Title: Motor speed controller
Inventor: MAITA TETSUYA
IPC: H02P5/50
Filed: 1992-04-13
Abstract: PURPOSE:To prevent imbalance of load from occurring between a main motor and a helper motor provided with drooping characteristics at the time of speed regulation control. CONSTITUTION:When a speed reference signal REF is increased, a current control signal I1 outputted from a main motor side speed control circuit 12 increases thus accelerating a main motor 6. A helper motor side speed control circuit 18 also begins to increase the output thereof, i.e., a current control signal I2, but the level of the signal I2 is confined within a range of upper limit UL and lower limit LL by means of a control output limit circuit 22. The limit values UL, LL are set in reference to the signal I1 by means of an upper/lower limit setting circuit 21. When the range of the signal I2 is limited by the circuit 22, feedback amount to be inputted to the circuit 18 side through a drooping amount setter 1 decreases and thereby output of the signal I2 can be increased. Consequently, the helper motor 7 having drooping characteristics can be accelerated while keeping balance with the main motor 6 side.

Filed: 1985-04-30
Abstract: PURPOSE:To estimate an accurate process characteristic where a delay time is taken into consideration, by adding an identification signal to an adjustment output to obtain the response delay time of a process and estimating the process characteristic on a basis of the adjustment output and the process response output. CONSTITUTION:The deviation of a response output PV of a process 2 from a target value SV is obtained by an adding part 11 and is given to a PID operating means 12. The means 12 uses a PID parameter obtained by a PID parameter determining means 17 to operate this deviation and gives an adjustment output MV to an additing part 13. The adding part 13 gives the result of addition between the output of the means 12 and the identification signal from an identification signal generating means 14 to the process 2. A delay time TL from the time, when the identification signal is given, to the time when the response output PV of the process 2 is varied is measured by a delay time measuring means 15 and is given to a process transfer function operating means 16. After measuring the time TL, the means 16 calculates a process transfer function and gives it to the means 17. The means 17 uses this transfer function to determine an optimum PID parameter and gives it to the means 12.

Title: Binarization device
Inventor: WADA YOSHIHIRO
IPC: H04N1/403
Filed: 1987-04-17
Abstract: PURPOSE:To prevent the deterioration in the quality of a read picture by using a binarized threshold value set by a picture density so as to binarize the output signal, counting it and discriminating the adequacy of the threshold value so as to control the threshold value. CONSTITUTION:An input picture signal 6 is compared with a slice level (threshold value) 7 by a comparator 1 and outputs a binarized signal 8. A binary signal counter 2 counts a count number 9 and inputs it to comparators 3, 4. The comparators 3, 4 compare the proper counts C1, C2 (C1<C2) with the count 9, the comparator 3 outputs a signal X1 when the count 9 is larger than the proper count C1 and the comparator 4 outputs a signal X2 when the count 9 is smaller than the proper count C2. With the signals X1, X2 at an H level, an AND 5 outputs a picture density proper signal. When no output is obtained from the AND 5, the slice level 7 is controlled. Thus, white or black level packing of the picture is prevented and the deterioration of picture is prevented.

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To enable data to be printed along a ruled line on a recording medium in a manual printing device. SOLUTION: This manual recording device corrects printout data to a recording head 5 based on a detection signal generated by a sensor 27 for detecting a ruled line, and performs a printing job at a position corresponding to a ruled line position. However, in order to deal with such a trouble that a shift from the position of the printing device for the ruled line is significant and therefore, this correction is not effective enough to solve the shift problem, the drive of an upper and a lower motor 16b, 16a connected to an upper and lower roller for the travelling of the printing device has to be controlled before the trouble occurs. Thus the travelling direction of the device is automatically modified.

Title: Flutter eliminating method at multiple magnetic record data reproduction time via frequency modulation of in strumentation signal
Inventor: IKEUCHI KOUTAKA
IPC: G11B20/02
Filed: 1978-07-31
Abstract: PURPOSE: To enhance S/N eliminating the flutter signal from each instrumentation signal after demodulation.  
     CONSTITUTION: The frequency modulation is given to instrumentation signals IaWIn via frequency modulators 2aW2n, and the modulated instrumentation signals are multi-transmitted along with the carrier of frequency converter 3 which transmits only the fixed carrier to be multi-recorded in the magnetic tape. Then this magnetic tape is reproduced, and the reproduced signal is demodulated through demodulator 5. Thus the flutter signal of magnetic tape recorder 4 as well as each of signals IaWIn are obtained. Then the subtraction is given to the flutter signal as well as each of signals IaWIn containing the flutter signal via instrument 6. As a result, signals IaWIn containing no flutter signals are  obtained at the output side of instrument 6. Accordingly, the S/N can be enhanced, ensuring a high- accuracy process for the instrumentation data via the computer.

Filed: 1995-04-19
Abstract: PURPOSE: To silence a noise tone when a carrier is interrupted attended with speech termination by interrupting a tone signal at the end of speech, allowing a terminal equipment of an opposite party to detect it and to interrupt a channel and then interrupting the carrier. CONSTITUTION: A terminal equipment is provided with a tone signal generating section 17 and a tone signal detection section, a reception side of the terminal equipment is provided with a tone squelch 10 using a tone signal with a tone signal frequency and the tone squelch interrupts a channel prior to the processing of a noise squelch 7. When a called party hooks off, a tone signal is sent and the caller detects the tone signal to allow the caller to detect hook- off of the called party. Furthermore, at the end of speech, the tone signal is interrupted before the carrier sent by the terminal equipment hooking off its handset earlier is interrupted, and the opposite party interrupts its own channel through non-detection of the tone signal by the interruption of the tone signal. Thus, the noise generated when the carrier is interrupted later is not heard by a receiver.
