摘要： The present invention provides a method for producing an electrolytic capacitor including a porous body of a valve metal, an oxide film on a surface of the valve metal, and a conductive polymer layer on a surface of the oxide film. The step of forming the conductive polymer layer on the surface of the oxide film includes the steps of dipping the porous body in a monomer solution; lifting the porous body from the monomer solution and dipping the porous body in an oxidizing solution; and lifting the porous body from the oxidizing solution and allowing the porous body to stand. In the step of dipping the porous body in the oxidizing solution, a period for which the porous body is dipped in the oxidizing solution is equal to or shorter than a period in which 30% of the monomer contained in pores of the porous body diffuses and flows into the oxidizing solution. Alternatively, the volume of the oxidizing solution can be less than three times that of the porous body. The above method can be performed by replacing the monomer solution and the oxidizing solution with each other. Furthermore, a temperature of the porous body is maintained at a low temperature (e.g., 10.degree. C. or less) in the step of dipping the porous body in the oxidizing solution.

摘要： A method of preparing a composite sheet unit includes arranging a plurality of sintered piezoelectric thin wires in a uniform direction on a surface of a resin layer is prepared. A plurality of the same are laminated and integrated so that the sintered piezoelectric thin wires are positioned between the resin layers. Here, a curing resin may be impregnated therein so as to form resin-impregnated-cured portions. Then, the lamination is cut in a direction crossing a lengthwise direction of the sintered piezoelectric thin wires, so that a piezocomposite is obtained. Cut surfaces may be ground. By so doing, it is possible to provide a highly reliable piezocomposite having a fine structure at low cost, and to provide an ultrasonic probe for ultrasonic diagnostic equipment, as well as ultrasonic diagnostic equipment using the same.

摘要： A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value (13) is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.

摘要： A solid electrolytic capacitor is obtained in which a sintered metal serves as an anode and a silver layer serves as a cathode. A surface of sintered metal made of tantalum or the like and having an open porosity ratio of more than 75% is oxidized so that an oxide film made of tantalum pentoxide or the like is deposited thereon. Cavities of the metal are filled with an electrically conductive material. Then, the metal is wound around a lead wire and made into a desired shape and size. The silver layer is formed on this porous metal body. Because a specific surface area of the sintered metal is large, a large capacity is obtained.

摘要： A ceramic green sheet is obtained by forming a ceramic coating containing at least a ceramic raw material powder, a binder, and an organic solvent in a sheet shape, followed by drying. The binder contains two or more kinds of polyvinyl acetal with different average degrees of polymerization, and polyvinyl acetal with a higher average degree of polymerization contains a relatively large amount of hydroxyl group, and polyvinyl acetal with a lower average degree of polymerization contains a relatively small amount of hydroxyl group. This green sheet is subjected to binder-removal and firing, thereby obtaining a ceramic capacitor in which inner electrode layers 2 and dielectric layers 1 are laminated alternately and external electrodes 3 are sintered at both ends of the laminate. Consequently, a decrease in the sheet strength caused by a reduction in the thickness of the dielectric layers is suppressed, and there are provided a high-strength green sheet, a laminated ceramic article, and a method for manufacturing the same.
