摘要： A covered acceleration sensor element includes a weight portion, a support frame portion surrounding the weight portion, a plurality of flexible beam portions for connecting the weight portion to the support frame portion to support the weight portion, piezoresistance elements provided on the beam portions, and wirings for connecting them. An upper cover and a lower cover enclosing the periphery of the weight portion together with the support frame portion are joined to the face and back of the support frame portion. Acceleration in the directions of three axes, i.e., a first axis in the joining thickness direction, a second axis in a plane perpendicular to the first axis, and a third axis in the plane and perpendicular to the second axis, or acceleration in the direction of any of the axes, is detected from changes in the resistances of the piezoresistance elements. The support frame portion is separated by separation grooves into an inner frame and an outer frame. The upper cover and the lower cover are joined to the outer frame. The inner frame is connected to the outer frame by a plurality of inner frame support portions having flexibility. The beam portions are connected to both sides of the weight portion along the second axis and the third axis. The inner frame support portions are connected to both sides of the inner frame in a direction in which they are rotated nearly 45 degrees from the second axis and the third axis.

摘要： A switching power supply circuit preventing coil current reversal, while minimizing a current consumption and speeding up a switching frequency is provided. The switching power supply circuit under a synchronous rectification system compares a feedback voltage and a reference voltage by a comparator and, based on the results of the comparison, alternately turns on and off a main switching element and a subordinate switching element to convert a direct current input voltage into a direct current output voltage. The circuit includes: an on-time generation circuit which, based on the input voltage and the output voltage, defines the on-times of the main switching element and the subordinate switching element; and a switching signal generation unit which, based on the output signals of the comparator and the on-time generation circuit, generates switching signals for controlling the on/off operation of the main switching element and the subordinate switching element.
