Title: System for controlling crystal growth apparatus and melt replenishment system therefor
Inventor: MACKINTOSH BRIAN H
IPC: C30B15/00
Filed: 1991-02-21
Granted: 1997-04-11
Abstract: A control system for controlling the operation of a system for replenishing the melt in the crucible of an apparatus for growing tubular crystalline bodies of a selected material. The melt replenishment system comprises a container for storing solid particles of said selected material and a dispenser for transporting the particles from the container to the crucible. The control system controls the rate at which the dispenser transports particles from the container to the crucible based on the weight of the solid particles stored in the container, the weight of the crystalline body, and the pressure inside the crystalline body. Additionally, the control system may be adapted to control the temperature of the crucible heater of the apparatus. Compensation is provided by this invention for weight measurement errors that are created by pressure fluctuations within the tubular crystalline body.

Abstract: The invention relates to a method for addressing binary data units of a binary data stream and to a use thereof, the claimed method being meant for addressing a binary stream to be recorded, or which was recorded on a storage medium, such as an optical disk. When recording a binary stream, the presentation data is organised as video object units. Said units have different sizes and also variable duration. Access is alowed to any video objects unit in the binary stream and a management address table based on data units (VOBUn) of the binary stream having a constant size is used. The management address table contains for each of said data units a specific delta duration (delta DURn) indicating the time difference between the moment of arrival of the first packet of a data unit and the moment of arrival of the packet which follows immediately the last packet of said data unit. The computation of the target VOBU data unit address includes the following steps: accumulating the delta durations until the given time values are very close to the VOBU data unit address and multiplying the running index of this element by the constant value of the data unit, the value of the address to be accessed directly resulting therefrom.
