  • Publication number: 20160139646
    Abstract: An information processing apparatus includes a request unit configured to request information processing to an image processing apparatus via a network; a return unit configured to cause a request processing apparatus to return to a first operation mode from a second operation mode, wherein the request processing apparatus supplements a function when the image processing apparatus executes the information processing, and the request processing apparatus operates in the first operation mode and in the second operation mode in which power consumption is lower than that of the first operation mode; and a determining unit configured to determine whether the requested information processing is a predetermined type. When it is determined that the information processing is the predetermined type, the request processing apparatus is caused to return to the first operation mode from the second operation mode, before the information processing is requested to the request processing apparatus.

  • Patent number: 9140500
    Abstract: When performing heat storage in a heat storage container accommodating a plurality of kinds of heat storage materials with different melting points, heat storage in the heat storage materials is performed such that a higher melting point heat storage material is in a latent heat storage state as much as possible. In other words, heat storage in the heat storage materials is performed in such a manner that the heat storage materials are in the latent heat storage state in which heat can be stored most effectively. In addition, when performing heat release from the heat storage container to heat coolant water in a circulation circuit, heat release is performed from the heat storage material in the sensible heat storage state as a priority, out of the heat storage materials. Accordingly, heat release from the heat storage container in the heat storage state is performed in such a manner that the heat storage materials are maintained in latent heat storage state for as a long period of time as possible.

  • Publication number: 20130213632
    Abstract: A thermal control apparatus for a vehicle includes a first circulation circuit provided with an internal heat exchange unit, a cooling heat thermal storage unit, and a warming heat thermal storage unit, a second circulation circuit provided with an external heat exchange unit, and a Peltier element that transfers heat between a thermal medium in the circuit and a thermal medium in the circuit. When a request to cool a vehicle interior can be met by the cooling heat stored in the thermal storage unit, the vehicle interior is cooled using the cooling heat stored therein with the drive of the Peltier element stopped. When a request to heat the vehicle interior can be met by the warming heat stored in the thermal storage unit, the vehicle interior is heated using the warming heat stored therein with the drive of the Peltier element stopped.

  • Patent number: 8475337
    Abstract: When there is an extremely low ambient temperature, an electronic control unit controls operation of a circulation path for coolant water in such a manner that, after starting of an engine, the coolant water is supplied from the engine first to a throttle valve and an EGR valve and then to an oil warmer for a transmission. This solves a failure problem in the throttle valve and the EGR valve caused by frost formation at an early stage. As a result, desired operating performance of the vehicle is quickly ensured and heat management in the vehicle is carried out in a desired manner when there is an extremely low ambient temperature.

  • Patent number: 6028595
    Abstract: A touch-screen display which is able to prevent a displacement of a display position and a touch position. The touch-screen display includes a pointing pen for pointing to a position on the touch panel, and which may represent a position of an operator's eye. Moreover, the touch-screen display includes a correction unit for correcting the pointing position pointed to by the pointing pen. Therefore, the displacement of display position and a touch position caused by an angle of an operator's line of sight can be compensated for.

  • Patent number: 4910632
    Abstract: A lightning arrester having an insulating cylinder which contains resistance elements made of zinc oxide which have a nonlinear voltage-current characteristic are stored. The insulating cylinder is fixed at least one sealing member having passages which connect the inside space of the insulating cylinder with the outside space thereof. These passages are covered with a material adapted to be softened or melted by a heat and are therefore closed in an air-tight manner. The arrester also includes an arc guide for producing arc type spark short-circuit externally of the insulating cylinder due to gas jetted from the passages upon an arc accident in the insulatng cylinder.

  • Patent number: 4866393
    Abstract: A method of diagnosing the deterioration of a zinc oxide type lighting arrester having one or more series-connected non-linear resistance elements including steps of elimination of the effects of capacitive currents from phase currents; obtaining a synthesized waveform using a window type transformer based on the resistance elements alone; and diagnosing the presence of a deteriorated non-linear resistance element by generating a first pulse voltage when the maximum crest value of the synthesized waveforms exceeds a predetermined value, generating a second pulse voltage representative of terminal voltage of the resistance element, and calculating the difference between the first and second pulse voltages.
