摘要： PURPOSE:To improve accuracy in cutting and solve problems such as noise, wear, breakage, etc. of mechanism portions of a cutting apparatus by making the speed commanding property of a control unit the fourth degree curve property. CONSTITUTION:High accuracy in cutting by a set length requires that the integration value of speed commanding Vs curve with respect to time t=0-t3 is equal to the circumferential length of shear edge and speed Vs is equal to speed Vl in time t=t2-t3. Thus, the Vs curve will do if it satisfies said two requirements, and here it is given as the composition of fourth degree curve a'-b'-c' and straight line c'-d'. The fourth degree curve is provided since it is simple to calculate and thus the accuracy in cutting is improved.

摘要： PURPOSE:To provide a proper cut-off length and improve the accuracy of cut-off in a cut-off controller for a corrugated fiberboard cutting apparatus or the like by detecting a position of a cutter engaging a material with a cut completion detector. CONSTITUTION:A material 1 like corrugated fiberboard is cut off into a predetermined length by a rotating cylinder 2 with a shear edge 3. A material moving line is provided with a material position measuring wheel 4 to which is connected a pulse oscillator 5 so that pulses are generated to a material position counter 11 and a controller 8 detects the material position from this counter 11. The position of the shear edge 3 is determined by pulses generated from the pulse oscillator 5 connected to a motor 6 according to the rotational frequency of the cylinder 2 and counted by a shear edge position counter 12. The completion point of cut-off is detected by a cut-off completion detector 9 and then the material position counter 11 and shear edge position counter 12 are reset to zero by reset pulses generated from the cut-off completion detector 9.

摘要： PURPOSE:To save power consumption and reduce noise production by making the speed change of triangular pattern that of trapezoidal one. CONSTITUTION:The factor is reduced from 16 to 27/2=13.5 to save about 15.6% of power consumption compared with the case of triangular pattern by providing P(trapezoidal pattern)=27/2.(LO-LR) /(LO-LSYN) .Vl . Further, the life and noise of mechanism section such as shear drive section are improved. That is, in the case of trapezoidal pattern, since the acceleration change is reduced, the mechanical shock is reduced so that the life and noise of the mechanism section is respectively elongated and reduced.

摘要： PURPOSE:To improve the efficiency of transmission, by discriminating a device for receiving unit from a parity pattern. CONSTITUTION:The transmission information is latched by a latching circuit 1, and a data of a prescribed bit is obtained. A parity generator 2 performs a parity calculation from the data of a prescribed bit and a parity pattern showing the receiving unit number in order to produce a hamming code of a prescribed bit. A parallel-serial converter 3 converts a parallel data into a serial data and transmits it. This serial data is received by a receiver 11 and then converted into a parallel data through a serial-parallel converter 12. Then a parity generator 13 produces a parity pattern from the hamming code of a prescribed bit. A parity pattern comparator 16 compares a parity pattern showing a device number with a parity pattern of reception data. It is known that the parity pattern is 001 if no error is detected. However, the pattern varies if an error arises.

摘要： PURPOSE:To provide high cutting accuracy and to enable high-speed cutting by providing a laser scanning carriage which irradiates laser light on a material to be cut and cuts said material and a moving mechanism which moves said carriage. CONSTITUTION:The laser light 24 emitted from a laser generator 21 is conducted through a waveguide 23 to the reflection mirror 25 of a laser scanning carriage 22 and is irradiated by the mirror 25 onto corrugated fiberboard 1 moving at a specified speed. The carriage 22 is moved on rails 27 at a specified speed by means of a chain 30 in this stage. The corrugated fiberboard 1 is therefore cut by the laser light 24 from the mirror 25 according to the movement of the carriage 22.

摘要： PURPOSE:To use a frequency channel effectively and to eliminate a failure at radio interference, by informing a vacant channel detected at a reception unit of a command receiver of a command transmitter to a remote station and transferring a channel at radio interference automatically. CONSTITUTION:For example, electromagnetic waves fg from the command transmitter are normal and electromagnetic waves fc from the command receiver are interferred, the transmitter changes over channels of the reception unit 10 and a vacant channel is detected. The detection of the vacant channel is done with a squelch output from the unit 10. The squelch is set on when the strength of a reception electric field is on or below a level (no electromagnetic wave interferring with the reception frequency exists). The channel selection is stopped when the squelch output is set on and the channel information of the fc and the switching command are irradiated on the waves fg. The receiver changes over the channel of the fc based on the command from the transmitter.

摘要： PURPOSE:To drive a controller while improving hysteresis characteristics without adding a position sensor by sending a correction signal, generated by adding a command signal to a signal from a function generator, to the controller. CONSTITUTION:When a command signal X1 is inputted from a command device 1 to the 1st register 2, the register 2 stores the X1 and outputs a signal R1=X1. In this case, the value R2 of the 2nd register 3 is 0, so the output C of a subtracter 4 is equal to the X1 and inputted to a function generator 5. Since C=X1, namely, C>0, the generator 5 sends a signal (a) as its output (d) to an adder 6, which adds the (a) to the command signal X1 by e=R1+d to output a correction signal (e). It is amplified by a factor K at an amplifier 7 to input a signal I=K(X1+a) to a stroke valve, thus obtaining a storke signal y=Y1. Consequently, the relation between the command signal (x) and the amount of a stroke is varied according to ideal characteristics to remove the influence of hysteresis.
