Abstract: [Object] To provide a haptic presentation apparatus capable of quickly deforming a surface. [Solving Means] A haptic presentation apparatus includes a base material, an elastic layer, and a fluid transport apparatus. The base material forms a first space and includes a first through hole. The elastic layer covers a surface of the base material including the first through hole. The fluid transport apparatus injects fluid between the elastic layer and the base material via the first through hole. The elastic layer is expanded by injecting the fluid from the fluid transport apparatus such that an internal pressure of a second space between the elastic layer and the base material is higher than an internal pressure of the first space, and the fluid injected into the second space is vented to outside of the second space via a second through hole by stopping driving of the fluid transport apparatus.

Abstract: A semiconductor element drive device is provided to solve a problem that because a case of a change in the temperature of the semiconductor element or a current flowing through the semiconductor element is not take into consideration, switching loss and noise cannot be reduced sufficiently. In accordance with input sensing information (temperature T, current I), a timing control unit 3 outputs a delay signal Q to control timing of driving a current increasing circuit 5 so that a reduction of switching loss of an IGBT 101 is maximized. When the IGBT 101 is in turn-on mode or turn-off mode, the current increasing circuit 5 outputs a drive signal in response to the delay signal Q delayed by a given time from output of the drive instruction signal P. In this way, the current increasing circuit 5 increases the current that causes the gate capacitor of the IGBT 101 to be charged/discharged in response to the delay signal Q, thereby increasing a switching speed to reduce switching loss.
