Title: Circuit for extracting contour of graphic
Inventor: MOCHIZUKI YOSHIHIRO
IPC: G06T7/60
Filed: 1987-03-18
Abstract: PURPOSE:To output an outline graphic at high speed by using a memory in which the picture element pattern of a contour extraction graphic corresponding to the picture element pattern is stored and a flip flop for holding a bit of continuous information. CONSTITUTION:By using the memory 3 in which the pattern for extracting contour is stored and the flip flop 4, complicated algorithm in software is eliminated, and a large quantity of memory for holding a coordinate value is eliminated, whereby contour extraction is executed in a short time. Namely, continuous information on (n) picture element pattern in an original picture and previous picture element pattern are set to addresses, and an contour graphic pattern stored in the address is outputted, whereby the contour for one direction (one among four directions of +X, -X, +Y and -Y) is extracted. By repeating this action four times, the complete graphic is obtained.

Abstract: PURPOSE:To reduce noise by providing a drive pin with one end inserted in a hole for inserting the drive pin therein through a spherical bearing so as to be reciprocatively movable and with the other end fixedly mounted to the end surface of a piston holder. CONSTITUTION:A frame is formed by a front cover 2 and a cylinder block 4 and has a piston chamber 7. The pot receiver 11 of a universal joint is fixedly fit in the opening 8 of a cylinder 6. There are arranged three holes 12 for inserting drive pins 15 therein on a circle at equal spacing and a spherical bearing 13 is arranged in each hole 8. The heads 14a and 15a of pistons 14 and the drive pins 15, respectively, are fitly arranged, while having plates 16 and 17 fit in a recessed end surface 1c. Since play due to a little dimensional tolerance, if any, is completely absorbed because of the axial movability of the joint portion, little mechanical noise is produced.
