摘要： A knocking suppression apparatus for an internal combustion engine has a noise removal circuit which is disposed between an acceleration sensor, which senses engine knocking, and a phase shifter, which controls the ignition timing of the engine. The noise removal circuit includes a switch which can be opened and closed to prevent signals from being input to the phase shifter, and a window comparator. When the window comparator determines that the output of the acceleration sensor contains high-level noise signals, the noise removal circuit opens the switch for a prescribed period to prevent the high-level noise signals from being input to the phase shifter and influencing the ignition timing.

摘要： In an electronic ignition apparatus, there are provided an ignition signal generator, an ignition circuit, an ignition-noise masking signal generator, a switching transistor and an ignition coil. The ignition signal of the ignition signal generator is supplied to the ignition circuit to produce a first ignition pulse and a second ignition pulse which is electrically isolated from the first ignition pulse. The first ignition pulse is applied to the switching transistor so as to switch the collector voltage thereof, whereby high voltage ignition pulse is produced in the ignition coil. The second ignition pulse is applied to the ignition-noise masking signal generator to produce an ignition-noise masking signal. The ignition-noise masking signal is superimposed on the ignition signal so as to mask the ignition noise at least when the high voltage ignition pulse is produced in the ignition coil.

摘要： An ignition timing correcting system for generating a reference signal at a reference angular position of a rotating internal combustion engine, and having an ignition signal leading it by a constant phase. In response to a control signal from a movable tap on a potentiometer, the ignition signal is retarded in phase to form a retarded ignition signal. The phase comparison of the two signals produces an advance or a retardation signal formed of a pulse train having a pulse width corresponding to the phase difference there-between. During the idling of the engine, the correcting signal drives an electric reversible motor in either a forward or reverse direction so as to move the tap on the potentiometer to adjust the control signal after the correcting signal has been converted to a driving pulse having a longer pulse width when correcting in a direction to correct an advance of said signal than the pulse width when correcting in a direction to correct a retardation of said signal with respect to the phase difference.

A first reproducing optical system forms a reproducing spot fixed with respect to the recording spot on the record surface for monitoring purposes, and a second reproducing optical system with the greater part of the optical components thereof common to the first reproducing optical system and also including a rotatable reflecting mirror for forming a tracking spot on the record surface. The tracking spot is movable on the recorded signal by the rotation of the mirror in response to the light reflected from the record surface for causing the tracking spot to accurately track the pitted signal on the record surface.

摘要： A vibration sensor is provided in which the depth of a caulked portion of the sensor's case is increased so as to increase the capacity of a recess defined between this caulked portion and the cover. The volume of a potting agent filling the recess can thereby be increased to improve the airtightness of the caulked portion and the reliability of the vibration detector. A vibration plate having cutouts circumferentially spaced along an outer, peripheral portion may be used in the vibration detector if the volume of the space formed on a lower side of the vibration plate is limited to about a few to ten percent of that of the space formed on the opposite, terminal side. The expansion of air in the spaces caused by a thermal shock is therefore substantially equal to the expansion of air contained in the space on the terminal side alone, so that vibration sensor can maintain sufficient airtightness and can be improved in reliability.

摘要： A knock control apparatus of ignition timing control type according to the present invention comprises, as one aspect thereof, a knock control level increasing means for augmenting a knock phenomenon suppressing function, so that, when the knock interval is short, the output characteristic of the integrating means is increased to raise the control level for suppressing the knock generating element in each cylinder of the engine, and that the integrating means output characteristic is invalidated when the condition of the internal combustion engine reaches the normal operating state. The knock control apparatus comprises, as another aspect thereof, a reset pulse generation circuit for resetting the voltage from the above integrator to zero at the interval of more than a predetermined number of times the ignition cycle and in synchronism with the ignition signal.
