Title: Grinding method and grinding device
Inventor: SHINADA KUNINORI
IPC: B24B13/06
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To simplify the control of a grinding tool and prolong the service life of the grinding tool by removing a projection part by applying a peripheral fringe part of the grinding tool to the projection part without bringing a bottom face part of the grinding tool which is rotating into contact with a face to be processed when the projection part of the processing face exists on a scheduled travel path of the grinding tool. SOLUTION: When a grinding tool 41 approaches a projection part 8a1 , the grinding tool 14 is tilted and a peripheral fringe part 14b is applied on the projection part 8a1 to remove the projection part 8a1 . Peripheral speed of the grinding tool 14 becomes the maximum speed in the peripheral fringe part and is reduced as the grinding tool 14 approaches the center of rotation. The same thing can be applied to grinding amount. Consequently, the projection part 8a1 removal time is shortened when compared with the case where grinding is done by applying a bottom face part 14a to the projection part 8a1 merely. Moreover, since it is possible to change grinding amount arbitrarily without changing the number of revolutions of the grinding tool 14, it is unnecessary to perform the complicated control concerning the number of revolutions of the grinding tool 14 during the grinding work.  Moreover, since a use section of the grinding tool 14 is changed, the whole grinding tool 14 is worn without eccentricity.

Title: Screw for excavator for pile installation by inner excavation
Inventor: SHIBAYAMA YOICHI
IPC: E21B3/00
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To easily insert a screw into a hollow bore by a method wherein rolling rollers, each slightly projecting beyond the outer diameter of the screw, are provided at a spiral blade at the end of the screw, and the rolling rollers are brought into contact with the interior of the hollow bore. SOLUTION: A screw 10 is equipped at its center shaft 11 with a spiral blade 12 and is enabled to be inserted into a hollow bore of a pile 13. The outer diameter of the spiral blade 12 is smaller than the inner diameter of the hollow bore of the pile 13. The spiral blades 12 in plural numbers are used, being connected together, depending on the length of the pile 13. A plurality of rolling rollers 14, each projecting slightly beyond the outer diameter of the screw 10, are provided at the spiral blade 12 positioned at one end of the screw 10. On inserting the screw 10 into the hollow bore of the pile 13, the rolling rollers 14 are brought into contact with the interior of the hollow bore of the pile 13 and thereby friction resistance between the internal wall of the hollow bore of the pile 13 and the screw 10 can be reduced sharply, enabling smooth insertion to be possible.
