IPC: G03B15/05
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To enable a stroboscope to emit light at exact timing. SOLUTION: A synchronizing switch is constituted of a synchronizing armature 52 attached to the rear surface of a shutter blade 53 and turned together with the shutter blade 53 and synchronizing contacts 36a and 36b which are arranged on the loci of the movements of both ends 52a and 52b of the synchronizing armature 52, on the surface of a synchronizing contact part 36 extended from a printed board 30 and consist of conductive patterns.

When the short circuit between the contacts 36a and 36b is obtained, an electric flash light emitting part 15 emits the light.  The timing of emitting the electric flash light is set by the angle of the synchronizing armature 52 with the synchronizing contact 36b, when the shutter blade 53 is in a closed position. Since the angle is not changed by external force, etc., the stroboscope can always emit the light at the exact timing.

Filed: 1987-08-19
Abstract: PURPOSE:To accurately discriminate the interference between objects even if they are very close, by approximating each solid body with a set of one or two or more polyhedrons and projecting constituting faces of polyhedrons to a two-dimensional plane and discriminating whether projected patterns overlap or not. CONSTITUTION:A work shape is approximated with a polyhedrons; and if this polyhedron has a recessed part like a work 31 shown in the figure, the polyhedron is divided into two projecting polyhedrons 32 and 33, and the shape of a sensor 34 is approximated with a set of projecting polyhedrons similarly. A work face 35 and a sensor face 36 are projected on a face having (x), (y), and (z) axes as normals in a work reference coordinate system Cw, and overlap between two projected patterns is checked on projection faces in respective axial directions; and if two patterns overlap each other on all of three projection faces, it is judged that there is much possibility of the interference between the sensor face and the work face. Thus, the interference is accurately discriminated by the three-axis projection method even if an original object has a recessed shape and another solid body is put in its recessed part.
