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 a control device for an internal combustion engine, in which actual maximum in-cylinder pressure in occurrence of preignition can be calculated accurately, even if an in-cylinder pressure sensor is deteriorated, by using a relation which is common before and after the deterioration of the in-cylinder pressure sensor.SOLUTION: A control device for an internal combustion engine stores: first normal maximum in-cylinder pressure measured by an in-cylinder pressure sensor before deterioration during normal combustion under a predetermined operating state; and a second normal maximum in-cylinder pressure measured by the in-cylinder pressure sensor after deterioration. In the case where preignition occurs in the predetermined operating state, a pressure ratio is calculated between second preignition maximum in-cylinder pressure measured by the in-cylinder pressure sensor after deterioration and the second normal maximum in-cylinder pressure. Based on the first normal maximum in-cylinder pressure and the pressure ratio, first preignition maximum in-cylinder pressure, which is actual maximum in-cylinder pressure in the occurrence of preignition, is calculated.
