Abstract: Provided is an electrical component housing for housing an electrical component. The electrical component housing includes a resin base portion allowing the electrical component to be mounted, a metal cover portion attached to the base portion and configured to cover the electrical component, a metal plate in contact with a bottom surface of the base portion in a manner of covering the bottom surface of the base portion. The electrical component housing also includes a conductive member provided in a through hole that penetrates the base portion in a thickness direction of the base portion, wherein the conductive member electrically connects a ground terminal of the electrical component and the metal plate.

Abstract: A semiconductor device includes a semiconductor substrate with an upper surface and a lower surface, including an n-type semiconductor region having a hydrogen containing region. A carrier concentration distribution representing a carrier concentration by a semi-logarithmic graph in the depth direction of the n-type semiconductor region includes a flat portion containing a first flat part and a second flat part located closer to the lower surface of the semiconductor substrate than the first plat part, and a slope located between the first flat part and the second flat part.

Abstract: In a pneumatic tire, in which a sub-groove 31 extending in a tire circumferential direction is provided on a shoulder land portion inside a width direction center of the shoulder land in a tire width direction, and the shoulder land portion is divided into an inner portion 34 inside the sub-groove 31 in the tire width direction and an outer portion 35 outside the sub-groove 31 in the tire width direction, the shoulder land portion protrudes to the outside of a tire reference profile line L in a normal direction of the tire reference profile line on a cross-section in the tire width direction and a protrusion height H2 at an sub-groove 31 side end of the outer portion 35 is higher than a protrusion height H1 at a sub-groove 31 side end of the inner portion 34.

Abstract: An inner end (27a) of a slit (27) provided in a shoulder rib (25) in a tire width direction is terminated within the shoulder rib (25). The shoulder rib (25) includes a slit region (30) that has the slit (27) and a rib region (31) that has not the slit (27). The shoulder rib (25) protrudes to the outside of a tire reference profile line L on a cross-section in the tire width direction and has a protrusion peak (33) in the rib region (31). A ground contact surface of the shoulder rib (25) draw, on a cross-section in the tire width direction, an arch (M) passing through a ground contact end (22), the protrusion peak (33), and a point (34) on an inner sidewall of a shoulder-side main groove (21) in the tire width direction. The arch (M) passes through a point (35) on the tire reference profile line (L) or outside the tire reference profile line (L) in a normal direction of the tire reference profile line (L) at an inner end of the shoulder rib (25) in the tire width direction.

Abstract: An internetworking system and method enabling efficient communication between networks that use different protocols. A network management station comprises a first connection setting unit, a downstream frame generator, and a frame communication unit. The first connection setting unit establishes a first connection over a network A to reach a gateway network element. The downstream frame generator produces a downstream frame containing identifiers of remote network elements. The frame communication unit sends out the downstream frame through the established first connection, and/or processes an upstream frame received through the same. The gateway network element serves as a mediation device, comprising a second connection setting unit and a frame mediation unit. The second connection setting unit establishes a second connection reaching the network elements, over networks B and C whose protocols are different from that of the network A.

Abstract: A circuit arrangement for different color light emission, comprises first series circuit of a first light-emitting element having a given color, a diode, and a resistor; and a second series circuit of a second light-emitting element having another color and a collector-emitter path of a transistor, where the transistor is responsive to an input control signal so as to change a current flowing therethrough. The first and second series circuits are connected in parallel and are interposed between two terminals of a power source. The impedance of the first series circuit is selected to be much greater than that of the second series circuit when the transistor is conductive. When the voltage of the input control signal is below a predetermined level, the transistor is kept nonconductive so that only the first light-emitting element is energized.
