  • Patent number: 10352258
    Abstract: A control device for an internal combustion engine includes a throttle valve opening degree detector, an air bypass valve controller, and a torque reduction controller. The throttle valve opening degree detector detects an opening degree of a throttle valve which is provided downstream with respect to a compressor of a supercharger. The air bypass valve controller opens an air bypass valve based on a reduction change in the opening degree of the detected throttle valve. The air bypass valve is configured to open and close a bypass path. The torque reduction controller controls the throttle valve to reduce the opening degree of the throttle valve while an automatic transmission connected to the internal combustion engine is in an acceleration shifting in order to execute a torque reduction control. The air bypass valve controller maintains the air bypass valve in a close state during the torque reduction control.

  • Patent number: 10355685
    Abstract: An output transistor (2) has a source connected to a VDD1 and a drain connected to an output terminal (1). A pre-driver (3) receives a signal varying in accordance with a data input signal (DIN), and provides a gate signal (SG1) to a gate of the output transistor (2), the gate signal (SG1) transiting between the VDD1 and a potential (VP) at a power source end (4). When a VDD2 is output from an output node (N1) and an assist signal (SA) makes a first transition corresponding to the transition of the gate signal (SG1) from HIGH to LOW, the drive assist circuit (20) performs an assist operation in which a potential of the output node (N1) is temporarily brought down from VDD2.

  • Patent number: 10224665
    Abstract: A connector includes a housing (10) having cavities (13) and deflectable and deformable locking lances (15) project into the cavities (13), and a front retainer (60) to be mounted into the housing (10) from the front. A terminal fitting (50) is inserted into the cavity (13) of the housing (10), and the locking lance (15) resiliently locks a lance receiving portion (54) so that rearward detachment of the terminal fitting (50) is restricted. The front retainer (60) includes a deflection restricting portion (77) configured to restrict the deflection of the locking lances (15), and a retaining portion (69) configured to lock retainer receiving portions (55) and retain the terminal fittings (50) by laterally approaching the terminal fittings (50) by a tilting displacement about a hinge (68) from an opening state to a closing state.

  • Publication number: 20180309221
    Abstract: A connector includes a housing body (11) having a reference surface (18) extending substantially along a front-rear direction, an arm body (21) extending substantially along the front-rear direction, and legs (22) coupling an intermediate location of the arm body (21) in the front-rear direction and the reference surface (18). The area of the arm body (21) before the location coupled to the legs (22) is a lock (31) and the area behind the location coupled to the legs (22) is a releasing portion (32). The releasing portion (32) is pressed toward the reference surface (18), thereby releasing a locked state of the lock (31) and a mating lock (94). The legs (22) are inclined forward from the side of the reference surface (18) toward the side of the arm body (21).

  • Patent number: 9448074
    Abstract: A curve modeling device includes a curvature calculation unit, a curvature correction unit, and a node information generation unit. The curvature calculation unit calculates a curvature of each sampling point on a route based on location information of each sampling point. The curvature correction unit corrects the curvature at each sampling point and approximates the route by a straight line interval, an arc interval, or a smooth curve interval. The node information generation unit builds a shape model of a curve included in the route by generating node information indicative of a node location on a road corresponding to the route based on the corrected curvature of the sampling point. The curvature correction unit corrects the curvature under a condition that an orientation difference defined by the calculated curvatures maintains a constant value.
