Abstract: ABSTRACT    There is disclosed a new and improved method for making a stamping master for video disk repli-cation wherein a film of material which is revers-ibly convertible between two stable states, one having a high electrical conductivity and the other having a low electrical conductivity, is de-posited on a substrate while in one of the states.  The material is then imaged with informa-tion in coded form by converting selected areas of the film to the other state in a predetermined pattern corresponding to the coded information.   The conversion can be accomplished by light, elec-tromagnetic energy or heat.    At this stage, an intermediate subassembly, composed of the imaged film on the substrate, is formed which can be read for accuracy by detecting the state of the selectively converted areas with respect to the rest of the film.  Corrections can be made by converting the state of selected areas of the film as required.    A metal, such as nickel, is then electro-plated onto the areas of the film which are in the high conductivity state.  The plating is continued until the nickel spans the areas of the film on which it did not directly plate.  In this way a continuous backing layer which is integral with the plated nickel is formed.    The nickel is then separated from the imaged material to provide a first stamping master which is used to form a second stamping master of oppo-site polarity to the first, preferably by a simi-lar plating onto the first master.  The second stamping master is used directly for video disk replication.

Abstract: ABSTRACT A color video signal processing device for a color image pickup apparatus which allows the satura-tion of a particular primary color to be enhanced with a good S/N ratio and without affecting the other colors.  The image pickup apparatus generates a multiplex color signal which is made up of a low frequency range signal containing all the three primary color signal components and a high frequency range carrier signal modulated with first and second primary color signal components, which are predetermined by the colors of a color stripe filter installed in the image pickup apparatus, and in turn these signals and processed and transformed generally to three primary color video signals and a luminance signal. The low frequency range and high frequency range signals are separated from the color multiplex signal and the separated high frequency range signal is subjected to envelope detection.  The signal level of at least one of the separated low frequency range signal and the envelope-detected  signal is adjusted such that a third primary color signal component absent in the high frequency range signal is introduced into a difference signal produced by subtraction of the envelope-detected signal and the low frequency range signal.

The propeller (12) has a series of three lobes or blades (40-42) which are concentrically arranged at 120° apart positions so that the minimum diameter of the blades are at the ends of a hub (43) from which the blades integrally extend.  The blades extend over the length of the hub over about a 360° of rotary motion.  The blades (40-42) are symmetrical from their ends to the mid points on the vanes from either direction top or bottom so that the propeller is reversible without loss of efficiency.  The  leading edge (50) of each of the blades regresses from a point from the start of the blade progression tangent to the outside of the hub at each end so that this falling away of the angle of attack of the blade causes any debris striking the blade, such as rags or string to fall away outwardly of the blade hub so that it does not ball up or otherwise adhere to the hub area.
