Title: Production of blackening resistant hot dip zn-al alloy coated steel sheet
Inventor: HATANO YUJI
IPC: C23C2/06
Filed: 1994-03-31
Abstract: PURPOSE:To suppress generation of clogging in spray nozzles by incorporating an ammonium dihydrogenphosphate into an aq. cobalt nitrate soln. to be sprayed, thereby adjusting its pH in production of a blackening resistant hot dip Zn-Al alloy coated steel sheet. CONSTITUTION:The aq. cobalt nitrate soln. is sprayed to the plating layers while the plating layers right after hot dip coating are in an unsolidified state to prevent blackening after a chromate treatment of the hot dip Zn-Al alloy coated steel sheet. At this time, the ammonium dihydrogenphosphate is incorporated to the aq. cobalt nitrate soln. to be sprayed to adjust the pH to <=4.0. The aq. cobalt soln. is made acidic and the precipitation of cobalt hydroxide does not arise any more. Since, the cobalt hydroxide generated in the aq. soln. is decreased, the clogging in the spray nozzles is suppressed. As a result, the blackening resistant hot dip Zn-Al alloy coated steel sheet free from uneven spraying of the aq. cobalt nitrate soln. is obtd.

Filed: 1986-04-15
Abstract: PURPOSE:To suppress vibration without using a rapid clock and to instantaneously acquire synchronizm by outputting a phase synchronizing signal with F Hz frequency based on an input digital signal sent at the speed of F bits per second. CONSTITUTION:An oscillation circuit 11 oscillates a signal with F(R+M+1) Hz frequency and a frequency dividing circuit 1A divides the signal into 1/(R+M+1+ or -K) frequency and outputs a phase signal. On the other hand, a phase comparator 3 detects a phase difference between an input digital signal and the phase synchronizing signal outputted from the circuit 1A and outputs a phase advance pulse or a phase delay pulse to a control circuit 5 in accordance with the phase difference. Based on the phase advance pulse or the phase delay pulse, the control circuit 5 controls the value of K in the circuit 1A as '0' or '1'. At that time, a protection circuit 1B acts so as to load the circuit 1A when phase variation with a prescribed level is generated in the input digital signal by the prescribed number of times.
