Title: Laser beam processing nozzle
Inventor: OHARA TAKAFUMI
IPC: B23K26/14
Filed: 1984-07-19
Abstract: PURPOSE:To prevent the sticking of the material scattering from a work piece to a laser beam processing nozzle and to permit easy maintenance by providing a means for heating the top end of the nozzle to said nozzle. CONSTITUTION:The blow-off port 10 of the nozzle 9 is heated by a heating source 12 and after the pressure of an assist gas 7 is decreased, a work piece 5 is processed by a laser beam 1. The work piece is then processed while melts 6 scatter. However the port 10 of the nozzle 9 is heated and therefore even if the melts 6 stick to the port 10 of the nozzle, the melts melt and fall immediately and the remaining of the melts 6 sticking to the port 10 is substantially obviated. Long-time processing is thus made possible while approximately the specified spacing is maintained between the top and of the nozzle and the work piece 5.

Abstract: PURPOSE: To facilitate the heating operation to heat a filament to an optimal temperature by automatically controlling the voltage applied to the filament to gradually heat the filament.  
     CONSTITUTION: A current (i) proportional to the voltage difference between the voltage (e 1 ) generated by a voltage generating circuit 9 and the output voltage (e 2 ) of a voltage converting circuit 11 flows through a resistance (R 2 ). When the current (i) is larger than the current (i 1 ) prescribed by a current control circuit 10, a transistor (Tr 1 ) operates to gradually charge a condenser (C 1 ). When the current (i) became smaller than the prescribed current (i 1 ), the transistor (Tr 1 ) becomes off-state so that the voltage of the condenser (C 1 ) is stabilized. A voltage (e 2 ) thus obtained is applied to a filament 1 through a transistor (Tr 2 ) so that the filament 1 is automatically and gradually heated to an optimal temperature.
