Title: Method and system of arbitrating access to the data bus shared by several competing sources
Inventor: HUANG ZHAO-JIA
IPC: G06F13/38
Filed: 1997-11-10
Granted: 1999-12-21
Abstract: This invention provides an arbitration technique for accessing data bus shared by several competing sources. Each competing source is given a weighted priority value, though can be adjusted later, based on the bandwidth requirement of each competing source, and this value will be taken as the initial value. In the arbitration process, each of these weighted priority values is compared against all other requesting sources and the source with the lowest weighted priority value is allowed to gain access to the data bus. The weighted priority value of the selected source is decreased by one in the next round of comparison. A two-stage arbitration system is employed under this invention, in which each and every competing source will be assigned to a certain group. The request of each competing source within the same grouping is sent for the first stage arbitration, from which a source elected by the first stage arbitrator in each grouping is then sent to the second stage arbitrator for further comparison. Again, the source with the lowest weighted priority value is selected in the arbitration process. After the arbitration process has completed, the weighted priority values of all competing sources having sent out bus request will be adjusted accordingly.

Title: Seal for a shaft exiting a housing
Inventor: ORLOWSKI DAVID C
IPC: F16J15/40
Filed: 1998-08-28
Granted: 2000-07-11
Abstract: This invention discloses an improved seal utilizing an air purge to remove contaminants. The seal is most useful on spindles and utilizes a combination locking ring and diffuser ring to diffuse the air within the seal member itself. The pressurized air is passed from the diffuser into at least one cavity or chamber which is within the rotor of the seal and which, because of its rotation as the rotor, provides a centrifuging effect to efficiently and completely remove contaminants, including the liquid or air, and thus preventing the contaminants from reaching the bearings which the seal or bearing isolator is protecting. The bearing isolator or seal element will operate efficiently with or without air pressure, but operates more efficiently with a very small air pressure applied to the diffuser and locking element.

Abstract: A semiconductor device uses externally supply power voltage as its operation voltage. This device consists of multiple memory cells, each includes multiple wordlines and bitlines of cross arrangement. This device also includes an internal power supply voltage generation circuit, which receives the externally supplied power voltage to produce a first level internal power supply voltage. Besides, this device has many wordline drivers; each wordline driver connects the wordline and the power node to receive the internal power voltage. Each wordline driver is used to select the signal according to the wordline and to drive the corresponding wordline in the internal power supply voltage. Whether the external power supply voltage increases or not, the wordline potential of the semiconductor memory device will usually maintain the operation voltage. Also it could prevent the wordline being charged above its requireed potential of external power supply voltage change. The signal oscillation width and writing back time in each wordline will always be maintained. So, this invention will incur little or no power loss during external power supply voltage change.
