IPC: F02P5/15
Filed: 1987-08-28
Abstract: PURPOSE:To hold engine characteristics in an excellent state, by a method wherein an air-fuel ratio and an ignition timing are controlled so that a ratio between a pressure average effective pressure in a cylinder and a fuel weight per 4 cycles, detected from a rotation speed and an injection period, is held at a given value. CONSTITUTION:During running of an engine, an incylinder pressure signal, detected by a pressure pickup 11 mounted in a state to be attached to an ignition plug, is inputted to a pressure signal processing circuit 12. An average effective pressure is calculated therein to generate an electric signal responding to an average effective pressure, and the signal is inputted to a microcomputer 8 for controlling an engine and an ignition control circuit 10. A ratio between the average effective pressure and a fuel weight per 4 cycles (suction, compression, explosion, and exhaust), detected from an engine rotation speed obtained from an output from a crank angle sensor 17 and a separately computed injection period, produces one variable, and a fuel injection amount from an injection valve 4, i.e. an air-fuel ratio, is controlled and the ignition timing of the ignition plug is controlled so that the ratio is held at a given value.

Title: Ink jet recording apparatus
Inventor: NAGOSHI SHIGEYASU
IPC: B41J2/07
Filed: 1993-08-31
Abstract: PURPOSE:To avoid lowering the recording density even in the same quantity of ink discharge as in a conventional manner by forming an ink jet recording apparatus capable of multipath recording to have a driving order of discharge elements being variable every recording path. CONSTITUTION:A nozzle driving order is such that Nos. 1, 2 nozzles are driven at first in the first path, and the reminder nozzles Nos.3, 4 are not driven and the order is moved to an adjacent line of dots. Since the driving interval between No.1 nozzle and No.2 nozzle is made twice as long as (t) 1 in a conventional manner, the interval between No.1 nozzle and No.2 nozzle in the X direction becomes twice relative to a conventional manner. Similarly, in the second path, No.3 nozzle and No.4 nozzle are driven at a time interval being twice as long as (t) 1. In this instance, the maximum time interval can be controlled to (t) 1X3 times because it is two path printing. Herein, adjacent upper and lower dots are disposed so that each dot is allowed not to overlap with each other ununiformly in consequence of its relation among the recording density P, dot diameter (d) and driving differential L, thereby ensuring printing density having no recording medium viewed therein.
