Patent EP-0503693-A1 (EP)
Inventor: WANG SU-CHEE SIMON
IPC: H01L21/3063
Filed: 1992-02-17
Abstract: The present invention relates to a method of forming thin bodies of a semiconductor material, such as single crystalline silicon, by selectively etching away a portion of the body until a body of the desired thickness is obtained. The body (18) includes a p-n junction (24) made up of adjacent regions of p-type (22) and n-type (20) conductivity which are immersed in a chemical etchant (14) with the surface (22a) of the p-type region being exposed to the etchant. A time varying voltage waveform having first and second voltage levels is applied through the etchant to the p-n junction. The first voltage level causes a zero forward bias across the p-n junction and the second voltage level causes a reverse bias across the p-n junction. The p-type region is removed by the chemical etchant down to the n-type region. This essentially removes the p-n junction in the area where the p-type region is etched away and resulting current through the n-type region causes a passivating layer (32) to form on the surface of the n-type region which stops further etching.

Abstract: In a data processing system a number of processing nodes share resources. Access to the shared resources is controlled by semaphores, each node having a local copy of all the semaphores. Nodes may acquire ownership of semaphores. When a node requires a semaphore operation on a particular semaphore, a semaphore message is broadcast to all the nodes instructing them to perform the semaphore operation on their local copies of the semaphore. If the semaphore is unowned, the node must suspend the semaphore operation until the message returns, so as to ensure correct chronology for the semaphore operation. If, however, the semaphore owned by this node, the node can perform the semaphore operation without waiting for the message to return. This speeds up the semaphore mechanism. If the semaphore is owned by another node, that other node relinquishes ownership so that the semaphore operation can be performed.

Abstract: In a process for reusing rinsing or cleaning liquid in program-controlled dishwashers or washing-machines, wherein the soiled liquid, which is pumped off out of the washing container at the end of a water-conducting rinsing or washing phase with/without heating of the water, is cleaned, if appropriate temporarily stored, and returned to the washing container in a subsequent rinsing or washing phase, provision is made for a partial quantity of liquid (F1) up to a calculable quantity of residual water (F2) from the available rinsing liquid (S), pumped off from one or more rinsing phases or rinsing programs, to be subjected to filtration for reusing the rinsing water, and for the unfiltered quantity of residual water (F2), remaining at the end of filtration with an increased concentration of the quantity of dirt, to be evaporated, liquified and subsequently added to the filtered rinsing liquid or to be used separately for a subsequent rinsing phase. By means of such a measure, the consumption of fresh water can advantageously be drastically reduced in relation to the previously known water-saving methods without adversely affecting the cleaning performance, and energy-saving operation can be achieved. The heating energy required for evaporating the quantity of residual water is returned to the rinsing water such that virtually no heating energy is lost. The process is also harmless to the environment since only dried filtrate remains from the cleaned rinsing or washing solution, which filtrate can be disposed of without problems in the domestic refuse. <IMAGE>

Abstract: The properties of silicon carbide whisker reinforced aluminium oxide, at present used for cutting tools when machining nickel based alloys, are in a very complex way related to processing and microstructure. important parameters that have been recognized include whisker/platelet distribution, diameter, aspect ratio, surface chemistry and surface morphology. One parameter that has not been discussed is the crystal structure of the silicon carbide phase. Silicon carbide exsist in a mumber of different polytypes, the most common with cubic or hexagonal structure. Available commercial silicon carbide contains mixed hexagonal and cubic silicon carbide-phases or single phase cubic. During sintering it is possible to transform cubic to hexagonal phase by special processing. It is shown that the hexagonal to cubic ratio strongly affects the performance in metal cutting operations and especially toughness behaviour is related to a high hexagonal to cubic ratio.

Title: Apparatus to form a yarn reserve winding
Inventor: RAASCH HANS
IPC: B65H54/34
Filed: 1993-01-09
Abstract: For the further processing of cross-wound bobbins which are wound on textile machines producing cross-wound bobbins, it is advantageous if the yarn end is wound onto the tube at the end face of the bobbin. If the yarn end is not wound tautly onto the tube up to its end, there is the risk that the free yarn end will catch during transport and that the yarn reserve will consequently be drawn off from the tube. In order to fix the yarn end securely to the bobbin, an actuable yarn-guide element (30) is brought to bear against the end face (31) of a cross-wound bobbin (3), in such a way that the yarn end (23) comes to bear on the end face (31) of the cross-wound bobbin (3) and is fixed there for transport. <IMAGE>
