Title: High current carbon dioxide arc welding wire
Inventor: TOKINORI KENJI
IPC: B23K35/30
Filed: 1994-03-22
Abstract: PURPOSE:To improve arc stability and droplet migratability and to decrease spatters by specifying the compsn. of a high-current CO2 arc welding wire. CONSTITUTION:The canpsn. of the high-current CO2 arc welding wire consists, by weight%, of <=0.10% C, 0.5 to 1.2% Si, 1.2 to 2.0% Mn, 0.15 to 0.30% Ti, 0.0020 to 0.0050% Se, <=0.0010% Ca and the balance Fe with inevitable impurities. The decrease in the amt. of the spatters by addition of the Ti is significant and the content thereof is required to be <=0.15% in order to adequately stabilize droplet migration. The amt. of the slag increases and the toughness of weld metal degrades if the content exceeds 0.30%. The Se decreases the surface tension of droplets and decreases the amt. of the spatters by fining of the droplets. The Ca forms a Ca oxide in the weld metal and, therefore, the arc length is made unstable.

Abstract: PURPOSE:To reduce nuisance to the neighborhood due to alarming sound for preventing the forgetting of returning a winker of motorcycle and the like by providing a delay means which permits an alarm to produce the alarming sound with a delay to the on-operation of a flasher switch. CONSTITUTION:When a flasher switch 4 is connected to either left or right contact during vehicle travelling, current flows through a main switch 2 to be switched by a flasher relay and flash either left or right flasher lamp 5. A portion of current after passing through the switch 4 passes through a diode 24 or 25 and resistor 26 to charge a capacitor C29. When the terminal voltage of C29 reaches a predetermined voltage or more, a transistor 21 is turned on through a Zener diode 23 to operate an audio-pilot 27 for producing buzzer. When the vehicle stops at a crossing and a clutch switch 6 or neutral switch 7 is turned on under such condition, C29 is discharged in a cancel circuit 10 to stop the buzzer.
