Title: Louver door board piece having lease pattern and air chamber and made of plastic and manufacture thereof
Inventor: NEN MEI
IPC: E06B9/386
Filed: 1993-12-03
Abstract: PURPOSE: To improve the decoration and heat insulating property of a louver door plate piece by foam-molding a plastic material having an irregular recessing and projecting pattern on its surface and a partially variable thickness and containing many air chambers. CONSTITUTION: A plate piece 20 constituting a louver door is formed by foam molding a plastic material having irregular patterns on its surface and irregular thickness zones 22, 23, and 24 on its cross section and containing many pore-like air chambers 25. At the time of forming the piece 20, polycarbonate is molded with an extruder controlled to 200-300 deg.C in temperature after the polycarbonate is maintained at 50-70% in moisture for about 6-10 hours or homogeneously agitated after adding an additive having a boiling point of 80-180 deg.C to the polycarbonate and foamed by utilizing the moisture or additive. Then the pattern is formed by performing constant-temperature control through a vacuum mold and the polycarbonate is made to show different patterns during day time and nighttime and to maintain a shielding action and a heat insulating action.  Therefore, a louver door having a light weight and an appearance property can be obtained.

Abstract: PURPOSE: To machine thermoplastic resin continuously by closing a discharge passage with a sieve pin when a sieve is located at a work position and connecting the discharge passage with the end sieve side when the sieve is located at a cleaning position. CONSTITUTION: A sieve pin 4 is located at a work position and an auxiliary passage 112 is opened to the sieved side R of a sieve 8 in a sieve chamber A. A discharge passage 17 is closed and synthetic resin passed through the sieve 8 flows through a partial passage 10, the auxiliary passage 112 and a parallel cleaning passage 15 into a flow-out passage 7. During operation of a sieve pin 4 cleaning of the auxiliary passage 112 is performed constantly by the sieved synthetic resin being discharged through the flow-out passage 7. When the sieve pin 5 is guided to a cleaning position, a channel 151 reaches a parallel cleaning passage 16 on the sieved side R of a sieve 9. The sieved synthetic passes through a sieve or a sieve set 9 and guides dirty particles collected at the end side S of the sieve 9 to a discharge passage 18 thus stripping the dirty particles from the sieve.
