摘要： (A) a polycarbonatediol, (B) a trifunctional alcohol, and (C) a diisocyanate are subjected to reaction in the presence of (D) a (meth)acrylate compound represented by the general formula CH2═CRCO(OCnH2n)pR′ or CH2═CRCO(OCmH2m)qOCOCH═CH2, and (E) a di(meth)acrylate compound of alkylene glycol whose alkylene group is substituted as a lower alkyl group, and then (F) a hydroxyl group-containing (meth)acrylate is added to the resulting solution of urethane oligomers in (meth)acrylate to conduct terminal (meth)acrylating reaction of the urethane oligomers, thereby producing a UV-curable liquid polyurethane resin having a viscosity (25° C.) of preferably 150,000-1,000,000 mPa·s, where before or after the terminal (meth)acrylating reaction of the urethane oligomers (G) a photopolymerization initiator and (H) a hindered phenol-based antioxidant having a molecular weight of 500-2,000 are added thereto to form the UV-curable liquid polyurethane resin. The UV-curable liquid polyurethane resin can produce HDD gaskets, etc. in a cross-sectional shape with a good sealability by an automatic coating robot efficiently.

摘要： A sealing structure sealing a clearance between a base (1) having a storage part (11) and a cover (2) joined to the base (1) so as to close the storage part (11) through a gasket (4) formed of a rubber-like elastic material. The base (1) and the cover (2) comprise side peripheral surfaces (12a) and (22a) opposed to each other in a direction different from a joining direction with a screw member (3). The gasket (4) is integrally fitted onto the side peripheral surface (12a) of the base (1) (or the side peripheral surface (22a) of the cover (2)), and the seal surface (41a) of the gasket is closely fitted to the side peripheral surface (22a) of the cover (2) (or the side peripheral surface (12a) of the base (1)). Thus, the outer shell of a device formed of the base (1) and the cover (2) can be easily thinned and the cover (2) can be prevented from being nonuniformly deformed by the repulsion of the gasket (4).
摘要翻译：一种密封结构，其密封具有储存部分（11）的基座（1）与接合到所述基座（1）的盖子（2）之间的间隙，以便通过由橡胶状弹性材料。基部（1）和盖（2）包括在与螺钉构件（3）的接合方向不同的方向上彼此相对的侧周面（12a）和（22a）。垫圈（4）整体地装配到基座（1）的侧面（12a）（或盖子的侧面部分）上，并且密封表面41a的密封面垫圈紧密地配合到盖（2）（或基部（1）的侧周面（12a））的侧周面（22a）上。因此，由基部（1）和盖（2）形成的装置的外壳可以容易地变薄，并且可以防止盖（2）由于垫圈（4）的排斥而不均匀地变形。
