Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a valve timing control device which can obtain an appropriate holding control value upon starting or during cold operation, and which can prevent occurrence of detrimental affection upon an engine, such as inferior acceleration. SOLUTION: In order to realize a change of opening and closing timing of an intake valve 21 for an engine 20, a variable valve timing mechanism (VVT) 50 which is hydraulically driven, is provided. The VVT 50 is controlled through duty control of an oil control valve (OCV) 80 by an electronic control device (ECU) 70. During operation of the engine 10, the ECU 70 suitably updates a holding duty value. During starting or cold operation of the engine 10, the ECU 70 uses a learned holding duty value as the holding duty value. Upon leaning, the ECU 70 allows updating of the holding duty value under leaning only when the temperature of cooling water is higher than a predetermined value. Thus, a holding duty value adapted to be used upon next starting or during next cold operation can become substantially appropriate.

IPC: H01L23/31
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which can maintain a high reliability as a product without decreasing its productivity even under severe service conditions. SOLUTION: In a semiconductor device 11, a flexible setting resin 18 more flexible than a sealing resin 19 and insulating protective layers 17 is provided between ends 19a of the sealing resin 19 and the protective layers 17. Even when the device is used under a condition of a large temperature change, a stress caused by differences in linear thermal expansion coefficient between the sealing resin 19 and the setting resin 18 and between setting resin 18 and the protective layer 17 is small. Therefore, the stress generated between the resin 19 and the protective layer 17 can be lightened and thus peeling off of the sealing resin 19 can be prevented. In this case, it can be made unnecessary to use such a special material as hard to obtain and expensive as the material of the sealing resin 19.
