Abstract: An ignition system includes an ignition coil which provides ignition voltage of one polarity, an igniter which supplies the primary current to the ignition coil at regular timings and a zener diode connected in series with the primary coil of the ignition coil. The zener diode shares a constant voltage drop of the opposite polarity at the secondary coil of the ignition coil, thereby reducing troublesome voltage induced in the secondary coil other than at regular ignition timings. On the other hand, the zener diode does not share the voltage drop of the ignition voltage at the regular timings, and thus no energy loss is incurred.

Abstract: An air/fuel ratio control system controls the supply of fuel to an internal combustion engine to achieve a target air/fuel ratio, based on the output of an air/fuel ratio sensor. The system may determine whether there is an abnormality in the air/fuel ratio sensor based on a comparison between a change of an air/fuel ratio correction coefficient, used to drive the air/fuel ratio to the target value, and a change of the target air/fuel ratio if the target air/fuel ratio has sharply changed.

Abstract: A bow with modified braking uses flexible bow limbs attached above and below a bow handle. The bow limbs have wheels that guide a bow string and form pulleys. The pulleys mechanically assist in holding the bow limbs when the bow string is drawn. A remotely controlled brake operated by a brake lever near the bow handle is used to limit bow wheel motion to reduce the difficulty of holding a drawn bow string. The remotely controlled brake has spring held brake contactors capable of elastic extension and retraction in the directions of bow wheel rotation that engage with a braking surface located on the bow wheel. The modified brake requires an archer to hold some of the pressure of a drawn bow string to prevent the bow wheel from extending the brake contactors which would release the bow string.
