摘要： PROBLEM TO BE SOLVED: To confirm the positional slippage state of a part by the visual conditions of a symbol mark from upper side, by a method wherein the symbol mark printing on a printed wiring board is made in the same size of the contour of an electronic part or smaller than that. SOLUTION: In the visual checking from upper side in the part packaged state, since an IC 1-2 is in the positional slipped state, the symbol mark 1-1 printed below the IC 1-2 is in the visible state. Thus, the IC 1-2 can be judged to be in the positional slippage state. On the contrary, since the IC 2-2 is packaged in the normal position, in the visual checking from upper side in the part packaged state, the symbol mark 2-1 printed below the IC 2-2 is in the invisible state. Thus, the IC 2-2 can be judged to be packaged in the correct position. Through these procedures, any nonconformity part due to the positional slippage of the part can be easily detected.

摘要： PURPOSE:To provide video signals with small blur even at the time of being out of focus. CONSTITUTION:This apparatus is provided with an out-of-focus signal processing circuit 8 and at the time of being out of focus, it is corrected by emphasizing the contour of the video signal while controlling an aperture correcting circuit 4. Therefore, since the contour of the video signal is emphasized even at the time of being out of focus at the video camera, there are effects such as reducing the feeling of blur in the camera output video signal and easily confirming an object or setting an angle of view.

摘要： PURPOSE:To match both of the picture contour of an electronic view finder and the picture contour recorded on a magnetic recording medium by detecting the difference between both picture contours and controlling the focal length of a lens. CONSTITUTION:A picture contour detecting circuit 9 is inputted with a video signal 13 of the picture contour of the electronic view finder 7 and outputs the picture contour signal 14. The presence or absence of the signals 12, 14 is discriminated by a picture contour signal discriminating circuit 10 and the result thereof is inputted as a control signal 15 to a control circuit 3. A lens driving circuit 2 is controlled in the control circuit 3 only when a switch 16 is on the side a. The picture contour of the electronic view finder when the switch 16 is on the side a can be set by previously determining the set value of the discrimination threshold value of the picture contour signal control circuit 10. The driving circuit 2 is put to the initial setting by putting the switch 16 to the side b at the time of recording. The picture contour of the video signal recorded on the magnetic recording medium and the picture contour view finder 7 are then matched or set at a certain ratio.

摘要： PURPOSE:To obtain a line correlation circuit in which the number of pins are reduced by giving a combination function to a IC pin. CONSTITUTION:A video signal inputted from a IC pin 1 is recorded on a magnetic tape through a video AGC circuit 15, a recording/reproducing change-over switch 9 and a LPF16, and passing through a trap circuit constituted with combination a trap and a recording/reproducing discrimination circuit 17 and a trapping block filter 12, and through a recording/reproducing change-over switch 11, an emphasis circuit 19, a frequency modulation circuit 20 and a magnetic head 13. A reproducing signal reproduced by a magnetic head 14 is introduced to a frequency demodulation circuit 21, a de-emphasis circuit 22, the switch 9, and the LPF16 and is outputted through a line correlation circuit 18, the switch 11 and a EE/PB AMP24. Since a IC pin 8 is used also as for a recording/reproducing, only one IC pin is enough for the IC pin that inputs the output signal of the IC pin 8.
