Patent number: 9636716Abstract: This vacuum cleaning device is provided with: a vapor chamber in which vapor of a hydrocarbon-based cleaning agent is generated; a condensation chamber; a first heat exchanger in which heat exchange between the vapor and a heating medium is carried out; a cleaning chamber in which a workpiece can be cleaned under vacuum by the condensed cleaning agent that has been generated in the condensation chamber; a compressor that adiabatically compresses and further heats the heating medium that was heated by the first heat exchanger; a second heat exchanger that carries out heat exchange between the heating medium heated by the compressor and the hydrocarbon-based cleaning agent in the vapor chamber; and a vacuum unit that further cools the heating medium that has been cooled by the second heat exchanger by forcing vacuum expansion of the heating medium.Type: GrantFiled: August 12, 2014Date of Patent: May 2, 2017Assignees: IHI CORPORATION, IHI MACHINERY AND FURNACE CO., LTD.Inventors: Atsushi Hirata, Yasuhiro Shigegaki, Tetsuya Hirata, Kazuo Miyoshi, Yoshiyasu Matsuda, Noboru Hiramoto

Patent number: 9605330Abstract: The vacuum heat treatment device includes: a guide plate used to guide a cooling medium supplied by a cooling unit, into a heat-insulating container through one of at least two openings of the heat-insulating container in a state where the two openings of the heat-insulating container are opened; and a movement mechanism used to move the guide plate so that at least part of the guide plate is inserted into a movement area of a cover portion in a state where the two openings of the heat-insulating container are opened and so that the guide plate is retracted from the movement area of the cover portion before the cover portion is moved in order to close the two openings of the heat-insulating container.Type: GrantFiled: June 16, 2014Date of Patent: March 28, 2017Assignees: IHI CORPORATION, IHI MACHINERY AND FURNANCE CO., LTD.Inventors: Kazuhiko Katsumata, Noboru Kiya, Noriaki Nagai, Noboru Hiramoto

Patent number: 5647143Abstract: Herein disclosed are a vacuum-degreasing cleaning method for degreasing a work by cleaning it with a solvent vapor under reduced pressure, and a vacuum-cleaning machine for practicing the method. This method comprises the vapor-cleaning step of cleaning the work under reduced pressure with a vapor of a petroleum solvent, and the drying step of drying the surface of the work under reduced pressure. This cleaning method can clean the work while preventing the deterioration of the working atmosphere and the air pollution and can reduce the initial cost and the running cost for the work cleaning operation. Moreover, the cleaning efficiency can be safely enhanced with neither any thermal influence upon nor any rust upon the work.Type: GrantFiled: January 5, 1996Date of Patent: July 15, 1997Assignee: Japan Hayes Ltd.Inventors: Ken Kubota, Kunihiko Ishikawa, Noboru Hiramoto
