Abstract: A single crystal silicon wafer which, during the heat treatment cycles of essentially any electronic device manufacturing process, will form an ideal, non-uniform depth distribution of oxygen precipitates. The wafer is characterized in that is has a non-uniform distribution of crystal lattice vacancies, the concentration of vacancies in the bulk layer being greater than the concentration of vacancies in the surface layer and the vacancies having a concentration profile in which the peak density of the vacancies is at or near a central plane with the concentration generally decreasing from the position of peak density in the direction of a front, surface of the wafer. In one embodiment, the wafer if further characterized in that it has a first axially symmetric region in which vacancies are the predominant intrinsic point defect and which is substantially free of agglomerated intrinsic point defects, wherein the first axially symmetric region comprises a central axis or has a width of at least about 15 mm. In another embodiment, the wafer is further characterized in that it has an axially symmetric region which is substantially free of agglomerated intrinsic point defects, the axially symmetric region extending radially inwardly from a circumferential edge of the wafer and having a width, as measured from the circumferential edge radially toward a center axis, which is at least about 40% the length of a radius of the wafer.

Title: Accessing data from a multiple entry fully associative cache buffer in a multithread data processing system
Inventor: AVERILL DUANE ARLYN
IPC: G06F12/08
Filed: 1998-11-18
Granted: 2001-10-21
Abstract: A memory cache sequencer circuit manages the operation of a memory cache and cache buffer so as to efficiently forward memory contents being delivered to the memory cache via the cache buffer, to a multithreading processor awaiting return of those memory contents. The sequencer circuit predicts the location of the memory contents that the processor is awaiting, and speculatively forwards memory contents from either the cache buffer or memory cache, while simultaneously verifying that the speculatively forwarded memory contents were correctly forwarded. If the memory contents were incorrectly forwarded, the sequencer circuit issues a signal to the processor receiving the speculatively forwarded memory contents to ignore the forwarded memory contents. This speculative forwarding process may be performed, for example, when a memory access request is received from the processor, or whenever memory contents are delivered to the cache buffer after a cache miss. The sequencer circuit includes a plurality of sequencers, each storing information for managing the return of data in response to one of the potentially multiple misses and resulting cache linefills which can be generated by the multiple threads being executed by the processor. For each thread, there is one designated sequencer, which is managing the most recent cache miss for that thread; the information stored by the designated sequencer is used to predict the location of data for speculative forwarding, subject to subsequent verification based on the information in other sequencers and the cache directory.

Title: System and method for measuring relative and absolute amplitudes of a signal read from a data storage medium
Inventor: PHILPOTT RICK ALLEN
IPC: G11B5/00
Filed: 1999-08-10
Granted: 2002-10-01
Abstract: An apparatus and method for measuring an amplitude of a readback signal obtained from a data storage medium involves transmitting the readback signal to a gain modifying amplifier, such as a variable gain amplifier (VGA), preferably provided in the read channel. A voltage signal associated with a loop gain of the amplification circuitry is sensed and compared with a number of control voltage signals, each of the control voltage signals being associated with a corresponding digital word value. The digital word value associated with a control voltage signal that is equal to the sensed voltage signal represents the relative amplitude of the readback signal. Gain characterization circuitry may further be combined with readback signal amplitude measuring circuitry, preferably in-situ a read channel, to obtain the absolute amplitude of a readback signal. Gain characteristics of the amplification circuitry are determined by applying reference voltage signals associated with corresponding pro-established gain values to the signal input of the gain modifying amplifier. A control voltage signal is selectively applied to the amplifier for each of the reference voltage signals until the amplifier output voltage signal is substantially equal to a pre-established reference voltage signal. Amplitude measurements may thereafter be taken to obtain the absolute amplitude of readback signals. Readback signal amplitude measurements may be performed when the read channel is in a read mode, idle mode, or servo mode of operation.

When the weight of liquid in the reception container reaches the preset value, the weight scaling apparatus passes this signal through the control box to the computer and make computer process in order to give a command of stopping material supplying until the material distribution of reception container is completed, then next operation of automatic measurement will be proceeded.
