Patent number: 11973108Abstract: A semiconductor device includes: a drift region that is arranged on a main surface of a substrate, and has a higher impurity concentration than the substrate; a first well region that is connected to the drift region; and a second well region that is arranged adjacent to the first well region and faces the drift region. The second well region has a higher impurity concentration than the first well region. A distance between the source region that faces the drift region via the first well region and the drift region is greater than a distance between the second well region and the drift region, in a direction parallel to the main surface of the substrate. A depletion layer extending from the second well region reaches the drift region.Type: GrantFiled: December 1, 2020Date of Patent: April 30, 2024Assignees: NISSAN MOTOR CO., LTD., RENAULT S.A.S.Inventors: Wei Ni, Tetsuya Hayashi, Keiichiro Numakura, Toshiharu Marui, Ryouta Tanaka, Yuichi Iwasaki

Publication number: 20240133152Abstract: A work machine includes a vehicle body, a blade supported so as to be rotatable about a pitch axis with respect to the vehicle body, a pitch actuator connected to the blade, a first sensor, and a controller. The pitch actuator causes the blade to perform a pitch motion about the pitch axis in a forward tilt direction and a backward tilt direction. The first sensor detects a first parameter relating to a penetration force of a blade tip of the blade in a downward direction. The controller determines whether the penetration force is insufficient based on the first parameter, and controls the pitch actuator to cause the blade to perform the pitch motion in the forward tilt direction upon determining that the penetration force is insufficient.Type: ApplicationFiled: April 24, 2022Publication date: April 25, 2024Inventors: Kenichiro TANAKA, Yuichi NAKANO
