摘要： 628,860. Fluid-actuated valves. KNOWLES, J. D. March 3,1948, No. 8176/47. [Class 135] In a float-actuated, cistern supply valve, the valve casing 1 has a valve 13 interposed between the inlet 2 and the. outlet 12, so that the pressure of the water supply helps to maintain the valve 13 on its seat. A float arm 6, pivoted between lugs 5 on the casing 1, has a shorter arm extending into a slot-in the valve 13, which has a conical portion provided with a head 14a and a resilient washer 14. Grooves 16, 17 are provided in the outlet and valve head respectively. The inlet 2 has a restricted passage 9 which may be varied by fitting different nipples 20. The casing 1 has a detachable cap 11 for access to the chamber 10. Water, lead shot or the like may be inserted in the float 8 through a cap 18, or an adjustable weight may be arranged on the arm 6 to vary the buoyancy. A silencer pipe 15 is fitted to the outlet 12. In a modification, the silencer pipe 15, the grooves 16, 17 and the cap 18 are omitted, and the nipple 20 is replaced by a fixed orifice.

摘要： In a thin beam directional Crystallization System configured anneal a silicon layer on a glass substrate uses a special laser beam profile with an intensity peak at one edge. The system is configured to entirely melt a spatially controlled portion of a silicon layer causing lateral crystal growth. By advancing the substrate or laser a certain step size and subjecting the silicon layer to successive “shots” rom the laser, the entire silicon layer is crystallized. The lateral crystal growth creates a protrusion in the center of the melt area. This protrusion must be re-melted. Accordingly, the step size must be such that there is sufficient overlap between successive shots, i.e., melt zones, to ensure the protrusion is melted. This requires the step size to be less than half the beam width. A smaller step size reduces throughput and increases costs. The special laser profile used in accordance with the systems and methods described herein can increase the step size and thereby increase throughput and reduce costs.

摘要： Systems and methods are disclosed for shaping laser light as a line beam for interaction with a film that may have an imperfect, non-planar surface. The system may include a beam stop that defines an edge; a sensor that measures a distance between a selected point on a surface of the film and a reference plane and generates a signal representative of the measured distance; and an actuator coupled to the beam stop and responsive to the signal to move a portion of beam stop edge. Movement of the beam stop edge portion shifts a corresponding portion of the focused line beam in a direction normal to the reference plane to produce a line beam that more closely conforms to the surface profile of the film.
