Abstract: An object of the present invention is to provide a polyolefin resin composition with excellent transparency, which is obtained by a method which is economically advantageous, and easily produces said composition, wherein said composition hardly generates white spots thought to be an insoluble part of a diacetal compound, while retaining the intact transparency imparted by the diacetal. A clarifier for polyolefin resins which comprises a combination of an acetal compound represented by the general formula (1) with a specific amount of a modifier represented by the general formula (2) or (3) is used. Thus, white spots thought to be an insoluble part of the diacetal compound can be significantly diminished.

Abstract: A pressure-sensitive adhesive composition with a pressure-sensitive adhesive property and heat resistance comprises a polyester having a polylactone structure as the main chain. A pressure-sensitive adhesive sheet with a releasing property of a peelable liner and containing no silicone can be obtained by using the pressure-sensitive adhesive composition in combination with a polyolefin film without being subjected to a silicone treatment as a peelable liner. When the pressure-sensitive adhesive sheet comprises a base material having formed thereon the layer of the pressure-sensitive adhesive composition and the back side of the base material has a surface composed of a polyolefin, neither a peelable liner nor a silicone treatment is required. The pressure-sensitive adhesive sheet is suitably used for computer instruments etc., because it contains no silicone.

Abstract: A tape cassette comprises pivotally supported first and second carriages having respective hubs rotatably carried thereby and wrapped with magnetic recording tape to form rolls of tape, a biasing spring for biasing the first and second carriages in a direction close towards each other, and a drive wheel rotatably supported inside the cassette and having a coupling disc adapted to receive a rotational force necessary to rotate the drive wheel. The rolls of tape on the respective hubs are, by the action of the biasing spring, forced to contact the drive wheel from opposite directions. In order to create a difference between the pressure of contact of one roll to the drive wheel and that of the other roll to the drive wheel when the tape cassette is in use, a friction element is provided for each of the carriages to impart a resistance to the corresponding carriage in a direction counter to the direction of pivotal movement of the corresponding carriage.
