  • Patent number: 11977345
    Abstract: A device includes a rotator having a rotation axis, a belt, a nip forming member surrounded by the belt, a holder holding the nip forming member, a first stay supporting the holder, an urging member urging the first stay toward the rotator, a second stay, and a connector. The nip forming member is configured to, with the rotator, pinch the belt to form a nip. The first stay extends in a width direction parallel to the rotation axis. The second stay is positioned upstream of the first stay in a moving direction of the belt at the nip. The moving direction is perpendicular to the width direction. The connector extends through at least one of the first stay and the second stay to connect the first stay to the second stay.

    Abstract: In a bioelectrode capable of detecting biometric information of a living body in touch with the bioelectrode, the bioelectrode includes a base, a first conductive layer that is laminated on a surface side of the base, that is formed by dispersing scale-shaped conductive particles in an insulating binder, and that has extensibility, and a second conductive layer that is laminated on a surface side of the first conductive layer, that has conductivity, and that is harder than the first conductive layer. The second conductive layer is disposed to be exposed at the surface side of the base where the second conductive layer is touchable with the living body. An amount of conductive particles filled in the second conductive layer is smaller than an amount of the conductive particles filled in the first conductive layer. The second conductive layer has a larger outer contour than the first conductive layer.

  • Patent number: 10942436
    Abstract: The reflection surface of a DMD is divided into a first area and a second area, causing the first area to display images while appropriately controlling the on and off states of the micromirrors within the second area on the basis of a prescribed control logic according to the on and off states of the micromirrors within the first area. Further, the DMD off-state light created in the first and second areas is caused to recurse to the DMD via a prescribed recycle optical system for the DMD off-state light, and only the second area in the reflection surface is intensively irradiated along a prescribed irradiation direction, thereby efficiently converting the DMD off-state light to the effective projection light.
