Filed: 1993-04-20
Abstract: PURPOSE:To beautifully sew the end of a sewn article by providing a means not executing empty feed data on and after a time when a signal is inputted from fabric end detection procedure at a time of empty feed and skipping sewing pattern data up to a next actually sewing part. CONSTITUTION:The body 18a and a label 18b are set to a definite position and an automatic sewing machine is started to successively move an alpha1 actually sewing part up to an A-point to execute actual sewing. When the actually sewing part comes to the A-point, only a pressure is moved without performing actual sewing to execute empty feed in the direction of a B-point. At a point of time when the actually sewing part reaches the B-point, a fabric end is detected by a fabric end sensor to be confirmed by an input/output device. The empty feed from the B-point to a C-point is skipped by the input signal of the fabric end sensor to execute the actual sewing from the C-point to the A-point and the actual sewing from the C-point to a D-point. Therefore, the empty feed of an actual input pattern becomes the distance beta of actual sewing with respect to a distance alpha2 and is competed at the B-point. By this constitution, sewing free from irregularity can be performed.

Title: Electron gun for cathode-ray tube
Inventor: YANAI KEIJI
IPC: H01J29/48
Filed: 1987-04-15
Abstract: PURPOSE:To smooth change of potential distribution along a Z-axis and aim at widening a range by inserting at least two auxialiary electrodes between main electrodes, making the length of the auxiliary electrodes in the passing direction of the electron stream shorter than that of both main electrodes and shorter than the diameter of the hole in the main electrodes. CONSTITUTION:The axial potential of auxiliary electrodes 11, 12 around the center is an intermediate potential as the potentials of an adjacent focusing electrode 5 and an anode 6 interfere. As the length of the auxiliary electrodes 11, 12 becomes short, the potential of the auxiliary electrode 11 along a central axis decreases, and the potential of the auxiliary electrode 12 along the central axis increases. Potential distribution 13 becomes smoother by this, and a lens diameter becomes larger, thereby spherical aberration is reduced.
