Title: Oxide superconductor and magnetic shield using the superconductor
Inventor: YAMADA SHUYA
IPC: C04B35/00
Filed: 1989-12-28
Abstract: PURPOSE:To obtain the superconductor having high critical current density by specifying the resistance of a polycrystalline oxide superconductor consisting essentially of rare-earth element-Ba-Cu-O toward the intrusion of a magnetic flux resulting from an effective magnetic field. CONSTITUTION:The polycrystalline oxide superconductor consists essentially of the material shown by formula I (RE is rare-earth elements). The intrusion of a magnetic flux resulting from an effective magnetic field into the superconductor at 77 deg.K is caused in the magnetic field at >=100 G. The superconductor has a high critical current density of >= about 3000A/cm<2>. Meanwhile, the degree of orientation of the superconductor shown by equation II (P (oriented sample) by equation III and P0 (unoriented sample) by equation IV) in the X-ray chart is preferably controlled to >=0.4, and high magnetic field and critical current density are exhibited as the degree of orientation is increased. Furthermore, the magnetic shielding effect is further increased by using this oxide superconductor for a magnetic shield, and the reliability in measurement of various measuring instruments is enhanced.

IPC: G06T3/60
Filed: 1989-12-28
Abstract: PURPOSE:To execute image data editing for a comparatively easy luster image at high speed by making a luster image to be a vector data, executing a coordinate transformation processing to the obtained vector data in accordance with the editing content, and extending the image after editing based on the vector data after the coordinate transformation. CONSTITUTION:A 1st data conversion part 20 which converts the luster image data which is the object of editing, into the vector data, a 2nd data conversion part 22 which converts the vector data into the luster image data, and a coordinate transformation part 24 which executes the coordinate transformation to the vector data are connected to an image data editing processing control part (control part) 17. In such a case, after the luster image data which is the subject of processing is converted into a vector data, the coordinate transformation in accordance with the editing processing is executed. The simpler the luster image which is the object of the processing to the vector data, the processing time necessary for the processing for data vectorization is shortened, and because the amount of data becomes less, the processing time necessary for the coordinate information becomes shorter. Thus, the editing processing is executed at high speed.

Title: Method for recognizing white line on road
Inventor: YAMADA KENICHI
IPC: G06T7/00
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To recognize a white line on a road more accurately. SOLUTION: The density of the entire pixels of an original image is differentiated by an image picking up means 1 and, the density differential value is further binarized to form a differential binarized image(steps S1 to S3). It is determined whether two edges exist in the differential binarized image with an interval that is within a prescribed length separated in a scan line direction, a line segment connecting both edges is extracted as a road white line candidate segment when they exist (step S4). Then, reference segments L and R of the same length are set at the both sides of the white line candidate segment C (step S5), and the density means value YC of each pixel on a segment in the original image which corresponds to the segment C is contrasted with the similar density mean values YL and YR about both reference segments L and R.  When YL≈YR and (YC-YL)>K and (YC-YR)>K hold, this white line candidate segment is determined as existing on an actual white line image and is registered as a real candidate for a white line (steps S6 YES and S7), where, K represents a reference value.
