摘要： PURPOSE:To facilitate the manual-automatic bumpless changeover and at the same time to avoid the reset wind-up, by performing control using a position type operation and changing the value of integral arithmetic term when an excessive error arises. CONSTITUTION:A processor 1 performs a PI function. A position type control output is calculated on the basis of a measured value Mn, set value SP, proportion gain Kp and input signals of integrating time and differentiating time, respectively. The control output is converted into an analog voltage and applied to a holding capacitor 6. Control is changed from a manual operation to an automatic operation by varying the voltage of the capacitor 6 via a switch 7. Then the integral constant term is set again based on the output of a PI limiter in case a large deviation continues for a long time in order to prevent the reset wind-up.

摘要： PURPOSE:To perform the operation efficiently with a simple constitution, by applying operation parameters to the setting circuit consisting of a DC power source and plural variable resistors analogically and by subjecting the result operated by a processor to A/D conversion and by sample-holding and outputting the A/D conversion result. CONSTITUTION:Operation parameter setting circuit 50 consisting of DC power source 51 and variable resistors 52-55 is provided to the outside of processor 20. The analogue signal is converted to a digital signal and is supplied to processor 20, and the operation is performed by CPU23, data memory part 22, ROM24, and so on. The operation result is sent to D/A converting device 30, and the analogue output of device 30 is led to analogue signal holding circuit 40 and is sample-held and is output from output terminal 45. As a result, various operation parameters are given analogically with the simple constitution, and they are prevented from being lost at a power failure time.

摘要： PURPOSE:To permit automatic typing and facilitate the typing, correction and elimination of similar sentences by successively storing in memory means the type position of the type chucked by the typing mechanism and the printing position on a typing paper. CONSTITUTION:With a lever 33 held by a hand, while a type board 3 is being moved in the X1 and Y1 directions, a specific character is selected, and a printing instruction switch 81 is depressed. Consequently, a signal is applied to a microprocessor 10 to actuate a motor 73 for a typing mechanism 7 to perform printing on a typing paper 51. The type position represented by X1 and Y1 of the type having printed is detected by motors 41 and 42 and stored in memory means 18 or 9. When the printing is finished, by the signal from the processor 10, a platen 5 moves by a given pitch, and said position signals X2 and Y2 are stored in the memory means 18. To effect correction, the platen 5 is moved to the position of the character necessary to correct by depressing switchs 83, and correction is instructed through function keys 85 to print a correct character thereon.

摘要： PURPOSE:To enable to make a word processor for common use as an input/output device, by securing an identical arrangement of characters for a typewriter to the arrangement of characters within a character generator. CONSTITUTION:When the characters are supplied from the typewriter 8, a head line guide is provided at the prescribed character position in the group of types. The position of this headline guide is converted into the vertical and horizontal position signals and then into the signal compounded by a demodulator within the typewriter 8 to be supplied into the document memory 3 for storage as the position of type. To deliver the output of the character code stored in the memory 3, the character output code is put into the typewriter 8 to be decomposed into the vertical and horizontal position signals in the group of types through a demodulator in the typewriter 8. Then the prescribed type is decided with a single meaning and then printed on the printing paper. At the same time, these signals are displayed on the display unit 6 via the character generator 5.

摘要： PURPOSE:To fully automate the selection of printing type, print pressure control, paper feed, etc., by inputting electric signals that correspond to characters. CONSTITUTION:Signals inputted to input terminal 1 are converted 2 into X-directional and Y-directional digital data, which are inputted to signal generators 3 and 4 respectively. The difference between the output of generator 3 and a signal from converter 11 is found and applied to servo amplifier 5, which drives servomoter 6. Servomoter 6 moves printing type group 20 in the X direction by the distance that corresponds to the output of generator 3. Converter 11 generates the digital signal that corresponds to the X-directional movement of printing type group 20 and this servosystem stops at the point in time when the output of converter 11 agree with that of generator 3. On the other hand, when the output of converter 12 agrees with that of generator 4, the servosystem stops and the Y-directional positioning ends. Controller 9 detects the dissidence between stop points of the servosystem in both directions to supply hammer 10 with a driver signal for driving the hammer.

摘要： PURPOSE:To prevent an automatic selective control system with several control variables and one operation terminal from being unstable due to chattering when a selected regulator is put in a stand-by state by switching. CONSTITUTION:In the regulator used for an automatic selective control system, the output of amplifier 5, process variables of measurement value Mn, set value Sp, bias value B..., and external feedback signal YF are inputted to analog comparators 21 to 28, where they are compared with the output voltage of DA converter 3 to convert each input voltage into a digital signal, and processor 1 receives respective digital signals and then computes position type control outputs on the basis of the input signals; and its output is converted by the DA converter into an analog voltage, which is led to hold capacitor 6 via semiconductor switch 4 before being supplied to an object to be controlled via amplifier 5. Although high selector SLC select a higher output between outputs (y1) and (y2) of two regulators CNT1 and CNT2, constant bias value B is added and subtracted to and from the highest limit and lowest limit, thereby preventing chattering.

摘要： PURPOSE:To ensure continuation of the output of the arithmetic result even after recovery of the power source by holding the arithmetic at the power interruption time, and thus to simplify the overall constitution as well as to realize the cost reduction. CONSTITUTION:The power source to actuate processor P2 is interrupted, so switch 51 of analog signal holding means 5 (comprising semiconductor switch 51, capacitor C52 and amplifier 53) is turned off. As a result, the arithmetic result which is delivered to C52 right before the power interruption is kept nearly at a constant value during the power interruption. When the power supply is recovered and P2 is actuated, output analog signal e0 (arithmetic result right before power interruption) is read in via feedback means 6, multiplexer 4 and A/D converter 1 and arithmetic result right before the power interruption is utilized as the initial value of the operation. After this, P2 drives multiplexer 4 to select operated signal e1 and thus to secure the normal operation.

摘要： PURPOSE:To simplify the overall structure by applying the time duration signal instead of the operated signal and the operation signal to be supplied to the processor through comparison with the lamp. CONSTITUTION:Comparator 11 and 12 plus lamp signal generator circuit 4 are provided at the input side of processor 2 which features at least the time duration counting function and the operation function. Comparator 11 and 12 performs a comparison between analog signal Ex, operation constant signal Ef and lamp signal ER, and processor 2 supplies the time duration signal delivered from cimparator 11 and 12 as well as controls circuit 4. Furthermore, processor 2 obtains the digital signal corresponding to signal Ex and Ef by counting the time duration of the time duration signal applied through the counting function and then carries out the digital operation.
