IPC: G02B6/42
Filed: 1989-02-01
Abstract: PURPOSE:To enhance the utilization rate of the light from a light source by reflecting the radial light emitted from a photoconductor in the mirror part of a holed mirror and making this reflected light incident to a light receiving element by an optical system. CONSTITUTION:The incident diffracted light is reflected by the mirror part 53 and is made incident to the mirror 102 of a reflector 100; thereafter, the light progresses along an optical axis 72a and is condensed to the center of the light receiving face of the light receiving element 70. The light receiving element 70, therefore, provides the effect of detecting the light by conduction of a photodiode arising from the photodetection of the element. The beam light from the light emitting element 30 is hardly lost at the time of the passage through the central hole 52 of the holed mirror 50, the reflection by the holed mirror 50 and the reflection by the mirror 102. The holed mirror 50, a planoconvex lens 40 and the mirror 102 are disposed into the optical route between the light emitting element 30, the optical fiber 90 and the light receiving element 70 in this way, by which the utilization rate of the beam light from the light emitting element 30 is improved.

Abstract: PURPOSE:To provide a hot water feeder which improves facility, by a method wherein, when a faucet is closed during combustion, by running a fan for combustion air at a high rotation speed for a specified time and thereafter running it at a low rotation speed for a specified time, when the faucet is opened again, hot water having temperature higher or lower than a using temperature is difficult to flow out. CONSTITUTION:When, during combustion by a burner 7, a water quantity detected by a water detecting device 1 is decreased to a value lower than an extinguishing water quality, the burner 7 is forced to stop combustion by a fan control means 15. A fan 8 for combustion air is run at a high rotation speed for a specified time, and thereafter it is run at a low rotation speed for a specified time. As a result, when a faucet is closed and opened again, since the fan 8 is run at a high rotation speed for a specified time of the initial stage, hot water having temperature higher than a using temperature during the reuse is difficult to flow out. Since, after a lapse of a specified time, the fan 8 is run at a low rotation speed, hot water having temperature lower than a using temperature during the reuse is hard to flow out, the generation of noise is reduced, and a hot water feeder which is gate and improves facility is provided.

Title: Measuring of light intensity by photo-multiplier
Inventor: HAYASHI HIDECHIKA
IPC: G01J1/42
Filed: 1979-03-02
Abstract: PURPOSE:To enable the measurement for a wide range of samples by a method wherein applied voltage is varied for each measurement of multiple cells corresponding to the light intensity so as to allow the photo-current to be flowed within the measuring range of detecting circuit, and voltage and current at that time are measured. CONSTITUTION:Photo-current i is changed to vi though current-voltage convertion by an amplifier 7 and then becomes to log vi by a log amplifier 8, thereafter being fed to an amplifier 9. On the other hand, applied voltage v is divided by resistors R1-Rn+1 and r, and becomes vc by an amplifier 10, log vc by a log amplifier 11 and then betalog vc by an amplifier 12 with a gain beta, thereafter being fed to the amplifier 9. The amplifier 9 outputs the difference between above two inputs as -omega(lambda), so there is obtained an output with reversed sign as omega(lambda)=log vi- betalog  vc=log I+log k(lambda)+g: where k(lambda) is a function depending on only wave length lambda  of transmitted light and beta is a constant. They are specific values of a photo-multiplier 4. By so doing, it becomes possible to measure the light intensity for a wide  range of samples.
