Patent JP-S62277093-A (JP)
Title: Power source circuit
Inventor: WATANABE OSAMU
IPC: H02P7/29
Filed: 1986-05-22
Abstract: PURPOSE:To improve the efficiency of a power source by varying the base current of a transistor which turns ON or OFF at the output to be supplied to a load corresponding to the variation in the load. CONSTITUTION: A selector 7 closes a switch SW1 when a load 2 is started, and opens it at steady time. When the switch SW1 is ON, the base current of a transistor TR2 is determined by a resistance value due to the parallel connection of resistors R3, R6, thereby obtaining a large load current corresponding thereto. When the switch SW1 is OFF, the base current of the transistor TR2 becomes a small current specified by a resistor R6 to obtain a load current corresponding thereto. Thus, even if a load is varied, a power source supply can be maintainly efficiently.

Title: Production of alcohol jelly confectionary
Inventor: IMAIZUMI YASUJI
IPC: A23L21/10
Filed: 1984-06-12
Abstract: PURPOSE:To produce the titled confectionary, capable of preventing the hardening of jelly, enhancing the flavor, and withstanding the preservation for a long period, by kneading a jelly cooled to just before hardening as a main material with a separately processed flavor material containing a powdery alcohol, and stirring the resultant mixture under heating. CONSTITUTION:A jellylike main material prepared by kneading water with thick malt syrup, gelatin, agar, sugar, etc. under heating and stirring is cooled to just before hardening, and a flavor material prepared by separately kneading starch with powdery alcohol and perfume, etc. is added thereto. The resultant mixture is then stirred under heating to knead flavor material uniformly with the jellylike main material. The resultant uniform material is cast into a given container, and cut to a given shape to produce an alcohol jelly confectionary. The separate processing of the jellylike main material and flavor material provides a sufficient viscosity for the jellylike main material. The powdery alcohol is wrapped with the starch, better kneaded under heating and stirring and surrounded by the jellylike main material. Thus, the powdery alcohol is gradually volatilized with the lapse of time and useful for preserving the quality. The flavor is much more improved.

Title: Method of controlling air fuel ratio of engine
Inventor: ITOU YOSHIYASU
IPC: F02D41/10
Filed: 1981-07-31
Abstract: PURPOSE:To avoid the thermal damage of a supercharger provided for an engine, by supplying the engine with a mixture whose air fuel ratio is lower than the theoretical one, when the engine is being run under heavy load higher than a prescribed level and the temperature of exhaust gas threatens to reach a critical level. CONSTITUTION:In the operation of an engine, a controller 50 calculates a fuel injection time on the basis of the output signals of an air flow meter 19, a rotation angle sensor 45, an intake air temperature sensor 41, a water temperature sensor 42 and an oxygen sensor 44 and then judges whether or not the ratio of the quantity Q of intake air to the rotational frequency N of the engine is larger than a prescribed value A. When the ratio Q/N is larger than the prescribed value A, namely, the temperature of exhaust gas threatens to reach a critical level, the controller 50 proceeds to a step to judge whether or not a throttle valve 16 is fully open. When the throttle valve 16 is judged to be fully open, the quantity of fuel is increased after the lapse of a prescribed time. When the throttle valve 16 is not judged to be fully open, the quantity of fuel is increased after the lapse of another longer prescribed time. As a result, the engine is supplied with a mixture whose air fuel ratio is smaller than the theoretical one.

Filed: 1979-09-18
Abstract: PURPOSE:To greatly improve the heat gain efficiency, by making an inwardly  curved heat pipe from a plate body surrounding the back of a solar energy reflective plate, and by providing the heat collecting part and in the heat pipe with heat  medium pipes. CONSTITUTION:The inwardly curved solar energy reflective plate 2 and the plate body 3 surrounding the back thereof constitute the inwardly curved heat pipe 1.

Hence, in addition to the heat collection of heat reflected by the reflective plate 2, the reflective plate 2 itself can absorb heat to be gained, so that the heat gain efficiency is increased. If the reflective surface 2A of the reflective plate 2 is covered with dust, or distorted by heat and the reflectance thereof is lowered, the heat that has  not been reflected can be absorbed by the reflective plate 2 and conducted through  the heat pipe to the heat midium, and therefore the efficiency is not lowered.
