Title: Photoscanning device
Inventor: SUZUKI TAKASHI
IPC: G02B26/10
Filed: 1985-12-13
Abstract: PURPOSE:To obtain a small-sized, low-cost, and high-performance scanning lens by using a single lens which is so constituted rotationally symmetrically so that both surfaces are made aspherical and also has a surface inclination correcting function. CONSTITUTION:Projection light from a light source is converged only in the sagittal direction through both a collimator and a cylindrical lens which are not shown in a figure and forms its image linearly nearby a mirror surface SM. The luminous flux is deflected at an equal angular speed in a tangential plane by the rotation of a polygon mirror 5 and reflected at an angle theta of deflection corresponding to the rotation of the mirror 5. Then, the luminous flux after passing through a scanning lens 1 forms its image on a scanned plane 7 at a point T1 whose coordinate value Y is proportional to the angle theta of deflection. The lens 1 has such distortion characteristics that the luminous flux moves on the plane at the equal speed and is the single lens which has both surfaces S1 and S2 made asymmetrical and one or both surfaces made rotationally asymmetrical so that the curvature of field of the luminous flux on the plane 7 is zero or almost zero, so an excellent image formation spot is obtained without any aberration. Further, the scanning lens is constituted which provides wide-angle deflection and is short in optical axis length, so plastic can be used as a lens medium. Thus, the small-sized, low-cost, and high-performance scanning lens is obtained.

Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To provide multitubes for a building structural material, in which dimensional precision is improved while ensuring structural strength and the increase of manufacturing cost can be inhibited, and manufacture thereof and a building. SOLUTION: A column 7 as the multitubes for the building structural material is made up of a plurality of hollow square-shaped steel pipes 8, 9. The hollow square-shaped steel pipes 8, 9 are superposed while having a clearance so that the internal side face 8a of the hollow square-shaped steel pipe 8 and the external side face 9a of the hollow square-shaped steel pipe 9 are opposed adjacently. Since plating treatment 11, 12 and 13, 14 is conducted beforehand to the hollow square-shaped steel pipes 8, 9 and rustproof performance is imparted to the hollow square-shaped steel pipes 8, 9, dip brazing and plating need not be performed to the whole multitubes after welding as seen in conventional devices, and the increase of manufacturing cost can be inhibited.  Since plating treatment is executed beforehand even to the internal side face 9b of the hollow square- shaped steel pipe 9, rustproof performance can be improved approximately equally.
