摘要:
A system and method for preserving the order of data items through a divergence-and-reconvergence of two or more paths in a hardware device. A host processor may write a first token to a first path in the hardware device. A convergence unit in the hardware device may receive and store the first token in a synchronization register. The host processor may poll the synchronization register to determine when the first token arrives in the synchronization register. In response to determining that the first token has arrived in the synchronization register, the host processor may safely write a sequence of one or more data items to a second path in the hardware device.
摘要:
A small size epicyclic gear system in which the mating between gear housings is purposefully made with some play to allow a certain degree of relative movement to accommodate machining runout errors in the manufacture of the gears. A castellated cap fastened to the motor engages with a castellated gear reduction body. The tolerances built into the cap and gear reduction body allow relative radial movement therebetween to reduce binding of the gears during rotational positions in which the gear component runout tolerances are additive.

A motor module (51) holding a plurality of motors as a unit. The motor module (51) is adapted for mounting to the main body (49) of a reinstatement cutting machine (20). The motor module (51) has a ram motor (134) and a rotate motor 136) fixed therein and connected to respective gear shafts (36) and (52) extending from the main body (49). A cross slide motor (74) and corresponding shaft (70) are fixed to the motor module (51) but allowed to rotate with rotating apparatus in the main body (49).

A reinstatement cutting machine having an air tube formed therethrough for carrying pressurized air to drive a cutting tool. The air tube is insulated to prevent condensation within the reinstatement cutting machine due to temperature changes caused by the pressurized air passing through the air tube. In a preferred embodiment, the air tube is insulated with a tubular member constructed of an insulating material.

Cutting apparatus having a ram axis gear tube (32) equipped with internal threads engageable with external threads (48) of a main shaft (42). A tool can be fixed to the main shaft (42). The external threads (48) of the main shaft (42) are formed on external splines (44). A main shaft rotation gear (46) has internal splines (41) mating with the external splines (44) of the main shaft (42). Rotation of the ram axis gear tube 32 thus causes the main shaft (42) to move axially via the internal and external threads. Rotation of the main shaft rotation gear (46) causes rotation of the main shaft (42). The tool fixed to the main shaft (42) can thus undergo axial and rotational movements. A motor (74) can be coupled to main shaft (42) and a motor shaft (63) extended through the ram axis gear tube (32) and the main shaft (42). The motor shaft (63) can drive a linear gear (68) of a cross slide assembly (24) and thus radially move a tool fixed to the cross slide assembly (24).
