Title: Positioning device and handling jig
Inventor: NISHIKAWA MASASHI
IPC: B23Q3/18
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To heighten the contact performance of a receiving piece with an abutted surface of a work in a positioning device. SOLUTION: A shaft body 18 and a guide part 19 are supported in a floating manner on a main body 11 by an elastic body 21. A receiving piece 9 is fitted through a ball joint 10 to the guide part 19. When the receiving piece 9 is butted against a work W, the receiving piece 9 is rotated around a contact point 9b with a surface W, to be abutted. At this time, the center point 10c of the ball joint which is the actual rotational center point of the receiving piece 9 is moved with respect to the original axis. Accordingly, the angle of the contact surface 9a of the receiving piece 9 is coincided with the surface Wf to be abutted without excessive force applied to the contact point 9b of the receiving piece, the surface Wf to be abutted of the work, and the ball joint 10.  Further, the conical surface 19a of the guide part 19 is guided to slide on the conical surface 11b of the main body 11. Thus, the position of the ball joint 10c moved from the original axis is corrected, and the conical surfaces 11b, 19a come into close contact with each other to eliminate the floating state of the shaft body 18 to the main body 11.

Title: Self-operation type reactor shut-down mechanism
Inventor: SAITO MAKOTO
IPC: G21C9/02
Filed: 1989-03-17
Abstract: PURPOSE:To improve the response performance on the generation of abnormality by constituting the mechanism in such a manner that the upper part of the wall of a wrapper tube adjacent to a control rod insertion part consists of a temp. sensitive magnetic material and constitutes a part of the magnetic circuit of an electromagnet. CONSTITUTION:The upper part (the part of the range where the electromagnet 14 moves vertically) of the wrapper tube 18 of an adjacent fuel assembly 16 is constituted of the temp. sensitive magnetic material 30 by which the saturation magnetic flux density decreases when the temp. of a coolant rises abnormally. The magnet 14 has an iron core and armature which can be coupled and separated above and below as well as a coil wound on the iron core. This magnet is constituted by incorporating a nonmagnetic material to the point in proximity to the material 30. A control rod 10 is held by the electromagnet 14. The magnetic circuit is shut off and the control rod 10 falls to be inserted into the reactor when the temp. of the coolant is risen by the generation of the abnormality in the assembly 16 to exceed the Curie point of the material 30. The reactor is then shut down. Resetting is executed by descending the main part of the magnet 14 to the top end of the control rod 10, magnetically attracting the armature in this position to hold the control rod 10, and installing the control rod to a prescribed position by pulling up the rod 10 by a driving shaft 28.
