Abstract: A machine and method for forming an inside corner portion in a one-piece article material (10) where the inside corner portion (28) is produced by the meeting at a corner of first and second adjacent profiles defined by grooves or mem-bers (20, 22). The inside corner por-tion at the corner is formed by ma-chining the article material to form portions of the profiles not includ-ing the entirety of the inside corner portion, and then shearing the arti-cle material in the corner to form the inside corner portion. The ma-chine has first and second cutter as-semblies (102) each having a shear cutter (110). Each shear cutter is mounted for movement along a path between retracted and ex-tended positions such that the path of movement of the cutter of the first assembly meets with the path of movement of the cutter of the second assembly. The article having partial profiles formed therein is mounted with the cutters positioned and seated with the profiles and such that the profiles are aligned along the paths of movement of the cutters. The cut-ters are driven along their responsive paths while seated with their respective profiles between the retracted and extended posi-tions, such that driving the cutters to the extended position shears the material near the corner to form the inside corner portion.

Abstract: A frequency synthesizer, which realizes speed-up of channel switching between channels having separated frequencies,  has an EEPROM  which  stores  the  phase  difference  between  a  first frequency divider  and a  second  frequency divider producing outputs corresponding to the frequencies of the channels to be switched.   A delay circuit delays the output of the second frequency phase divider by an amount corresponding to an amount of the phase difference stored in the EEPROM.   A controller supplies the outputs of the second frequency divider and the delay circuit to a phase detector.  Further, the controller stops a PLL operation and restarts it in synchronism with a leading edge of, preferably, a second period of the output signal of the reference oscillator to which the preset phase difference is given.
