Abstract: A window structure of a vehicle body, comprises an inwardly offset flange structure defining a window opening therein, the inwardly offset flange structure including inwardly bent walls which have substantially straight wall portions and curved corner wall portions each merging into adjacent two of the straight wall portions; a window panel secured to the flange structure for closing the window opening, the window panel having an edge wall which includes a plurality of substantially straight edge wall portions respectively spaced apart from the straight wall portions and a plurality of curved corner edge wall portions each merging into adjacent two of the straight edge wall portions and respectively spaced apart from the curved corner wall portions, each of the straight edge wall portions and each of the straight wall portions forming a straight gap therebetween, and each of the curved corner edge wall portions and each of the curved corner wall portions forming therebetween a curved corner gap which merges i

Abstract: A molding member is installed and supported on the outer surfaces of supporting members which are mounted on the flange portion of a backdoor of a motor vehicle and the edge portion of a window of the same which are secured to each other. Each supporting member is of E-shape defining first and second spaces therein, in which the flange portion of the backdoor is securely disposed in the first space and the edge portion of the window is securely disposed in the second space.

Abstract: A transparent polyester film having excellent printability, flexing resistance and pinhole resistance and further excellent interlaminar strength, which is made from a polymer mixture or blend comprising (i) a polyester consisting essentially of a residue of dibasic acids wherein at least 80 % by mol is terephthalic acid and a residue of at least one glycol and (ii) a block copolyester consisting of a crystalline polyester (hard) segment having a high melting point and a soft polymer segment having a low melting point and a number average molecular weight of 400 to 8,000, said soft polymer segment having a low melting point being contained in an amount of 0.5 to 10 % by weight on the basis of the whole weight of the polymer mixture or blend, and said crystalline polyester segment having a melting point of at least 170.degree. C when a polymer is produced by the monomers composing the segment alone and said soft polymer segment having a melting or softening point of 100.degree. C or lower.

Abstract: A polyester block copolymer film excellent in slip characteristics and blocking resistance, which is prepared by melt extruding a polyester block copolymer in a film and cooling the film in a melt state at a temperature of about 40.degree. to 120.degree.C to solidify it, the polyester block copolymer comprising crystalline polyester segments and non-crystalline polymer segments in a weight ratio of 99 : 1 to 10 : 90 and having a number average molecular weight of about 10,000 to 100,000, the melting point of a self-supporting high polymer substantially constituted with the monomer components of the said crystalline polyester segments alone being not lower than about 200.degree.C and the melting point or softening point of a polymer substantially constituted with the said non-crystalline polymer segments themselves being not higher than about 80.degree.C.
