Abstract: A highly stable engine failure diagnosing system free from influence of purging is presented. A monitoring apparatus for monitoring a fuel feed system of an internal combustion engine is provided with an A/F ratio detector and an A/F ratio controller for performing feedback control of the A/F ratio.

Abstract: In a conventional signal transmission device that transmits signals fed thereto to another device through a transformer, when the direction of the current flowing through the primary coil of the transformer is switched by switching devices connected in series between two different potentials, the timing with which the switching device that has been receiving current up to the moment is turned off is delayed from the timing with which the other switching devices are turned on or off to reduce overshoots and undershoots. This, however, may distort the square wave appearing across the secondary coil and make correct signal transmission impossible. To prevent this, a signal transmission device of the invention additionally has a waveform adjustment circuit that controls the delay time produced by a timing adjustment circuit according to changes in the states of control signals.

Axially slidable clutch elements are supported on a clutch cover, wherein centrifugal weights held by spring members are disposed at predetermined positions on the clutch cover. First retaining means on the clutch cover press the friction members and clutch members against each other so that power can be transmitted when the centrifugal weights are displaced. A first spring bearing member contacting one end of each of the spring members urges the centrifugal weights toward their initial positions while a second spring bearing member contacting the other end of each of the spring members is held in place on the clutch cover by second retaining means engaging the clutch cover. The first and second bearing members are axially movable relative to the input member.
