  • Publication number: 20230403783
    Abstract: Various technologies described herein pertain to an autonomous vehicle computing device for an autonomous vehicle. The autonomous vehicle computing device includes a printed circuit board, a heat sink, and a thermal interface material layer between the printed circuit board and the heat sink. The autonomous vehicle computing device further includes a barrier layer between the thermal interface material layer and the printed circuit board. The thermal interface material layer can be formed of a two-part thermal interface material that cures in place. The barrier layer between the thermal interface material layer and the printed circuit board enables separation of the printed circuit board from the thermal interface material layer if reworking or modification of the autonomous vehicle computing device is desired. The barrier layer can enable the printed circuit board to be separated from the thermal interface material layer in a manner that mitigates damage to the printed circuit board.

  • Patent number: 11754198
    Abstract: A leakage blocking device of a valve is disclosed. When a fluid flowing in a flow path 11 leaks through a gap between the outer circumferential surface of a valve stem bottom (21) and a bottom guide hole (31), a plug 53 of a piston 50 is pushed into a sealing oil chamber 45 by a pressure P1 of the leaked fluid acting on a bottom pressure acting surface S1 of the piston and pressurizes a sealing oil L in the sealing oil chamber 45 to a pressure P2 higher than the pressure P1 of the leaked fluid, thereby blocking leakage of fluid of the valve.
