Abstract: There is provided an ink sheet cartridge, which is provided with a cartridge body, a supply-side core tube, a takeup-side core tube, and spools detachably attached to end portions of the supply-side and takeup-side core tubes, respectively, and at least one intermediate connector that is interposed between at least one of the spools and corresponding one of the end portions of the supply-side and takeup-side core tubes. The corresponding one of the end portions at which the at least one intermediate connector is interposed id formed with a female engagement portion. The ink sheet cartridge further includes a male engagement member that is fitted into the female engagement portion from the outside so that the at least one intermediate connector is engaged with one of the supply-side and takeup-side core tubes having the female engagement portion.

There is provided a catalytic combustion apparatus in which, by means of a combustion chamber 200 having a fuel supply portion 1 and a combustion air supply portion 2 on the upstream side thereof and a combustion gas exhaust port 4 on the downstream side thereof and a catalytic combustion portion 5 with an upstream surface and a downstream surface provided in the combustion chamber 200, the upstream surface and the downstream surface being substantially parallel to each other, a fuel-air mixture supplied to the interior of the combustion chamber 200 is caused to react to liberate heat.

Abstract: In a heat exchanger of the present invention for exchanging heat between fluid flowing in a flow passage in a heat exchanger tube and fluid flowing outside of said heat exchanger tube, a solid bar-like insertion member or a hollow bar-like insertion member whose opposite ends are closed is provided in said flow passage in which a fluid having phase change flows in gas-liquid two phase state or liquid phase state, a cross section of said insertion member is formed into a substantially circle shape, a polygonal shape or a starlike shape, and a cross-sectional area of a flow passage in which said fluid flows is reduced as a mass flow rate quality of said fluid is reduced. With this construction, it is possible to restrain the pressure loss at the time of evaporation, and the evaporation ability can be enhanced or can be restrained from being deteriorated.

Abstract: A structured document retrieval apparatus which fetches an objective document from many documents stored in a storage device. In the apparatus, a logical structure extraction unit extracts the logical structure, document attribute, and content of a structured document, and the extracted information is stored in a document information storage unit. Since the information is stored only in this unit, it is not necessary to conduct cumbersome duplicate management such that the matching of information is always maintained. In the retrieval, a logical structure decision unit checks a document to decide whether it has the same logical structure as that written in a retrieval expression or not. Only in a document having the same logical structure, a component (for example, author) which is the ultimate retrieval object of the document is first accessed to be retrieved.

Abstract: A structured data processor for processing tree-structured data. In the processor, inputted sequential data is arranged in the order of depth, and has depth information defined with respect to the root of the tree structure, i.e., the first data element in the order of depth. At the time the sequential data is converted into the tree-structured data at a data input unit, a structural position determining unit determines the structural position of the tree structure based on the structural depth information of the inputted sequential data. The positions of the data elements whose depths are equal to one another are determined in terms of the sequence of arrangement thereof within the depth.

Abstract: Disclosed is a heat exchanger having a plurality of flat fins disposed in parallel at predetermined intervals and adapted such that the air flows therebetween and a plurality of heat-transfer tubes disposed to intersect at right angles with the plurality of fins and adapted such that a fluid flows therethrough. The heat-transfer tubes are arranged such that a line connecting the adjacent heat-transfer tubes in the longitudinal direction of the fin is perpendicular to the direction of the air flow. The projection area in the direction of the air flow of any of the heat-transfer tubes located on the upstream side with respect to the air flow partially overlaps the position of at least one of the heat-transfer tubes disposed on the downstream side thereof. The pitch of adjacent heat-transfer tubes is smaller in the direction perpendicular to the air flow than in the direction of the air flow. Such an arrangement excells in both the frosting characteristics and performance.
