Title: Method of machining roots type rotor
Inventor: TAKESHITA HAJIME
IPC: B24B19/14
Filed: 1984-02-28
Abstract: PURPOSE:To finish a rotor having a rugged curved surface on its outer periphery efficiently and with high dimensional accuracy by forming a material to be machined roughly into the shape of a rotor and then grinding it. CONSTITUTION:A workpiece 30 is reciprocated in the axial direction, while the workpiece 30 and a grinding tool 66 are rotated at the same angular speed, and in the opposite directions to, and being engaged with, each other, enabling nearly uniform grinding over the whole outer periphery of the workpiece 30 as well as an efficient grinding. Also, since a shaft part 32 and a shaft 64 are supported, at their both ends, by slides 28 and 52 respectively, the axes of these shaft will not incline, enabling grinding with high accuracy. Therefore, when the workpiece 30 is formed into a rough shape of a rotor by means of cutting, it is not necessary to control the dimensional accuracy so strictly, enabling a rotor to be manufactured at a low cost.

Title: Picture processor
Inventor: MIYASHITA HARUNOBU
IPC: H04N1/405
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To decide an error cumulative value for removing an adverse effect by the error storage of negative difference in a fixed time regardless of the number of picture elements for distributing errors. SOLUTION: A subtractor 5 outputs error between input data and binary data in a binarizing circuit 3. An error data buffer 6 stores error data of the peripheral picture elements, error data is applied with weighting and, then, an error cumulating circuit 7 calculates the sum of error data of the peripheral picture elements. A correcting equipment 8 executes second weighting based on whether the error cumulative value Te is positive or negative and whether the inputted data Pi showing a density has the value to generate dots or not. When input data Pi has the value to generate the dots, that is, when the density of the picture element to be considered is higher than a prescribed value, second weighting is decided so that the absolute value of the negative value of the error cumulative value does not become large.

Title: Cathode-ray tube
Inventor: TOKITA KIYOSHI
IPC: H01J29/86
Filed: 1983-03-09
Abstract: PURPOSE:To reduce curvature in the vertical direction while suppressing substantially a color shift by setting the specific relations among the curvature including a vertical axis, the curvature including a horizontal axis and the curvature including a diagonal axis of the glass panel inner surface. CONSTITUTION:Assuming that the panel curvature of the screen part in the vertical axis direction (1-2v) is (Rp-v), that of the screen part in the diagonal axis direction (1-2D) is (Rp-D) and that of the screen part in the horizontal axis direction (1-2H) is (Rp-H), it is so constituted that the relations of said panel curvature shall be (Rp-v)<(Rp-H)<(Rp-D). Thereby, the mask curvature (Rm-v) of the effective part in the vertical axis direction, which was the dominant factor of the former maskdoming can be brought near to the mask curvatures (Rm-H) and (Rm-D) in the horizontal axis direction or the diagonal axis direction. As for a color picture tube using a shadow mask like this, the amount of mask doming due to thermal expansion of the shadow mask effective part caused by shooting collision of electron beams is substantially reduced and suppressed in comparison with the conventional case.
