  • Publication number: 20090030177
    Abstract: A polymer for use in photoresist compositions is synthesized by effecting polymerization reaction to form a polymerization product mixture and subjecting the mixture to molecular weight fractionation by a liquid phase separation technique using a good solvent and a poor solvent. The fractionation step is iterated at least twice, and one iteration of fractionation includes adding a good solvent which is different from the good solvent added in the other iteration of fractionation.

  • Patent number: 7476275
    Abstract: An efficient coating machine capable of hardening coating on works in a short hardening time with a small-sized hardening oven at reduced costs. The coating machine has a painting booth, a hardening oven and a work transfer device. The work transfer device has a rotary shaft provided at a center of the coating machine, and a plurality of hangers, each holding one piece of work and being turnable about the rotary shaft. The painting booth and the hardening oven are arranged around the rotary shaft into an arc-shaped configuration, respectively. The hardening oven has an arc-shaped work passage adapted to move the works. One piece of work is coated in the painting booth and continuously transferred to the work passage of the hardening oven while being held with each of the hangers and turned about the rotary shaft.

  • Publication number: 20080110102
    Abstract: A weather strip has a trim part 5 to be attached to a peripheral part of a door opening corresponding to a door and a sealing part projecting from the trim part 5 and having a hollow part. The weather strip is obtainable by coating a treatment liquid containing a simple sulfur, a sulfur compound, or both of the simple sulfur and the sulfur compound on an outer surface of the sealing part of an extruded, non-vulcanized, and non-foamed intermediate molded body and vulcanizing and foaming the intermediate molded body by passing the intermediate molded body through a heating zone. By the above production steps, in the trim part, a skin layer that is harder than a sponge layer is formed on the sponge layer and a superficial part of the trim part. The skin layer has a width of 10 mm or more in a width direction and a uniform thickness set in a range of 0.04 mm to 0.15 mm.
