting step is not executed and is skipped at a defective board. CONSTITUTION:A mounting program 2 is read out via a data reader or a floppy input/output device and is stored in a mounting program memory 5. A program analysis part 6 started by a main control part 7 by means of a machine seizing signal ST from an operator reads out a data covering one step from the mounting program memory 5 and analyzes it. Then, the program analysis part 6 analyzes the one-step data and investigates whether a defective-board mask detection command exists or not. When the defective-board mask detection command exists, a defective-board mask detection cycle is executed; when the defective-board mask detection command does not exist, a normal electronic- component mounting operation is executed. Accordingly, it is possible to avoid that an electronic component is mounted on a defective board. Thereby, the electronic component is not wasted; productivity is enhanced.
