Title: Method for detecting position of body
Inventor: OOE AKIHIKO
IPC: G03F9/00
Filed: 1982-01-19
Abstract: PURPOSE:To detect the body whose angle is slightly deviated and whose position is slightly deviated, accurately in a short time, by using a random access type image pickup device, obtaining the maximum value among the integrated values of the rates of changes of the outputs obtained by performing the scanning in the directions of X axis and Y axis, obtaining the X and Y coordinates corresponding to that value so as to get the position expressed by the X and Y axes. CONSTITUTION:In consideration of the fact that there are many linear elements in an IC pattern, and by utilizing the characteristics that the random access type image pickup device can perform the zigzag scanning in the free directions, the edges of the body and the straight lines themselves can be detected as the variation in the products of the quantities of variations in a short time. Especially, in the case of the IC pattern, the position of each part of the pattern is accurately determined by an original drawing in advance by the preliminary learning of the sample pattern in order to keep repeating accuracy. Therefore the peak value, which can be clearly discriminated even though conditions are slightly expanded, can be selected.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce the resistance of an element by providing a p-type clad layer in which the carrier concentration of a ridge becomes steppingly higher than that of parts other than the ridge part as it is apart from an active layer. SOLUTION: When a voltage is applied so that a p-side electrode 13 becomes positive and an n-side electrode 14 becomes negative, holes and electrons are moved from the electrodes 13 and 14 respectively to an active layer 3, generating recoupling of light emission due to the holes and electrons injected into the active layer 3. Then A light generating in the active layer 3 is reflected between the end faces of a laser resonator and it is emitted as a laser light from the end face thereof. In this case, the upper part of ridge of a p-type clad layer is formed of p-type AlGaInP third clad layer 7 whose carrier concentration is higher than that of a p-type AlGaInP first clad layer 4, so that the upper part of ridge affecting the resistance of element is made to be low in resistance, and the resistance of element can be lowered.

Abstract: PURPOSE: To improve the reliability and simplify the construction of a pipe coupling, by combining an O-ring type packing with a cup-spring type lock ring.  
     CONSTITUTION: A conical packing box 21 of a pipe coupling 2 is fitted with an O-ring type packing 4 and further with a cup-spring type lock ring 5 made of corrosion-proof alloy and having a conical angle θ reducing outward. When a push ring 3 is screwed in the coupling 2, its push surface 31 presses against the lock ring 5 and causes an elastic deformation of the packing 4 for pressing toward the packing box 21 and the pipe 1 and then the outer circumference of the lock ring 5 is pressed toward a constaint groove 22, which increases the conical angle θ and the inner circumference encroaches upon the outer surface of the pipe 1.

Filed: 1986-01-17
Abstract: PURPOSE:To contrive high speed vector conversion processing by extracting all of the inflection points repeating the same process until a linear sequence of points and an outline sequence of points to a start point via an end point coincide. CONSTITUTION:Along a tracing direction 4 from a start point 2 to an end point 3, a control point 6 traces a border line points string 5, and the control point 6 continues a tracing when two kinds of direction vectors between adjacent two points on a boundary are present, and terminates the tracing when three kinds of them are present, and generates a linear sequence of points 9 between the start point 2 with a DDA method moving backward from a termination point, and when coinciding with an outline sequence of points 9A, a coincided point is extracted as an inflection point 8. Following that, the tracing is started from an extracted inflection point 8, and such process is repeated, and when a generated linear sequence of points and the outline sequence of points from the inflection point to the start point 2 via the end point 3 coincide, the extraction of the inflection point is completed. In this way, a processing time required for making an image pattern into vector can be remarkably reduced.

IPC: G06K9/46
Filed: 1990-01-19
Abstract: PURPOSE:To recognize a pattern at a high speed by applying (n X 3) pieces of data which are shifted by the 1st-3rd shift registers to an address terminal and then outputting these data in accordance with (n X 3) units of windows corresponding to those (n X 3) pieces of data. CONSTITUTION:The data to be recognized are applied to the cells 10-12 for each dot and converted via the parallel processing. That is, a 1st shift register 1 applies the input data to the cells 10 and 11 adjacent to each other and at the same time shifts these data in sequence. A 2nd shift register 2 receives data from an adjacent cell 10 and then shifts these data in sequence. Then a 3rd shift register 3 receives data from the adjacent cell 12 opposite to the register 2 and shifts these data in sequence. Furthermore a memory 4 applies (n X 3) pieces of data which are shifted by the registers 1-3 to an address terminal and then outputs the converted data corresponding to those (n X3) pieces of data. In such a constitution, a pattern is recognized at a high speed.

Title: Solid-state image pickup element
Inventor: ODA HIDETSUGU
IPC: H04N5/335
Filed: 1982-01-22
Abstract: PURPOSE:To eliminate exertion of direct effect of impurity distribution of a semicondutor substrate on the active region of a solid state image pickup element, by fomring  two epitaxial layers which are conduction type same as the substrate and have different levels of impurity density on said substrate and then forming an active region on  each epitaxial layer. CONSTITUTION:Two n type semiconductor layers 22 and 23 are formed on an n type  semiconductor substrate 21 by an epitaxial growing process. An impurity of higher  density is doped to the layer 22 compared with the layer 23, and the impurity density  of the layer 23 is approximately equal to that of the substrate 21. Then p wells 2 and 3  are formed on the layer 23, and an n type semiconductor region 5 forming a photodiode is formed on the well 3. When the adverse bais voltage is applied between the  wells 2 and 3 and the substrate 21, a depletion layer extends up to the layers 22 and 23  with the adverse bias voltage. Both the thickness and density of the layers 22 and 23 are selected so that the edge of the depletion layer stays within the layer 22 regardless of the working state. Thus the active layer of a solid-state image pickup element stays within the layer 22 and does not receive the direct effect of the impurity distribution of  the substrate 21. As a result, the swirl-shaped fixed pattern noise is eliminated.
