  • Publication number: 20050273228
    Abstract: An inspection item displayed on a liquid crystal display is inspected through a mobile inspection terminal in the state that the inspection screen is displayed. A time necessary to the inspection is measured as an actual inspection time. On the completion of inspection on one inspection screen, the measured actual inspection time is compared with the upper limit value and the lower limit value of a standard inspection time received from a server, and when the actual inspection time deviates from the upper limit value and the lower limit value, a warning is issued by displaying an inspection time warning dialog on the liquid crystal display.

  • Patent number: 6959675
    Abstract: A valve system for an internal combustion engine in which accumulating means can be provided without deteriorating the ease of assembly is provided. A variable valve control mechanism provides control to selectively open and close intake valves and exhaust valves. Pressurized oil supplied to the variable valve control mechanism is accumulated in an accumulator. The body of the accumulator is inserted into and fixed in a hole of a cylinder head. The length of a gap formed between the upper part of the body of the accumulator and a flat plate is set to be shorter than the length of a screw part of the body of the accumulator. Therefore, the accumulator can be replaced and maintained easily, and can be prevented from falling off.

  • Publication number: 20050216152
    Abstract: When the mobile inspection terminal determines that the inspection standard information received from a server is the “specification”, it displays the received inspection standard information and out-of-standard specification information on a liquid crystal display. When it is confirmed in this state that selected inspection standard information is input, whether or not an part to be inspected is acceptable is determined based on the inspection standard information, and the server is notified of a result of determination. Further, when it is determined that the inspection standard information is the “measured value”, a measured value input screen is displayed on the liquid crystal display. When it is confirmed in this state that a measured value is input, whether or not the part to be inspected is acceptable or not is determined based on the input information, and the server is notified of a result of determination.

  • Patent number: 6941908
    Abstract: An engine includes, a cylinder head, an intake valve, an exhaust valve, and a first clearance adjusting mechanism for actuating the intake valve. The first clearance adjusting mechanism (1) maintains a first valve clearance when the intake valve and the cylinder head are in a cold state, such that the intake valve closes after a bottom dead center, and (2) maintains a second valve clearance, shorter than the first valve clearance, when a temperature of the intake valve is in a hot state and a temperature of the cylinder head is still in the cold state, after a cold start of the engine, such that an open timing of the intake valve is advanced and a close timing of the intake valve is retarded. The exhaust valve opens and closes at fixed predetermined timings regardless of a temperature of the exhaust valve and the cylinder head.

  • Publication number: 20050092270
    Abstract: A valve gear for an internal combustion engine capable of promptly switching the position of a piston in a rocker arm to thereby change the engine operating condition with a satisfactory response, even in a low rotation region in which an adequate amount of oil discharged from an oil pump cannot be expected. Depending on positions of pistons slidably fitted in low-speed and high-speed cylinder portions provided in an intake driven rocker arm, a low-speed or high-speed drive rocker arm is selectively operated to press a corresponding one of the pistons. The piston in the low-speed cylinder portion switched in a low rotation region is made smaller in diameter than the piston in the high-speed cylinder portion, to be enabled to be promptly switched.
