Abstract: A unitarily formed diverter valve assembly for use in liquid chromatography.  The valve assembly comprises a plurality of inlet and outlet ports, diverter valve systems, chambers, and a tortuous network of passageways all of which are arranged to accommodate the flow of fluids in a liquid chromatography system. The valve assembly is configured so as to direct the flow of fluid coming from an inlet port through the valve body where it can then be reversibly directed into or out of a chromatography column.  On returning form the column, the fluid reenters the valve assembly where it is directed to an outlet port in order to exit the system.  The valve assembly can also be configured so as to bypass the column altogether.  Since the entire valve assembly is machined out of a single block of material having smooth liquid passageways, and since all flow compartments are shared and fully flushed when a flow-through valve is opened, dead-legs are virtually eliminated from the system.

Abstract: An AFC (Automatic Frequency Control) device and a method of controlling reception frequency in a dual-mode terminal. When a dual-mode terminal uses one or two AFC circuits, time required for acquiring tracking synchronization in a PLL circuit for a frequency can be reduced using a test augmentation frequency being an integer multiple of a tracking synchronization acquiring residual frequency of a PLL circuit for another frequency to which the first frequency transits for reliable synchronization acquisition. Errors with respect to an output dynamic range caused by use of two AFCs are reduced and thus the demodulation performance of a receiver is ensured by varying quantization bits of an A/D clock based on the dynamic range of residual errors in a frequency area. The demodulation performance can also be ensured by operating an ACPE circuit for an AFC circuit having many residual frequency errors. In this method, the frequency characteristics of the dual-mode terminal are stabilized and the stability of a demodulator is increased due to a frequency offset. As a result, the stable demodulator performance is ensured.
