Abstract: In a method of processing integrated circuits, a polymethyl methacrylate film (40) containing a selected dye and exhibiting a strong dependence on light intensity is photobleached to provide an optical mask to pattern an underlying photoresist layer (20). While the film (40) is photobleached, the underlying photoresists layer (20) is made to be substantially unaffected by the photobleaching process. When the optical mask is realized, it is used to mask the light-sensitive photoresist layer (20) when the photoresist layer is exposed to light. The photobleached layer (40), which is also sensitive to light, is now in turn made to be substantially unaffected by the exposure process. In this manner, the integrity of the optical mask resolution is maintained at its optimum, and densely integrated circuits can be processed and fabricated.

Abstract: A modular synchronizer for use in synchronizing individual signal processors in a multiprocessor system is disclosed. Each synchronizer has a counter for counting its associated processor's clock pulses and, upon reaching a selected count, providing a counter frame output signal at an output thereof for use by each of the other synchronizers in the system. Each synchronizer has a voter responsive to counter output signals from each of the other synchronizers, and from itself as well, at input ports thereof. Each synchronizer's voter provides a frame sync (macro sync) pulse in each counter frame after receiving a selected number of counter frame output signals from any of the synchronizers in the system. Each synchronizer's voted frame sync pulse is provided at an output port of the synchronizer and may be utilized, depending on the application, for routing back into the synchronizer at a frame sync input port for resetting the synchronizer at a frame sync input port for resetting the synchronizer's counter, or for routing to one or more (slave) synchronizers for the same purpose. Each synchronizer's voter includes a rising edge voter that arms a falling edge voter only during a selected portion of the expected counter frame period (voting window). The synchronizer voter architecture can include clocked latches or not. The synchronizer may include fast and slow clock detectors. The synchronizer interfaces with its associated processor and includes disable circuitry for permitting the CPU to disable nonfunctional frame sync signals.

Abstract: The sampling device for chemical, in particular biochemical process technics, consists of a sterilizable container in which a magnetic stirring system is accommodated whose agitator beam may be adjusted in height also in operation. Fluid flows through a tangential inlet near the bottom to be discharged through an outlet provided in the upper end wall. Beneath the filter membrane there is an extremely small dead space through which the filtrate gets to the filtrate outlet. The lower end of the agitator arm is designed as a pointed flow break-away edge which, in case of rotation, generates an alternating pressure field migrating over the membrane. The device is particularly characterized by short response times and by a long service life due to the fact that without a substantial shearing, the filter membrane is kept free from deposits.

Abstract: A method and apparatus for baiting circle hooks includes a baiting station and a surface upon which a piece of bait rests at the baiting station. A groove extends away from the surface. A piece of bait is positioned over the groove. As circle hook is fed to the baiting station the point and point bend of the hook are engaged and hidden by the groove. thus hiding the point of the hook from the bait as the point traverses past the leading edge of the bait. Thereafter, the hook is caused to rotate so that the point impales the bait. Preferably, the hook and bait are thereafter counter-rotated so that the bait piece fully engages the hook and resides on .the hook bend.

Abstract: The invention contemplates controlled ablation of the cornea, using ultraviolet laser radiation, wherein irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation. Sculpturing action results from precharacterized distribution of flus density across the cross-section of laser-beam projection, in the context of beam size, at cornea incidence, to match the area to be ablated, and the duration of exposure determines the extent of curvature change. Illustrative techniques and situations are disclosed, for myopia correction, for hyperopia correction, and for astigmatism correction.

Abstract: An arrangement for the elimination or removal of hydrogen from a hydrogen-containing gas mixture through the intermediary of foils which are fastened within a closable container, wherein the material of the foils produces an elimination of hydrogen, whereby the foils are so arranged at such spacings with respect to each other as to form interspaces between the foils which can be streamed through by the gas mixture. At least one supporting member having the foils adhering thereto is arranged within the container in such a manner that the foils will extend into the surroundings upon opening of the container. Especially suitable for this purpose are spirally-wound supporting members which will extend out of the container under the effect of gravity or under the action of a mechanical spring force, and in this manner provide a direct contact between the effective foil material and the explosively dangerous gas mixture.

Abstract: A packing or unpacking machine having conveyor tracks for articles and containers, with transfer units that are guided in a circular path above these conveyer tracks. Each of the transfer units has a pick-up and carrier head on a support element that can be raised and lowered. A movement mechanism is provided for generating a relative movement for the pick-up and carrier heads relative to the support elements, with this relative movement being superimposed over the rotational movement of the support elements, so that during respective rotation of the support elements, which follow the circular path, the pick-up and carrier heads are moved in a common elliptical or elliptical-like overall path of revolution. In so doing, the respective pick-up and carrier heads are moved about a vertical axis such that a constant parallel position is maintained relative to the conveyer tracks. In this way, not only are the pick-up and carrier heads moved in the transport direction of the conveyer tracks for a period of time that is sufficient to permit reliable pick-up or depositing of the articles, but also a smooth, quiet rotation of the pick-up and carrier heads in the overall path of revolution is achieved.

Abstract: An apparatus for controlling the pressure exerted on a probe in an integrated circuit testing station is disclosed. The apparatus is mounted to a support structure within the station directly above the probe. The testing station further includes lift means for moving an integrated circuit upward against the probe for testing. The invention uses a pressure pad positioned directly above the probe which is attached to the support structure using a resilient member. Associated with the pad is an electrical contact system connected to the lift means. As the lift means moves the circuit upward, it contacts the probe which pushes against the pad. Movement of the probe and circuit against the pad permits secure engagement of the probe with the circuit. As the circuit continues to move upward, the pad is urged upward, causing the electrical contact system to deactivate the lift means before damage to the probe occurs.
