  • Publication number: 20240147296
    Abstract: 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.

  • Publication number: 20240147441
    Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference given to an interfered device to be protected by a large number of interfering devices. The system provides a control device disposed in a public network with a resource application based on a message issued regarding use of a radio resource by an interfering device disposed in a carrier network. A response based on a message issued by the control device with respect to the resource application is provided to the interfering device that has issued the resource application. A resource table including information in which availability of frequency in carrier network is estimated is updated on the basis of the resource application and the response. The information in which the availability is estimated and included in the resource table is reflected in the resource application.

  • Patent number: 7588831
    Abstract: 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.

  • Patent number: 6663960
    Abstract: Fluorescent particles strongly fluorescing upon irradiation with ultraviolet rays, as well as a process for producing the same, are provided. A water-insoluble fluorescent dyestuff and/or pigment fluorescing upon irradiation with ultraviolet rays and a powdery material including starch, cellulose, other polysaccharides and sugars are mixed and granulated. The surface of granules of the powdery material may be coated with the fluorescent dyestuff and/or pigment. In granulation or coating, a resin having reactive groups reacting with the hydroxyl groups of the powdery material is used in combination, whereby particles excellent in water resistance can be obtained. Further, the interaction between an anionic binder contained in the granules and a cationic material contained in the coating layer or between a cationic binder contained in the granules and an anionic material contained in the coating layer can be utilized to confer water resistance on the particles.
