It is an object of the present invention to provide a method for manufacturing a multilayered unit for a multi-layered ceramic electronic component which can reliably prevent short circuit failure from occurring 5 in a multi-layered ceramic electronic component. According to the present invention, a multi-layered unit for a multi-layered ceramic electronic component is fabricated by printing a conductive paste containing a butyral system resin as a binder and at least one solvent selected from a group consisting of dihydroterpinyl oxyethanol, terpinyl oxyethanol, d-dihydrocarveol, I-citronellol, I-perillylalcohol and acetoxy-methoxyethoxy-cyclohexanol acetate as a solvent on a ceramic green sheet containing an acrylic system resin as a binder in a predetermined pattern, thereby forming an electrode layer.

At the time of pressing an electrode layer 12a against a surface of a green sheet 10a having a thickness of 3 μm or thinner to bond the electrode layer 12a with the surface of the green sheet 10a, an adhesive layer 28 having a thickness of 0.02 to 0.3 μm is formed on a surface of the electrode layer 12a or the surface of the green sheet 10a. It is possible to easily transfer a dry type electrode layer to the surface of the green sheet with high accuracy without breaking or deforming the green sheet.

摘要:
The invention relates to an apparatus and method for data processing for IC tags and an image forming device capable of recording an image onto a conveying medium on which IC tags are mounted. The apparatus and method set up a state that enables reliable radio communication between a reader/writer and an IC tag and read and/or write electronic information from/to IC tags. The reader/writer's antenna to face IC tags mounted on the conveying medium, arranged in multiple rows and columns in the conveyance direction, is skewed so that the IC tags pass sequentially under the antenna and each IC tag can be identified. The reader/writer reads and/or writes electronic information associated with the thus identified IC tag.

The high damping material composition of the present invention containing the following components (A) and (B); (A) a polymer having in the molecular chain thereof a chemical structural unit derived from the following (a); (a) at least one selected from the group consisting of an acrylic monomer, a methacrylic monomer, an ethylene-acrylic copolymer, an ethylene-methacrylic copolymer and vinyl acetate; (B) at least one damping property imparting agent selected from the group consisting of a hindered phenol compound, a phosphite ester compound, a phosphate ester compound, a basic compound containing nitrogen and a hindered amine compound. The combined use of the component (A) and (B) makes an interaction therebetween homogeneous and appropriate, so that the component (B) is homogeneously dispersed in the component (A), resulting in exhibition of a high tan &dgr;. Moreover, the homogeneous dispersion can be maintained for a long period thereby to prevent a declined of tan &dgr; with time. The compositions have a tan &dgr; peak temperature of approximately room temperature, which makes the compositions suitable for use in a room temperature atmosphere.
