In one such embodiment, a drive controller is configured to calculate a basic motor-generator torque value based on the basic engine torque value and the target driving torque value, set a target engine torque to be the basic engine torque value and set a target motor-generator torque as the basic motor-generator torque value when the state of charge of the battery is within an allowable range, set the allowable range of the battery to be smaller when the transmission is performing the shift change operation and execute a basic value shift process when the battery is deviated from the allowable range. The basic value shift process suppresses deviation of the battery by shifting the target engine torque from the basic engine torque value and the target motor-generator torque from the basic motor-generator torque value.12-22-2011

20110075693SEMICONDUCTOR LASER - The present invention provides a semiconductor laser realizing reduced possibility that a wiring layer disposed in the air is broken even under severe environment of a large temperature difference. A trench is provided between adjacent ridges, and a wiring layer electrically connecting an upper electrode and a pad electrode is disposed in the air at least above the trench. The wiring layer in a portion above the trench has a flat shape or a concave shape which dents toward the trench. With the configuration, accumulation of strains in the wiring layer when the wiring layer repeats expansion and shrink under severe environment of a large temperature difference is suppressed.03-31-2011
