A seal structure for a gas turbine blade including a shank including a first side surface, a second side surface, and a bottom surface located radially inward from a fin. The first side surface has a recess movably housing a wedge seal, and a slot on the bottom surface as an insertion opening for a spline seal. The second side surface has a slot on the bottom surface as the insertion opening. The recess has an inclined surface extending straight radially inward and away from the first side surface. The wedge seal includes a wedge portion including a first wedge surface to be opposed to the inclined surface and a second wedge surface to be opposed to the second side surface of the adjacent rotor blade to form a wedge together with the wedge surface, and a weight portion positioned radially inward in the recess from the wedge portion.

A vehicle controlling apparatus includes an engine processor, an electric motor, an electric power storage, an SOC detector, an internal resistance detector, and a resistance threshold setting unit. The engine processor is configured to stop an engine of a vehicle on the basis of a stop condition, and start the engine on the basis of a start condition. The engine processor is configured to prohibit a stop of the engine based on the stop condition based on determining that an internal resistance of the electric power storage detected by the internal resistance detector is equal to or greater than a resistance threshold set by the resistance threshold setting unit on the basis of a state of charge of the electric power storage, and permit the stop of the engine based on determining that the internal resistance is less than the resistance threshold.

Vehicle controlling apparatus

An engine driving apparatus includes an engine, a starter motor, and a starter motor controller. The engine includes a plurality of cylinders. When any one of the plurality of cylinders enters a compression stroke, another one of the cylinders enters an expansion stroke. The starter motor is coupled to a crankshaft of the engine. The starter motor controller is configured to control the starter motor. Before restarting the engine, the starter motor controller performs pre-restart control for adding torque to the crankshaft by using the starter motor to open an exhaust valve of the cylinder in the expansion stroke.
