The concept of a continuous rotating mechanism is based on the rotation of a waveplate placed in the light path of telescopes for accurate measurements of the degree of polarization of the observed light. This degree of polarization can be used to diagnose the thermal and magnetic properties of the solar atmosphere. High reliability performance with a large number of operations (higher than 10(exp 7)-10(exp 8) rotations) is required for the continuous rotation mechanism used in space-borne telescopes, such as the Solar UV-Visible-near Infrared Telescope (SUVIT) for the next generation solar observing mission (SOLAR-C). In this regard, we completed the development of prototype continuous rotation mechanisms which have a large optical aperture with a pair of large-size thin section ball bearings and a hollow DC blushless motor. We achieved a number of operations higher than 10(exp 8) times by performing lifetime tests in a vacuum environment while upgrading the design of the bearings for improving their performance. These newly developed rotating mechanisms are employed in various solar missions such as the sounding rocket experiment CLASP and CLASP-2, and balloon-borne experiment SUNRISE-3.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
