摘要： A two-stage detection noncontact positioning apparatus comprises a light position-detecting mechanism 3 which includes a first light position detector 15 having a slit 17 at a central location corresponding to an optical axis K.sub.4, and a light position detector 16 for receiving a measuring beam S.sub.9 having passed through the slit 17. The first light position detector 15 can be switchably operated such that while the second light position detector 16 receives the measuring beam, the first light position detector 15 is made inoperative not to detect light. The apparatus also includes an optical mechanism 2 having focusing lenses 13 and 14 provided in a manner corresponding to the first and second light position detectors 15 and 16, respectively. As the measuring beam, a semiconductor laser beam, a He-Ne laser beam or the like is suitably employed, which enables the two-stage detection noncontact positioning apparatus to perform highly accurate positioning without being adversely affected by scattered lights.

摘要： A first switch for performing both a weight balancing operation for a main parallel linkage and a weight balancing operation for a supplemental parallel linkage is provided separately from a second switch for only performing a weight balancing operation for the supplemental parallel linkage. An operator can press the second switch during surgery to only correct a slightly unbalanced state of the supplemental parallel linkage in a short period of time, resulting in increased operability of the operation microscope. While the first switch is provided on an operating panel at a stand body, the second switch is provided at a lower part of a distal link located above an operating space for the operation microscope. It is thus easy for an operator to press the second switch during surgery.

摘要： A heliostat 5 for use in a sunlight concentration system for utilizing sunlight as energy according to this invention has a plurality of small concave mirror elements 8 and reflects and focuses sunlight reflected off the individual concave mirror elements to a light concentration portion as if upon reflection off a single large concave mirror 9. The angles of the concave mirror elements 8 are changed to define a single concave mirror having a predetermined curvature. When the incident angle of sunlight with respect to the concave mirror is large, the curvature is reduced (like a shallow dish). When the incident angle is small, the curvature is increased (like a deep dish).
