摘要： The invention provides a magnetic object motion sensor which can operate with high accuracy not only when a magnetic object moves at high speeds but also even when it moves at low speeds, which can be produced with a greater production tolerance and a greater dimensional tolerance. The magnetic object motion sensor includes: magnetoelectric transducer elements disposed opposite protrusions of a moving magnetic object; a magnet for generating bias magnetic flux toward the magnetoelectric transducer elements; unbalanced bias producing means for producing imbalance in the magnetic field sensitivity between the magnetoelectric transducer elements; a differential amplifier for amplifying in a differential fashion the electric signals output by the magnetoelectric transducer elements; a waveform shaping circuit for converting the differential signal output by the differential amplifier to a pulse signal corresponding to the edges of the magnetic material protrusion; the unbalanced bias producing means producing a difference in the amplitude of the magnetic flux density between that applied to one element of the pair of magnetoelectric transducer elements and that applied to the other element so that the difference in the electric signal level corresponding to the difference in the amplitude of the magnetic flux density becomes greater than the hysteresis of the waveform shaping circuit, thereby, in effect, introducing imbalance in the sensitivity between the magnetoelectric transducer elements.

摘要： A nailing machine includes a body, a driver extending downwardly from the body and vertically reciprocally movable for driving nails, and a driver guide for guiding the driver. A contact arm is movable between a lower first position and an upper second position and has a lower end for abutment on a work. A magazine is mounted on the body for feeding the nails into the driver guide. A trigger is operable by an operator for driving the driver. A trigger control device is interlocked between the trigger and the contact arm for permitting the driver to be driven by the operation of the trigger only when the contact arm is positioned in the upper second position. An idle driving prevention device is operable independently of the trigger control device for preventing the driver from being driven through operation of the trigger when the amount of the nails has been reduced to a predetermined amount.

In this magnetic sensor, electronic components located near a connector are connected to a base and disposed in such a manner that the longitudinal axis of those electronic components are substantially perpendicular to the longitudinal axis of the base.

摘要： An internal combustion engine control apparatus for performing the timing control such as ignition and fuel injection timing control with high accuracy even in a transient operation state such as acceleration or deceleration. A ratio between a first interval period extending from a first reference position to a second reference position and a second interval period extending from a second reference position to the first reference position is determined. A correcting coefficient is calculated on the basis of the ratio. By using this correcting coefficient, the predicted reference position period is calculated, on the basis of which the timing control is performed.
