Abstract: The present invention relates to a method of and an apparatus for manufacturing biaxially oriented film. A tubular original film which has been extruded by an extruding die is biaxially oriented by heat and air injected to the inside portion thereof being conveyed to nip rolls each having an individual circumferential speed. The temperature of heat to be applied to the film is controlled on the basis of the detected film thickness for the purpose of obtaining a uniform film thickness distribution. Furthermore, the film can be made uniform by adjusting the outer diameter of the bubble-shaped oriented film by adjusting the distance between two sets of nip rolls on the basis of the measured width of the film. In addition, when the thus-oriented film is subjected to a heat treatment, temperature of heat is arranged to be a predetermined temperature as to prevent adhesion of the films.

Abstract: In a multiprocessor system including a plurality of cache units which are connected in common to a main storage (20) and to instruction processing units, respectively, each cache unit (3n) comprises a flag circuit (5n) divided into a plurality of flag bit areas (FA-1 to FA-M) which correspond to block areas (BA-1 to BA-M) of a cache memory (4n). Each flag bit area memorizes a flag bit corresponding to a block memorized in the corresponding block area to indicate presence or absence of one of memory blocks in a common memory area of the main storage in correspondence to the memorized block. Supplied with a cache clear request (CRn) from an n-th one (1n) of the instruction processing units, a cache clear circuit (6n) clears the cache memory so as to erase the memorized block when the flag bit indicates presence of the above-mentioned one of the memory blocks in the common memory area. When a block fetching circuit (7n) stores a memory block fetched from the main storage in the cache memory, a fetch detecting circuit (8n) detects whether the fetched memory block is present or absent in the common memory area. When the fetched memory block is present in the common memory area, a flag setting circuit (9n) sets the flag bit indicative of presence in the corresponding flag bit area.

Abstract: A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user. 
     This arrangement can also be used to switch voice packets, using a voice interface such as a digital switch and a digital voice signal to voice packet converter. In accordance with one embodiment of the invention, a packet switch is used for switching voice packet outputs of the data switching modules and a circuit switch, such as the space division switch, is used for switching data packet outputs. In accordance with another embodiment, voice packets are switched from the data switching modules through the space division switch to a small group of data switching modules, which further switch the voice packets through the circuit switch to a destination concentrator.

Abstract: The options of a data processing system are classified into test levels based upon the dependency of the option to other options within a configuration of the processing system. The test level information for each option is stored in a current configuration list of the options. In addition, prerequisite rule bases are linked to each dependent option in the configuration list. The diagnostic system accesses the test level information and the prerequisite rule base information to determine when to test an option, and the order in which to test options, when isolating a failing option. A failing option can be isolated during a system checkout, a selected option checkout, or by resolving a missing option in the current configuration.

Title: DMA Controller performing data transfer by 2-bus cycle transfer manner
Inventor: MIKI YOSHIYUKI
IPC: G06F13/28
Filed: 1990-12-14
Abstract: The DMA controller comprises a data register having a first field and a second field for temporally storing data to be transferred, means for reading data from a data source unit such as a memory (or a peripheral I/O) by executing a read bus cycle to store the read-out data in one of the first and second fields of the data register, and means for writing the data stored in the other of the first and second fields of the data register into a data destination unit such as a peripheral I/O (or a memory) by executing a write bus cycle subsequent to the read bus cycle. Data which have been read from the data source unit and stored in the data register by a preceding read bus cycle executed prior to a current read bus cycle, are then transferred and written into the data destination unit by a write bus cycle subsequent to the current read bus cycle. Therefore, there is no need or providing a time for the arrangement processing of data read out by the read bus cycle and thus it is possible to execute successive operations of a read bus cycle and a write bus cycle.
