摘要:
An automatic music performing apparatus comprises a performance memory for storing music performance data of a relative time format including an event group including at least note-on events indicating the note generation start, note-off events indicating the end of the note generation, volume events indicating the volumes of the tone, and tone color events indicating the tone color with the respective events arranged in a music proceeding sequence, and an interval of time interposed between respective two events, wherein the apparatus sequentially reads out the stored music performance data, converts it into note data representing the note generation properties of each note, and stores the note data in a conversion data memory, so that automatic music performance is executed by reading out the stored note data and forming tones corresponding to the note generation properties represented by the read note data.

A document data filing apparatus automatically selects attribute values indicating visual features of a desired document from the code data of document data inputted. The attribute value generation unit generates attribute values indicating visual features of the document data inputted as coded data from the document data input unit. At this point, the presence or absence of dot data and specific words and characters are judged. The document data storage unit stores the document data in association with its attribute for retrieval. The attribute value designation unit makes an operator designate the attribute value as retrieval key to the document data to be retrieved The readout unit reads the document data corresponding to the designated attribute value from the document data storage unit. The display unit displays the document data. The retrieving technique is applied to a word processor.

A recording and reproducing apparatus of the present invention has a magnetic head used for both recording and reproduction. To perform the changeover between recording and reproduction in a short period of time, a first recording amplifier for supplying a recording signal is provided at one end of the magnetic head, a second recording amplifier for supplying a recording signal of a phase opposite to that of the recording signal supplied to the one end of the magnetic head is provided at the other end of the magnetic head, and a reproduction input amplifier connected to the both ends of the magnetic head is provided. The same bias voltages are supplied through first and second resistors connected to the both ends of the magnetic head.

When a handwritten character is inputted with a pen of a pen input device, a handwritten character recognition unit recognizes the character according to coordinate data of the character. Also, a handwritten area judge unit judges the size of the character and a blank area according to a range of preset areas passed though the handwriting. A character font determination unit detects a character font from a plurality of character fonts to correspond to the character size judged by the handwritten area judge unit. The determined character font is outputted to a display device and the like.

A print control apparatus for use with a printer for forming a print output based on command data generated by a computer. The print control apparatus includes a line segment data conversion unit for converting computer-generated command data to successive pieces of line segment data each having a position and a length in a raster direction, and a raster image data conversion unit for converting the line segment data to raster image data based on which printing is performed by the printer.

In an optical fiber coupler there is provided, in an optical coupling portion between cores of two partly fused together and extended optical fiber, an optical coupling control portion which has a refractive index different from those of claddings covering the cores.
摘要:
Two single mode optical fibers are reduced in diameter over a predetermined length to form reduced-diameter portions whose center portions have different diameters. The two optical fibers are intersected at a small angle to each other substantially centrally of their reduced-diameter portions and then are fused together at the intersecting portions and the fused portions of the two optical fibers are heated and stretched to provide an optical coupler having a desired coupling ratio.

A tube protecting device comprising: a clamp support having first and second end portions and at least one clamp element attached thereto, the first end portion being bent to protrude away from the remainder of the clamp support; tube protecting means having a spring portion, a recess portion and an engageable end portion, the spring portion biasing the first end portion of the clamp support into engagement with the recess, the second end portion of the clamp support engaging the engageable end portion of the tube protecting means.
摘要:
External sound signal coupled through a MIC IN terminal is fed through an operating switch panel section to an A/D converter for conversion to a digital signal. The digital signal is stored in a record memory through a waveform R/W controller under the control of a CPU. The digital signal stored in the record memory is read out from the CPU according to control data stored in a work memory to be fed to an external sound system for sounding.
