Publication number: 20240147296Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference to which an interfered-with wireless communicator to be protected is subjected by interfering wireless communicators. A repeater disposed between the interfering wireless communicator and a controller includes a processor and a memory storing a program executed by the processor. The processor acquires registration information including a position and a transmission power for each interfering wireless communicator, and estimates, for each interfering wireless communicator, a terminal range in which there is a likelihood that a terminal wireless communicator communicating with the interfering wireless communicator is present based on the position and the transmission power. The processor transmits a registration application including the terminal range to the control device.Type: ApplicationFiled: June 8, 2021Publication date: May 2, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Junichi IWATANI, Yasuhiko INOUE, Yusuke ASAI, Yasushi TAKATORI

Patent number: 7588831Abstract: An oil-resistant sheet material which has low resistance to gas permeation and excellent oil resistance and is suitable especially for use as a packaging material for foods containing an edible oil. The oil-resistant sheet material is obtained by forming at least one coating layer from a material comprising a hydrophobized starch and a crosslinking agent on at least one side of a base in an amount of 0.5 to 20 g/m2. By incorporating a fatty acid and/or polyvinyl alcohol into this coating layer, oil resistance is improved. A coating layer comprising a fatty acid as the main component or a coating layer comprising polyvinyl alcohol as the main component may be formed on that coating layer. Thus, a coating layer composed of at least two layers may be formed.Type: GrantFiled: August 10, 2004Date of Patent: September 15, 2009Assignee: Tokushu Paper Mfg. Co.
