摘要:
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. Further, the spring surface pressure is increased to assure an excellent sealing performance even though the pressure greatly varies.

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.

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.
摘要:
A control system for an internal combustion engine having a plurality of cylinders and a switching mechanism for switching between an all-cylinder operation in which all of the cylinders is operated and a partial-cylinder operation in which at least one of the plurality of cylinders is halted. Operating parameters of a vehicle driven by the engine is detected. The all-cylinder operation or the partial-cylinder operation is performed according to the detected operating parameters. An oxygen concentration sensor is provided in an exhaust system corresponding to the at least one cylinder which is halted during the partial-cylinder operation. A failure of the oxygen concentration sensor is diagnosed in a predetermined operating condition including a fuel-cut operation of the engine upon deceleration. The partial-cylinder operation is permitted after completion of the failure diagnosis.
