    摘要: A body frame structure having practically sufficient strength is provided. The body frame structure has a simple structure that can be obtained by simple joining operation. Vertically and horizontally arranged first and second frame members are weld-joined to an outer panel with an end portion of the second frame member facing a side surface of the first frame member. The first frame member is placed in a straddling manner on the outer panel and the end portion of the second frame member weld-joined to the outer panel and is weld-joined to both the second frame member and the outer panel. In this manner, even when the vertically and horizontally arranged first and second frame members are laser-welded to the outer panel, the joint strength can be improved without using a joint plate.

    摘要: An objective lens element that can suppress occurrence of an aberration is disclosed. Sawtooth-like diffraction structures having different height and cycles (pitches) are provided on an inner part R21 and an outer part R22, respectively. A curved surface M211 extending at an intermediate level of recesses and projections of the sawtooth-like diffraction structure provided on the inner part R21, and a curved surface M212 extending at an intermediate level of recesses and projections of the sawtooth-like diffraction structure provided on the outer part R22 are smoothly connected to each other. Even when wavelength of the light source and/or the environmental temperature change, a phase shift does not occur between the inner part R21 and the outer part R22, and a decrease in diffraction efficiency and occurrence of an aberration can be suppressed.

    摘要: An optical synthetic resin composed of: a synthetic resin; and fine particles dispersed in the synthetic resin at a ratio of 0.1 vol % or more to 50 vol % or less, each having a maximum length of 1 nm or more to 30 nm or less, in which part of surfaces of the fine particles are modified with functional groups which themselves repel each other, and a distance between two arbitrary adjacent fine particles among the fine particles is in a range of 0.1 nm or more to 500 nm or less. The two arbitrary adjacent fine particles attract each other with an intermolecular force, thereby making it possible to provide an optical composite deviating from an additivity range.

The optical element includes a symmetry axis, a plurality of optically functional surfaces which are ring-shaped regions around the symmetry axis, and a plurality of wall regions connecting the optically functional surfaces to each other. The optically functional surfaces and the wall regions constitute the optical steps. On a cross-section taken by, as a cutting plane, a plane including the symmetry axis, the contour line of each wall region is substantially parallel to a light beam which is incident on the optically functional surface on the outer side and passes near the wall region. The maximum value of the angle between the symmetry axis and the light beam passing near the wall region is equal to or more than 25 degrees.

    摘要: In a combination of control signals on data signals and the data signals where the combination contains data signals to be assigned respectively to a plurality of streams, a control unit assigns a control signal contained in a leading combination and assigns a data signal, contained in the leading combination, to a position posterior to the assigned control signal. The control unit appends a known signal to at least one of the remaining combinations and then assigns sequentially the remaining combinations to a position posterior to the assigned data signal so as to generate packet signals.
