  • Patent number: 9123469
    Abstract: In a method of forming a plating layer for an external terminal electrode by applying, for example, copper plating to an end surface of a component main body with respective ends of internal electrodes exposed, and then applying a heat treatment at a temperature of about 1000° C. or more in order to improve the adhesion strength and moisture resistance of the external terminal electrode, the plating layer may be partially melted to decrease the bonding strength of the plating layer. In the step of applying a heat treatment at a temperature of about 1000° C. or more to a component main body with plating layers formed thereon, the average rate of temperature increase from room temperature to the temperature of about 1000° C. or more is set to about 100° C./minute or more. This average rate of temperature increase maintains a moderate eutectic state in the plating layer and ensures a sufficient bonding strength of the plating layer.

  • Patent number: 9111690
    Abstract: A method is used to manufacture a multilayer electronic component including a multilayer composite including internal electrodes having ends that are exposed at a predetermined surface of the multilayer composite. In the method, the exposed ends of the internal electrodes are coated with a metal film primarily composed of at least one metal selected from the group consisting of Pd, Au, Pt and Ag and having a thickness of at least about 0.1 ?m by immersing the multilayer composite in a liquid containing a metal ion or a metal complex. Then, a continuous plating layer is formed by depositing a plating metal on the ends of the internal electrodes exposed at the predetermined surface of the multilayer composite, and subsequently growing the deposits of the plating metal so as to be connected to each other. Thus, exposed ends of the internal electrodes are electrically connected to each other.

  • Patent number: 8890492
    Abstract: Starting and stopping an engine is automatically controlled based on a load without using a relay. An inverter engine-driven power generator has an alternator, a rectifying circuit, a DC/DC converter, and an inverter circuit. A load detection circuit is connected to an output of the inverter circuit in parallel. A load detection line of the load detection circuit is connected to an output line of the inverter circuit in parallel via resistors. A power supply formed of a battery is connected to the load detection line. A decision circuit outputs a load detection signal when a current having a preset value or more flows through the load detection line. A drive/stop CPU starts the engine in response to the load detection. The resistors are set at a resistance value which does not influence a load to which a generator output is supplied.

  • Patent number: 8797711
    Abstract: A region where a plating film constituting an external electrode is formed can be accurately controlled in an electronic component in which the external electrode is formed by directly plating a particular region in a surface of a component body. In a component body, a bump is provided in a position in which a region where an external electrode should be formed is partitioned. In a plating process, growth of the plating film constituting the external electrode is substantially stopped or delayed in the bump. As a result, a termination point of the growth of the plating film constituting the external electrode can be accurately controlled in the position of the bump.
