摘要： An SOI substrate includes a thin diaphragm portion that is formed by removing a portion of the substrate from a rear surface side, and a thick outer frame portion that surrounds the diaphragm portion. A piezoresistive element that outputs an electrical signal in response to pressure is formed on the diaphragm portion, and an electrode that extracts the electrical signal from the piezoresistive element is formed on the outer frame portion. The electrode is disposed at a position on the outer frame portion that is separated by greater than or equal to 100 μm from a boundary line between the diaphragm portion and the outer frame portion.

摘要： A current limiter in an ignition apparatus for an internal combustion engine including a differential amplifier 20 is able to limit a primary winding current of an ignition coil to a prescribed limit value which is independent of a voltage as sensed by a current sensing resistor 11, thus providing a highly stable operating characteristic. The factor of current amplification of the differential amplifier can be increased without accompanying oscillations of the current limiter. The current sensing resistor senses a voltage corresponding to a current flowing from the primary winding of the ignition coil to a power transistor 4 which turns on and off the power supply to the ignition coil. A reference voltage source 12 generates a reference voltage for comparison with the voltage sensed by the current sensing resistor. A differential amplifier absorbs a part of a base current supplied from a storage battery to a base of the power transistor on the basis of a difference between the reference voltage and the voltage sensed by the current sensing resistor. A plurality of output transistors 25, 102 are coupled to form a Darlington circuit which is connected between the differential amplifier and the base of the power transistor. Another reference voltage source 12" may be provided for generating a second reference voltage, the second reference voltage source being connected between the current sensing resistor and the second input terminal of the differential amplifier for supplying thereto a total sum of the voltage sensed by the current sensing resistor and the second reference voltage.
