Patent DE-3379018-D1 (DE)
Title: Improved time slot arrangements for local area network systems
Inventor: BEAUFOY RAYMOND
IPC: H04L12/413
Filed: 1983-06-15
Granted: 1989-02-23
Abstract: In local area networks (LAN's) which are required to operate in duplex mode it is necessary for the common communication medium to be operated in a t.d.m. manner. Because the LAN has no common equipment, every station is arranged to contain its own control circuitry and crystal controlled clocking system to produce time slot markers. The system is organised so that each time slot comprises an active period for data or speech transmission or contention resolution, followed by a transit period in which the data or speech reaches the destination. Ideally time slot markers occur simultaneously in both stations and for intermediate stations there is a tolerance which reaches a maximum at the midway point of the network communication medium. The multiplexing system arranges that the time slots are packed as closely together as the delay between most separated stations will allow. The near simultaneous occurrance of time slot markers is maintained by all stations whether busy or free by observing the timing of traffic on the communication medium and adjusting the timing of the station time slot marker to occur in the time between data or speech bursts of existing traffic.

Title: Vlsi chemical reactor
Inventor: CADY WAYNE A
IPC: H01L21/68
Filed: 1985-07-23
Granted: 1989-07-20
Abstract: A VLSI chemical reactor includes a fluid flow guide (12) spaced fror- the corresponding substrate (14) in the form of a wafer for significantly reducing contamination in the processing of semiconductor wafers. Processing chemicals are introduced in a continuous process through a central tube and through the fluid flow guide (12) which is substantially planar and which is parallel to the surface (32) of the wafer. A predetermined gap (30) is maintained between the guide (12) and the wafer (14) such that fluid is maintained in the gap (30) at all times critical in the processing of the wafer. In one embodiment, the guide (12) is optically transparent at predetermined portions (110) to permit monitoring of the chemical reaction taking place on the surface (32) of the wafer (14) to permit control of fluid flow to the wafer. Because of the uniform gap (30),the fluid guide (12) insures a constant thickness and composition of the optical path, and thus more accurate measurements. All drying steps are done directly and include the steps of replacing the working fluid with an inert gas and increasing the speed of rotation of either the wafer (14) or the guide (12) to remove any liquid or particulate matter by centrifugal force. Bubble reduction and fluid mixing apparatus, including different fluid guide configurations, gas relief orifices and offset rotational axes, are also described. Moreover, in one embodiment orthogonal and orbital vibrating arrangements are used in lieu of rotating motion.

Abstract: To assist in diagnosing the causes of operating errors which can occur in the operating system a central bus (B:CMY1) has a number of memory blocks (MBOa/MBOb..MB3a/MB3b) forming part of the main memory (CMY). The operating processors (BP,CP,IOC) are connected in parallel to these memories, and have access for read and write to at least one memory block (egMB3a/MB3b). During unoccupied periods the memories, single or in sum, are interrogated at regular intervals, and check against a protocol held in a special memory. At longer intervals, or when a set number of interrogations has been recorded, the results of the protocol checks are printed out. From the interrogations errors in soft or hardware in the operating system, and also under or overdimensioning of operating units can be identified for remedial action.
