A method for manufacturing a honeycomb structure includes molding a ceramic raw material to manufacture honeycomb molded bodies. The honeycomb molded bodies are fired to manufacture honeycomb fired bodies. End faces of at least two of the honeycomb fired bodies are joined interposing a joining material between the end faces to manufacture honeycomb joined bodies each having a length larger than a length of each honeycomb fired body. Side faces of the honeycomb joined bodies are bonded interposing an adhesive paste between the side faces to manufacture an aggregated body of the honeycomb joined bodies. The adhesive paste is dried and solidified to manufacture a honeycomb block including the aggregated body. The honeycomb block is separated at the joining material into at least two honeycomb blocks.

A honeycomb structure includes a honeycomb block which includes at least one honeycomb fired body having a first end face side and a second end face side in a longitudinal direction of the honeycomb fired body. The honeycomb fired body includes a plurality of cell walls extending along the longitudinal direction to define cells. Either one of first and second end portions in the longitudinal direction of each of the cells is sealed. The first end portion provided on the first end face side of the at least one honeycomb fired body is sealed with a first plug which is made from a plug material paste and fired. The second end portion provided on the second end face side of the at least one honeycomb fired body is sealed with a second plug which is made from a plug material paste and unfired.

A honeycomb structure includes a honeycomb unit. The honeycomb unit includes plural cells, inorganic particles, and at least one of a flake substance, a tetrapod-shaped substance, and a three-dimensional needle-shaped substance. The plural cells extend from a first end face to a second end face of the honeycomb structure along a longitudinal direction of the honeycomb structure. The plural cells are defined by cell walls.

In the past, comparison of mean values or variances measured from multiple subjects with one another has been a mainstream of diagnostic support to be achieved using cerebral activity signals. However, in this case, it is hard to absorb individual differences, and the precision in a diagnostic support technology is low. In order to improve the precision in the diagnostic support technology, the property of data acquired by an optical organism measurement system is utilized in order to create and display information representing a change in the condition of each person. Thus, diagnosis of each person is effectively supported. Measured light signals are used to calculate and record changes in the concentrations of oxidized hemoglobin (Hb), deoxidized Hb, and total Hb respectively. Based on each data (representing the Hb concentration changes), two or more Hb concentration changes (for example, the oxidized Hb concentration change and deoxidized Hb concentration change) are classified according to whether the changes are increases or decreases, and indicated in the form of symbols, an image, or a graph. Thus, an examining person is provided with compressed and simplified information and supported in diagnosis.

A method for manufacturing a honeycomb structure includes molding a ceramic raw material to manufacture at least one honeycomb molded body having a plurality of cell walls to define cells. First cells and third cells are filled with plug material paste at first end portions and at third portions, respectively, to form first plugs. The at least one honeycomb molded body is fired to manufacture at least one honeycomb fired body. The at least one honeycomb fired body is cut along a plane substantially perpendicular to the longitudinal direction to create a second end face side of the at least one honeycomb fired body. Second end portions of second cells are filled with plug material paste. The plug material paste in the second end portions is solidified through heating to form second plugs. A honeycomb block including at least one honeycomb fired body is produced.

A honeycomb structural body includes honeycomb units that are pillar-shaped and bound together. Each of the honeycomb units includes plural cells, phosphate-based zeolite, and a first inorganic binder. The plural cells extend from a first end face to a second end face in a longitudinal direction of each of the honeycomb units. The plural cells are defined by cell walls. The mat members are interposed between the honeycomb units and include a first inorganic fiber.

A honeycomb structure includes a ceramic block including a plurality of honeycomb fired bodies, a first adhesive layer, and a second adhesive layer. The plurality of honeycomb fired bodies includes center-portion honeycomb fired bodies located at a center portion in a cross-section perpendicular to the longitudinal direction and peripheral honeycomb fired bodies surrounding the center-portion honeycomb fired bodies. The first adhesive layer is interposed between the center-portion honeycomb fired bodies to connect the center-portion honeycomb fired bodies. The second adhesive layer is interposed between each of the center-portion honeycomb fired bodies and each of the peripheral honeycomb fired bodies and between the peripheral honeycomb fired bodies. An adhesive strength α between the center-portion honeycomb fired bodies bonded via the first adhesive layer is higher than an adhesive strength β between honeycomb fired bodies bonded via the second adhesive layer.
