    摘要: A bendable portion for an endoscope includes a bending mechanism which minimizes the bendable portion diameter and allows a large degree of bending. A first bending mechanism embodiment uses fluid pressure in an axially oriented chamber in a elastic body of the bendable portion. Expansion restraining members are used to restrict the expansion of the bendable portion to only the axial direction, and to protect internal members in the bendable portion. A second bending mechanism embodiment uses a shape memory alloy coil encircling the elastic body of the bendable portion. The shape memory alloy coil is heated to define the shape of the bendable portion.

    摘要: A projection lens system which produces a smaller amount of residual chromatic aberrations and which will exhibit satisfactory performance even if it is used as a long-focus lens. The projection lens system is composed of a front group and a rear group. The front group includes, in order from the object side, a positive first lens element, a positive second lens element and a negative third lens element. The lens system satisfies the following conditions:-0.0015
