Title: Eyelet button holing method using sewing machine
Inventor: IIMURA IKURO
IPC: D05B3/06
Filed: 1993-04-09
Abstract: PURPOSE:To make the length of a button hole equal to that in the case of double bar tacking by adding both straight stitches for a distance equal to the width of an annular part in an eyelet with the on-off operation of a button hole pressor switch, at the time of eyelet button holing using a sewing machine. CONSTITUTION:At the time of eyelet button holing using a sewing machine, a worked cloth 5 is clamped between a buttom hole pressor 1 and a feed dog 4 on the throad plate 3 side, and fed forward and backward. When a projection 6 is moved for a fixed distance, the pressor 1 operates a detecting lever 8 of a position detecting switch 7. The position detecting lever 7 includes two button hole pressing switches 11, 12 selectively pressed by the base end part 10. In this case, as straight stitch parts are connected to semi-annular part for forming an eyelet, at the time of sewing both staight parts, after the second switch 12 is turned on, a distance equal to the width of the annular part in the eyelet is added to both straight stitches. Thus, the length of a button hole is made equal to that in the case of double bar tacking.

Filed: 1989-03-31
Abstract: PURPOSE:To prevent production of color jitter and to improve color blurring and sharpness of color by adding proper amount of a shoot waveform to a color signal to make leading and trailing characteristic steep and suppressing the high frequency component. CONSTITUTION:A contour correction signal output circuit 16 generates a contour correction signal h' making the ratio of shoot quantity different so that the shoot quantity at the first half of the trailing and the latter half of the leading of a contour correction signal (h) is increased and the shoot quantity at the latter half of the trailing and the first half of the leading of a contour correction signal (h) is decreased in response to the waveform level of an output signal (b) of a delay circuit 2. The signals h' and (b) are added by an adder 14 to form a signal (i) with pre-shooting and over-shooting. Then signals (d), (e) of maximum and minimum level output circuits 4, 5 and the signal (i) are fed to a shoot waveform elimination circuit 8, where pre-shoot and over-shoot are eliminated and from which a signal with steep leading and trailing characteristic is outputted. Thus, production of color jitter is prevented and the picture quality is improved.
