摘要： A circuit arrangement for channel-specific processing of a multi-channel input signal which may consist of two types of encoded signals, a first type wherein all channel signals are encoded by a bit-oriented method (e.g., delta modulation) and a second type wherein all channel signals are encoded by a character-oriented method (e.g., PCM). An interface process (SSP), to which the input signal is applied, is coupled to a bidirectional interface (BIS) for signals of the first type and which is controllable by means of write and read addresses, and is also coupled to at least two such bidirectionally controllable interfaces (BI0, BI1, . . . BI7) for signals of the second type. The latter interfaces are respectively coupled to respective transcoder processors (AP0, AP1, . . . AP7). One or more data outputs of the interface (BIS) for signals of the first type are respectively coupled to respective ones of the transcoder processors (AP0, AP1, . . . AP7). The transcoded channel signals produced by such processors are transmitted via the interfaces (BIS, BI0, . . . BI7) to the interface processor (SSP), which combines them into a multi-channel output signal.

摘要： A system for mounting VLSI devices on a substrate is disclosed, offering a high contact density. Each package consists of a semiconductor device having protruding elongated contact pin (2) on its surface and a wiring substrate having a cavity (3) on its surface. The cavities are filed with a conductive material (7) of a low melting point composition and sealed with a thin non-conductive foil (4). During packaging, the contact pins are made to penetrate the foil, and extend into the conductive alloy, thus making electrical contact therewith. To ease the penetration of the foil, the contact pins could be set into oscillating motion by means of an ultrasonic generator.

摘要： The X-ray sheet film cassette has a top part hinged to a base part. The bottom of the base part is provided with a frame enclosing a film supporting plate through which the radiation is transmitted. The supporting plate has a laminated structure including two face plates of thermoplastically bonded carbon fibers and a comparatively thicker intermediate plate of a synthetic hard foam rubber sandwiched between the face plates and being glued thereto. The face plates are considerably thinner than the intermediate plate in the laminated supporting plate of the present invention.
