Title: Character recognizing method and device therefor
Inventor: SASAKI HIROSHI
IPC: G06K9/62
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To recognize characters with high segmentation accuracy by checking the mutual connecting relation between the codes of candidate character patterns having the adjacent relation in character string patterns. SOLUTION: This device includes an image input part 10, a candidate character pattern extraction part 12, a character recognition part 14, a candidate path production part 16 and a best result selection part 18. The part 16 reads a 1st character code out of a character code memory 22 for an extracted 1st candidate character pattern. In the same way, a 2nd character code is read out for a 2nd candidate character pattern that is adjacent to the 1st one. If the connecting relation between the 1st and 2nd character codes satisfies the connection rule that is previously set, the 1st character code is recorded in a path memory. Thus, it's possible to judge whether or not the characters form a candidate path by checking the connecting relation between the character codes of the candidate character patterns which are adjacent to each other in a character string pattern.

CONSTITUTION:An inlet valve 16 and an outlet 22 are opened to introduce Na flowing through main system piping 14 into a sampling apparatus. Na passes through inlet piping 18 to flow in the bottom part of a cup receiving container 12 to gradually rise while extrudes the gas in the container 12 from an outflow port 42 and reaches the upper part of the container 12 to flow in the gas sump part 46 on the lateral side of the container 12 from the outflow port 42. Na downwardly flows in the sump part 46 and, since the sump part 46 has a large flow passage cross-section area as compared with the outlet and inlet pipings 20, 18 and slow in a flow speed, gas is stored in the space of the sump part 46. Next, when the valves 16, 22 are closed and a bypass valve 48 is opened, Na in the container 12 except the interiors of cups 10 flows backward from the bottom part of the container 12 to enter the sump part 46 through a bypass pipe 50 and, with the inflow of Na, the gas in the sump part 46 contrarily enters the container 12 from the outflow port 42. By this method, Na in the container 12 is replaced with the gas in the sump part 46 and, after Na is solidified in the cups 10, a partition valve 32 is closed and the container 12 is detached at the places of pipe joints 34 to the subjected to analysis.

Title: Broad band equal beam array antenna
Inventor: HIDAKA KAZUTAKA
IPC: H01Q21/06
Filed: 1984-01-13
Abstract: PURPOSE:To obtain an equal beam width over a broad band by deciding the element interval and the element so that the product between the productivity of the element and the array factor is a constant value. CONSTITUTION:Three serial dipoles #1-#n are arranged in order up to the #n on the Z axis at an element interval (d) on the XZ plane while placing the #1 on the origin. Since the exciting current of the i-th element of the array is expressed in expression, the beam width of the array factor is increased as the frequency increases. the directivity F(theta,phi) of the array antenna is the product between the element directivity f(theta,phi) and the array factor D(theta). In order to make the directivity of the plane E of the antenna equal in the beam width, when the theta is fixed in a direction in the main beam, the product between the D(theta) and the f(theta,phi) is made independent of the frequency. In this case, in a series dipole comprising m-set of dipoles with an interval S, the increase in the (m) makes the negative gradient of the element directivity steep and the increase in (n) makes the positive gradient steep, then the values (m), (n) cancelling both positive and negative gradients are selected thereby realizing a broad band equal beam width array antenna.
