摘要： Disclosed is an acrylic sol for a sound insulating underbody coating. It includes acrylic polymer fine particles, a plasticizer, a filler, a plasticizer, a blocking type urethane resin, a curing agent and a foaming agent. Since it includes the acrylic polymer particles as a major constituent unit, it does not generate a hydrogen chloride gas and dioxins when it is burned. Moreover, since the paint film resulting from the acrylic sol has a net-shaped structure by the cross-linkage reactions of the urethane resin, and since the bulkiness of the paint film is increased by the foaming agent, it has a good cold resistance and adhesion property toward automotive steel plates, and effects a superb chipping resistance and sound insulating performance.

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： This invention relates to an ignition distributor for an internal combustion engine and more specifically relates to a novel reluctor included in an ignition distributor for discriminating between cylinders of an engine. The reluctor has an elongated shape and is arranged relative to the rotating shaft of an ignition distributor so that the gravity center of the reluctor is located exactly on the rotational axis of the shaft. This arrangement enables the rotational movement of the shaft to be concentrated, so that the wear to which the bearings supporting the shaft is subjected is significantly reduced. The reluctor is attached to the governor base of an ignition distributor without any rivets by virtue of the novel configuration thereof, so that a reduction in the number of parts can be achieved, together with reduction in the total production cost.
