Title: Method for reducing generation of air pressure noise at outlet of tunnel by spraying waterdrop
Inventor: MAEDA TATSUO
IPC: E21F17/00
Filed: 1989-12-08
Abstract: PURPOSE:To reduce the generation of noise at the outlet of a tunnel by forming a waterdrop spray section in a tunnel when a train is rushed in a tunnel and reducing the gradient of the front of the wave surface of a pressure wave in the tunnel to a low value. CONSTITUTION:A detecting device 1 to detect the rush of a train 9, a control device 2, and a plurality of nozzles 5 are mounted in a tunnel 8. The rush of the train is detected by the device 1, and waterdrops are sprayed through the nozzles 5 by means of the device 2 right before a pressure wave is propagated to a waterdrop spray section 6 such that the section of the tunnel is covered. By means of the sprayed waterdrops, a part of an input pressure is reduced and the pressure gradient of a pressure wave transmitting the spray section is reduced. After transmission of the pressure wave, spray of waterdrops is stopped. This method reduces the generation of air pressure noise at the outlet of the tunnel and varies a reducing effect through regulation of a spray amount, and is applicable to a new built and an existing tunnel.

Title: Image data communication equipment
Inventor: YAMAMOTO RYOJI
IPC: H04N1/21
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To conduct efficiently facsimile transmission/reception by making file management efficient in a file storage device. SOLUTION: The processing speed is enhanced not by using the entire storage area of a file storage device 623 but by using part of the storage area for a data area R3 to manage files. Furthermore, the data area R3 to store files is not fixed (however, the capacity is constant), and in the case of deleting a file and storing another file, occurrence of fragmentation due to repetition of write and delete is suppressed by deleting the file stored in a storage area 601 and storing the other file to a storage area 602 which is different from the storage area 601 and consecutive to a storage area 603. In the case that the storage area 603 is fully stored, other storage area 605 is used for storing files. Moreover, the file data are deleted virtually on a file management area R2 so that the deleted data are retained to be restored when required.
