Title: Mold press apparatus
Inventor: MINAMI TAKEHIRO
IPC: B29C45/80
Filed: 1988-09-22
Abstract: PURPOSE:To prevent beforehand breakage of a molding mold and driving mechanism during the period of the abnormal control of a driving motor by detecting shift opposed to energizing force of the energizing member of an ejector bar, and providing a detector for outputting the detection signal. CONSTITUTION:As a shifting plate 24 is descended by a driving motor and driving mechanism (ball screw) 25, and a ejector bar 39 exerts force to an ejector pin 36, the ejector pin 36 acts to thrust upwards a resin molded matter (work) 34 in order to release out the molded matter 34 from a lower mold 33. Furthermore, as the shifting plate 24 is descended so as to make the ejector bar 39 to exert force to the lower mold 33, on the contrary, the ejector bar 39 moves downwards so as to contract an energizing member 40 in opposition to the energizing force of the energizing member (coil spring) 40, and thus alleviates the impact force thereof. And, a detector (microswitch) 42 detects the shift of the ejector bar 39, and the detected signal is outputted thereafter.

Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a new communication system that reconfigurs an image with high definition without aliasing from received information even when a document is processed as a binary image and sent and the document is magnified or reduced. SOLUTION: A contour point string is extracted by tracing a contour from a binary image according to the 8 connection rule and both end points of a straight line and corner points at a right angle included in the contour point string are extracted as junction points. Then a partial contour point string partitioned by the junction points is approximated by a quadratic partial polynomial and both end points of a circular-arc and a straight line are extracted newly as junction points based on the approximation result. Furthermore, in the case that the circular-arc or the straight line is continuons and even when the junction points are eliminated to keep data quality, the junction points are eliminated. The junction points left not eliminated are approximated as a function in the order of a circular-arc, a straight line and a free curve and then the coding is conducted.
