摘要: The invention discloses a macro lens that takes a retrofocusing function for the purpose of downsizing. The macro lens employs a floating mechanism to cover a wide photographing range from the equi-magnification to the infinity, and especially, attains a great imaging performance by appropriately compensating for spherical aberration, comatic aberration, and chromatic aberration of magnification. The macro lens comprised of first to fifth lenses in the order closer to the object; that is, the first lens serving as a negative meniscus lens with a convex surface oriented to the object, the fourth lens as a negative lens with a concave surface of great curvature oriented to the image plane, and the fifth lens as a negative lens with a surface of great curvature oriented to the object. The macro lens satisfies conditions as expressed in the following formulae: 0.6≦F/F≦1.3 (1) 0.9≦F4/F5≦1.5 (2) where F is a focal length of the entire lens system, F1 is a focal length of the first lens, F4 is a focal length of the fourth lens, and F5 is a focal length of the fifth lens.

摘要: A method of controlling operation of a loom machine by a computer equipped with a data input unit incorporating a display imparted with a function for generating a first list of weaving conditions at least for a weft insertion apparatus and a function for generating an alteration confirmation list when the conditions in the first list are altered. Upon inputting of data representing a desired fabric parameter, weaving conditions corresponding to the fabric parameter are selected from those previously stored in the computer, whereupon the selected weaving conditions are displayed in the first list. Before the selected weaving conditions are validated for controlling the loom operation, a confirmation list is again displayed for allowing the weaving conditions to be altered. When altered, the updated list containing the altered conditions is again generated for confirmation. When acknowledgement is input for the first list or the updated list, the corresponding weaving conditions in the list are transferred to a relevant controller. By generating the display for confirmation, alteration or change of the weaving conditions as desired can be reliably effectuated without suffering errors.

摘要: A compact and lightweight, high variable power zoom lens especially suitable for single-lens reflex digital cameras, which is 75 degrees or even wider in field angle at the wide-angle end, approximately 3 to 4 in F-number at the wide-angle end and approximately 6 to 7 at the telephoto end, and about 15× in variable power ratio. The zoom lens of four groups of lens pieces respectively exerting positive, negative, positive, and positive refractivities varies the power from the wide-angle end to the telephoto end as a result of the 1st and 2nd lens groups being split more, the 2nd and 3rd lens groups coming closer to each other, and the 3rd and 4th lens groups also coming closer to each other. The 3rd lens group has the leading set of lens pieces of positive refractivity closer to objects and the trailing set of lens pieces of negative refractivity, and the trailing set alone are moved to be orthogonal to the optical axis to compensate for defocus in the imaging plane caused by a tremor of the user's hand(s). The 2nd lens group are displaced closer to objects for the focusing.

摘要: The present invention is directed to a compact large-aperture-ratio inner-focusing telephoto zoom lens of the reduced total lens extension where minimizing a photo-shooting distance down to as short as 1 meter does not cause the lens optics to displace accordingly greater during the focusing. The large-aperture-ratio inner-focusing telephoto zoom lens has four groups of lens pieces, namely, the 1st lens group of positive refractive power, the 2nd lens group of negative refractive power, the 3rd lens group of positive refractive power, and, the 4th lens group of positive refractive power arranged in series on the basis of “closer to a subject first,” and that has the 2nd and 3rd lens groups moved along the optical axis to vary a magnification power. In such a telephoto zoom lens, the 1st lens group includes the leading subgroup of lens pieces or foremost lens subgroup G1F and the trailing subgroup of lens pieces or rear lens subgroup G1R where the G1F has two of a concave lens piece and a convex lens piece cemented into a single piece of composite lens while the G1R has a composite lens of one concave lens piece and two convex lens pieces in series. The rear lens subgroup G1R in the 1st lens group is moved along the optical axis for the focusing, and the telephoto zoom lens has an optical property that satisfies requirements as follows: 1.3

摘要: A industrial equipment can easily change display contents and setting contents. In the industrial equipment, a display setting unit which makes a screen display does not hold data for the screen display. According to an operation instruction from an operator, the display setting unit reads a corresponding display data file, generates screen data based on the display data file, and displays the data. The display contents and the setting contents can be changed by changing a corresponding display data file only.
