  • Patent number: 6476913
    Abstract: Inspection method, apparatus, and system for a circuit pattern, in which when various conditions which are necessary in case of inspecting a fine circuit pattern by using an image formed by irradiating white light, a laser beam, or a charged particle beam are set, its operating efficiency can be improved. An inspection target region of an inspection-subject substrate is displayed, and a designated map picture plane and an image of an optical microscope or an electron beam microscope of a designated region are displayed in parallel, thereby enabling a defect distribution and a defect image to be simultaneously seen. Item names of inspecting conditions and a picture plane to display, input, or instruct the contents of the inspecting conditions are integrated, those contents are overlapped to the picture plane and layer-displayed, and all of the item names are displayed in parallel in a tab format in the upper portion of the picture plane of the contents.

  • Publication number: 20020045813
    Abstract: A method for processing biomagnetic fields generated by biocurrents resulting from activities of human brain or myocardia and its mapping apparatus are provided, which features biomagnetic measurement and its analysis, magnetic field mapping and its imaging and their waveform generation by a simple operation. Biomagnetic fields emitted from the patient are measured at a plurality of measurement positions, and a contour map of magnetic field obtained as a result of processing of these measured biomagnetic fields is imaged in the magnetic contour map display apparatus, which display apparatus comprises: the process function display area indicating process function items including measurement; and the analysis data display area which displays the waveform together with a designated measurement time, the waveform being generated during measurement at least based on the measured biomagnetic fields and during the designated measurement period of time.

  • Publication number: 20020031444
    Abstract: An operation guidance method of clinical system which enables a doctor or nurse unskilled in testing to operate the clinical system without operation error by providing operation guidance. In the system, an initial screen shows numerals 1 to 5 indicating the order of procedure of sample test and character information indicating the contents of works (1 confirmation of sample, 2 confirmation of request, 3 feeding samples, 4 confirmation of result and 5 finish) as contents displayed in an operation menu. When an operator selects a “start” button, display images showing as guidance on the respective works are sequentially displayed. Further, a display image as guidance on arbitrary one of the works may be displayed by selection of one of the works in the operation menu.
