Title: Laminated material and method for manufacturing the same
Inventor: ANDERSSON THORBJORN
IPC: B32B27/00
Filed: 1985-04-15
Granted: 1990-01-23
Abstract: ABSTRACT The invention relates to a laminated material which comp-rises a carrier layer of paper or cardboard and an outside layer of extruded polythene applied to one side of the car-rier layer . To the other side of the carrier layer is applied a first binder layer of polythene and a layer of aluminium foil placed against the binder layer . A second binder layer of EAA is provided for the bonding together of the aluminium foil with an inner polythene layer which has been produced by blowing and which has a substantially higher modulus of elasticity and strength than the slot-extru-ded polythene layer . The invention also relates to a method ~or the manufacture of the laminate by making use of the heat content of the first slot-extruded binder layer of po-lythene for heating up the second binder layer of EAA to such a temperature that an effective bonding on the aluminium foil is obtained.

Granted: 1992-04-14
Abstract: Abstract An improved decoder for a recorder-decoder system wherein a threshold level detector is included in the decoder. The recorder provides for the recording of an audio signal plus a data signal. The data signal includes zero crossing information for sequential increments of time plus an indication of whether the threshold level was met for an increment of the recorded audio. Upon playback the decoder also provides a data signal based on the recorded audio. The threshold level detector of the decoder is higher than that of the recorder. If the recorded data signal indicates the threshold was not met and the same threshold level indication is not provided by the threshold level detector of the decoder for the corresponding increment of the recorded audio signal, tampering of such audio increment of the recorded audio is considered to have occurred.

Abstract: ABSTRACT            An  arrangement  is  used for  the  efficient  mass  production of individual  bodies  for the artificial  rebuilding of teeth,  for example.  The arrangement  comprises a first pair of co-rotating elements,  of which the first element  (1) is so arranged as to support a replica (21) of a body which is to be produced, and the second element (2) is so arranged as to support a blank from which the body is to be produced. The replica and the blank are caused to rotate synchronously about the axis of rotation (3, 4) of the respective element. In a second pair of elements a third element supports a sensing device (31) which is capable of interacting with the external contour of the replica, and a fourth element supports a tool  (52) by means of which the blank is capable of being machined. The first and second pairs of elements are capable of being displaced relative to one another. The fourth element is adjustably connected to the third element (29) in such a way that the tool executes movements which correspond to the shape of the external contour of the replica sensed by the sensing device (31).

Abstract: A METHOD AND APPARATUS FOR ARBITRATION AND     SERIALIZATION IN A MULTIPROCESSOR SYSTEM       ABSTRACT OF THE DISCLOSURE          A  method   and   apparatus   for   providing arbitration  between  and  serialization  of  plural processors in a multiprocessor system comprising, in each processor, a delay network, a priority circuit, a REQUEST generator, an ORDER generator, a serialization program, an ACK generator and an ACK receiver.   In operation,    the   delay   network   insures   that simultaneously generated REQUESTS received from plural processors are received by the priority circuit at the same time.   A processor awarded priority issues an ORDER to the other processors and thereafter drops its REQUEST  to  allow  an  award  of  priority  to  another processor.  An ACK is received by the ORDER issuing processor  from each processor when it executes the ORDER.  The ORDER issuing processor then completes the task  which  gave  rise  to  the  ORDER.   To  conserve processing time, priority awards may be made before previously     issued     ORDERS are     completed.          Alternatively, REQUEST issuing processors can simply hold their REQUEST and thereby prevent interruption of instructions or groups of instructions.

Abstract: 8332-158/53.1094 IMPROVED SCHOTTKY BARRIER DIODE FOR ALPHA PARTICLE RESISTANT             STATIC RANDOM ACCESS MEMORIES        ABSTRACT OF THE DISCLOSURE           An improved Schottky barrier cliode for increasing the alpha particle resistance of static random access memories includes an extra implanted N-type region at the surface of the epitaxial layer to increase the impurity concentration there to about 1x1019 atoms per cubic centimeter.  In one device, arsenic is employed to overcompensate a guard ring where the Schottky diode is to be formed, while in another device phosphorus is employed and the guard ring is not overcompensated.  The resulting Schottky diodes, when employed in the static random access memory cells, dramatically increase the alpha particle resistance of such cells, while also substantially decreasing the access time.

Abstract: ABSTRACT OF THE DISCLOSURE           A joystick device disclosed has a plurality of light emitter-detector devices disposed around a control shaft in a casing supporting the shaft.  A first blocking member on the control shaft selectively blocks out the light to one or two detectors which produces a change in electrical state at an output terminal of a signal processing circuit connected to each detector without the use of any physical contact or the use of mechanically operated electric switches.  A second blocking member on an axially movable inner shaft actuated by a button interrupts the light from another light emitter-light detector device having a similar signal processing circuit.  The output circuit connects to a plug-type connecting member that connects to a load device such as a joystick-operable computer or video game.
