摘要： A gallium nitride-based semiconductor optical device is provided that includes an indium-containing gallium nitride-based semiconductor layer that exhibit low piezoelectric effect and high crystal quality. The gallium nitride-based semiconductor optical device 11a includes a GaN support base 13, a GaN-based semiconductor region 15, and well layers 19. A primary surface 13a tilts from a surface orthogonal to a reference axis that extends in a direction from one crystal axis of the m-axis and the a-axis of GaN toward the other crystal axis. The tilt angle AOFF is 0.05 degree or more to less than 15 degrees. The angle AOFF is equal to the angle defined by a vector VM and a vector VN. The inclination of the primary surface is shown by a typical m-plane SM and m-axis vector VM. The GaN-based semiconductor region 15 is provided on the primary surface 13a. In the well layers 19 in an active layer 17, both the m-plane and the a-plane of the well layers 19 tilt from a normal axis AN of the primary surface 13a. The indium content of the well layers 19 is 0.1 or more.

摘要： A system (1) for cooling EGR gas and lubrication oil, which is compact, resistive to vibration, and heats the lubrication oil at cold start of an engine (2) while cooling EGR gas. A system housing (10) is directly attached to a lateral wall of a cylinder block (3) such that engine cooling water flows therein. An EGR gas heat exchanger (16) and oil heat exchanger (15) are located in the housing (10) and immersed in the cooling water. Since the two heat exchangers (15, 16) are placed close to each other, high temperature EGR gas flowing in the EGR gas heat exchanger (16) heats low temperature lubrication oil flowing in the oil heat exchanger (15) via the cooling water when the engine (2) is cold. As a result, the viscosity of the lubrication oil drops and it assists easier start up of the engine under a cold condition. Since the single housing (10) is shared by the two heat exchangers (15, 16), the system (1) is compact.
