Abstract: A method forming a bond wire connection includes providing a wire bonder including a bond wedge with a wire guide, and forming a wire bond loop by initially bonding a bond wire to a first bonding surface using the bond wedge, then moving the wire bonder in a loop pattern whereby the bond wire passes through the wire guide, and then bonding the bond wire to a second bonding surface using the bond wedge, wherein moving the wire bonder in the loop pattern comprises a retrograde movement whereby the wire bonder moves away from the second bonding surface, and wherein the wire guide is formed from a material with a higher material hardness than the bond wire.

Abstract: A light source arrangement for a photolithography exposure system comprises at least three light sources with different wavelengths, and a beam splitting unit comprising at least three inputs, one output, and at least two reflecting faces. An input is assigned to each light source and each reflecting face. The reflecting face reflects light that is emitted from the light source assigned to a corresponding input thereof into the output. The three light sources are arranged on three different sides around the beam splitting unit.

Abstract: The invention relates to a method for regulating a light source of a photolithography exposure system which comprises a plurality of LEDs, by means of the following steps: the light output of the individual LEDs in specific wavelength ranges is detected, and the detected light output is compared with a desired light output distribution over the entire spectrum. The LEDs are operated such that the desired spectral light output distribution is achieved in the most precise manner possible. The invention also relates to an exposure assembly for a photolithography device, having a light source which comprises a plurality of LEDs, a control means which controls the electrical power supplied to the individual LEDs, and a sensor which can detect the light output of the LEDs in the respective ranges of the wavelengths.

Abstract: A combined training collar leash for walking, training and otherwise providing the ability to restrain the movement of a dog having an elongated leash with a identical, minor image handle mechanisms disposed at each end of the leash and a locking tab which can slide along the length of the leash and over the handle mechanism and lock in place disposed thereon. When the combined training collar leash is in use, one of the handle mechanisms is placed over a dog's head and around the dog's neck, and then the locking tab is slid over the circular collar to reduce where the circumference of the circular collar to fit snug around the dog's neck. The circular collar of the opposing handle mechanism can be grasped by the user to serve as a handle for the combined training collar leash.

Abstract: In an apparatus for the laser beam exposure of a substrate disc (5), linked block tables (19, 29) are provided, which have each a piezotranslator (24, 31). This makes it possible to perform a fine correction of the movements very rapidly and very precisely.

Abstract: An overlay for a cap bill or visor is disclosed. The overlay is constructed of impermeable, flexible material. On the underside of the overlay is an adhesive covered by a protective film. This protective film is removed and the overlay is placed on top of the cap bill, and the adhesive holds the overlay in place.

Abstract: The invention relates to alignment marks for a process for aligning two objects relative to each other by means of an image recognition system wherein the lines are optoelectronically scanned and the obtained brightness values are integrated line-by-line. The advantages of the alignment marks according to the invention reside in that position inaccuracies due to the mutual optical influence of the alignment marks in the optoelectronic evaluation are avoided and furthermore in a high evaluation speed.

Abstract: In the described optical device a linear object element forms an image by two straight lines crossing each other at a specific angle. Thus it is possible to achieve a crosswise movement of the image point downstream of the optical device with only a single linear scanning movement upstream of the optical device. In particular it is possible to scan plane structures with a single scanning movement.

Abstract: Cathodic protection apparatus employs a grid-type or rod-type anode secured within an electrically insulating tube disposed within an inlet-outlet pipe entering the vessel, the pipe comprising the gross bare area. The vessel is well coated but yet contains minute flaws or bare areas to expose underlying metal, typically steel, to the corroding electrolyte, typically water, contained within the vessel. By maintaining a negative vessel-to-water potential between 0.85 and 1.10 volts as measured between the well coated vessel surface and a saturated copper-copper sulfate reference electrode placed in the water adjacent the coated vessel surface, good corrosion control at the minute flaws is readily effected.
