Title: Sewing machine
Inventor: KOJIMA MASATOMO
IPC: D05B55/14
Filed: 1993-11-09
Abstract: PURPOSE:To reduce vibration of a sewing machine by reducing a vertical 'exciting force following an up-down movement of a needle bar and also by solving a horizontal exciting force. CONSTITUTION:When an arm shaft 2 rotates. a needle bar 12 vertically reciprocates through a needle bar crank; at the same time, a first balancer 20 and a second balancer 26 rotate at equal velocity and in reverse to the rotation of the arm shaft 2. The needle bar crank 6 as well as both the balancers 20, 26 have their centers of gravity respectively at positions eccentric from the centers of rotation, and are fixed such that their centers of gravity are positioned right above (below) their centers of rotation when the needle bar 12 is at its lowest (top) point. By placing the rotation axes of the needle bar crank 6 as well as both the balancers 20, 26 respectively parallel and on the same plane, the centrifugal force of both the balancers 20, 26 and the inertia force of the needle bar 12 compensate each other, so that the vertical exciting force is reduced and the horizontal exciting force is not generated, and further, no inertia couple is caused around the arm shaft.

IPC: H04N1/409
Filed: 1984-12-26
Abstract: PURPOSE:To enlarge and reduce a binarization picture without producing a moire fringe even if the binarization picture has a periodical structure and to make the filtering of the binarization picture easy by applying the filtering to the number of picture elements and deciding the density level of each block from the picture element of a filtering device. CONSTITUTION:The binarization picture is divided into blocks of appropriate sizes and then the number of black picture elements in every block is counted, and an operation is shifted to filtering. For example, the number of original black picture elements shown in figure (b) is converted to that of conversion black picture elements shown in figure (c) by using a space filter (a). Thus, the density level of every block is decided by the number of the conversion black picture elements and the first density matrix pattern is obtained. After the first density matrix pattern is obtained, the second density matrix pattern sizing in proportion to a multiplying facter of an enlargement or a reduction is obtained in every block and then an enlarged or reduced picture line is obtained in a block order.

Filed: 1985-12-16
Abstract: PURPOSE:To quickly and effectively execute spheroidizing annealing to be executed prior to cold working by executing a hot rolling stage and subsequent heat treatment under specific conditions in the stage of producing a steel wire by hot rolling. CONSTITUTION:A solid round billet of a steel contg., per weight %, 0.15-0.70% C, <0.35% Si, 0.30-1.80% Mn, <0.005% O, and <0.015% S is worked to the steel wire by rough rolling, intermediate rolling and finish rolling at hot. The rolling temp. is so controlled in this case that the finish rolling start temp. is made 650-850 deg.C and that the finish rolling end temp. is made <=950 deg.C. The steel wire is quickly cooled down to a 650-750 deg.C region right after the end of rolling and is coiled to a non-concentrical state. The steel wire is then cooled at a cooling rate of >=0.5 deg.C/sec down to 500 deg.C to form a specified level or above of fine ferrite pearlite structure. The time for the spheroidizing annealing to be executed prior to the subsequent cold forging is thus shortened and the productivity and energy conservation effect are improved.

Abstract: PURPOSE: To effectively utilize a space by arranging vertical materials of a length corresponding to a floor height between vertical beam materials constructed between columns in a standing condition, by arranging diagonal materials between vertical materials and columns to form a truss, and by forming a floor of a large span on downstairs. CONSTITUTION: Vertical materials 3, 3 of a length corresponding to a floor height between vertical beam materials 2, 2 constructed over between columns 1, 1 in a standing condition with a determined space.
