Patent JP-H0356899-A (JP)
Title: Emergency shutdown device of fast breeder
Inventor: HASHIGUCHI ISAO
IPC: G21C7/14
Filed: 1989-07-25
Abstract: PURPOSE:To allow the operation of a scram even when the temp. of a coolant rises abnormally to the temp. below the Curie point by housing a thermal expander into a control rod extension pipe in such a manner that the control rod can be pressed when the expander expands thermally. CONSTITUTION:The coolant 2a which flows into a coolant introducing pipe 4 from a control rod assembly guide pipe 13 and flows fast at a high temp. and the coolant 2b which flows into the coolant introducing pipe 4 form a control rod lower guide pipe 12 and flows slow at a low temp. move into and out of a vessel 22 through a coolant outflow/inflow port 21 even if the coolants are, for example, not mixed well with each other. The thermal expander 24, therefore, expands thermally when the temp. of the coolant 2a rises abnormally. Whereas, the thermal expander is held fixed by a protective pipe 23 and a screw 25 and, therefore, the expansions heads toward the lower direction only. The control rod 7 is thereby pressed and a gap is generated between the control rod extension pipe 5 and the control rod 7. The leak magnetic flux of the electromagnet at the Curie point increases and the traction force of the control rod 7 weakens. The control rod 7 is thus dropped and inserted into the core. The control rod scrams even if the temp. of the coolant around the electromagnet 6 at the Curie point does not attain the temp. above the Curie point when the temp. of the coolant 2a rises abnormally.

Title: Reinforcement protective system against transient excessive output
Inventor: YUUJIN CHIYAARUZU ETSUKAATO
IPC: G21D3/12
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To enhance protection against transient overoutput by automatically adjusting the trip set value for preventing overoutput of reactor higher, by a predetermined amount, than the operational output level of a boiling water reactor(BWR). SOLUTION: A follow-up scram set value theory circuit 12 and a follow-up alarm set value theory circuit 14 increase the scram set value and alarm set value automatically upon scheduled increase of output thus sustaining a desired trip margin. The set values are used by a scram trip unit 16 and an alarm trip unit 18 for monitoring the simulated output signal from a signal filter 20. Scram of reactor can be started based on a scram signal from a scram trip unit 16 or a high output trip unit 22. Variation of output is recognized based on an allowable input signal and since the follow-up logic circuit can increase the set value only when it is especially controlled for that purpose, enhanced protection can be attained upon occurrence of an unscheduled increase of output takes place. Adjustment of set value lowers the output and realizes automatic follow-up.

Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a reverser for a water jet propulsion unit generating no turbulence for the reversion of an injection stream with the same handle operation for forward rotation and reverse rotation. SOLUTION: The upper wall face 14b and the rear wall face 14c of a reverser 14 reversing the advance direction of a ship are formed into a curved surface, and the lower face section 14d is expanded. The angle of the side wall face 14e of the reverser 14 against the center line of a discharge casing 7 is made larger than the maximum rudder angle of a deflector, and the cross sectional shape of the reverser 14 is made a fan shape. The collision of the injected stream from the deflector with the side wall face 14e is resolved, the injected stream is reversed in the right and left opposite directions, and the operation performance at the time of reverse rotation is improved.

Title: Magnetic head and its production
Inventor: TANAKA YASUO
IPC: G11B5/265
Filed: 1985-08-29
Abstract: PURPOSE:To decrease the magneto-resistance and to increase the mechanical strength of magnetic cores as well as the adhesion intensity between magnetic cores, by forming the stage parts at the both sides of both magnetic cores for record/reproduction and erasion with the prescribed depth from the side of a slide contacting surface. CONSTITUTION:A magnetic core 21 for record/reproduction contains a record/ reproduction gap 21g and a magnetic core 22 for erasion has erasion gaps 22ga and 22gb. The surfaces of both cores 21 ad 22 form a slide contacting surface 29 to a magnetic recording medium. Then the track width setting grooves are formed at the both sides of the surface 29 in its lengthwise direction. Thus the track width of a magnetic head is set. These grooves produce the stage parts 31 and 32 and a nonmagnetic material 23 is filed into both parts 31 and 32. Therefore the track of the magnetic head is prescribed by the width between both parts 31 and 32.

When the door is closed, the member 12 moving reciprocally contacts the vertical frame of the door frame 110 and is pushed in the door body 101, and the plate spring 125 is bent to push down the gap-shielding member 130 and protrude the end thereof from the bottom of the door body 101. In this time, the gap-shielding member 130 is pressed on the upper face 112 of tread made of an electric conductive material and a part of the container room 102. The whole opening of door frame 110 is sealed with an electric conductive member to be electromagnetically shielded. And hence, the face of tread can be made flat and made flush therewith.

IPC: B62D7/14
Filed: 1989-07-24
Abstract: PURPOSE:To set the hydraulic equipment of a hydraulic system to a proper value by providing two centering springs opposite to each other, and mutually differing in the set loads of the centering springs. CONSTITUTION:A centering spring 73 is formed out of two left and right centering springs 73A and 73B. Thus, when the input loads entering left and right tie rods 21, 21 are different, resulting from the layout of a vehicle, for example, differences in length of constituting members of a rear suspension and mounting position of coil springs, the spring rates of the centering springs 73A, 73B are mutually different corresponding to the respective input loads, whereby the unbalance in input loads is absorbed and removed. Consequently, when the hydraulic assist force of a power cylinder 46 is lost, the left and right tie rode 21, 21 and the rear wheels are certainly spring-energized to the center position by the springs 73A, 73B. Further, the loads of the springs 73A, 73B can be easily set, and the energization of an excess oil pressure to the hydraulic system is not required.
