Inventor: STEERE ROBERT E JR
IPC: H01L21/68
Filed: 1990-11-27
Abstract: The wafer alignment fixture (10) is provided with a pair of upstanding walls (18) for mounting of a wafer cassette (11) thereon as well as with a roller (25) parallel to the walls (18) to engage with the wafers (12) of the cassette (11). Rotation of the roller (25) causes the wafers (12) in the cassette (11) to rotate so as to move the notches (13) of the wafers into alignment with the roller (25). Upon coming into alignment with the roller (25), the wafers (12) drop down onto a pair of support surfaces (45) while being spaced from the roller (25) so that further rotation is precluded. The roller (25) may be tensionsed in order to eliminate sag due to the weight of the wafers (12). Also, a second roller (47) may be provided for rotating the aligned notches (13) of the wafers (12) into a different angular position within the cassette (11).

Abstract: The aggregates (7) are brought continuously into a drying and mixing installation (1) at a point at which the binder is injected. The adjustment process consists in measuring the flow in terms of weight of aggregates (T) at a weighing point (11) outside the drying and mixing installation (1). The flow of binder necessary for coating the flow of aggregates measured and the transfer time of the aggregates between the weighing point (11) and the injection point are determined. Finally, injection is effected as a function of the flow and of the transfer time determined. During the startup and shutdown stages of the installation, the determined flow of bituminous binder is injected with a staggering over time greater than the transfer time of the aggregates (7) and in a progressive manner. <IMAGE>

Abstract: A method of conversion of sea-wave energy by means of a wave energy installation, comprising a casing mounted on a floating means (1) in which is located an oscillation generator (2) with counterweights (3) rotatable about their own axle (4). At the lower part of the casing is mounted a stable support (5). The axle (4) with the counterweight (3) is lifted above the floating means (1) at a certain height, dropped together with the counterweight (3) until contact with the support (5) on the floating means (1), thus providing for accumulation of energy by the counter weight (3). Then, during the turn of the counterweight through 180 DEG C about its axle (4) and the subsequent lifting of the axle (4) with the counterweight (3), the energy is recuperated. The free fall of the axle (4) with the counterweight (3) and the turn of the counterweight (3) are effected at the moment of lifting of the floating means on the wave, so that at the moment of the turn of the counterweight (3) the energy accumulated during the free fall of the counterweight (3) is added to the energy of the wave, whereas the lifting of the axle (4) with the counterweight (3) at the required height and placing the counterweight (3) at the initial position is effected during the lowering of the floating means on the wave. When the frequency of oscillations of the floating means (1) on the wave decreases the lifting height of the counterweight (3) is increased and when the former increases the latter is decreased. The invention may be used for production of energy from sea and river waves.

Abstract: On peut éliminer efficacement l'arsenic élément délétère de boues d'hydroxyde de fer, d'abord en soumettant ladite boue à un traitement thermique en présence d'air ou d'oxygène et d'un réactif alcalin, puis par extraction de la matière traitée à l'aide d'eau. L'arsenic présent dans l'extrait est ensuite adsorbé dans un échangeur anionique, élué à l'aide d'un liquide alcalin aqueux et précipité sous forme de sel à partir dudit liquide. La boue résiduelle est plus adaptée pour un réemploi ou pour une application utile. On peut également utiliser le procédé afin d'éliminer d'autres éléments délétères tels que P, Cr, Al, Mn, Zn et analogue, ledit procédé n'étant pas seulement applicable à la boue d'hydroxyde de fer mais aussi à d'autres types de boues ainsi qu'à divers types de matières résiduelles solides.

Abstract: Les dispositifs à cristaux liquides composés décrits permettent d'amplifier les valeurs souvent faibles ou relativement faibles du déplacement directionnel qu'il est possible d'obtenir dans l'axe optique effectif donné par la réponse électroclinique ou ferroélectrique. En choisissant avec soin les directions relatives des axes optiques dans les éléments, on peut effacer partiellement les propriétés chromatiques non désirées, conférant ainsi à la combinaison une chromaticité beaucoup plus petite que celle des cellules simples. Comme applications de ces dispositifs, on trouve par exemple des affichages réfléchissants clairs, des modulateurs, des modulateurs de lumière de type spatial, des déflecteurs et des commutateurs de faisceaux ainsi que des commutateurs de polarisation ou de déphasage capables d'assurer une fonction de commutation entre des étapes binaires ou triples. Des composés d'éléments multiples peuvent alternativement être utilisés pour améliorer la dépendance chromatique, ce qui permet de produire des filtres de couleurs électriquement synchronisables par exemple des filtres pouvant être rapidement balayés entre trois positions dans le diagramme de couleurs CIE.

Abstract: A device for monitoring or checking the closed position of a pivotable door (1), flap or the like, especially of an armoured safe door, or also of another closure of a room or container to be secured is equipped with an actuating member movable as a result of the pivoting of the door (1) and with a switch element loaded by this actuating member. For an installation which can also be carried out at a later date on already existing doors of this type, in which, for example, the pivot bearings (6) can be changed only with great difficulty, if at all, the actuating member is a tension- and pressure-resistant bar (4) which is deflectable or flexible transversely to its longitudinal extension and which is fastened at one end (5) to a fixed part behind the door (1) at a distance from the axis (A) of the pivot mounting (6) of the door (1). The bar (4) extends transversely relative to the orientation of the pivot axis (A) of the door (1) and, as a result of the pivoting of the door (1), is itself deflectable approximately in the same direction as the door (1), its free end (9) opposite the fastening end (5) lagging in relation to the door (1), that is to say executing a relative displacement movement which, during the closing of the door, takes place in the opposite direction and can therefore be utilised for carrying out switching operations. In the closed position of the door (1), therefore, the free end (9) of the bar (4) or a switch pin (16) located there can load a switch (2), a detent (3) or the like and can release it when the door (1) is opened even only at an acute angle, so that this slight opening of the door can be indicated or a closing of the bolt in this position of the door (1) blocked. <IMAGE>

<??>The flexible printed circuit (18) which consists of two insulating layers (19, 20) with a conductive layer (21) located between them and has soldering lands (23) is held by an assembly device (31). The flexible printed circuit (18) is lowered onto the electrical component (12) in the correct position. The lower insulating layer (20) and the conductive layer (21) of the soldering lands (23) which are free of an insulating layer (20) on the top are penetrated by the contact pins (14) which run at right angles to the flexible printed circuit (18). The flexible printed circuit (18) is released from the assembly device (31). A soldered connection (25) is produced between the soldering lands (23) and the contact pins (14). In consequence, an electrically reliably conductive connection can be achieved even in the case of an eccentric allocation of the contact pins (14) to the soldering lands (23).
