  • Patent number: 9170281
    Abstract: A current measurement apparatus includes multiple GMR elements and a calculation unit. The multiple GMR elements each include a pinned magnetic layer having a pinned magnetization direction, and a free magnetic layer having a magnetization direction to be changed by an external magnetic field. The calculation unit obtains the magnitude of a current to be detected, from outputs of the multiple GMR elements. The multiple GMR elements are disposed in ring shape around a conductor through which the current to be detected flows, and are electrically connected so as to form a series variable resistor by using the multiple GMR elements. The magnetization directions of the pinned magnetic layers are pinned in the same direction when viewed from an extension direction of the conductor at each of the positions of the elements.

  • Publication number: 20150237698
    Abstract: An LED lamp is used being connected to an external switch for performing an ON-OFF operation. The LED lamp, when causing a light emitting module to emit light in a first lighting mode, controls a power supply circuit to cause the light emitting module to emit light at a first brightness for a predetermined time period from when a timer circuit is activated, and to cause the light emitting module to emit light at a second brightness lower than the first brightness, after passage of the predetermined time period. The LED lamp, when causing the light emitting module to emit light in a second lighting mode, controls the power supply circuit to cause the light emitting module to continue to emit light at the first brightness irrespective of a state of the timer circuit.

    Abstract: A turbine blade has a profile including a blade suction side line, a blade pressure side line, and a blade trailing edge positioned between the rear ends of the blade suction side and pressure sidelines. The blade trailing edge of the profile is formed by connecting a pressure side arc-like curve having a constant radius of curvature and extending from the rear end of the blade pressure side line toward the camber line of the profile, and a suction side line portion which extends from the rear end of the blade suction side line toward the camber line while passing through a region closer to the camber line than a symmetric curve portion which is line-symmetric to the pressure side arc-like curve with respect to the camber line. The suction side line portion is represented by curves constituting ellipses which constitute ellipses, and a straight line.
