Title: Zirconium alloy for nuclear reactor
Inventor: YASUDA TAKAYOSHI
IPC: G21C3/07
Filed: 1989-07-04
Abstract: PURPOSE:To manufacture a zirconium alloy having excellent corrosion resistance in a high temp-high pressure nuclear reactor by adding plural kinds of alloy elements having specified value of standard electrode potential, by the amt. exceeding the solid soln. limit, to pure zirconium. CONSTITUTION:Plural kinds of alloy elements having a standard electrode potential in the range of -0.5 to +1.5 volt are added, by the amt. exceeding the solid soln. limit, to pure zirconium. Furthermore, as the alloy elements to be added, 1.2 to 1.7% Sn, 0.07 to 0.20% Fe, 0.05 to 0.15% Cr and 0.05 to 0.15% Co are suitably regulated. Thus, by using the above zirconium alloy, the anode-dissolving amt. of the alloy elements to be added by a product from the radiolysis of water is reduced and the change of the formed oxidized film into a porous one is prevented, by which the nodular corrosion generated in a nuclear reactor can be prevented.

Filed: 1989-07-04
Abstract: PURPOSE:To increase the capacity of a luggage storing box and to stabilize the same so as to compensate for a lowering of rigidity due to an increase in size by a vehicle body frame by disposing a luggage storing box in such a manner as to extend from a lower frame upward and pass between both side frames to be over those frames, and holding the same on the lower frame and both side frames. CONSTITUTION:A vehicle body frame 10 includes a lower frame 14 a lower frame 14 which is dropped from a head pipe 12 and then extended obliquely to the upper back and a pair of right and left side frames 16 which are extended from the head pipe 12 backward and fixed to the lower frame 14, wherein a luggage storing box is disposed in such a manner as to extend upward from the lower frame 14 and pass between both side frames 16 to be over the frames, and fixed between the lower frame 14 and both side frames 16. By this arrangement, the luggage storing box 44 can be loaded stably and firmly while it is increased in size. Furthermore, as the bottom portion is held on the lower frame 14, and the side portions are held on both side frames 16, the lack of rigidity of the luggage storing box 44 itself can be compensated by the car body frame 10.

Title: Decoding circuit
Inventor: TAKADA MASAYUKI
IPC: H04H40/45
Filed: 1992-06-30
Abstract: PURPOSE:To improve the lateral decoding accuracy by using the error correction code added to each packet. CONSTITUTION:The packets are successively fetched by each frame buffer circuit 3 and at the same time a fact whether each lateral packet is corrected or not is decided by a lateral decoding operation. This deciding result is given to each packet and then the longitudinal codes of each packet are decoded. In this case, only the bit of the packet including a decoding error is corrected by the lateral decoding operation. Then a fact whether the lateral decoding is given to the packet having a decoding error and this error is corrected or not is decided by the first lateral decoding operation. In such a way, the lateral decoding accuracy is improved for a decoding circuit.

Title: Power steering gear
Inventor: SUZUKI AKIRA
IPC: B62D6/02
Filed: 1979-12-28
Abstract: PURPOSE: To enable the alteration of an input-to-output characteristic depending the speed of a vehicle even if its steering wheel is slowly operated, by providing a variable throttle valve between the hydraulic cylinder and control valve of an automobile power steering gear.  
     CONSTITUTION: Oil pressure from a pump is applied to a control valve 10 through an oil passage 23 so that a pressure difference is made between oil passages 25, 26 by a valve 12 operated by the driver, thereby actuating a hydraulic cylinder 37. When a hydraulic signal depending on the vehicle velocity or the like is transmitted to an oil chamber 30, the element 29 of a characteristic adjusting valve 27 provided between the control valve 10 and the hydraulic cylinder 37 is moved rightward to reduce the cross-sectional areas of orifices R 1 , R 2  in a passage connecting the control valve 10 and the hydraulic cylinder 37 to each other and open another orifice R 3  which is for connection between the right and left. As a result, an oil pressure difference acting to the hydraulic cylinder 37 becomes smaller than an oil pressure difference caused by the control valve 10, thus altering an input-to-output characteristic. Since the variable throttle valve is used for the alteration of the characteristic, always sure operation is attained.

Title: Adjusting circuit for lens stopping signal in automatic diaphragm control camera
Inventor: TAKAMI SATOSHI
IPC: G03B7/095
Filed: 1986-07-24
Abstract: PURPOSE:To certainly convert oscillating wave signals into pulses, by adjusting the gain of an amplifier which amplifies oscillating wave signals corresponding to lens stopping operations in response to the peak value of the amplified oscillating wave signals. CONSTITUTION:Firstly, microcomputer 31 is set to an initial adjusting mode by turning on a change-over switch SW. When a camera is released under such condition, oscillating wave signals S1 produced by a photo-chopper are inputted to an operational amplifier 24 and amplified oscillating wave signals S2 are produced. The computer 31 monitors the signals S2 and detects a peak value. Since the gain of the amplifier 24 is adjusted in a negative feedback state in corresponding to the peak value of the signals S2, the peak value becomes a fixed one which is almost equal to an expected value. The signals S2 which are peak-value adjusted in such way are sent to the computer after they are converted into pulses by a comparator 30 irrespectively of the excessively small and large states of the signals S1. The switch SW is made to open thereafter, but adjustment is performed by reading out these data, because these data are written in an E<2>PROM 34.
