Publication number: 20240113810Abstract: 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.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Inventors: Yutaka MURAKAMI, Shutai OKAMURA, Kiyotaka KOBAYASHI, Masayuki ORIHASHI, Kazuaki TAKAHASHI

Patent number: 7862758Abstract: 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.Type: GrantFiled: November 25, 2003Date of Patent: January 4, 2011Assignee: Ube Machinery Corporation, Ltd.Inventors: Etsuo Okahara, Toshio Arai, Kazuaki Kobayashi, Takashi Okusako
