Patent EP-0623824-A1 (EP)
Inventor: GESSNER THOMAS PROF DR
IPC: H01L29/84
Filed: 1993-05-05
Abstract: The high-precision, micromechanical accelerometer is produced as a layered structure made from, in particular, five semiconductor wafers which are insulated with respect to one another by thin semiconductor material oxide layers. The cover plate (1) and baseplate (5) are firstly connected to an assigned insulating plate (2 and 4, respectively) by bonding. Subsequently, counterelectrodes (6, 7) which are fixed on the cover plate and baseplate, respectively, and can be contacted via contact windows (10 and 11, respectively) by the cover plate and baseplate, respectively, are produced from the respective insulating plate by anisotropic etching. A middle wafer (3) contains the unilaterally pivoted mass (14) (pendulum), which is likewise produced by anisotropic etching, and serves at the same time as a movable middle electrode of the differential capacitor. The five-layer structure is hermetically sealed by semiconductor fusion bonding, for example in a vacuum. Electrical contacting of the individual wafer layers is possible from the topside owing to the fact that contact pads (17-21) can be attached for each individual wafer by stepping an edge region of the individual wafers in a staircase fashion. A microaccelerometer according to the invention is distinguished chiefly by extremely low stray capacitances and by high temperature stability. <IMAGE>

Abstract: The instant invention relates to a friction winding shaft, in particular for roll cutting and winding machines with a central drive shaft (8) and fitted, adjoining rings (12) on which tubular winding cores (21) are held under pre-stress via winding core retainers 16. According to the invention, winding core supports (27, 28) which automatically press against the inside winding core surfaces (22) after the start of the winding process to provide firm support are proposed. This provides improved centering and alignment of the winding cores (21). For this purpose each ring (12) is divided concentrically into an inner friction ring (17) and an outer holding ring (18) capable of rotation relative to the former. The inner friction ring (17) is provided with a slanted guide (31, 36) through which a pressure rod (29) or a rotatable support element (32) can be extended into a position of contact against the inside winding core surface (22).

Abstract: An injection-moulding apparatus comprises a mould (3) having a first and a second mould section (5, 7). A bounding surface (13) of the second mould section (7) is in contact with a base (19) of the injection-moulding apparatus. A movable punch (81) for severing a sprue slug from the product and an ejector for ejecting the sprue slug from the punch have been provided in the second mould section. The injection-moulding apparatus further comprises means (93, 99) for moving the punch and the ejector. These means have been arranged externally of the mould inside the base. As a result of this, the mould can be of compact construction and no connection lines for moving the punch and the ejector are required, so that the mould can be removed rapidly from the injection-moulding apparatus. The punch (81) and the ejector (91) have been divided at the location of the bounding surface (113). This enables the second mould section (7) to be coupled rapidly to the base (19), as a result of which the second mould section can be exchanged rapidly with a further mould section.

Abstract: A dialling apparatus comprises a keypad (21) having digit keys for entering a digit corresponding to a set of characters and a function key (SND). Character strings and corresponding digit strings are stored in a memory (23). In response to a digit from the keypad, a controller (20, 24) makes a search through the memory for detecting each one of characters of the set which corresponds to the digit and detecting character strings each containing the detected character. The detected character strings are then sequentially supplied to a display unit (22) from the memory so that they are displayed one at a time. When the command key is operated, the character string being displayed on the display unit is identified and the digits stored in the memory corresponding to the identified character string are dialed to a switched network.

Abstract: A high resolution fast imaging spectrograph is disclosed which provides 400 spatial channels and 100 spectral channels of information. A collimating mirror (10) and a focusing mirror (12) face a plane diffraction grating (14), which is positioned at an acute angle to the perpendicular to the optic axis. An elongated slot (16) is cut through approximately the center of the grating allowing the light source (18) to pass through the slot and onto the collimating mirror. A turning mirror (20), which is placed at the focus of the focusing mirror and adjacent to the slot, directs radiation to a camera mirror (22), which focuses a final image outside the instrument enclosure onto a detector (24). The light source to the instrument is provided by an optical fiber ribbon. The detector will commonly be a CCD or CID 2-D detector, permitting the simultaneous measurement of spectral distribution of a spatial profile. The instrument requires no power input, has no moving parts, and is completely passive with no operating controls or adjustments. Also disclosed is a commercially significant means to utilize the high spatial resolution imaging spectrograph in earth science remote imaging applications through the utilization of a reflecting telescope connected to the spectrograph by means of an optical fiber ribbon.

Abstract: Pour assurer qu'avec un dispositif de protection pour la surveillance et la sécurisation de zones d'accès aux zones à risques d'entrepôts, en particulier pour les entrées d'allées de magasins à rayonnages de grande hauteur, d'une part des véhicules traversant la zone d'accès soient détectés dès leur entrée dans la zone à risques et déclenchent des signaux d'alarme, et, d'autre part, des véhicules passant devant les allées de magasin et les zones d'accès ne provoquent pas le déclenchement d'une alarme, il est proposé de fixer un émetteur de signaux sur ces véhicules. Cet émetteur génére un signal codé en faisceau qui est reçu par un récepteur fixe disposé dans la zone d'accès à l'entrepôt et retransmis vers un dispositif de commande comportant un discriminateur supprimant les signaux de sortie non correctement codés. Il est également proposé que la zone d'accès surveillée soit située à l'extérieur de zones à risques.
