Title: Water flow control system in water feed device for face washing
Inventor: FUJIMURA AKIHIRO
IPC: E03C1/042
Filed: 1992-06-26
Abstract: PURPOSE:To prevent splash of water from scattering and control the range of water flow by providing an atmospheric bubble crushing board having latticelike shape and a water pressure control member on an upward-facing spout for delivering parabolic water flow. CONSTITUTION:If a valve of a faucet is opened, city water flows from elbows 15-12 and a pipe 11 into a faucet 1 and flows upwardly through a slit between a slit formed plate 21 and the right wall of the faucet 1. And then the water rises through between a valve 18 and the right wall of the faucet, so that the upper end of the valve 18 is displaced to the left by water pressure. Next, the water passes through a gap of an upper wall 2 and gaps of teeth of a water flow control plate 8 and falls fowardly from the upper end of the faucet 1, describing a parabola, while atmospheric bubbles produced by the air remaining in the elbows are broken by the plate 8. When the valve is fully opened, the valve 18 is fully opened to reduce the water pressure, restraining the range of a jet of water from increasing. Further by changing the degree of opening of the plate 8 and the urging force of the valve 18, the range of water is controlled. As a result, scattering of water splashes is prevented and insects are prevented from coming in and the range and direction of the water flow can be controlled.

Title: Optical head temperature compensation mechanism
Inventor: TAKETOMO HIROCHIKA
IPC: G11B33/14
Filed: 1986-08-21
Abstract: PURPOSE:To prevent the occurrence of distortion due to the difference of thermal expansion coefficient by attaching a compensating material, which consists of materials having the same thermal expansion coefficient as an actuator, to the other face of an optical case whose one face the actuator is attached to. CONSTITUTION:A compensating material 2 which consists of the same materials as an actuator 13 or materials having the same thermal expansion coefficient as the actuator 13 and has the same thickness as an actuator base is provided in such position that the compensating material 2 faces the actuator base 3 with an optical case 1 between them. Though the actuator base and the optical case are distorted by the variance of ambient temperature because they consist of different kinds of material, the distortion force whose direction is opposite to that of the distortion force generated by the actuator 13 and magnitude is approximately equal to that of this distortion force is generated by the optical case 1 because the compensating material 2 is attached to the position facing the actuator 13 with the optical case 1 between them, and as the result, both distortion forces are cancelled by each other and distortion does not occur in the optical case.

Title: Fluidized bed combustion device
Inventor: TAMAKI MINORU
IPC: F23J15/02
Filed: 1988-08-03
Abstract: PURPOSE:To effectively utilize limestone being fed and to reduce an amount of generated ash by a method wherein, in a fluidized bed combustion device having a fluidized bed boiler having limestone serving as a fluid medium, a water injecting device is situated in an exhaust gas flue, and the length of a flue running between the water injection device and a dust collector is set to a value long enough to allow the reaction of unreacted quick lime to water. CONSTITUTION:A water injection device 8 is located in an inlet flue 12 of a collector, and is formed such that water can be injected in exhaust gas in a flue. A flue 12 between the water injection device 8 and a dust collector 9 has length long enough to ensure a gas stagnation time of at least three seconds so that the reaction between Ca(OH)2 and SO2 can take place. By injecting water in exhaust gas, water is caused to produce steam by means of the sensible heat of gas. The steam reacts to CaO in exhaust gas, Ca(OH)2 reacts to SO2 to produce CaSO3. Since CaSO3 is produced in a solid powdery state, it is collected by a dust collector 9 located on the wake flow side and is discharged. Since SO2 in exhaust gas can be desulfurized outside of a fluidized bed by means of flying ash, a factor of desulfurization effected in a fluidized bed 5 is decreased, an amount of lime stone charged in the fluidized bed can be decreased, unreacted CaO is decreased, and an amount of waste ash generated from the dust collector 9 is decreased.

Title: Flow rate measuring apparatus
Inventor: ADACHI IKURO
IPC: G01F1/115
Filed: 1988-08-03
Abstract: PURPOSE:To enables stable detection of a flow velocity of a fluid with respect to a change therein with a high response by detecting it based on a level of a rate of change in a rotational speed of a rotor rotating by a flow of the fluid. CONSTITUTION:A rotational speed of a rotor 1 rotating by a flow of a fluid is detected with a rotational speed detection means 3. When a rate of change in the rotational speed detected is lower than a specified rate of change, a rotational speed of the rotor 1 and the previous rotational speed are averaged by a rotational speed recognition means 3 to recognize the rotational speed thus averaged as rotational speed of the rotor 1. When the rate of change in the rotational speed is higher than the specified value, the rotational speed detected by the rotational speed detecting means 2 is recognized as rotational speed of the rotor 1 as intact. This enables detection of a rapid change in the flow rate with a high responsiveness thereby minimizing variations in the flow rate to be detected due to a fluctuation of the rotor.
