    摘要: An elevator control apparatus has a converter for converting AC power to DC power, an inverter for converting the DC power resulting from the conversion by the converter into AC voltage of a variable voltage and a variable frequency so as to drive with the AC voltage an induction motor for vertically moving an elevator car, a current detector for detecting the current output by the inverter and for producing an output signal indicative of the detected current, a current command generating circuit for generating a current command value for the induction motor, and a control circuit for controlling the inverter on the basis of both the current command value from the current command generating circuit and the output signal from the current detector. The control apparatus includes a cancellation circuit for cancelling offset voltage by storing, when the inverter is stopped while the current command generating circuit keeps generating the current command value, the output signal of the current detector, and by adding, when the inverter is in operation, the stored output signal to the present output signal of the current detector.

    摘要: A memory has plural storage areas for storing performance data of plural music pieces. When the player has input desired performance data via an input device like a keyboard, the thus-input performance data are automatically stored into a first storage area of the memory. At the same time, a specific search is executed by the search section to examine whether or not performance data of a music piece corresponding to the input performance data are already stored in the memory. If a second storage area storing the performance data corresponding to the input performance data has been detected or searched out, a series of the performance data stored in the second storage area are sequentially read out for an automatic reproductive performance. If, on the other hand, such a second storage area has not been detected, writing of the input performance data into the first storage area is continued without such an automatic reproductive performance being executed. Therefore, it is sufficient for the player to perform an operation to input a part or whole part of the desired music piece. Then, in response to the player's input operation, music piece number selection and readout or write processes are automatically carried out in accordance with the result of the search by the search section.

    摘要: A miniature motor having a housing formed into a bottomed hollow cylindrical shape. The inner circumferential surface to which a pair of permanent magnets, which are rare-earth plastic magnets of an essentially C shape in cross section, are fixedly fitted. An end cap is fitted to an open end of the housing, and a rotor is rotatably supported in the housing by bearings provided on the housing and the end cap. A pair of the permanent magnets are formed in such a manner that the magnetic force of each magnet is made different from each other so that the rotor can be attracted to the permanent magnet having a larger magnetic force. One of the permanent magnets is made of a rare-earth plastic magnet containing a coloring material.

    摘要: An automatic accompaniment apparatus for an electronic musical instrument is provided with an instrumentation selecting switch for selecting a desired instrumentation, a data generator for generating instrumentation data selected by the selecting switch when the selecting switch is depressed, and an accompaniment tone generator for generating an accompaniment tone signal in accordance with one of the number of tones corresponding to the number of musical instruments and a tone color corresponding to a tone color name of each musical instrument set in response to the instrumentation data derived from the data generator. Thus, when the desired instrumentation is selected by the selecting switch, the automatic accompaniment apparatus generates automatically the accompaniment tone signal with the number of tones and/or tone colors corresponding to the contents of the selected instrumentation. Further, the automatic accompaniment apparatus can also generate an accompaniment tone signal, for every instrumentation, with an accompaniment pattern suitable for the instrumentation.
