Inventor: OGAWA YASUHEI
IPC: E02D3/12
Filed: 1981-07-03
Abstract: PURPOSE:To perform a continuous implanting of grout without a break, by a method wherein a protection tube is fabricated from a plural number of split- tubes so that it sheathes a flexible grout implanting tube at the inside, and the protection tube is coupled to a preceding existing protection tube. CONSTITUTION:An implanting pipe C, sheathed with a protection tube A, is inserted in a ground togetherwith an excavating tube B by a boring equipment D. Two split-tubes 2 and 2' are then assembled so that they sheath the flexible grout implanting tube C emerging from the upper end of the upper-most protection tube A to form a protection tube, and lower threaded end parts 1 of the two split-tubes screw an upper half part of an internal thread part of a coupler E whose lower half part screws the upper end of the protection tube located second to the uppermost protection tube. The protection tube is further inserted in a ground by the boring equipment D, and the same work is repeated to insert the flexible implanting tube to a given depth to implant grout.

Title: Aging method for slowly cooled blast furnace slag
Inventor: FUKUDA TOMIYA
IPC: C21B3/04
Filed: 1980-07-28
Abstract: PURPOSE: To reduce the period of time required for an aging settletment by a method wherein a slowly cooled blast furnace slag is heaped outdoors and gases in the heap of slag are positively discharged to the outside of the heap.  
     CONSTITUTION: The slowly cooled blast furnace slag is heaped outdoors, and several hollow pipes 5 are driven downward into the heap of the slag from the top surface of the base. By the presence of the pipes 5, the gases in the heap 1 are positively discharged. By such a simple method, the period of time required for the aging treatment can be largely reduced. In addition, it is more advantageous to use an exhaust pipe fitted with a ventilator or a blower or an exhaust pipe connected with an exhaust equipment in place of the hollow pipes 5.

Title: Method and apparatus for inserting coil
Inventor: TSUGAWA TAKAYUKI
IPC: H02K15/06
Filed: 1988-04-26
Abstract: PURPOSE:To prevent a coil from suffering damage, by moving a movable blade holding a coil simultaneously with a stripper at the time of insertion of said coil in such manner that said blade is caused to protrude by a given length from the end face of a stator core and then to go back. CONSTITUTION:A movable blade 1 arranged annularly in the manner of corresponding to the internal teeth of a stator core 40 is caused to hold a coil 30 and is inserted into said internal teeth of the stator core 40. From about the time when said coil 30 is driven by a stripper 2 and comes into contact with the inlet end face of said stator core 40, said movable blade 1 is moved simultaneously with the stripper 2. Then, when the movable blade 1 protrudes by a given length from the opposite end face 41 of the stator core 40, the blade 1 is caused to go back to the position for separating from the coil 30 while the stripper 2 is advanced. Thus, because a friction force between the blade 1 and stripper 2 decreases sharply, the coil 30 is prevented from suffering damage, and because the perimeter of said coil becomes the shortest, the waste of wire rods is also eliminated.
