Title: Production of coated electrode
Inventor: HATADA YASUHIKO
IPC: B23K35/40
Filed: 1981-12-09
Abstract: PURPOSE:To obtain a coated electrode which is reduced of times for generation of eccentricity and is markedly improved of paintability by adding liquid N2 to a compounded flux for a coating material and water glass, and kneading these then coating the kneaded flux on a core wire. CONSTITUTION:Liquid N2 is added to the above-described compounded flux and water glass (e.g. sodium silicate No. 1) and these are kneaded and while the mixture is cooled to 5-20 deg.C, the kneaded flux is prepd. In succession, the kneaded flux is mechanically coated on a core wire for low hydrogen stainless steel electrodes, low hydrogen mild steel electrodes, etc., whereby a coated electrode is manufactured. If the temp. of the kneaded flux is <=20 deg.C in this way, no eccentricity is generated even if the standing time after the kneading is 30min, and no flaws on the surface of the covering material occurring in the fluctuations of painting pressure are produced at all.

Title: Synchronizer
Inventor: YOSHIKAWA MIZUO
IPC: G05B19/07
Filed: 1981-12-08
Abstract: PURPOSE:To enhance the synchronization accuracy of a synchronizer for a painting equipment or the like and its safety, by using a fixed frequency divider to divide a clock pulse and using a variable frequency divider to divide an integrated value for a prescribed section of an endless chain and performing control on the basis of an integrated value. CONSTITUTION:A clock pulse sent out from an oscillator 26 is divided by a fixed frequency divider. Integration is effected for a prescribed section of a chain by an integration counter 28 controlled by switches 19, 20 provided in a reciprocator not shown in the drawing. The integrated value C is applied to a variable frequency divider through a divided value automatic setting unit 29 so that the value is divided by the divider. The divided signals are applied to an oscillation counter 31 so that the signals are integrated. When set values N1-N4 for the form, dimensions, etc. of a painted object, which are sent from a digital controller 21, have coincided with counted values, the counter 31 sends out a control signal to open or close a three-way valve 9. Although the constitution is simple, the accuracy of synchronization is enhanced and the safety for prevention of blasting is promoted.
