| 20100245576 | CALIBRATING APPARATUS FOR ON-BOARD CAMERA OF VEHICLE - There is provided a calibrating apparatus for an on-board camera of a vehicle, which allows speedy, yet reliable decision of acceptance/rejection of calibration result, with a simple apparatus construction, without depending on or being influenced by the calibration environment. An image processing target region on which an image processing for detection of each calibration point in each one of calibration markers in a camera-captured image which is a projecting plane of a camera coordinate system is displayed as a region frame in the form of a graphic image, in superposition with the camera-captured image. | 09-30-2010 |
| 20100245592 | CALIBRATING APPARATUS FOR ON-BOARD CAMERA OF VEHICLE - Provided is a calibrating apparatus for an on-board camera of a vehicle, which apparatus allows completion of calibration process with a simple additional calibration, even when rejection has issued on the result of automatic calibration. Based upon a camera parameter obtained at the time of completion of adjustment by an automatic adjusting section, a confirmation marker indicating the position of coordinate of a calibration point is displayed in superposition with a camera-captured image. A manual adjusting section adjusts the camera parameter, based on an amount of displacement of the coordinate of the calibration point corresponding to an amount of movement of the confirmation marker moved in response to input of adjustment instruction. In response to input of a determination instruction, a camera parameter setting section sets an undetermined camera parameter at the time of completion of the most recent adjustment by the automatic adjusting section and the manual adjusting section, as the camera parameter. | 09-30-2010 |

| 20090101247 | Method for producing martensitic stainless steel pipe - A martensitic stainless steel pipe, which comprises specified quantities of C, Si, Mn, P, S, Cr, Ni, Al, N, Cu, Ti, V, Mo, Nb, B and Ca, and the balance being Fe and impurities, has satisfactory toughness at a high strength of 650 MPa or more by yield strength and also excellent hot workability. Therefore, it can be used as a high-strength martensitic stainless steel pipe for carbon dioxide gas corrosion resistant use, to be used in oil and/or gas well environments containing no hydrogen sulfide but carbon dioxide gas. This high-strength martensitic stainless steel pipe is an inexpensive martensitic stainless steel pipe, which does not require an addition of large quantities of expensive elements such as Ni and Mo, and moreover does not require the control of the content of P to a value less than 0.010% by mass. | 04-23-2009 |
| 20100078936 | THREADED JOINT FOR STEEL PIPES - A threaded joint for steel pipes constituted by a pin having male threads and a box having female threads is improved with respect to ease of insertion of the pin and galling resistance of the threaded portions. The stabbing flanks of the threads in a complete thread portion of one of the pin and a box has a two-step stabbing shape having a chamfer. The two-step stabbing shape has a stabbing flank angle α of 5-45° and a chamfer angle β of 20-60°. The ratio h/H of the chamfer height h to the thread height H of the pin is 0.25-0.50, or the ratio of the cross-sectional area of the chamfered portion to the overall cross-sectional area of the stabbing flank is made at least a value corresponding to a chamfer height ratio h/H of 0.25 and at most a value corresponding to a chamfer height ratio of 0.50. | 04-01-2010 |
