    摘要: A propylene-ethylene copolymer composition is obtained which has good moldability and an excellent balance of rigidity, toughness, and impact-strength. The composition has a melt flow rate of 10 to 300 g/10 minutes and is obtained by producing 60 to 95% by weight, based on the weight of whole polymer, of a propylene polymer having a melt flow rate (ASTM D1238) in the range of 100 to 1,000 g/10 minutes and having a ratio (Cf) of integrated values of the propylene polymer dissolved in o-dichlorobenzene at a temperature of lower than 112.degree. C., and a temperature of 112.degree. C. or higher, respectively, of 0.5 or less, by carrying out polymerization of propylene in the presence of a highly stereoregular catalyst and hydrogen in a polymerization step (I), and then producing 5 to 40% by weight, based on the weight of whole polymer, of an ethylene-propylene copolymer by feeding ethylene and propylene to the propylene polymer to react so that the content of ethylene becomes 30 to 80% by weight. Also provided is a propylene-ethylene copolymer composition comprising the composition mentioned above and a .alpha.-crystal and/or .beta.-crystal nucleator added therewith.

    摘要: An air conditioning system comprises an air conditioning unit, a blower for blowing conditioned air, a polygonal branch chamber of prescribed volume, a main duct with damper for delivering conditioned air from the blower to the polygonal branch chamber and branch ducts with dampers for delivering the conditioned air from the polygonal branch chamber to a plurality of discrete spaces. The polygonal branch chamber ensures quiet operation. An electrical circuit board is mounted on the bottom of the polygonal branch chamber and all wiring required for control of the dampers and other components of the system are connected with this board to enable maintenance work to be conducted at a signal location. A circular inspection hole with removable cover is formed in the bottom of the polygonal branch chamber to provide easy access to its interior. The dampers are integrated into damper pipe units including actuators, opening degree regulators and other components required for damper operation, further simplifying installation and maintenance work.

    摘要: The present invention is a sorter for products conveyed successively and continuously. The sorter components include a main screw rotated continuously by a drive shaft to arrange in order and convey products to be sorted. The main screw has helical grooves for engagement with the products and an annular groove portion for stopping therein each of the to-be-sorted products. The annular groove portion is positioned between helical grooves of the main screw. A rotatable sub-screw with helical grooves is located near the main screw at the annular groove portion for engagement with the products to be sorted. The sorter further includes a delivery means disposed at the annular groove to deliver the products from the main screw to the sub-screw and an interlocking mechanism rotating off the drive shaft which synchronizes the delivery means with the sub-screw. This sorter is a high speed, reliable system for sorting products undamaged.
