Abstract: A well tap for a field effect device formed using a single polysilicon process and a silicide layer is provided. The polysilicon layer which makes contact to the well is doped the same way as the well but is doped opposite of the source or drain. The silicide layer is formed on the upper and sidewall surfaces of the source or drain, well tap, and gate contacts for a field effect device. The silicide layer extends from the sidewall silicide across the upper surface of the transistors and up to the sidewall oxide of the transistor gates. The structure makes it possible to eliminate laterally-spaced separate well taps used in previous devices. Elimination of the laterally-spaced well taps permits higher packing density, and lowers buried layer-to-substrate capacitance.

Abstract: 2.1. Harvesters possess, for the return of crops into the cleaning process (transfer), a conveyor (46) which delivers the conveyed material at a specific point through an orifice (60) above a threshing unit. When the harvester assumes a lateral inclination, the crop accumulates to an increased extent on the screen device on the downhill side, where it is intercepted, some of it without being cleaned, and fed to the conveyor (46). As a result of this inclination, the crop now returned falls once again onto the downhill side, and therefore a closed circuit with an ever increasing quantity of crop to be returned is obtained. 2.2. It is proposed to change the conveyor (46) in such a way that the delivery of the returned crop can take place in different directions, so that it can be diverted from the downhill side to the uphill side. This solution is achieved in that the orifice (60) in the housing (48) of the conveyor (46) is followed downstream by a guide device (54) for the purpose of feeding the conveyed material to the uphill side in each case. 2.3. A conveyor (46) of this type is used in combine harvesters. <IMAGE>

Abstract: A ceramic composition for forming a ceramic dielectric body having a dielectric constant of less than about 4.6. The composition comprises a mixture of finely divided particles of 35-55 vol.% borosilicate glass and 45-65 vol.% cordierite. The exact particle size ratio of the cordierite to borosilicate glass that is used will depend on the proportions of the components, the desired fired density and the firing temperature. The composition can be used with a polymeric binder to produce an unfired green tape which is co-fireable with high conductivity metallurgies such as gold, silver and silver/palladium.

Abstract: The mechanism 204 prevents reversal on the torque of shaft 203 by braking two disc members 206, 207 against braking surfaces of a casing 205. Under normal operating conditions the member 206 is turned by a motor 202 controlling a load 200 in a direction which causes its drive to be transmitted through balls 221 to the member 207. In this condition minimal braking occurs. If the direction of the shaft 203 is reversed, the balls 221 force apart contiguous camming surfaces on the disc members so that their braking surfaces engage the casing to brake the shaft 203. Controlled manual release of the load under braked conditions is permitted by turning a handle 224 driving a shaft 210 which turns the member 207. Minimal braking friction during normal operations is reduced still further by creating a cushion of oil between the braking surfaces, the oil being provided by a gear pump 216 driven off the shaft 210. The braking surfaces on the casing are referenced 208, 209 and are borne upon by complementary rim surfaces of the disc members 206, 207.

Abstract: A carbonation system (10) is provided in which replenishment or recharging of the carbonation tank (12) is undertaken upon the basis of sensing and monitoring the CO₂ gas head pressure within the tank. No floats or liquid level sensors are employed. A pressure switch (40), monitoring the head pressure within the tank, is operative to turn a high pressure motor (26) on and off to appropriately introduce water into the carbonation tank as the need is dictated by changes in the pressure head. Such changes are an indication of either dispensing of soda, or the absorption of the CO₂ gas into the soda within the tank, both conditions indicating a need for replenishment of water into the soda tank. The addition of water to the carbonation tank may proceed as a function of pressure within the tank, as a function of the time period of a dispensing cycle, or as a combination of time and pressure.

Abstract: Anti-idiotypic antibodies that mimic tumor necrosis factor (TNF) activity. The antibodies may be raised in one species (e.g. a rabbit) using a monoclonal anti-TNF antibody from another species (e.g. a mouse) as an immunogen. Such anti-idiotypic antibodies were cytotoxic to TNF-sensitive cell lines. The cytotoxic activity of the anti-idiotypic antibodies can be neutralized by antibodies that bind to TNF. The anti-idiotypic antibodies may be useful themselves as TNT antagonists or as TNF agonists, and may also be the basis for a new group of TNF agonists or antagonists.

Abstract: An apparatus for displaying a three-dimensional image of a plurality of tomographic images by storing pictorial information of a tomographic image in an image converting element (6), forming interference fringes between a reading light beam (D) which is transmitted through the image converting element and is modulated (2) in accordance with the pictorial information stored therein and a reference light beam (E), and recording the interference fringes on a photographic plate (16). The above operation is repeated for successive tomographic images and then the photographic image is developed to form a hologram of superimposed tomographic images. A three-dimensional image is reproduced by projecting the reference light beam onto the thus developed photographic plate. According to the invention, the image converting element is formed by a Pockels readout optical modulator (6) and an intensity and position of a coherent light beam is modulated in accordance with the pictorial information of the tomographic image. The thus modulated coherent reading light beam is made incident upon the Pockels readout optical modulator. The coherent writing light beam having a high intensity is modulated in accordance with the pictorial information, so that the tomographic image stored in the Pockels readout optical modulator (6) has high contrast and resolution and therefore, it is possible to reproduce a three-dimensional image having very high resolution and contrast.

Abstract: It is proposed to manufacture a phosphor layer by anisotropic (vacuum) evaporation, and in so doing to induce selective structural warps or trenches (grooves, moats) in the phosphor layer. For this purpose, an elastic layer with a pattern of grooves which corresponds to a desired pattern of structural gaps in the phosphor layer is provided above the substrate. Different coefficients of thermal expansion for the phosphor and substrate lead to intensified contraction of the phosphor layer, which is interrupted at the warps, giving rise to areas of the layer (islands) which are completely separate from one another. The phosphor layer is suitable for manufacturing an X-ray detector of high spatial resolution. <IMAGE>

In one example of such a sensor, a pendulum (1) has a coil (3) thereon which interacts with the magnetic field of a magnet (2) on a casing (10) supporting the pendulum (1). A current is supplied to the coil (3) such as to generate a force resisting movement of the pendulum (1).
