Inventor: PERLOV ILYA
IPC: C30B25/12

Abstract: A thermal reaction chamber (30) for semiconductor wafer processing operations comprising:
     (i) a susceptor (36) for supporting a semiconductor wafer (38) within the chamber (32) and having a plurality of apertures (70) formed vertically therethrough;   (ii) displacer means (35) for displacing the susceptor (36) vertically between at least a first and a second position;   (iii) a plurality of wafer support elements (66), each of which is suspended to be vertically moveable within said apertures (70) and each of which extends beyond the underside of the susceptor (36); and   (iv) means (64) for restricting the downward movement of the wafer support elements (66). As the susceptor is displaced from its first position through an intermediate position before the second position, the means (64) for restricting operate to stop the continued downward movement of the wafer support elements (66) thereby causing the elements to move vertically upwards with respect to the downwardly moving susceptor (36) and separate the wafer (38) from the susceptor (36).

Abstract: In a color image forming method and apparatus utilizing electrophotography, a toner image bearing film (14) is passed around a photosensitive member (11) and moved past a transfer and fixing device (45), the photosensitive member (11) is uniformly charged, and is then exposed to light images corresponding to different color components of the image. Developing devices (17,19,21) are provided facing the toner image bearing film (14) passing around the photosensitive member (11), and toners of different colors are then made to adhere to the toner image bearing film (14) because of the latent image on the photosensitive member. Thus, the images of color toners are formed on the toner image bearing film (14), and then transferred to a recording paper. The images of color toners may be transferred one by one, or simultaneously. In the latter case, images of the colors, except or including the last-developed one, are temporarily fixed on the toner image bearing film (14), by application of heat, and then transferred to the recording paper (27).

Abstract: Agricultural pneumatic distributors for seed or fertiliser are to ensure that the distribution material is discharged uniformly in a preselected density on an area of farmland, irrespective of whether travelling lanes for a tractor are to be kept free or not or, for other reasons, some of the spreaders connectable to a distributor head (6) of the distributor are not required. For this purpose, there are provided on the distributor head (6) return conduits (6a-6A) which guide excess distribution material either into a feed conduit (5) serving to convey said material, or into a collecting container. The excess distribution material is thereby either returned to the distribution operation or can be brought out of the collecting container into the supply container (1) of the distributor, and the supply container (1), including the metering device and the conveying blower, can be mounted approximately in the front region of a tractor independently of the rest of the distributor. <IMAGE>

Abstract: A multiplexed array of resistors including a plurality of address leads and a plurality of ground leads which cooperatively define a matrix of nodes, each node defining a possible location in the matrix for a resistor heater interconnecting one address lead and one ground lead. Resistor heaters are located in the array at only a portion of the nodes. The locations of the resistor heaters are selected to limit the conductance of alternate current paths around the resistor heater when addressed. The resistor heaters are preferably formed at nodes selected so that no two address leads are interconnected through resistor heaters to more than one common ground lead. Preferably, each alternate current path includes at least four non-addressed resistors in series.

Abstract: An improved method of matching a query string against a plurality of candidate strings replaces a highly computationally intensive string edit distance calculation with a less computationally intensive lower bound estimate. The lower bound estimate of the string edit distance between the two strings is calculated by equalising the lengths of the two strings by adding padding elements to the shorter one. The elements of the strings are then sorted and the substitution costs between corresponding elements are summed.

Abstract: The invention relates to protein thin films and compositions for use in their preparation. In one aspect reverse micelles of protein are used to prepare homogeneous thin films. The process is useful for making thin films of water-soluble proteins which might otherwise be unstable at the air/water interface. In another aspect protein thin films are thermally stabilized whilst preserving the functional properties to produce an oriented Langmuir-Blodgett protein film. Another aspect provides a method for preparing protein thin films on non-planar substrates such as microparticles. Also, in another aspect, the invention provides for chemical functionalization and site-specific mutagenesis of proteins to provide ordered protein thin films.
