Title: Hierarchical integrated circuit cache memory
Inventor: HETHERINGTON RICKY C
IPC: G06F12/08
Filed: 1991-05-29
Granted: 1997-04-01
Abstract: A hierarchical cache memory includes a high-speed primary cache memory and a lower speed secondary cache memory of greater storage capacity than the primary cache memory.  To manage a huge number of data lines interconnecting the primary and secondary cache memories, the hierarchical cache memory is integrated on a plurality of integrated circuits, each of which includes a portion of the primary cache memory, a portion of the secondary cache memory, and data path circuits interconnecting the portions of the primary and secondary memories to portions of a data processor port and a main memory port.  The primary cache memory, for example, includes ECL memory elements, and the secondary cache memory includes CMOS memory elements.  In a preferred construction, the primary cache memory has address input lines wired in parallel to address input lines of the secondary cache memory, and data input lines wired in parallel to data input lines of the secondary cache memory.  The data input lines of the cache memories are connected to data output lines of a parallel/serial shift register having a parallel input connected to data output lines of the secondary cache memory, and a serial data input connected to the main memory port.  For write-back of data, the serial/parallel shift register includes an additional parallel input connected to data output lines of the primary cache memory, and an additional parallel input connected to the data processor port.

Granted: 1997-02-04
Abstract: In the representative embodiments of the inven-tion described herein, a transducer (25) for an ink jet system includes a piezoelectric element (26) with an array of spaced interdigitated electrodes (12,13) on one side of the element.  One embodiment includes two such arrays (27) disposed near the sides of the ink jet chamber and another array (28) of interdigi-tated electrodes (12,13) on the opposite side of the transducer in the central region of the ink jet cham-ber (20).

Abstract: BRACE FOR PROPANE GAS CYLINDER LIQUID LINE   ABSTRACT OF THE DISCLOSURE     An improved aluminum propane gas cylinder with a braced liquid line or pipe.   The brace is welded to a joggle formed in the rim of the cylinder top head section, and includes a pair of tines which are crimped around the liquid pipe to secure it against vibration.  Securing the brace to the top head joggle permits assembly of the liquid pipe to the brace before joining the top and bottom head sections, and complies with regulations against welding to the straight surface of the cylinder.  With the liquid line braced in this manner, the susceptability of the liquid line to fatigue cracking is substantially reduced.

Abstract: A beverage package has a sealed container 1 cantaining beer 11 having gas in solution and forming a headspace 16 containing gas at pressure greater than atmospheric.        A hollow insert 7 is located in the container and is responsive to a pressure differential developed on opening the top 5 of the container to inject beer and/or gas therefrom with the beer 11 to liberate gas 17 from solution and form froth in the headspace 16.        A baffle plate 12 on the insert 7 restrains the liberation of gas 17 to a minor proportion of the volume of beer 11 so that when the beer is poured into a glass, gas can evolve naturally from the beer to produce "sparkle".        As an alternative to the beer and/or gas injection bubble initiation, gas from solution in the minor proportion of the volume of beer may be liberated by contact of that beer with a bubble initiating material.
