Title: Control device for air-fuel ratio of engine
Inventor: KANAMARU YOSHIKAZU
IPC: F02D45/00
Filed: 1990-03-23
Abstract: PURPOSE:To properly identify inactivity of an air-fuel ratio sensor without being affected by tansient lean fluctuation of air-fuel ratio by inhibiting identifying operation for inactivity of the air-fuel ratio sensor for a predetermined period of time from the initial period of the start of actuation of engine external loads. CONSTITUTION:The activity and inactivity of an O2 sensor 16 are identified according to the deviation between the maximum value Vamax and the minimum value Vamin of the output value Va of the O2 sensor 16 and also this identifying operation is inhibited for a predetermined time after external loads are exerted on an engine; even with noise of relatively small output level generated when the air-fuel ratio sensor is in its inactive state, mistakes in identifying operation can be prevented by eliminating the noise, thereby stopping actuation of feedback correction as accurately and promptly as possible.

Title: Driving cear of pulse motor
Inventor: ISOKAWA NOBUHIRO
IPC: H02P8/00
Filed: 1978-06-22
Abstract: PURPOSE:To maximally extract the output of a pulse motor, by detecting and adjusting the functioning conditions of the movement of a step of the pulse motor, and by generating command pulses at the optimum timing. CONSTITUTION:Since mean driving torque greatly changes by the locations of the angles of revolution of a rotor in the case when changing over excitation, a point that must extract the maximum driving torque is detected by adjusting these  change-over points. The relative angles of an output shaft of a pulse motor 1 and an input shaft of a pulse generator 4 are beforehand regulated so that detecting pulses be generated slightly before the maximum driving torque excitation change-over point by means of a coupling 3, and turned. Pulses generated at the pulse generator 4 are input to a trinary ring counter 9 through a shaping circuit 5, a pulse delay circuit 6, an and gate 7 and an or gate 8, and command pulses that can change over the optimum excitation phase are applied through a power switch 10.
