  • Publication number: 20240128486
    Abstract: A fuel cell module has a fuel cell stack and an oxidant gas supply plate. The fuel cell stack is arranged inside a housing. The oxidant gas supply plate is arranged adjacent to the fuel cell stack within the housing. The oxidant gas supply plate has an inner space. The oxidant gas supply plate is positioned separated away from an inner wall of the housing on the first direction side so that a space on the fuel cell stack side communicates with a space on the side opposite to the fuel cell stack side. The oxidant gas supply plate has a surface facing the fuel cell stack and a surface on the opposite side of the fuel cell stack, both being connected directly or indirectly to the housing.

  • Patent number: 11904432
    Abstract: A rotation controlling section of a control unit calculates a maximum thicknesswise difference in a wafer by using a noncontact thickness measuring instrument, and if the maximum thicknesswise difference exceeds a tolerance, relatively changes a rotational speed of a chuck table relative to a rotational speed of a spindle. This can shift a rotational speed ratio, which is a ratio between the rotational speed of the spindle and the rotational speed of the chuck table, from an integer. Therefore, the maximum thicknesswise difference can be made small through spark-out processing. As a result, cyclic variations in thickness value of the wafer are reduced, enabling planarization of a ground surface of the wafer.

  • Patent number: 11277552
    Abstract: An image sensor includes a first and a second polarizing pixels in each of which transmission axis direction is different. Each of the first and second polarizing pixels has a same wavelength characteristic in transmittance, and has a sensitivity to a first and a second wavelength bandwidths. In each of the first and second polarizing pixels, a ratio of the transmittance in the transmission axis direction in the first and second wavelength bandwidths to a maximum value of the transmittance in the transmission axis direction in all wavelength bandwidths is 0.5 or more. In one of the first and second wavelength bandwidths, a ratio of the transmittance in a direction orthogonal to the transmission axis direction to the transmittance in the transmission axis direction is 0.5 or less, and in the other, the ratio is 0.5 or more.
