摘要： A moving apparatus for moving a moving member within a hollow curved pipe arrangement and method of performing operations within the pipe arrangement by using the apparatus, with the apparatus including a long moving member made of a material having an elasticity and a moderate degree of flexibility, a supporting device for continuously winding the moving member therearound and for supporting the same, and a prime mover connected to the supporting device, through a rotating shaft, so as to supply an electric power to the supporting device at the time of winding the moving member, whereby an elastic strain energy is stored in the moving member by rotating the supporting device by the prime mover and winding the moving member around the same, and, while the elastic strain energy thus stored is continuously released, the moving member is allowed continuously to move within the pipe arrangement. The operations performed include drawing a wire into the pipe arrangement, and inspecting the interior of the pipe arrangement by providing an inspection device on a tip end of the moving member of the moving apparatus and performing continuous inspecting operations within the pipe arrangement while the moving member is moved within the pipe arrangement.

摘要： A gas governor apparatus comprises an inner casing removably mounted on an outer casing. Further, a driving mechanism for driving a valve body to control pressure and flow rate of fluid between the valve body and a valve seat formed in the inner casing comprises a drive motor and a drive shaft. The drive shaft has a dual drive sleeve construction where an outer drive sleeve and the valve body are constituted as a rotating drive mechanism and an inner drive sleeve and the outer drive sleeve are constituted as an axial shifting drive mechanism. The outer and inner drive sleeves are axially shiftable by means of an elastic member. The valve body and the inner casing are maintained sealingly by dual expansible members. A flow passage is defined by the dual expansible members and the inner casing. An intermediate pressure chamber is switched to communicate with one of a primary pressure circuit communicating to primary pressure and a secondary pressure circuit communicating to secondary pressure by means of a three-way switching valve to permit introduction of the fluid into the intermediate pressure chamber.

摘要： A chain-like self-moving robot includes three or more capsule units connected to one another in a string by means of couplers. By expanding and contracting intercapsule spaces in a predetermined sequence so that a smaller number of the capsules are moved while a larger number of capsules remain stationary, the chain-like robot can move forwardly or backwardly.

摘要： Method and apparatus for detecting an object by using a radio wave which is radiated by an antenna toward the object to be detected. An echo wave of the radio wave reflected from the object is received by the antenna. On the basis of phase difference between the transmitted waveform and the received waveform, material of the object is discriminatively identified. The object is displayed as an image on a display unit.
