摘要:
A honeycomb structure includes a ceramic block including honeycomb fired bodies. The honeycomb fired bodies include an assembly including a plurality of substantially quadrangular-cross-section units which are combined with one another with an adhesive layer interposed between the plurality of substantially quadrangular-cross-section units. A peripheral face of the assembly of substantially quadrangular-cross-section units has a concave portion and a convex portion formed in a substantially step-shaped pattern. At least one substantially triangular-cross-section unit has an outer wall on a periphery portion of the at least one substantially triangular-cross-section unit. The at least one substantially triangular-cross-section unit is fit in the concave portion with the adhesive layer interposed between the at least one substantially triangular-cross-section unit and the concave portion. A sealing material layer is provided on a peripheral face of the ceramic block. The sealing material layer has partially different thickness.

A honeycomb structure includes a ceramic block. A plurality of honeycomb fired bodies include first-shaped units, second-shaped units, and third-shaped units. The first-shaped units include peripheral first-shaped units. Each of the peripheral first-shaped units is disposed in such a manner as to have two sides. One side of the two sides faces one of adjacent sides of one third-shaped unit among the third-shaped units with an adhesive layer therebetween. Another side of the two sides faces one of adjacent sides of another third-shaped unit among the third-shaped units with the adhesive layer therebetween. The two sides of each of the peripheral first-shaped units or extensions of the two sides are each neither substantially parallel nor substantially perpendicular to an extension of a second side and an extension of a first side of each of the second-shaped units.

An object of the invention is to prevent an oil from penetrating into a vessel obtained from expandable thermoplastic resin beads through molding. The above object is achieved by expandable thermoplastic resin beads whose surface or surface layer is coated or incorporated with a fluorine-containing block copolymer comprising of a fluorine-containing vinyl-type polymer segment derived from a fluorine-containing vinyl-type monomer and a lipophilic vinyl-type polymer segment derived from a lipophilic vinyl-type monomer.

Physiologically active substance NK175203 is produced by culturing bacteria belonging to the genus Streptomyces and capable of producing the physiologically active substance NK175203, and collecting the produced and accumulated substance. The physiologically active substance NK175203 is useful as an effective ingredient of a pharmaceutical composition for promoting proliferation of bone marrow cells.

A flexible tube for an endoscope includes a spiral coil 11 as the innermost layer and a jacket 13 that is formed by applying a melt of a jacket material 1 and then curing it, in which the jacket material 1 has been allowed to penetrate through the gaps between adjacent turns of the innermost spiral coil 11 to reach the portion of its inner surface.

A honeycomb structure includes a ceramic block including honeycomb fired bodies. The honeycomb fired bodies includes at least one first-shaped unit having a substantially quadrangular shape in a cross section perpendicular to the longitudinal direction. At least one second-shaped unit has a shape that includes at least a first side, a second side making a substantially right angle with the first side, and an inclined side facing the substantially right angle in the cross section. The at least one second-shaped unit is located in a peripheral portion of the ceramic block and is disposed with the second side adjacent to the at least one first-shaped unit. The second side forming a periphery of the at least one second-shaped unit is longer than a longest side of four sides forming a periphery of the at least one first-shaped unit in the cross section.
