  • Patent number: 8617653
    Abstract: It is disclosed an over-coating agent for forming fine patterns which is applied to cover a substrate having photoresist patterns thereon and allowed to shrink under heat so that the spacing between adjacent photoresist patterns is lessened, with the applied film of the over-coating agent being removed to form fine patterns, further characterized by comprising a water-soluble polymer which contains a monomeric component and a dimeric component, wherein the total content of the monomeric component and the dimeric component in the water-soluble polymer is reduced to 10 mass % or less, and a method of forming fine patterns using the same. By the present invention, even in reducing the pattern size on a substrate having thereon patterns having different pitches, the heat shrinkage of the over-coating agent can be controlled, irrespective whether the pitch is dense or isolate, thus achieving the pattern size reduction.

  • Patent number: 8052014
    Abstract: A dual storage system-type fluid container in which a liquid pouring tube is securely fitted and a liquid discharging passage formed in a dispenser is easily and securely connected to the liquid pouring tube. A joint for the fluid container comprises a flexible bag (12) having a neck part (11) opened such that liquid can be poured through it and also has an outer container (13) for receiving the bag (12) with the neck part (11) supported by a mouth part (13a). The liquid pouring tube (15) having a flange part (15a) can be fitted to the mouth part (13a) of the outer container (13) with a retainer (14) placed between the tube and the mouth part. A flow passage (21a) formed in the dispenser (2) can be directly connected to the fluid passage (15b) of the liquid pouring tube (15).

  • Publication number: 20090230132
    Abstract: A fluid container in which a packaging bag with a spout is not likely to break due to a pin hole or breakage of an edge of the bag during storage or transportation, that has superior cleanliness for fluid contents, in which the packaging bag can be attached to and detached from an external container, and that is superior in working efficiency and hygiene. The container (1) has an external container (20) having an opening portion (24) and the spout-equipped packaging bag (10) used as the inner bag of the external container (20) and having the spout (11) joined to a packaging bag body (12). The packaging bag body (12) is receivable in the external container (20). The spout (11) is attachable to and detachable from the opening portion (24) of the external container (20). The packing bag body (12) is formed as a bag body by forming a heat seal portion (122) about the periphery of at least two sheets of films.
