Patent number: 6516630Abstract: When the start button is pushed after the door of the supply chamber is closed, carbon dioxide gas is ejected from the nozzle placed at the upper part of the horn. The carbon dioxide gas is converted to powdered dry ice by adiabatic expansion in the horn, and the dry ice falls on fresh food or other items to be cooled in a box or plastic bag placed under the horn. In order to obtain a desired amount of dry ice constantly, the ambient temperature, the pressure of the carbon dioxide gas, the interval time since the last ejection are counted in determining the carbon dioxide ejecting time length.Type: GrantFiled: July 16, 2001Date of Patent: February 11, 2003Assignee: Kakubayashi Shoji Co., Ltd.Inventor: Michio Ishida

Patent number: 5586140Abstract: A plasma melting furnace has a melting chamber having an anode torch and a cathode torch made of graphite and having a electric conductor disposed on the bottom thereof. When the furnace is operated, the anode torch, having an inflow of electrons, which forms an unstable plasma arc is contacted with the electric conductor and is not used, while the cathode torch, having an outflow of electrons, which forms a stable plasma arc, is utilized for heating, whereby the furnace can be stably and continuously operated. Thus, since the cathode torch which is used is not heated so much and the anode torch, which is liable to be heated to a great degree, is not used, the electrode consumption rate can be greatly reduced.Type: GrantFiled: August 3, 1995Date of Patent: December 17, 1996Assignee: Hitachi Zosen CorporationInventors: Michio Ishida, Tsutomu Kuwahara, Hideo Sato, Yoshitoshi Sekiguchi, Kunio Sasaki, Shiro Sakata, Hiroshi Kosaka, Toshio Hirai
