Publication number: 20240097671Abstract: A semiconductor device includes a first transistor, a first drive circuit including a second transistor, and a second drive circuit including a third transistor. The second transistor and the third transistor are connected in series; and a connection node of the second and third transistors is connected to a gate electrode of the first transistor. The first transistor, the second transistor, and the third transistor are normally-off MOS HEMTs formed in a first substrate that includes GaN. The first drive circuit charges a parasitic capacitance of the first transistor. The second drive circuit discharges the parasitic capacitance of the first transistor.Type: ApplicationFiled: February 10, 2023Publication date: March 21, 2024Inventors: Toru SUGIYAMA, Noriaki YOSHIKAWA, Yasuhiko KURIYAMA, Akira YOSHIOKA, Hitoshi KOBAYASHI, Hung HUNG, Yasuhiro ISOBE, Tetsuya OHNO, Hideki SEKIGUCHI, Masaaki ONOMURA

Patent number: 11559636Abstract: Provided is a warming device which can efficiently warm a blood product and inhibit a liquid in a warming flow path from exceeding an upper limit temperature thereof when liquid delivery of the blood product is stopped. The warming device includes the warming flow path in which the blood product flows and a heat plate which is in contact with the warming flow path to supply heat to the warming flow path. On the heat plate, a heater in a predetermined pattern corresponding to the warming flow path is disposed. The heater is disposed such that an amount of heat generation toward the warming flow path decreases in stages from an upstream side toward a downstream side in the warming flow path and that a decrease rate of the amount of heat generation at each of the stages decreases from the upstream side toward the downstream side.Type: GrantFiled: September 27, 2017Date of Patent: January 24, 2023Assignee: MED-TECH INC.Inventors: Noriaki Yoshioka, Taisuke Funamoto
