Title: Non-critical control method of reactor fuel
Inventor: ODA MASASHI
IPC: G21C17/06
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To perform critical evaluation of the inside of a system with a simple device configuration, by measuring the distribution of neutron flux in a diameter direction in the system in the loaded process or storage state of each reactor fuel assembly, and judging to see if the increase rate of the neutron flux from the peripheral part of an already loaded region to a central part has exceeded a set tolerance or not. SOLUTION: A neutron detector 9 is installed at an important position in a fuel assembly accommodation rack being installed in a pool to measure the distribution of neutron flux in the diameter direction of the loading system of an assembly 1. On the other hand, a possibility where a neutron being generated in the assembly 1 exceeds a chain reaction increases, the ratio of neutrons leaking to the outside of the system increases, and the neutron flux distribution is maximized near the center of the system for indicating a projection distribution. The difference in the distribution is judged by the count rate distribution of a neutron detector 2.  With the installation interval of the detector 2, two detectors 2 are preferably installed at positions that are not equivalent in terms of a critical evaluation so that the reduction in the degree of non-criticalness due to the erroneous loading of a fuel can be detected.

Title: Pilot valve
Inventor: NISHIZAWA AKIZUMI
IPC: F16K31/524
Filed: 1993-12-28
Abstract: PURPOSE:To prevent irregular outputs of a pilot valve by providing a throttle hole linked with the inside of a cylinder chamber in a sleeve with a bottom for receiving the piston of a pushing rod and providing a spring between this hole and the piston. CONSTITUTION:In a case where an output is made from one side pressure reducing valve, the pushing rod 68 of the other side pressure reducing valve is energized upward by a spring 78 elastically provided between the pushing rod 68 and a sleeve 74 with a bottom. When, for instance a lever is suddenly released from this state, an operating part presses the pushing rod 68 of the other pressure reducing valve beyond a neutral position by the inertial force, etc., of the lever. Then, the piston part 72 of the pushing rod 68 is moved downward in the bottomed sleeve 74. At this time, the movement of the piston part 72 is limited by resistance generated when oil filled in the sleeve 74 passes through a throttle hole 76 provided therein and the resistance of the spring 78. Thus, the generation of the irredular outputs of the pilot valve can be prevented.

Filed: 1989-12-26
Abstract: PURPOSE:To suppress deviation of a driving voltage based on an early effect of a transistor in a comparing voltage forming circuit by applying the output of a voltage booster to the forming circuit to depend a comparing voltage upon a first power source voltage. CONSTITUTION:When a power source voltage VS is applied to the base of a control transistor Q31, a voltage of the voltage VS=VS+2VD (VD: forward voltage of diodes D1, D2) is output from the emitter of an output transistor Q32. The voltage VS depends upon the voltage VS without depending upon a power source voltage VCC, and is set to a voltage always higher by 2VD than the voltage VS. Accordingly, the voltage VS is applied to an input terminal IN to suppress an early effect of transistors Q2, Q4, Q12, Q14, Q22, Q24 to output suitable driving voltages U, V, W. As a result, a motor performs normal rotation.
