Title: Diaphragm type alkali chloride electrolytic bath
Inventor: YOKOTA NORIYUKI
IPC: C25B9/19
Filed: 1979-05-23
Abstract: PURPOSE:To lower the voltage of bath and to prolong the life of diaphragm, by forming the dispersion layer of anode active substance on the anode side of the diaphragm in electrolytic bath and connecting the above dispersion layer with the anode current collector. CONSTITUTION:The diaphragm 2, such as asbestos, etc., is attached on the anode opposite face of the wire net cathode 1 arranged in electrolytic bath. The dispersion layer 3 of the anode active substance, such as MnOx-PdO group, etc., is formed on the anode side of the diaphragm 2. The anode current collector 4, such as Ti, etc., is closely stock on the surface of the layer 3 and current is supplied by conductor. By the above form, distance between electrodes is able to keep at minium. Also, voltage rise between the electrodes is avoided because generated gas on the anode is quickly drawn out from the hole 7 of the collector 4. Moreover, collapse of the diaphragm 2 by the gas and liquid flow at the time of electrolysis, is prevented because the diaphragm 2 is pressure-welded between the cathode 1 and the collector 4.

Abstract: PURPOSE:To control a center frequency in a frequency discrimination characteristic at a high speed by controlling an incident polarized light state to a polarized light preservation fiber. CONSTITUTION:A demodulation signal 201 being an output of a differential amplifier circuit 26 is inputted to a peak detector 27 comprising a half wave rectifier to obtain an electric signal 202 proportional to an amplitude of the demodulation signal 201. A control voltage 203 applied to a polarized light controller 21 is controlled by a controller 28 to which a microprocessor is mounted so as to wave the signal 202 maximum at all times. The mount-climb method (maximum value control method) is adopted for the control, in which a small perturbation is applied to the control voltage 203 to vary the control voltage 203 in a direction in which an electric signal 202 proportional to the amplitude of the demodulation signal 201 is increasing. In this case, the control of the polarized light state of an FSK signal light 102 made incident in the polarized light preservation fiber 22 is equal to the control of a phase difference of two optical components in two fixed axis directions of the polarized light preservation fiber 22.
