    Abstract: The invention provides a crosslinkable aromatic resin having a protonic acid group and a crosslinkable group, suitable for electrolytic membranes and binders used in fuel cells, etc., and electrolytic polymer membranes, binders and fuel cells using the resin. The crosslinkable aromatic resin has a crosslinkable group, which is not derived from the protonic acid group and can form a polymer network without any elimination component. This resin exhibits excellent ion conductivity, heat resistance, water resistance, adhesion property and low methanol permeability. Preferably, the crosslinkable group is composed of a C1 to C10 alkyl group directly bonded to the aromatic ring and/or an alkylene group having 1 to 3 carbon atoms in the main chain in which at least one carbon atom directly bonded to the aromatic ring bonds to hydrogen, and a carbonyl group, or a carbon-carbon double bond or triple bond.

  • Patent number: 6235825
    Abstract: A polylactic acid-based resin composition composed of a high molecular ingredient (A) comprising polylactic acid (a1) and an aliphatic polyester (B), and a film, particularly an inflation film, prepared from the resin composition. The film comprising the polylactic acid-based resin composition of the invention is biodegradable and excellent in flexibility and resistance to blocking of film and bleeding-out of plasticizer, has no anisotropy in tear strength, and can be suitably used for an agricultural multi-film and garbage bag.

  • Patent number: 5039847
    Abstract: Disclosed is an image processing apparatus capable of reading and processing both character data such as bar codes, optical readable letters and marks, and image data such as figures and tables by means of a single image scanner. The image processing apparatus has a parameter registration mode, a code addition mode and an image retrieval mode as operation modes. In the parameter registration mode, when a bar code corresponding to parameters related with image processing is read by the image scanner, a notification signal is outputted in response to completion of the reading. In the parameter registration mode, it is possible to determine priority to be assigned to either setting of the parameters through the image scanner or setting of the parameters through keys.
