Patent number: 11864313Abstract: A multilayer wiring substrate according to the present invention includes a dielectric base body, a signal line in or on the dielectric base body, a ground conductor in the dielectric base body, and a graphite sheet in the dielectric base body. The dielectric base body is a laminate including dielectric sheets stacked on top of each other. The ground conductor and the signal line face each other in a stacking direction of the dielectric sheets. The ground conductor overlaps the signal line when viewed in plan in the stacking direction. The graphite sheet and the signal line face each other in the stacking direction without the signal line being located between the graphite sheet and the ground conductor. An upper surface of the graphite sheet is coplanar with an upper surface of the ground conductor or is located below the upper surface of the ground conductor.Type: GrantFiled: July 7, 2021Date of Patent: January 2, 2024Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Atsushi Kishimoto, Masatoshi Kakue, Shuichi Kawata, Hiroshi Nishikawa

Patent number: 11703040Abstract: A pump includes a pump flow path and electrodes and dielectric members in the pump flow path to allow a fluid to pass through the electrodes and the dielectric members in a flowing direction. The electrodes and the dielectric members are alternately stacked in the flowing direction so that a dielectric member is located between adjacent electrodes. Among the electrodes, an inter-electrode polarity of each pair of electrodes is different from that of an adjacent pair of electrodes. The dielectric members include a first dielectric member at a position of an odd-numbered dielectric member counted from the most upstream side of the flowing direction and a second dielectric member at a position of an even-numbered dielectric member counted from the most upstream side of the flowing direction. Material of the first and second dielectric members provide signs of a zeta potential opposite to each other.Type: GrantFiled: March 1, 2021Date of Patent: July 18, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Takafumi Moriasa, Shuichi Kawata, Masahiko Shigaki, Yuichi Kusano
