Title: Manufacture of coil
Inventor: ITO FUJIO
IPC: H01F41/06
Filed: 1993-12-13
Abstract: PURPOSE:To obtain a coil which can be manufactured in a short processing time at lost cost and which has a good performance for its small outer diameter by winding copper wires in piles on a line which is the same in radial distance from the center of a winding core. CONSTITUTION:A coil is formed by winding insulating film-coated copper wires 1 directly around an insulating film coated yoke 2. The yoke 2 is in the same size from the center of a circular arc only at a part where the copper wires 1 are wound, and the end part 2a of the yoke 2 is so formed as to have a wider counterarea 2c. Due to this structure, the copper wires can be directly wound around an iron core, etc., by winding the copper wires in piles on a line which is the same in radial distance from the center of a circular arc of a winding core such as a coil iron core and a bobbin. By this method, small and high-performance coil units can be constructured without taking much labor and time and a coil can be manufactured with a good productivity.

Title: Carbonated hot water supplying device
Inventor: INOUE KENSAKU
IPC: F24H1/10
Filed: 1992-11-24
Abstract: PURPOSE:To feed a sufficient quantity of hot water by a method wherein the temperature of outgoing hot water is maintained to be not more than an upper limit value, and a fuel feeding quantity to a hot water supply burner is made close to the maximum value, and under this condition, a water supply quantity to a heat-exchanger, or water supply quantity to a gas-liquid contact section, or water supply quantity from a water supply passage is adjusted so that the temperature of hot water to be fed may become a set target hot water temperature. CONSTITUTION:It is judged whether the temperature of outgoing hot water of a heat-exchanger for hot water supply 3, which is detected by an outgoing hot water temperature thermistor S3, is not less than 90 deg.C, the upper limit value, and continues for a specified period of time, or not. If it does not continue for the specified period of time, a value for which the temperature of hot water supply, which is detected by means of a hot water supply temperature thermistor S4, is subtracted from a set target temperature is calculated. If this value is positive, a gas quantity is increased by increasing the value travel of a gas proportional valve 42, and if the value is negative, the gas quantity is decreased by decreasing the valve travel, and thus, the temperature of the hot water supply is adjusted so that the temperature may become the set target temperature. When this control is repeatedly performed, the temperature of the outgoing hot water of the heat-exchanger for hot water supply 3 can be made closer to 90 deg.C, the upper limit value, and the fuel feeding quantity for the hot water supply burner 4 can be made closer to the maximum value.

Inventor: MATSUSHIMA HIROAKI
IPC: F25B1/00
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent a performance of an air conditioner from being decreased in response to an excessive degree of overheating at an inlet port of a compressor or prevent reverse flow of liquid refrigerant to the compressor by a method wherein one operating state of a refrigeration cycle is monitored and when the other operating state of the refrigeration cycle is varied, a degree of opening of a motorized expansion valve is changed by a predetermined amount to perform a proper control over an amount of circulating refrigerant. SOLUTION: In this case that a temperature detected by an air temperature sensor 22 is higher than a set air temperature, refrigeration cycles 3A and 3B are operated under a control of a controller 2. At this time, in the case that a detected temperature of a discharge temperature sensor 13A is less than a set value, a motorized expansion valve 8A is controlled for its degree of opening in such a way that a degree of superheating at an inlet of the compressor calculated in reference to a difference in temperature between an evaporating temperature sensor 14A and a suction temperature sensor 15A may become a set value. With such an arrangement as above, it is possible to prevent an excessive degree of superheating at the inlet port of the compressor or a liquid back to the compressor, resulting in that a high efficient and high reliable operation can be carried out.
