  • Patent number: 8813715
    Abstract: A vertical engine includes: an oil pump provided adjacent to the lower surface of a cylinder barrel and connected to a lower end portion of a cam gear shaft to be driven by the gear shaft; a first lubricating oil passageway for supplying lubricating oil from the oil pump to a lower bearing of a crankshaft; a second lubricating oil passageway extending through the crankshaft from the lower bearing to an upper bearing of the crankshaft; a third lubricating oil passageway provided adjacent to the upper surface of the barrel and extending from the crankcase to immediately below stem end portions of intake and exhaust valves so that lubricating oil leaked from the second lubricating oil passageway flows therethrough; and a fourth lubricating oil passageway for returning lubricating oil, dripped down from the third lubricating oil passageway to the stem end portions, to the pump.

  • Patent number: 7343259
    Abstract: There is provided a test apparatus having a plurality of test modules for supplying test patterns used in testing devices under test to the devices corresponding to a given timing signal, a reference clock generating section for generating a reference clock, a plurality of timing supply sections, provided corresponding to the plurality of test modules, for generating the timing signal corresponding to the reference clock and supplying the timing signal to the corresponding test module, respectively, and a control section for controlling timing for outputting the timing signal output by the timing supply section so that timing of the respective test patterns output by the plurality of test modules is practically equalized based on a test module delay of each test module until when it outputs the test pattern after receiving the timing signal.

  • Patent number: 7243638
    Abstract: An injection timing for supplying a fuel by one injection per two rotations to a single-cylinder four-cycle engine of a fixed spark advance ignition system is decided on the basis of a simple system. With respect to ignition signals A1, B1, A2, B2, . . . generated every one rotation of the engine, an intake pipe pressure lowering state exists in one ignition signal cycle A1-B2, and the intake pipe pressure lowering state does not exist in the next ignition signal cycle B2-A2. The signal B1 corresponds to a terminal phase of an exhaust stroke and the signal A2 corresponds to a terminal phase of a compression stroke if these two conditions are established, and an injection timing is decided on the basis of the determination in such a manner that the fuel injection burnt by the ignition of A2 is executed at one time during two rotations.
