Title: Self-stop valve with liquid level detection air chamber and manual hose pump
Inventor: HATANO NAGAHIRO
IPC: F16K21/18
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent kerosene from overflowing from an oil tank in transferring kerosene by storing a valve having an air chamber and rockable by its tare weight in an upper tube and a lower tube fittable to the outlet side hose end of a manual hose pump, and installing a baffle plate above the valve. SOLUTION: A valve 1 having an air chamber 5 and rockable by its tare weight is stored in an upper tube 3 and a lower tube 2 fittable to the outlet side hose end of a manual hose pump, and a baffle plate 12 is installed above the valve 1. The air chamber 5 side of the valve 1 is set heavier in weight than the opposite side around a shaft 6, the valve 1 is tilted when kerosene flows in a pipe, and kerosene smoothly flows by the action of the baffle plate 12. When kerosene reaches the upper limit level of an oil tank, the air chamber 5 of the valve 1 is dipped in the oil surface, the tilted valve 1 is floated centering on the shaft 6 by the buoyancy of the air chamber 5, i.e., the valve 1 is closed, thereby the flow of kerosene can be automatically stopped.

Title: Impeller for use in air drawing and water lifting volute pump
Inventor: SUGIURA EIICHI
IPC: F04D31/00
Filed: 1981-07-29
Abstract: PURPOSE:To enable to lift water with a stable mixing ratio of air and water without causing separation of them, by forming fluid passages in an impeller in the manner that the inner wall surfaces of said fluid passages are parallel to axes extending perpendicularly to the axis of the impeller, and thereby reducing resistance of the fluid passages to the fluid flow and discharging fluid smoothly. CONSTITUTION:An impeller 1 is formed with many fluid passages 4 which are communicated to a fluid inlet port 3 formed concentrically with a driving shaft receiving hole 2 formed at the center of the impeller 1, in the manner that the fluid passages 4 extend radially outwards with uniform intervals in the circumferential direction and that the inner wall surfaces 5 of the fluid passages 4 are parallel to axes y extending perpendicularly to the axis x of rotation of the impeller 1. Since, by employing such as arrangement, resistance to the fluid flow through the fluid passages 4 is reduced as compared with that in conventional arrangements and fluid is discharged smoothly, separation of air and fluid is not caused while the fluid is passed through the fluid passages 4. Therefore, it is enabled to lift a fluid with a required air-fluid mixing ratio (for instance, 10- 20%) in a stable manner.

Title: Prime mover protector for generator
Inventor: SAKATA YASUO
IPC: H02J3/28
Filed: 1988-05-16
Abstract: PURPOSE:To eliminate upper and lower limit switches by operating differential effective power and frequency when the difference between a reference effective power and the effective power of a generator is higher than a predetermined level after confirmation of increase or decrease of bus frequency, and judging a faulty machine.
