  • Patent number: 11788331
    Abstract: One end of first and second arms 30 and 40 are rotatably connected to a first hinge body 10 and a second hinge body 20, respectively. The other end of the first arm is guided by a second guide 25 of the second hinge body and the other end of the second arm is guided by a first guide 15 of the first hinge body. Friction torque is applied on the second hinge body by the friction plate 60. The first guide has a main guide portion 15x and a sub-guide portion 15y that is connected to an end of the main guide portion and draws an arc centered on the first shaft member. When the other end of the second arm is on the sub-guide portion, frictional resistance is not received, so that the second hinge body is automatically rotated by the urging member 70.

  • Patent number: 11767269
    Abstract: To improve the stability of spray application of a monolithic refractory in which a water injector is disposed in a material carrier pipe extending from a material supply device to a distal spray nozzle, and application water is injected from the water injector into a spray material that is being carried through the material carrier pipe, a ratio of a flow volume of an application water carrier gas for carrying the application water to be introduced into the water injector to a flow volume of a spray material carrier gas for carrying the spray material is set to 0.07 to 2, and a compressibility index of the spray material is set to 32% or less. Alternatively, a ratio of a flow volume of an application water carrier gas for carrying the application water to be introduced into the water injector to an application water volume is set to 100 to 1,000.

  • Publication number: 20120191746
    Abstract: A dictionary system available for the use in document search or available for the use in normalization of a term constituting a document. A dictionary system capable of supporting a complex term composed of a plurality of simple terms. A dictionary system includes a storage for storing a simple term dictionary unit containing at least one simple term and a complex term dictionary unit which represents a complex term that contains one of the simple terms constituting the simple term dictionary unit. Each simple term constituting the complex term is referred to through a pointer (unit identifier) to the simple term dictionary unit.

  • Patent number: 6607903
    Abstract: This invention provides novel genes encoding enzymes which decompose difficult-to-decompose thiophene compounds. By using these genes, sulfur atoms can be released from the thiophene compounds in fossil fuel such as petroleum, and the diffusion of sulfur into the environment caused by the combustion of the fossil fuel can be prevented.
