A hot water storage tank (3) and a circulating path (12) coupled to the hot water storage tank (3) are provided. An operation is possible wherein low-temperature water, let out from a lower part of the hot water storage tank (3) and entering the circulating path (12), is heated and boiled up by a heat pump heating source for forwarding to an upper part of the hot water storage tank (3). A refrigerant circulating circuit of the heat pump heating source is provided with a defrost circuit (38) for supplying hot gas from a compressor (25) to an air heat exchanger (28). It is possible to perform a defrost operation for providing a supply of hot gas to the air heat exchanger (28), with a water circulation pump (13) of the circulating path (12) held in abeyance. The water circulation pump (13) is made active if the defrost operation has been continued for not less than a predetermined time period since the start thereof.

A hearing aid device for processing an input sound signal via a microphone so as to output a sound signal from an earphone comprises a signal processing element, a couple of acoustic nerve excitation pattern calculation elements, a couple of acoustic filter shape memory elements, a comparison element, a correction processing element, etc. The couple of acoustic nerve excitation pattern calculation elements calculate acoustic nerve excitation patterns of a normal hearing person and a hearing impaired person based on an output signal of the signal processing element and acoustic filter shapes of the normal hearing person and the hearing impaired person which are stored in the couple of acoustic filter shape memory elements. Each of the acoustic nerve excitation patterns is compared via the comparison element. Then, the correction processing element corrects the input sound signal such that the acoustic nerve excitation pattern of the hearing impaired person is identical with the acoustic nerve excitation pattern of the normal hearing person, so as to generate an output sound signal.

In order that an object can be warmed through the use of thermoacoustic effect, the acoustic heating apparatus includes a first stack 3a sandwiched between a high-temperature-side heat exchanger 4 and a low-temperature input-side heat exchanger 5 in a first tube portion 2a and a second stack 3b sandwiched between a low-temperature-side heat exchanger 6 and a high-temperature output-side heat exchanger 7 in a second tube portion 2b. A standing wave and a traveling wave are generated through self excitation in the first tube portion 2a by cooling the low-temperature input-side heat exchanger 5 to minus 20° C. to 60° C. A temperature gradient is generated in the second stack 3b by propagating the resulting standing wave and the traveling wave to the second tube portion 2b, and high-temperature heat is output due to this temperature gradient from the high-temperature output-side heat exchanger 7 disposed on the second stack 3b side.
摘要:
An electric power supply system for a vehicle has an electric power line wired in a loop configuration. From the electric power line power is supplied to a load, and to another system which supplies control system power supply. One shutdown circuit is provided in a module connected to the loop configured power supply line. When the electric power line and the load are short circuited, the shutdown can isolate and shut down only the failure point. Further, when the car is not in use, by stopping the power supply to the load, current consumption can be restrained. In response to detection of a ground short and a failure of a connection of a connector, an over-current prevention of an electric power line, a simple construction can be provided and a low current consumption can be realized.

摘要:
The present invention provides a glove used for household chores such as cooking and washing or other types of work, in which short fibers are flocked on a substrate surface at a vertical or approximately same angle so that the glove is comfortable, highly flexible, easy to put on and remove, and has a pleasant texture. Extra fine short fibers of less than 0.10 dtex are adhered to the inner surface of a rubber or synthetic resin glove substrate. The length of the short fibers is in the range of 0.05 mm and 0.4 mm, and the average thickness of an adhesive layer is in the range of 0.005 mm and 0.05 mm.
