  • LNG power plant
    Patent number: 7603840
    Abstract: An LNG (liquefied natural gas) power plant has a heating/cooling device. The heating/cooling device is controlled by a command generated by a temperature control device. The temperature control device receives a heating value and a temperature of the fuel gas. The heating value of the fuel gas introduced to a gas turbine power generation unit from an LNG vaporization facility is detected by a heating value detector. The temperature of the fuel gas is detected by a temperature detector. A target temperature calculator installed in the temperature control device calculates a target temperature based on the heating value. A command generator installed in the temperature control device generates the command by comparing the target temperature and the fuel temperature.

  • Indication label to be adhered to rubber tire and material of label
    Patent number: 5358772
    Abstract: A material for an indication label to be adhered to a rubber tire. The label is designed to be disposed on an unvulcanized raw rubber tire and then fixed to the finished tire by vulcanization using heat and pressure. The indication label having a label base material with a heat-resistant plastic film and an abrasive surface coating layer formed on the upper surface of the plastic film. The abrasive surface being composed of a hardened resin and filler. An indication defined by an ink layer is disposed on the abrasive surface. A rubber adhesive laminated on the lower surface of the plastic film adheres the label to the tire. The label is constructed by forming the ink layer on the exterior side of the abrasive surface coating layer. The abrasive surface having a profile and roughness for preserving the quality of the indication.
