摘要： An optical beam scanning apparatus wherein a resin polygonal scanner deflects a light beam radiated from a laser diode as the polygonal scanner is rotating. The polygonal scanner is pressed by a pressing member against a scanner rest which rotates together with a rotary shaft of a motor and thus fixed on the scanner rest. The pressing member has a plurality of tabs, and the polygonal scanner is pressed evenly when the tabs pierce the polygonal scanner.

摘要： A pair of link arms (19A and 20A) each supported at one end thereof on an engine body (1) for swinging movement about an axis parallel to a rotational axis for a valve-operating cam (16) are connected at the other ends, for relative turning movement about an axis parallel to the rotational axis, directly to a rocker arm (18A) having a valve abutment (15) abutting against an engine valve (6) and a cam abutment (17) contacting with the valve-operating cam (16). At least any one of the link arms (19A and 20A) is swingably supported at one end thereof on the engine body (1) for continuous movement within a plane perpendicular to a rotational axis for the valve-operating cam (16). Such an arrangement ensures that a valve-operating system can be constructed compactly, and the opening lift amount of the engine valve can be changed continuously, while ensuring an excellent followability to the valve-operating cam.

摘要： The light beam scanning device has a casing injection molded from magnesium or magnesium alloy as the material. A polygon mirror and a motor are sealed in the inside of the casing and a cover covering the latter. Since the thickness of the magnesium or magnesium alloy material can be reduced, heat generated from a motor is dissipated satisfactorily. Heat dissipating fins are formed to the casing to promote heat dissipation and enhance the strength of the casing.

The lens is so disposed that its beam entrance side and beam exit side are decentered in a direction of the beam scanning, and curvature of the entrance side and curvature of the exit side on a plane of deflection have different centers. The entrance side and the exit side of the lens are a toroidal surface and a spherical surface respectively, and the spherical surface is decentered in a direction perpendicular to the plane of deflection in respect to the toroidal surface. Also, the spherical mirror is decentered in a direction perpendicular to the plane of deflection.

摘要： A drawing method for forming a reflective curved surface by pressing a metal plate fitted in a fixed die with a movable die. The fixed die is composed of a lower die and a core, and the movable die is composed of an upper die and a presser. During the drawing, the metal plate is pressed to have a compressed border portion between a non-pressed portion and a curved surface pressed portion. It is the most desirable to compress the border portion to have a thickness which is 70% of the thickness of the metal plate before drawing.

摘要： One of adjacent rocker arms in a valve operating system of an engine is provided with first and second support walls. A roller is disposed between the first and second support walls to come into rolling contact with cams. A cylindrical roller shaft, supporting the roller, is provided between the first and second support walls, so that a switchover pin of an associative-operation switchover means can be slidably fitted into the roller shaft in response to the movement thereof. The roller shaft is press-fitted into at least a second one of the first and second support walls, and a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the other rocker arm is set smaller than a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the roller.

摘要： A novel laser beam scanning system which stores fundamental components in an optical unit by way of including a laser light source, a photosensor for detecting image-writing starting point per scanning, a lens for focusing a laser beam from the laser light source, and a lens for condensing a laser beam reflected by a polygon mirror on the photosensor. The laser beam reflected by the polygon mirror sequentially scans the photosensor, the laser light source, and a recording medium. When the laser beam reflected by the polygon mirror scans the laser light source, the laser light source ceases light-emitting operation. Furthermore, the laser beam reflected by the polygon mirror is condensed on an edge of a photoreceptive surface of the photosensor.
