  • Patent number: 10763559
    Abstract: An object is especially to provide a metal-air battery that ensures a high output and continuance of the output over a long period of time as compared with a conventional one. A metal-air battery in the present invention includes a case, air electrodes disposed on both sides of the case, and a plurality of metal electrodes disposed inwardly separately from the air electrodes. The metal electrodes are opposed to one another via a space (S). The metal-air battery of the present invention can inhibit the reaction product from depositing between the air electrode and the metal electrode. A degree of freedom of a distance between the air electrode and the metal electrode is high. As described above, the high output and the continuance of the output over a long period of time are ensured.

  • Patent number: 9417495
    Abstract: A LCD panel is proposed, which meets analog display mode and memory display mode. The LCD panel includes a capacitive element, first to third switch elements, and a circuit. The first switch element turns ON during a first operation for writing pixel potential from signal line to the capacitive element, and turns OFF during a second operation. The second and third switch elements turn OFF during the first operation. The second switch element turns ON during a readout period in the second operation, to read out the pixel potential from the capacitive element. The third switch element turns ON during a write period in the second operation, to rewrite the pixel potential into the capacitive element. The circuit restores a logic level of the pixel potential read out from the capacitive element, and rewrites inversion of the restored logic level to the capacitive element.
