20100148803 | PASSAGE DETECTION APPARATUS OF OBJECT - A passage detection apparatus is configured to detect the change in the properties (propagation state of sound wave, dielectric constant, etc.) of a specific space, which changes according to the passage of an object in the specific space and the size of the object. The passage detection apparatus includes a pair of detection units and configured to transmit and receive signals to and from an external device. The specific space is formed by the space between the detection unit and the detection unit. The detection unit is supported by a first substrate. The detection unit is supported by a second substrate that is parallel to the first substrate, and arranged at the position corresponding to the detection unit supported by the first substrate. | 06-17-2010 |
20110070396 | HONEYCOMB STRUCTURE AND METHOD FOR MANUFACTURING THE SAME - A honeycomb structure | 03-24-2011 |
20110076443 | HONEYCOMB STRUCTURE AND METHOD FOR MANUFACTURING THE SAME - A honeycomb structure includes porous partition walls via which a plurality of cells constituting through channels for a fluid are partitioned; and an outer peripheral wall positioned in the outermost periphery of the structure. Open frontal areas of predetermined cells in an end face of the structure on a fluid inlet side thereof and open frontal areas of remaining cells in an end face of the structure on a fluid outlet side thereof have plugged portions. The outward end faces of the plugged portions are flat, the plugged portions do not have any bubble having a diameter of 0.3 mm or more, and a value obtained by dividing the standard deviation of the plugging depths of the plugged portions by the average plugging depth of the plugged portions is 0.15 or less. | 03-31-2011 |
