Abstract: PURPOSE:To operate a camera only in a range where vertical smear compensation is sufficiently performed and video signals of the high quality are obtained, by providing the titled device with a means to display an alarm when a vertical smear component exceeds a prescribed value. CONSTITUTION:A video signal read out from a solid-state image pickup element 1 is supplied to a vertical smear compensating circuit 9. An adder/substractor 3 adds or subtracts a compensated signal from the smear compensating circuit 9 to/from the video signal and impresses the calculated results to an output terminal 11 and a view finder 10 through a video processing circuit 4. The smear compensating circuit 9 is provided with an AD converter 6, a digital memory 7, a DA converter 8, and a level detecting circuit 12. The level detecting circuit 12 supervises the vertical smear component, and when the component exceeds the prescribed value, actuates an alarm display device 13 in the view finder 10. Consequently, the camera can be operated only in the range where the smear is sufficiently compensated.

Abstract: PURPOSE:To form a welding metal, where cracks and hardening do not generate in the welding part, without preheating and postheating for welding of cast iron, by adding a specific quantity of Nb, Zr, Ti, and so on to the welding rod of the Fe base including Mn, Cr and Cu. CONSTITUTION:The material of a composition consisting of 5-36% Mn+2Ni, 0- 4% Cu, 12% Nb+Zn+2Ti, 0.5-8.0% Cr, 0.05-2.1% C, and the balance Fe is used as the welding rod for structural welding of cast iron or supplementary welding of cast defective products. Since lots of C in the welding metal is fixed as a carbide together with strong granular carbide forming elements such as Cr, Nb, Zr, and Ti, and carbon quantity in the welding metal is reduced considerably. Since lots of Mn and Cu coexist in the welding metal, the melting point of the welding metal is lowered considerably, and the white pig iron layer of the welding metal becomes thin considerably. Thus, the welding metal can be prevented from being hardened and cracked even if preheating and postheating are omitted, and welding of pig iron is performed effectively.
