  • Patent number: 8974549
    Abstract: In a vacuum container (2), a bag-shaped laminate film (12) containing a battery element (11) and having an opening (12a) is pinched at positions corresponding to two principal surfaces (11a) of the battery element (11), the battery element (11) having a positive layer and a negative layer stacked via a separator. Pressure in the vacuum container (2) is reduced. An electrolytic solution (20) is poured from an electrolytic-solution supply line (4) into the bag-shaped laminate film (12) through the opening (12a) with pressure in the vacuum container (2) kept reduced until the entire battery element (11) is immersed in the electrolytic solution (20). The reduced pressure in the vacuum container (2) is increased to make the battery element (11) absorb the electrolytic solution (20) by means of the difference in pressure.

  • Publication number: 20140373563
    Abstract: In an air conditioner for a vehicle, a flow speed of air flowing through a first ventilation part of an evaporator is faster than a flow speed of air flowing through a second ventilation part of the evaporator when an intensive air-conditioning operation for a driver seat is operated, with respect to a case where a normal air-conditioning operation is performed. In this case, a correct target evaporator temperature is calculated to be higher by a predetermined temperature than a target evaporator temperature, and a detected temperature detected by an evaporator sensor is approached to the correct target evaporator temperature. Therefore, it can restrict the second ventilation part from being frosted.

  • Publication number: 20140087644
    Abstract: In a vehicle air conditioner, even in a case where an air outlet mode is set in which an air outlet switching damper opens a defroster opening so as to blow air from the defroster opening toward an inner surface of a window glass of a vehicle, the air outlet switching damper is controlled to close the defroster opening when a target air temperature TAO is lower than an outside air temperature TAM. Thus, the vehicle air conditioner prevents a fogging of an outer surface of the window glass without decreasing a temperature comfort in a vehicle compartment.
