Title: Laser beam cutting nozzle
Inventor: KANEOKA MASARU
IPC: B23K26/14
Filed: 1987-11-13
Abstract: PURPOSE:To promote a laser beam cutting process as assistant gas holds its purity without being hindered by excessive air by selecting the ratio of an inner diameter of a nozzle point to an outer diameter thereof at a specified value. CONSTITUTION:The value of a ratio of an inner diameter d1 of the nozzle 3 to an outer diameter d2 thereof is selected to be >=3. The outer diameter d2 of the nozzle 3 is larger than the inner diameter d1, and at a cutting time, the nozzle 3 is enclosed by a wide surface and faces a work piece 5 through a narrow clearance like a thin sheet. Accordingly, the assistant gas 4 supplied along the laser beam 1 is spouted from the nozzle 3 and ejected at a high speed as the speed of flow is accelerated by a narrow clearance. In this case, since the neighborhood of the cut part of the work 5 is shielded by a narrow clearance in the shape of a thin sheet, the work 5 is fused, vaporized and cut in an instant by the laser beam 1 fitted perfectly to the optical axis. Cutting efficiency is prevented from being deteriorated by dilution, etc., of gas purity based on mixture of the air and the deposit of dross is minimized because the assistant gas is used effectively.

Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To enhance the performance of an optical pickup by making the objective lens receiving surface of an objective fixing structure be in a conical shape or a tapered shape to respectively adjust optical axes of two kinds of objective lenses parallel with respect to the upper part or the lower part of the objective lens fixing structure of a rotary shaft and to reduce an optical axis deviation at the time of changing over two kinds of objective lenses. SOLUTION: An objective lens 2 is mounted on the lens receiving surface 11a of an objective lens fixing structure 11 to be fixed. Since the lens receiving surface 11a is made to be in a tapered shape or a conical shape, the outer circumferential edge of the lens 2 and the surface 11a become to perform a line contact. Consequently, since the structure of this pickup is different from a structure in which the lens receiving surface 11a and the objective lens 2 perform a surface contact, optical axes of the two kinds of the objective lenses can be respectively adjusted parallel with respect to the upper part or the lower part of the objective lens fixing structure 11 or the rotary driving shaft and it is made possible to reduce the optical axis deviation at the time of changing over the objective lenses.
