摘要： PROBLEM TO BE SOLVED: To provide a technique capable of alleviating shocks received by a vehicle side and an obstacle side at the time of collision in a heat exchanger for a vehicle.
SOLUTION: A groove 4ba in parallel to a distributing direction of a heat medium distributed inside is indented. As a main characteristic of this invention, the indentation part 4ba is deformed at the time of collision, so as to loosen the shocks. Such constructed heat exchanger 4 for a vehicle is deformed from the indentation part 4ba, because a stress generated at the time of collision is collected. In this manner, the indentation part 4ba is provided, so as to easily deform the heat exchanger at the time of collision, thereby alleviating the shocks.

摘要： PROBLEM TO BE SOLVED: To enable a physical quantity to be detected under a higher pressure in a physical quantity detection device.SOLUTION: A physical quantity detection device 1 includes a sensitive layer 12 for detecting a physical quantity provided on a bearing 22. On the sensitive layer 12, the physical quantity detection device includes further an oxide film 13 and a silicon nitride film 14 sequentially from the side of the sensitive layer 12. Since the silicon nitride film 14 is harder than the oxide film 13, by disposing the silicon nitride film 14 on the side coming into contact with an external member, the sensitive layer is hard to subject to damages. In a case of disposing the oxide film 13 between the silicon nitride film 14 and the sensitive layer 12, since film stress is lower in the oxide film 13 than in the silicon nitride film 14, force transmitted to the sensitive layer 12 can be reduced.
摘要翻译：要解决的问题：能够在物理量检测装置中能够在更高的压力下检测物理量。解决方案：物理量检测装置1包括用于检测在轴承22上提供的物理量的敏感层12。物理量检测装置从敏感层12的侧面依次包括氧化膜13和氮化硅膜14.由于氮化硅膜14比氧化膜13硬，所以通过将氮化硅薄膜14在与外部构件接触的一侧，敏感层难以受到损害。在氮化硅膜14和敏感层12之间设置氧化膜13的情况下，由于氧化膜13中的膜应力低于氮化硅膜14，所以传递到敏感层12的力可以降低。

摘要： PROBLEM TO BE SOLVED: To provide an oil jet capable of performing oil jet more accurately corresponding to a piston temperature rise.SOLUTION: As illustrated in Fig.3, when an oil temperature is included in a medium oil temperature zone (e.g., in the vicinity of 50°C), a thermo-sensible deforming member 44 is deformed and a closed state of an oil inflow port 28a is canceled. Furthermore, when oil pressure is included in a medium oil pressure zone (e.g., in the vicinity of 150 kPa), a pressure system pressure valve 32 is maintained in an energized state but an oil temperature system pressure valve 38 is moved downward. As a result, as shown by an arrow in Fig.3, oil flowing in an oil passage 18 flows through an opening 24 and through an internal passage 28 into an oil jet passage 30. Oil having flown in is jetted out of an oil nozzle 22 towards an inner surface of a piston 14.

In addition, a decompression path PA is provided for communication between the crankcase and the intake system. A relief valve V3 for opening only when the pressure inside the crankcase is equal to or more than the set pressure is disposed in the decompression path.
