A suspension for a motor vehicle has a link structure and a spring interposed between the link structure and a vehicle frame. The link structure comprises a trailing arm extending substantially longitudinally of the vehicle frame and having a front end pivotally coupled to the vehicle frame and a rear end supporting a wheel, upper and lower arms extending substantially transversely of the vehicle frame and each having one end pivotally coupled to the vehicle frame and an opposite end pivotally coupled to the trailing arm in the vicinity of a rear end thereof, and a compensation link having one end pivotally coupled to the vehicle frame and an opposite end pivotally coupled to the trailing arm. The suspension is relatively lightweight, inexpensive to construct, and has excellent performance.

A trailing arm joint structure includes a knuckle for supporting a wheel and a substantially plate-like trailing arm lying in a vertical plane and having a front end adapted to be pivotally coupled to a vehicle frame and a rear end pivotally coupled to the knuckle. The knuckle has a front bifurcated portion composed of first upper and lower joint fingers extending forwardly and spaced vertically from each other, the knuckle having a link joint positioned between the first upper and lower joint fingers. The rear end of the trailing arm has a rear bifurcated portion composed of second upper and lower joint fingers extending rearwardly and spaced vertically from each other, the front and rear bifurcated portions being held against each other with said first and second upper and lower joint fingers being fastened together.

A shock absorber/coil assembly in a motor vehicle suspension includes a fluid cylinder, a piston rod movable into and out of the cylinder, a vibration isolator mounted on an end of the piston rod, and a coil spring disposed around the fluid cylinder and the piston rod. A mount assembly for mounting the shock absorber/coil assembly includes a retainer adapted to be mounted on the vibration isolator and to be attached to a motor vehicle frame, a spring seat adapted to engage an end of the coil spring, and a thrust bearing interposed between the retainer and the spring seat and adapted to extend around the vibration isolator, the thrust bearing including a pair of first and second races and a plurality of balls rotatably disposed between the first and second races, the first race engaging the retainer and the second race engaging the spring seat.

A magnetic recording and reproduction system of the helical scan type is disclosed. During the recording process, pilot signals for reproduction tracking control are sequentially recorded by the rotary magnetic head in recording tracks in proximity to each other in superimposed relation with the television signal to be recorded. During the normal reproduction process, from the level difference between the crosstalk signals of the pilot signals reproduced from the recording tracks adjacent to the recording track to be reproduced, a tracking error is detected to control the relative positions of the recording track and the reproduction scanning traces of the reproduction magnetic head. During the reproduction process at a speed different from that for recording, on the other hand, a pulse signal is produced at a time point when the crosstalk levels of the pilot signals reproduced from the tracks adjacent to the recording track to be reproduced coincide with each other. This pulse signal is used to maintain a predetermined positional relation between the recording track and the reproduction scanning traces of the reproduction magnetic head thereby to produce a superior reproduced image.

A method for positioning a composite head comprising a control head and an audio head in a rotary head type magnetic video recording and reproducing apparatus at a precise spacing relative to a mounting position of the rotary head is disclosed. A video signal is recorded intermittently for each group of a predetermined number of video tracks on a reference tape and an audio signal is also recorded intermittently in association with the intermittently recorded video signal. The composite head is adjusted and positioned such that the intermittent relationship existing between a reproduced video signal and a reproduced audio signal is the same as the intermittent relationship existing between the video signal and audio signal during recording.

A four-wheel steerable motor vehicle has a mechanism for steering front wheels in response to turning motion of a steering wheel, and a mechanism for steering rear wheels in response to steering of the front wheels. The rear wheels have camber with respect to ground which is more negative than camber of the front wheels with respect to ground. The motor vehicle also has front wheel suspensions supporting said front wheels, respectively, and rear wheel suspensions supporting said rear wheels, respectively, the front and rear wheel suspensions being of the double-wishbone type.

A VTR of helical scan type includes a rotary magnetic head fixed on an electro-mechanical converter made of a piezoelectric element and adapted to be displaced along the width of a recording track. In this type of VTR, the rotary head can follow the curving of the recording track, and therefore a superior reproduction output is always produced. Also, a noiseless reproduction image is provided at the time of special reproduction with a tape feed rate different from the recording speed. When the electro-mechanical converter is driven, the average DC component of the drive voltage is desirably reduced to zero to secure a dynamic range effectively. Especially this consideration is necessary to maintain the service life of the piezoelectric element which may make up the electro-mechanical converter. The average DC component of the drive voltage of the electro-mechanical converter is reduced to zero, or specifically, a weighted average of the drive voltage for head scanning is produced, and the drive voltage is appropriately processed during the period when the head is not in contact with the tape.

A storage control system controls the update operations on two buffer address arrays in a data processing system in which a plurality of processors are connected to a shared storage, at least one of the processors having a buffer storage. The first buffer address array is the directory of buffer storage. The second buffer address array contains the same data as that of the first buffer address array. The storage control system updates first the content of the second buffer address array then that of the first buffer address array in response to a block transfer to the buffer storage of the own processor and a store operation conducted by other processor on the shared storage. The storage control system permits to accept a new access request occurred in the own processor on condition that a block transfer to the own processor is finished and that the first buffer address array is updated in association with the block transfer.

A storage system includes a storage for storing data, and a store buffer for temporarily buffering data before storing it into the storage. A store request is applied to the store buffer, and store data accompanied by the store request is applied to the store buffer. When a fetch request for the storage does not exist, the store data buffered in the store buffer is transferred from the store buffer to the storage and is stored therein.
