Title: Tunnel ventilation controller
Inventor: OHASHI HIROYUKI
IPC: E21F1/00
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a tunnel ventilation controller with surrounding environment taken into consideration, by preventing the outflow, to the outside of a tunnel, of contaminants generated from a travelling vehicle in the tunnel. SOLUTION: An exhaust shaft 12 is provided so as to lead to the outside out of the midpoint in a tunnel. In a concentrated exhaust-type tunnel 11 exhausting contaminants generated from a vehicle out of a tunnel by an exhauster 13 placed in the exhaust shaft 12, the volume of air of the exhaust shaft 13 is increased or a contaminant removal device 5 is operated if the measurement of a contamination-concentration detector 1 exceeds an allowable range. Therefore, the concentration of contaminants exhausted to the outside of the tunnel can be suppressed, thus it is possible to have no effect on surrounding environment.

Title: Radial magnet and its production
Inventor: SATO MORIHIRO
IPC: H01F7/02
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To suppress breaking or cracking by machining the inside of a radial anisotropic sintered magnet at first with an inner grindstone and then machining it from the outer circumferential side with an outer grindstone.
