摘要:
A material comprising crosslinked polyrotaxanes which exhibits desired viscoelasticity, particularly stress-strain characteristics with a wide low-stress region, in spite of being free from solvent; and a process for production of the same. The material comprises a first polyrotaxane bearing first cyclic molecules and a second polyrotaxane bearing second cyclic molecules, and the first and second polyrotaxanes are crosslinked via the first and second cyclic molecules. The material is free from solvent and exhibits a stress of 2.0 MPa or below at 50% strain.

An actuator includes a spirally rolled cylindrical sheet body. The sheet body is formed by attaching an electrode on each side of a dielectric elastomer layer. When a voltage is applied to the electrodes, the sheet body is contracted along the direction of its thickness, and expanded in directions perpendicular to its thickness. The actuator is actuated by applying a voltage to the electrodes and stopping the voltage application, so that the cylindrical sheet body is extended and contracted along the direction of the axis. The material forming the dielectric elastomer layer has a low strain region, where the value of a strain based on a stress acting on the dielectric elastomer layer varies from zero to a value that is greater than and close to zero, and a high strain region, where the value of the strain is greater than that in the low strain region. The Young's modulus in the low strain region is less than the Young's modulus in the high strain region.

An optical measurement system which manages whether an optical property of a sample falls within a predetermined management range. The optical measurement system has a measuring device for measuring the optical property value of the inspected sample, a reader for reading an attribute identification information of an identification tag attached to the sample, and a storage section for storing optical property management information concerning a plurality of kinds of samples each in a manner corresponding to attribute identification information of each sample. A controller in the optical measurement system reads out from the storage section the optical property management information corresponding to the attribute identification information of the sample read by said reader, and compares the optical property management information with the optical property value of the sample, and then determines whether the optical property value falls within an allowable range in the optical property management information.

A protective film for polarizing plate is disclosed in which an contact angle of the surface in contact with a polarizer with respect to pure water is less than 55° and the surface in contact with a polarizer becomes hydrophilic due to a plasma treatment.In such a manner, the protective film for the polarizing plate is readily adhered with a polyvinyl alcohol film employed as a polarizer and can be produced employing processing which is safe in work and does not adversely affect the environment. Thus highly efficient protective film for the polarizing plate, which exhibits excellent adhesion with a polyvinyl alcohol film, and a polarizing plate employing the same, are provided.

Read buffers (RB0-RB3) are capable of holding data read out from a plurality of memory blocks (BNK0-BNK7) that are capable of parallel operation in response to a state in which the read data cannot be externally outputted from an external interface means; and, selection means (40, 41, 42) are provided for selecting data read out from one of the memory blocks, or data read out from one of the read buffers, and for feeding it to the external interface means, while the external-output-incapable state is not present. In this way, when there is a possibility that an output of read data will cause a resource competition, this read data is stored in a read buffer, and when there is no such possibility, then the read data can be externally outputted directly, thereby improving the throughput of read data output operations.
