Inventor: SANO EMIKO
IPC: G01N33/50
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To measure neutrophil migration activity of neutrophil chemotactic factor, by using peritoneal exudate neutrophil of stimulus inoculated animals, and quantifying the neutrophil which migrationally fell down from an upper room of a migrational chamber to a lower room containing a chemotactic factor in colorimetric determination method using a hemocyte measuring device (MTT). SOLUTION: Gradually diluted chemotactic factors are put on the lower chamber divided with the migrational membrane using 2 wells per dilution, and objects which have no chemotactic factor, and fMLPs as a positive control are put on it by two wells respectively. In the test of neutrophil migration, not only culturing place of animal cells but also saline solution are used. The neutrophil of rabbits and others gathered from a peritoneum for measuring migration capacity is cleaned with saline solution and used. Cell buoyant liquid which is adjusted to specific concentration is put into the upper room, and is migrated in a carbon dioxide incubator at prescribed temperature for 30-60min., and the number of cells which migrationally fell down to the lower chamber is counted.  The migrating cells are measured using colorimetric determination method with a colter counter or a measuring device for number of hemocytes.

Title: Foreign article-inspecting apparatus
Inventor: MAEDA HIDEAKI
IPC: B65B57/10
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To suppress fatigue of inspector's eyes and improve inspection accuracy and inspection efficiency, by transferring a container in an overhung state on a conveyor, and inspecting the container while being illuminated by a light guide emitting parallel beams. SOLUTION: A chuck 34 of each container-holding mechanism 26 is opened at an upstream end of a conveyor 22. A neck part of a container 38 transferred in a horizontally laid state is inserted between the chucks 34 and carried on in an overhung state in association with the movement of the conveyor 22. At an inspection area, since a guide groove 66 is lower, a front end of a rotary shaft 30 is inclined upward and the container 38 is inclined with the neck part directed down. As a result, a liquid agent contained in the container 38 flows. If a foreign article is mixed inside, the foreign article flows towards a cap and is easily confirmed owing to parallel beams projected from downward by a light guide 71. Since there is set only a magnifier 81 below the container 38, nothing obstructs a view field and the foreign article can be discovered with ease even if it is very small.

Title: Table recognizing device
Inventor: KAMIMURA YUJIRO
IPC: G06K9/20
Filed: 1992-12-25
Abstract: PURPOSE:To prevent a dotted line from being extracted at a half tone part by mistake and to enable exact table recognition by determining dotted-line candidates in consideration of the accumulation of a histogram on the basis of a table image inputted from a scanner. CONSTITUTION:Runs which are longer than specific length among runs in the longitudinal and lateral directions of the table image inputted from the scanner 41 are connected to extract solid ruled lines. Then a rectangle of connected black pixels circumscribed with the image in the part encircled with the extracted ruled lines is extracted. Pixels constituting a broken line and a dotted line are smaller in with perpendicular to the length direction of the lines than other parts, so pixels which are less in width than a certain value in the extracted circumscribed rectangle are selected to generate a historgram of the frequencies. Parts which are larger than a threshold value are searched for, histograms in certain ranges on both sides are accumulated, and parts which are less than the threshold value are employed as dotted-line candidates.

Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To guarantee distribution of comfortable, safe braking action by reducing the difference set between front wheel braking pressure and rear wheel braking pressure when a specified condition that can be set comes into existence. SOLUTION: A signal of a wheel rotating speed sensor is supplied to a control unit 102.
