Title: Video signal processing unit
Inventor: YAMAMOTO YOSHIYUKI
IPC: H04N9/83
Filed: 1988-04-19
Abstract: PURPOSE:To erase interference from a luminance signal to a color burst signal when separated luminance signal and chrominance signal are mixed again and to prevent the band degradation of the luminance signal during a period to be displayed on a screen by band-limiting the frequency band of the separated luminance signal only during a color burst signal period. CONSTITUTION:The output of a mono-multiplier circuit 11 is set to be wider than the color burst signal period by the degree of 0.5 to 1.0musec before and after the period and the output of a low-pass filter 8 is operated so as to be conducted to the output of a signal switch 7 only during the period. Accordingly, the frequency band of the luminance signal is band-limited only during the color burst signal period and the interference from the luminance signal to the color burst signal is widely suppressed. Thus, with simple constitution, the band degradation of the luminance signal is completely erased during the period to be displayed on the screen and further, the interference from the luminance signal to the color burst signal can be almost erased.

Filed: 1980-07-14
Abstract: PURPOSE:To protect a slide table of a feed device from damage caused by collision or the like, by connecting the slide table with a feed mechanism through a connecting member which is easily broken. CONSTITUTION:When a threaded shaft 4 rotated by a motor, an upper slide 11 is moved in the axial direction of the shaft 4 together with a nut 5 and a lower slide 6. When a trouble occurs in a drive system or the like in the machine tool, the feed  mechanism 10 becomes uncontrollable and the upper slide 11 crashes against a  frame or the like. At that instant, a breakable connecting part 12c pro-vided next to a notch 15 of the connecting member 12 is broken, whereby the shock of the  crash is prevented from being transmitted to the feed mechanism 10 as such. Accordingly, it is possible to protect feed mechanism 10 and the slide table 11 from damages.
