    摘要: An intrusion detecting apparatus for a vehicle comprising an ultrasonic transmitting/receiving sensor, an intrusion detecting unit for detecting whether or not a person intrudes into a passenger compartment, based on the received signal, a stopping unit for intermittently stopping the transmission from the transmitter, and a cover detecting unit for detecting whether or not the sensor is covered, based on the signal received after stopping the transmission of the signal and, in response to a predetermined condition representing that the sensor is covered, whereby it can correctly determine whether or not the sensor is covered, improving the accuracy of the detection of an illegal intrusion of a person. At least one of a transmitter and a receiver in the sensor and the intrusion detecting unit is also intermittently operated to reduce the power consumption.

    摘要: An acceleration sensor for detecting an acceleration in a plane, and having a housing, and a disk magnet arranged in a magnetic fludi stored in the housing. The movement of disk magnet is limited, i.e., a translational movement or rotational movement thereof can occur only in the plane, by projections formed in the housing, between which projections portions of the magnetic fluid having an increased density are formed adjacent to the poles of the disk magnet so that only a translational movement is allowed, or by small circumferential walls between the housing and the disk magnet and radial projections formed between end walls of the housing and disk magnet so that only a rotational movement is allowed. A Hall element issues a signal corresponding to a position of the disk magnet, to thereby determine the acceleration rate.

    摘要: A rotary drive apparatus includes: a bar yoke, a coil mounted on the bar yoke, and a cylindrical case, having a magnetic property for receiving the coil and the bar yoke therein. The cylindrical case has at least one salient-pole portion formed on the inside thereof in the vicinity of a portion where the coil is received. The rotary drive apparatus also includes a rotary member facing the salient-pole portion and spaced from the bar yoke and the salient-pole portion by a predetermined gap, so that the rotary member rotates between the bar yoke and the salient-pole portion, and is provided with at least one magnet having opposite magnetic polarities and arranged along the circumference of the rotary member and facing the salient-pole portion. The salient-pole portion, the magnet, and an end-of-the-yoke member form a magnetic circuit. The rotary member is rotated in response to magnetic flux generated at the end of the bar yoke by applying an electric current to the coil.
