Title: Video clamping circuit
Inventor: TARUSATO AKIYUKI
IPC: H04N7/20
Filed: 1980-10-15
Abstract: PURPOSE: To suppress the variation of a pedestal level by attaching a noise detecting circuit and controlling so as to weaken the clamping efficiently of a switching circuit for pedestal clamping by an output from the noise detecting circuit at the time of low S/N.  
     CONSTITUTION: A clamp pulse is applied from a logic circuit 9 to the 1st gate of a dual gate FET to switch a switching circuit 10 for pedestal clamping. When a noise signal included in a video signal is in a low level, S/N is kept high and the voltage applied from a noise detecting circuit 2 to the 2nd gate of the dual gate FET is approximately 0V, so that FET controlled by the clamp pulse operates with high clamping efficiency to keep the pedestal level at a subscribed value. Since the voltage applied from the noise detecting circuit 12 to the 2nd gate of FET increases negatively at the time of low S/N, the clamping efficiency is weakened gradually  and the dual gate FEt stops its operation, preventing noise on a picture from being generated.

Title: Production of fe-co-si based alloy sheet having high permeability
Inventor: TSUKAGOSHI NOBUHIRO
IPC: H01F1/14
Filed: 1980-10-17
Abstract: PURPOSE:To produce the titled alloy sheet excellent in uniaxial anisotropy by a method wherein an Fe-Co-Si alloy sheet prepared by a super quenching method is heat treated in an oxidizing gas atmosphere to impart a uniaxial anisotropy to the sheet, and then the sheet is heat treated in a non-oxidizing atmosphere at a temperature of not higher than the melting point of the alloy. CONSTITUTION:An alloy base material consisting of 10-20wt% of Co, 8-16wt% of Si and the balance of Fe is melted, and the molten alloy material is jetted from a nozzle onto twin rollers rotating at a high speed or the like to form a belt-shaped sheet through quenching and rolling. The alloy sheet thus obtained is then heat treated in an oxidizing gas atmosphere such as air or O2 at a pressure of 0.2-0.3 Torr to cause the rolled surfaces of the sheet to become uniaxially anisotropic. The heat-treated alloy sheet is then heated to a temperature of not higher than the melting point of the alloy in a non-oxidizing atmosphere such as H2 or Ar gas. As a result, an Fe-Co-Si based high-permeability alloy sheet containing Fe as a major component and having soft magnetic properties with excellent uniaxial anisotropy is obtined.
