Abstract: A housing structure for rotary connectors that have a flexible cable 4 spirally received within a space formed by a stator housing 1 and a rotor housing 2. Terminals 51 connected to electric conductors 42 of the flexible cable 4 are supported by a supporter 11 mounted in the stator housing 1. The supporter 11 has a barrier 13 having a path 12 through which the flexible cable 4 can be passed. An angle .theta. of an opening 12a positioned at an end position of the path 12 is larger than 180.degree.. A gap width t1 of the path 12 is approximately equal to a thickness t2 of the flexible cable 4.

Abstract: A rotary connector device having a stator housing 1 and a rotor housing 2 connected by an attachment 3. The attachment 3 fits to the rotor housing 2 and rotatably supports the stator housing 1. The attachment 3 includes a grease reservoir 33 disposed in sliding contact with the stator housing 1. An opening 25, through which a cord 61 connected to a flexible cable 4 is pulled outside, is disposed in the upper part of a rotor housing 2. The opening has a plurality of bumps 251 to 254 to clamp the cord 61. The stator housing 1 is constructed by assembling a side housing 11 and a bottom housing 12 together. A first gap 13 is formed in the area where the side housing 11 is connected to the bottom housing 12. A first side edge 71 of a slide sheet 7 is inserted into the first gap 13. A guide 15 of the bottom housing 12 for guiding the flexible cable 4 is formed with a second gap 14 into which the second side edge 72 of the slide sheet 7 is inserted.

Abstract: A basic fuel injection time is obtained based on engine speed and intake-air pressure in an intake passage of an engine downstream of a throttle valve of the engine. The basic fuel injection time is corrected by a correcting value based on a constant for a fuel injector and capacity of a chamber formed in an intake passage and on variation in intake-air pressure at every one rotation of a crankshaft of the engine when the idling state of the engine or throttle rapid closing are detected.

Abstract: A first lookup table is provided for storing a plurality of basic fuel injection pulse widths from which one of pulse widths is derived in accordance with engine speed and intake-air pressure. A second lookup table is provided for storing a plurality of maximum correcting quantities for correcting a derived basic fuel injection pulse width in order to correct deviation of air-fuel ratio due to change of valve clearance of the engine. A necessary correcting quantity is obtained by multiplying a learning coefficient and a derived maximum correcting quantity. A desired fuel injection pulse width is obtained by adding the necessary correcting quantity to the derived basic fuel injection pulse width. The learning coefficient is updated by 1/2 at every updating.
