Title: Tamper indicating package
IPC: B65D41/34
Filed: 1987-12-03
Abstract: A tamper indicating package (20) comprising a one-piece molded closure (23) of plastic which threads onto a container (21) such that when the closure is unthreaded, a tamper-indicating ring (28) becomes separated from the lower end of the closure skirt. The indicating ring or band (28) is joined to the closure along a weakened frangible line and a flexible stop ring (31) is formed within the band (25) and extends inwardly and upwardly when the closure is applied to a container finish. The container finish (22) has a first radial bead (37), a second radial bead (39) spaced axially below the first bead (36), and an intermediate tapered or concave surface between the first radial bead and second radial bead. A further surface (41) extends from the second bead (39) axially downwardly and radially inwardly and the flexible end of the stop ring (3) rests on this surface between the two beads, when the closure is applied. When the closure is unthreaded to remove it, the free end (32) of the stop ring (31) passes over the second bead (39) into the recess formed by the surface between the two beads and the frangible portion (29) is broken leaving the ring and band in this position. Upon subsequent reapplication of the closure (12), the closure skirt (25) engages the band (28) causing the band to pass over the second bead (39) on the finish so that the band falls away but remains on the container to indicate that the band has been severed.

Title: Circuit for the detection and/or control of synchronisation words comprised in a serial data stream
IPC: H04J3/06
Filed: 1988-08-19
Abstract: In the digital processing of signals, it is important that synchronisation words contained in the serial data stream are reliably detected. In a circuit arrangement for detecting and/or monitoring synchronisation words contained in a serial data stream, a first shift register is provided into which the data stream is continuously written. The storage cells of the shift register are logically combined via a logical AND gate, at the output of which a first detection and monitoring signal occurs. The first shift register is followed by a second shift register into which the data stream read out of the first shift register is written. A first nominal value is loaded into the first part-shift register by the detection signal. The outputs of the first and second shift registers are logically combined by a logic gate at the output of which a second detection and monitoring signal occurs. The circuit arrangement can be applied for detecting synchronisation words in digital audio broadcasting.

Title: Micro-optical building block system and method of making same
IPC: G02B6/28
Filed: 1988-08-30
Abstract: A micro-optical building block system for optical processing of light signals and method for making the components used in the system. The basic system includes a master substrate (31) on which is mounted at least one building block (21-28). Typically, there are a multiplicity of pre-defined positions at which the building blocks will mate with the master substrate. Building blocks can be positioned adjacent to each other on the master substrate in such a way as to allow light signals to be transferred between them. Mating relief patterns (83, 73, 74) are formed on both the master substrate and the building block stubstrates, the relief pattern areas on the master substrate being adjacent and repetitive, or alternatively, different patterns. The mating relief patterns enable self alignment of the building blocks at predetermined positions on the master substrate. The relief pattern on the building blocks is adapted to be employed to embody a variety of optical components as integral or constituent parts of the relief pattern. Alternatively, the relief pattern is used as a mechanical fixture for optical or mechanical components, or both, which define the functions of the building blocks.

Patent EP-0378894-A3 (EP)
IPC: H01L21/20
Filed: 1989-08-24
Abstract: A process for manufacturing selectively doped heterostructure field-­
effect transistors (SDHTs), a desired wafer structure for SDHT fabrication and a 
method for isolating SDHTs on the wafer are disclosed herein. The wafer has 
epitaxial layers grown on a substrate. The layers are: a buffer layer of GaAs, a first 
spacer layer of AlGaAs, a donor layer of AlGaAs, a second spacer layer of AlGaAs, 
a first cap layer of GaAs, an etch-stop layer of AlGaAs and a second cap layer of 
GaAs. A protective layer of AlGaAs may then be grown on the second cap layer to 
protect the second cap layer from contamination or damage. Also a superlattice may 
first be grown on the substrate. Openings are made in the protective layer and then 
in the second cap layer where enhancement type SDHTs are to be formed. The 
remaining protective layer is then etched along with the exposed etch-stop layer with 
a selective etch to expose the first cap layer and the second cap layer where 
respective enhancement-type SDHTs and depletion-type SDHTs are to be formed. 
Gate electrodes for corresponding SDHTs are then formed on the exposed first and 
second cap layers and a subsequent selective dopant implant forms self-aligned 
SDHT structures. Multiple layers of dielectric and metal are then deposited to 
interconnect the SDHTs. The selective etch of the AlGaAs protective layer and the 
etch-stop layer results in consistent threshold voltages of the SDHTs across the 
wafer. The isolation of SDHTs is accomplished in a two step isolation involving 
implanting isolation dopant (e.g., oxygen) into the epitaxial layers.
