Abstract: A contaminant shield (10) prevents airborne contaminants manufacturing facility. The contaminant shield is formed of a plurality of like frames (12), each formed of a plurality of interconnected side frame embers (14,16,18, 20) covered by a flexible sheet attached at its outer edges to the side frame members. The frames are inter­connected at adjacent edges to form the complete contaminant shield. A sealing strip is applied to the joints between adjacent frames to form a continuous contaminant barrier in conjunction with the flexible sheet attached to each frame. The contaminant shield is constructed by first constructing a plurality of frames by interconnecting side frame members into a rigid, planar frame and attaching the edges of a flexible sheet to each side frame member of the frame. Each of the side frame embers includes an aperture which received a complimentrally shaped cap which traps the edges of the flexible sheet between itself and the aperture in the side frame for securely attaching the flexible sheet to the side frame.

Abstract: A DRAM cell with a trench capacitor having a first plate (22,24) formed as a diffusion on the outside surface of a trench and a second plate (field plate 28) formed inside the trench is fabricated. The transfer transistor is in a self-aligned moat area that slightly overlaps the capacitor area and allows for increased misalignment tolerance. The field plate is used as implantation mask for the moat region. It has sloped sidewalls to avoid the formation of conductive filaments from subsequent conductive layers. The bitline contact is self-aligned. 
     In another embodiment, a planar capacitor is used. 
     In a third embodiment two conductive plates are formed inside a trench. 
     A sidewall insulator technique using two selectively etchable materials is used to provide a less destructive fabrication technique for forming sidewall insulating layers and allowing the use of gate insulator layer to protect the surface of the substrate during the formation of the sidewall insulating layers.

Patent EP-0381444-A2 (EP)
Inventor: FITE DAVID B
IPC: G06F9/38
Filed: 1990-01-30
Abstract: A branch prediction is made by searching a cache memory (79) for branch history information associated with a branch instruction. If associated information is not found in the cache, then the branch is predicted based on a predetermined branch bias for the branch instruction's opcode; otherwise, the branch is predicted based upon the associated information from the cache. The associated information in the cache preferably includes a length, displacement, and target address in addition to a prediction bit. If the cache includes associated information predicting that the branch will be taken, the target address from cache is used so long as the associated length and displacement match the length and displacement for the branch instruction; otherwise, the target address must be computed. Therefore, the cache need not be flushed during "context switches" when the computer program is changed. To predict multiple branches simultaneously for a pipelined machine in which instruction decoding, target address computation and branch decision or verification may occur in any order for a respective branch instruction, a sequential state machine (91) is provided having primary states which make predetermined transitions in response to the possible sequences of instruction decoding, target address computation, and branch decision or validation, and markers which store information about the branch predictions made or verified. To further reduce the length of stalls, a cycle in the normal instruction execution is bypassed by the execution unit when resolving the branch direction.

Abstract: Described is a scalable compound instruction set machine and method which provides for processing a set of instructions or program to be executed by a computer to determine statically which instructions may be combined into compound instructions which are executed in parallel by a scalar machine. Such processing looks for classes of instructions that can be executed in parallel without data-dependent or hardware-dependent interlocks. Without regard to their original sequence the individual instructions are combined with one or more other individual instructions to form a compound instruction which eliminates interlocks. Control information is appended to identify information relevant to the execution of the compound instructions. The result is a stream of scalar instructions compounded or grouped together before instruction decode time so that they are already flagged and identified for selective simultaneous parallel execution by execution units. The compounding does not change the object code results and existing programs realize performance improvements while maintaining compatibility with previously implemented systems for which the original set of instructions was provided.

Abstract: 5 n7 An adapter for selectively connecting an external battery which is used as a power source of a portable notebook type computer to the computer or a charger, and an external battery system for controlling the connection between the adapter, the computer and the charger. The external battery is connectable to the adapter, and the adapter is connected to either the charger or the computer. A diode for selectively regulating either the direction for charging the external battery or the direction for introducing the power from the external battery is provided within the adapter. The adapter, the charger and the computer are selectively connected with each other by a common cable. There are three typical connection modes. In the mode A, the charger supplies a power to the computer. If the computer is being operated, the charger directly supplies a power of a constant voltage to the group of devices in the computer. If the computer is in an inoperative state, the charger supplies a power of a constant current for charging the internal battery. In the mode B, the charger charges the external battery through the adapter and outputs a power of a constant current. In the mode C, the power from the external battery is supplied to the computer through the adapter. The external battery is connected to the group of devices in parallel with the internal battery. Both batteries are operated in cooperation with each other. After the external battery is connected to the computer, the computer keeps on operating even if the internal battery is removed. Thus, it is unnecessary to back up the data in the computer.
