| 20100101336 | MAGNETOSTRICTIVE TORQUE SENSOR AND TORQUE DETECTION METHOD - A magnetostrictive torque sensor that detects a torque of a rotating shaft and/or a stationary shaft by using a magnetostriction inverse effect that occurs on a shaft surface, the magnetostrictive torque sensor includes a first detection coil, a second detection coil, a first oscillation circuit, a second oscillation circuit, a first direction magnetic permeability detector, a second direction magnetic permeability detector, and a torque detector. | 04-29-2010 |
| 20090051355 | Proximity sensor and proximity detection method - A proximity sensor for detecting proximity of a metal, wherein a driving signal is output to a resonant circuit that includes a capacitor connected to a detecting coil, and the proximity of the metal is detected based on a phase shift of freely oscillating waves that are attenuatedly output from the resonant circuit after an output of the driving signal is stopped, the proximity sensor includes a controller that outputs the driving signal to the resonant circuit; and measures a phase shift of oscillating waves that is involved in the proximity of the metal based on the freely oscillating waves that are attenuatedly output from the resonant circuit after the output of the driving signal is stopped. | 02-26-2009 |
