Disclosed is a cover film, which includes at least a base layer, an intermediate layer, a releasing layer and a heat seal layer that can be heat-sealed to a carrier tape, and wherein the heat seal layer contains, as a main component, a styrene-acrylic copolymer that has a mass average molecular weight of 5000 to 20000. This cover film is suppressed in variation in release strength when separated from the carrier tape, and is capable of reducing problems in the mounting process of electronic components such as rupture of the cover film during the separation.

There is provide a pneumatic radial tire for heavy loads capable of more effectively preventing a breakdown due to separation of a rubber chafer in an area corresponding to a bead heal portion than before. A pneumatic radial tire 10 for heavy loads has a pair of bead portions 12, a bead core 14 which is embedded in each of the bead portions 12, a radial carcass 16 extending from one bead portion 12 to the other bead portion 12 and turned around the bead core 14 from an inner side to an outer side of the bead portion 12 in a width direction of the tire to be anchored, a rubber chafer 22 disposed over the radial carcass 16 in the opposite side of the bead core 14. An angle θ formed by a steel cord 24S of the wire chafer 24 provided inside of the bead portion 12 outside of the radial carcass 16 and a carcass ply cord 16S of the radial carcass 16 is optimized depending on shear strain generated in the rubber chafer 22 so as to effectively preventing a breakdown of the rubber chafer 22 due to separation in an area corresponding to a bead heal portion 26.

An ultrasound probe comprises therapeutic transducers which include a plurality of arrayed first transducer elements and emit therapeutic ultrasounds to a subject, and diagnostic transducers which include a plurality of arrayed second transducer elements and emit diagnostic ultrasounds to the subject and receive the diagnostic ultrasounds, wherein the therapeutic transducers are stacked over the diagnostic transducers.
摘要:
A sound increase apparatus includes a partition wall adapted to divide an engine room for defining a first engine room space that is located on a side of a dash panel and a second engine room space in which an engine is installed, and a first pressure fluctuation amplification unit inter-communicating an engine inlet pipe arranged in the second engine room space and the first engine room space. The first pressure fluctuation amplification unit amplifies a pressure fluctuation of a first frequency selected from a plurality of frequencies when pressure of air residing inside the engine inlet pipe fluctuates at the plurality of frequencies.
