Title: Water discharging rate measurement/control device and water discharging form changeover device
Inventor: KOBAYASHI HIROSHI
IPC: E03C1/042
Filed: 1992-02-12
Abstract: PURPOSE:To perform the various types of control based on an accurate water discharging rate obtained from a faucet main body and at the same time to quickly change the water discharging form and to eliminate the unnatural feeling of the switched water discharging form. CONSTITUTION:The detected voltage VP of a pressure sensor 75 set in a hot/ cold water path 62 is compared with the set water discharging rate converted voltage VMN of a flow rate map. The flow rate control is carried out according to the comparison result. That is, the voltage VMN obtained by converting the set discharging rate of each level is compared with the voltage VP. Thus the indirect flow rate comparison is attained and the flow rate can be controlled. Then the water is continuously discharged as long as the voltage VP is kept within an allowable range set on the basis of the voltage VMN. If not, the total inflow of the hot water and the cold water supplied through the pipes 1 and 2, i.e., the flow rate is controlled and corrected by a prescribed amount. Furthermore the water discharging rate is changed in accordance with the voltage VP.

Title: Lighting appliance for motorcycle
Inventor: TABATA HAJIME
IPC: F21S8/10
Filed: 1991-03-01
Abstract: PURPOSE:To provide a lighting appliance for a motorcycle by which excellent visibility can be secured and electric power consumption can be reduced by depositing a reflecting film and a phosphor inside of a glass tube of a fluorescent lamp in order from the outside while leaving a part of the glass tube. CONSTITUTION:A reflecting film 18 and a phosphor 19 are deposited in a cross sectional C shape inside of a glass tube 17 of a fluorescent lamp 13 in order from the inside surface side while leaving a part of the glass tube 17. The fluorescent lamp 13 is installed so that a non-deposited part 17a can turn in the forward direction of a vehicle body. In this constitution, the inside surface of the glass tube 17 has extremely high brightness by such a reason that light emitted from the phosphor 19 causes irregular reflection, to that this light is emitted in the forward direction from the non-deposited part 17a. Thereby, even when a lighting unit is lighted in the daytime, sufficient recognition from a driver in a vehicle running in the opposite direction can be secured. Since the fluorescent lamp is used as an emission source, an irradiation efficiency is excellent as compared with an incandescent lamp, so that electric power consumption can be reduced.

IPC: G01N15/14
Filed: 1987-03-13
Abstract: PURPOSE:To measure the concn. of the suspended particles in a chamber without processing and opening the chamber, by transmitting laser beam and the scattering beam thereof through an optical fiber as it is. CONSTITUTION:When a measuring start order is inputted from an operation part 1, laser beam is emitted from the laser beam source mounted in the operation part 1 to reach the vicinity of the wall surface of a fiber 4 through an optical fiber 17(I) and condensed by two condensing lens groups to pass through the wall surface and transmitted to a measuring part 6 through an optical fiber 20(II). The laser beam operates in the measuring part 6 and collides with suspended particles to generate scattering beam. This scattering beam is condensed to an optical fiber by a scattering beam condensing lens and again reaches the vicinity of the wall surface of the chamber 4 but, herein, said beam is condensed by two condensing lens groups and passes through the wall surface to be transmitted to the operation part 1 through the optical fiber. By this method, the concn. of the suspended particles in the chamber can be measured without processing and opening the chamber.

Filed: 1994-03-30
Abstract: PURPOSE:To perform impedance matching readily by providing a capacitor circuit, which can adjust the capacitance, between a dielectric electrode and an impedance matching circuit. CONSTITUTION:An impedance matching device 2 is constituted of an inverted-L- type LC resonating circuit, and the impedance of a high-frequency power supply circuit 1 and the impedance of a load are matched.

Abstract: PURPOSE:To digitally perform and simply a PWM control by providing an oscillator which generates a frequency corresponding to the integer multiplication of the output frequency and an oscillator which generates a frequency corresponding to a voltage/frequency and counting the ON and OFF of the pulse width modulation with two counters. CONSTITUTION:An oscillator 11 produces a signal for determining the frequency of an inverter A, which is counted by the first counter 12 to allow a memory 16 to produce its content when a switch 15 is closed. An oscillator 13 for controlling the output voltage produces the content of the memory 16 when the switch 15 is opened by applying the signal from the oscillator 13 to the second counter 14. Thus, the bases of the transistors 2-5 of the inverter A are driven through an inverter element 18 and AND gates 19, 20. Accordingly, the modulated frequency is synchronized with the frequency of the inverter, and the V/f can be freely varied, thereby completely digitally performing the PWM control and improving the controllability.

Abstract: PURPOSE:To increase the cycle life of a battery and its safety by constituting a negative electrode with specified mixture powder. CONSTITUTION:A negative electrode is formed in such a way that a mixture of hydrogen storage alloy powder and metal powder having lower melting point and higher hydrogen overvoltage than the hydrogen storage alloy is heated in a vacuum or in an inert gas atmosphere at the temperature which is higher than the melting point of the metal powder and lower than that of the hydrogen storage alloy. The metal of high hydrogen overvoltage diffuses and penetrates onto the surface of the hydrogen storage alloy, and charging efficiency of the hydrogen storage alloy is increased with the property of the bulk retained. The excess evolution of hydrogen gas from the negative electrode in charging is retarded and increase in internal pressure in charge-discharge cycling is prevented. The cycle life of a battery and its safety are increased.
