  • Patent number: 9227727
    Abstract: A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft.

  • Patent number: 9127815
    Abstract: This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.

  • Patent number: 9083225
    Abstract: A rotary electric machine includes a rotor core, a stator, a field yoke, and a field winding. The rotor core is fixed to a rotary shaft, which includes a magnetic body for forming a magnetic path, and magnetic salient poles. The stator has teeth and a stator winding wound around the teeth by concentrated winding. A slot is formed between adjacent ones of the teeth in a circumferential direction. The field yoke magnetically connects the stator and the magnetic body. The field winding is located in proximity to at least one of the winding ends of the stator winding in an axial direction of the rotary shaft. The field winding generates a magnetic pole on the magnetic salient poles when energized.

  • Patent number: 8896252
    Abstract: An electric motor driving device that drives an electric motor including a field winding, a rotor and a stator, wherein the rotor and the stator each form a field pole by passing a field current through the field winding, includes: a power supply device; a converter including a reactor that at least partially serves as the field winding shared with the electric motor, and configured to receive a voltage from the power supply device to carry out voltage conversion between first and second power lines and to pass the field current through the field winding during voltage conversion operation; an inverter configured to convert a direct-current power received from the converter to an alternating-current power for driving the electric motor; and a controller controlling the converter so that a current flows through the field winding in the same direction both during power running and regeneration of the electric motor.

  • Patent number: 8888632
    Abstract: A silent chain using double-sided driving link plates having symmetrical upper and lower teeth has a problem that it is unable to assure a required risky sectional area of the plates because a width between upper and lower crotches is narrow. The invention provides a silent chain using double-sided driving link plates whose required risky sectional area is maintained by using link plate whose back side is undercut and whose upper and lower parts are unsymmetrical even though its front side has a shape of a normal link plate. A distance from a line connecting centers of pin holes to a bottom of an upper-side crotch is equal to or more than ½ of a diameter of the pin hole to assure the risky sectional area. Teeth of the back side are cut away to form a flat surface to assure a contact area with a shoe and others.
