  • Publication number: 20240106390
    Abstract: The present invention is provided with a plurality of solar power generation panels installed via trestles, where an upper surface of power generation surface of the panels faces the sunlight incidence direction. The solar power generation panels include double-sided incidence-type solar power generation panels provided with power generation surfaces on both the upper and lower sides. A light passage space is provided below a lower surface of a power generation surface. The present invention includes a reflector laid so as to cover a site ground underneath the solar power generation panels and the periphery thereof. The reflector is provided with a reflecting layer including a sheet material with a highly light-reflective colour where the surface side facing the lower surface of power generation surface reflects directly incident light of sunlight and scattered light of sunlight.

  • Patent number: 11938561
    Abstract: A laser processing apparatus includes a light source configured to emit laser light; a power supply configured to supply a current to the light source; a deflection unit on an optical path of the laser light and including an optical element configured to change an amount of transmission of the laser light to deflect at least a part of the laser light; an optical separation unit on the optical path of the laser light and being configured to shield higher-order light included in the laser light and deflected by the optical element in the deflection unit, and transmit zero-order light that is included in the laser light and passes through the deflection unit; and a signal synchronization unit configured to control the power supply to selectively turn the current on or off in synchronization with a timing at which the higher-order light is deflected by the optical element.

  • Patent number: 11866834
    Abstract: The present invention provides an electrode for electrolysis in which electrolysis performance is hard to deteriorate and excellent catalytic activity is kept stable over a long period of time even when electric power in which there is a large fluctuation in output, such as renewable energy, is used as a power source. The electrode for electrolysis is an electrode 10 for electrolysis provided with an electrically conductive substrate 2 at least the surface of which contains nickel or a nickel-based alloy, an intermediate layer 4 formed on the surface of the electrically conductive substrate 2 and containing a lithium-containing nickel oxide represented by composition formula LixNi2-xO2 (0.02?x?0.5), and a catalyst layer 6 of a nickel cobalt spinel oxide, an iridium oxide, or the like, the catalyst layer 6 formed on the surface of the intermediate layer 4.

  • Patent number: 11692276
    Abstract: The present invention realizes industrially excellent effects such that when electric power having a large output fluctuation, such as renewable energy, is used as a power source, electrolysis performance is unlikely to be deteriorated and excellent catalytic activity is retained stably over a longer period of time, and in addition, the present invention provides a technique that enables forming a catalyst layer of an oxygen generation anode, which gives such excellent effects, with a more versatile materials and by a simple electrolysis method.

  • Patent number: 10227242
    Abstract: A membrane electrode assembly includes a rod-shaped or tubular anode, an anode terminal connected to the anode, a cathode disposed at a position apart from the anode so as to face the anode, and a membrane that separates the anode from the cathode. The cathode includes a line-shaped or strip-shaped cathode-supporting portion and a cathode claw that extends to the left, right, or both left and right from the cathode-supporting portion and that is curved along an outer periphery of the anode. The cathode-supporting portion and the cathode claw form an anode-holding portion of the cathode. The membrane includes a membrane strip, and the membrane strip is disposed on the cathode claw to be in contact with the cathode claw so that the anode is held by the anode-holding portion of the cathode with the membrane strip therebetween.
