Filed:

Sep 30, 1997

Appl. No.:

8/941323

Inventors:

Nurcan Coskun - Austin TX
Kalpesh Jashbhai Patel - Austin TX

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 900
G06F 946

US Classification:

709318

Abstract:

A method and system for efficiently handling events occurring in an environment in a data processing system. The data processing system includes multiple environments and objects that may be used in different environments. Each object includes an action that is triggered in response to an event. An event manager object is created for handling events from different environments. Events are registered for the objects. An action is triggered using the event manager object in response to detecting an event occurring in the data processing system, wherein events occurring in an environment are efficiently handled.

Abstract:

There is provided a scanning laser beam delivery system for use in pulsed laser deposition of a target evaporant (40) onto a substrate (50). The system includes a laser beam source (10) for generating a pulsed laser beam, a beam transfer assembly (20) optically coupled to laser beam source (10) for directing the generated pulse laser beam along an optical path (15) having a terminal segment (15') which impinges upon target evaporant (40); and, a control mechanism (30) coupled to beam transfer assembly (20). Beam transfer assembly (20) includes a scanning mechanism (22) for reversibly translating terminal segment (15') of optical path (15) along a scan direction substantially normal to the direction along which terminal segment (15') has a directional component. Actuation of scanning mechanism (22) is automatically controlled by control mechanism (30).
