摘要： A method and apparatus for transient blocking relying on a transient blocking device and a sampling circuit. The transient blocking device has at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device such that a transient alters a bias voltage Vp of the depletion mode p-channel device and a bias voltage Vn of the depletion mode n-channel device in such a manner that the depletion mode devices mutually switch off to block the transient. The sampling circuit is interconnected with the depletion mode p-channel device and the depletion mode n-channel device for unblocking the transient blocking device for to determined whether the transient persists. In the event of a persistent transient, the sampling circuit uses a disconnect element for permanently blocking the transient blocking device. Various types of voltage pinching and disconnect elements, including depletion mode devices of the n-channel and p-channel type can be employed in the sampling circuit to sample the transient and permanently block the transient blocking device.

摘要： A set (50) of laser pulses (52) is employed to sever a conductive link (22) in a memory or other IC chip. The duration of the set (50) is preferably shorter than 1,000 ns; and the pulse width of each laser pulse (52) within the set (50) is preferably within a range of about 0.1 ps to 30 ns. The set (50) can be treated as a single “pulse” by conventional laser positioning systems (62) to perform on-the-fly link removal without stopping whenever the laser system (60) fires a set (50) of laser pulses (52) at each link (22). Conventional IR wavelengths or their harmonics can be employed.

摘要： A workpiece processing system employs a common modular imaged optics assembly and an optional variable beam expander for optically processing multiple laser beams. In one embodiment, a laser and a fixed beam expander cooperate to produce a laser beam that propagates through a beam switching device to produce multiple laser beams that propagate along separate propagation path portions and subsequently merge into a common path portion through an imaged optics assembly and optional variable expander. The beam expander sets the shape of the laser beams in the form of a Gaussian spatial distribution of light energy. The imaged optics assembly shapes the Gaussian spatial distribution of the laser beams to form output beams of uniform spatial distribution. In an alternative embodiment, the beam switching device is removed and the laser beams propagate from separate laser sources associated with separate optional beam expanders.

摘要： A wavelength converter (34) such as a nonlinear crystal has an angle cut exit surface (36) to separate a harmonic wavelength from a fundamental or different harmonic wavelength. A solid optical overlay medium (28) has an entrance surface (38) that is angle cut to mate with the converter exit surface (36). The optical overlay medium (28) is substantially transparent to the fundamental and selected harmonic wavelengths, has a refractive index similar to that of the wavelength converter (34), and has damage thresholds at the selected wavelengths that are greater than the respective damage thresholds of the wavelength converter (34).

摘要： An apparatus and a method for determining wear of a feedscrew and barrel combination includes measuring wear of the barrel using a gage plug in a measuring aperture in the barrel or an ultrasonic thickness gauge and measuring feedscrew wear with an eddy current sensor or a dial indicator mounted in the measuring aperture. A system gathers wear data from various production installations, analyzes the data to predict remaining life of the barrel and the feedscrew and generates an order for replacement parts to be manufactured and shipped just prior to the end of the remaining life.

摘要： An apparatus and method for high-voltage transient blocking employing a transient blocking unit (TBU) that has at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device in concert. Specifically, the bias voltages are altered such that the p-channel device and n-channel device mutually switch off to block the transient. The depletion mode n-channel device employs a set of cascaded low-voltage depletion mode field effect transistors (FETs) such as metal-oxide-silicon field effect transistors (MOSFETs) connected source-to-drain to achieve the desired high-voltage operation of the TBU.
