Abstract: Provided with a tire temperature prediction unit 102 configured to calculate a predicted tire temperature at a specific time point based on a history of operation information of a vehicle (V1, etc.) mounted with tires (10a, etc.); a temperature tolerance calculation unit 104 configured to calculate a temperature tolerance at the specific time point; a determination unit 106 configured to determine whether or not the temperature tolerance is within a preset tolerance range; an information generation unit 202 configured to generate vehicle operation change information which changes operation of the vehicle when the determination unit 106 determines that the temperature tolerance is within the tolerance range; and a communication unit 201 configured to transmit the generated vehicle operation change information to the vehicle or to an external system 300 which manages the operation of the vehicle.

Abstract: Provided is an electrical connection box 10 that includes a box main body 12 having a surface 14 provided with a component mounting portion 22 in which an electrical component 30 is mounted; and a cover member 16 covering the surface 14 of the box main body 12, in which an inner surface 48 of a top wall portion 42 of the cover member 16 is provided with a heat dissipation member holding portion 52 that protrudes toward the electrical component 30, and a plastic heat dissipation member 64 held by the heat dissipation member holding portion 52 is made to come into contact with a surface 66 of the electrical component 30.

Abstract: Provided is an electrical connection box that includes: a box main body having one surface on which a plurality of component mounting portions in which electrical components are to be mounted are provided; a cover member covering the one surface of the box main body; a lock mechanism including a locked portion provided on a peripheral wall portion of the box main body and an elastic lock portion provided in a cantilever shape on the cover member. The top wall portion of the cover member is made of a resin material with a greater thermal conductivity than the elastic lock portion provided on the peripheral wall portion of the cover member, whereas the elastic lock portion provided on the peripheral wall portion of the cover member is made of a resin material with a greater elasticity than the top wall portion of the cover member.

Abstract: A waveguide element is formed of a body of plastics resin, such as, acrylonitrile-butadiene-styrene resin, having a tubular portion open at its opposite ends and flanges directed outwardly at such ends, and a conductive layer, for example, of an electroless plated metal such as tin-cobalt alloy, covering the inner surface of the tubular portion and the surfaces of the flanges which face axially in the directions that the respective ends open. For ease of molding or forming the body of plastics resin, such body may be comprised of a pair of complementary parts divided at a plane extending longitudinally in respect to the tubular portion, with such parts having mating flanges directed outwardly along their longitudinal edges and with the conductive layer also covering the confronting surfaces of the mating flanges.
