Title: Automatic changeover device of reference frequencies
Inventor: YOSHITOME SEIYUKI
IPC: G11B19/28
Filed: 1978-03-06
Abstract: PURPOSE:To obtain reference frequencies for servo motors matched to video discs by selecting one of the different reference frequency signals and controlling the revolution phase of the motor. CONSTITUTION:The frequency of the chrominance subcarrier when the vertical synchronizing signal is 60 Hz is 3.583125MHz and is higher than the normal refrence frequency 3.58M Hz. As a result, the output voltage of a phase detector 44 which compares the phases of both signals becomes higher than the reference voltage if the case when there are no phase errors is made the reference voltage. And the output signal of this phase detector 44 is inputted to a level detection circuit 48. The first output of the level detection circuit 48 becomes of a high level and therefore if the output signal is applied to the first AND circuit 52, the output of the circuit 52 goes ON. The second output of the level detection circuit 48 is passed through an inversion circuit 49 and becomes of low level and therefore if the output signal is applied to the second AND circuit 53, the output of the circuit 53 goes OFF.

Abstract: PURPOSE:To inspect chip components with high accuracy without being affected by characters on the upper surface of each chip component by generating an inspection range between two electrodes, and identifying faults by means of values measured after the area where light is reflected from the characters is eliminated. CONSTITUTION:A chip component 1 comprising an electrode 2 mounted on a pad 3 is illuminated 4 and a camera 5 outputs a density image signal (a) of the component 5. A binarizing circuit 6 converts the signal (a) into 1 (0) corresponding to the bright (dark) part and outputs a binarized image signal (b). A detection area generating circuit 7 to which the signal (b) is input generates an inspection range between the two electrodes of the component 1, the range being set by a stored inspection range signal (c), and a binarized image signal (d) of the inside of the inspection range from which only binarized images are extracted is output. A character image eliminating circuit 9 to which the signal (d) is input outputs a selected image signal (e) of only the data of 1-label whose length perpendicular to the inter-electrode direction is larger than a preset value. A judging circuit 10 measures the number of 1 when the signal (e) is input thereto, and recognizes the fault of longitudinal deviation when the measured value is larger than a preset criterion.
