    摘要: A feed guide mechanism for guiding a reciprocating movable member with a guide member having tabular elastic members forming a guide surface for guiding the reciprocal movement of the movable member on one surface thereof. A piezoelectric member with alternately polarized portions are attached to an opposite surface of the guide member. The piezoelectric member undergoes a polarization so that application of an alternating current produces a standing wave to urge the movable member upward and reduce friction.

    摘要: An automatic music transcription method and system for generating a muscial score from an input acoustic signal. The acoustic signal may include vocal songs, vocal humming, and music from musical instruments. The system comprises means for extracting pitch information and power information from the input acoustic signal, for correcting the pitch information based on the deviation of the acoustic signal relative to an absolute musical scale, for dividing the acoustic signal into a set of single-sound segments using the corrected pitch information, dividing the acoustic signal into a second set of single-sound segments this time using changes in the power information, for dividing the acoustic signal in still greater detail using information contained in both previous segmentations, for associating each segment with a musical interval of an absolute musical scale, and for determining single-sounds segments depending on whether or not the musical intervals of adjacent segments are identical, for determining the key of the acoustic signal, for correcting the placement of the segments on the musical scale of the determined key using the pitch information, for determining the time and tempo of the acoustic signal using this placement, and for compiling musical score data using the determined musical scale, sound length, key, time, and tempo of the acoustic signal.

    摘要: An arrangement for detecting movement in a picture displayed on a television display. Y/C color separation detects movement in a displayed picture by generating a first movement detection signal with respect to luminance, a second movement detection signal with respect to luminance and a movement detection signal with respect to color. The first movement detection signal with respect to luminance represents the difference between a luminance signal extracted by Y/C separation in a first frame and a luminance signal extracted by Y/C separation in a second, adjacent frame. The second movement detection signal serves as an auxiliary detection signal, and indicates any leaking of the color signal into the luminance signal after Y/C separation. The auxiliary signal, which indicates the leakage of any color signal into the luminance signal, is able to minimize erroneous detection of movement due to leakage of the color signal.

    摘要: A window system synchronizing protective circuit. A window forming circuit forming windows having a predetermined position which detect the forthcoming synchronizing signal in accordance with a counted value of bit clock pulses produced by a bit clock. The window forming circuit forms a corresponding number of windows to a predetermined number of bit clock pulses before and after detecting a synchronizing signal. The window forming circuit generates a window signal. A protective synchronizing circuit which has the detected synchronizing signal and the window signal generates a protective signal which has a phasic relation to the detected synchronizing signal. If no synchronizing signal has been detected in the windows the protective synchronizing signal is output. If the synchronizing signal has not been detected after a predetermined period a window reset circuit changes the position of the windows.

    摘要: A door operating mechanism for opening and closing a door with respect to a vertical opening of a case includes a hinge structure for selectively connecting an upper end of the door to the case in a hinged manner so as to guide a pivotal movement of the door between a vertically closed position and a horizontally extended open position where the door is extended outwardly from the case. There is provided a guide structure for guiding the horizontal movement of the door between the horizontal extended open position and a horizontal retracted open position where the door is received in the case. Thus, the door can be suitably received in the case, so that the opened door will not be obstructive.

    摘要: In a reproduction system for use in reproducing a still image from a sequence of predictive error signals which is read out of a memory and which is preliminarily processed into a sequence of preliminary processed signals, an intermediate circuit interrupts the preliminary processed signals in response to an external command signal. In the intermediate circuit, the external command signal is resampled by a sequence of frame pulses in a resampling circuit into a resampled signal so as to close a gate circuit. No predictive error signal is sent to an adder circuit during absence of the gate circuit. An identical error signal is repeatedly produced as a sequence of reproduced signals to reproduce the still image.
