    • PROBLEM TO BE SOLVED: To emit light beams different in beam diameter from an optical fiber structure simple in constitution. SOLUTION: A first optical fiber array 110 where the outgoing ends of four optical fibers 10 are arranged in a line, and a second optical fiber array 120 where the outgoing ends of four optical fibers 20 are arranged in a line are superposed one on the other. For example, the first fiber array 110 includes a V-groove substrate 111 having four V-grooves 112 and four optical fibers 10, the ends of which are fixed to the V-groove substrate 111, and the second fiber array 120 includes a V-groove substrate 121 having four V-grooves 122 and four optical fibers 20, the ends of which are fixed to the V-groove substrate 121. The optical fiber 10 is a multi-mode fiber formed of a core 12 and a clad 14, whose core diameter is 60 μm, and whose fiber outline is 80 μm. The optical fiber 20 is a multi-mode fiber formed of a core 22 and a clad 24, whose core diameter is 105 μm, and whose fiber outline is 125 μm. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:将光束直径不同的光束与构造简单的光纤结构发射。 解决方案:将四根光纤10的出射端排列成一行的第一光纤阵列110和四条光纤20的出射端一行排列的第二光纤阵列120叠加一个 在另一。 例如,第一纤维阵列110包括具有四个V形槽112和四个光纤10的V形槽衬底111,四个光纤10的端部固定到V形槽衬底111,第二光纤阵列120包括V - 槽基板121,其具有四个V形槽122和四个光纤20,其两端固定到V形槽基板121.光纤10是由芯12和包层14形成的多模光纤, 芯直径为60μm,纤维轮廓为80μm。 光纤20是由核心22和芯体直径为105μm的包层24形成的多纤维纤维,其纤维轮廓为125μm。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an endoscope for easily releasing the connection of an operation wire for bending. SOLUTION: The rear end of an insertion part side wire 32a, which is put through an insertion part with a bending part arranged therein, is connected to an electrically driven device side wire 32b, which is extended from an electrically driven bending mechanism part side via a direction changing part 60, by a connection part 52 in a base main body 46. Tooth parts to be mutually engaged are respectively formed in first and second tooth shape bases 52a, 52b which are fixed to the rear end of the insertion part side wire 32a and the tip end of the electrically driven device side wire 32b. The first and second tooth shape bases 52a, 52b, which are in an engagement state, are covered by a cylindrical armor body 52c, so as to hold a connection state. When connection is released, the armor body 52c is moved. Thus, the first and second tooth shape bases 52a, 52b, which are exposed, are separated so as to easily release the engagement state.

    • 要解决的问题:提供一种用于容易地释放用于弯曲的操作线的连接的内窥镜。 解决方案:插入部分侧线32a的后端通过布置在其中的弯曲部的插入部分连接到电驱动装置侧线32b,电动弯曲机构 通过方向改变部分60的一部分,通过基体主体46中的连接部分52相互啮合的齿部分别形成在固定到插入件的后端的第一和第二齿形基座52a,52b中 部分侧线32a和电驱动装置侧线32b的前端。 处于接合状态的第一和第二齿形基座52a,52b被圆柱形铠装主体52c覆盖,以保持连接状态。 当连接被释放时,装甲体52c被移动。 因此,露出的第一和第二齿形基座52a,52b被分离以容易地释放接合状态。 版权所有(C)2005,JPO&NCIPI
