摘要： A synchronization method and apparatus in redundant time-division-multiple-access communication equipment, wherein the synchronization between an active circuit and a standby circuit is carried out using a frequency divided signal from the active transmission frame timing signal instead of using the transmission frame timing signal. At timings other than the output timing of the frequency divided signal, the standby transmission frame counter runs independently. Thus, failure of the active circuit has less effect on the standby circuit and switching between the active circuit and the standby circuit can be carried out smoothly.

摘要： On a substrate are configured piezoelectric elements composed of a mirror device, piezoelectric thin films, electrodes, and elastic members, and application of a voltage to the electrodes causes flexure deformation in the piezoelectric thin films, so that the mirror device is actuated. A plurality of the piezoelectric elements are arranged in parallel with a longitudinal direction thereof, and torsion springs are provided so as to extend in a direction orthogonal to the longitudinal direction and so as to hold the mirror device in connection with the substrate. The mirror device is connected to the piezoelectric elements through strain absorbers. In such a configuration, the torsion springs serve as a rotation axis, and the mirror device is inclined about the rotation axis.

摘要： A first reticle is located at an object position of a lens to be evaluated. The first reticle is formed with a first diffraction grating. A stage supports the first reticle. A coherent light source illuminates a whole region of the first diffraction grating. A spatial filter blocks a 0-order component of diffraction light from the first diffraction grating. A second reticle is located at an image position of the lens and is formed with a second diffraction grating. A stage moves the second reticle within a projection range of the lens. Interference fringes are formed on the second reticle by re-diffraction by the lens. Moire fringes are caused by the second diffraction grating and the interference fringes. The moire fringes are observed.

摘要： A position signal producing apparatus, for an apparatus for project-printing a pattern on a reticle onto a wafer through a project lens system with exposure light, for producing a position signal indicative of the position of the wafer is disclosed, wherein two different frequency components of alignment light whose frequencies are different from that of the exposure light are interfered with each other at a position alignment blank to form interference fringes having a given pitch. The interference fringes are projected onto a diffraction grating through an achromatizing optical system and the project lens system. Diffracted light returning from the diffraction grating is received by a photodetector which provides a light beat signal. A position deviation signal obtained by phase comparison of the light beat signal provides position alignment by controlling relative positions between the position alignment blank and the diffraction grating. Two light beams of the two different frequency components split by a polarized beam splitter are equalized in image converting condition, or image aspect, by a mirror, so that an accurate mixing of the two frequency components of light beams is performed at the position alignment blank.

摘要： In a mechanically scanned ultrasonic probe, an ultrasonic transducer is swingably mounted on a drive shaft which is given a swinging transversal movement and a reciprocating longitudinal movement. The transducer emits an acoustic beam which is steered in a raster format in response to the swing and reciprocating motions. Echos returning from objects contain diagnostic data of a three-dimensional space. All the components are encased in a toothbrush-like housing having a head portion, an intermediate portion and a hand-grip portion. The dual motions are provided by a drive mechanism accommodated in the hand-grip portion and the transducer is accommodated in the head portion. The drive shaft extends through the intermediate portion.

摘要： A surface acoustic wave actuator is disclosed which includes unidirectional interdigital transducers disposed on both sides of a vibrator and an electrical combiner. One of the unidirectional interdigital transducers and external power supply are connected to an input port, and the other unidirectional interdigital transducer is connected to an output port of the electrical combiner. The electrical combiner combines input energy from an external power supply and surface acoustic wave energy is electrically converted by one of the unidirectional interdigital transducers, and input to the other unidirectional interdigital transducer. Surface acoustic waves excited by the other unidirectional interdigital transducer propagates on a vibrator, and is input to the other unidirectional interdigital transducer again after passing one unidirectional interdigital transducer and the electrical combiner. A relative movement member is pressed against the vibrator for generating driving force via a friction force so that the relative movement member implements relative movement to the vibrator.

Consequently, a position measurement accuracy can be improved.
