Abstract: A pressing sensor is provided that generates an output voltage of a first polarity by deforming with an operation plate when a part of a user's body touches the operation plate, and generates the output voltage of a second polarity by deforming with the operation plate when the part of the user's body is moved away from the operation plate. Moreover, a calculation unit calculates an electrical parameter integral value by time-integrating an electrical parameter that changes with the output voltage generated by the pressing sensor. The electrical parameter has a third polarity when the output voltage has the first polarity and has a fourth polarity when the output voltage has the second polarity. The calculation unit calculates a subtraction electrical parameter integral value obtained by subtracting a predetermined value having the third polarity per unit time from the electrical parameter integral value.

Abstract: In a surface acoustic wave resonator, a first IDT electrode defining a first IDT and a second IDT electrode defining a second IDT are located on a first principal surface of a piezoelectric substrate. A direction of an electric field applied to the first IDT electrode and a direction of an electric field applied to the second IDT electrode are opposite to each other with respect to a direction of a projected axis resulting from projecting a c-axis of the piezoelectric substrate to the first principal surface of the piezoelectric substrate.

Abstract: A pointer includes: a pointer tip having a tip configured to point a position; a transmitter configured to emit a signal from the pointer tip; and a main body connected to the pointer tip. The main body includes: an exterior housing forming an exterior; a detector configured to detect displacement of the exterior housing and output a detection signal; and a controller configured to change an operation state of the pointer in accordance with the detection signal. The detector includes: a detection device provided on an inner surface of the exterior housing and configured to detect the displacement; and a signal outputter configured to output the detection signal in the case where the detection device detects the displacement.
