Title: Comb-line filter
Inventor: FUJIWARA NAOHISA
IPC: H04N5/21
Filed: 1984-08-31
Abstract: PURPOSE:To reduce noises without adversely affecting a vertical resolution degree by operating a switch as a comb-line filter only when no high frequency component of an input signal lines. CONSTITUTION:When the level of a subtractor output 5 comes to threshold levels S1 and S2 or more, it is judged to be no correlation, and a correlation detection circuit 13 outputs a correlation detection signal 14. The threshold levels S1 and S2 of the correlation detection circuit 13 are controlled by a detection signal 7 outputted from a level detection circuit 6. When the level of an input luminance signal is minimal, said signal is so changed to come to the levels S1' and S2', and is set so that the presence or absence of the correlation can be discriminated irrespective of the magnitude of the level of the input luminance signal. When there is no correlation, the correlation detection circuit 13 causes an analog switch 15 to be turned off and prevents the deterioration of a vertical resolution degree with an input luminance signal 1 as an output signal 12. Where the correlation is found, the switch 15 is turned on to act it as a comb-line filter and noises are reduced.

Abstract: PURPOSE:To prevent the off-track due to the deformation of thermal expansion, by fastening tightly a housing of a spindle to a different member which is fitted and adhered from outside to a projected part of a base and setting the coefficient of thermal expansion of said member approximately equal to that of the housing and smaller than that of the base respectively. CONSTITUTION:A sleeve member 16 is formed with a material having a coefficient of thermal expansion equal to that of a housing 13 of a spindle and smaller than that of a base 1. The member 16 is fitted and adhered from outside to a circular wall part 18 at the fringe of a through hole 17 for the housing 13 of the base 1. A flange part 14 of the housing 13 is fastened and fixed to the member 16 by means of a bolt 15. Thus the thermal deformation which causes an inclination of the spindle 14 can be suppressed although the housing 13, the member 16 and the base 1 are expanded by the heat generated while a storage device is working since the coefficient of thermal expansion of the part 14 is equal to that of the member 16. Therefore the occurrence of the off-track is prevented.
