  • Publication number: 20010048808
    Abstract: An apparatus for reproducing video and audio includes a video decoder which receives video data coded by a unit of a first time length, an audio decoder which receives audio data coded by a unit of a second time length different from the first time length, and a synchronization control unit which suspends video output of said video decoder and audio output of said audio decoder, and resumes the audio output a certain time period after resuming the video output where the certain time period corresponds to a period from the suspension of the video output to the suspension of the audio output.

  • Patent number: 6283083
    Abstract: An oil chamber at an upper portion of an outboard engine provides lubrication to a valve gear device within a cylinder head of the outboard engine. Oil passages provide engine oil into the oil chamber. Oil dropping passages on the bottom of the oil chamber permits the oil to flow vertically from the oil chamber into the cylinder head. The oil dropping passages are positioned above the valve end sections to provide sufficient lubrication to the valve end sections of the engine. As a result, the valve end sections are made from material of normal hardness, thereby reducing manufacturing costs.

  • Publication number: 20010005398
    Abstract: A decoded picture and parameters of a sequence layer, a GOP layer and a picture layer respectively for displaying the decoded picture are stored as a set in each of picture banks and parameter banks of a frame memory. Parameters of each layer stored as a set with a picture decoded immediately before are read out. Parameters attached to a picture to be decoded are decoded overwritten. Thus, the parameters of each layer stored as a set with the picture to be decoded are generated.

  • Patent number: 6011869
    Abstract: In storing decoded image data of a picture into a memory 23, PTS1 and a valid/invalid flag F1 corresponding to the picture are stored at the top boundary address ADR1 of a storage area within the memory 23, ADR1 is temporarily held in a register circuit 211. whether a read address ADR coincides with any one of addresses ADR1 to ADR3 within the register circuit 211 is detected while sequentially reading data from the memory 23 to display a picture. When coincidence is detected, the data read from the memory 23 are retrieved as PTS and F, and control corresponding to a time difference between STC and retrieved PTS is executed if F indicates validity. When coincidence is not detected, the data read from the memory 23 are used as display decoded image data DAT4.

  • Patent number: 5971822
    Abstract: An outboard motor air intake device having a throttle body is located essentially horizontally in front of the engine, and includes a surge tank located on a side part of the throttle body, and an air intake manifold with multiple air intake pipes which extend on one side of the engine from the surge tank to each of the cylinders. A throttle valve is located in the throttle body and the linkage mechanism that operates this throttle valve is located opposite to the engine's air intake manifold, so that the linkage is easy to assemble and maintain.

  • Patent number: 5934957
    Abstract: An outboard motor having an oil pan positioned on the underside of the engine, and having an exhaust passage, a water supply passage for cooling water, and a wastewater passage extending down from the engine and passing near the oil pan. The exhaust passage, the water supply passage, and the wastewater passage are molded as a single unit with the oil pan, and provide a simple, lightweight structure that does not result in an increase in the number of parts or assembly man hours necessary for construction. The oil pan is protected from exhaust heat by the water passages, and a flush port to clean the cooling system is easily accessible.

  • Patent number: 5908338
    Abstract: This invention is an outboard motor exhaust device compatible with a small, lightweight cylinder block, which simplifies the exhaust manifold assembly and allows greater precision of assembly. The engine of an outboard motor is located above an engine holder, and comprises a horizontally assembled cylinder head, cylinder block, and crank case. An air intake device is located on one side of the cylinder block, and the exhaust manifold comprising the exhaust device is located on the opposite side of the cylinder block from the air intake device. A side surface of the cylinder head and a side surface of the engine holder are coplanar and form a support for the exhaust manifold.
