Title: Squeeze roll with cooling device for manufacturing welded tube
Inventor: HIDAKA TSUNEO
IPC: B21C37/08
Filed: 1994-04-21
Abstract: PURPOSE:To prevent a cooling medium from leaking into a bearing part, even if a sealing member is deteriorated, by making a structure in which a ring- shaped blocking member with a feeding and discharging port of the cooling medium is brought into contact with a roll body through a sealing member thereby blocking the opening of a grooved recessed part in the roll body. CONSTITUTION:A roll assembly A is constituted of a sleeve 6, sleeve cap 7, roller bearing 8 supported with these parts, roll piece 1 supported by a shaft 5, holder 9 and ring shaped blocking member 2. The opening of the grooved recessed part 1a formed in the roll piece 1 is blocked by the ring-shaped blocking member 2 through a sealing member 4-1 to form a passage P for a cooling medium. The ring-shaped blocking member 2 is provided with a feeding port of the cooling medium, discharging port and partition 2a. Since the partition 2a blocks the passage P, the cooling medium enters from the feeding port to the passage P, and goes out from the discharging port, cooling the roll piece 1. The bearing 8 is arranged inside the inner diameter of the roll piece 1 in separation from the sealing part 4-1; and therefore, the cooling medium does not leak.

Title: Method for measuring position of train
Inventor: SEKINE CHOGO
IPC: G01C21/00
Filed: 1994-04-21
Abstract: PURPOSE:To eliminate the necessity for installing a plurality of dead reckoning devices corresponding to a plurality of GPS receivers, by combining a plurality of GPS (global positioning system) receivers with a dead reckoning method, measuring a position of a train and improving a measuring frequency by the GPSs equivalently. CONSTITUTION:A dead reckoning operation is carried out for a forefront position of a train by a dead reckoning operational device 33. The result of at least total length of the train is stored on a locus memory device 34. When either a front GPS 11 or a rear GPS 21 becomes unable to measure a position, a position difference operational device 35 obtains a position difference between the forefront position and a rearmost position of the train based on the locus stored on the memory device 34. A front position operational device 40 or a rear position operational device 50 corrects by the position difference an output of the GPS receiver which is unable to detect the position. If both of the front and rear GPSs 11 and 21 are turned inoperable, a dead reckoning device 30 executes the dead reckoning operation starting from the forefront position immediately before the GPSs are turned inoperable.
