Title: Water supply controller
Inventor: YOSHIDA TAKAO
IPC: E03C1/05
Filed: 1992-03-02
Abstract: PURPOSE:To shorten a response time required for sensing a user by flood-light ing a plurality of pulses at every flood period and repeating pulse floodlighting until reflected light in the fixed number of sensing decision is obtained when reflected light is detected. CONSTITUTION:A sensing confirming means composed of a flood-pulse generating circuit 42 and a sensing confirming circuit 6 is constituted to a water supply controller 1 using a reflection type sensor 2, in which the reflection signal of a signal intermittently transmitted from a floodlighting section 4 is detected by a light-receiving section 5 and a user is sensed. A preset number of pulses are transmitted at regular time intervals. When the reflection signal is detected by the light-receiving section 5, pulse transmission is repeated until the reflection signal in the preset number of sensing decision is detected within the range of preset maximum delivery number of pulses when the number of the detected pulses is smaller than the number of pulses transmitted. Accordingly, the accuracy of detection can be improved at every flood period.

Title: Plate valve
Inventor: JINNO YUKISHIGE
IPC: F16K3/02
Filed: 1981-05-29
Abstract: PURPOSE:To reduce the wear of valve seats and seal plates of a valve plate by coupling an electromagnet to a valve plate as one body and also by providing a seal plate to each face of a valve plate, facing the inlet or outlet port of the valve, in such a manner that the seal plates can be moved in the direction of the fluid flow. CONSTITUTION:When a coil of an electromagnet 11 is electrified to positive while a valve plate 6 moves vertically, seal plates 10a and 10b attached to the valve plate 6 move outward on account of attractive force by the electromagnet 11 in order to be housed in recessed parts 6a and 6b of the valve plate 6. And gaps between valve seats, 3a and 3b, and the seal plates, 10a and 10b, become large. Accordingly, the speed of slurry, for example, passing through each gap is lowered. It prevents fine solid bodies from being caught in the gap between the valve seats, 3a and 3b, and the seal plates, 10a and 10b, and reduces the wear of the said valve seats and seal plates.

Title: Temperature adjusting method for humidifier with ambient temperature
Inventor: TEI YU
IPC: F24F6/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To keep spray temperature unchanged by lowering/raising the temperature of water in a humidifying tank with ambient temperature by controlling on/off operation of a heater for heating water in the humidifying tank based upon a comparison result of temperature of the humidifying tank with temperature set for cold humidifying mode. SOLUTION: When there is a switching input to a cooling/humidifying mode, a detected present humidity is compared with an arbitrary set comfortable humidity (S10). Provided the comfortable set humidity is higher than the preset humidity, temperature in a humidifying tank is detected, and the detected temperature of the humidifying tank is compared with the comfortable cooling/ humidifying temperature (S12). Provided the temperature of the humidifying tank is higher than the comfortable cooling/humidifying temperature, operation of the heater is interrupted (S13). However, provided the temperature in the humidifying tank is lower than the comfortable cooling/humidifying temperature, the heater is turned on (S14). Provided the temperature of the humidifying tank is higher, the heater is controlled to keep its on state, and a fan/a vibrator is also controlled in the on state (S15).

Abstract: PURPOSE:To enable a device to travel automatically inside a curved pipe by allowing the device to repeat a looper like motion where the device includes a rotor which changes over a driving power source, numbers of feet which expand and contract to the circumferential direction of a pipe, and an expansion body which expands and contracts to the axial direction of the pipe. CONSTITUTION:A rotor 4 of a change-over valve 103 is rotated as a result of rotation of a motor 101 through a reduction gear 102 allowing air from an air line 19 to be switched over. This causes a rubber bag 8 to be inflated allowing it to contact closely to the inner surface of a pipe 499. Then, a bellows 110 is expanded permitting its foot 105 to move to the position of a foot 105A. Then, a rubber 6 of the foot 105A is inflated allowing it to contact closely to the inner surface of the pipe 499, then, air is discharged from both the rubber bag 8 and the bellows 110. In this case, the bellows 110 is contracted by a force of a coiled spring contained allowing a group of foot 107, the change-over valve 103 and the motor 101 to be advanced. As this configuration enables this device to travel automatically inside a long pipe of a small diameter, even if it is curved, by repeating a looper like motion. Thus, this device enables operations such as inspection and the like to be easily performed.
