摘要： A shaft manufacturing apparatus includes a first drawing die having a cylindrical first cavity defined therein which is open at both ends thereof and a second drawing die having a cylindrical second cavity defined therein which is open at one end thereof. The angle formed between a first tapered part of the first drawing die and the axis of the first cavity is greater than the angle formed between a second tapered part of the second drawing die and the axis of the second cavity.

摘要： A color separation optical system includes a set of prisms which separate incident light into components having different wavelengths. Image pickup devices may be exposed to the separated light components. An arrangement prevents or reduces the influence of a temperature variation upon color separation characteristics. The color separation optical system may be manufactured in a new way.

摘要： In a moving body tracking apparatus having a moving body recognition circuit and TV camera, the moving body recognition circuit includes: a contour signal generator for producing a first contour signal indicative of contour of an image defined by at least one field, a second contour signal subsequent to the first contour signal, and a third contour signal subsequent to the second contour signal, a first and a second memory for temporarily storing, respectively the first and the second contour signals; contour line width increasing circuit responsive to the first and second memory for increasing the width of contour line represented by output signals of the first and second memory; and comparator responsive to the third contour signal and output signal from the contour line width increasing circuit for producing an output signal when a contour line represented by the third contour signal is out of phase with a contour line represented by the output signal from the contour line width increasing circuit. As a result, moving body except for undesired small movement can be satisfactorily extracted.
