Title: Keyboard
Inventor: NAKAMURA HIROSHI
IPC: G06F3/023
Filed: 1985-08-21
Abstract: PURPOSE:To allow one keyboard to ensure a variety of key operations regarding a character array by executing a display corresponding to keys in a character array by means of a logic circuit in a keyboard or through control of CPU with the aid of the signal of a mode selection switch installed on the keyboard. CONSTITUTION:In correspondence to the mode selected through the mode selection switch 2, a mode signal is transmitted to a display controller 4 and a code conversion logic circuit 6. The former 4 transmits and displays a key code corresponding to the mode of each key included in a key group 3. When it key-operates, a code converting logic circuit 7 converts a character code and a symbol code into codes corresponding to a character and inputs them to the CPU. Modes in a character array can be increased by extending the code converting logic circuit 7. Since any character array can be possible for the keyboard unit without affecting the CPU, a mode suitable to individuals can be used.

Inventor: OZAWA TORU
IPC: G10K9/12
Filed: 1988-07-22
Abstract: PURPOSE:To easily change sound pressure of a piezoelectric buzzer by varying a voltage applied to an oscillation circuit. CONSTITUTION:When a piezoelectric buzzer 10 is sounded by lowering sound pressure under the control of a microcomputer 6, an output of a pulse signal output terminal 7, namely, a voltage waveform Va becomes a pulse signal whose duty is about 50% as shown by (a) in the figure. When Va is V+, a capacitor 3 is charged through a base resistance 5, and when Va is '0'V, the charge is discharged through a resistance 4. As a result, a base voltage waveform Vb of a transistor 2 becomes a DC voltage containing a ripple. To an emitter of the transistor 2, a piezoelectric buzzer oscillating circuit 9 is connected, and it becomes a circuit of an emitter follower 7, therefore, when a digital output of a piezoelectric buzzer sounding control terminal 8 becomes a Low level (0V), a voltage which has subtracted a base emitter voltage of the transistor 2 from a voltage of (c) in the figure is applied to the piezoelectric buzzer oscillation circuit 9.

Filed: 1982-10-19
Abstract: PURPOSE:To prevent distortion of a sound output due to dropout with a simple constitution by muting a reproduced output signal if a prescribed amount or more of dropout of the reproducing signal occurs at a prescribed time. CONSTITUTION:When lots of dropouts occur continuously in a detecting circuit 55, a multivibrator 73 is inverted, switches 53L, 53R are turned off for a prescribed time and the sound reproducing output signal is muted. A demodulating sound signal is extracted in this way. If lots of dropouts take place continuously, a signal havng distorted waveform is not outputted because of holding of pre-stage circuits, because the output signal is muted. Thus, the distortion of sound output due to dropout is prevented with a simple constitution.
