Title: Pilot signal fm modulating system in catv system
Inventor: WARATANI YOICHI
IPC: H04N5/00
Filed: 1985-04-09
Abstract: PURPOSE:To precisely detect a level of a pilot signal P by FM modulating a pilot signal of a pilot AGC in a CATV system in at least a wider band than a frequency changing band L of a filter. CONSTITUTION:A pilot signal P of a pilot AGC in a CATV system is FM modulated so as to deviate a frequency in at least a wider band than a frequency changing band L of a filter. As mentioned above, since the pilot signal is FM modulated and the frequency deviating band is made wider than the frequency changing band of a band pass filter, it is difficult to reverse a temperature change or an aged deterioration of the band pass filter. Accordingly, the level of the pilot signal is precisely detected and stably and effectively, the AGC can be applied.

Abstract: PURPOSE:To enable the reduction in the charging time to the power source, by arranging at least one spring wheel into a series of transport trains for rotary transmission in linkage with the operation of an external operation member. CONSTITUTION:As an external operation member 1 is turned in the direction of the arrow by a finger, a spring 11 is deformed with transmission wheels 5-9. When the resilience of the spring 11 overcomes the load of staying in place under a magnetic force, a friction or the like of a rotor 15, a spring wheel 10 is turned with the unwinding of the spring 11 and the rotation thereof is transmitted to the rotor 15. The transmission wheels 5-9 have an acceleration wheel train from the member 1 so that the spring 11 can be deformed more with a less movement of the member 1 to enable the setting of the spring 11 to be wound up faster than being unwound. Thus, the rotor 15 can be turned continuously depending on the force of the spring 11 though with no rotation of the member 1 when the member 1 is turned back to the original position by a finger thereby enabling the constant generation of power.

Abstract: PURPOSE:To check the lowering of the printing quality with a higher reliability by a method wherein an ink is supplied from an ink fountain and a tubulet provided with numerous through holes axially extending is moved onto a recording medium to form a dot thereon. CONSTITUTION:When a coil 5 of an ink transfer mechanism is energized electrically, an armature 3 is attracted on to a yoke 4 to move a tubulet 1 to a printing medium 10 through a collor 2 engaged with the armature 3.
