  • Patent number: 11966096
    Abstract: A first lens body and a second lens body are fixed to, using an adhesive layer, a surface of a lens fixing plate determined by intersection of a straight line in an optical axis direction and a straight line in a longitudinal direction, such that the lens fixing plate in which a lens fixing plate opening is formed in a lateral direction overlaps, when viewed in the lateral direction, at least a portion of a junction at which the first lens body and the second lens body are bonded to each other. A first adjustment member is brought into contact with the first lens body via at least one hole into which the first adjustment member is inserted A second adjustment member is brought into contact with the second lens body via at least one hole and into which the second adjustment member is inserted.

  • Patent number: 11956933
    Abstract: No consideration is given to heat transferred from a semiconductor module to a capacitor via a bus bar module. The heat generated by a semiconductor module (1) is transferred to a bus bar module (3) via a DC terminal (1A) of the semiconductor module (1). As illustrated in FIG. 4(B), the heat transferred to the bus bar module 3 is then transferred to the pressing member 5 via the annular conductor 8 and the bolt 5A. Since the pressing member 5 is in close contact with the second cooler 2B, the heat transferred to the pressing member 5 is cooled by the second cooler 2B. On the other hand, the heat transferred to the convex portion 6A of the housing 6 is transferred to the first cooler 2A via the housing 6 and cooled. As a result, in the configuration in which a capacitor (4) is connected to the semiconductor module (1) via the bus bar module (3), the heat transferred from the semiconductor module (1) to the capacitor (4) can be suppressed.

  • Patent number: 11956397
    Abstract: An image reading device includes a lens array including lenses arranged in a main scanning direction and forming an erect unmagnified optical system to converge light from a reading target, a holder holding the lens array, a light receiver to receive the light converged by the lenses, and slit units. Each slit unit includes three or more light shielding plates each separating an optical path of one lens from an optical path of another lens between the lens array and the light receiver, and side plates disposed on two sides of the light shielding plates in a direction intersecting the main scanning direction and connecting two adjacent light shielding plates. The slit units are arranged in the main scanning direction, and each two adjacent slit units are arranged with a space therebetween for one optical path of one lens.

  • Publication number: 20220005274
    Abstract: A surface generation device includes: a profile curve setting unit 2 configured to set a profile curve fitted to a part of shape data, a profile curve movement unit 3 configured to move the profile curve so as to satisfy a predetermined condition, and a surface generation unit 4 configured to generate a surface defined by a locus obtained by moving the profile curve satisfying the predetermined conditions. The predetermined conditions include a condition in which a locus of one point (for example, midpoint) on the profile curve becomes a line of curvature of the surface to be generated. Using such a condition, it is possible to efficiently obtain the high quality surface by setting the line of curvature indicating a flow of the surface as a guide line of a sweep method without repeating trial and error many times.

  • Patent number: 8805908
    Abstract: An approximation processing method for approximating a point group using a curve or a surface defined by control points includes a step of forming an approximated curve (surface) using control points that retain features of a shape; a first calculation step of calculating a closest point closest to each of the data points on the approximated curve (surface); a second calculation step of calculating an error vector that joins the closest point, obtained in the first calculation step, to the data point; and a third calculation step of calculating a corrected control point by moving each of the control points based on the error vector obtained by the second calculation step. The step of forming an approximated curve (surface) and the first to third calculation steps are repeated to make the approximated curve (surface) respectively approximate the curve (surface) of an object configured by the data points.
