摘要： A SiC wafer producing method produces an SiC wafer from a single crystal SiC ingot. The method includes a separation layer forming step of setting a focal point of a pulsed laser beam having a transmission wavelength to single crystal SiC inside the ingot at a predetermined depth from an end surface of the ingot, the predetermined depth corresponding to the thickness of the wafer to be produced, and next applying the pulsed laser beam to the ingot, thereby forming a plurality of modified portions on a c-plane present in the ingot at the predetermined depth and also forming cracks isotropically on the c-plane so as to extend from each modified portion, each modified portion being a region where SiC has been decomposed into Si and C, the modified portions and the cracks constituting a separation layer along which the wafer is to be separated from the ingot.

摘要： System, apparatus and method for opening a heat-bonded connection formed between two hollow, flexible thermoplastic conduits. A pressure difference is created between the inside of at least one of the conduits and the ambient atmosphere sufficient to cause expansion of a wall of the tubing conduit in the vicinity of a frangible portion at least partially blocking the connection to disrupt the frangible portion and reduce the blocking.

摘要： Improved methods and apparatuses for singulating integrated circuit (IC) dies that reduce or eliminate die collisions and work well with very small dies. Embodiments simultaneously separate dies in two dimensions by utilizing a break and expansion system that avoids die collisions by maintaining IC die separation after singulation. Singulation is achieved by placing the joined dies of the wafer substrate on a dicing tape, scoring the wafer substrate between the joined dies, and imposing a bending action by pressing a curved surface against the scored wafer substrate, which also expands the wafer substrate by stretching the dicing tape. After breaking, an inner expansion grip ring is pressed into an outer expansion grip ring in a nested configuration so as to maintain the stretched state of the dicing tape after the curved surface is fully removed, thereby maintaining the dicing tape in tension and the singulated die in spaced apart relation.

摘要： A separation device is usable for separating portions of a material web. The separation device has at least one front clamping device, with at least one front clamping point, and at least one rear clamping device, with at least one rear clamping point, and at least one first stretching element. The separation device can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching device between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point and the at least one rear clamping point, that connection line completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device on the respective same side as one of a transport path provided for the material web and the portions to be separated. The transport line, in the at least one separation mode, is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction and a first transport line, lying on the first reference plane, and a second transport line, lying on the second reference plane, have different lengths when the first stretching element is located in the at least one first separation position.

摘要： A waterjet safety enclosure formed by walls using a detection device or light curtain to detect unsafe conditions. The waterjet safety enclosure walls can be used in new work areas or retrofitted and shaped to fit existing work areas. The waterjet safety enclosure walls may form a partial or complete perimeter about a work area and may be adjustable or mobile. The waterjet safety enclosure wall detects unsafe conditions when a high pressure stream of water from a waterjet cutting machine approaches, contacts or penetrates the waterjet safety enclosure wall. The detection device detects the high pressure stream of water and sends a signal to a controller to stop the operation of the waterjet cutting machine.

摘要： An apparatus and a method distributes printed slips or tickets that are obtained from a continuous strip of material in which the strip is cut by a stationary blade when the user tensions the strip by pulling an end thereof. A driven dragging roller that makes the strip advance in an intermittent manner is interrupted if a sensor detects that the strip is tensioned to be cut.

摘要： The present disclosure relates to processing a substrate including at least one sheet of paper, cardboard or carton by directing a jet stream of liquid nitrogen to a surface of the substrate via a jet nozzle; and by moving the jet nozzle at a distance from the surface. The jet stream can be unmodulated or modulated. For example, the jet stream can be modulated by a modulation unit such as to reduce the impact of the jet stream on the surface. In this way, the jet stream can be applied to score folding lines into the substrate. An unmodulated or on/off modulated jet stream can be applied to cut lines into the substrate. Thus, by applying an appropriate modulation to the jet stream, the processing can switch between cutting the substrate and scoring folding lines into the substrate.

摘要： A hexagonal single crystal wafer is produced from a hexagonal single crystal ingot. A separation start point is formed by setting a focal point of a laser beam inside the ingot at a predetermined depth from the upper surface of the ingot, which depth corresponds to a thickness of the wafer to be produced. The laser beam is applied to the upper surface of the ingot while relatively moving the focal point and the ingot to thereby form a modified layer parallel to the upper surface of the ingot and form cracks extending from the modified layer along a c-plane, thus forming a separation start point. The wafer is separated by immersing the ingot in water and then applying ultrasonic vibration to the ingot, thereby separating a plate-shaped member having a thickness corresponding to the thickness of the wafer from the ingot.

摘要： Apparatus for generating a pulsating pressurized fluid jet are disclosed. One disclosed example includes a line system having at least one nozzle with at least one nozzle orifice from which a pulsating fluid jet of pressurized fluid emerges, and a chamber having a pressure wave generating device to generate fluid pressure waves, where the chamber is in fluid communication with the line system through an outlet opening for the generated fluid pressure waves. The disclosed example also includes a setting device for controlling the amplitude of the fluid pressure waves in the line system upstream of the at least one nozzle orifice where the setting device sets a quotient of a path length of the fluid pressure waves between the outlet opening and the at least one nozzle orifice, and the wavelength of the fluid pressure waves in the line system.
