摘要： An ultrasonic motor has a longitudinal-torsional composite transducer, a stator constituted by an ultrasonic vibrator sandwiching the transducer, and a rotor urged against the stator. The stator excites longitudinal-torsional ultrasonic vibrations to rotate the rotor by a frictional force. The motor includes a vibration adjusting rod for matching resonance frequencies of longitudinal and torsional ultrasonic vibrations of the stator with each other.

摘要： This invention provides an ultrasonic motor using a bolt-tightened Langevin type torsional vibrator as a stator. The stator produces a vibrational energy to be converted into a rotational energy for a rotor contacted with the stator. The rotor is provided between a piezoelectric actuator and the torsional vibrator so that the contact state between the rotor and the torsional vibrator is controlled either one of loose contact and tight contact therebetween. According to the present invention, since the piezoelectric actuator is slidingly combined to the rotor, the rotation energy is not applied to the piezoelectric actuator and thus the life time of the actuator becomes long.

摘要： In an electrostriction transducer comprising protection layers (21, 22) in which no electric fields are produced during operation, each of end electrostriction layers (41, 42) which are contiguous to the respective protection layers with pertinent ones of internal electrodes (16, 17) interposed, is given a thicker thickness (at) as compared with other or intermediate electrostriction layers (23) to make the transducer have a long life and a high reliability. The intermediate electrostriction layers may have a common thickness (t). Alternatively, the intermediate electrostriction layers may have monotonously decreasing thicknesses when placed nearer to a plane which bisects a pile (19) of the electrostriction layers parallel to both end surfaces of the pile. When a pair of holding members for the transducer are used on both longitudinal ends, each protection layer is preferably received in an indent formed in the holding member. Alternatively, it is preferred that each holding member should comprise a metal plate contiguous to the protection layer and a metal band surrounding parts of the metal plate and the protection layer.

摘要： A multilayer electrostrictive element has electrostrictive sections (31) defined by internal electrodes (32) in a stack, with a peripheral surface which has a predetermined outline perpendicularly of an axis of the stack, each internal electrode with an outline which is approximately congruent with the predetermined outline (constant cross-section). In order that external electrodes (33, 34) may readily be connected to the internal electrodes grouped by twos, each internal electrode may have a peripheral end which is partly recessed from the predetermined outline, as in FIG. 8. Alternatively, the internal electrodes of each group may be connected together by a conductor rod which passes through the electrostrictive sections, preferably along their edges, contacting alternate electrodes. For a great number of internal electrodes, an element may be manufactured by laminating conductive-paste-printed green sheets transversely of the stack axis and then sintering the lamination. Each internal electrode may include a ceramic material, such as an electrostrictive material of the electrostrictive sections, another electrostrictive material of a lower sintering temperature, or glass.

摘要： Apparatus for X-ray analysis has a combination of a rotating target X-ray tube and a composite monochromator. The composite monochromator has a first and a second elliptic monochromators joined with each other side by side. Each of the elliptic monochromators has a first focal point at which an X-ray focal spot on a target of the X-ray tube is disposed. Each of the elliptic monochromators has a synthetic multilayered thin film whose d-spacing varies continuously along an elliptic-arc. The shortest distance between the X-ray focal spot and the composite monochromator is set to 40 to 100 mm. Under the shortest distance condition, the effective focal spot size on the target is set to 40 to 100 micrometers to obtain the maximum X-ray intensity on a sample to be analyzed.
