Title: Pll video detection circuit
Inventor: TAKEMURA HIROKI
IPC: H04N5/455
Filed: 1987-05-20
Abstract: PURPOSE:To prevent the disturbance onto an audio and a picture signal without unrequired decrease in the lock range of a PLL by providing a trap circuit eliminating the undesired component to the post-stage of a phase detection circuit. CONSTITUTION:The trap circuit 7 eliminating the undesired component is provided to the post stage of a phase detection circuit. That is, since the fH component in the undesired component included in the output of the phase detection circuit 4 is attenuated sufficiently by the trap circuit 7 in the PLL lock state, no fH component is included in the output of the low pass filter. Thus, the disturbance onto the video detection output is not caused due to the fluctuation of the voltage controlled oscillator VCO 3 caused by the fH component to prevent production of stereo buzz. In the case of applying the titled circuit to an American audio multiple television receiver, the distortion factor at stereo demodulation is improved by selecting the center frequency of the trap circuit 7 as 2fH to prevent the production of buzz noise.

Filed: 1984-06-14
Abstract: PURPOSE:To obtain functions of high positioning accuracy with small size and high thrust by suitably varying the height between a rotor shaft of a movable element with a piezoelectric unit and the supporting surface in response to the moving mode of the element. CONSTITUTION:A linear pulse motor has a movable element 101, a stator 103 and a roller 106, generates an adhesive force between the element 101 and the stator 103 by a magnetic force based on the bias magnetic flux of a permanent magnet 51 to that the force becomes larger as the gap 105 is smaller.
