Abstract: PURPOSE: A multi-axial rotating device using inertial friction is to provide a precise rotational motion, by using a finite variation of a position generated when a voltage is applied to a piezo-electric element, and by using inertial force and friction force of a sliding part and a moving part. CONSTITUTION: A multi-axial rotating device using inertial friction comprises a plurality of rotation links(10,20,30), a plurality of piezo-electric elements(50), a sliding part and a supporting part(40). The plurality of rotation links includes a circular frame of predetermined thickness and width, a semicircular guide slot formed on a lower part of the internal diameter of the circular frame, and a semicircular frame formed on the external diameter of the circular frame. In the plurality of piezo-electric elements positioned between the guide slot and the semicircular frame, a front end surface of the piezo-electric element is transformed by a predetermined unit of vector quantity if an electric field is formed, and returns to its initial state if the electric field is not applied. The sliding part formed in the piezo-electric element moves along the transformation of the piezo-electric element and slides by an inertial friction if the element moves faster than a predetermined speed. The supporting part supports the rotation links. The piezo-electric element and the sliding part are formed between the plurality of rotation links and the supporting part.

Abstract: PURPOSE: A wire position sensor is provided to prevent a slip of a wire using a measuring shaft having a hole, which is formed on a circumferential surface and contacts with the wire, and an auxiliary shaft, which contacts with an opposite circumferential surface of the wire contacting to the hole and supports a bearing. CONSTITUTION: A wire position sensor includes an encoder part(30) having a measuring shaft(31) in which a hole(36) is formed in a circumferential direction on the center, an encoder(38) connected to an end portion of the measuring shaft(31), and an auxiliary shaft(32) supporting a rotating bearing(35) contacted to an opposite surface of a wire(20) contacting to the hole of the measuring shaft. The measuring shaft is connected to a bracket with a fixing bearing(37) and a snap ring(33) to restrict the movement of the measuring shaft in an axial direction. The auxiliary shaft is fixed with the snap ring in the outside of the bracket and supports the rotating bearing rotating when the wire moves from the hole of the measuring shaft in a longitudinal direction.
