US Classification:

Abstract:

The mold described has walls disposed about the mold plates and vent pin retainer plates to permit a vacuum to be generated. The vent pins have been designed to be self cleaning. A pin having a generally cylindrical shape is used. A first portion of the pin has a face defined by a chord of the cylinder. The face leaves a small space between the pin and the opening wall which permits the atmosphere to be removed from the cavity. Below the first portion is a second portion, smaller in diameter than the first portion. Below the second portion is a third portion of essentially the same design as the first portion rotated 45. degree. This portion cleans the walls of the opening when the pin is raised to eject the parts.

Abstract:

A computer system is disclosed that permits multiple write buffer read-arounds. The system comprises a CPU (Central Processing Unit) for executing cycles for the computer system, a cache coupled to the CPU for storing data, a write buffer coupled to the CPU for receiving write data from the CPU, an arbiter to control bus accesses to the slave, and processing signals coupled between the cache and the write buffer for permitting the CPU to read-around the write buffer a plurality of times before the write data in the write buffer is flushed therefrom. The processing signals determine when the data stored in the write buffer is also stored in the cache, and, therefore, the cache is permitted to read-around the write buffer more than one time as long as the write buffer has the same data stored therein as exists in the cache.
