Patent EP-0756024-A2 (EP)
Inventor: HOLDER JOHN D
IPC: C30B29/06
Filed: 1996-06-28
Abstract: A process for preparing a molten silicon melt (16) from polycrystalline silicon for use in producing single crystal silicon by the Czochralski method is disclosed. Polycrystalline silicon is initially loaded into a Czochralski crucible (20), and melted to form a partially melted charge which includes both molten silicon (16) and unmelted polycrystalline silicon (11). The molten silicon (16) has an upper surface (18) above which the unmelted polycrystalline silicon (11) is partially exposed. Granular-polycrystalline silicon (40) is fed onto the exposed unmelted polycrystalline silicon (11) in a manner sufficient to allow the granular-polycrystalline silicon (40) to dehydrogenate while it is resident on the surface of the unmelted polycrystalline silicon (11) and before it becomes immersed in the molten silicon (16). The granular-polycrystalline silicon (40) and the unmelted polycrystalline silicon (11) are then fully melted to form a molten silicon melt (16). The method results in improved zero defect yield, throughput and mean hot cycle times during the production of single crystal silicon ingots.

Abstract: A coded-signal decoding circuit in which, when a signal indicating a transition state from a synchronized state to an asynchronous state is outputted from a synchronous state register (8), data "0" generated by a "0" generating circuit (20) are stored in a data memory (10) instead of an output of an audio signal generating circuit (6), thus initializing the data memory (10) in advance. In a conventional coded-signal decoding circuit, when a transition was made from a synchronized state to an asynchronous state after failing to establish synchronization, the data memory (10) had to be initialized at a point in time before starting the next synchronous detection, presenting a problem in terms of time. The invention further provides a synchronous control method.

Abstract: A method for maintaining memory coherency in a data processing system is disclosed. The data processing system includes a memory system having a dual bus memory controller, which is coupled to a first bus through a first bus master and a second bus coupled to a second bus master. The method maintains memory coherency by snooping across either the first or second bus for attributes on an address/data multiplex bus in the data processing unit. To determine when a snoop operation is required, the system begins by requesting access to either of the two buses through the dual bus memory controller. Once the control of the bus has been granted to upon request data is transferred using the master bus controller. It is upon the receipt of an invalid data signal while transferring data across the bus that the snoop activity begins. The snoop is injected only after an invalid data signal is received and a last snoop injection can occur only before a last read data is read.

Abstract: A method for causing adherence of a web to a drying wire so as to prevent the effects of centrifugal forces and of other air-flow phenomena, which effects attempt to separate the web from the drying wire in dryer groups having a single-wire draw and arranged in a multi-cylinder dryer of a paper machine. The dryer groups include heated drying cylinders, a drying wire for pressing the web against outer cylinder faces of the drying cylinders, and guide cylinders or rolls on which the web runs on the outside face of the drying wire. The guide cylinders have perforations which pass through the cylinder mantle and open into an inside space in the interior of the guide cylinders which is subjected to a vacuum. The vacuum in the guide cylinders is transferred to the outside face through the perforations. The guide cylinders have shafts on which the guide cylinders are mounted revolving. The vacuum level in the guide cylinders is regulated by means of the air quantity in compliance with the threading/running stage and/or running speed and/or with any other process or running parameter of the dryer section of the paper machine so that the effect of the vacuum is sufficient to keep the web in reliable contact with the drying wire.

Abstract: The method involves removing the fluid gas (3) from the container (1). The fluid gas (3) is converted into a gas state. The gas is then returned to the container (1) and the pressure increase in the container (1) is derived. During the pressure increase in the container (1), sound emission signals continually coming from the container (1) are detected. The fluid gas (3) removed from the container (1) is fed to a movable service station (9). In the service station (9) it is evaporated by a heating device (19). The gas is then returned to the container (1) only using the natural gas circulation. While being returned to the container (1), the gas may also undergo condensation by additional heating.

Abstract: A method of lining a pipeline 24 intended to carry gas, oil, water, sewage or chemicals in which a cross-linked polymeric liner pipe 10, which has been reduced from its original diameter to a lesser diameter or to a shape of reduced maximum dimension, is pulled through the pipeline 24. The lesser diameter is less than the least inner diameter of the pipeline 24. After the liner pipe 10 has been fully pulled through, the pipe liner 10 is heated by means of a source 60 of visible or infrared radiation forming part of a pig assembly 50 to cause it to revert to the pipeline. The pig assembly or assemblies are stationary at zones 70 where service connections are to be made. Subsequently, the remaining liner pipe 10 is reverted by pulling the source 60 through the liner pipe 10.

Abstract: Arranging a pair of temperature control units (29, 131, 132, 50) on both sides of gel 1 and arranging light-transmitting slit 134 on one of the elements, irradiation of an excitation beam over the gel 1 and signal detection are practiced through the slit 134. Introducing dry air onto the slit part, mildew occurrence is prevented on the detecting part. Detecting the power level applied to the gel and calculating the temperature of the temperature control units so that the gel temperature might be a predetermined temperature, on the basis of the detected power level, thereafter carrying out the feedback control of the power level, the gel temperature can be controlled appropriately and strictly during electrophoresis in an automatic fluorescent electrophoresis system, so that high-speed analysis can be done highly reproducibly at a higher voltage applied even by SSCP.

Abstract: A gasket for an electrodialysis cell assembly has a series
flow path comprising a plurality of flow path sections joined by
restrictor sections. Each of the flow path sections has a
relatively wide width. The restrictor has less than the wide
width so that a fluid flowing in the series flow path must
increase its velocity as it flows through the restrictor. The
result is that the fluid exiting the restrictor cause turbulence
and agitation in the flow path sections. Manifold holes are
located at opposite ends of the series flow path. A rigid port is
positioned between each of the manifold holes and the ends of the
series flow path. The successive cells of the assembly are
defined by a pair of bipolar membranes with cation and/or anion
exchange membranes between them. One of the gaskets is located
between each two of the membranes.
