  • Publication number: 20240075383
    Abstract: At a position including coordinates of an input start possible point on a first display, an image indicating the input start possible point is displayed, and at a position including coordinates of an input target point on a second display, an image indicating the input target point is displayed. Then, if a coordinate input to the first display includes an input to a position including the coordinates of the input start possible point, and a coordinate input to the second display includes an input to a position including the coordinates of the input target point, based on trajectories of coordinates of the coordinate inputs to the first display and the second display, a positional relationship between the first display and the second display is determined.

  • Patent number: 9358939
    Abstract: A relay busbar device of one embodiment is a relay busbar device with a built-in current sensor, which is interposed between a motor casing and an inverter casing, and includes a relay busbar both ends of which enter into both of the casings; a resin plate, through which the relay busbar penetrates, and which is interposed between the two casings; a magnetic core, positioned within the resin plate and surrounding the relay busbar; and a magnetic sensor provided in a removed portion of the magnetic core. The relay busbar is mold-formed integrally with the resin plate during resin molding thereof, and changes in magnetic field occurring in the removed portion due to the current flowing in the relay busbar are detected by the magnetic sensor, and the value of the current flowing in the relay busbar is measured.

  • Patent number: 8616744
    Abstract: A vehicle headlamp includes a lamp unit having a bulb attaching portion into which a bulb is inserted and attached, an outer housing configured to engage with the lamp unit at a location behind the bulb attaching portion, an inner housing disposed inside the outer housing such that a clearance is provided in a radial direction between the outer housing and the inner housing and such that, relative to the outer housing, the inner housing is movable in an axial direction and is rotatable about an axis extending in the axial direction, and a spring disposed between the outer housing and the inner housing to bias the inner housing toward the bulb in the axial direction. When the outer housing is engaged with the lamp unit, the spring biases the inner housing such that a flange of the bulb is pressed against the bulb attaching portion.

  • Patent number: 7476995
    Abstract: A busbar (10) has a plurality of straight portions (14) circumferentially arranged at intervals. Several such busbars (10) are tied at a plurality of circumferential spaced positions by connecting the straight positions (14) in parallel with one another. The, the busbars (10) can be positioned with high precision and will not be circumferentially displaced from each other. This can avoid the deviation of intervals between the tabs (16) and those between terminals (18) from correct ones.

  • Patent number: 7219417
    Abstract: To produce bus bars, a conductive metal plate is stamped out into a plurality of strips simultaneously by press molding. Each strip has a tab having an L-shaped cross-section defined by a curved section and a distal end. The plurality of strips are bent in a thickness direction to obtain a plurality of rings, respectively. The rings are mutually different in diameter and have substantially the same center. The L-shaped tab of each of the rings is disposed such that the distal end of each tab is disposed substantially at a same distance from the center.

  • Patent number: 6993829
    Abstract: In a method of producing a centralized distribution unit of a thin brushless motor for a vehicle having superior waterproof-ness and airtight-ness functions, and high dielectric strength, an insulating holder is provided with bearing recesses. Bus bars are bent from a substantially linear shape into a substantially annular shape, and inserted into holding grooves formed in the insulating holder. The insulating holder and bus bars are disposed in a molding cavity, and distal ends of holder supports that project from an inner wall of the molding cavity are engaged with the bearing recesses of the insulating holder. Resin is supplied into the molding cavity to form an insulation layer that covers the bus bars and an entire periphery of the insulating holder.

  • Patent number: 6930418
    Abstract: A centralized power distribution unit for a vehicular thin brushless motor includes a plurality of bus bars, an insulating holder that holds the bus bars to form a predetermined gap between the bus bars, and a resin insulating layer that covers the bus bars. Each of the bus bars has a terminal portion to be connected to a power source, such as a battery, and a tab to be connected to a winding of a stator. The bus bars are disposed correspondingly with phases of the motor. A plurality of holding grooves are formed in the insulating holder. The bus bars, which are pre-bent in a thickness direction to be shaped into a substantially annular shape, are respectively accommodated in the holding grooves. The pre-bending is preferably carried out by a bending machine.

Each of the bus bars has a terminal portion to be connected to a battery and one or more tabs to be connected respectively to one or more windings of a stator. Each of the bus bars is shaped into a substantially annular shape by bending a molded material in a thickness direction. The molded material is obtained by stamping out a conductive metal plate into a strip-like shape. Diameters of the annular shapes of the bus bars are set to be different from one another depending on the corresponding phase of the motor. The bus bars are stacked in a radial direction of the centralized power distribution unit, mutually separated by a predetermined gap.
