A method and apparatus for counting yarn splicing operations for each of the spindles in an automatic winding machine provided with a plurality of winding spindles and an automatic knotting machine and in which relative motion of said spindles and said knotting machine causes the knotting machine and successive spindles to be adjacent each other for carrying out a yarn splicing operation when necessary. A pulse signal is generated each time the knotting machine and a spindle are adjacent each other during the relative motion of the knotting machine and the spindles, the pulse being of relatively short duration when the knotting machine is adjacent a spindle for a time insufficient to carry out a splicing operation. The apparatus discriminates between the long and short duration pulses for each spindle, and the long duration pulses for each spindle are counted as an indication of the occurrances of a splicing operation for that spindle.

Even when an engine is started in various combustion states, an excessive increase in engine speed at the start of the engine is suppressed without an influence of the combustion states and with an excellent responsiveness. Ignition timing (or a combustion injection amount) at the start of an internal combustion engine is corrected in accordance with a crank angle cycle ratio which is a ratio of a combustion period crank angle cycle and a reference crank angle cycle.

In a fuel injection device, a driving unit structure has a magnetic aperture, in which an inner diameter is gradually enlarged toward the mover side, provided in an inner peripheral surface of the magnetic core. It is possible to reduce magnetic delay time upon valve opening from the supply of the electric current to the coil to the rise of magnetic flux and magnetic delay time upon valve closing from the stoppage of the electric current to the coil to reduction of magnetic flux, by providing a magnetic aperture in the inner peripheral surface of the magnetic core. Thus it is possible to improve the dynamic responsiveness upon valve opening and valve closing.

Provided is a control device of a direct injection engine, the control device that can prevent the amount of emission of soot from increasing and the exhaust performance from worsening when a restart request is made before an engine is stopped after an idle stop condition is satisfied. When a restart request is made before an engine is stopped after an idle stop condition is satisfied, at least one of the number of fuel injections in one combustion cycle and the air/fuel ratio of an air fuel mixture used for combustion is changed for each cylinder according to a piston position at that time.

A fuel injection control apparatus includes a computing unit that calculates a pulse width for a pulse signal which drives the valve of a fuel injector, based on the operational state of the internal combustion engine and fuel pressure detected by a fuel pressure sensor. After a valve-opening command has turned on and a high valve-opening current has been supplied to open the fuel injector valve, a fuel injector driving signal waveform command unit discharges the current and supplies a small hold current Ih2 to maintain the injector's valve-open state. After the elapse of a predetermined rapid-discharge starting time from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit rapidly discharges the current until the hold current Ih2 has been reached.
