摘要:
An image transmission system for transmitting image data added with code data is disclosed. The image transmission system of the invention has an image transmission device 11 connected with a portable terminal device 13 and a video floppy disk player 12. An image to be transmitted is selected by controlling the video floppy disk player 12 by a command from the portable terminal device 13, and the image is added with code data of the portable terminal device 13 by the image transmission device 11 and transmitted by the image transmission device 11.

A laser welding method includes emitting two laser beams along a weld line from an upper surface side of a workpiece, the two laser beams being transmitted through different optical fibers and having in-focus spot diameters of 0.3 mm or larger; emitting the laser beams such that a leading laser beam of the two laser beams and a trailing laser beam of the two laser beams are each inclined toward a direction in which welding proceeds at an incident angle with respect to a direction perpendicular to an upper surface of the workpiece, the leading laser beam being ahead of the trailing laser beam on the upper surface of the workpiece in the direction in which welding proceeds, the trailing laser beam being behind the leading laser beam; and setting the incident angle of the leading laser beam to be larger than the incident angle of the trailing laser beam.
摘要:
This disclosure provides a radome to be installed on an emission face side of an antenna, which includes an outer wall having a side cross-section formed in a substantially semi-circular shape to include the antenna therein, and an inner wall arranged between the outer wall and the antenna, and formed in a shape to substantially conform to the outer wall. A gap between the outer wall and the inner wall is wider near both ends on the circumference of the substantially semi-circular shape than at a substantially midpoint on the circumference of the substantially semi-circular shape.

A process for producing a periodic structure comprises the steps of preparing a working object which changes a property thereof by photoreaction caused by an exciting energy, generating a light having a photonic energy of intensity of one fraction of natural number divisions of the exciting energy by each of light sources of light-source groups arranged regularly in two-dimensional arrangement, and concentrating the light emitted from the light source group at each of light-concentrating points arranged at regular intervals in the working object to cause photoreaction at and around the light-concentrating point to form a periodic structure comprised of regions each of which has a changed property in the working object.
