Abstract: PURPOSE:To obtain the wide-angle, compact zoom lens system which has a >=X4 zoom ratio by allowing an optical system consisting of four lens groups which have a positive, a negative, a positive, and a positive refractive index successively from an object side to meet specific requirements. CONSTITUTION:When the zooming lens system is in zooming operation from the wide-angle terminal to the telephoto terminal, the 1st, the 3rd, and the 4th lens groups G1, G3, and G4 move linearly toward the object side on the optical axis and the 2nd lens group G2 moves nonlinearly associatively with the motion of other three lens groups to fix an image point. This lens system meets the requirements shown by inequalities I -V, where f1, f2, f3, and f4 are focal lengths of the 1st - the 4th lens systems G1, G2, G3, and G4, fW and fT are the focal length of the whole system at the wide-angle terminal and the focal length of the whole system at the telephoto terminal, and (e) is the width of deviation of the nonlinear movement track of the 2nd lens group G2 for power variation from the linear movement track.

Filed: 1982-05-08
Abstract: PURPOSE:To perform easily repairing of a weld zone in an early stage, by inspecting a welded part after every stage, and if any defect exists, indicating the size and coordinate position. CONSTITUTION:When an automatic welding machine 3 competes a stage of welding, an ultrasonic inspecting device 4 is moved to the inspectin start position by a command sent from a computer, and starts inspection. An ultrasonic probe 16 scans the whole area of the weld zone 21 welded along the weld line 5 which is in contact with the surface of a flat plate 2, and inspects the state of welding.
