Title: Feature data extraction method for closed curve and matching method using the same
Inventor: FUJIWARA NOBUYUKI
IPC: G06T7/00
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a feature data extraction method for extracting the feature data of the closed curve so as to utilize the curve feature of an object. SOLUTION: The closed curve is divided into a 'large closed curve' and a 'small closed curve' by the number of points for constituting closed curve data which are the set of the respective points provided with three-dimensional coordinates as data (S11). In the case of the 'large closed curve', the equivalent ellipse is calculated (S12 and S13) and the data of the equivalent ellipse or the like are extracted as the feature data (S14 and S15). Also, in the case of the 'small closed curve', a rectangle for which respective sides surrounding it are parallel to an axis is calculated and the center position of the rectangle is extracted as the feature data (S16).

Title: Both-surface aspherical lens
Inventor: SHINOHARA SHUNEI
IPC: G02C7/02
Filed: 1990-04-17
Abstract: PURPOSE:To improve the outward appearance and performance by forming an aspherical surface which decreases in the difference in curvature between the peripheral parts on the front and rear surface sides by varying the curvature at the peripheral parts while maintaining specific degrees. CONSTITUTION:The aspherical surface is formed which decreases in the difference in curvature between the peripheral parts on the sides of the front surface 1 and rear surface 3 by varying the curvature while maintaining the specific degrees at the peripheral parts on the sides of the front surface 1 and rear surface 3. For example, a minus lens is therefore larger in curvature at the peripheral part of the front surface 1 than at the peripheral part of the rear surface 3 and small in edge thickness. A plus lens, on the other hand, is small in curvature at the peripheral part of the front surface 1 and large at the peripheral part of the rear surface 3, so the lens has rising section and becomes flat on the whole, so that the quantity of forward projection of the lens becomes small. Consequently, the outward appearance is improved, respective aberrations which can not be removed by the front aspherical surface can be corrected by the rear aspherical surface, and the optical performance of the lens can be improved.

Title: Electromagnetic type underground inspection
Inventor: OSHIMA HIROYUKI
IPC: G01V3/12
Filed: 1987-04-27
Abstract: PURPOSE:To simplify measuring work, by a method wherein a survey side track is divided into a plurality of sections to calculate a section impedance between sections and a spatial filter computation is performed from the resulting number of waves to determine an apparent specific resistance or a true specific resistance from the results. CONSTITUTION:A survey side track S is divided into a plurality of sections S1-Sn to measure position data between the sections. Fluctuating potential differences DELTAVi between the sections are measured simultaneously with remote site stations 31-3m for measuring potential differences as for multiple sections. Magnetic field sensors 4x and 4y are arranged near the line S to measure horizontal two components of fluctuating magnetic field. Then, fluctuating electric fields between sections are determined from the potential differences DELTAVi. A spatial impedance is calculated from these fluctuating magnetic fields and fluctuating electric fields and a spatial filter operator is determined from a wave number thus obtained to perform a spatial filter computation. Then, from the results, an apparent specific resistance or a true specific resistance is determined. This inspection method permits measurement only limited to one direction of electric field and two directions of magnetic field thereby simplifying measuring work.

IPC: G11C17/00
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a non-volatile memory cell having the array of memory cells of single transistor to be read according to an improved read cycle operation. SOLUTION: Concerning a selected cell 12 to be mutually connected through a single bit line 16 to the other cell, the activity required for identifying the programmed or non-programmed state of that cell 12 is guaranteed. Concerning the non-selected cell to be connected to the selected cell, inactivity is advantageously guaranteed by impressing a negative voltage to a word line 20 related to these cells. This negative voltage is lower than a threshold voltage related to the MOS device of single transistor. Therefore, the non-selected cell is kept inactive and the single active or inactive selected cell usually depending on the programmed state of array is applied. With the negative voltage loaded to the non-selected cell, the leak of over erased cells always related to a depression type operation is minimized.
