    摘要: 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.

    摘要: 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.

    摘要: A commutator motor includes a stator and a rotor, and the stator includes a stator yoke and a field magnet. The field magnet is fixed onto the inner peripheral surface of the substantially cylindrical stator yoke. The stator yoke is configured by coaxially stacking a plurality of plate-like annular bodies, and the annular bodies are fixedly connected to each other by caulking at a caulking portion disposed on the annular body. In manufacture, the length of the stator yoke in the axial direction can be arbitrarily changed with the thickness of the annular body in the axial direction as a minimum unit. In case of manufacturing various stator yokes that are different in the axial length, the necessity of replacing a manufacturing machine is eliminated, thereby providing a commutator motor having the stator yoke which is low in the manufacturing costs.
