Title: Demodulation system for check signal in television identification control signal
Inventor: FUKINUKI NORIHIKO
IPC: H04N5/44
Filed: 1993-12-27
Abstract: PURPOSE:To identify a check signal in good condition by adding an input almost over a check period using one period of a check signal as a pitch and setting up a DC component and a check frequency component to a value less than a certain threshold and a value more than a certain threshold respectively. CONSTITUTION:In order to extract and check a 2.04MHz component, a receiving signal is inputted by closing a gate 1 over a check period B25 to B27. A shift register 2 consists of seven stages and its final stage is added to an input by an adder 3. Before closing the gate 1, the contents of the adder 3 are reset by a reset switch 4. When an output from the adder 3 is inputted to the register 2 and successively added on positions separated in each seven cycles, the same signal is circulated in each check period after the end of the check period. In the case of extracting the 2.04MHz component from the signal circulated in the circulation type register, a band pass type digital filter 5 can be applied. Consequently the 2.04MHz component larger than a certain threshold is checked.

Abstract: PURPOSE:To automatically load a film which is wound around a spool and never unwound to spread with its spring-back force by reverse winding by providing the spool with an outer peripheral surface which contacts a guide roller eccentric with the center of the rotary shaft. CONSTITUTION:The support shaft 17a of the spool 17 is positioned eccentrically with the center shaft 17b of the spool 17. Consequently, when the spool 17 rotates on the support shaft 17a, the spool 17 is energized against a guide roller 21 by a spring 20 through a planetary lever 14 for the spool. Here, when the film rotates the spool 17 by larger than a specific angle in the opposite direction from the film winding direction with its spring-back force, an energizing means needs to be charged according to the quantity of eccentricity of the spool 17. Here, the quantity of eccentricity, energizing force, etc., are determined exceeding the spring-back force to suppress the rotation of the spool 17 to <=1 rotation. Consequently, the simple structure prevents the film from being unwound to spread.
