  • Patent number: 10540234
    Abstract: In a drive apparatus, a transmission unit mounted to a first region stops transmission of a pulse signal from a physical-quantity transmission terminal. The transmission unit transmits, from the failure information transmission terminal, a first signal indicative of an occurrence of the failure associated with the target switch when it is determined that the failure associated with the target switch has occurred, and transmits, from the physical-quantity transmission terminal, a second signal indicative of a content of the failure associated with the target switch. A controller mounted to a second region electrically isolated from the first region detects, based on the pulse signal from the physical-quantity transmission terminal, the physical quantity upon no input of the first signal to the controller. The controller identifies, based on the second signal transmitted from the physical-quantity transmission terminal, the content of the failure upon the first signal being input to the controller.

    Abstract: Provided is an optical signal processing device that can operate simultaneously for a plurality of wavelength bands. The optical signal processing device includes a WDM coupler array including a plurality of WDM couplers for separating the C band and the L band for the respective ports; input/output port groups provided for the C band and the L band, respectively; a micro lens array; a diffraction grating; a lens; and a spatial light modulator arranged in this order. The spatial light modulator collects light at different positions for the respective wavelengths, thus allowing all wavelengths to be independently subjected to a phase modulation. Light subjected to the desired phase modulation by the spatial light modulator is reflected and is deflected to have an angle corresponding to any desired port of the input/output port group, and then is optically-coupled to an input/output port depending on the deflection angle.

  • Patent number: 10301974
    Abstract: An activation control apparatus permits activating a steam turbine safely at high speed in response to a power generation plant state. A heat source apparatus heats low-temperature fluid to generate high-temperature fluid, and steam generation equipment generates steam by thermal exchange with the high-temperature fluid. A steam turbine is driven by the steam, and an adjustment apparatus adjusts a plant operation amount. A thermal effect amount prediction calculation device calculates a prediction value for a thermal effect amount for use for activation control of the steam turbine, and a changeover device decides, based on a state value of the power generation plant, the sensitivity of the thermal effect amount to a variation of the plant operation amount and outputs a changeover signal in accordance with the sensitivity. Based on the changeover signal, an adjustment device calculates the plant operation amount so as not to exceed a predetermined limit value.
