  • Publication number: 20100139586
    Abstract: It is a technical common knowledge that a chaplet used in casting of a hollow casting is fusion-bonded with the melt and is incorporated into the casting. However, the adhesion between the chaplet and the casting body is not necessarily satisfactory, thereby incurring the strength reduction of a thin-wall hollow casting. A core for a thin-wall hollow casting according to the present invention is provided with a chaplet mounted thereon. The chaplet has arcuate portion 2 with a gap 5 and a plurality of projections 4 from an outer peripheral of the arcuate portion and is in contact with an inner wall 7 of a mold. The entire arcuate portion of the chaplet is included in a groove 6 formed around an outer peripheral portion of the core body. Only the projections 4 of the chaplet protrude from the core body, when the chaplet is inserted in the groove.

  • Patent number: 7680572
    Abstract: An onboard-equipment control apparatus controls activation of an onboard apparatus such as an air conditioner and termination of the operation of the onboard apparatus in order to prevent an onboard battery from running out of residual electric charge in advance. Upon detection of a state in which an onboard radio apparatus is not capable of receiving a termination command from a cellular phone or the cellular phone is not capable of transmitting a termination command to the onboard radio apparatus while the air conditioner is in operation, the onboard-equipment control apparatus forcibly terminates the operation of the air conditioner even before a termination condition is satisfied. Thus, the onboard battery can be prevented in advance from running out of accumulated electric charge required for operating the activated air conditioner thereafter.

    Abstract: A motorcycle includes a carburetor, an electronically controlled opening/closing valve that opens and closes an intake passage, an ECU that controls the opening/closing valve, a main switch, an engine start switch and a rotation speed sensor. The ECU causes the opening/closing valve to perform a determined initial operation if a determined condition is satisfied when the main switch is turned on. If the determined condition is not satisfied when the main switch is turned on, the determined initial operation is performed when the rotation speed of the engine has reached a determined rotation speed range after the engine has been started. To ensure that an initial operation of an opening/closing valve that opens and closes an intake passage is performed with a high degree of reliability.
