CONSTITUTION:A plastic pipe 1 passes through rolls 11, 12, 13 successively while being drawn out of a drum 2 and inserted into a straight pipeline (b) by operating a rope 20. The same is heated by vapor from inside and outside of the pipe while passing from the drum 2 into an inserting hole b1 of the straight pipeline (b) and the softened state is uniformalized inside and outside of the pipe to bend and extend the pipe in the specified direction without difficultly. As the pipe is released from external heating simultaneously with starting to travel into the straight pipeline (b), the same is brought into contact with air to be cooled and hardened. As internal heating by vapor is continued in the straight pipeline (b), cooling and hardening are mainly carried out on an outer layer of the plastic pipe 1. The plastic pipe 1 increases its tensile strength and can withstand traction sufficiently by the arrangement.

Filed: 1986-01-31
Abstract: PURPOSE:To obtain a network control system which stabilizes a required time difference of each passing route, by distributing the flow from a start point to a destination to only routes of less variation of the time required for passage so that the overall cost of a network is minimum. CONSTITUTION:Communication lines through which data can be transferred for transmission and reception of commands, data, etc., only in directions of arrows are set between a control station 1 and terminal stations 2-6. The control station 1 starts measurement; and if the interrupt of time-out occurs, the control station 1 issues such command to terminal stations 2-6 that flow quantities qj from a start point O to a destination D are transmitted to the control station. The control station 1 receives measured results of O-D quantities transmitted from terminal stations and generates a distribution table of the O-D flow on a basis of flow extents of O-D and branch costs hj=DELTA/(qjm-qj) [qjm is a maximum flow extent of a branch (j) and DELTA is a constant] so that an overall cost ZETAqjhj is minimum, and this table is transmitted to each terminal station. The data transfer control is performed on a basis of this O-D distribution table to distribute the flow to only routes of less variation of the time required for passage.

Abstract: PROBLEM TO BE SOLVED: To reduce the abrasion width and the chipping occurrence rate of a flank including a cutting edge boundary abrasion part by equipping the edge of a tip which contains Co and Cr as much as specified weight percentage and has WC as a remainder with a breaker specified in honing quantity and a rake angle. SOLUTION: This is an ultra hard alloy tip composed of Co: 4-8weight%, Cr: 0.1-2weight% and WC as remainder, and the honing quantity of the edge of the tip is decided to be 0.005-0.05mm. When the honing quantity of the edge exceeds 0.05mm, the fusion of a cut material increases, and it is undesirable because chipping and breakage due to the fusion are apt to occur. The rake angle of the edge is decided to be 15 deg.-45 deg.. When the rake angle is less than 15 deg., cutting resistance increases, and it is undesirable because abnormal breakage due to the vibration of the edge is apt to occur.
