Patent number: 5061074Abstract: An apparatus for inspecting the top and bottom surfaces of a tape or sheet has a device to magnify the surface of the tape or sheet, with its objective lens disposed to face the top surface of the tape or sheet. The apparatus also has an optical transmittion system that transmits an image of the bottom surface of the tape or sheet through a focusing unit and four reflectors, each of which is adapted to bend the path of light rays 90 degrees. Of the four reflectors, one that faces the objective lens is retractable from the light-ray path in the optical transmission system. The reflector facing the objective lens may be a half-coated mirror. Fixed in the light-ray path in the optical transmission system, the half-coated mirror is not retractable.Type: GrantFiled: October 17, 1989Date of Patent: October 29, 1991Assignee: Nippon Steel CorporationInventors: Naoharu Ohikata, Toshiro Matsubara, Jiro Ohno

Patent number: 4641083Abstract: A method and apparatus for supervising a descending speed, thickness of a layer, particle size, and so on of charges in a blast furnace. Coke and ore composing the charges are detected by radiating an electromagnetic wave into the blast furnace. An electromagnetic wave can easily pass through coke, but is reflected or scattered by ore.Type: GrantFiled: August 1, 1983Date of Patent: February 3, 1987Assignee: Nippon Steel CorporationInventors: Jiro Ohno, Hirokatsu Yashiro

Patent number: 4641036Abstract: A method of imaging the surface of an object at high temperature includes the steps of: irradiating the surface of a high-temperature object with two different kinds of pulses of monochromatic light of a fundamental wave and a harmonic thereof; passing the reflected light from the surface of the object through both an interference filter which allows only the two different kinds of monochromatic light to pass and a high-speed optical switch thereby to remove any background light component; drawing out only the reflected light of the pulses and leading the same to an image generating mechanism where it is converted into an image; and controlling the voltage applied to the high-speed optical switch thereby to adjust the mixing ratio between two wavelengths.Type: GrantFiled: September 21, 1984Date of Patent: February 3, 1987Assignee: Nippon Steel CorporationInventors: Jiro Ohno, Hirokatsu Yashiro
