Filed: 1986-03-26
Abstract: PURPOSE:To simplify the constitution of a trigger signal generating circuit by using a deciding means and a trigger control means in place of a switch. CONSTITUTION:A setting means 11 gives a function code to a deciding means 12 via a register 2 and also the trigger conditions to a trigger control means 13.

Title: Brake controlling method
Inventor: IIDA KENNOSUKE
IPC: B60T8/66
Filed: 1980-05-22
Abstract: PURPOSE: To prevent locking of a wheel of a car during braking of the car by comparing, after setting an operation initiating valve of hydraulic pressure control valve adapted to operate to lower the rate of rise of braking pressure, the operation initiating value with a car body deceleration to determine a point of time at which the hydraulic pressure control valve should initiate its operation.  
     CONSTITUTION: Output signals of a car body deceleration detector 1 and a brake hydraulic pressure detector 2 are applied to a load calculator 4 of a control circuit 3 which calculates the weight of the car. An operation initiating point setting circuit 5 determines a car body deceleration at which a hydraulic pressure control valve 7 should initiate its operation. A comparator 6 receives as one input thereto the set deceleration signal of the circuit 5. The comparator 6 compares an actual deceleration signal from the car body deceleration detector 1 with the set deceleration signal and provides an output signal when both signals coincide with each other in order to cause the hydraulic pressure control valve 7 to operate to lower the rate of rise of braking effort. Locking of a wheel during braking is thus prevented thereby.

Furthermore, there never develop stagnation of printing paste at the four corners. In addition, inasmuch as cleaning can be positively conducted from corner to corner because of ready cleaning, there is no solidification of paste due to cleaning failure, and therefore, the occurrence of printing failure can be prevented.

Title: Bite reducing method in tracer control device
Inventor: MATSUURA HITOSHI
IPC: B23Q35/12
Filed: 1984-04-06
Abstract: PURPOSE:To make a biting quantity in time of high speed operation reducible, by increasing a compensation value in an axial direction in proportion as an axial speed grows larger, while slowing down a coppying rate at a time when a time differentiation value of the compensation value goes beyond the specified slice level. CONSTITUTION:Compensation values epsilonXC and epsilonZC are outputted from multipliers MP2 and MP4 of a compensation circuit DCC1 and impressed on differentiation circuits DFX and DFZ if a bite detection circuit at a rear stage. And, a time differentiation value of these compensation values epsilonXC and epsilonZC is the larger the higher than another time differentiation value of a shaft displacement quantity epsilonX and epsilonZ, and thereby if these compensation value epsilonXC and epsilonZC are clamped to these shaft displacement quantity epsilonX and epsilonZ, a biting quantity in time of low speed operation can be made into sameness in the past. In consequence, when the biting gets generating, the time differentiation value of displacement values epsilonX and epsilonY is not more than the setting value S1, though, at least one side of time differentiation values epsilonXC' and epsilonZC' becomes more than the setting value S1 so that biting detecting time comes earlier than the conventional case and a biting quantity is reducible, thus the detecting time is earlier the speedier in the shaft speed.

Abstract: PURPOSE:To stably control a tensile force by providing means for the detection of a supply reel and a take-up reel, the computation of the inertia of each reel, that of the acceleration torque of the take-up reel, the discrimination of acceleration, the computation of the acceleration compensation torque of the take-up reel and that of back torque, and addition. CONSTITUTION:A detector 8 outputs S-reel radius information Rs, and a detector 12 outputs T-reel radius information RT. A computing element 13 computes the inertia Js of an S-reel based on the information, and a computing element 14 calculates the inertia JT of a T-reel. Also, a computing element 15 computes the acceleration torque of the T-reel from the T-reel torque information QT of a terminal 5 and the information RT. A discriminator 16 discriminates the acceleration/deceleration direction of the T-reel, and a computing element 17 performs the computation of compenstation torque in the fluctuation of the tensile force due to the acceleration/deceleration of the T-reel. The information QB of a back torque computing element 9 is added on the information CMPT of the computing element 17 at an adder 18, and tensile force control error information QS is outputted to an S-reel motor driving circuit 10. By employing such tensile force control system, it is possible to suppress the fluctuation of the tensile force by the difference of winding diameter or the acceleration/ deceleration without preparing a tensile force detection sensor.
