  • Patent number: 9947851
    Abstract: The present invention provides a LED package in which deterioration in heat radiation performance is suppressed. The LED package comprises a substrate, a light-emitting device mounted on the substrate, sealing resin sealing the light-emitting device and mixed with phosphor, a heat sink provided on a rear surface of the substrate, and a rear electrode provided on the rear surface of the substrate and electrically connected to the light-emitting device. The heat sink is provided at a distance from the rear electrode in a region except for the rear electrode. The heat sink is divided into eighteen small heat sinks by grooves formed in a rectangular lattice pattern. When the LED package is mounted on a mounting substrate, the gas generated from solder is efficiently discharged through the grooves to the outside, thereby suppressing the generation of air bubbles between the heat sink and the solder.

  • Patent number: 9939060
    Abstract: In a shift lever device, at a time when a shift lever is pivotally operated in a front-rear direction, a retainer and a link are pivoted integrally with the shift lever, and a pivot portion is pivoted in the front-rear direction. Further, at a time when the shift lever is pivotally operated in a left-right direction, the shift lever is pivoted with respect to the retainer, and the link is pivoted, and the pivot portion is thereby pivoted in the left-right direction. Moreover, a position of the pivot portion is detected by a detecting mechanism, and a shift position of the shift lever is detected. Therefore, the shift position of the shift lever can be detected via the link.
