20090200159 | REACTIVE SPUTTERING METHOD - In a reactive sputtering apparatus, an inert-gas supplying hole is provided in a movable target unit whose one end is open and whose conductance is controlled, and a reactive gas containing at least fluorine or oxygen can be supplied to a space between the target and a substrate. The apparatus is constructed so as to emit the reactive gas toward the substrate. A reactive-gas emitting location is in the space between the target and the substrate such that a concentration of the reactive gas on the substrate surface can be maintained at a higher level. When the target is moved, a reactive-gas emitting port is moved or the reactive-gas emitting location is changed. The concentration of the reactive gas on the substrate surface can be effectively kept constant, and a high-quality optical thin film can be formed. | 08-13-2009 |
20130025898 | FASTENING TOOL - A fastening tool is provided that incorporates, in an outer annular body into which a first nut is inserted to03 be driven to rotate, an inner annular body into which a first nut and a second nut having a pitch different from the pitch of the first nut are inserted to be driven to rotate, and that simultaneously rotates the two nuts and fastens the nuts to a bolt. A flange shaft body is driven to rotate relatively to the outer annular body and the inner annular body via a plurality of balls. The balls are held by the flange shaft body and pressed towards notches of the outer annular body and the inner annular body with urging forces of first and second urging members via holding members respectively. | 01-31-2013 |
20130135484 | IMAGE CAPTURING UNIT, COLOR MEASURING DEVICE, IMAGE FORMING APPARATUS, COLOR MEASURING SYSTEM AND COLOR MEASUREMENT METHOD - An image capturing unit includes a sensor unit that image-captures a predetermined area including a subject; and a reference chart unit that is arranged in the predetermined area and captured with the subject by the sensor unit. | 05-30-2013 |
20130208289 | COLOR MEASURING DEVICE, IMAGE FORMING APPARATUS, COLOR MEASURING METHOD, AND COLOR MEASURING SYSTEM - A color measuring device includes a unit configured to calculate a reference-value matrix for converting imaged reference RGB value of a reference color patch a reference colorimetric value of the reference color patch; a unit configured to convert a color-measurement RGB value of a color measurement object into an imaged colorimetric value of the color measurement object by using the corresponding reference-value matrix; a unit configured to select reference color patches of which the reference colorimetric values each have a close distance from the imaged colorimetric value in the predetermined color space; a unit configured to select, as selection RGB values, the imaged reference RGB values of the selected patches; a unit configured to calculate a selection-RGB-value matrix for converting the selection RGB values into the reference colorimetric values; and a unit configured to convert the color-measurement RGB value into a colorimetric value by using the selection-RGB-value matrix. | 08-15-2013 |
20130229671 | IMAGE CAPTURING UNIT, COLOR MEASURING DEVICE, IMAGE FORMING DEVICE, COLOR MEASURING SYSTEM, AND COLOR MEASURING METHOD - An image capturing unit includes a sensor section that images a predetermined range including a subject; a reference chart section that is imaged by the sensor section with the subject; and an illumination light source that illuminates the subject and the reference chart section. The illumination light source is arranged at a position where a mirror reflection region that mirror reflects light entering from the illumination light source to the sensor section is outside a region of the subject and the reference chart section. | 09-05-2013 |
20130242319 | IMAGING UNIT, COLOR MEASURING DEVICE, IMAGE FORMING APPARATUS, COLOR MEASURING SYSTEM, AND COLOR MEASURING METHOD - An imaging unit includes a frame having an opening; a sensor unit that captures, via the opening, a subject located outside the frame; a reference chart unit that is arranged on the frame and is captured by the sensor unit together with the subject; and a cover member that covers the opening. | 09-19-2013 |
20130242320 | IMAGE CAPTURING UNIT, COLOR MEASURING DEVICE, IMAGE FORMING APPARATUS, COLOR MEASURING SYSTEM, AND COLOR MEASUREMENT METHOD - An image capturing unit includes: a sensor unit that captures an image of a predetermined area including an image capture object; a reference chart portion that is disposed in the predetermined area and an image of which is captured together with an image of the image capture object by the sensor unit; an illumination light source that illuminates the image capture object and the reference chart portion; and a specular reflection preventing member that prevents that specular reflection light of light emitted from the illumination light source enters the sensor unit. | 09-19-2013 |
20130242321 | IMAGE CAPTURING UNIT, COLOR MEASURING DEVICE, IMAGE FORMING DEVICE, COLOR MEASURING SYSTEM, AND COLOR MEASURING METHOD - An image capturing unit includes a sensor unit that captures a predetermined area including a subject; a reference chart that is arranged in the predetermined area and captured together with the subject by the sensor unit; an optical path length changing member that is arranged on an optical path extending from the subject to the sensor unit and is capable of changing a length of the optical path. | 09-19-2013 |
20130242361 | IMAGE CAPTURING DEVICE, COLOR MEASURING DEVICE, COLOR MEASURING SYSTEM, IMAGE FORMING APPARATUS, AND COLOR MEASURING METHOD - An image capturing device includes a sensor unit that captures a predetermined range including a subject; a reference chart that is captured by the sensor unit together with the subject; an illumination light source that illuminates the subject and the reference chart; a lens member including one or more lenses arranged in an optical path of reflected light extending from the subject and the reference chart to the sensor unit; and a lens moving unit that moves at least one lens of the lens member so as to change a position thereof in a direction along the optical path. | 09-19-2013 |
