摘要： Bar code data are read out by a bar code reader from a medium on which predetermined tone data are printed in the form of bar codes and are successively stored in a RAM. When a mode selection switch is set to a position "NAVI", a LED provided in the vicinity of a performance key corresponding to the pitch of a tone next to be produced next, is turned on under the control of a control section. Performance of music can be obtained by successively operating performance keys indicated by associated LEDs turned on one after another.

摘要： Disclosed herein is a system including a first optical fiber transmission line, a plurality of second optical fiber transmission lines, a branching section for optically connecting these first and second optical fiber transmission lines, a monitor device optically connected to the first optical fiber transmission line, and a plurality of reflecting sections respectively provided in the vicinity of open ends of the second optical fiber transmission lines. The monitor device outputs monitor light through the first optical fiber transmission line and the branching section to each of the second optical fiber transmission lines. The reflecting sections reflect the monitor light to thereby generate identification optical signals having different patterns for respectively identifying the second optical fiber transmission lines. With this configuration, the monitor device can detect an abnormality in each of the second optical fiber transmission lines according to the presence of absence of the corresponding identification optical signal.

摘要： An optical network system for bidirectional transmission between a main system (e.g., central station) and a plurality of auxiliary systems (e.g., subscriber's stations). The main system outputs a main optical signal to a main fiber. The auxiliary systems output auxiliary optical signals to a plurality of auxiliary fibers, respectively. The main fiber and the auxiliary fibers are network-connected by a connecting unit. The main system has a detector for detecting the auxiliary optical signals and a control signal generator for generating a control signal including data for designating a specific auxiliary system whose auxiliary optical signal is not detected. The main optical signal in the auxiliary fiber corresponding to the specific auxiliary system is attenuated according to the control signal. Accordingly, laser hazard in each auxiliary system is prevented.

摘要： An optical transmission device in which: a first cyclic filter with a fixed transmission wavelength characteristic and a second cyclic filter with a variable transmission wavelength characteristic are combined, and the transmission wavelength characteristic of the second cyclic filter is changed according to a target wavelength, to thereby control the relative phase relationship of the transmission wavelength characteristics of the first and second cyclic filters. Moreover a light source is controlled according to a monitored value of the transmittance of the second cyclic filter with respect to the control target light, to thereby match the wavelength of the control target light with the target wavelength. Consequently, it is possible, with a simple configuration using a combination of two cyclic filters, to variably control wavelength at arbitrary wavelength intervals at a high level of precision.

摘要： A step signal of which the period varies according to random data is derived from a step pulse generator, and is supplied to an address counter. By the output data from the address counter, an address of a waveform ROM is specified. From a waveform ROM, the waveform based on the random data is output in the form of a distorted waveform signal. Using this output signal of the distorted waveform, a cymbal sound, for example, is generated in a musical tone generator.
