Title: Color corrector circuit
Inventor: SAKUI MASATO
IPC: H04N9/455
Filed: 1989-02-02
Abstract: PURPOSE:To simplify circuit constitution and to reduce signal degradation by separating a chroma signal into a burst signal and the other signal, varying the gain and phase of the burst signal and varying saturation and hue. CONSTITUTION:Switching circuits 1 and 2 are changed over at the timing of a burst gate pulse inputted from an input terminal 7 and the chroma signal inputted from an input terminal 6 is separated into the color signal and burst signal. This burst signal is inputted to a gain control circuit 4 and the gain is varied by a saturation adjusting variable resistor 8. For the burst signal of which the gain is varied, the phase is varied by a phase circuit 5 and a hue adjusting variable resistor 9. Thus, the burst signal, for which the gain and phase are controlled, is synthesized again with the color signal by changing over a switching circuit 10 and goes to be the chroma signal.

Abstract: PURPOSE:To provide easy applying work, high adhesive force between an urethane layer and a shaft body and good conductivity by applying adhesive agent to a metallic shaft body surface in a spiral form or a vertical stripe form. CONSTITUTION:Urethane series adhesive agent 2 is applied on a metallic shaft body 1 in a spiral form by 2mum in thickness, with applying width of 5mm W, at an applying interval D of 2.5mm, and applying angle A of 45 deg.. After baking the shaft body at 373K for 30 minutes, a metal mold is filled with thermosetting conductive urethane whose liquid temperature is 363K. After the primary cross- linking is carried out at 413K for 90 minutes, it is taken out of the metal mold, the secondary cross-linking is carried out at 383K for 24 hours, and the external profile is ground to a prescribed dimension, thus forming a conductive urethane roller 3. Since a part of the urethane is in direct contact with the metallic shaft body, it is possible to exhibit the conductivity of urethane. Since an ordinary adhesive agent can be used, it is also possible to maintain good workability and prescribed adhesive force when an applied area is secured by 50%.

Abstract: PURPOSE:To replenish a wire for exchanging before molten metal solidifies and to prevent weld defects by interupting the conduction of electricity just prior to the using up of the electrode wire under use, removing the remaining wire, replenishing the wire for exhanging and resuming the welding. CONSTITUTION:When the terminal end of an electrode wire 3 which is let off from a wire reel 9 and is under use disengages from a wire reel 9, immediately the conduction of electricity to the wire 3 is stopped; at the same time,a feed roll 11 is run reverse to pull the wire 3 off.
