Abstract: PURPOSE: To protect the operators from a possible exposure to the radioactive rays in all the radioactive troubles that take place in the site of the nuclear power station, by isolating quickly the air conditioning system of the central control room from the ambient airs and preventing the radioactive substances from getting in directly to the inside of the room.  
     CONSTITUTION: When a trouble occurs involving the diffusion of the radioactive substances in the site of the nuclear power station, the radioactive substances diffused may move, depending on the direction of the wind, adjacent to the air intake 5 of the air conditioning system of the central control room. A radiological monitor 10 detects the radioactive rays of these radioactive substances, and inputs the accident signals of the radioactive level at the air intake 5 to the isolation switch 9 of the air conditioning system of the central control room with the intervention of the elecric cable 16. On receiving these signals, the switch 9 is put on and the isolation valve 6 and the blower 7 are resoectively closed and suspended for emergency. And if the accident signals are generated directly at the spot where the accident takes place, the signals are input directly to the switch 9 to isolate the air conditioning system of the central control room likewise.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the ground surface from freezing very economically and surely by burying a sheet body containing granules or powder of far infrared radiation body under the ground in nearly parallel with the ground surface. SOLUTION: A sheet body 3 is formed out of a sheet base material in which granules or powder of far infrared radiation body 4 such as ceramics or alumina are mixed in a sheet base material such as synthetic resin or rubber, into a sheet of fixed thickness and width. This sheet body 3 is buried in a fixed range from the outer surface of a pavement material 1 or a lawn in the condition of one layer or spacedly 2-3 layers. A heat flux is always let flow toward the ground surface by temperature gradient under the ground, and when the heat flux us passed through the sheet body 3, the far infrared radiation body 4 in the sheet body 3 absorbs the major part so as to radiate the far infrared rays, and hence freezing on the ground surface can be surely prevented.

Abstract: PURPOSE:To enhance detecting accuracy by comparing a detected steering angle and an estimated steering angle which are detected by the completely different means of a steering-angle detecting means and a vehicle-speed detecting means, detecting the error in either angle and detecting the error when the difference has continued for a specified time period. CONSTITUTION:At first a register and a memory are initialized by supplying a power source. The output values of a steering angle sensor 2 are counted in a counter 3. Operation is performed in an input/output part 8f in an electronic control device. Thus, the steering angle is obtained. The wheel speed of each wheel is obtained from wheel speed sensors 4 - 7. The speeds of the right and left idler wheels are used, and the steering angle of a vehicle is estimated and operated based on the geometrical model at the time of turning, and the estimated steering angle is obtained. Then, the neutral steering angle is obtained, and the detected angle is corrected to the value from the neutral angle. The value is compared with the estimated steering angle, and the abnormality in steering angle is judged. This operation is repeated, and the corrected detected steering angle is utilized for anti-skid control.

Abstract: PURPOSE:To eliminate the need for a separate water-controlling gate by a method in which the upper rectifying plate of an intake board is separated into the central part and an outer annular part to form a water-controlling gate, and the inlet of the upper end of a cylinder is opened or closed by vertically moving the central part and the outer annular part. CONSTITUTION:An intake board 2 is provided to the upper end of a multi-stage cylinder 1, and water is taken in from a port 2a and discharged from a water conveyance tube 3 on the bottom in a cylinder gate equipment. In such a cylinder gate equipment, the upper rectifying plate 4 of the intake board 2 is separated into central part 4a and outer annular part 4b to form a water-controlling gate A. In usual water intake, the central part 4a and the outer annular part 4b are worked in the form of an integrally combined upper rectifying plate 4.
