  • Publication number: 20160269011
    Abstract: A circuit device includes a multiplexer that selects an input signal from first to n-th input signals in a time division manner and outputs the selected input signal to an output node, an A/D conversion circuit that receives the first to n-th input signals outputted from the multiplexer to the output node in a time division manner and A/D-converts the received first to n-th input signals in a time division manner, and a buffer circuit provided between an i-th input node and the output node of the multiplexer. The buffer circuit buffers the i-th input signal and outputs the buffered signal to the output node of the multiplexer in a first period. The multiplexer selects the i-th input signal and outputs the selected signal to the output node in a second period. End timing of the second period comes after end timing of the first period.

  • Patent number: 9421609
    Abstract: In a setting step, a plurality of steel plates configuring a rotor core stacked in an axial direction of a rotor is set in a predetermined position in a mold that is capable of being opened and closed by relative movement in the axial direction. In a casting step, molten metal is fed into a molten metal introduction passage to form a conductive member of the rotor. The molten metal introduction passage has a ring-shaped gate that is opened so as to oppose one axial end surface of the steel plates set in the mold. In a cutoff step, the molten metal is cut off in the molten metal introduction passage so as to be separated into a gate side and a molten metal introduction opening side. In a mold-releasing step, the mold is opened such that a casting configuring the rotor is removed from the mold.

  • Patent number: 8951687
    Abstract: For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.

  • Patent number: 8765315
    Abstract: Deterioration at the start-up and deterioration during the leaving period are suppressed in a good balance. As a system shutdown process, a controller (30) causes consumption of the air (oxygen) present in an oxidant electrode of a fuel cell stack (1) (oxygen consumption control). Further, after the termination of the oxygen consumption control, the controller (30) performs control to set a medium pressure hydrogen valve (13) and a hydrogen pressure adjustment valve (14) in a closed state. The controller (30) thereby causes hydrogen to be held in a passage located between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14). During a system shutdown period, a predetermined amount of hydrogen (medium pressure hydrogen) held in the hydrogen supply passage (L1) at a position between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14) can be supplied to the fuel electrode of the fuel cell stack (1) through a bypass passage (L2).
