  • Patent number: 9668321
    Abstract: A safety checking apparatus is provided with a determining section and a result data control section. The determining section determines a safety level of an asset to an incident beam according to an irradiation beam based on the irradiation direction of the irradiation beam and a position or area of the asset. The result data control section carries out a notification to the asset according to the safety level determined by the determining section. Thus, the safety level is determined to a person and a thing one in a region out of a path of the beam.

  • Patent number: 9325149
    Abstract: A multi-beam combining apparatus includes a phase shifting section, a superposing section, an observing section and a phase control section. The phase shifting section generates a plurality of phase-shifted laser beams by shifting the phase of each of the plurality of laser beams. The superposing section generates a plurality of superposed laser beam by superposing the reference laser beam and each of the plurality of phase-shifted laser beams. The observing section generates interference pattern data of a spatial interference pattern which appears when observing each of the superposed laser beams. The phase control section carries out a feedback control of the phase shifts in the phase shifting section based on the interference pattern data obtained for every superposed laser beam, and thereby sets the plurality of phase-shifted laser beams to desired states.

  • Publication number: 20140023951
    Abstract: An electrochemical cell including a fuel electrode having an interface with a fuel gas, a dense ion conductor (electrolyte) and an air electrode having an interface with air (oxygen) layered in this order, the fuel electrode and the air electrode are not in contact with each other and are separated by an electrolyte, and including a functional layer having a porous structure and promoting electrochemical reactions is layered on part or all of a fuel electrode surface that is an interface with the fuel gas. The electrochemical cell allows a high-efficiency electrochemical reaction system that utilizes a gaseous hydrogen fuel that significantly lowers resistance derived from internal diffusion of a gaseous hydrogen fuel gas in a fuel electrode, and makes it possible to achieve, at a single-cell level, a generation efficiency of 40% or more even in a medium-to-low-temperature region at or below 700° C.
