Title: Neutralization treatment apparatus
Inventor: KOBAYASHI IKUO
IPC: C02F1/66
Filed: 1983-10-31
Abstract: PURPOSE:To enhance the neutralization capacity and clogging resistance of the titled apparatus, by forming a gap between the bottom part of a neutralization treatment tank and a fluid guide plate having communication property and storing a basic substance above the fluid guide plate while flooding acidic water from the lower part. CONSTITUTION:Water supplied from a water supply pipe 7 is subjected to heat exchange in the drum part of a primary heat exchanger 9 and, thereafter, receives heat exchange by a latent heat type heat exchanger 10 and further receives heat exchange in the fin part of the primary heat exchanger 9 to be converted to hot water which is, in turn, issued from a hot water supply arranged pipe 8. In this case, acidic dew condensation water, in which carbon dioxide or nitrogen oxide in combustion exhaust gas is dissolved, is generated to the surface of the latent heat type heat exchanger 10 for recovering latent heat contained in combustion exhaust gas. This acidic dew condensation water is collected in a recovery part 11 and neutralized with the basic substance of the neutralization tank 14 provided to an exhaust passage 12 and discharged out of the main body from an outflow port 12'.

Title: Current detection for high voltage circuit
Inventor: SUZUKI KOUICHI
IPC: G01R31/308
Filed: 1981-12-18
Abstract: PURPOSE:To achieve a simple detection of current in a circuit handling a high voltage  without paying attention to insulation while enabling the insertion of a detection means  into any position of a circuit to be detected at a low cost by detecting current depending on an optical switching action of a light wave guide with a resistance heat generating body inserted into an electric circuit to be detected facing the light wave guide. CONSTITUTION:As current flows through a resistance heat generating body 4, Joule heat  is generated and heats a non-continuity section 3c of a light wave guide. Consequently,  the refraction factor of the non-continuity section 3c (glass) increases to reduce reflection in the interface between the light wave guide 3a and the non-continuity section 3c.  On the other hand, the temperature distribution of a glass substrate 2 is high on the  side of the resistance heat generating body (upper side) and low on the side of a heat  sink. The refraction factor distribution of the glass substrate 2 is high on the side of  the resistance heat generating body and low on the side of the heat sink. This deflects  a light flux dispersed in the glass substrate 2 in the directon of a higher refraction  factor (upper side) to be introduced into a light wave guide 3b on the incidence side in  the direction. Thus, the current flowing through the resistance heat generating body 4  can be detected depending on the quantity of light reaching the incidence side.

Filed: 1986-09-02
Abstract: PURPOSE:To decrease power loss in a frequency range of several hundreds of kHz or more, by performing composite addition of specific substances, in a specified amount, as main components and sub-components. CONSTITUTION:Very small loss ferrite for a power source has composite addition of main components MnO, ZnO, Fe2O3, and sub-components TiO2, Ta2O5, SiO2, CaO in weight ratios of 500-6000ppm, 100-2000ppm, 150-270ppm, 500-2000ppm, respectively. Therefore, power loss can be markedly decreased and very small loss property can be realized sufficiently over a frequency range of several hundreds of kHz or more particularly. This very small loss ferrite for a power source causes heat during its operation when it is used in a magnetic core for a highfrequency power source, however, it can be regulated so that its power loss becomes the smallest in the range of temperatures 40 deg.C to 90 deg.C or so. Hence, power loss in its operation can be decreased.
