摘要： A portable-terminal-using inspection method for a rotating machine component allows an operating state of a rotating machine component such as a bearing to be easily inspected by using a popularized portable information terminal and a dedicated sensor that supplies detection information to the terminal. The state of the rotating machine component is detected by the sensor. Detection data regarding the detected state is supplied from the sensor to the terminal. Data processing is performed on the detection data in the terminal or a server connected to the terminal via a communication line, by using data processing software and specification data for the model number associated with the component, and a result of the data processing is displayed on a screen of the terminal.

摘要： An electric lock includes an input switching clutch for selectively transmitting electric or manual driving force to an output line. The input switching clutch includes an outer ring that rotates together with an electrically driven input gear, and an inner ring which rotates together with an output gear. Wedge-shaped spaces are defined between the outer ring and the inner ring. Two rollers are mounted in each wedge-shaped space and are biased toward narrow portions of the wedge-shaped space by a coil spring also mounted in the wedge-shaped space. The input switching clutch further includes an unlocking piece having crossbars inserted at both circumferential ends of the respective wedge-shaped spaces, and coupled to a manually driven input shaft so that rotation of the manually driven input shaft can be transmitted thereto; and a torque transmission mechanism for transmitting the rotation of the manually driven input shaft to the inner ring.
