Abstract: A body sheet for a vapor chamber includes a first body surface, a second body surface disposed opposite to the first body surface, and a penetration space extending from the first body surface to the second body surface. The penetration space extends in a first direction in plan view. As seen in a cross section perpendicular to the first direction, the penetration space includes a first opening positioned on the first body surface and a second opening positioned on the second body surface. The second opening extends from a region overlapping with the first opening in plan view to a position overlapping with the first groove in plan view.

Abstract: Fractal operation is applied to motion of amenity products or rotating machines within a practical range and motion close to a natural phenomenon is realized by doing it. For example, a washing machine is structured so as to realize washing close to that of washing by hand. Control parameters are given to the control unit regularly and recursively by a fundamental rule and the processing is iterated. Furthermore, at least one of the control parameters is reduced, in which the reduction is effected gradually in accordance with a reduction rate and in which at least one of the reduction rate, the dimension of recursive iteration, and the number of times of self-similar iteration is given as a pseudo random number which varies within a predetermined range.

Abstract: A defrosting apparatus for removing frost deposited on a cooler of a refrigerator or an air conditioner employs a defrosting heater exhibiting a positive temperature coefficient of resistance which changes sharply at a specific temperature. A specific rate of change of the heater current of the defrosting heater is detected, and on the basis of the detected current change rate, stopping or starting of current supply to the defrosting heater is controlled. The defrosting heater is an organic type heater or an inorganic ceramic type heater possessing the function of self-temperature control.
