  • Patent number: 8784972
    Abstract: Disclosed is a composite sheet 1 composed of a substantially flat lower fibrous sheet 3 and an upper fibrous sheet 2 bonded to the lower fibrous sheet 3. The upper fibrous sheet 2 is three-dimensionally textured with a number of projections 5 and a number of depression 6 each of which is located between every adjacent two of the projections 5. The projections 5 and the depressions 6 alternate in both a first direction of the composite sheet 1 and a second direction perpendicular to the first direction. Each projection 5 has a pair of opposing first walls 51 parallel to the first direction and a pair of opposing second walls 52 parallel to the second direction. The basis weight of the first walls 51 is different from that of the second walls 52.

  • Patent number: 8606462
    Abstract: There is provided a electric power steering device which can perform torque control through a simple arithmetic process using a synchronous reluctance motor having a nonlinear current/torque characteristic. A target torque is transmitted from an EPS control unit 41 to a motor control unit 51. The motor control unit 51 calculates a target-current effective value I and a target-current phase ? from the input target torque. Based on the calculated target-current effective value I and target-current phase ?, calculation is changed whether to perform calculation so that the maximum torque (the maximum torque obtainable at the minimum current effective value) can be obtained, or to perform calculation so that the maximum output (the maximum output obtainable at the minimum current effective value) can be obtained in accordance with a duty ratio of an output by a PWM converting unit 57 comprising a three-phase inverter.

  • Publication number: 20100007779
    Abstract: A solid-state imaging device includes a semiconductor substrate having a pixel region including a photoelectric conversion portion, a wiring portion including a conductor line and disposed on the semiconductor substrate with an insulating film therebetween, a metal pad connected to the conductor line, a pad-coating insulating film coating the metal pad, and a waveguide material layer. The wiring portion and the pad-coating insulating film each have an opening therein over the photoelectric conversion portion, and the openings continue from each other to define a waveguide opening having an open side and a closed side. The waveguide material layer is disposed in the waveguide opening and on the pad-coating insulating film with a passivation layer therebetween. The pad-coating insulating film has a thickness of 50 to 250 nm and a face defining the opening. The face is slanted so as to diverge toward the open side of the opening.
