摘要： A laser marking system comprises a high power fiber laser consisting of a double clad fiber having a doped core surrounded by an inner pump cladding and providing an optical output for marking; a high power laser diode source for pumping the double clad fiber laser via an input into the inner pump cladding; an optical scanner coupled to receive the marking output from the double clad fiber laser to scan the output over a surface of an article to be marked by sweeping the marking output in one, two or three dimensions to form strokes, the completion of which comprises indicia to be marked the article surface; and a controller to control the operation of the scanner in synchronism with the modulation of the laser diode pump source to initiate the marking output and sweep and modulate the marking optical output in one, two or three dimensions to form strokes comprising the indicia. A main advantage of the fiber laser marking system over CO.sub.2 and YAG laser marking systems is the ability to provide modulation via the semiconductor laser diode at the input to the marking laser rather than having to modulate the optical power beam at the output of the marking laser, such as through an acusto-optic modulator, which provides for a pulse of non-uniform stability across the pulse width with a substantially decrease in the amount of power in the modulated beam output. Also disclosed is circuitry to dampen the ON-time rise of a current signal input for operation of the laser diode pump source to improve the ON-time quality of the marking optical output created by the double clad fiber marking laser.

摘要： A thermally balanced leadless microelectronic circuit chip carrier in which the chip is mounted directly on a heat sinking member by means of a conductive stress relieving polyimide. The heat sinking member, which has a support surface for the chip and an extending threaded shaft, is held by a carrier member thermally compatible with the surface on which the package is to be used. The shaft passes through the carrier member and receiving surface to a heat sinking nut which holds the package to the receiving surface. Leads on the carrier member surface are used to connect the receiving surface to the wires bonded to the chip contacts.

摘要： Laser beam or pulsed output is provided for enhancing the bonding strength between surfaces that are secured together, such as by lamination process or an adhesive, by texturing with a plurality of indentations formed in at least one of the surfaces to be bonded. As an example of this texturing, a fiber gain medium texturing system having a modulated pump or seed semiconductor laser source may be employed for forming a plurality of indentations in the surface of a die attachment pad of a semiconductor die or IC chip carrier. The indentations may be in the form of dimples or grooves. The indentations enhance the bonding strength formed between the chip and the die attachment pad using a die attaching adhesive. Also, the indentations in the die attachment pad provide a way for containment of rapidly expanding gases that formed in the chip carrier package when the package is subjected to high temperatures such as during a solder reflow operation.

摘要： The invention includes systems and methods for debugging an application program running under an operating system such as Windows.RTM. 3.0 or 3.1. Such an operating system allows registration of callback functions with an operating system exception handler. The operating system exception handler calls the registered callback functions in response to an exception generated by the application program until one of the callback functions indicates that the exception has been resolved. The invention includes a monitor program which is installed in program memory concurrently with the application program. The monitor program registers itself with the operating system exception handler to be called in response to an exception generated by the application program. When called, the monitor callback function finds the startup parameters of the application program which generated the exception and starts a debugging program, using the startup parameters. The debugging program, in accordance with normal characteristics of debugging programs, registers itself with the operating system exception handler and then yields to the operating system. The monitor program returns control to the operating system without indicating that the exception has been resolved. Thereafter, the exception handler calls the registered debugging program to initiate debugging of the application program which generated the exception.
摘要翻译：本发明包括用于调试在诸如Windows TM 3.0或3.1之类的操作系统下运行的应用程序的系统和方法。这样的操作系统允许回调函数与操作系统异常处理程序的注册。操作系统异常处理程序响应于应用程序生成的异常，调用注册的回调函数，直到其中一个回调函数指示异常已被解析为止。本发明包括与应用程序同时安装在程序存储器中的监视程序。监视器程序自动注册要响应于应用程序生成的异常而被调用的操作系统异常处理程序。当调用时，监视器回调函数查找生成异常的应用程序的启动参数，并使用启动参数启动调试程序。调试程序根据调试程序的正常特性，对操作系统异常处理程序进行自身注册，然后向操作系统提供。监视程序将控制权返回到操作系统，而不指示异常已被解决。此后，异常处理程序调用注册的调试程序来启动生成异常的应用程序的调试。
