摘要： The acceleration/deceleration control apparatus using slip speed detects an angular frequency .omega.r corresponding to an execution speed of an induction motor and derives an angular frequency .omega.s corresponding to a slip speed corresponding to a slip speed in response to a torque of the said motor, from a vector controller of the said motor.On the other hand, an allowable value .omega.s' of said angular frequency corresponding to the said .omega.r is prepared beforehand, and is compared with said angular frequency .omega.s.According to the result of this comparison, the IM rotation is controlled. So even if the induction motor is used as servo motor, no shock of the torque will flow through the motor and the motor itself will not be stalled.

摘要： A reference space includes a plurality of reference graphics. An image space is obtained by imaging the reference space. Affine transformation series are determined from the reference and image spaces for transcribing graphic cores of imaged graphics on graphic cores of reference graphics. If an affine-transformed positional error falls outside a tolerance, the reference space is divided into sub-spaces. Affine transformations and space divisions are repeated for out-of-tolerance sub-spaces until their estimations of distortion finally fall inside the tolerance.

摘要： A synchronous digital data processing system employing single-phase clock pulses comprises arithmetic and control units which are capable of completing an operation during one clock pulse period. The data processing system includes closed data paths wherein only one stage of a memory circuit capable of the same operation as a master/slave flip-flop is used as a data register in the arithmetic unit and as an address register in the control unit. In either case, during one cycle of a single-phase clock pulse, an input data is set in the memory circuit, and the output of the memory circuit is renewed in response to the input data. The output of the memory circuit is held until it is renewed in the following cycle.

摘要： A part of the output light from a semiconductor laser (1), which has a wavelength controllably variable with an injection current, is split at a beam splitter (3) and introduced into a interference optical system (5). In order to vary an optical path length difference between two light beams in the interference optical system (5) to modulate interference fringes to be obtained, AOMs (55, 56) are arranged on the two split optical paths and an EOM (56) on one of them. The interference fringes obtained from the interference optical system (5) are received at a photoreceptive device (7), and from the received signal, the phase is detected by a phase detector (8) and the phase amplitude is detected by an amplitude extractor (9). In order to stabilize the wavelength, a controller (10) feedback controls the injection current to the semiconductor laser (1) so that the phase amplitude matches to a predetermined setting.

摘要： A phase delay correction system for use in a shape measurement is capable of removing the distortion of a restored shape and the mechanical positional deviation caused by a phase delay occurring during signal processing, and enables a Fourier series processing procedure to be adopted as is. A detector performs a relative scan of an object to be measured at a constant speed. A signal processing unit converts a shape detection signal obtained by the scan to digital data, and processes the digital data. The signal processing unit has a digital filter for removing a noise component, an LUT memory for storing correlation data representing a correlation between a spatial phase and an amount of phase delay measured in advance in an output of the filter a Fourier coefficient calculating section for calculating coefficients of a cosine component and a sine component of each spatial phase for expressing detection data obtained from the filter in a Fourier series, and a Fourier coefficient correction section for correcting each of the coefficients calculated by the calculating section, on the basis of the data read out from the LUT memory.

摘要： There is provided a length measuring machine which is not influenced by fluctuations of air or changes in temperature. At a structure, graduations are formed in a longitudinal direction, and further a built-in light wave interferometer is provided. The built-in light wave interferometer measures a length of the structure and supplies the data to a current controller. In order to reconcile a length of the structure with a nominal value, the current controller supplies current to an electrical resistor provided at the structure to cause thermal expansion of the structure, or the structure is cooled.
