Abstract: An electrolytic capacitor includes an anode body, a dielectric layer that covers the anode body, a first solid electrolyte layer that covers the dielectric layer, and a second solid electrolyte layer that covers the first solid electrolyte layer. The first solid electrolyte layer contains a first conductive polymer that includes polypyrrole as a basic skeleton. The second solid electrolyte layer contains a second conductive polymer that includes polythiophene as a basic skeleton. The second solid electrolyte layer has a thickness of 1 ?m or more.

Abstract: An industrial two-layer fabric has an inner space between an upper side fabric and a lower side fabric. Some or all of upper side wefts or lower side wefts are secondary wefts interwoven with upper side warps or lower side warps so as to make the number of warps passing on an upper surface of the upper side fabric or passing on a lower surface of the lower side fabric larger than that on an inner space side of the upper or lower side fabric and a long crimp in the inner space is formed by the secondary weft.

Abstract: A dewatering and thickening belt having an endless fabric woven with synthetic resin filaments, a bending-resistant element and a guide protrusion, wherein the guide protrusion is fusion-bonded to a bending-resistant portion to which the bending-resistant element has been attached so that the outer end portion of the guide protrusion is located inside the end portion of the fabric. The inner end portion of the guide protrusion is located 20 to 50 mm outside the inner end portion of the bending-resistant element.

Abstract: 2-Oxabicyclo[3.3.0]octane compounds represented by the following formula (1) (compound (1)); an optical resolver comprising at least one of the compounds (1); a process for producing the compounds (1) which comprises reacting a compound (2) or compound (3) with an alcohol (5) in the presence of an acid catalyst; a method of separating a diastereomer mixture of a compound (1); and a method of optically resolving an alcohol with the optical resolver. [In the formulae, R1 to R10 each represents hydrogen atom, etc.; R11 represents an alkyl group, etc.; R12 represents a hydrocarbon group, etc.; R13 represents a hydrocarbon group, etc.; and A represents acetyl group, etc.

Abstract: A novel cyclopentanone derivative having a cyclopentanone or cyclopentanol ring having substituents at the 2- and 5-positions is provided. The cyclopentanone derivative preferably has 13 to 17 carbon atoms. A perfume composition comprising the cyclopentanone derivative emits a flora fragrance emphasizing a natural and fresh feeling. It is useful for perfuming a variety of toiletries and households. A process for preparing the above-mentioned cyclopentanone derivative is also provided by which the cyclopentanone derivative can be obtained in a practically acceptable yield.
