A tool main cutting edge extends rearward in a rotating direction as it approaches a rear end at the outer periphery. The main cutting edge is a convexly curved line protruding toward the outside of a rake face viewed from the top and another convexly curved line extending toward the seat face, convexly curving from one end of the main cutting edge to the other, viewed from the side. When mounted, an inclination angle defined by the rake face gradually decreases from one end toward the other, and a projection line of a rotation about a rotation axis of the tool forms a convex arc smoothly coming, at a middle portion of the main cutting edge, into contact with a cylindrical surface about the axis and gradually retreats inward from the cylindrical surface as it approaches both ends of the main cutting edge.

The present invention provides a bicycle seat post height adjustment mechanism. When said bicycle seat post height adjustment mechanism is in a state of locking, said lower valve packing ring may block said lower valve port, and moreover, based on demands, said upper valve packing ring is allowed selectively to block said upper valve port or to be away from said upper valve port so as to stay on top of said upper valve port. Thus, said pin is driven to axially move down so as to enable said seat post to make fine adjustment, stepless adjustment or stepped adjustment in height; moreover, said seat post may self-return to the assigned position (upper position, middle position or lower position) to prevent the height of the seat from altering.

Measuring light emitted from a laser light source and split into four light rays through optical fibers is emitted into a space from emission units, and bent upward at a mirror. The measuring light passes through a window in the center of the sample stage and strikes a lower surface of the biological sample placed on the sample stage. A portion of fluorescence emitted through excitation by the measuring light passes through the window, is bent in an opposite direction from the measuring light by the mirror, and guided to a fluorescence camera. An objective lens, and a spectroscopic unit for separating visible wavelength components are horizontally arranged between the camera and the mirror. Although the projection of the measuring light and the detection of the fluorescence are performed perpendicularly to the biological sample, the optical components and elements are horizontally arranged.
