Abstract: The organic heteropolymer of this invention is useful for forming an organic semiconductor and is a copolymeric heteropolymer having a constitutional unit represented by the formula (1) and a constitutional unit represented by the formula (2): wherein M1 and M2 each represent a heteroatom selected from a group 8 element, a group 9 element, a group 10 element, a group 14 element, a group 15 element, and a group 16 element of the Periodic Table, and are different in group; M1 and M2 each have a valence v of 2 to 6; R1a and R1b each represent a halogen atom, an alkyl group, a cycloalkyl group, an aryl group, or a heteroaryl group; R2a and R2b each represent a halogen atom, an alkyl group, a cycloalkyl group, an aryl group, a heteroaryl group, a univalent or bivalent heteroatom selected from a group 16 element and a group 11 element of the Periodic Table, or a metal atom forming a complex with a ligand; m1, m2, n1, and n2 each denote 0 or 1; a ring Ar represents an aromatic ring; R3 represents a straight- or

Abstract: Inverted DI cans are fed by a conveyer having partitions in a plurality of rows such that they are spaced apart in each row, and treatment liquid is sprayed against the travelling cans from above and below the center of each row. The liquid is sprayed from above in a uniform and a full-cone pattern greater in area than the top surface of the can and from below also in a full-cone pattern or in a fan-shaped pattern narrow in the widthwise direction of the conveyer and greater in length than the can open end diameter. The liquid is further sprayed against the travelling cans from side nozzles on the opposite sides of and symmetric with respect to the center of each row. The side walls of the cans are thus washed without contact of adjacent cans in the direction of travel of the cans. The washing force is increased in the space between adjacent cans in the direction of travel to prevent washing irregularities and thus permit uniform surface treatment of the inner and outer surfaces of the cans.

Abstract: A drying arrangement includes transport device which uses suction or magnetism to produce an attractive force via which containers can be picked up by their bottom wall after they have come out of a washing station, and carried with an open end thereof oriented downwardly, over a nozzle arrangement which suctions off water in liquid form from the containers and over an arrangement which uses hot air to dry off the remaining water.

Abstract: A belt includes a plurality of rows of endless chains and can body conveying sections each defined between adjacent ones of the chains. Each of the endless chains are formed includes a plurality of U-shaped unit members each having a bottom fitted in an open end portion of a preceding one in the row, the engaged portions of the preceding and succeeding unit members being connected together by a plurality of rotatable connecting rods common to the chains. Intermediate rods having a length a little greater than the can body diameter are each provided between adjacent ones of the rods of the chains and also being opposed unit members of adjacent chains. The intermediate rods are disposed at a common elevation as the connecting rods beneath the top of the chains. Thus, the conveyer belt can convey can bodies in a plurality of rows in which the can bodies will not touch each other at the open ends of these can bodies.
