  • Publication number: 20240113810
    Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

  • Patent number: 8499527
    Abstract: The present invention provides a building construction method and a room module which can realize reduction in a construction period in addition to reduction in an on-site working amount by further enlarging a room modularization range. The present invention uses four column members which are vertically provided at inner corners of four room modules adjacent to one another as a frame column of the building when a plurality of room modules are installed in a grid pattern on a floor surface of the building. Specifically, the present invention uses the column member of an angular steel pipe, which the room module has, as the frame column of the building. Thereby, on a construction site, it is not necessary to construct the frame column in advance, and the frame column can be constructed by using the column members of the room module while the room module is installed on the site.

  • Patent number: 7862758
    Abstract: An in-mold coating method for molding a molded product with an excellent external appearance. A resin molded product is kept pressed against a mold cavity surface until immediately before coating. Mold-clamping force in a second step in which the shape of the resin molded product is fixed and that in a fourth step are selected so that the deformation of the mold cavity by the mold-clamping forces is substantially the same in the second and fourth steps. Even if the mold cavity deforms by the mold-clamping force in the second step, the mold cavity deforms similarly in the fourth step to provide a uniform coating thickness. Alternatively, a mold-clamping force smaller than that in the first step is selected for the second step to reduce the degree of deformation of the mold cavity and to achieve a uniform coating thickness.
