Title: Production of nitrogen trifluoride gas
Inventor: MOROKUMA TATSUMA
IPC: C25B1/24
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To efficiently produce nitrogen trifluoride gas by controlling the average current density of a cathode to a specific range to electrolyze. SOLUTION: As nickel used for an anode, one containing Ni portion exceeding about 90 wt.% is used without problems. The composition molar ratio (HF /NH4F) of an electrolyte molten salt is controlled to 1.5-1.9. At the time of producing the nitrogen trifluoride gas by electrolysis using the electrolyte, the average current density of the cathode is controlled to 90-300 mA/cm2. In the case that the average current density is below a lower limit, the potential of the cathode is decreased and the deposition of a Ni ion is insufficient. When the average current density exceeds an upper limit, the generation amt. of gaseous hydrogen is remarkably increased and the danger of explosion due to the mixing of the cathode gas with the anode gas is increased.  Further, the deposited crystal becomes arborescent, the surface area of the cathode is increased to lower the apparent current density and then, the deposition of Ni is decreased. The voltage of the electrolysis is suitably controlled to 5-10 V and the temp. is suitably controlled to about 80-140 deg.C.

Abstract: PROBLEM TO BE SOLVED: To recover control autonomously by controlling a drive means such that all exciting signals fed to the stepping motors of a gas flow rate regulation valve are in-phase during a period for detecting an abnormality on a signal line for transmitting the exciting signal thereby preventing the unintended operation of the valve. SOLUTION: An input circuit 191 receives an input signal 190 and removes noise components therefrom before it is converted into a digital data at an A/D converting section 192. Operation results from a central operating section 193 are outputted, as a control output signal 197, through an output circuit 196. The output signal 197 includes control signals SO for fuel injector, ignition coil and ignition plug and a drive circuit 197 drives each stepping motor according to the driving signal SO and monitors the voltage Sm on the transmission line. When the signal line is abnormal, a controller determines whether a decision was made that the signal line was abnormal in the previous processing and makes a decision that the signal line is abnormal it the waiting time variable is higher than a specified value before starting abnormal time processing.  According to the arrangement, normal control can be started autonomously upon recovery from abnormality.
