摘要： A speed variable moving sidewalk for conveying passengers includes an endless circulating path having inverting sections, a high-speed section and speed variable sections, and a large number of treadboards moving along the circulating path. Each treadboard can move independently as being guided by guide rails and has hooks on its underside which engage shafts of a driving chain for inverting section. The treadboard further has hooks on its underside which engage shafts of a rack chain in order to be driven in the high-speed section and a roller for transversely sliding relative to the neighboring treadboard. A handrail mechanism for the speed variable moving sidewalk includes: with the total length of the moving sidewalk being divided into plural portions, a multiple-number of independent moving handrail portions for allowing passengers to hold thereon, being arranged for the respective portions of the sidewalk while all of the moving handrail portions are arranged without overlapping with one another.

摘要： In an error detection and correction method, when decoding second codewords of doubly encoded information codes, the second codewords, which are considered to have a correlation with the occurrence of burst errors, are classified into groups on the basis of the decoding states of first codewords of the doubly encoded information codes, and the second codewords are decoded sequentially in the order of a group having lower error misdetection probability and on the basis of the decoding states of the second codewords, namely, the error occurrence states, up to that time, thereby enhancing the error detection capability.

摘要： An echo canceller includes means for reducing correlation in a receiving side input signal based on a linear prediction model by regarding the receiving side input signal as an output signal of the linear prediction model. This means for reducing correlation is provided in a form suitable for hardware implementation, and thus, a convergence rate for the receiving side input signal having strong correlation as a speech signal can be improved without substantially increasing the number of calculations or the amount of memory.

摘要： This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.

摘要： An ultrasound diagnostic apparatus includes a linear array of piezoelectric transducers or plates with a width-to-thickness ratio of less than 0.8 and a control circuit which includes a transmitter and a receiver. The transmitter comprises a plurality of transmitting channels each including a local oscillator for generating an ultrasonic pulse in response to a clock signal. The plurality of such ultrasonic pulses are applied through a switching network to a selected group of successively arranged piezoelectric transducers to transmit a beam of ultrasonic energy into a human body. Each of the ultrasonic pulses is phase shifted and amplitude modulated with respect to the ultrasonic pulses of the other transmitting channels to provide phase and amplitude taper which results in a narrow width beam through the depth of the body. The ultrasonic energy returned from discontinuities between different tissues is detected by the activated transducers and applied through the switching network to the receiver in which each of the return signals is phase shifted and amplitude modulated with respect to the other signals to provide an output signal which is displayed on a cathode ray tube screen.
