Title: Filter or delay line devices employing piezo-electric ceramics
IPC: H03H9/02
Filed: 1971-04-28
Abstract: 1344924 Filters; delay lines SIEMENS AG 28 April 1971 [29 April 1970] 11784/71 Heading H3U  The hard or soft lead-zirconate-titanate ceramic substrate of a filter or delay line device is rendered piezo-electric by an adjustable polarizing voltage applied between two sets, 21, 22 of interdigitated electrodes, producing the polarization field pattern 3. In use, a high frequency field is produced between members of the sets 21, 22 and alternately adds to and subtracts from the polarizing field 3. The resultant transverse deflection produced by coupling between the longitudinal and transverse modes results in the production of Rayleigh surface waves of wavelength equal to the mutual spacing of a pair of electrode fingers. In manufacture, the substrate is metallized and the electrodes formed by photo-etching before polarization. A hard ceramic has a high mechanical "Q", a soft ceramic having a lower "Q" ensuring that the filter or delay line is substantially free of secondary resonances.

Abstract: 1,261,723. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 28 Feb., 1969 [11 March, 1968], No. 11845/68. Heading H1K. In an insulated gate field effect transistor the channel region 30 between the low resistivity source and drain regions 26, 27 contains implanted ions. In the embodiment shown, which is suitable for enhancement mode operation, the channel region 30 is of the same conductivity type as, but of lower resistivity than, the substrate 22, which itself comprises an epitaxial layer on a low resistivity body 21. The source and drain regions each comprise a diffused portion 26, 27 respectively and an ion-implanted portion 28, 29 respectively. The Al gate electrode 35 serves as a mask to define the limits of the portions 28, 29 and hence of the channel. The ion-implanted portions 28, 29 may alternatively be omitted. For depletion mode operation an additional thin ion-implanted layer (37), Fig. 5 (not shown), n-type in the present configuration, is provided at least in the channel region between the source and drain regions. The concentration of ion implantation may vary between the source and drain regions to provide a variable Á device, a particular example involving an increasing ion concentration from the drain to the source. A tetrode IGFET is described in which, between the n-type source and drain regions (46/49, 47/50), Fig. 6 (not shown), an additional low resistivity n-type region (52), termed the virtual source and drain region, is provided by ion implantation. A first insulated gate electrode (58) overlies part of an n-type ion implanted surface layer (48) between the regions (46/49) and (52) to define an nchannel depletion mode part of the tetrode, and a second insulated gate electrode (59) overlies a second surface region between the regions (52) and (47/50) which includes over part of its length a p-type ion implanted portion (54) and over the remainder of its length a further part of the n-type ion implanted layer (48). An integrated circuit embodiment is also described in which a deep n-type island (94), Fig. 7 (not shown), is formed in a p-type substrate (91) by channeling of implanted ions, and an IGFET is formed in this island, e.g. by diffusion of low resistivity source and drain regions (95, 96). A further device, such as a complementary IGFET or a bipolar transistor, is formed in the substrate (91) outside the ion implanted island (94). In all the embodiments Si is the preferred semi-conductor material with silicon oxide and/ or silicon nitride as the gate insulation. Silicon oxide may contain phosphorus ions for stabilization purposes. Phosphorus and boron are referred to as suitable dopants both for diffusion and for ion implantation.

Title: Improvements in refrigerating machines
IPC: F25B31/00
Filed: 1932-04-27
Abstract: 393,065. Lubricating. ROGERS, F. H., 181, Queen Victoria Street, London.-(Getriebebau Ges.; 65, Saalmannstrasse, Reinickendorf - West, Berlin.) April 27, 1932, No. 12133. [Class 12 (iii).] In a compression refrigerating system the lubricating oil, not miscible with the refrigerant, drains to a single collecting point, auxiliary oil circulating means such as pumps being dispensed with. In the arrangement shown in Fig. 1, the oil is delivered with the refrigerant from the condenser 21 to the evaporator vessel 12, approximately at the line between the refrigerant and the oil floating thereon. The refrigerant vapour rises through an apertured tube 15 to the compressor crank case, which forms the suction chamber, and entrains oil with it, and any liquid refrigerant in the crank case passes back to the evaporator through a drain hole 18. The compressor is driven by an overhung electric motor 7 in a removable casing 3 sealed from the crank case by packing 8. A tube 9 filled with granular material connects the motor casing with the oil sump, and serves to drain any oil out of the motor casing. In another arrangement the evaporator forms an unrestricted extension of the crank case and the crank may dip into the floating oil or may be fitted with dipping chains or rings. In a further construction, Fig. 3, the evaporator 24 traversed by tubes 26 is separated by a partition 29 from the crank case, or may be at some distance from it, and the U-shaped vapour suction tube 30 is provided with an enlargement 33 at its lowest part. Lubricant floating on the refrigerant passes through a filter 32 filled with granular material and flows in drops into the widened portion of the suction tube, where the speed of the vapour is reduced so that it cannot entrain an excessive amount of oil. The oil nozzle may be interchangeable to alter the sizes of the drops. Oil flows back from the crank case through a tube 38, which may be straight or, preferably, bent as shown to form a siphon. The arrangement may be employed with lubricant heavier than the refrigerant. Reference has been directed by the Comptroller to Specifications 150,017 and 165,968, [both in Class 29, Cooling &c.].
