摘要： Improvements in a plastic working process for face-centered cubic metals, and titanium and zirconium having close-packed-hexagonal lattice, which process utilizes a phenomenon that the ductility of these metals is increased at sub-zero temperatures, i.e., temperatures below 0 DEG C. This process includes the steps of (i) imparting plastic flow including at least a uniaxial tensile stress field a metal at a temperature below zero, (ii) subjecting the metal to plastic flow to an extent that the strain of the metal is within the limit of uniform elongation of the metal, and then to plastic flow including at least a uniaxial tensile stress field continuously thereafter, or (iii) using frost as a lubricant for plastic working at temperatures below 0 DEG C according to either one of the foregoing steps.

摘要： A method for jointing two pipes such as an aluminum pipe and a copper pipe by friction welding. The aluminum pipe is inserted into a bore of a ring made of a heat resistant material, the bore having a straight section and a tapered section continuous from the straight section. The copper pipe has a tapered end peripheral surface. The copper pipe is pressed at its tapered end, in a rotating state, against the end of the aluminum pipe so as to expand the latter. As a result, an ironing is effected on the aluminum pipe by the straight section of the bore of the ring, such that the aluminum pipe overlies the straight section of the copper pipe in close contact with the latter. Consequently, the tapered surface of the copper pipe is friction welded to corresponding portion of the aluminum pipe while the latter is being backed up by the tapered section of the bore of the ring.

摘要： PROBLEM TO BE SOLVED: To provide a control system allowing high density operation and less time loss while preventing inter-station stop and a great reduction in speed when a preceding train or an opposite train runs behind schedule to possibly cause influence on a self-train. SOLUTION: After receiving presence information from a train position detector 6 and route information from a route controller 7, a ground management device transmits security information generated in any line position or section, where another train is present to possibly cause influence on a train running at the line position or section, as control information in the section to a train 1. The train 1 finds a timing when a forward unopened position or section is opened, based on the control information, to control its speed to pass through the position at a proper speed for the timing.

摘要： PROBLEM TO BE SOLVED: To provide an optical switch capable of performing highly reliable switching with a small driving force by providing a projection on the substrate side surface of a moving flat optical waveguide. SOLUTION: A separation layer 2 located below cantilever beams 6 and 7 and a connecting member 8 is eliminated by etching, and the surface of substrate 1 is exposed around the cantilever beams 6 and 7 and the connecting member 8. A recess 24 is formed on the full surface of the separation layer 2. In the lower surface of the cantilever beams 6 and 7 and the connecting member 8, a projection is formed in a position corresponding to the recess 24. Friction forces between the cantilever beams 6 and 7 and the connecting member and the substrate are reduced, and adhesion is also suppressed. Thus, even if forces generated by electromagnetic actuators 11a and 11b are small, opticalswitching is performed. Further, since there is no difference in the friction reducing effect even if a gap between the projection formed in the lower surface of the cantilever beams 6 and 7 and the connecting member 8 and the substrate is small, sure optical-switching is performed while changes in the attitudes of the cantilever beams 6 and 7 and the connecting member 8 are maintained small.

摘要： PROBLEM TO BE SOLVED: To provide a means to display a section necessary to carry out the speed regulation at the front side, and a nonopened section visually, to train crew. SOLUTION: On a display device 1, a railway map 2 imitating the railway at the front side and a distance scale 3 are drawn, and a coasting and a power running section 11; a section 12 necessary to regulate the speed at the near side of a speed limit section; a section 13 necessary to regulate the speed for stopping; and a non-opened section 14; are drawn in the various colors or by changing the graduation. In the operation system existing no ground signal, the crew can grasp the section necessary to regulate the speed, and the non- opened section visually. And even in the operation system existing the ground signal, the speed limit information of a far section unable to confirm visually, and a non-opened section information can be grasped.

摘要： PURPOSE:To enhance the acceleration/deceleration performance of a train by minimizing the idling and maximizing the adhesion and to improve the comfortableness by suppressing fluctuation in the driving power. CONSTITUTION:In a drive control system where an AC three-phase motor and an inverter are provided independently for each drive shaft with the inverters being interconnected through a transmission line, the period is shortened 19 in the measurement control of the drive shaft or the torque or speed of one drive shaft is set lower 18 than that of other drive shafts when a possibility of racing is detected 15 based on running state information 23. This method detects an racing in the early stage thereof, reduces the amount of idling and the number of racing shaft.
