Title: Ultrasonic body detector
Inventor: YAMANE TOSHIKI
IPC: G01S15/04
Filed: 1986-06-25
Abstract: PURPOSE:To eliminate erroneous detection generated by the ultrasonic pulse from a separate ultrasonic body detector, by again transmitting the ultrasonic pulse of which the frequency is changed when the reflected wave from a body is received. CONSTITUTION:An ultrasonic pulse is transmitted from an ultrasonic sensor 1 and the reflected wave from the body 8 in a detection area is received by a sensor 1 to store receiving wave output in a memory part 22. A judge part 23 judges the presence of the body 8 from the wave form of the receiving wave stored. When the ultrasonic pulse signal from a separate ultrasonic body detector is received other than the ultrasonic pulse transmitted itself, the judge part 23 erroneously judges that two bodies 8 are present. Then, a transmitting-receiving frequency control part 25 controls a transmission pulse control part 21 to transmit an ultrasonic pulse with frequency different from that of the ultrasonic pulse previously transmitted from the sensor 1 and, at the same time, the center frequency of BPF of a receiving circuit 4 is altered. The judge part 23 receives the reflected wave from the body 8 to calculate the distance up to the body 8 and, when said distance coincides with the distance previously detected, the presence of the body 8 is detected for the first time to eliminate erroneous detection.

Filed: 1986-06-24
Abstract: PURPOSE:To suppress torque variation at control mode switching time, by a method wherein the magnitude of allowable variation rate of command signal is switched between at the control mode switching time and after switching. CONSTITUTION:Contact e is inserted to output side of a current command device 14 and closed at current control mode time, and contact e' is inserted to output side of a speed control device 12 and closed at speed control mode time. If control mode is switched by automatic speed control ASR/automatic current control ACR switching signal Z, a one-shot multivibrator 19 generates pulses of a definite time width T in synchronization with rise of the ASR/ACR changing signal Z, and contact f is opened and contact f' is closed while pulses are being generated thereby a current variation rate control device 16 is coupled. Since the current variation rate control device 16 reduces variation rate of the input signal, torque variation of a DC motor 1 at switching time can be suppressed.

Title: Automatic gain adjusting circuit and its method
Inventor: KIN KIHAN
IPC: H04N5/52
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To always maintain a constant level by using a mean amplitude value of receiving signal amplitude and a segment synchronizing signal and correcting receiving signal amplitude that is changed by a transmitting channel environment. SOLUTION: When an HDTV signal that is inputted in a tuner/IF demodulator and a segment synchronizing signal that is included in the HDTV signal are respectively larger than a 1st reference value which is set in an asynchronous AGC signal generating part 210 and a 2nd reference value which is set in a synchronous AGC signal generating part 220, the outputs of 1st and 2nd subtracters 213 and 224 become negative values and reduce the amplitude of the inputted signal. Also, when an inputted HDTV signal and a segment synchronizing signal which is included in the HDTV signal are respectively smaller than a 1st reference value which is set in the part 210 and a 2nd reference value which is set in the part 220, the outputs of the subtracters 213 and 224 become positive values and increase the amplitude of the inputted signal.  Therefore, even if input signal amplitude of the tuner/IF demodulator changes, the constant amplitude can always be maintained.

Title: Variable gain control circuit
Inventor: FUJII TOSHIKAZU
IPC: H03G1/04
Filed: 1988-06-17
Abstract: PURPOSE:To improve the noise distortion rate characteristic over a wide input signal range by applying full wave rectification to a collector current of a transistor(TR) pair and feeding back the result as a bias current of a control circuit. CONSTITUTION:Since collector currents of TRs Q3, Q4 are equal to each other, a current flows equally to TRs Q23, Q24. Since TRs Q21, Q22 constitute a full wave rectifier circuit, the bias current at no signal is minimized. With an input signal supplied, a differential output is obtained from the TRs Q3, Q4, but the output is subject to full wave rectification by the TRs Q21, Q22 and added to the original bias current. The added bias current results in increasing the operating current of the TRs Q3, Q4. Thus, a variable gain control circuit with a large S/N and a large dynamic range is obtained.

Abstract: PURPOSE:To set the height of a developing device low and to miniaturize the device by forming a guide means for carrying recording paper on the outer surface of the case of the developing device. CONSTITUTION:A guide plate 32, which guides the carrying of the recording paper, is integrally provided on the bottom part of the case 31 like plural fins. When the developing device 30 is attached to the specified position of an image output device main body, the guide plate 32 is opposed to a lower guide plate 35 and an upper intermediate roller 34 abuts on a lower intermediate roller 36 and forms a nip part. Then, the recording paper fed by a paper feeding roller 4 passes the nip part and is led to a resist roller 14 by the guide plate 32 and the lower guide plate 35. Since a developing case functions also as an upper guide plate, by such constitution, set space for the upper guide plate is omitted and the developing device is attached to a low position with respect to the lower guide plate 35, thereby miniaturizing the image output device main body.
