Abstract: PURPOSE:To prevent the influence of bubbles and to stabilize developing accuracy by holding the liquid surface of the part where the monitor light of a developing soln. passes by the pressure of the gas flowing out of one end of a lens barrel. CONSTITUTION:The developing soln. is sprayed on a rotating master disk 1. The master disk 1 is irradiated with the laser beam from a laser beam generator 4 through a transparent glass plate 9 at the other end of the lens barrel 8, the inside of the lens barrel 8 and one end of the lens barrel 8. The screen nitrogen fed into the lens barrel 8 from a gas inflow port 8a is discharged from one end of this lens barrel 8. The liquid surface of the part of the developing soln. where the laser light passes is pressed by the pressure of this gas and, therefore, the influence of the bubbles in this part is eliminated. As a result, the detection signal of a primary photodetector 6 obtd. from a photoresist layer 1b which is the body to be developed of the master disk 1 is stable and good without spike-like noises and improves the development accuracy of the photoresist layer 1b of the master disk 1.

Abstract: PURPOSE: To detect the end face of a bar-like pipe, to flare the same, to confirm the worked surface at the same time, and to perform uniform flaring by providing an air sensor to a cylinder rod coupled with a vertically moving cylinder and a pipe expanding punch.  
     CONSTITUTION: When a bar-like pipe 2 is inserted into fins 1, and a pipe expanding punch 3 is lowered, a dog 29 presses a limit switch 31, thereby stopping the descending of the punch 3. At the same time, a limit switch 34 operates to drive a motor 13, which in turn rotates a screw bar 15, then a bracket 33 fixed to a cylinder 18 descends and an air sensor 32 arrives at the end face 2a of the bar- like pipe, and stops the running of the motor 13. At the same time, a limit switch 27 operates to move the piston 19 of the cylinder 18 downward until a dog 26 arrives at a limit switch 28, then the descending of the piston 19 is stopped. During this time, the pipe 2 is flared by the punch 20 coupled to the piston 19, and the air sensor 20a of the punch 20 confirms the flaring.

Title: Transistor driving circuit of dc arc welding machine
Inventor: MIZUNO MASANORI
IPC: B23K9/073
Filed: 1980-12-10
Abstract: PURPOSE: To prevent the breakdown of an output controlling transistor (TR) as an output control element of a welding machine by connecting a capacitor in parallel with a limiting resistance suppressing the base current to said output controlling TR.  
     CONSTITUTION: When welding is started, an on command is outputted from an output control circuit 7, and a driving transistor (TR)6 switches on. As a result, the base current flows through a capacitor 21 as well only at the moment of the switching on of the TR6 at the same instant when the base current flows from a DC electric power source 4 for driving to the base of an output controlling transistor 2 through a limiting resistance 5. As a result, the TR2 is sufficiently satd. and assumes a switched on state, thereby assuming the state of deriving an output through a main DC power source 1, the TR2 and a DC reactor 3. During welding, the TR2 repeats on and off, but the TR2 is held satd. with the capacitor 21 at all times while it is on, and this makes it possible to prevent its breakdown.
