Title: Laser optical axis adjusting device
Inventor: SANO HIDEZO
IPC: B23K26/042
Filed: 1988-09-28
Abstract: PURPOSE:To eliminate the deviation of a laser optical axis so as to facilitate and to shorten a laser treating operation by a method wherein the deviation of a laser optical axis is automatically and on-line controlled to be a minimum. CONSTITUTION:Laser rays 22 emitted from a laser oscillator are directed to a laser treated section through at least two variable reflection mirrors 24. Moreover, a half mirror 2 is provided halfway between them to take a monitor optical axis 28 into a two-dimensional image sensor 20 to detect the deviation of the optical axis from a reference position. And, the reflection mirrors 24 variable in a reflection direction are driven to correct the deviation of the monitor optical axis from the reference position. The deviation quantity of the monitor optical axis 28 from the reference position or the optical axis position displayed on the two-dimensional image sensor 29 is detected in an on-line manner. And, an actuator 42, which drives the reflective mirrors 24 provided on a laser optical axis, is driven so as to make the deviation of the monitor optical axis indicated on the two-dimensional image sensor 20 small. By this setup, the deviation of a laser optical axis from a treated position can be automatically made small.

Title: Anchor bolt joint
Inventor: FUKUI MAKOTO
IPC: E02D5/80
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve the passing ability of slime or a curing material and a void the deviation of a bolt by forming a streak groove in parallel to the shaft center of a joint on the outer peripheral surface of the joint so that a linear shaped-shape may be formed between the outer peripheral surface of a joint and a hole wall. SOLUTION: While water or air is being supplied to a shaft way 21, drilling operation is started by giving turning and striking thereto. The slime produced by drilling is discharged to the side of a pit aperture by way of the peripheral surface between a joint 10 and the hole 40. A linear-shaped streak groove 13 is formed between the joint 10 and the peripheral surface of the hole 40. As a result, the slime passes through this streak groove 13 and is discharged to the side of the pit aperture so that no space may be blocked at the location of the joint 10 during drilling work. After the drilling work is finished, a curing material is injected by way of the shaft way 21. The curing material discharged from a pit 30 is filled up one after another toward the pit aperture side from the inner most part of the hole 40.  Even when the curing material is being filled up, the steak groove 13 still functions as a fill-up passage. It is, therefore, possible to pass the slime of the curing material smoothly and align a post with the center of the hole so that it may be set up.
