Title: Automatic gain control circuit
Inventor: NORO TOKUJI
IPC: H03G3/30
Filed: 1989-06-23
Abstract: PURPOSE:To prevent the gain from being maximized due to a rapid fluctuation of an input signal and to evade the interference onto other signals by applying on/off control to a power supply voltage to a differential amplifier depending whether or not the level of the input signal exceeds a prescribed value. CONSTITUTION:An input signal level of a variable gain amplifier 3 is detected by a detector 6 and a voltage comparator circuit compares 7 the level with a prescribed value. When the input signal level is smaller than the prescribed value, a controller 8 turns off the power supply voltage of a differential amplifier 5 to minimize the variable gain amplifier 3. On the other hand, when the input signal level is larger than the prescribed value, the controller 8 turns on the power supply voltage of the differential amplifier 5, the power supply voltage rises gradually based on the time constant of a time constant circuit 9 and the control voltage for the variable gain control rises gradually. Thus, an output signal level of the variable gain amplifier 3 is controlled stably even to a rapid level fluctuation of the input signal and the interference of the frequency to the adjacent channel signals in a radio communication equipment is prevented.

Title: Picture display device
Inventor: MATSUKI SHIGEYUKI
IPC: H04N7/08
Filed: 1988-06-30
Abstract: PURPOSE:To always continuously execute a display by outputting an internal synchronous signal generating circuit to generate a synchronous signal homogeneous with the synchronous signal obtained from a picture signal and, when the image-picked up picture signal is not obtained, the above-mentioned signal generating circuit as the synchronous signal. CONSTITUTION:The picture signal is supplied through a multiplexer 13 to the data terminal of a picture memory 14. On the other hand, the synchronous signal outputted from an internal synchronization control circuit 5 is converted to an address signal by a picture memory address control circuit 15, and it is supplied to the address terminal of the picture memory 14. Since the synchronous signal is not obtained from the picture signal when a camera 1 is removed, an internal synchronous signal generating circuit 21 for generating the synchronous signal cannot generate the synchronous signal by the internal synchronization control circuit 5. For such a reason, a switch 4 is changed over to the internal synchronous signal generating circuit 21 side, and by using the synchronous signal generated there, the action can be continued.

Title: Ic card
Inventor: YAMAGUCHI ATSUO
IPC: B42D15/10
Filed: 1988-06-30
Abstract: PURPOSE:To improve the safety of an IC card by disconnecting the 1st memory from a bus when a detecting means detects the execution of an application program by means of a CPU. CONSTITUTION:Since the program is shifted from a branched routine to an application program in an application ROM 4 when no product test executing command is inputted, a CPU 1 reads out the execution starting address of the application program previously stored at a prescribed address of the ROM 4 through a bus 2. When the CPU 1 reads out the address, a detection circuit 9 detects that the CPU 1 reads out the execution starting address of the application program and outputs a system ROM selection inhibit signals to a selection circuit 8. Upon receiving the inhibit signal, the selection circuit 8 stops to select a system ROM 3 irrespective of the state of the bus 2. Therefore, illegal access can be prevented.

Title: Howling suppressing method
Inventor: TSUBAKI KAZUHISA
IPC: H04R3/02
Filed: 1986-07-10
Abstract: PURPOSE:To correct an amplitude characteristic in a transmission function between a speaker and a microphone and to suitably suppress a howling by considering a frequency in which an increasing ratio higher than the average increasing ratio of all spectra is continued as a howling generating frequency and lowering the gain of the frequency. CONSTITUTION:The sound receiving signal of the microphone 10 is converted into the scale of the respective spectra Fi(i = 1-N) by an FFT circuit 11. In a howling detection circuit 12, the increasing ratio from the preceding spectrum of the respective spectra Fi is examined to obtain the average increasing ratio of all the spectra. Then, the increasing ratio of the respective spectra is compared with the average increasing ratio to detect the spectrum in which the average conciderably exceeds a certain level, if the state continues M times, it is decided that the howling is produced in the frequency and an equalizer is automatically adjusted so as to lower the gain in the frequency. Thereby, the change in the transfer function circulating from the speaker to the microphone can be followed and the howling can be suitably suppressed.
