  • Publication number: 20110172880
    Abstract: A prediction element predicts a predicted arrival time at a destination based on a travel route found by a search element. In normal control mode, the first learning element learns the time period from the time point at which a vehicle is stopped, until an air-based on the predicted arrival time and the result of the learning, a control element estimates a linger period from the present moment until the passenger leaves the passenger compartment after arrival, and, based on the temperatures inside the passenger compartment and the outside as detected by first and second temperature detection element and temperature transition time information, specifies a divergence period from stopping the air-conditioning device until the temperature inside the passenger compartment leaves a comfortable temperature range. The control element stops the air-conditioning device automatically when it is decided that the linger period has become not lager than the divergence period.

  • Publication number: 20110032359
    Abstract: In a server device, each time a photographed image and information related to time of photography are received from one of multiple mobile terminals, a generation processes for generating standard image information based on that image and information related to the time of photography. When generating this standard image information, the generation element generates the standard image information photographed when the moving body passes through that predetermined road junction to satisfy a predetermined speed variation condition. In a mobile terminal, an acquisition element acquires image information from the server device that designates any desired road junction, and, when the moving body passes through that predetermined road junction, a display control element refers to the manner in which the moving body passed through that road junction, and controls a display element to display an image on the basis of that image information. Storage resources are utilized efficiently, enhancing user convenience.

  • Patent number: 5501471
    Abstract: The present invention relates to a mechanical seal for a shaft, having a rotary seal ring and a stationary seal ring which slide on and come in contact with each other for sealing a fluid. A blade-like sealing end portion formed at one seal ring is resiliently pressed, through a coil spring or a flat leaf spring, to a flat sealing end surface formed at the other seal ring. The blade-like sealing end portion is symmetrical at the inner and outer peripheral surfaces thereof with respect to the edge surface thereof, and the angles formed by the inner and outer peripheral surfaces of the sealing end portion with respect to the edge surface thereof are set to 90.degree. or more, and preferably in the range from 105.degree. to 150.degree.. This facilitates the machining of the sealing end portion and prevents the sealing end portion from being broken, thus assuring a stable sealing performance for a long period of time.
