Title: Control device for engine
Inventor: NISHIMURA HIROBUMI
IPC: F02D41/10
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent the sudden increase of NOX exhaust quantity just after transfer by controlling the air-fuel ratio to a specified value or less until a prescribed holding time is passed after the transfer from the accelerating state of an engine to the steady operating state. SOLUTION: When the transfer from accelerating state to steady operating state of an engine 1 is judged on the basis of the change of engine rotating speed or accelerator opening by an ECU 30, the air-fuel ratio is controlled to rich as in the accelerating state (the air-fuel ratio is 15 or less) until a prescribed delay time is passed after the judgment of the transfer. Therefore, since NOX purifying ratio is never reduced even if the catalyst temperature of a catalytic converter 23 is increased because of the high temperature of exhaust gas until the delay time is passed, a sudden increase in NOX exhaust quantity of the engine 1 just after the transfer to steady operating state can be prevented.  Since the catalyst temperature is reduced to a prescribed temperature having a high NOX purifying ratio after the lapse of the prescribed delay time, NOX in exhaust gas can be sufficiently purified while controlling the air-fuel ratio to lean.

Title: Method of controlling line feed motor for printer
Inventor: KIKUCHI KO
IPC: B41J19/76
Filed: 1986-10-09
Abstract: PURPOSE:To prevent step-out of a pulse motor due to mechanical loosening of components during line feed of a medium, by rotating a motor forward with a larger rotary angle theta2 than a rotary angle theta1 corresponding to the feeding amount of the medium then rotating the motor rearward by a differential rotary angle such that the rotary angle of the motor will be Q1. CONSTITUTION:At fist, a pulse motor is rotated by an angle theta2. During rotation, a load torque T1 is produced through friction during traveling of a medium irrespective of the rotary angle of the pulse motor. Consequently, when the pulse motor is stopped, a torque tm1 caused by the recovery force is applied in the opposite direction from the rotary direction of the pulse motor. Since the pulse motor is rotating excessively by the amount of (theta2-theta1), if the pulse motor is rotated reversely by an angle (theta2-theta1) its rotation is promoted by the recovery force so as to stop the pulse motor with the rotary angle of exactly theta1. Consequently, the rotary angle is changed from thetam1 to (thetam1-theta2) by the recovery force so as to reduce the torque caused by the recovery force from Tm1 to Tm2. Consequently, step-out of motor can be prevented.
