  • Publication number: 20170324086
    Abstract: Provided is a method for producing a negative electrode for an electric storage device, the method comprising the steps of preparing a negative electrode composition comprising a negative electrode active material that reversibly carries a sodium ion, metal sodium, and a liquid dispersion medium for dispersing them; allowing a negative electrode current collector to hold the negative electrode composition; evaporating at least part of the liquid dispersion medium from the negative electrode composition held by the negative electrode current collector, thereby giving a negative electrode precursor comprising the negative electrode active material, the metal sodium, and the negative electrode current collector; and bringing the negative electrode precursor into contact with an electrolyte having sodium ion conductivity, thereby doping the negative electrode active material with sodium eluted from the metal sodium.

  • Publication number: 20170276299
    Abstract: A light emitting device includes a semiconductor laser element, a support member and a wavelength conversion member. The support member defines a through-hole through which laser light emitted from the semiconductor laser element passes. The wavelength conversion member has a lateral surface fixed to an inner wall of the through-hole, a first main surface having a first region to which the laser light is incident, a second main surface opposite to the first main surface, and an inclined surface connected to the second main surface and the lateral surface. The inclined surface is inclined such that a thickness of a peripheral portion of the wavelength conversion member is thinner than a thickness of a center portion of the wavelength conversion member. The inclined surface partially overlaps with the first region of the first main surface in plan view.

  • Patent number: 7594146
    Abstract: A time correcting apparatus includes a data input section which inputs all event trace data generated for each event executed on computing devices and outputs the event trace data in order of occurrence time of the event data. An inter-machine communication-time-table generating section extracts transmission and reception events from the output event trace data and generates a communication time table indicating communication times between computing devices based on the differences in occurrence time between the corresponding transmission and reception events. A time-offset deriving section generates a time offset table indicating a time offset value for each computing device based on the communication time table. A time correcting section corrects the event occurrence times of all event data based on the time offset table. A data integrating section inputs all event data whose occurrence times have been corrected and outputs the event data in order of corrected occurrence time.

    Abstract: The attitude of a satellite is controlled by at least three reaction wheels having mutually different rotation axes and at least two control moment gyroscopes having gimbal axes which extend in an equal direction. The reaction wheels and the control momentum gyros are controlled according to calculated values. When the rotors of the gyroscopes are given rotations in opposite directions to each other, angular momentum vectors are produced in respective directions normal to the directions of rotation of the rotors about their gimbal axes.
