  • Publication number: 20220307927
    Abstract: A force sensor includes a pressure-receiving member; a sensor substrate including a displaceable portion to be displaced under a load received by the pressure-receiving member, and piezoelectric resistors configured to electrically detect an amount of displacement of the displaceable portion; a base substrate having a sensor-mounting surface, and including electrical wiring portions electrically connected to the piezoelectric resistors; and a package substrate having a substrate-mounting surface and a pad surface provided with pad electrodes. The pressure-receiving member, the sensor substrate, and the base substrate are stacked in a normal direction to the substrate-mounting surface. When seen in the normal direction, an entirety of the displaceable portion is located within the pressure-receiving member. The pad surface is provided with, when seen in the normal direction, a fixing terminal at least a part of which overlaps at least a part of a first area that coincides with the pressure-receiving member.

  • Patent number: 7933098
    Abstract: A thin film magnetic head is disclosed that is capable of improving the thermal efficiency of a heater. A thin film magnetic head includes: a lower shield layer; an upper shield layer; a reproducing element that is provided between the lower shield layer and the upper shield layer; a recording element that is formed on the upper shield layer; a heater that generates heat to expand at least one of the reproducing element and the recording element such that the reproducing element and/or the recording element protrude toward a recording medium; and a shunt line that applies a reference potential that is equal to the potentials of the lower shield layer and the upper shield layer to a magnetic layer of the recording element. In the thin film magnetic head, the shunt line is connected to the magnetic layer of the recording element at a position that deviates from the center of a heat generating region of the heater in a track width direction.
