Abstract: A controller is a control device for a transmission, the transmission provided in a vehicle and having a variator and a rotation sensor. The controller decides electrical abnormality of the rotation sensor when an electrical abnormality detection state of the rotation sensor is continued for a set time. The controller also decides functional abnormality of the rotation sensor when rotation speed is included in an abnormality detection region of the functional abnormality, and inhibits a decision on the functional abnormality during counting of the set time.

Abstract: A semiconductor device includes a base member, a first structure body, a second structure body, a first contact portion, a second contact portion, and a first post. The first structure body is provided above the base member. The first structure body has a first terrace in a front surface of a first end portion of the first electrode layer. The second structure body is provided on the first structure body other than the first end portion. The second structure body has a second terrace in a front surface of a second end portion of the second electrode layer. The side surface of the second electrode layer is at a first level difference between the first terrace and the second terrace. The first post is disposed between the first contact portion and the second contact portion. The first post crosses the first level difference.
