Title: Howling preventing device
Inventor: UTSUNOMIYA KOICHI
IPC: H03G3/32
Filed: 1988-11-25
Abstract: PURPOSE:To prevent howling by applying frequency analysis to an input voice signal, detecting the frequency component consecutive for a prescribed time and suppressing and outputting it thereby detecting howling automatically and surely. CONSTITUTION:An input voice signal is subjected to A/D converter 13, the result is fed to a FET transformation 15 with a buffer memory 14 for a prescribed period altogether and a PSD arithmetic unit 16 obtains the square sum of the real part and the imaginary part. The output and a PSD smoothed output in the past in a memory 28 are multiplied by a multiplier 17 for each frequency component. Then the component being the result of multiplication is decided by a discriminator 18 depending on the threshold level and a coefficient pattern is prepared depending on the quantity and the exchanged frequency component is multiplied with the pattern at a multiplier 19 to obtain a frequency pattern in which the frequency component over a prescribed time or over is suppressed is obtained. The pattern is subjected to an inverse FET transform 20, and a voice signal from which an oscillated frequency component is eliminated from the input voice signal is obtained via a buffer memory 21, a D/A converter 22 and an LPF 23.

Title: Tone correcting circuit
Inventor: WATANABE TOSHIMITSU
IPC: H04N9/64
Filed: 1989-11-17
Abstract: PURPOSE:To correct the tone of a primary color by emitting the other primary color as well when reproducing the primary color by adding a primary color signal included in a signal, which is inputted to another driving circuit, to a signal to be inputted to a certain driving circuit with a prescribed ratio. CONSTITUTION:The fluorescent surfaces of projecting type cathode ray tubes 11-13 are composed of front glass panels, interference films and photophors bodies and an adder circuit 6 adds the blue primary color signal included in the signal, which is inputted to a driving circuit 10 for blue, to the signal including the green primary color signal to be inputted to a driving circuit 9 for green with the prescribed ratio. Thus, even when the tone of blue is changed by the interference film, the blue is emitted and simultaneously the green is emitted as well so that the chrominance value of the blue can be closed to the standard chrominance value of an NTSC. Then, the tone of the blue can be corrected.

Title: Controller for industrial robot
Inventor: KODAMA MITSUMASA
IPC: G05B19/21
Filed: 1985-12-28
Abstract: PURPOSE:To simplify the constitution and also to improve the reliability of a controller for industrial robot by using plural encoders, a holding brake, a brake releasing means, a static state detecting means, and a control means serving as a drive/stop means of a motor. CONSTITUTION:A CPU 10 forms a computer circuit together with a ROM 11, a RAM 12 and a keyboard 13 and performs various types of arithmetic such as the analysis of instruction, the calculation of the command value, the control of positions, etc. Furthermore the CPU 10 also serves as a brake releasing means, a static state detecting means, and a control means which drives and stops the servomotors M1-M6 and also sets the rotational directions of those motors. When a robot is controlled, the output of the CPU 10 is applied to the motors M1-M6 via servo amplifiers A1-A6. Then encoders E1-E6 detect the rotational angle of each motor and gives it to the CPU 10. Thus a holding brake 7 applies the damping force to the corresponding joint part based on a command of the CPU 10 and can also release said damping force. This simplifies the constitution of a controller for industrial robot together with improvement of reliability.

Title: Thin display device
Inventor: KONDO KENICHI
IPC: H04N5/66
Filed: 1987-11-27
Abstract: PURPOSE:To execute the gray scale display of a large liquid crystal by A/D- converting an analog voltage such as a video signal and inputting it to a driving circuit directly. CONSTITUTION:By utilizing an interface signal such as the video signal, a synchronizing signal, the gray scale display is executed on a thin display. Namely, when a horizontal synchronizing signal Hsyc is inputted, a PLL circuit 24 outputs a dot clock signal P1 synchronized with a video signal VD. The dot clock signal P1 is 1/2-frequency-divided by a flip-flop circuit 25. Since the sampling signal of an A/D converting circuit 28 is the dot clock signal P1, the analog voltage is outputted by being converted to the digital signal of 4 bits for 1 clock. The digital signal of 4 bits.parallel is inputted to latch circuits 29 and 30, and since the latch signals of the latch circuits 29 and 30 are 1/2- frequency-dividing outputs P2 and P3 of the flip-flop circuit 25, they are time- serially stored, and they are outputted to a latch circuit 31. Thus, the gray scale display of a large liquid crystal display can be executed.
