Patent number: 8844290Abstract: A steam engine and an electric motor are arranged, which respectively drives an air compressor. The compressed air from the air compressor is supplied to a compressed air using device through a common air tank. The steam is supplied to the steam engine through a steam supply path, and the steam used in the steam engine is supplied to a steam using device through a steam exhaust path. The steam pressure is monitored by a pressure sensor arranged in a steam header ahead of the steam exhaust path. The air pressure is monitored by a pressure sensor arranged in an air tank. A steam supply valve is controlled based on the steam pressure and the air pressure, and the electric motor is controlled based on the air pressure. The steam engine is preferentially driven over the electric motor by shifting the target value of the air pressure.Type: GrantFiled: April 14, 2008Date of Patent: September 30, 2014Assignee: Miura Co., Ltd.Inventors: Yuji Yoshinari, Yasuo Ochi, Hideo Furukawa, Yasukuni Tanaka, Yusuke Okamoto, Kazutaka Baba

Patent number: 8721849Abstract: A substantially ring-shaped seat section (8) protrudes from an inner circumference wall in a through hole (4) of a container attaching section (6) made of a metal. On an outer circumference of an electrode shaft (3) held in the through hole (4) through an insulator (5) made of a synthetic resin, locking protrusions (13, 14), which have a diameter larger than a hole diameter of the seat section (8), are provided at a distance from the seat section (8), on at least inner side or outer side of the seat section (8) in a shaft direction of the electrode shaft (3). Thus, for instance, when the inside of the metal container (2) is at a high temperature, the insulator (5) is destroyed and the electrode shaft (3) is to jump out from the container attaching section (6) to the outside or the inside of the metal container (2), the locking protrusions (13, 14) lock the seat section (8) and prevent the electrode shaft (3) from jumping out.Type: GrantFiled: December 27, 2005Date of Patent: May 13, 2014Assignee: Miura Co., Ltd.Inventors: Hideo Furukawa, Tomohisa Takeda

Patent number: 7628067Abstract: An insulating coating formed of engineering plastic with high-heat resistance, high-pressure resistance, and chemical resistance is formed on a surface of a water-level detecting electrode part of an electrode rod for detecting water-level attached to penetrate a metal container communicating with a boiler and including an external power supply connecting terminal part projecting outside the container and the water-level detecting electrode part projecting inside the container. One side of a power supply is connected to the external power supply connecting terminal part, and another side of the power supply is connected to the container for energization. An electrostatic capacity between the water-level detecting electrode and the container is measured by using the insulating coating on the surface of the water-level detecting electrode part as a dielectric. The water-level of water in contact with the water-level detecting electrode part in the container can be detected from the electrostatic capacity.Type: GrantFiled: February 16, 2007Date of Patent: December 8, 2009Assignee: Miura Col, LtdInventors: Yuji Yoshinari, Hideo Furukawa, Osamu Tanaka
