Abstract: A portable spring loaded selector pin device comprising of an automatic release mechanism for use in performing intense weight lifting exercises involving reduced weight lifting sequences on weight lifting machines having weight stacks comprising of a plurality of weight plates. One or more spring loaded selector pin devices may be deployed, allowing the selection of multiple weight reductions to be preset. The spring loaded selector pin device utilizes the friction created by the weight plates to remain engaged while the weight is lifted, and automatically releases immediately after the weight is set down, making the next preset weight ready to be lifted without any interruption in the exercise.

Abstract: Disclosed are optical transmitter and transceiver modules for data communication. Such a transceiver module comprises an array of light emitting diodes mounted on a mounting base (140) being arranged in a regular and symmetrical manner in a dome-shaped housing (142). This housing (142) comprises diffusor means for source enlargement. In addition to the transmitter part consisting of said diodes, the transceiver module comprises a receiver. The receiver has four photodiodes (143) arranged below the mounting base (140). These photodiodes are tilted and face in different directions to receive light from all around the module. The photodiodes are protected by a thin wire mesh (145) which serves as Faraday cage to reduce electro magnetic interference. A substrate (144) for electronic circuitry in SMD-Technology is situated underneath the photodiodes (143).

Abstract: A method for cleaving semiconductor wafers, or segments thereof, which comprises placing the wafer, provided with scribe lines defining the planes where cleaving is to take place, inbetween a pair of flexible transport bands and guiding it around a curved, large radius surface thereby applying a bending moment. With a moment of sufficient magnitude, individual bars are broken off the wafer as this is advanced, the bars having front-and rear-end facets. On cleaving, each bar, while still pressed against the curved surface, is automatically separated whereby mutual damage of the facets of neighboring bars is prevented. For further handling, e.g. for the transport of the bars to an evaporation station for passivation layer deposition, provisions are made to keep the bars separated. Cleaving and the subsequent passivation coating can be carried out in-situ in a vacuum system to prevent facet contamination prior to applying the passivation.

Abstract: Drive arrangement for spinning stations of an OE spinning machine. The feed rollers of the spinning stations can be driven by an electric motor and the draw-off rollers by another electric motor. At least one of these two motors is a synchronous motor. Each of the two motors can be fed supply currents of adjustable frequency by a reverse rectifier, with the rotational speed of one of these two motors being adjusted as a function of the rotational speed of the other motor which is sensed by a pulse generator in such manner that the set rotational speed ratio of these two motors remains constant at operating speeds and in that the operating speeds are ensured even in case of brief network outage.

Abstract: A method and apparatus for breaking a scribed workpiece such as a semiconductor wafer is taught. Briefly stated, the semiconductor wafer is disposed between two elastomeric foils, one of which is adhesively attached to the side of the workpiece which is not scribed. The foils are stretched and a force is then applied to the sandwich so that the workpiece breaks along the scribed lines. Due to the elastomeric nature of the foils the broken pieces separate slightly and remain separated after breaking, thereby preventing damage to adjacent surfaces of the workpiece.
