Abstract: Particulate deposition rate on a photolithographic mask, particularly of tin (Sn) particles produced within an EUV light source, is reduced by producing turbulence within a radiation source chamber of the EUV light source. Turbulence can be produced by changing the temperature, pressure, and/or gas flow rate within the radiation source chamber. The turbulence reduces the number of particles exiting the EUV light source which could be deposited on the photomask.

Abstract: A safety umbrella includes a top notch member fixed on an upper end of a central shaft and having a resilient tongue which extends downwardly to form a hook end with an actuated shoulder surface. A runner has a slot for retaining the hook end therein at an upper position. An operating sleeve surrounds and is axially movable relative to the runner and has an actuating friction block which is matingly engaged with the actuated shoulder surface at the upper position such that, when the operating sleeve is moved downwardly, the actuated shoulder surface is pressed to withdraw the hook end inwardly so as to disengage the hook end from the slot.

Abstract: A system for linearly transmitting an amplified output signal using predistortion whereby a straight inverse modeling scheme is used to more easily and accurately determine the inverse of the distortion caused by a power amplifier of a RF transmitter. The "inverse" of the power amplifier is directly modeled by considering the power amplifier as a signal processing block with the input and output ports reversed. As a result, the computationally intensive inversion required by conventional schemes is avoided. The predistorter system stores complex coefficients in a predistorter LUT, which are then used as the tap weights of a digital filter implementing the predistorter. The predistortion is done by a non-linear filter which incorporates both instantaneous and average envelope power or magnitude effects. The predistortion LUT is addressed as a function of the instantaneous envelope power or magnitude and past power or magnitude envelopes.

Abstract: A linear transmitter (101) using predistortion includes a modulator (103), a predistorter (107), a digital quadrature modulator (111), an upconverter (113), a power amplifier (115), and an antenna (117). In addition, the transmitter (101) has a feedback loop including a coupler (119), a downconverter (123), a digital quadrature demodulator (125), and a trainer (131). The digital data to be transmitted is provided into the modulator (103), which converts the digital data into in-phase and quadrature component signals. The in-phase and quadrature component signals are then provided to the predistorter (107), which "predistorts" the component signals prior to amplification. The digital quadrature modulator (111) converts the component signals into a single analog signal. The upconverter (113) upconverts this signal from the predistorter (107) into the desired frequency of transmission, which is provided to the power amplifier (115) and the antenna (117) for amplification and broadcast.
