Abstract: Excellent stabilization to bright sunlight, is ob­tained in polypropylene (PP) fibers pigmented with Red 144, by combining the pigment with N-(substituted)-1-­(piperazin-2-one alkyl)-α-(3,5-dialkyl-4-hydroxyphenyl)-­α,α-substituted acetamide ("3,5-DHPZNA" for brevity). Stab­ilization of the red color is obtained for as long as the PP fibers themselves are stabilized by the 3,5-DHPZNA. With 3,5-DHPZNA and Red 144 pigment, essentially no secondary stabilizer is necessary. Red PP fibers so stabilized, exhibit an acceptably low level of discoloration (color faidng) due to degradation of the pigment, over the useful life of the PP fibers.

Abstract: A silicon nitride film (36) is used as a passivation film for an ultraviolet erasable non-­volatile semiconductor memory appartus, such as an EPROM. The nitride film has a large stress that is to act on an underlying layer, so that if the underlying layer is a metal inter connection layer (32A, 32B) made of aluminum or the like, it is likely to be destroyed quenched. Therefore, an insulating film, such as a PSG film or silicon oxide film, is formed between the nitride film (36) and metal inter connection layer (32A, 32B) to reduce the stress of the former film (36) acting on the latter (32A, 32B). The nitride film (36) is formed by a plasma method can reduce the growth tempera­ture to approximately 350 to 400°C, which prevents destruction of the metal line layer pattern.

Abstract: When an adaptation request arrives in the form of an adjustment to a manipulated variable or a set point, the resultant settling processes of manipulated variable and controlled variable are sensed and stored. The manipulated variables are supplied to a model (MD), the parameters T,n of which are modified in such a manner that the simulated response of the model excited with the stored variation of the manipulated variable corresponds as closely as possible to the stored real process response. The parameters of a controller (RG) are corrected, for example in accordance with the principle of the optimum of the absolute value, on the basis of the model which has thus been approximated to the process. The invention is used in adaptive controllers. <IMAGE>

Abstract: A method for arbitrating access by a plurality of agents (10,11,12,13) to a bus (1) utilizes a priority access list. Each agent (10,11,12,13) in the plurality of agents (10,11,12,13) has a position on the priority access list. This position indicates the agent's relative priority level of access to the bus (1). When at least one agent (10,11,12,13) from the plurality of agents (10,11,12,13) requests access to the bus (1), bus access is granted to the agent (10,11,12,13) among the requesting agents (10,11,12,13) which is highest on the priority access list. Once an agent (10,11,12,13) from the plurality of agents (10,11,12,13) has gained access to the bus (1), the agent (10,11,12,13) which gained access to the bus (1) is moved to the bottom of the priority access list.

Abstract: Apparatus and accompanying methods, particularly suited for use in conjunction with pipelined instruction processing occurring in a processor of a reduced instruction set computer (RISC), for generating an address during a decode cycle of the instruction processing. Use of this technique substantially eliminates a wait state frequently caused by an address generation cycle that otherwise occurs during pipelined processing of RISC instructions and thereby advantageously increases the processing speed of the RISC processor. In particular, a RISC instruction is both fully decoded and pre-decoded in parallel. The pre-decoding is used to extract the displacement field from the instruction, select a proper base address for the current RISC instruction and, in conjunction with formatting operations, properly align the displacement field - all within the current decode cycle. The base and aligned displacement addresses are then applied to separate inputs of an address adder. The output of the adder is propagated through an address register to an output as a memory address during the decode cycle in the event the full instruction decoding confirms that the current RISC instruction does require an address to be calculated; otherwise, the calculated address produced by the adder during this decode cycle is merely discarded by being over-written during a decode cycle for a subsequent RISC instruction.

Abstract: For a resilient pressure contact, in which a contact head is moved axially against the force of a compression spring on resting against a fixed contact inside a guide sleeve, the object exists of improving the life of the resilient pressure contacts, increasing the reliability by reducing the braided conductor fractures, increasing the current capacity and reducing the overall manual production costs. This is achieved in that a part of the contact head (2a) is constructed on the side facing away from the contact pieces (1) as a hollow cylinder (8) having a wall which has multiple slots (9) radially with respect to the longitudinal axis, the remaining wall sectors being used as current-carrying resilient contact tongues (10) opposite the guide sleeve (3). Braided conductors are no longer used.   <IMAGE>

Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first sub-area (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to access the bad sector are redirected (i.e., revectored) to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted.
