    摘要： An electronic device having operating buttons is provided. The operating buttons can be identified only by touching on the operating button even under a condition being incapable of visually recognizing such as a case of operating the operating buttons by a visual handicapped person, a case of operating the operating buttons in a dark place, or the like. In the electronic device having operating buttons for operating the device by closing and opening a switch with a pushing action, the operating buttons are provided in an operating surface of the buttons, and each of the buttons comprises at least one projecting portion or uneven portion which has a dimension equivalent to resolution of a human fingertip.

    摘要： A system and method for synthesizing musical melodies on a computer displays a plurality of figures on a display device, one or more of which can be selected by a user for conversion into a series of sounds to create a melody to be played through an electronic musical instrument. In operation, various sub-routines stored within a system processor are used to manipulate attributes such as position, shape, color, and size of the displayed figures to generate corresponding sounds having a desired pitch, intensity, timbre, and sound length. The displayed figures are then made to move in accordance with user-selected rules, or with melodies played on an electronic musical instrument. An octave filter or wide range filter may be employed to change other attributes of the individual sounds comprising the melody, or of the entire melody itself.

    摘要： To provide an optical disk recorder capable of reading data currently recorded even if the power supply is turned off during the recording of record data in a system using an optical disk in which table-of-contents information is not recorded in an area other than a user's recording area for recording record data and recording and reproducing of data is controlled according to the table-of-contents information. The optical disk recorder comprises an optical disk constituted so that table-of-contents information is written in an area other than a user's recording area for recording record data, a storage circuit constituted so that data can be read out of or written into the circuit by extending or compressing regenerated or recorded data in order to reproduce or record data from or into the optical disk, and a system controller for controlling reproducing and/or recording of data from and/or into the optical disk and storage circuit, and writes table-of-contents information in an area other than the user's recording area of the optical disk in accordance with a decided command for deciding the table-of-contents information given to the system controller, while recording record data in the user's recording area of the optical disk.

    摘要： A system and method for the conversion of digital signals to analog signals increases the resolution of the output analog signal beyond the analog quantization size associated with the given input digital word length. The rate of change of the Least Significant Bits (LSB)is detected. The "square waves" produced by changes in the polarity of the LSB correspond to low amplitude signals comprising audible high frequency components. The high frequency noise associated with these detected low signal levels is attenuated by digital low pass filters of varying cut-off frequencies at the output stage. This creates a signal of a resolution higher than the step size inherent in the length of the input digital word, and reduces high frequency noise at low signal amplitudes, resulting in a smooth analog output signal.

    摘要： Disc playback apparatus is provided with a rotatable carousel carrying a plurality of discs. The carousel is stopped so that a disc to be selected arrives at a predetermined position where it is removed and transferred to the playback apparatus and vice-versa. The carousel has a disc-shaped base and a plurality of disc clampers located on the base in a radial direction. Each of the clampers are formed of a disc support and a clamper member supported by a bearing provided on said disc support and have a convex portion adapted to engage with the bore of said disc. A spring member biases the convex portion of the clamper member so that the disc is held against the disc support and is selectively disengageable against the bias of said spring member so that it may be released from said carousel for transfer to said disc playback apparatus by said transfer means.
