  • Patent number: 10926530
    Abstract: A printing object surface has a cross-sectional shape curving along a printing advancing direction. The printing advancing direction is defined as a Y-axis, a direction orthogonal to the Y-axis and belonging to the cross-section is defined as a Z-axis, and a direction around an axis orthogonal to a Y-Z plane is defined as a ?-axis. A squeegee is disposed so as to be movable in the respective Y-, Z- and ?-axis directions. Information indicating a mutual relationship among respective Y-, Z- and ?-axis positions is obtained. The relationship is a relationship that enables performing printing while maintaining or substantially maintaining an angle formed by a direction tangent to a printing position in the printing object surface in the Y-Z plane and the squeegee. Printing is executed while the respective Y-, Z-, ?-axis positions of the squeegee relative to the printing object surface are controlled according to the obtained information.

  • Publication number: 20200410641
    Abstract: With respect to two images acquired from two video images including a mutually-overlapping area in which the two video images overlap each other, an image transformation matrix for mapping coordinate systems is sequentially generated. Coordinate transformation of at least one image of the images is performed using the generated image transformation matrix. A composite image is created by overlaying two images with the at least one image subjected to the coordinate transformation. The currently used image transformation matrix and the newly generated image transformation matrix are compared with each other. If the two image transformation matrices are similar, the coordinate transformation is performed using the currently used image transformation matrix continuously. If the two image transformation matrices are dissimilar, the coordinate transformation is performed using an image transformation matrix corrected with the newly generated image transformation matrix.

  • Publication number: 20200391660
    Abstract: An attachment structure includes a support part for an in-vehicle device, a plate spring attached to the support part, and a screw screwed into the support part. The attachment base slides and is received in a space interposed between left and right plate spring pieces. The screw is fastened in this state. A screw distal end presses a front surface of the attachment base to generate an appropriate force of fitting between the attachment base and the left and right plate spring pieces and thereby the attachment base and the plate spring are elastically fitted with each other. The in-vehicle device is attached to the attachment base via the plate spring using the elastic fitting. If an external force that is equal to or exceeds a predetermined value is applied to the in-vehicle device, the elastic fitting is cancelled and the in-vehicle device drops off from the attachment base.

  • Patent number: 10807534
    Abstract: Crest-valley repeated shapes that are fitted to each other by a biasing force of a spring are disposed so as to be opposed to each other in opposed surfaces that are opposed to each other and rotate relative to each other between a view device base side and a view device rotating section side. Respective height maintaining protrusions are disposed so as to be opposed to each other in the opposed surfaces. Upon the view device rotating section being rotated from an extended position toward a forward-tilted position by an external force, respective top surfaces of the height maintaining protrusions are brought into abutment with and slide on each other in a position in which abutment between respective top surfaces of the crests of the crest-valley repeated shapes is cancelled, to maintain a height of the view device rotating section.

  • Patent number: 10809584
    Abstract: In a mirror display apparatus, a mirror optical element in which reflectance and transmittance vary in opposite directions to each other by electric driving is disposed on a front surface side of a monitor display device. An operation mode of the mirror display apparatus is switchable between a monitor mode and a mirror mode for use. A temperature sensor is installed to a mirror display apparatus. In the monitor mode, the temperature sensor is used for a temperature control of the monitor display device, or a temperature compensation control related to display quality, or the both. In the mirror mode in which the mirror optical element is in a reflectance-reduced reflection mirror state, the temperature sensor is used for a temperature compensation control of reflectance of the mirror optical element.

  • Patent number: 10793072
    Abstract: This invention intends to prevent generation of abnormal sound. A motor shaft is inserted in a center hole of a worm and fitted in the center hole in a direction around an axis of the worm. A distal end of the worm is received in a bearing recess. A worm wheel engages with the worm. A radial gap and rotational play are formed between the motor shaft and the center hole of the worm. A radial gap is formed between the distal end of the worm and the bearing recess. The gap between the distal end of the worm and the bearing recess is formed so as to have a size that prevents an outer circumferential surface of the distal end of the worm and an inner circumferential surface of the bearing recess from coming into contact with each other when the worm is rotating.
