Abstract: 1277863 Transistors RCA CORPORATION 24 Nov 1970 [20 Feb 1970] 55715/70 Heading H1K A power transistor comprises an annular base region which surrounds part of a collector region of opposite conductivity type at one face of a semi-conductor body. The base region consists of an inner annulus of high resistivity material with a plurality of radial lobes extending therefrom separated by inwardly tapering wedges of low resistivity material which merge into a peripheral ring. A plurality of emitter regions is provided each disposed in one of the lobes. In the embodiment (Fig. 1) a central emitter electrode deposited over a silicon oxide layer on the silicon body contacts all the emitter regions via slots in the oxide, the base electrode overlies the base region ring and has opposed bonding pad extensions on the oxide and the collector electrode is on the back face of the body. Several such structures may be formed side by side in the same body sharing bonding pads to which aluminium connecting wires are bonded. Alternatively the emitter electrodes are thickened to allow face bonding to a substrate with base and emitter connections on different levels. As described the collector region is an N epitaxial layer on an N+ silicon substrate and the two parts of the base and the emitter region formed in successive standard masked diffusion steps, boron nitride being used as the diffusant source for the base region. Electrodes are formed of aluminium by vapour deposition and formetching.

Title: Coating appts. for applying protective wax to cheeses - includes conveyor for partly submerging cheeses in wax and suction lifting devices
IPC: A01J27/02
Filed: 1976-03-26
Abstract: An installation for applying a sealing layer of paraffin wax to the surface of a cheese - includes a wax-filled bath, and a conveyor for transporting the cheeses through the molten wax.

Title: Coating metal surface with protective polymer - using polymer interlayer and local heat excited by electromagnetic radiation and installation for carrying out process
IPC: B05D3/02
Filed: 1977-11-05
Abstract: A protective coating is applied to a metal surface by means of electromagnetic excitation which produces local melting of an intermediate layer of adhesive polymer which bonds the metal to the coating. The coating consists of a polymer which is not melted in the process. The heat is applied by means of an electromagnetic induction coil held above the surface of the coating material and pref. carried in a mobile mounting so that the bonding process can be carried out progressively along the bond interface. The inductor may also be curved to match the profile of the metal surface to be coated, as e.g., in the case of pipe linings. The frequency of the electromagnetic source is pref. in the radio wave band, 200-800 kHz, with a power output equivalent to 25 kW/m of surface to be bonded. The rigid coating polymer is pref. selected from the olefin gp. whilst the bonding material is a synthetic, organic homo- or copolymer with periodic CO gps in the molecular chain. The inductor and source are pref. mounted in a prodn. machine which enables power output, frequency and linear displacement to be remotely controlled in a continuous process. Since the protective coating is not melted, no deformation or crimping occurs during the process.

Patent NL-7908998-A (NL)
IPC: B63B21/56
Filed: 1979-12-13
Abstract: The invention relates to a combination of a pusher tug and one or more barge units, whereby each barge unit may comprise one or more barges coupled alongside each other. Between the barge units and/or between the rear-unit and the pusher tug, pivotable pushing connections are installed giving the combination an articulated character. Each of the pivotable pushing connections is only mounted to one of the units or to the pusher tug and is coupled to the opposite unit with usual connections, such as steel wires.

Patent NL-8901032-A (NL)
IPC: G10L19/018
Filed: 1989-04-25
Abstract: A coder for incorporating extra information in the form of an auxiliary signal in a digital audio signal having a predetermined format as well as a decoder for extracting this extra information from this digital signal, whilst the digital audio signal having the predetermined format is divided into frequency sub-bands, in which on the basis of psychoacoustic qualities of the human auditory system a relatively large amount of quantization noise is permissible, and the samples in each of these sub-bands are quantized relatively coarsely according to a preset criterion, whilst the quantized sub-band signals are summed with samples of the auxiliary signal, whose maximum amplitude is always smaller than a half quantization step of the relevant sample of the main signal; the summed sub-band signals are then reconstructed to a signal covering the entire frequency band, converted into a digital signal having the predetermined format and recorded or transmitted. In an unmodified receiver or reproducing device the original digital audio signal can be reproduced in a conventional way whereas the auxiliary signal remains masked. In a receiver or reproducing device comprising a decoder the signal is again divided into an equal number of frequency sub-hands in a way corresponding to that used in the coder and they are re-quantized according to the criterion applied in the coder. By subtracting per sub-band the quantized signal from the non-quantized signal, sub-bands of the auxiliary signal are formed, which are reconstructed into a replica of the complete original auxiliary signal. The coder can be employed in a device for recording a digital signal on the record carrier. Thus, record carriers can be obtained which are provided with a copy inhibit code and which are thus protected against unauthorized copying. If a signal containing such a copy inhibit code is to be recorded again this inhibit code is detected and recording can be inhibited, the signal to be recorded can be distorted seriously and/or the presence of the copy inhibit code can be signalled.
