Patent number: 5873313Abstract: In a vacuum housing (1), an inner duct (17) is disposed. Quadrupole magnets (superconducting coils) (4) is placed around the inner duct (17) is excited by a DC power supply (10). Quadrupole magnets (4) are cooled by liquid helium contained in a helium housing and outer tubes (2, 3) and is brought into a superconducting state. Pulverized coal X is ejected together with air Y from a header (11) through piping (12) and a valve (13) to a baffle plate (14). Pulverized coal is made to fall into the inner duct (3). Paramagnetic materials such as ash are attracted by magnetic force to the tube and are then collected by a collection tube (26). Combustible diamagnetic materials are collected by a combustible collecting tube (18) extending in the central axis. Intermediate materials are collected by an intermediate collection tube (23) and are put back to the head (11) through a bypass tube (25). There are no mechanical parts in the inner duct (3). Consequently, rotation loss and eddy-current heating are prevented.Type: GrantFiled: April 25, 1997Date of Patent: February 23, 1999Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masaharu Minami, Hiroyuki Katayama, Takuya Kimura

Patent number: 5145753Abstract: A noble solid electrolyte fuel cell includes a generating layer (5), an interconnector layer (9), and a support layer (10) disposed between the generating and interconnector layers. The interconnector layer comprises a fuel electrode (6), an interconnector material (7) and an oxygen electrode (8). The support layer (10) forms a fuel passage and an oxidizer passage, and supporting rods (15, 102) for gas sealing are disposed at both ends of the support layer. A sealing film (110) is cemented to the contact surfaces of the supporting rods (15, 102) between the generating layer and the interconnector layer, and this sealing film becomes soft or half melted during the operation of the fuel cell. This construction provides improved cell performances due to better sealing of gases even under large temperature differences. The use of finer particles near the surface of the solid electrolyte only is also disclosed.Type: GrantFiled: September 6, 1990Date of Patent: September 8, 1992Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Mitsuhiro Irino, Tetsuo Gora, Masaharu Minami, Hitoshi Miyamoto, Masao Sumi, Nobuyoshi Tomita, Kiyoshi Watanabe, Kazumi Ogura, Masanori Nishiura, Masayuki Funatsu, Kazuhiro Yoshimoto, Koichi Takenobu, Tokuji Satake
