Title: Work carrying device of sewing machine
Inventor: NAKAMURA MASAO
IPC: D05C9/04
Filed: 1993-12-28
Abstract: PURPOSE:To quickly perform a pattern sewing by judging whether at least a seam is within perfect area or pitch stitch area, and correcting the feeding direction of a work. CONSTITUTION:In a post type sewing machine M, a rotating table 5 on a mount base 1 is rotated through a cylindrical body 4 by a rotating motor 7. An X- moving base 10 on the rotating base 5 is moved in the direction X by an X- motor 13. Further, a Y-moving base 11 on the X-moving base 10 is moved in the direction Y by a Y-motor 16. The rotating motor 7 is controlled in such a manner that the positive feeding direction orthogonal to the needle thread insert hole of a needle is conformed to the seam forming direction. The perfect stitch seam angle formed by the seam farming direction and the positive feeding direction is calculated, it is judged whether the seam is within the pitch stitch area or not, and the rotating motor 7 is rotated by a prescribed angle to set the seam forming direction of a work in the calculated angle direction.

Title: Apparatus and method for cleaning printing head
Inventor: ENZ RICHARD T
IPC: B41J2/165
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To remove dried deposits without using mechanical contact at all which could abrade or damage orifices by using a cleaning fluid having a low surface tension for dissolving or flushing a material from the orifices. SOLUTION: A solenoid-operated air vent valve 9 permits a cleaning liquid to flow into a liquid drop generator 10 through a filter 11. When vacuum is supplied to the liquid drop generator 10 through an opened outlet valve 14, the cleaning fluid flushes away ink residues from an interior of the liquid drop generator 10. When the outlet valve 14 is closed, the cleaning fluid flows through an orifice 12. The cleaning fluid then rinses ink residues from a charge plate face and a catcher 13. When the catcher 13 is turned to a vacuum state, the cleaning fluid is returned together with the ink residues to a fluid device. An outer face of the generator 10, the charge plate face and catcher 13 are cleaned in this manner.
