    • An optical storage medium of the present invention enables storage of data with high precision at high speed, and rewriting of data at high speed without an erasing process. Optical storage, reading and retrieving methods and optical storage, reading, and retrieving apparatuses using the medium are also provided. The optical storage medium has at least a polarization-sensitive member having the photo-induced birefringence property, such as a member made of polyester polymer having cyanoazobenzene as a side chain. The above apparatuses have spatial light modulator capable of modulating polarization. The modulator provides information of bit of two-dimensional data to each corresponding pixel by application or non-application of a voltage, and modulates the polarization of the beam incident on each pixel. Thereby, a signal beam transmitted through the spatial light modulator having a spatial polarization modulation corresponding to the two-dimensional data is obtained. The signal beam illuminates the optical storage medium, and at the same time, a reference beam illuminates the same region in the medium where the signal beam illuminates. Thus a hologram of the polarization modulation of the signal beam corresponding to the two-dimensional data is stored in the optical storage medium.
    • 本发明的光存储介质可以高速度地高精度地存储数据,并且无需擦除处理即可高速重写数据。 还提供光存储,读取和检索方法以及使用介质的光学存储,读取和检索设备。 光学存储介质至少具有光诱导双折射性的偏振敏感元件,例如由具有氰基偶氮苯作为侧链的聚酯聚合物制成的部件。 上述装置具有能够调制偏振的空间光调制器。 调制器通过应用或不施加电压向每个对应的像素提供二维数据位的信息,并且调制入射在每个像素上的光束的偏振。 由此,获得透过具有与二维数据对应的空间偏振调制的空间光调制器的信号光束。 信号光束照射光学存储介质,同时参考光束照射信号光束照射的介质中的相同区域。 因此,对应于二维数据的信号光束的偏振调制的全息图被存储在光学存储介质中。

    • The problem of this invention is to inhibit the infiltration of a lubricating oil supplied to the contact area of the shoe with the belt into the high molecular weight elastic member, and to offer a shoe press belt which has an excellent performance improving durability of the friction surface, preventing flaking off phenomena, cracks, and breakage; and its manufacturing method. An endless shoe press belt the inner portion 1a of which is adapted to contact a shoe S of a papermaking machine, said inner portion 1a being composed of a high molecular weight elastic material, characterized in that the surface of said inner portion is provided with a protective oil 3 comprising an oil the viscosity of which is higher than that of a lubricating oil J supplied to the contact area of said inner portion with said shoe, or a paste-like oil having a certain consistency. It effectively prevents infiltration of the lubricating oil into the surface of the inner portion of the belt.
