Publication number: 20220310316Abstract: 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.Type: ApplicationFiled: March 28, 2022Publication date: September 29, 2022Applicant: TDK CORPORATIONInventors: Yuya OSHIMA, Kenji KOMORITA, Masayuki SUZUKI, Yuudai KATOU, Takeru SASAKI, Shigeshi OSAWA, Takehiro ISHII, Kouichi KAKUDA, Yukio TAKAHASHI, Tsubasa OZAWA, Makoto YOSHINO

Publication number: 20220055028Abstract: 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.
