Title: Laser cutting method and laser cutting torch
Inventor: UENO HITOSHI
IPC: B23K26/064
Filed: 1993-06-25
Abstract: PURPOSE:To improve cutting speed by injecting an outer assist gas along an inner assist gas and swirling both gasses for injection. CONSTITUTION:When a material to be cut is irradiated with a laser beam 1 and simultaneously oxygen is supplied to the passage 24 of an inner assist gas, a swirling gas flow f1 is formed by a flow straightening member 26. When oxygen is supplied to the passage 22 of an outer assist gas, a swirling gas flow f2 is formed by a flow straightening member 28. The swirling gas flow f1 prevents the lowering of oxygen purity caused by the atmospheric air taken in and also by combustion gasses and slag mixed in. By the ambient protection through the swirling gas flow f2, the directivity of the swirling flow f1 is protected from being interfered by an external air flow. Consequently, a new assist gas with a high purity is always supplied to the cross-section.

IPC: G10L19/00
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To prevent grating noise like operation noise caused immediately before completing reproduction from being reproduced. SOLUTION: When a recording button 102 is pushed, a memory control means 9 compresses speech data inputted from a speech input part 5 by DSP 6 before recording in a speech data storage part 8a of a memory 8. At this time, a control table control means 11 records a start address of a record-starting point of the speech data in a control table storage part 8b. When a stop switch 103 is pushed, a memory control means 9 stops recording the speech data. At this time, the control table control means 11 records a record address preceding a few hundred seconds before ending the record of the speech data in the control table storage part 8b as an end address. Next, when reproduction button 101 is pressed, the memory control means 9 reads the speech data from the speech data storage part 8a and reproduces them, but stops reading the speech data at an end address. Consequently, the operation noise, etc., immediately before the end of recording are not reproduced from a speech output part 10.
