Abstract:
A protective relay which hardly makes maloperation in itself regardless of mixing of low-order higher harmonics in its at least two sinusoidal input signals comprises a first and a second phase detection comparator generating two different-phase square signals indicative of the phase difference between the sinusoidal input signals, a first and a second timer receiving the square signals generated from the first and second phase detection comparators respectively and generating their output signals as a result of comparison between a first period of time and one of the periods or the period of presence or absence of the square signals, a third timer receiving the same square signal as that applied to the first timer and generating its output signal as a result of comparison between a second period of time and the other period or the period of absence or presence of the square signal, a fourth timer receiving the same square signal as that applied to the second timer and generating its output signal as a result of comparison between the second period of time and the other period or the period of absence or presence of the square signal, a first flip-flop set by the first timer and reset by the third timer, a second flip-flop set by the second timer and reset by the fourth timer, and a third flip-flop set and reset by an AND circuit and a NOR circuit respectively connected to the outputs of the first and second flip-flop.
Abstract:
Featured are methods for reconstruction of images acquired from any of a number of scanning devices or apparatuses known to those skilled in the art which methods are established so as to provide a mechanism for compensating for motion of an object being imaged. Such methods of the present invention are such as to allow the clinician to select one or more specific methodologies that is appropriate for the expected motion, severity or complexity of the motion and efficient processing of projection data. Also feature are systems, apparatuses, software code and computer readable media which embody such methodologies.
Abstract:
Analog signals are sampled and converted into digital data which is then filtered by a digital filter. The filtered digital data is then subjected to an arithmetic operation. The blocking band of the digital filter is set to a frequency band which is above the pass band of the analog signal components. Frequency of sampling, as well as the frequency of noise caused by the sampling, is elevated, so that the noise frequency falls within the blocking band of the digital filter.
Abstract:
In a transformer protection system, data of voltages and currents detected at individual terminals of a transformer connected to an electric power system are supplied to a computer. The computer computes driving point admittances or shunt admittances of the transformer on the basis of the voltage and current data and predetermined transfer admittances of the transformer and decides that an internal fault has occurred in the transformer when the values of the driving point admittances or shunt admittances deviate from pre-set reference values, thereby disconnecting the transformer from the electric power system.
Abstract:
The bioinstrumentation apparatus includes a light irradiation unit irradiating a measurement region with light, a light detection unit detecting diffused light from the measurement region, and a computing unit generating a reconstructed image for the interior of the measurement region. The computing unit calculates J coefficients wj set for every pixel of the reconstructed image and more than 0 and not more than 1 (where J is the number of pixels of the reconstructed image) and carries out successive approximation computation by the following iterative formula xj(k+1)=xj(k)+wjdj(k) (where k is an integer from 1 to N, N is the number of times of iterative computation, xj(k) is a pixel value of the jth pixel on the kth iterative computation, and dj(k) is an update amount of the jth pixel on the kth iterative computation) to generate the reconstructed image.

Abstract:
An information processing system comprises a plurality of systems (1, 3, 4, 6) communicating through a transmission path (2) and performing a processing base on their own function. One of the plurality of systems acts as as an supervising system having a supervising function. The supervising system (1, 4) sets a goal for each of the plurality of systems, collects the processing result on each system and evaluates the processing result; and on the basis of the processing result, the supervising system sets a new goal for each system considering a goal of the entire system comprising said plurality of systems.

Abstract:
The present invention is a processing unit for processing a substrate in a casing, having: a transfer port provided in the casing through which the substrate passes when the substrate is carried into the casing by a carrier for carrying the substrate; and an inflow restricting device for controlling an atmosphere outside the casing to restrict the atmosphere from flowing into the casing through the transfer port. According to the present invention, it is possible to control the atmosphere outside the casing to restrict the atmosphere from flowing into the casing, which restricts the temperature of the substrate in the processing unit from partially varying and the temperature distribution from becoming ununiform within a plane of the substrate.
Abstract:
An expert system in which a plurality of knowledge descriptive layers are provided in a flame system. Each descriptive layer is composed of several flames. The flames of the lower knowledge descriptive layer correspond to the elements of a knowledge processing object system. The content of frames of the upper knowledge descriptive layers is determined as an inference made with reference to the frames of the lower layer. This determination is initiated and executed when the content of slots of the flames is updated.
