    Abstract: An optical head system designed to accomplish an information recording and/or reproduction from opposite disc surfaces of an optical disc with the use of a single light source. The optical head system comprises a source of light for providing a linearly polarized beam of light; a collimator lens for collimating the linearly polarized beam of light into a collimated beam of light; a polarizing direction rotating unit for arbitrarily varying a direction of linear polarization of said beam of light; a polarizing beam splitter for dividing the beam, whose direction of linear polarization has been varied, into first and second beam components; and objective lenses for focusing the first and second beam components into respective penciles of light which are projected onto first and second, opposite disc surfaces of an optical disc or one disc surfaces of respective first and second optical discs.

    Abstract: A performance apparatus for producing a mixed musical tone signal having a comparator and a modulator. The comparator detects key data corresponding to musical tones having the same pitch and the same or similar tone colors from key data of musical tones to be mixed. The modulator changes at least a tone element of the mixed musical tone signal on the basis of the key data detected by the comparator to produce tones having multiple-tone like tone colors. The modulator comprises a detuner for detuning pitches of some musical tones of a plurality of musical tones formed based on the key data detected by the comparator, or comprises a modulator for modulating an amplitude or a frequency of the musical tone signal formed and mixed bases on the key data detected by the comparator.

    Abstract: An automatic performance apparatus provides a memory capable of storing plural parts of a desirable tune, wherein each part can be independently recorded or reproduced, regardless of recording or reproduction of another part. While performance information of one part is recorded or reproduced after a first detector detects the designation of recording or reproducing of one part so that an automatic performance of one part is played, the automatic performance apparatus can reproduce another performance information of another part after a second detector detects a section end of one part so that another automatic performance of another part is played. This another part is started to be automatically performed at the timing synchronizing with a progress of recording or reproducing the performance information of one part. Thus, the synchronization between one part and another part can be automatically obtained without effort.

    Abstract: An optical head in which the light emitted from a light source is narrowed to a minute spot of light and applied to a recording medium such as a disk thereby to effect recording and reproduction, or reproduction alone. A focusing plate or prism is provided in the optical path for forming the image of the light reflected from the recording medium. The focusing plate or prism has a first surface which reflects and transmits the reflected light and a second surface which is located closer to the image-forming position than the first surface and reflects the reflected light which is transmitted or reflected by the first surface. The optical head is further provided with a photodetector which is divided into at least two portions which individually receive the light rays which are respectively reflected from the first and second surfaces. A focusing servo control signal is obtained from the difference between the respective outputs of the divided photodetector portions. Moreover, a tracking servo control signal is obtained from the difference between the respective outputs of the peripheral portions among the divided photodetector portions.

    Abstract: An electronic control fuel injection system for a spark ignition internal combustion engine is described wherein air flow rate is controlled as a function of fuel flow rate by transmitting an operator's depression stroke of an accelerator pedal to a fuel selecting mechanism, applying a signal representative of the selected fuel flow rate to a computer which determines the optimum air flow rate, thereby controlling the opening of a throttle valve to provide it. Within the computer, the relationship of the accelerator pedal movement to actual fuel flow command is varied in a predetermined manner to provide a desired engine response characteristic. Thus, the drive feeling for a vehicle can be varied within a range from normal to either a faster or more conservative engine reaction.
