Abstract: A power module and a power converter device including the power module include: two base plates with their main surfaces facing each other; a semiconductor circuit unit disposed between the two base plates; a connecting member that is connected to the two base plates and forms a housing region in which the semiconductor circuit unit is housed; and an insulating member that is placed between the base plate and the semiconductor circuit unit and secures electrical insulation of the base plate and the semiconductor circuit unit. A rigidity or thickness of the connecting member is less than a rigidity or thickness of the base plate.

Abstract: A variable valve timing mechanism comprises a drive shaft including a rocker arm, a control shaft, a stopper, a first spring member and a second spring member. The rocker arm opens and closes at least one of an intake/exhaust valve in response to rotation of the drive shaft. The control shaft changes a position of the rocker arm to continuously change valve lift characteristics of the intake/exhaust valve in response to rotation of the control shaft by driving a control shaft actuator. The stopper regulates an operating range of rotation of the control shaft between upper and lower limits. The first and second spring members urge the control shaft towards the upper and lower limits, respectively. The first and second spring members return the control shaft to a balance position between the upper limit position and the lower limit position when the internal combustion engine stops.

Abstract: A variable valve operating system for a two-bank engine includes a variable valve-lift and working-angle control mechanism changing at least one of a valve lift and a working angle of each of engine valves arranged in each of cylinder banks, and two variable valve timing control mechanisms provided for each of the banks for changing valve timings independently of each other. A control unit responds a failure in one of the variable valve timing control mechanisms for failsafe purposes. The control unit includes a failsafe section capable of executing a failsafe operating mode in which at least one of the valve lift and the working angle of each of engine valves is increasingly compensated for by the variable valve-lift and working-angle control mechanism, when the one variable valve timing control mechanism is failed.
