To provide a torque detecting device having a sufficient mechanical strength, capable of accomplishing an accurate torque measurement, having a processability excellent for mass-production, and effective to eliminate problems associated with damages which would be brought about during a heat treatment. This torque detecting device includes a target area subject to torque detection (3) provided in a surface region of a torque transmitting shaft (2) made of a steel material; a detecting coil (4) provided in a non-contact fashion in face-to-face relation to an outer periphery of the target area subject to torque detection (3); and a detection signal processing circuit (5). The target area subject to torque detection (3) is a layer of magnetostrictive material comprised of an Al diffusion layer. This diffusion layer contains Al diffused in a steel material in a concentration which gradually decreases from the surface in a direction radially inwardly of the torque transmitting shaft (2).

A digital data storing method is provided in which digital data whose content varies as the time elapses is partially encrypted for each predetermined period τ at a predetermined time interval T. The encryption is done for the ratio of the period τ of the encrypted part to the predetermined time interval T and period τ of the encrypted part to be sufficiently small. The digital data thus encrypted is stored.

To provide a bearing device for a wheel, in which a preload control is easy and a uniform amount of preload can be applied with a bearing seal being mounted, the bearing device for the wheel includes an outer member, an inner member and double rows of rolling elements interposed between the outer member and the inner member. The outer member has a flange on an outer periphery thereof and also has an inner periphery formed with two rolling surfaces. The inner member is formed with rolling surfaces opposed to the rolling surfaces of the outer member. The double rows of the rolling elements are interposed between the rolling surfaces of the outer member and the inner member. A sensor for detecting the amount of preload of the bearing is provided in one of the outer and inner members.

A sensor-incorporated wheel support bearing assembly includes a stationary outer member having a plurality of raceway grooves defined in an inner peripheral surface thereof, an inner member made up of a rotatable hub axle and an inner race segment mounted on an inboard end portion of the hub axle with a vehicle wheel being supported by the hub axle. The inner member has a corresponding number of raceway grooves defined in the hub axle and the inner race segment, respectively. Rows of rolling elements are interposed between the outer member 1 and the inner member. A to-be-detected member in the form of a magnetostrictive element is formed in a portion of the outer periphery of the hub axle adjacent an inboard side and remote from the raceway groove. At least one force detecting unit for detecting a change in magnetic strain induced in the to-be-detected member is provided in an outer race, which is a non-rotatable member, for detecting a force acting on a shaft coupled with the inner member.

A clip includes: a pin having a head and a shank; and a grommet having a collar and a leg. The leg of the grommet is divided into a plurality of expansion leg pieces by means of slits extending along an axial direction. The expansion leg pieces of the leg are expanded outwardly by the insertion of the pin into an inner side of the grommet, so as to clamp plate-like members by the collar and the expansion leg pieces. The leg of the grommet has resilient beams which project outwardly of the expansion leg pieces on a collar side when the pin is inserted into the inner side of the grommet.

A bearing assembly (1) of the present invention includes a rolling bearing (1) including a rotatable raceway member (2) and a stationary raceway member (3). This bearing assembly also includes a to-be-detected member (7) carried by the raceway member (2) and having a magnetic characteristic which cyclically varies in a direction circumferentially of the to-be-detected element (7) and has a cycle matching with one complete rotation of the raceway member (2), a magnetic sensor unit (8) carried by the raceway member (3) in face-to-face relation with the to-be-detected member (7), and a magnetic detecting circuit (9) for supplying an electric power to the unit (8) and for processing an output signal from the unit (8) to provide an output to an external circuit. The magnetic characteristic of the to-be-detected member (7) represents a substantially sinusoidal waveform rising and falling more steeply than a sinusoidal waveform at a zero-crossing point.

In face-to-face relation with this to-be-detected portion 1, a magnetic detecting portion 2 is secured to a stationary race member 33. The magnetic detecting portion 2 is made up of magnetic sensors arranged in a direction circumferentially of the race members 32, 33 and each capable of providing an analog output. A differential output generating means 7 is provided for processing a differential output of the adjoining two magnetic sensors 2a and 2b as an encoder signal for one phase.
摘要:
The invention intends to transmit audio signals of multiple channels in such a manner as to be able to decode and reproduce them in real time on the receiving side. Digital signals of multiple channels are each divided into one or more fragments in an audio signal input circuit, and the fragments of multiple channels are each encoded into coded fragment data by an encoder of the corresponding channel. At the time when transmission of one of the coded fragment data is ended, a multiplexer selects another of the coded fragment data of multiple channels to be next transmitted, and supplies it to a transmitting circuit.
