Title: Differential pressure gauge
Inventor: UEDA MITSUO
IPC: G01L13/00
Filed: 1985-02-22
Abstract: PURPOSE:To measure even small differential pressure with high precision without being affected by the temperature of conductive fluid by measuring the differential pressure of the conductive fluid by utilizing electromagnetically induced force. CONSTITUTION:A communication pipe 6 is provided between the upstream-side high-pressure part 2a and downstream-side low-pressure part 2b of an orifice 2 and an electromagnetic flow meter and an electromagnetic brake 9 are interposed. When the fluid flows in the pipe 1, a pressure difference is generated across the orifice 2 and part of the fluid is diverted into the communication pipe 6. The velocity and rate of the diverted fluid are detected by the flow meter 7, whose signal is sent from an indication part 8 to a device 10. Then, the electromagnetic brake 9 is expected to intercept the flow of the fluid with the current sent through the device 10. Its braking force is proportional to the current supplied to the electromagnetic brake 9, so the current value is varied and read while the flow in the communication pipe is measured by the flow meter, and then the current in proportional to the braking force and the braking force is proportional to the differential pressure, which is found from the current value.

Title: Overflow prevention device for washing machine
Inventor: CHIYARUUUON RII
IPC: D06F39/08
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility that an error enters other than the installation positions, to accurately detect a water level and to surely prevent an overflow by installing a light receiving part and a light emitting part at a tube position equivalent to the scheduled water level position of a washing tank and detecting the water level. SOLUTION: In a washing process, a water supply valve is opened first and water supply inside the washing tank 100 is started. At the time, the light emitting element 103a of a water level detection part 103 receives a voltage supplied from a power supply terminal Vcc through a resistor R1 and radiates light to the side of an air tube 102. When the water supply is advanced and a fixed water level is reached, water is made to flow into the air tube 102 through an air chamber 101 proportionally to a water pressure inside the washing tank 100, and when the water level reaches the scheduled water level position 104, the output voltage of the water level detection part 103 is changed.  That is, since the quantity of the light reaching a light receiving element 103b becomes less, the light receiving element 103b becomes inoperative, a switching element Q1 is turned OFF and the water supply valve is closed.
