摘要： A sensor device for use in an automobile as an airflow sensor is composed of a silicon substrate in which a cavity is formed and a base plate bonded to the silicon substrate. An upper end of the cavity is closed with a thin membrane including a sensor element such as a temperature sensor element, while a lower end of the cavity is closed with the base plate. An air passage having a small cross-section is formed through the base plate, so that the cavity communicates with the outside air through the air passage. The thin membrane is prevented from being damaged by collision with foreign particles included in the airflow because the air in the cavity functions as a damper. The air passage may be made in the silicon substrate in parallel to its surface without using the base plate.

摘要： Magnetoresistive devices are formed on the insulating surface of a substrate made of silicon. The devices are connected in series through an insulating film using a wiring layer formed on the surface of the substrate. An insulating film for passivation is formed to cover the devices and the wiring layer. A magnetic shield layer of Ni—Fe alloy is formed on the passivation insulating film through an organic film for relieving thermal stress to cover one of the devices. After removal of the sensor chip containing the magnetoresistive devices and other components from the wafer, the chip is bonded to a lead frame through an Ag paste layer by heat treatment. Preferably, the magnetic shield layer is made of a Ni—Fe alloy having a Ni content of 69% or less.

摘要： A pressure sensor includes a connector case having a recess, in which a sensor chip is contained and an oil is filled. The recess filled with the oil is sealed by a metal diaphragm. The sensor chip for outputting signals and the circuit chip having a processing circuit for processing the signals from the sensor chip, are stacked. That is, the circuit chip is provided between a bottom wall surface of the recess and the sensor chip. The processing circuit is covered by at least a part of the sensor chip, and the processing circuit of the circuit chip is arranged at a place where the processing circuit can avoid contact with the oil. Because the processing circuit of the circuit chip is not exposed to the oil, the processing circuit can be effectively restricted from being charged due to a polarization of the oil.

摘要： A motor-assisted turbocharger is composed of a turbine driven by energy of exhaust gas, a compressor rotated by the turbine and a rotary electric machine for assisting rotation of the compressor. The turbine, the compressor and the rotary electric machine are connected to each other by a common rotating shaft. A polygon nut having magnetic member facing fixed magnetic sensor is connected to an axial end of the rotating shaft. A magnetic field formed between the magnetic member and the magnetic sensor changes according to rotation of the rotating shaft. A rotational speed and a rotational position (or angle) of the compressor are detected based on the changes in the magnetic field. Operation of the turbocharger is electronically controlled based on the detected rotational speed and the rotational position.
