  • Patent number: 8807117
    Abstract: In a situation where a conventional inductive throttle sensor is used with a motor-driven throttle valve device to detect the rotation angle of a throttle shaft, plural sensor connection conductor sections for connecting a connector terminal to a circuit board terminal section are formed on the cover on one lateral surface side of a circuit board in the long-axis direction. This increases the dimension of the cover in the short-axis direction (the dimension in the direction of air flow in an intake path). Consequently, it is difficult to install the motor-driven throttle valve device and inductive throttle sensor in a narrow engine room. This problem is addressed by using a separate member to achieve electrical conduction between a stator circuit board and a conductor routed inside the cover installed over the stator circuit board in a concentrated manner on one side of the circuit board.

  • Patent number: 6837549
    Abstract: A light alloy wheel for a vehicle comprising a disc portion comprising a hub portion and a design portion and a rim portion, the design portion having as-die-cast spoke portions having a taper angle of less than 5.0°. This wheel can be produced by using a casting apparatus comprising a die assembly comprising at least a stationary lower die and a movable upper die, a movable platen to which the upper die is fixed, a first cylinder and at least three synchronous second cylinders mounted onto a frame of the apparatus for moving the movable platen; driving the first cylinder to slowly reduce the clamping force of the lower die and the upper die; synchronously driving the second cylinders to elevate the movable platen in parallel from a position at which the lower die and the upper die are clamped to a position at which the wheel would not impinge on the lower die even if the movable platen were slanted; and then further elevating the movable platen by the first cylinder.

  • Patent number: 6785958
    Abstract: A jig for loosening electric wires of a wire harness passed through a grommet is disclosed. The jig includes a fixing-side clamping portion for clamping the one end of a wire harness, a guide rail extending in a longitudinal direction of the wire harness, a bearing slidably engaged with the guide rail; a lock portion for locking said bearing to the guide rail, a circular rotating member, supported by said bearing, for rotating the wire harness in a circumferential direction of the wire harness; and a movable-side clamping portion, integrally attached to the rotating member, for clamping the other end of the wire harness. The rotating member may have a spiral cam groove, and the bearing may have an engagement protrusion to be engaged with the cam groove so that when the one clamping portion is inverted, the rotating member can move in its longitudinal direction. The one clamping portion may include a rachet mechanism.
