Title: Projection type cathode-ray tube
Inventor: SUGAWARA TAKASHI
IPC: H01J29/89
Filed: 1979-07-18
Abstract: PURPOSE:To raise brightness of a projection type cathode-ray tube by providing a concave mirror of such an oval form that the longitudinal direction coincides with the low- or high-speed scanning direction and forming a vacuum outer case into an oval form matching the shape of the concave mirror. CONSTITUTION:The inside of a vacuum outer case, consisting of the funnel 1 and the face plate 2, is provided with an oval form of the concave mirror 5 so arranged that the longitudinal direction coincides with the low-speed scanning direction, and also the vacuum outer case is formed into such a shape that little clearance is produced between the funnel 1 and the periphery of the concave mirror 5, having an oval section with the same longitudinal and diametrical directions as the concave mirror 5. Thus, when a screen having a screen gain on a three-tube type projection cathode-ray tube is used, brightness can be raised without damaging the uniformity  of color image with regard to the viewing angle as well as the hue by arranging the  cathode ray tube in the diametrical direction of the funnel 1.

Abstract: PURPOSE:To shorten substantially the distance calculation time while properly matching each stroke of an input character to that of a character standard pattern by dividing beforehand the character standard pattern into partial patterns where the variation of the stroke order arises. CONSTITUTION:A CPU3 inputs sequentially vertical information of writing utensils of a character in the midst of writing and handwriting coordinates from a character input device 1 through an interface circuit 2, and detects the number of strokes of the input character based on the information. Then, after a series of preprocessing is terminated, the CPU3 extracts feature points of each strokes and simultaneously calculates distances between the input character and all character standard patterns having the same number of strokes as that of the input character with the aid of a required distance calculation system, referring to the 1st memory (ROM)4. Then the CPU3 selects the minimum value among distances between the input character and all character standard patterns.

Filed: 1981-06-18
Abstract: PURPOSE:To provide high corrosion resistance and heat conductivity to heat exchangers by plating copper beforehand to titanium tubes above a specified thickness and soldering copper or copper alloy fins thereto. CONSTITUTION:In the stage of producing titanium tubes for finned heat exchangers, copper is beforehand plated on the titanium tubes to >=3mu by an ordinary method.
