Title: Separation of palladium by extraction
Inventor: ICHIISHI TOMOSHI
IPC: C22B11/00
Filed: 1987-05-18
Abstract: PURPOSE:To inexpensively and efficiently extract a Pd in an organic solvent and to isolate by bringing a hydrochloric acidic aq. soln. which contains a Pt or Rh and Pd into contact with the organic solvent containing dihexylsulfide, and extracting the organic solvent with the water. CONSTITUTION:The hydrochloric acidic aq. soln. which contains the Pt and/or Rh, and the Pd is brought into contact with the organic solvent containing the hexylsulfide. As the above-mentioned organic solvent, the dihexylsulfide itself or its solution further diluted with non-polar solvent such as cyclohexanone, etc. Hence, the Pd and a small quantity of the Pt and/or Rh are transferred into the organic solvent. Subsequently, the above-mentioned organic solvent is reversibly extracted with the water. Thus, the Pt and/or Rh are selectively transferred into the water, hence the Pd is separated in the above organic solvent.

Moreover, a read address of the memory 10 is controlled at an address control section 42 controlled by an address stop circuit 43 and a data of the convergence adjustment point set for the blanking period is interpolated by using the same data as that at an extrapolation point and the result is outputted. Thus, the capacity of the correction memory is saved and the interference between extrapolation points is reduced to realize the convergence correction with high accuracy.

Filed: 1977-10-14
Abstract: PURPOSE:To ensure reduction of the channel selection time (down to 1 sec. from conventional 8 sec.) while keeping the satisfactory accuracy, by switching the sweep velocity of the tuning voltage sweep circuit at the channel selecting time. CONSTITUTION:RS-type FF16 is set every time the data value of counter 13 becomes zero and then reset every time the 17 units of the pulse supplied from all- zero detecting circuit 20 are supplied to up-down counter 14' and the data value becomes 35, 52... from 18. Thus, rectangular waves (II) and (III) whose widths change largely every cycle of counter 13 are obtained at the Q-output to be applied to electronic tuner 1. Then tuner 1 receives a high-speed sweep coaxial operation and reaches the prescribed channel (No.N) to generate the end signal of count 7. As a result, the tuning voltage is changed slowly (IV-X), and the fixed channel selection is completed with the same velocity and accuracy as conventional.
