Abstract: When thermoplastic is recycled by a general recycling process alone, only a low-quality recycled plastic material having physical property values lower than a virgin material can be obtained. A recycled plastic material of this invention is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing from the dried thermoplastic solid matter other than the thermoplastic.

Abstract: A porous absorbent can be formed using recycling materials, which makes it possible to provide at lower costs an excellent capability of absorbing ink or the like, as well as an excellent handling performance. The porous absorbent contains at least virgin fiber, old paper fiber of waste newspaper, and hemp fiber, and an ink jet recording apparatus is provided with such porous absorbent for absorbing waste ink discharged from the recording head thereof.

Abstract: Pure water (3) with a resistivity of 1 M&OHgr;·cm or more is externally supplied in an exposure apparatus in which a master and substrate are relatively moved and aligned by a stage driven by a linear motor (1) and a pattern on the master is transferred onto the substrate. While being adjusted to a predetermined temperature, the pure water (3) undergoes deoxidation processing and UV sterilization processing and is circulated to cool the linear motor (1).

Abstract: It is an object of this invention to provide a multilayered structure molded product formable by reusing a resin molded product. To achieve this object, a multilayered structure resin molded product including a core layer and a skin layer is molded using a pulverized resin material, which is formed by pulverizing a molded product molded from a thermoplastic resin material, as a resin material for forming the core layer, and a virgin material as a resin material for forming the skin layer.

Abstract: Disclosed herein is a process for producing a color filter substrate for picture device constructed by selectively arranging light-shielding members and a plurality of coloring members different in spectral characteristics from each other on a transparent base, which comprises the steps of forming a water-repellent layer composed of a silane coupling agent on the base on which the light-shielding members are partially formed, exposing the surface of the base to oxygen plasma, and arranging a plurality of the coloring members different in spectral characteristics from each other on transparent regions of the base.
