Title: Process for bending plastic window frame
Inventor: KANG HUN-GU
IPC: E06B3/22
Filed: 1983-12-23
Granted: 1986-07-23
Abstract: Nails(11)(11') are fixed with a constant distance along the drawn line of a bending window on the plate(12). Synthetic resin peices(1) (2) are made flexible in the heated silicon oil at 120 140 C. This temperature can be adjusted by the synthetic resin flexibility temperature. Moulds(3)(4)(5) are fixed on the both sides of the synthetic resin pieces inserted between the nails. Plate springs(6) (7)(8) are inserted in the holes(3a)(4a)(5a) along the moulds. A plate spring(10) is contacted on the plane portion of the resin pieces. The elasticity of the springs(6)(7)(8)(10) press the moulds and the synthetic resin pieces equally. This makes a fine bending plastic window after cooling.

Title: Barcode reading decorder system

Abstract: The system detects barcode data by  using  a  delta  distance method to prevent errors in  counting  bars  and  spaces  at  high speeds. The system detects an  optical  signal  scattered  from  a barcode, converts the optical signal  to  a  digital  signal,  and generates a toggle signal whenever the digital signal changes from a high potential to a low potential and vice versa with making  an opposite toggle signal to each of two types of the toggle signals. Respective width of these four types of toggle signals are counted and various signals necessary  to  read  data  of  a  barcode  are detected (4) by using a count signal.  An  I/O  memory  unit  (14) stores the outputs of a parity  check  unit  (11)  and  a  similar character discriminating unit (9).
