Title: Measurement of flow rate at core of neuclear reactor
Inventor: TAKAYAMA YOSHITO
IPC: G01F1/00
Filed: 1981-03-30
Abstract: PURPOSE:To detect always correct flow for measurement of the flow at a core by a method wherein a back-current computing circuit is switched over by detecting the back-current via one pump, the trip signal, the supporting plate pressure difference signal and the flow signal. CONSTITUTION:When one of two recycling pumps 6 of a boiling water type nuclear reactor 1 is tripped, the normal loop and the tripped loop are identified by an identifying circuit 12. The difference of the coolant pressures at a supporting plate 2a of a core 2 between inside and outside of the core is measured by a pressure difference oscillator 14 and the measured value is divided by the total flow of an adder 6a by a divider 15. When the divided value is judged to be more than the allowable value, the generation of the back-current at one of jet pumps 3 is detected and the flow signals 8 and 9 are switched from the adder 6a to a subtracter 11. The back-current can be properly detected and the computing circuit can be switched over, so that the correct flow at the care can be detected even when one of the recycling pumps 6 is stopped.

IPC: B30B13/00
Filed: 1992-03-04
Abstract: PURPOSE:To enable changing the setting value of over-load and to contrive the protection from the over-load by connecting a relief pressure changing means capable of changing the relief pressure of a relief valve for getting away pressurizing fluid from a hydraulic chamber in a hydraulic cylinder to the relief valve. CONSTITUTION:At the time of starting the operation of a pressing machine, in the case foreign material interferes a feeding bar and the movement of forwarding/retreating of the feeding bar is obstructed, a cylinder body 50A in an air cylinder 50 ascends to a piston rod 50B. That is, the piston rod 50B is relatively worked to extend to the cylinder body 50A, and the air pressure in an air pressure chamber 51 is increased. When the air pressure becomes larger than the relief pressure set in the relief valve 54, since the relief valve 54 is worked, the air in the air pressure chamber 51 is got away from the relief valve 54 through an air getting-away circuit 55. By this method, the cylinder body 50A can freely be moved to the piston rod 50B and the breakage caused by the over-load to the constitution parts can be prevented.

Title: Colloid-type lead storage battery
Inventor: YONEZU KUNIO
IPC: H01M10/10
Filed: 1979-04-17
Abstract: PURPOSE:To prevent the electrolyte from decreasing in specific gravity during discharge and to prevent abnormal voltage from occurring during charging, by adding hollow glass short fibers to a colloid electrolyte. CONSTITUTION:Hollow glass short fibers are added to an electrolyte of dilute sulfuric acid gelled with silicic anhydride. The hollow glass fibers hold the electrolyte therein because of their capillary action. The electrolyte held inside the glass fibers do not diffuse easily because of the high affinity with glass. The sulfuric acid in the glass fibers does not contribute to discharge but diffuses gradually to the surrounding dilute sulfuric acid when discharge continues. Because of this replenishment of sulfuric acid to the electrolyte, it is possible to prevent the electrolyte from decreasing in specific gravity during discharge and to prevent abnormal voltage from occurring during charging.

Abstract: PURPOSE:To reduce the dimension of a sealed-type compressor by using a full eccentric type crank shaft and projecting the edge part, on the sliding contact surface side, of a crank shaft part of a main bearing, to the cylinder side from the cylinder installation surface of a supporting frame. CONSTITUTION:A full eccentric-type crank shaft 33 having the shaft center O' at the eccentric position departed by a prescribed distance epsilon from the position of the shaft core of a rotary shaft 31 for advancing and retreating a piston 27 is installed onto the rotary shaft 31. Therefore, the length of the rotary shaft 31 can be reduced. The edge part on the sliding contact surface side making contact with the crank shaft part 33 of a main bearing 32 installed onto a supporting frame 22 is projected to the cylinder 26 side from the cylinder installation surface of the supporting frame 22.

Title: Gas filter
Inventor: KATSUMOTO MASAYUKI
IPC: C01B32/40
Filed: 1987-03-04
Abstract: PURPOSE:A gas filter, obtained by preparing tin oxide under specific condition, capable of burning combustible gases other than CO in a mixed gas of CO- containing combustible gases with O2-containing gas to permeate the CO in an unburned state and useful as a CO sensor. CONSTITUTION:A catalyst containing stannous oxide and stannic oxide is prepared and the resultant powder is filled in a thin cylinder 2 having two opened ends covered with silica cloth to give a filter 1, which is kept at, e.g. 350 deg.C. A mixed gas of CO and combustible gases other than CO, particularly H2, etc., and a gas containing O2 sufficient to burn the at least the combustible gases other than the CO, e.g. air, is flowed from one opened end. Since the tin oxide has a much higher activity of oxidizing H2 than that of oxidizing CO, the combustible gases other than the CO are burned and the CO is permeated in the unburned state. Thereby the filter 1 can be placed before a commercially available gas sensor 3 to provide a CO sensor.
