Title: Wireless travel amount sensor
Inventor: SHIYOUKAKU AKIROU
IPC: G01B7/00
Filed: 1991-03-05
Abstract: PURPOSE:To extend the damping time of an echo, to keep a detection frequency constant, and to improve the detecting precision of the echo by using a resonator in a sensor part. CONSTITUTION:When a change-over switch 3 is connected to (a) side, an electromagnetic wave from an oscillation part 4 is sent to an antenna 2 for transmission/reception via the change-over switch 3, and resonance occur in sensor parts 1,1', and 1n' by electromagnetic coupling, and energy is accumulated in a circuit. Since the oscillation part 4 transmits the electromagnetic wave intermittently, the sensor parts 1,1', and 1n' discharge the energy gradually when the electromagnetic wave is stopped, and a voltage is induced at the antenna 2 for transmission/reception by mutual induction due to the energy. In such a case, a control part 6 connects the change-over switch 3 to (b) side, and the electromagnetic wave induced at the antenna 2 for transmission/ reception is sent to a reception and monitoring part 5 via the change-over switch 3. The reception and monitoring part 5 identifies the size of a detected signal setting as information.

Abstract: PURPOSE:To selectively transmit and concentrate a volatile org. liquid component, by using a dry hydrophobic porous membrane wherein the ratio of an average fine pore radius and the Stokes radius of a substance to be separated is a specific value or more and the average fine pore radius is a specific value or less and setting a secondary side to a low temp. and low pressure condition. CONSTITUTION:For example, a membrane module 4 is formed by using a dry hollow yarn membrane obtained by a method wherein a raw spinning solution prepared from polyvinylidene fluoride and a solvent such as dimethylsulfoxide is spun from a die to be coagulated in water and washed to obtain a hollow yarn in a hydrated ate while water contained in the membrane is substituted with n-hexane through methanol before the drying of the membrane in air. A volatile org. liquid aqueous solution such as an aqueous ethanol solution held to relatively high temp. by a heat exchanger 3 is supplied and recirculated from a supply tank 1 to the primary side of the membrane and the secondary side of the membrane is held to temp. and pressure lower than that of the primary side by a heat exchanger 6 and a reduced pressure control needle valve 7. A volatile org. liquid component such as ethanol selectively transmits through the membrane to be conc. in the secondary side.

Title: Combination faucet
Inventor: SUZUKI SHIGERU
IPC: F16K11/06
Filed: 1986-02-24
Abstract: PURPOSE:To increase and decrease the hot water flow rate accurately in proportion to the increase and decrease of the opening amount of a hot water inlet hole so as to eliminate fluctuation of a set temperature of hot water and thereby to provide hot water at a stable temperature at all time by providing pressure relief means for hydraulic pressure so as to prevent application of high hydraulic pressure to the hot water inlet hole. CONSTITUTION:When a handle is operated to effect a rotation A of a valve shaft 1b, a valve member 9 is slidingly moved in a first direction X through a pinion 5 and a rack so as to regulate the registered amount between a cold water inlet opening 6 and a cold water inlet hole 11 and the registered amount between a hot water inlet opening 7 and a hot water inlet hole 12. When the handle is operated to effect a swing B of the valve shaft 1b in the front-to-back direction, the valve member 9 is slidingly moved in a second direction Y, so that, with these registered amounts maintained, the respective opening amounts are regulated. Cold and hot water respectively from the cold water inlet hole 6 and the hot water inlet hole 12 flows out through a communication chamber into a mixing chamber. At this time, water flows into the mixing chamber also through pressure relief windows 8b opening in a communication chamber defining wall 8a of a valve seat support 80. This effectively prevents application of high hydraulic pressure to the hot water inlet hole 12.
