Abstract: A semiconductor device includes a semiconductor element and a first connection member. The semiconductor element includes a substrate and an electrode pad. The substrate includes a transistor formation region, in which a transistor is formed and which is shaped to be non-quadrangular. The electrode pad is located on the transistor formation region. The first connection member is connected to the electrode pad at one location. The electrode pad is arranged to cover a center of gravity of the transistor formation region in a plan view of the electrode pad. In the plan view, a connection region in which the first connection member is connected to the electrode pad includes a center of gravity position of the transistor formation region.

Abstract: A measurement device includes: a short-range wireless communication interface; a processor; and a storage. In a state where a communication connection with an information terminal using short-range wireless communication is established, the processor receives, from the information terminal, user information specifying a user of the information terminal, shares, with the information terminal, encryption information for performing encryption communication using short-range wireless communication, and stores the encryption information and the user information in the storage in association with each other.

Abstract: A display device includes a display unit having a panel-shape, a stand supporting the display unit, an adjusting mechanism being attached to the display unit and enabling the display unit to move up and down relative to the stand and turn around the stand, a first fastening member fastening the adjusting mechanism to the stand, and a regulating mechanism regulating the display unit from descending relative to the stand when the first fastening member is removed. The regulating mechanism includes a projection being formed on one of the stand and the adjusting mechanism, and a recess being formed in the other of the stand and the adjusting mechanism and being fitted onto the projection.

Abstract: An engine output control unit of a work vehicle is configured to set a target rotation speed of an engine by using an engine output torque curve, to control an output of the engine. The engine output control unit is configured to control the output of the engine so as to set torque to be higher than torque at an actual rotation speed obtained using the engine output torque curve. Typically, when the actual rotation speed of the engine becomes smaller than the target rotation speed, the engine output control unit sets an engine output torque curve that is greater in torque at the actual rotation speed than the engine output torque curve, and switches control of the output of the engine from control performed using the engine output torque curve to control performed using the engine output torque curve.

Abstract: A work vehicle detects pressure of hydraulic oil supplied to an arm cylinder. The work vehicle determines operation details for an arm. The work vehicle includes a relief valve capable of setting a relief pressure of hydraulic oil in a hydraulic circuit at one of a first set pressure and a second set pressure that is greater than the first set pressure. The work vehicle sets the relief pressure of the relief valve at the first set pressure, on the conditions that the detected pressure is equal to or greater than a predetermined value, and that it is determined that the operation details indicate an excavation operation. The work vehicle sets the relief pressure of the relief valve at the second set pressure when the conditions are not satisfied.
