Abstract: Described is a peelable heat shrink tube composed of a fluororesin and having a determination coefficient calculated from [Equation 1] below using an elastic modulus ratio (%) of more than 0, but 0.90 or less: Determination ? coefficient = ( correlation ? coefficient ) 2 = [ ( covariance ) ( standard ? deviation ? of ? X ) ? ( standard ? deviation ? of ? Y ) ] 2 [ Equation ? 1 ] where X, Y and covariance represent the following: X: Proportion of the position of each point, where the elastic modulus was measured, from the interior of the tube Y: Elastic modulus ratio in each region Covariance: Average of the product of deviations of X and Y.

Abstract: The present invention is a polymer composition, containing: 30 to 60 volume % of a melt processable fluoropolymer; and 40 to 70 volume % of boron nitride particles; wherein the boron nitride particles are made from particles (A) and particles (B), the particles (A) are spherical aggregate particles with an average particle diameter of 55 ?m to 100 ?m, and an aspect ratio of 1 to 2, the particles (B) are particles with an average particle diameter of 8 ?m to 55 ?m, and the volume ratio of the particles (A) to the total amount of boron nitride is 80 to 99 volume %. The polymer compositions have excellent moldability, insulation properties, heat conductivity, and heat resistance, and are suitable as raw materials for a sufficiently strong molded products, such as thin films.

Abstract: Provided is a thermoplastic resin composition having excellent thermal conductivity and high electrical insulating properties, and having excellent flexibility in comparison to ceramic molded bodies and thermoset resin compositions. The resin composition contains 20-60 volume percent of thermoplastic resin and 40-80 volume percent of boron nitride. The boron nitride is made up of spherical boron nitride particles and flat boron nitride particles. The spherical boron nitride particles have average particle size of 50-300 ?m and aspect ratio or 1-2. The flat boron nitride particles have average particle size of 8-100 ?m and aspect ratio of 30-300. The volume ratio of the spherical boron nitride particles with respect to the total amount of boron nitride is 75 vol %-99 vol %. Further provided are melt molded products of this thermoplastic resin composition and a method for the manufacture of such melt molded products.

Abstract: First tune information of playing information is read out from playing information storage means to a selected one of predetermined positions and then a selected one of a plurality of pieces of second tune information is read out without incurring the possibility of introducing discontinuity or unnaturalness between musical sounds reproduced from the first tune information and the second tune information.The predetermined positions on the first tune information are made to correspond to the plurality of pieces of second tune information, and control means is provided for controlling tune information read means so that when the first tune information has been read out to the selected one of the predetermined positions respectively corresponding to the plurality of pieces of second tune information, that one of the pieces of second tune information corresponding to the selected predetermined position is automatically read out.
