摘要:
A method of fabricating a thin film piezoelectric device includes preparing a semiconductor substrate having a surface; forming an etch stopping layer having an etching rate on the surface of the semiconductor substrate; forming a first semiconductor layer having an etching rate higher than the etching rate of the etch stopping layer on the etch stopping layer; forming a first electrode on a region of the first semiconductor layer; forming a piezoelectric film on the first electrode; forming a second electrode on the piezoelectric film; and etching a portion of the first semiconductor layer where the first electrode, the piezoelectric film, and the second electrode overlap, from the surface of the first semiconductor layer, selectively with respect to the etch stopping layer, thereby forming a cavity in the first semiconductor layer. Even when a compound semiconductor is employed as the substrate, the etching forming a cavity is stopped at the etch stopping layer in the direction perpendicular to the surface of the first semiconductor layer so that a cavity having a uniform depth is produced with high controllability.

摘要:
In the electrically heated catalytic converter system according to the present invention, the catalytic converter is provided with an electric heater. The electric heater is turned on by a switching device for a predetermined time period after the engine starts in order to heat the catalytic converter. When the switching device fails in such a manner that the switching device cannot turn off the electric heater even after the predetermined time period lapsed, the catalytic converter is heated by the electric heater even after the catalyst reaches the activating temperature. This may cause an excessive temperature rise and damage to the catalytic converter. The electronic control unit of the engine monitors the electric current supplied to the electric heater, and if the electric current is supplied to the electric heater continuously after the predetermined time period lapsed, the electronic control unit lowers the setting of the maximum limit of the speed of the engine to a value determined by the degree of opening of the throttle valve. Therefore, the engine is operated at a relatively low speed when the switching device has failed and the amount of the exhaust gas flowing through the catalytic converter is reduced. Thus the amount of the heat transferred from the exhaust gas to the catalytic converter is reduced, and an excessive temperature rise of the catalytic converter is suppressed.

An electrically heated catalytic converter system of the present invention includes a plurality of heater-converters, each heater-converter being disposed on one of a plurality of exhaust passages of an engine. Each heater-converter includes a catalyst bed which carries particles of a three-way reducing and oxidizing catalyst, an electric heater which is turned on during the start up of the engine to rapidly heat at least a portion of the catalyst bed, and a temperature detector disposed in the catalyst bed. The system also includes an electronic control unit (ECU) that detects the failure of the converter system. When the engine is started, the ECU calculates the difference in the temperatures of the catalyst beds, and if this difference in the temperatures becomes larger than a predetermined value, the ECU determines that one of the heater-converters has failed, i.e., the electrically heated catalytic converter system has failed. The failure of the converter system can also be determined by comparing the rate of temperature rise of the converters, or by determining a temperature or rate of temperature rise difference between a catalytic converter and the exhaust gas entering the catalytic converter.

The present invention provides an oil deterioration suppressing apparatus for an internal combustion engine comprising an oil reservoir section for reserving oil, a filtering component and an adsorption component provided in an oil passage, and a supply device for supplying the oil in the oil reservoir section to a side upstream of the adsorption component and the filtering component. The filtering component is configured to remove unnecessary products from the oil, and the adsorption component is configured to be positioned upstream of the filtering component to adsorb a predetermined acid component in the oil. Since the apparatus can remove a predetermined acid component in the oil from the oil in the adsorption component, it is possible to suppress generation of the sludge in the filtering component, thereby suppressing the oil deterioration appropriately.
