Title: Vehicular fuel tank
Inventor: TANIGAWA HIROSHI
IPC: G01F23/38
Filed: 1992-08-12
Abstract: PURPOSE:To provide a vehicular fuel tank by which an oil transfer pump can be operated efficiently in transferring fuel to a main tank from a sub tank in the vehicular fuel tank having two tanks of the main tank and the sub tank. CONSTITUTION:A full tank sensor 20 is arranged in a main tank 10, and this detects that the main tank 10 is put in a full condition. Operation of an oil transfer pump 54 is stopped by detecting this full condition, and oil transfer is stopped. Thereby, since there is no need to arrange a pipe to circulate excessive fuel, useless pump operation can be avoided. An empty sensor 42 is arranged in a sub tank 40, and the operation of the oil transfer pump 54 is stopped by detecting this empty condition, and the oil transfer is stopped. Thereby, since the oil transfer pump 54 runs idle, this can be prevented from running into trouble.

Title: Measuring method of frequency characteristic of light modulator and measuring apparatus therefor
Inventor: KAWANISHI SATOKI
IPC: G02F1/00
Filed: 1988-08-31
Abstract: PURPOSE:To conduct accurate measurement over a wide band of 10GHz or above by using for measurement a light beam signal generated from two continuous lights being different in an oscillation light frequency of a semiconductor laser. CONSTITUTION:First, output lights of two semiconductor lasers 11 and 12 are synthesized by an optical synthesizer 14. On the occasion, each laser oscillation light frequency is controlled by a controller 13 so that a beat frequency omegab being a difference between the laser oscillation light frequencies be a value approximating to an oscillation frequency omegas of an oscillator 16 driving a light modulator 15. Said synthesized output light is made to enter the modulator 15. Meanwhile, the modulator 15 modulates the intensity of the light with an electric signal of the frequency omegas by an output of the oscillator 16. The modulated light is received by a light-receiving circuit 17. The amplitude of a component omegas-omegab at the time when the frequency omegas is varied in succession is proportional to Fm (omegas) and represents the modulation characteristic of the modulator 15 at the frequency omegas. Since a squared value of an output photocurrent is measured in a spectrum analyzer 18, measured frequency response is proportional to F<2>m (omega) and an Fm (omega) characteristic is determined by the conversion.

Title: Vaporization system
Inventor: YABE AKIRA
IPC: F25B39/02
Filed: 1989-08-24
Abstract: PURPOSE:To maintain the electric conductivity of a heat medium at the optimum value in a vaporizer irrespective of any load of the vaporizer by recovering a conductive matter with recovery equipment or returning conductive matter thus recovered. CONSTITUTION:On/off valves V3, V4 are closed while on/off valves V1 and V2 are opened. Then, a heat medium is extracted from a vaporizer 1 by starting a pump P. The extracted heat medium is introduced into recovery equipment 2 by way of the on/off valve V1, the pump P, and the on/off valve V2. Then, the heat medium is heated by a heating medium by way of a heat exchanger tube 2a, boiled and vaporized. The vaporlproduced from a dielectric joins the vapor of a dielectric discharged from the vaporizer 1, and circulates the system, but the dielectric is hardly vaporized. Therefore, it remains inside the recovery equipment 2. As a result, the concentration of the dielectric included in the heat medium circulating through the system drops excessively. When the electric conductivity of the heat medium drops at the point Q and below, the on/off valves V1 and V2 are closed while the on/off valves V3 and V4 are opened so that the heat medium with the high concentration of the dielectric in the recovery equipment 2 may joint the heat medium which flows into the vaporizer 1 by way of the on/off valve by driving the pump P. It is, therefore, possible to maintain the concentration of the dielectric of the heat medium in the vaporizer 1 at the optimum value Q.
