摘要:
An access control system for controlling the access to a storage which is divided into a hardware area inaccessible to ordinary programs and a software area for storing the ordinary programs, includes an address registration device and access controller. The address registration device has a plurality of entries, each of which holds a previously-used address of the storage and a flag for indicating whether the previously-used address is included in the hardware area or not. Further, the address registration device indicates whether an address at which the storage is to be accessed, is present in the address registration device or not. The access controller controls the access to the storage in accordance with the flag from the address registration device, a signal indicative of whether the to-be-accessed address of the storage is present in the address registration device or not, and the access mode which is now used.

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.

A suspension arm supporting structure for overhead attachment of an upper suspension control arm to the vehicle body using a pair of bolts, each with a large head protruding downwardly towards the wheel, a hole in each head aligned along the same horizontal axis, and a horizontal bolt extending between the two holes in the heads of the vertical bolts to pivotally connect an upper suspension control arm to the vehicle body.

A seal member and tolerance compensator which includes a body portion, an integral leg portion, and several deformable locator and sealing extensions. The leg portion is received in a compressed manner between two adjacent components of a pivotally connected assembly which have axial tolerances. At least one of the surfaces of the leg portion is provided with grooves and projections such that when the projections are compressed between adjacent components by relative motion within the assembly or tolerances within the assembly, the elastic material of the protrusions will flex into the surrounding grooves.
摘要:
A data processing system is disclosed in which it is detected whether or not data to be read out from a buffer memory with a single access are spread over a plurality of blocks, which are used as the unit for storing data in the buffer memory, and, when the presence of block cross is detected, addresses of blocks including a desired operand are generated as addresses in banks making up the buffer memory, whereby the operand is read out from adjacent blocks by a single read-out operation.
摘要:
A circuit outputs different subsidiary address data depending on operand address data contained within operand designation fields and operation codes of system instructions. A control storage, which stores microinstructions, is accessed for the initial microinstructions, contained within microinstruction sequences for system instructions, at storage locations specified by the operation codes and the subsidiary address data. As a result, different microinstruction sequences for system instructions with the same operation code can be initiated depending on the operand address data, without using any microinstructions for testing the operand address data.

A suspension for use in a motor vehicle such as an automobile includes a knuckle arm for supporting a wheel, the knuckle arm having upper and lower ends, an upper arm having an end pivotally coupled to the upper end of the knuckle arm and adpated to extend substantially transversely of the vehicle frame, at least one lower arm having an end pivotally coupled to the lower end of the knuckle arm and adapted to extend substantially transversely of the vehicle frame, a trailing arm having an end pivotally coupled to the knuckle arm and adapted to extend substantially longitudinally of the vehicle frame, and a joint structure pivotally coupling the trailing arm to the knuckle arm for angular movement of the trailing arm about an axis of the vehicle frame.

An independent wheel suspension system includes a pair of upper lateral link members and a pair of lateral link members for supporting a wheel carrier to the vehicle body. By providing a difference in elevation between the outer ends of the link members for the upper and/or the lower pair of lateral link members, an anti-dive property can be obtained. Further, by providing an appropriate inclination to the rear lower lateral link member, the tendency to form a toggle between the knuckle arm of the wheel carrier and the tie rod is reduced. Also, by making the front lateral link member more upwardly inclined than the rear lateral link member for each of the pairs, an anti-dive effect can be produced without changing the caster angle and other property of the suspension system during cornering maneuvers.
摘要:
In a four-link parallel link vehicle suspension system, a generatrix or an imaginary king pin is defined as a line connecting an instantaneous center of rotation of the knuckle as defined by an upper pair of lateral links with another instantaneous center of the rotation as define by a lower pair of lateral links and the range of the intersection of the imaginary king pin with the tread contact surface is minimized for the purpose of reducing the change in the force required to maintain a certain steering angle of the wheel. Thereby, the handling of the vehicle is improved through the reduction in change in the force required to maintain a steering angle of the wheel while maintaining the freedom of parameter setting which is intrinsic to the four-link parallel link vehicle suspension system.
