Title: Regenerative hot-water supplying apparatus
Inventor: MASUDA TAKU
IPC: F24H1/18
Filed: 1992-03-19
Abstract: PURPOSE:To obtain the title apparatus whereby hot water can be supplied, using midnight electric-power or the like and without allowing the hot water to stay in a tank. CONSTITUTION:A fluid 11 in a tank 10 is heated by a heater 12, using midnight electric-power or the like, and its heat is accumulated therein. This fluid 11 is allowed to circulate and is sent to a heat-exchanger 13, and at this point, heat energy in the fluid 11 is transmitted to water. In order that a large amount of the heat energy is transmitted to the water, the operation power of a pump 6 is allowed to increase and the circulation speed of the fluid 11 is made faster, i.e., the rate of circulation is increased. On the other hand, in order that a small amount of the heat energy is transmitted to the water, the operation power of the pump 16 is allowed to decrease, and the circulation speed of the fluid 11 is made slower, i.e., the rate of the circulation is decreased. In this way, the water is heated at an aimed temperature and its hot water is supplied.

Title: Semiconductor light emitting element
Inventor: UEMOTO TSUTOMU
IPC: H01L33/30
Filed: 1987-03-20
Abstract: PURPOSE:To obtain a blue light emission of high light emission efficiency by reducing the thickness and to increase the concentration of a P-type layer to use the layer side as a light irradiating side in a P-N junction light emitting element using zinc chalcogenide crystal containing S or Se. CONSTITUTION:In a P-N junction light emitting element using zinc chalcogenide containing S or Se, the carrier concentration of a P-type crystal layer 13 is increased by tens or more times than that of an N-type layer 12, the thickness of the layer 13 is set to 1.4mum or less, and the layer 13 side is used as a light irradiating side. That is, since a depletion layer is broadened by the N-type layer, when the P-N junction is forwardly biased, hole injection from a P-type crystal layer to an N-type crystal layer is controlled with respect to electron injection from the N-type layer to the P-type layer. Thus, a high blue light emission efficiency is obtained by a P-N junction using zinc chalcogenide.

The Faraday element 2 provides Faraday rotation in inverse proportion to the square of the wave length and a magnetic field H due to the object current to be measured is applied to the element. The polarization separation element 3 divides the light which passed the Faraday element 2 into two polarized light components crossing at right angles each other. The photoelectric transducing elements 4, 5 converts the led light into electric signals. The computer 6 extracts the quantity of light for every wave length of the composite wave from the electric signals converted by the transducing elements 4, 5 and computes the Faraday rotation angle due to the application of the magnetic field H based on the extracted values.

Abstract: PURPOSE:To substantially prevent the generation of a recording error in reciprocal recording, by not only substantially shifting the impact point of a recording liquid on an object to be recorded by integer-times of a dot pitch but also differentiating the emitting timings of the recording liquid in forward and backward paths. CONSTITUTION:In a liquid jet recording apparatus for performing reciprocal recroding, the relation of the distance L between an ink jet head 2 and recording paper P, the absolute value V of the moving speed of the head 2 and the absolute value (v) of an ink emitting speed is set so that the shift of the impact points of ink emitted at the same position on recording paper in the forward and backward paths in the reciprocal movement of the head 2 is substantially n- times [wherein (n) is an integer] of a dot pitch. Further, by preliminarily adjusting the emitting timing of the ink in the forward and backward paths by counting the same over n-dots, the recording error in the reciprocal movement of the head is eliminated or markedly reduced unless the above-mentioned distance L is especially made small.
