Abstract:
In a method for manufacturing a multilayer ceramic electronic device, a resin introduction portion located outside a vertically projected region of a surface mount electronic device is disposed on a seat portion which includes a non-metallic inorganic powder as a primary component and on which the surface mount electronic device, e.g., a semiconductor element, is mounted, and a resin is supplied to the resin introduction portion so as to fill the resin into the seat portion and a gap between the seat portion and a multilayer ceramic element assembly. Unsintered ceramic base material layers and shrinkage restriction layers arranged to restrict shrinkage of the unsintered ceramic base material layers in a direction substantially perpendicular to a thickness direction of the unsintered ceramic base material layers are laminated and, thereby, an unfired multilayer ceramic element assembly is formed, which does not shrink in a direction substantially perpendicular to a lamination direction in a firing step.
Abstract:
An information output system includes a main memory, a first processing circuit, a second processing circuit, an output device, and notifying circuitry. The main memory is configured to store information. The first processing circuit is configured to read the information from the main memory. The second processing circuit is configured to transfer the information read. The output device is configured to output the information transferred. The notifying circuitry is configured to notify the second processing circuit of an activation timing of the first processing circuit. The second processing circuit is configured to start to transfer the information after being notified of the activation timing of the first processing circuit or request the first processing circuit to cancel reading of the information, according to a time by which the activation timing notified is delayed from an activation timing of the second processing circuit.
Abstract:
A via hole forming method and a multilayered board manufacturing method improve manufacturing yield by reducing the required processes. The via hole forming method includes a first step of forming a toner image by attaching toner particles, containing a conductive material and having a protruding portion, onto the surface of a first photosensitive member so that the protruding portion is directed to the outside; and a second step of opposing the surface of the first photosensitive member to one principal surface of a green sheet containing an insulating material and transferring the toner image to the one principal surface of the green sheet so that the protruding portions of the toner particles protrude into the green sheet so as to reach the other principal surface of the green sheet and the toner particles are buried in the green sheet. The via holes are formed using an electrophotographic printing method.

A packaging material with an electromagnetic coupling module for a RFID system, is constructed such that a radio IC chip is protected from external shock and environmental change without adversely affecting the planarity of the packaging material, the assembly of a radiator and an electromagnetic coupling module is facilitated, and the radiation characteristics are satisfactory. A packaging material includes a liner and a wave-shaped core material, wherein an electromagnetic coupling module and a radiator that are electromagnetically coupled to each other are arranged inside of the packaging material. The electromagnetic coupling module includes a radio IC chip and a feeder circuit board, on which the radio IC chip is mounted, the feeder circuit board including a resonant circuit that includes an inductance element. The radiator electromagnetically couples with the electromagnetic coupling module to transmit/receive high frequency signals.

A container includes an electromagnetic coupling module on an inner surface of a container main body and a radiator made of a metal material on an outer surface of the container main body. The electromagnetic coupling module includes a feeder circuit board, on which a radio IC chip is mounted and in which a feeder circuit including a resonant circuit that has a predetermined resonant frequency and includes an inductance element is provided. The electromagnetic coupling module and the radiator preferably transmit and receive high-frequency signals through electromagnetic coupling. The container thus has an electromagnetic coupling module that includes a radio IC chip that is resistant to a shock applied from the outside and an environmental change, realizes an easy arrangement of a radiator and the electromagnetic coupling module, provides a preferable radiation characteristic, and is suitably used in an RFID system.
Abstract:
In a composite body, a frame body to be connected to a first major surface of a substrate body includes a frame member made of an insulating material and a plurality of connection members formed by bending thin metal plates. The frame member includes a through-hole at the approximate center thereof and extends along a peripheral portion of the first major surface of the substrate body so as to define a frame shape. Each of the plurality of connection members has a first strip and a second strip continuously connected to opposed ends of a middle strip. The connection members are disposed in the frame member so as to face each other with the through-hole therebetween. Each of the first strip and the second strip of the connection member is exposed on a corresponding one of the two major surfaces extending around the through-hole of the frame member. The first strip and the second strip extend in a direction in which the connection members face each other with the through-hole therebetween, and the opposed ends of the middle strip are continuously connected to an end of the first strip and an end of the second strip on the side adjacent to the through-hole. The middle strip extends through the inside of the frame member.
