Filed: 1979-02-05
Abstract: PURPOSE: To control an engine with accuracy by a method wherein the amount of flowing air is detected by a detector as a periodic signal, and a period computed by a clock pulse is provided in response to the signal.  
     CONSTITUTION: A periodic signal P is input to the first counter 204 via an AND circuit 202, and a clock pulse is inputted to the counter 204 from a clock pulse generator 206. In addition, the output of the counter 204 is inputted to a latch circuit 206A, and the output accompanying bits 8, 9, 10 with specified bit numbers is input to an OR circuit 208, then the output of the OR circuit 208 is input to the AND circuit 202, thus constituting an AND condition with the periodic signal P. As the first counter 204 makes 8 or 9 bit calculation, while the second counter 210 calculates the periodicity of the signal P, and as each of the counters processes the calculated value, it becomes possible to measure the amount of flowing air with extreme accuracy.

Title: Position controller
Inventor: SHIMOMURA TORU
IPC: G05B19/18
Filed: 1986-01-23
Abstract: PURPOSE:To facilitate sensor attachment and to control a position at high accuracy for a long period by permitting a noncontact type sensor and a rotary encoder to output the displacement position of a movable member and correcting and measuring the moving amount of the member. CONSTITUTION:The rotary encoder 32 interlockingly connected to an injection screw 6 so as to output a Z-phase output becoming a zero point position in the detection area of an approximity switch 30, outputs a position signal in accordance with the displacement of the screw 6. If the both outputs of the sensor 6 and the encoder 32 coexist, an original correction signal is outputted from an AND gate. A CPU stores the moving amount of the screw 6 from a mechanical original P to the time when the original correction signal is outputted as an original correction value DX. With a position at the time of outputting the original correction signal as zero, the moving amount from the original P is taken for a reference position, and the moving amount of the screw 6 from the position is added to the correction value DX so as to measure. Thus the switch 30 is of noncontact type to facilitate attachment. Besides, the detection of the moving amount can be attained with high accuracy for a long period.
