  • Publication number: 20180068789
    Abstract: A composite sheet includes a ceramic green sheet having a lengthwise direction and a conductor film printed on the ceramic green sheet. The conductor film has a shape that has a longitudinal dimension extending in the lengthwise direction and a lateral dimension perpendicular or substantially perpendicular to the longitudinal direction. The conductor film includes a plurality of thickness-varied regions arranged in a row or a plurality of rows extending in the lengthwise direction while being dispersed in the lengthwise direction. The thickness-varied regions have a thickness that is different from a thickness of a portion of the conductor film excluding the thickness-varied regions.

  • Patent number: 9782762
    Abstract: Provided is a mononuclear ruthenium complex that comprises a ruthenium-silicon bond that is represented by formula (1) and that exhibits excellent catalyst activity in each of a hydrosilylation reaction, a hydrogenation reaction, and reduction of a carbonyl compound. In formula (1), R1-R6 either independently represent an alkyl group, an aryl group, an aralkyl group or the like that may be substituted with a hydrogen atom or X, or represent a crosslinking substituent in which at least one pair comprising one of R1-R3 and one of R4-R6 is combined. X represents a halogen atom, an organoxy group, or the like. L represents a two-electron ligand other than CO and phosphine. When a plurality of L are present, the plurality of L may be the same as or different from each other. When two L are present, the two L may be bonded to each other. n and m independently represent an integer of 1 to 3 with the stipulation that n+m equals 3 or 4.

  • Patent number: 9271434
    Abstract: A manufacturing method for an electronic component forms with a high degree of accuracy a portion of an outer electrode on a main surface of a dielectric block. Light irradiated from a second main surface side is detected by a detector disposed on a first main surface side, thereby detecting the positions of first and second inner electrodes, and a conductive layer is formed in a portion on a first main surface, determined based on the detection result by the detector, thereby forming first portions of individual first and second outer electrodes.

  • Patent number: 9039859
    Abstract: A ceramic green sheet laminate is produced by stacking ceramic green sheets, each including conductive films for forming first or second internal electrodes on a surface thereof. A first cutting step is performed in which the ceramic green sheet laminate is cut to form first and second end surfaces at which the first or second internal electrodes are exposed. A second cutting step is performed in which the ceramic green sheet laminate is cut to form first and second side surfaces at which the first and second internal electrodes are exposed. In the second cutting step, the ceramic green sheet laminate is pressed and cut by moving a cutting blade in a length direction or a width direction.
