摘要： A resolver for detecting the displacement amount of a passive body is provided with an excitation winding or a detection winding. The detection is based on a detection signal outputted from the detection winding as a result of an excitation signal inputted to the excitation winding. The excitation winding and/or the detection winding are composed of a combination of one or more sheet coils having one or more bore portions. The sheet coils are arranged at prescribed intervals in the lengthwise direction of a magnetic core to which the sheet coils are attached. A plurality of coil-storing grooves formed in a direction perpendicular to the lengthwise direction are provided in the core surface of the magnetic core. The coil portions of at least two portions of the respective sheet coils are accommodated in the coil-storing grooves.

摘要： A capacitive pressure sensor (1) using mutual capacitance type is provided. The capacitive pressure sensor (1) comprises a dielectric layer (2), a ground electrode (3), transmission electrodes (4), reception electrodes (5) and a controller (6). The transmission electrodes and reception electrodes have a matrix structure (FIG. 3). An electric field is generated between the transmission electrodes and the reception electrodes by the controller. When the dielectric layer is deformed by a pressure applied to the ground electrode, a capacitance of the dielectric layer changes. The controller detects the unit detection area (10) where the capacitance changes and the pressure corresponding to the change in the capacitance.

摘要： An objective of the present invention is to eliminate unnatural behaviors of a wireless controlled airplane during PID control. In a wireless controlled airplane, a receiving section receives a first operation signal for a first actuator, a second operation signal for a second actuator, and a third operation signal for a third actuator, wherein the first, second and third operation signals are provided as operation signals wirelessly transmitted. A first actuator control section is configured to generate an actuation signal for the first actuator by means of PID control depending on the first operation signal, and to reduce an integral element in the PID control depending on an operation value for the second or third operation signal. Alternatively, the first actuator control section is configured to perform switching to a control without an integral element from the PID control.
