Abstract: Described herein is a method and an apparatus which permit terminal-carrying ends of wire units to be automatically inserted into a connector housing in a reliable manner almost irrespective of the type and size of the terminal elements to be inserted. This is attained by providing a transfer plate which is movable to a position confronting a selected one of a plurality of connector housings set on an assembling table. An assembling head is mounted on the transfer plate movably in vertical directions and also in directions toward and away from the transfer plate. A wire-embracing terminal portion and a wire portion of the wire unit are gripped by means of openable and closable paired terminal gripping pawls and wire gripping pawls which are vertically movably supported on the assembling head. The posture of the terminal element is adjusted by lowering a terminal presser plate which is vertically movably provided between the paired terminal gripping pawls.

Abstract: A phase lock loop for a digital input signal has a phase detector, a loop filter, a digital voltage controlled oscillator (VCO), an initial phase difference calculator, a center frequency difference calculator and an input buffer memory. In an initial training mode prepared in the PLL operation, an optimum initial phase and an optimum center frequency of the VCO to complete a lock-in state is searched for the input signal stored in the buffer memmory. By estimating the initial phase difference and the center frequency difference between the input signal and the VCO output with repetative kick-offs in calculators, optimum values mentioned above are obtained.
