摘要： Provided is a control apparatus and control method for a capacitive electromechanical transducer with small decrease in transmission/reception efficiency, and with sets of transmission/reception characteristics with different frequency ranges. The apparatus has cells each including first and second electrodes facing each other via a gap; includes a driving/detecting unit and an external stress applying unit. The driving/detecting unit performs at least one of causing the second electrode to vibrate and transmit elastic waves by generating an AC electrostatic attractive force between the electrodes, and detecting a change of capacity between the electrodes, the change being caused by the second electrode vibrating upon receipt of elastic waves. The external stress applying unit changes the external stress applied to the second electrode. The driving/detecting unit adjusts frequency characteristics by changing a parameter defining the frequency domain used in a transmitting/receiving operation, corresponding to the change of the external stress.

摘要： A sensor includes a movably supported movable element and an opposing member, and sensor detects a relative positional relationship between the movable element and the opposing member which are provided with a spacing therebetween. The opposing member has an impurity-doped portion which is provided at either an opposing portion, which is opposed to the movable element, or an adjoining portion, which adjoins the opposing portion. At least a part of the impurity-doped portion is formed on an opposite surface (that is, opposite to a surface that faces the movable element), from which opposite surface an electrical wiring is led out.

摘要： There is a case in which a generated acoustic wave is decreased owing to the attenuation of light, whereby a desired output is not obtained from an electromechanical transducer device that receives the acoustic wave. The control apparatus for controlling an electromechanical transducer device of the present invention includes: a conversion unit that converts a current output from a first electrode of the electromechanical transducer device to a voltage; a DC voltage applying unit that applies a DC voltage to a second electrode arranged with a gap between itself and the first electrode; and a generation unit that generates a control signal which makes at least one of the DC voltage and a conversion ratio for converting the current to the voltage be changed, on the basis of information about an elapsed time from a point in time at which an inspection object was irradiated with light.

摘要： An angular velocity sensor includes a supporting substrate, a detecting portion, a displacement detecting portion, a first driving portion, and a second driving portion. The detecting portion is supported by the supporting substrate movably in at least a free direction. The displacement detecting portion detects a displacement of the detecting portion in the free direction. The first driving portion excites a first reference oscillation of at least a portion of the detecting portion so that a first Coriolis' force in the free direction is generated in response to an angular velocity about a first axis. The second driving portion excites a second reference oscillation of at least a portion of the detecting portion so that a second Coriolis' force in the free direction is generated in response to an angular velocity about a second axis.

摘要： An optical deflector comprises a control means for controlling at least either a light source or a deflection means adapted to gauge the distance between the position of a deflected beam of light moving on a light receiving element in one direction and the position of another deflected beam of light moving on the light receiving element in the opposite direction and control the distance so as to make it agree with a predetermined value. Thus, the optical deflector can very accurately control the operation of the deflection means in such a way that it is not affected by changes of environmental temperature of the deflection means and the detection circuit, because a detection means for detecting the time when a beam of light passes by a predetermined angle of deflection of the deflection means is not used.
