| 20110081173 | SEPARATION UNIT, FIXING UNIT AND IMAGE FORMING APPARATUS - A separation unit is provided on a downstream side of a contact area between a belt-like rotating body and a pressure rotating body. The separation unit includes a pressure member, a guide portion and a pressure portion. The pressure member extends along a width direction of the belt-like rotating body, and presses the belt-like rotating body to deform the belt-like rotating body into a bent shape changing a course away from a surface of the pressure rotating body. The guide portion is on the pressure rotating body side of the pressure member to guide the belt-like rotating body so that an angle portion of the bent shape bites into the pressure rotating body. The pressure portion is on the surface in the pressure rotating body side, and the surface separates sequentially from the pressure rotating body in the extending direction from a center portion to an end portion. | 04-07-2011 |

| 20100011920 | METHOD AND APPARATUS FOR MACHNING V GROOVES - There is provided a V-groove machining method and apparatus which, by measuring the depth of a V groove cut by a cutting tool and correcting the cutting depth of the cutting tool based on the measurement data, enables high precision machining of four-sided pyramids having vertices of a uniform height. The V-groove machining method includes the steps of: feeding a cutting tool relative to a workpiece in a first direction to create a first V groove, extending in the first direction, in the surface of the workpiece, and repeating this machining operation to create first V grooves at a predetermined pitch; moving the cutting tool along one of the first V grooves and scanning the first V groove with a distance sensor, disposed near the cutting tool, to measure the distance to the bottom of the first V groove, thereby detecting undulation of the bottom of the first V groove along the first direction; and feeding the cutting tool relative to the workpiece in a second direction orthogonal to the first direction to create a second V groove in the surface of the workpiece, and repeating this machining operation while correcting the position of the cutting tool in the machining position for each second V groove based on the results of detection of the undulation, thereby creating second V grooves at a predetermined pitch. | 01-21-2010 |

| 20120200629 | PRINTING METHOD AND PRINTING APPARATUS - A plurality of images is sequentially printed on a sheet, and the sheet is cut at a cut position that is behind the finally-printed image. At that time, if an inappropriate region of the fed sheet that is not suited to printing is detected, and the detected inappropriate region is behind the finally-printed image, the cut position is changed to be behind the detected inappropriate region. | 08-09-2012 |

| 20090302532 | CONVEYANCE APPARATUS, CONTROL METHOD THEREFOR, AND PRINTING APPARATUS - A conveyance apparatus increases the conveyance precision of a conveyance unit. The conveyance apparatus has first and second conveyance rollers. The conveyance apparatus includes a DC motor serving as a driving source for the conveyance rollers, a first encoder which outputs a first pulse signal in accordance with rotation of the first conveyance roller, a second encoder which outputs a second pulse signal in accordance with rotation of the second conveyance roller, and a control unit having a first mode in which the DC motor is controlled based on first information about the first pulse signal when executing a conveyance operation to convey a sheet by using the first and second conveyance rollers, and a second mode in which the DC motor is controlled based on second information about the second pulse signal when executing a conveyance operation to convey a sheet by using the second conveyance roller. | 12-10-2009 |
| 20100266321 | PRINTING APPARATUS, CONVEYANCE APPARATUS, AND FEED-CONVEYANCE CONTROL METHOD - This invention relates to an apparatus and method capable of appropriately preventing a printing medium from being diagonally conveyed upon feed regardless of changes in printing medium feed conditions. In this invention, the maximum output value of a PWM signal is compared with the sum of a predetermined bias value and the PWM signal when a sensor detects the tip of a fed printing medium. If the sum is smaller than the maximum output value, it is monitored that the value of the PWM signal increases by the bias value. If the sum is equal to or larger than the maximum output value, it is monitored that the conveyance speed of the printing medium becomes smaller than a predetermined threshold value. Control is performed on the basis of the monitor results to stop driving a DC motor that supplies a driving force to rollers used for feed and conveyance. | 10-21-2010 |

| 20100242693 | CUTTING-EDGE POSITION DETECTING METHOD AND CUTTING-EDGE POSITION DETECTING APPARATUS - The cutting-edge position detecting method includes the steps of: under a condition in which the cutting edge of the tool is positioned in an image that is taken by a camera, performing first sampling scanning operations for the image in a predetermined scanning direction at predetermined first intervals, and recognizing points on an upper edge line of the cutting edge of the tool and points on a lower edge line thereof, based on brightness changing points upon the first scanning operations; connecting the recognized points on the respective two edge lines, so as to obtain two first-level approximate linear lines by a least-squares method; performing second sampling scanning operations for the respective two first-level approximate linear lines in directions perpendicular thereto at predetermined second intervals, and newly recognizing points on the upper edge line of the cutting edge of the tool and points on the lower edge line thereof, based on brightness changing points upon the second scanning operations; connecting the newly recognized points on the respective two edge lines, so as to obtain two second-level approximate linear lines by a least-squares method; and obtaining a coordinate of an intersection of the second-level approximate linear lines, as the position of the cutting edge of the tool, with respect to the measurement reference point. | 09-30-2010 |
| 20110217905 | GRINDING MACHINE HAVING THE FUNCTION OF MEASURING DISTANCE - The invention relates to a grinding machine for grinding a workpiece, which has been set on a chuck top surface, by moving a rotating grinding wheel in relation to the workpiece. The grinding machine includes: a microscope configured to be vertically movable; a CCD camera configured to take an image viewed through the microscope; and an image processor configured to process the image taken by the CCD camera to measure a vertical distance between a reference plane of the microscope and an object of the microscope. The image processor is adapted to measure the vertical distance between the reference plane of the microscope and the object of the microscope based on sharpness of the image, which corresponds to how clear the microscope is focused. | 09-08-2011 |
