Title: Print head
Inventor: ITATSU KISHIHARU
IPC: B41J2/275
Filed: 1990-02-07
Abstract: PURPOSE:To lengthen service life by holding an armature on a leaf spring chip, arranging the fulcrum of the armature on the longitudinal extension of the spring chip, and applying load in the longitudinal direction onto the spring chip. CONSTITUTION:Upon power supply to a coil 11, magnetic attraction takes place and the attracting part 2d of an armature 2 is attracted to a core 9b. Consequently, the armature 2 rotates counterclockwise around a fulcrum 2c, and a print wire 1 fixed at the tip of the armature 2 makes a print through an ink ribbon 14 onto a paper 15 placed on a platen 16. Upon interruption of power supply to the coil 11, the armature 2 is rotated clockwise by the force of a return spring 5 to collide against a stopper rubber 13a where the impact force is absorbed and the armature 2 is stopped. In a series of print operations, the contact parts of the armature 2 and a hold spring 3 move integrally without rubbing with each other thus substantially eliminating abrasion.

IPC: B32B5/00
Filed: 1987-02-10
Abstract: PURPOSE:To facilitate the fixing of the position of a carbon fiber two and at the same time cancel the untwisting torque and contrive to enhance the high straightness by a structure wherein reinforcing fiber filament bundles, which constitute the cross section, are arranged so as to form a radially symmetrical multilayer structure. CONSTITUTION:Reinforcing fiber filament bundles forming a central layer A and a peripheral layer B are impregnated with matrix resin solution and, after excess resin being squeezed out of the bundles, passed through a delivery guide so as to form the central layer and the peripheral layer and, after that, passed through a heating die for forming. Further, the resultant bundles are drawn through a two-step gripping system or caterpillar system drawing mechanism so as to be hardened and shaped simultaneously. When thermoplastic resin is employed as the matrix resin, the reinforcing fiber bundles forming the central layer and the peripheral layer are stratified by the delivery guide, and at the same time impregnated with molten resin and passed through the heating die so as to be shaped simultaneously with the resin impregnation in order to be drawn through the drawing device. Further, in order to obtain a high straightness after grinding, the preferable strain is 0.6mm or less at the middle of a span of 600mm in the stage or a stock rod.

Title: Tufting machine
Inventor: SAKAWA KATSUAKI
IPC: D05C15/18
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a tufting machine capable of preventing the fluctuation of the tension of a yarn on the yarn-feeding side of a yarn tension-adjusting means for adjusting the tension of the yarn passed through the hole of a needle and thereby capable of preventing troubles such as the fluctuation of the height of cut yarns and the separation of the yarn from the needle. SOLUTION: This tufting machine is provided with a yarn tension-adjusting device for adjusting the tension of the yarn S passed through the hole of a needle and with a yarn-metering device 40 which is formed on the spool side of the yarn tension- adjusting device and which looses the yarn S between yarn guides 33 and 34 in order to eliminate a tension applied to the yarn S on the spool side of the yarn tension- adjusting device. The yarn-metering device 40 is swung with a swinging shaft 51 synchronously with the vertical movements of a needle rod, a needle and a yarn take-up lever. During the downward movement of the yarn take-up lever, a yarn-fixing member 42 fixes the yarn S, and a yarn-hauling member 43 hauls the yarn S on the yarn-feeding side to form the loosed route C between the yarn guides 33 and 34. The yarn-fixing member 42 subsequently releases the yarn S.  Although the yarn S is consumed during the upward movement of the yarn take-up lever, the yarn S is loosed. Thereby, the yarn S fed into the yarn tension-adjusting device is placed in a tension- free state.
