  • Patent number: 11381155
    Abstract: An overvoltage protection circuit includes an error amplifier, which outputs a first command voltage for bringing the output voltage of a converter closer to a first set voltage, and an overvoltage detection circuit, which outputs a second command voltage for bringing the output voltage of the converter closer to a second set voltage that is higher than the first set voltage. The overvoltage protection circuit controls the converter based on the first command voltage and the second command voltage. Noise immunity can be guaranteed even when an overvoltage detection level is set lower than the level of disturbance noise.

  • Patent number: 10046693
    Abstract: A vehicle lamp includes a light guiding portion configured to be provided in at least one section of a vehicle body panel of a vehicle, and a light source arranged to input light into the light guiding portion such that the light is guided inside the light guiding portion. The light guiding portion has an inner surface and an outer surface. The inner surface is configured to face toward an inside of the vehicle and to serve as a light blocking surface to block the light. The outer surface is configured to face toward an outside of the vehicle and to serve as a light exiting surface from which the light is allowed to exit the light guiding portion. The vehicle body panel may be a vehicle rear panel having a resin molded portion, and the vehicle lamp may be provided integrally with the resin molded portion.

  • Patent number: 9975575
    Abstract: A travel control section 60b is configured to control the revolution velocities of transversely opposite travel motors 51 and 52 such that when turning amount command signals are inputted from a turning amount operation dial 48, transversely opposite crawler travel devices 12a and 12b are caused to realize a turn according to the turning amount command signals by decelerating the traveling velocities of the transversely opposite crawler travel devices 12a and 12b from a target straight traveling velocity set by a travel operation lever 47 by equal values of velocity which are predetermined according to the turning amount command signals inputted from the turning amount operation dial 48 and further decelerating the traveling velocity of the crawler travel device 12a or 12b which is positioned inwardly relative to the other in the turning direction.

  • Patent number: 9944157
    Abstract: A window molding includes a main body and a lip part. The body includes an upper surface configured to be affixed to an inner surface of a window and the body is configured to be arranged between the inner surface and a bottom surface part of a frame. The lip part is provided on a portion of the body located on the peripheral wall part side of the frame. In an assembled state, at least a portion of the lip part extends to be closer to the bottom surface part as approaching from the body side to the peripheral wall part side, and a distance from the upper surface to the bottom surface part is defined as L. When the molding is in an unloaded state, the lip part has a portion in which the distance from the upper surface is longer than L.

  • Patent number: 9541703
    Abstract: A lamp comprises a light guide, a light source and a subject member; wherein an exit surface of the light guide is arranged at a position exposed to a front side of the subject member or located on a rear side of the subject member while being visible from the front side; wherein a surface of a light-guiding part about the exit surface located on the rear side is covered with paint or an opaque member so that the exit surface seen from the front side appears to have the same color as with surroundings thereof; wherein the subject member is molded by an opaque material or the rear side about the exit surface is covered with the paint or the opaque member; and wherein the light guide and the subject member are molded integrally with each other.
