  • Patent number: 9822725
    Abstract: A control device of an engine includes an adjustment mechanism and a controller. The adjustment mechanism is configured to adjust an intake air amount. The controller is configured to save a first learning value in a volatile storage medium, the first learning value being obtained by learning an operation amount of the adjustment mechanism when the engine is idle. The controller is configured to control the adjustment mechanism according to the first learning value. The controller is configured to save a second learning value in a non-volatile storage medium, the second learning value being equal to the first learning value. The controller is configured to correct the first learning value using the second learning value after the first learning value is cleared.

  • Publication number: 20140251280
    Abstract: A control apparatus that controls a fuel supply system of an internal combustion engine of a vehicle, the fuel supply system including a low-pressure fuel supply mechanism that injects low-pressure fuel into an intake port of the internal combustion engine, and a high-pressure fuel supply mechanism that injects high-pressure fuel into a cylinder of the internal combustion engine, includes a control portion that controls a supply of fuel to the internal combustion engine from the fuel supply system. Immediately after the vehicle stops, when the internal combustion engine satisfies a predetermined condition, the controller idles the internal combustion engine by supplying the high-pressure fuel to the internal combustion engine by the high-pressure fuel supply mechanism, and after stopping the supply of fuel by the high-pressure fuel supply mechanism, idles the internal combustion engine by supplying the low-pressure fuel to the internal combustion engine by the low-pressure fuel supply mechanism.

  • Patent number: 6450468
    Abstract: A sliding drawer device is formed of a first component, and a second component slid ably held inside the first component. The first component includes left and right side walls to be spaced apart and face each other, left and right guide grooves formed in inner sides of the left and right side walls, and left and right slide grooves formed in the side walls to communicate with the respective left and right guide grooves. The left and right slide grooves extend in the back and forth directions. The second component includes left and right outer side portions placed between the left and right side walls to face the same, and a pair of left and right protrusions projecting outward from the respective outer side portions. The left and right protrusions can be inserted into the respective left and right slide grooves through the guide grooves to be slidable along the slide grooves.

  • Patent number: 5881935
    Abstract: A container holding device of the invention is used for holding small things and a container. The container holding device includes a base having a bottom section and an upstanding section extending upwardly from the bottom section, a support member formed near an upper surface section of the upstanding section, and an arm member rotationally attached to the support member to take first and second positions. The bottom section and the upstanding section define at least a part of a holding space in the base. At the first position, the arm member is located on the upper surface section. The arm member can be located above the bottom section, i.e. second position, by changing the position to thereby form a container holding hole together with the upstanding section.
