    • A radially mounted disk brake has a caliper body secured to a support member secured to a vehicle body. The caliper body has mounting holes extending in a direction perpendicular to the axis of rotation of a disk rotor. Large-diameter hole portions are formed at the openings of the mounting holes on the side thereof closer to the support member. The large-diameter hole portions are fitted with the side wall surfaces of cylindrical step portions provided on the support member in such a manner that gaps are formed between the bottoms of the large-diameter hole portions and the distal end surfaces of the step portions. The center of the axial length of each mounting hole is positioned radially outward of the disk rotor in the axial direction of the mounting hole with respect to a shortest-distance portion of the caliper body at which the distance between the center of a cylinder bore and the mounting hole is shortest.
    • 径向安装的盘式制动器具有固定到固定到车身上的支撑构件的卡钳体。 卡钳体具有沿垂直于盘转子的旋转轴线的方向延伸的安装孔。 在安装孔的开口处形成有大直径的孔部,其侧面靠近支撑部件。 大直径孔部分以设置在支撑构件上的圆柱形台阶部分的侧壁表面装配,使得在大直径孔部分的底部和台阶部分的远端表面之间形成间隙。 每个安装孔的轴向长度的中心相对于卡钳主体的最短距离部分在安装孔的轴向方向上位于盘形转子的径向外侧,在该最小距离部分处,缸孔的中心和 安装孔最短。

    • A laser surface treatment for reducing reflection loss on the surface of an optical material is provided. A metal film is formed on the surface of the optical material, and then the metal film is removed from the optical material by irradiation of an ultra-intense short-pulse laser beam having a pulse width of 1 femtosecond to 100 picoseconds, so that a fine periodic structure is formed on the surface of the optical material exposed by the removal of the metal film. The obtained fine periodic structure has asperities with a periodic interval of preferably 50 to 1000 nm, which can be controlled by changing the laser energy density.
    • 提供了用于减少光学材料表面上的反射损失的激光表面处理。 在光学材料的表面上形成金属膜,然后通过照射脉冲宽度为1飞秒至100皮秒的超强度短脉冲激光束将光学材料除去金属膜,使得 通过去除金属膜而露出的光学材料的表面上形成微细的周期性结构。 所获得的微细周期结构具有优选为50〜1000nm的周期性间隔的粗糙度,其可以通过改变激光能量密度来控制。

    • When a lens holder 2A is in a neutral position, a ratio of a gap between opposing surfaces of one tilt magnet 10a, 10b and one tilt coil 5 which oppose to each other, to a radial direction thickness of the tile magnet 10a, 10b, is in the range of 1/2 to 1/3. In at least one tilt coil of the tilt coils, a ratio of a light axis direction inside distance of the tilt coil to a light axis direction height of the tilt magnet, is in the range of 1/1.5 to 1/4. With this arrangement, even if the objective lens is shifted in a tracking direction or in a focusing direction, variation in the sensitivity and the linearity of the radial tilt movement is small, and an internally accessible area is increased.
    • 当透镜保持架2A处于中立位置时,一个倾斜磁体10a,10b的相对表面与相对的一个倾斜线圈5之间的间隙的比率与瓦片磁体10的径向厚度之比 a,10b在1/2至1/3的范围内。 在倾斜线圈的至少一个倾斜线圈中,倾斜线圈的距离内的光轴方向与倾斜磁体的光轴方向高度的比率在1 / 1.5〜1/4的范围内。 利用这种布置,即使物镜在跟踪方向或聚焦方向上偏移,径向倾斜运动的灵敏度和线性的变化也小,并且内部可访问区域增加。
