The main focusing lens is formed by at least two focusing electrodes (40,42). The focusing electrode (40) closest to the beam-forming region includes a separated part (52) adjacent to the path of the electron beam. Each separated part forms a portion of a dipole lens structure in the electron beam path. Means (120,122,124) are provided for applying dynamic signals (V b ,V g ,V r ) to the separated parts which are related to the deflection of the electron beams. The dipole lens structures establish electrostatic dipole fields in the path of the three electron beams that cause the beams to converge at the screen for all angles of deflection.

Abstract: The present invention provides a method and apparatus for controlling the fluid flow bias of continuous, multiple zone processes having gas or vapor comprising atmospheres that are in immediate access to each other. Active control of the fluid flow bias in at least one process zone or control of the overall process fluid flow bias is achieved by applying force to at least one of the zones of the process in a manner which enables such control. A physical or chemical property or a change thereof in at least one process atmosphere is monitored and an appropriate amount of force is applied in response to the monitored property. The monitored property is related to the furnace flow bias by an algorithm, so that the flow bias can be controlled by controlling the at least one chemical or physical property monitored.

Abstract: A data base system on a computer uses an index tree containing record keys which reference associated records in the data base. The tree, which comprises a root node extending through intermediate nodes to leaf nodes, provides concurrent accesses to a plurality of users. When changes are to be made to the key structure, action has to be taken to prevent users, other than the user making the change, from corrupting the data or receiving corrupted data. To do this, when one user is inserting or deleting a key and its associated record, all accesses to a node being traversed by this user and the immediately traversed mode are limited to read accesses by other users. At the leaf node, all accesses by others to the key and record being added or deleted are prevented together with accesses to the next successively located record key and its associated record. After the deletion or insertion, the access limitations are removed.
