The PSGC separates a received optical signal into two orthogonal polarizations and directs the two polarizations to separate waveguides on an integrated circuit. In addition these procedures can be applied as part of any bit loading algorithm to determine the optimal FEC parameters, taking into account the Signal-to-Noise Ratio profile, the FEC coding gain, the constraints of the framer, and any application specific constraints. To control the transfer of this component from auxiliary vessel to storage tank, the device further includes at least one tubular capacitive sonde totally immersed in the fluid mixture, a sonde for measuring the temperature of the mixture, and a sondc for measuring the mixture level in storage tank. The terminal crimping pliers can be extended with a small angle, through a vertical stopping slot combined with two stopping slots with oblique angles, and the terminal crimping pliers can be held closed with a small force. The semiconductor memory device having four pipelining latches for prefetching 4-bit data outputted from at least one bank in response to a start address of the 4-bit data and control signals includes a first data multiplexing unit, a second data multiplexing unit, a third order multiplexing unit and a forth order multiplexing unit.
