  • Publication number: 20220310316
    Abstract: In the multi-layer coil component, the hole portion is provided in the vicinity of the side surface of the element body, and the distance from the tip position of the external electrode to the hole portion is shorter than the distance from the tip position of the external electrode to the coil. Therefore, when a crack is generated starting from the tip position of the external electrode on the mounting surface, the crack progress toward the hole portion located at a distance closer than the coil. Therefore, in the multi-layer coil component, splitting of the coil due to the crack can be prevented.

  • Publication number: 20220055028
    Abstract: The present invention addresses the problem of providing a fluid handling system that is capable of injecting a fluid into a desired chip or the like without using a large-scale device. In order to resolve the problem, this fluid handling system has a reservoir, a flow path chip, and a cap, one end of which is fitted to the internal opening of the reservoir and the other end of which is connected to an introduction port of the flow path chip, the cap having a through-hole that links the one end and the other end. In this fluid handling system, a protruding part provided to the flow path chip is fitted into the through-hole at the other end of the cap and restricts blocking of the through-hole when a fluid moves inside the through-hole of the cap.

  • Patent number: 11127529
    Abstract: A method of manufacturing a laminated coil component is a method of manufacturing a laminated coil component provided with a laminate obtained by laminating a coil conductor forming a spiral coil and an insulator layer. The method of manufacturing a laminated coil component includes a step of providing a conductor pattern configured to become a coil conductor on a green sheet configured to become an insulator layer, and a step of laminating a plurality of green sheets provided with the conductor pattern. The conductor pattern includes a pair of first side surfaces opposed to each other in an orthogonal direction orthogonal to a laminating direction of the green sheet. At the step of laminating a plurality of green sheets, a depression is formed on at least one of the pair of first side surfaces.
