Abstract: A tempo analyzer to analyze the tempo of sound such as a musical composition or the like is provided in which a controller (9) takes, based on level information on a sound signal from an analysis data extraction unit (62), a frame which is a predetermined unit-time interval as a unit of process, detects positions of peaks of the level of the sound signal (apex of the change in level) higher than a predetermined level to find a time interval (peak-to-peak interval) between the peak positions in the frame, and determines a peak-to-peak time interval having occurred frequently as a tempo.

Abstract: A label having a thermoplastic polymer film and an ink layer formed on at least one surface thereof, the ink layer being removable in alkaline hot water, can easily be recycled after separated or without being separated from the bottle into polymer pellets with improved purity. The recycled polymer pellets are extremely suitable for the effective use of resources because they contain substantially no ink and can therefore find various applications.

Abstract: A molding material for thermoplastic composites is provided. The molding material is prepared from a commingled yarn containing continuous thermoplastic fibers and continuous reinforcing fibers, in a form of threads, textile fabrics, knitted fabrics, or multiaxial laminated fabrics, wherein the fiber commingling parameter of said continuous reinforcing fibers in said commingled yarn is 20% or more, and wherein the orientation index after heat treatment of said continuous thermoplastic fibers is 0.3 or more, and/or the thermal shrinkage ratio of said continuous thermoplastic fibers is 15% or less.

Abstract: In a thermo-shrinkable polyester film, the thermal shrinkage ratio in a main shrinking direction is about 20% or more after being treated in water of about 70.degree. C. for about seconds, about 35 to about 55% after treated in water of about 75.degree. C. for about 5 seconds, and about 50 to about 60% after being treated in water of about 80.degree. C. for about 5 seconds. After the film is shrunk by about 5% by treatment in water of about 75.degree. C. for about 10 seconds, the probability of the elongation at rupture of the film in the direction perpendicular to the main shrinking direction being about 20% or less, is about 10% or less. The ratio of .tau..sub.1 /.tau..sub.2 is about 0.05 to about 0.45, where .tau..sub.2 is the stress of shrinkage in a main shrinking direction of the film at about 90.degree. C., and .tau..sub.1 is the stress of shrinkage in a direction perpendicular to the main shrinking direction of the film at about 90.degree. C. The sealing strength of the film is about 1.

Abstract: Heat-shrinkable polyester films having a heat shrinkability of 30% or more, preferably 40% or more, in the direction of major shrinkage after treatment in hot water at 80.degree. C. for 30 seconds, the ratio of heat shrinkability in the direction of major shrinkage after treatment in hot water at 80.degree. C. for 5 seconds to heat shrinkability in the direction of major shrinkage after treatment in hot water at 80.degree. C. for 30 seconds being 0.8 or less, preferably 0.7 or less. The heat-shrinkable polyester films are suitable for label applications because of their particular heat-shrinkable properties such that not only do they scarcely cause longitudinal sinking when shrunk but also they have very few wrinkles, shrinkage spots and strains remaining after shrinkage.

Abstract: A polyester film having a coefficient of dynamic friction between the film and a metal at 80.degree. C. of not more than 0.45, a polyester film composed of a polyester comprising an ethylene terephthalate unit in a proportion of 70% or more by mole, the polyester film comprising a cyclic ethylene terephthalate trimer in a proportion of 0.7% or less by weight, laminated metal sheets and metal containers manufactured from said laminated metal sheet. According to the present invention, the polyester film shows superior sliding property and superior scratch resistance during can production, as well as the elution of oligomer from the film can be suppressed, so that when the film is used for metal containers for food, the change in and smell of the food contained therein and degraded appearance of the surface of the film caused by the deposition of oligomer are avoided.
