Title: Automatic traveling vehicle
Inventor: TANAKA SHIGERU
IPC: G05D1/02
Filed: 1982-02-19
Abstract: PURPOSE:To prevent always surely the excessive operation of an actuator independently of the speed of a vehicle, by monitoring always it at intervals of a short time whether the steering angle reaches a target value or not. CONSTITUTION:In case of teaching, when the value of a counter 11 becomes a prescribed value, the output of an A/D converter 6 at this time is stored in a memory 12. Each time the vehicle travels for a cartain distance, the steering angle is sampled and stored in the memory in this manner. In case of playback, when the value of the counter 11 reaches the same prescribed value as the teaching case, the value of the memory 12 is read out and is loaded to a prescribed register of a CPU and is compared with the output of a steering angle detector 5 obtained through the converter 6. The solenoid of an electromagnetic valve 14 or 15 is operated on a basis of this comparison result. This comparison is performed in a time shorter than the time When the next target value is set. Thus, the excessive operation of the actuator is always prevented surely.

IPC: H03K3/037
Filed: 1986-02-10
Abstract: PURPOSE:To eliminate the need for a delay circuit with large scale even when a high speed logic element is employed by selecting the width of a clock signal larger than the sum between a clock signal skew DELTAt and a holding time th of the post-stage FF. CONSTITUTION:A delay circuit 31 is connected between the output of a FF 12 and an input of a FF 14. When a clock signal 18 descends, an input signal (data D1) 11 is inputted to the FF 12 at a point of time t1, an output signal 19 is obtained and a P-channel transistor (TR) 32 is turned off by the clock signal 18 inputted to the delay circuit 31 at the same time and an N-channel TR is turned off. Thus, the output signal 22 of the delay circuit 31 holds a level (data D0) just before the clock signal 18 descends. When a clock signal rises, a level (data D1) of the output signal 19 is outputted inversely at a point of time t2 as a delay output signal 22 and set to the FF 14 at the fall of the next clock signal 21. Thus, the output signal of the FF 12 is delayed by the clock pulse width, the holding time th is satisfied to guarantee the normal circuit operation. Thus, the delay of the clock signal width is obtained always and the circuit is constituted by the prescribed number of elements independently of the holding time th.
