  • Patent number: 10591223
    Abstract: A heat pipe that includes a pipe casing, a porous wick, and sealing members. Both end portions of the pipe casing are sealed by the sealing members, respectively. The sealing members each comprise a first metal foil and an intermetallic compound phase. The inside of the pipe casing is filled with a working fluid. The porous wick generates capillarity for the working fluid by a plurality of pores. The porous wick is provided inside the pipe casing. As a result, the pipe casing and the porous wick form a cavity extending in a longitudinal direction of the pipe casing. The porous wick comprises first metal grains, second metal grains, and an intermetallic compound phase.

  • Publication number: 20180158338
    Abstract: A driving supporter includes: a departure-possibility-value obtainer that obtains a departure-possibility value; a relative positional relationship obtainer that detects another vehicle located diagonally at a rear of an own vehicle and obtain a relative positional relationship between them; a support executer that executes a lane-departure prevention support; and a support controller that controls the support executer to execute the lane-departure prevention support when the departure-possibility value is greater than or equal to a threshold value. The support controller includes a threshold-value determiner that determines the threshold value to a smaller value when the relative positional relationship is a set relationship than when the relative positional relationship is not the set relationship. The set relationship is a relationship in which there is a possibility of collision of the own vehicle with the other vehicle in an event of departure of the own vehicle from a lane.

  • Publication number: 20170173739
    Abstract: A metal composition that includes a metal component and a flux. The metal component is composed of a first metal powder of a Sn-based metal, and a second metal powder of a Cu-based metal that has a higher melting point than the Sn-based metal. The flux includes a rosin, a solvent, a thixotropic agent, an activator, and the like. When the metal composition is heated to a temperature equal to or higher than the melting point of the first metal powder, the first metal powder is melted. The melted Sn and the CuNi alloy powder produce an intermetallic compound phase of a CuNiSn alloy through a TLP reaction.
