Title: Oxygen starvation safety device
Inventor: SUGANO TADAO
IPC: F23N5/10
Filed: 1984-01-24
Abstract: PURPOSE:To make it possible to obtain a positive and safe oxygen starvation operation by making the pitch between burner ports corresponding to the thermocouple provided in the vicinity of a ceramic burner, increased as compared with the pitch of other parts. CONSTITUTION:The ceramic burner 11 is provided with a plurality of burner ports 12 (thickness t1 and distance l1 between burner ports) and burner ports 15. The thermocouple B14, is located in the vicinities of burner ports (thickness t2 and distance l2 between burner ports) and keeps the dimensional relationship t2<t1<l8<l1. Since the thickness t2 of the burner port 14 is smaller than that of other port, the injection speed of a gaseous mixture is slightly larger. Since the distance l2 between the burner ports is set smaller than the distance between other ports, flames interfere with each other and flames easily extened upwardly when the O2 concentration decreases. Accordingly, when the thermocouple B14 receives more quantity of heat from the flame 17 and the concentration of O2 reaches a concentration at which the flame 16 is overlapped on the flame 17, the flame abruptly extends and the electromotive force increases. When the electromotive force reaches a preset electromotive force pressure, a safety valve operates a gas circuit to cut off the gas circuit. Consequently, prior to the incomplete combustion, it is made possible to positively stop the combustion.

Title: Direct current arc welding machine
Inventor: KOBAYASHI MAKOTO
IPC: B23K9/06
Filed: 1979-02-02
Abstract: PURPOSE: To reduce spatter and sustain arc stably by series-inserting the welding reactor connected with an impedance at both ends of the control winding to a welding current output circuit.  
     CONSTITUTION: When a consumable electrode 4 shortecircuits to base metal 5 in the shortcircuit transfer region of DC arc welding using consumable electrode, the shortcircuit current shows sharp rise owing to the action of a reactor 6 and resistance (impedance) 7, thereby easing the generation of arc. When it comes to the large current region of the shortcircuit current, the inductance of the reactor 6 increases and therefore the peak value of the shortcircuit current does not become large. Further, the current value flowing in control winding 6-b may be increased or decreased depending upon the number of turns of the control winding 6-b and the resistance value of the resistance 7 connected in series to the winding 6-b, by which the magnetic effect that the winding 6-b gives upon the main winding 6-a, i.e., the rising sharpness and peak value of the shortcircuit current waveform may be selected as desired.

Abstract: PURPOSE:To shorten the pattern recognizing time by providing a spiral scan processing means which scans spirally a dictionary pattern to a pattern to be checked, a scanning start point position correcting means, and a pattern deciding means which decides the coincidence/discordance between the pattern to be checked and the dictionary pattern. CONSTITUTION:A prepared dictionary pattern is spirally scanned to a pattern to be checked and segmented out of the picture data inputted via a spiral scan processing means A. Then a scanning start point position correcting means B corrects the spiral scanning start point of the means A to a position nearest to the pattern to be checked when the scanning position of the dictionary pattern reaches the position nearest to the pattern to be checked. A pattern deciding means C decides the coincidence or moncoincidence between the pattern to be checked and the dictionary pattern based on the number of discrepant bits between both patterns. As a result, the matching scanning frequency is reduced.
