Granted: 1992-03-10
Abstract: MULTIPROCESSOR MEMORY MANAGEMENT METHOD               AND APPARATUS           Abstract In a multiprocessor system, memory of each adjunct processor comprises global memory and local memory. All global memory is managed by a process manager of host processor. Each processor's local memory is managed by its operating systemkernel. Local memory comprises uncommitted memory not allocated to any process and committed memory allocated to processes. The process manager assigns processes to processors and satisfies their initial memory requirements through global memory allocations. Each kernel satisfies processes' dynamic memory allocation requests from uncommitted memory, and deallocates to uncommitted memory both memory that is dynamically requested to be deallocated and memory of terminatingprocesses. Each processor's kernel and the process manager cooperate to transfermemory between global memory and uncommitted memory to keep the amount of uncommitted memory within a predetermined range.

Abstract: ABSTRACT OF THE DISCLOSURE      A multiple driven axle vehicle, such as a four-wheel drive recreational vehicle having its front, steerable wheels being optionally driven by providing double acting overrunning clutches in the hubs of the front wheels.  Transmission means is pro-vided for driving the front, optionally driven wheels slower than the driving surface otherwise drives those wheels so that the slower driven wheels overrun and do not engage when the steerable wheels are turned as the vehicle is driven through a turn, thereby eliminating the need for a differential between the steerable wheels and between the front and rear wheels.  The overrunning roller clutches of the optionally driven hubs desirably include an intermittent friction apparatus operative between the roller cage and the vehicle chassis to intermittently exert a force tending to retard rotation of the cage with respect to the chassis, thereby indexing the roller cage and rollers to the forward or reverse engagable position.       The intermittent nature of the friction permits the roller cage and rollers to return to the central, neutral position when rotation of the cage with respect to the chassis stops.  The roller clutches further include a generally cylindrical cam driven by the transmission and located radially inward of the rollers and roller cage.  The cam surface includes a ridge associated with at least some of the rollers for inhibiting inertial movement of the rollers from the forward engagable position to the reverse engagable position, as for example during sudden braking.

Title: Ink jet array
Inventor: HOISINGTON PAUL A
IPC: G01D15/16
Filed: 1988-09-06
Granted: 1992-09-01
Abstract: Ink Jet Array Abstract In the representative embodiments of an ink jet array described in the specification, a linear array of ink jet orifices (31-34) is supplied with ink from pressure chambers (35-38) alternately disposed on opposite sides of the array to permit close spacing of the ink jet orifices.  At the end opposite from the ink jet orifice, each pressure chamber (35-38) com-municates with a low acoustic impedance chamber (43-46) to reflect negative pressure pulses from the pres-sure chamber back through the chamber as positive pulses and to prevent pressure pulses from being transmitted to the ink supply.  In addition, a high-impedance passage (47-50) between the low acoustic impedance chamber associated with one pressure chamber and the pressure chamber for the adjacent ink jet provides a continuous flow-through passage from the ink supply port for one ink jet to the ink supply port for an adjacent ink jet.  This permits continuous circulation by thermal convection of the ink when the ink jets are not in use to prevent settling of pigment in a pigmented ink and to transport ink containing dissolved air from the region of the ink jet orifice to a deaeration passage.

Abstract: A MAGNESIUM TITANATE CERAMIC AND DUAL DIELECTRIC SUBSTRATE USING SAME                         Abstract of the Disclosure The average chemical composition of a reaction band at the interface adjacent co-sintered layers of barium titanate and a low K magnesium zinc titanate is bound to be Mg0.5Ba0,25Zn0.25TiO3. That magnesium  barium  zinc  titanate  is  compatible  physically  and chemically with barium titanate when the two are made adjacent in the green state and are themselves subsequently co-sintered. The preferred structure for use as a printed-wiring substrate capable of containing surface and buried capacitors and resistors is a stack having  a barium titanate  layer  sandwiched between  two magnesium barium zinc titanate layers. The ratio of the dielectric constants (K) of the two materials exceeds 100. Thus, there is the possibility for making large value capacitors buried in the high K barium titanate while there is little capacitance and cross-talk between conductors in the outer low K material layers.
