Title: Multi-head embroidery sewing machine
Inventor: SHIBATA EIJI
IPC: D05C9/06
Filed: 1992-06-30
Abstract: PURPOSE:To allow a sewing machine to simultaneously embroider the same pattern on a curved material and a flat one without changing embroidery data in particular by rotating a curved cloth extension frame in synchronization with the travel of a movable frame in the direction of Y by controlling the rate of rotation of the curved cloth extension frame and the rate of movement of the movable frame in order that the correspondence of them is one-to-one. CONSTITUTION:One ends 20a, 22a of wires 20, 22 are held to a curved cloth extension frame 15 for a curved material, and the other ends 20b, 22b to a movable frame 11. The one end 20b of the wire 20 and that 22b of the wire 22 are extended in parallel in the direction of Y to equalize the radius of curvature of turns of wires 20, 22 and that of the frame 15. Thus, when the movable frame 11 travels in the direction of Y, the wires 20, 22 are extended in that direction interlocking with the travel, and the rate of rotation of the frame 15 and the rate of travel of a flat cloth extension frame 12 are equal. In this way, embroidering of the same pattern simultaneously on a curved material and a flat one is possible.

Title: Josephson circuit
Inventor: NAKANISHI TAKUJI
IPC: G11C11/44
Filed: 1983-09-19
Abstract: PURPOSE:To obtain simpler construction of a circuit and to attain higher speed of its operation by installing a Josephson switch and a current loop, thereby obtaining a corresponding signal A' and a complementary signal - A' from an address signal A without using a signal for setting. CONSTITUTION:When the signal CS is inputted as ''1'' to a control wire C2, and to a control wire C of a switch G3 as ''1'', by inputting an address signal A, to a control wire C1 of a Josephson switch G1 for setting in the initial state, and inputting a start signal CS as ''1'' to a control current path S1, a Josephson contact element J of G1 and G3 is switched to the voltage-ON condition. As a result, the routes of bias currents of G1 and G3 change. In this case, bias currents of the control wires C1 and C2 of G2 have reverse polarity to each other. Therefore, the element J of G2 does not switch to the voltage-ON condition. Consequently, an address signal - A' is obtained as ''0'' at an output wire M1. An address signal A' is obtained as ''1'' at an output wire M2 by the flowing of a bias current to the control wire C1 of G4.

Title: Cable winding traverse gear
Inventor: TAKEDA TAKAYUKI
IPC: B65H54/28
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To improve workability by using driving force of a driving device for rotating operation of a traverse shaft without manual operation in case of adjusting the position of a guide part of a traverse gear for guiding a cable onto a winding drum. SOLUTION: Rotatory-driving force of a hydraulic motor 3 is diverged by a gear device 4 to drive a winding drum 5 and a traverse gear 1 for normal cable winding. At the time of stopping rotation of the winding drum 5 to adjust the position of a guide base 13, the hydraulic motor 3 is rotatory-driven after cutting off a clutch 6 between the hydraulic motor 3 and winding drum 5. This rotation is therefore transmitted only to the traverse gear 1, so that a traverse shaft 11 is rotated, and the position of the guide base 13 can be adjusted. Since driving force is thus used for position adjustment of the guide base 13, workability is improved.
