Patent EP-0290128-A2 (EP)
Inventor: HARRIS CLARK E
IPC: G01S7/493
Filed: 1988-03-24
Abstract: In an interferometer (10) for transmitting a laser beam toward a target, portions of the transmitted beam reflected by the target are directed onto a detecting surface (25) of a detector element (24) with a local oscillator beam to provide a beat frequency signal representative of, for example, target range. A first lens (22) focuses the target-reflected return beam onto substantially a point (23) on a detecting surface (25). A second lens (30) focuses the local oscillator beam through a focal point (31) onto the first lens (22). The first and second lens (22,30) are so disposed that this focal point (31) of the second lens (30) is coincident with a focal point of the first lens (22) so that the local oscillator beam directed onto the detecting surface (25) of the detector element (24) is incident thereon with a substantially uniform intensity distribution. The detector element (24) can then be implemented as a photoconductive detector which can be cooled be thermoelectric stacks (29).

Abstract: A process of three-dimensional iterative modeling where input data in the form of such as seismic time sections, related interval velocity information and seismic line loca­tion data are used to generate a three-dimensional depth-­velocity model whose computed time response is compatible with the seismic data. The process functions to compare synthetic time sections with original data and then iterati­vely changing the model until the synthetic data is suf­ficiently close to the real data. Layers in the depth model are defined by gridded depth maps, velocity information is specified for each layer, and the time response of the model is computed by raytracing.

Abstract: Discriminating means (D S ,D R ) are coupled to receive signals from a protected transmission circuit (2). The discriminating means (D S , D R ), also receives from a directional detector (DD) signals indicating whether any fault which occurs is forward of, or reverse of, a predetermined point. The discriminating means is arranged to produce an output signal (T S ,T R ) to trip a circuit breaker (4) of the protected circuit (2) only if a fault occurs within the protected circuit (2). In this respect, the discriminating means (D S ,D R ) only outputs a trip signal if it receives within the same time period both a signal from the directional detector indicating that the fault is appropriately located, and high frequency signals from the protected circuit (2). Thus the invention utilises the high frequency noise invariably generated when faults arise in transmission systems. 
     The invention has the advantage that it provides good discrimination of faults without requiring   communication links between discriminating means at each end of a protected circuit, as has previously been necessary.

Abstract: The present invention relates to a method and apparatus for mono-crystalline growth of a dissociative compound semiconductor. The method, which is based on the Czochralski method, includes the following steps. First, a first volatile component material and second material of the dissociative compound semiconductor are prepared. The first material is placed on the bottom of an inner air-­tight vessel which is contained in an outer air-tight vessel. The second material is contained in a crucible supported in the inner vessel by a lower shaft extending from the inside to the outside of the inner vessel. The first material is, next, heated for evaporating so as to react with the second material. Therefore, the dissociative compound semiconductor is synthesized in the crucible. Then, temperature of a furnace installed on the inner vessel is adjusted so that the pressure of the gas of the first volatile component material in the inner vessel is controlled. A single crystal is pulled up from the melt by an upper shaft extending from inside to outside of the inner vessel, thereby the single crystal is grown. The improvement is that the pulling-up step includes the steps of: measuring the weight of the growing crystal, the weight influenced by a difference between the interior pressure of the inner vessel and a pressure outside of the inner vessel; correcting the measured weight of the crystal for the error due to the pressure difference, thereby obtaining an accurate estimate of the weight of the crystal; and controlling a diameter of the growing crystal   on the basis of the weight estimate of the crystal.

Abstract: This invention relates to a technique and system (34) for clustering a set of data points (18) in a data field. Clustering is performed by a set of rules which make no assumptions about the data fields. That is, the number of clusters, the distance between clusters, etc., need not be specified in advance. The invention calculates a distance R that is a function of the distances between each pair of points (18) in a data field. Operating on a chosen point, a parameter is calculated for each neighboring point within distance R from the chosen point. This parameter is proportional to the distance of the neighboring point to the chosen point. The chosen point P is then connected to a neighboring point on the basis of this parameter. All points, in any order are operating on as the new chosen point, so that the additional points may be linked to new chosen points in a similar manner. In this way, a tree-structure (22, 24) of connected points will form the desired clustering. Points (18) not having other points within distance R will not be clustered or linked.
