    • Automatic focus adjusting device comprising a range finding means which generates a signal corresponding to a distance to an object to be photographed; means for setting a photographing lens to a position corresponding to the output signal from the range finding means; a primary judging means which judges whether or not a diaphragm setting is within the range in which fixed focus photographing is possible or not; and a secondary judging means which judges whether an output signal from the range finding means is at a level capable of operating an automatic focusing means, wherein the secondary judging means judges only when the primary judging means judges that a diaphragm setting is not within the range in which fixed focus photography is possible and the automatic focusing means is operated only when the secondary judging means judges the output signal is at a level capable of operating the automatic focusing means.
    • 自动对焦调整装置,其包括:距离寻找装置,其生成对应于要拍摄对象的距离的信号; 用于将拍摄镜头设置到与来自所述测距装置的输出信号相对应的位置的装置; 判断光阑设置是否在可能进行固定焦点拍摄的范围内的主判定装置; 以及二次判断装置,其判断来自测距装置的输出信号是否处于能够操作自动聚焦装置的水平,其中,次要判定装置仅在主判定装置判断为不在该范围内的光阑设定 其中可以进行固定焦点拍摄,并且只有当二次判断装置判断输出信号处于能够操作自动聚焦装置的水平时,自动聚焦装置才被操作。

    • A method of manufacturing a member having a closed-bottom hole portion by inside-removing-working a raw material made of a carbonaceous material, the closed-bottom hole portion having a hollowed-out side portion and a hollowed-out bottom portion formed by hollowing out an inner portion of the raw material, including: a step of forming a cylindrical trench by digging the raw material frontward from a near-side end face of raw material while rotating the raw material, to form the hollowed-out side portion; and a step of forming the hollowed-out bottom portion by supporting a cutting wire inserted into a bottom portion of the cylindrical trench at two points while rotating the raw material, and pressing the cutting wire being supported at the two points in a direction approaching an axis line of the raw material.
    • 一种通过对由碳质材料制成的原料进行内部去除加工而制造具有封闭底部孔部件的方法,所述封闭底部孔部分具有中空侧部分和中空的底部部分,该底部部分由 对原料的内部进行挖空,其特征在于,包括:在旋转所述原料的同时,从原材料的近侧端面向前方挖掘原料而形成圆筒状沟槽的工序,形成中空侧部分; 以及通过在旋转所述原料的同时在两点支撑插入所述圆筒形沟槽的底部的切割线来形成所述中空的底部的步骤,并且将所述切割丝按压在所述两点处接近的方向 轴线的原料。
