Patent EP-0560043-A2 (EP)
Inventor: ROGNER ARND DR
IPC: B29C67/00
Filed: 1993-02-03
Abstract: In components for waveguide networks, the structures required to guide the optical fibres are low and wide, and the structures for the optical-fibre cable are relatively small. A satisfactory method for producing both structures is unknown to date. Furthermore, there has been no success to date in achieving an exact, cost effective coupling that is stable in the long term of the optical fibres to the structures for the optical-fibre cable. 
<??>According to the invention, the components are obtained by casting by means of a stepped metallic mould insert which, for its part, has been produced, for example, by electroforming from a stepped microstructure member produced by deep X-ray lithography. The components contain webs or trenches as preforms for the optical-fibre cable and further micro-optical elements as well as guide trenches for the optical fibres with a step at the transition between the guide trenches and wave-guiding structure. All the structures are produced simultaneously and in the same way. In order to achieve the optical-fibre cable, the trenches or webs are aftertreated. The fibres are fixed in the guide trenches, for example by means of a casting resin, in a manner which is stable in the long term. 
<??>The components produced comprise, inter alia, couplers, junction boxes, multiplexers and demultiplexers.

IPC: H03M1/14
Filed: 1993-10-01
Abstract: The present invention discloses an improved analog-to-digital converter. A second sampling circuit samples the voltage difference between an analog signal and a reference voltage, before a first sampling circuit moves to a follow operation from a sample operation. Owing to pipelining by the first and second sampling circuits, even after the first sampling circuit moves to a follow operation, the difference between an analog signal and a reference voltage is still applied to a logical-level amplifier. The output of the logical-level amplifier, amplified to a logical voltage, is converted by a logic device into an A/D conversion output. Therefore, ADC differential non linearity error can be reduced.

This embodiment can be applied to other rollers in the wire running system, and adjustment of a position may be carried out manually. Thus, it can be prevented that a wire abuts against only one specific portion of the peripheral face of a roller to form a groove.

IPC: H04Q11/04
Filed: 1995-08-23
Abstract: A facility is provided in an ATM network to control the level of data traffic that a source of data supplies to the network for transmission over an associated connection. Such control is achieved by associating a scout cell with an availability parameter (Ac) and also associating each output port serving a segment of a connection with an availability parameter (Ap) indicative of the level of congestion at the port. Responsive to receipt of a scout cell, an output port overwrites the availability parameter (Ac) contained in the scout cell with its availability parameter (Ap) only if the latter value is less than the former value. The output port then forwards the scout cell to its intended destination. The destination port performs the same function, and then returns the scout cell to its originator via the reverse direction of the connection. Accordingly, the value of the availability parameter Ac contained in a returned scout cell thus indicates whether or not congestion exists at a point along the forward direction of a connection. That is, the value of Ac will be a minimum of all of the port availability parameters (Ap1, Ap2, .... Apn) values that the cell encountered as it traversed the associated connection. The level of such control is then determined as a function of the value of the availability parameter contained in the received scout cell.
