Abstract: In this invention, an original image is read to be formed as a contour bit map, and the bit map is read out for each plurality of picture elements. Then, in the position to which the aforementioned unit of plurality of picture elements corresponds on the original image, a predetermined bit map data is to be written by a logical sum. If the operation is indicated as a shadowing process, a bit map of a predetermined oblique line for a shadow designated by a direction and a length is to be written. The aforementioned operation is carried out for every plurality of picture elements on the contour bit map so as to thicken or shadow the original image at a high speed. When the method of this invention is applied as to a large size region, since the work area for the reservation of the contour data becomes larger to exhibit less effectiveness of the space usage, the processing area is designed to be divided, if required, to be processed. In such a division method, it is required to set up as work areas a reservation area for keeping the contour bit map and a writing-in region for writing in the synthetic unit data in the use of the logical sum. Providing the latter mentioned writing-in region makes it possible to save a clipping treatment, and also give an advantage for effecting the thinning operation.

Abstract: One or more tapes being pulled toward the mandrel of a tube winding machine are tensioned by passing them over vacuum chambers (24, 50). Glue is applied to one or more tapes adjacent the vacuum chambers. If the tube winding machine stops for any reason, the vacuum chambers keep the tapes to which glue is applied taut, and those tapes are moved out of contact with the glue applying member. The length of each tape which is in contact with the glue applying member can be adjusted to adjust the amount of glue applied to the tape. Heat can be applied to each tape after glue has been applied in order to promote curing of the glue.

Abstract: A magnetic field heating device for heating metal including a means to create an alternating magnetic field passing this magnetic field through a dissimilar metal part to uniformly heat the part. This differs from induction heating of metal parts because the part is heated uniformly rather than being restricted to the skin or outside portions of the part. This unique heating is accomplished by utilizing a novel magnetic loop for creating a high density alternating magnetic field in the metal part to be heated.

Abstract: A load placed on the support 11 is balanced by a pulsed current in coil 13 whose duty factor is controlled by gating pulses applied to electronic switch 22. The control is effected according to the output of position sensor 14 through a digital processing unit 5 and the resulting measurement is displayed on unit 6. 
     Relatively cheap standard 16-bit digital circuits are used to generate the gating pulses by counting clock pulses. The discrimination available is limited to steps of one clock pulse between successive gating pulses and the clock frequency is limited by the 16-bit capacity of the digital circuits. To simulate greater discrimination and achieve greater accuracy of weighing successive groups of gating pulses are made to include an increasing proportion of pulses differing by one step in width from the other pulses. Thus by averaging over each group it is possible to interpolate between successive gating pulse widths separated from each other by one clock pulse.

Abstract: A security enclosure comprises two layers (12, 14) of electrically responsive fibrous material separated by a layer (16) of auto-combustible insulating material. The layers (12, 14, 16) extend over the whole area of the enclosure, and the length of the fibres of the fibrous material is greater than the thickness of the insulating material layer (16) so that piercing of the enclosure forces fibres from one of the fibrous material layers (12) to physically penetrate the insulating material layer (16) and contact the other fibrous material layer (14) to change an electrical characteristic of the fibrous material layers (12, 14). A detector (24) is provided to detect this change. In the event of attempted penetration through the layers (12, 14, 16) by means of laser or other non-physical penetration involving elevated temperature, the auto combustible insulating material layer (16) is ignited, the subsequent decomposition of the insulating layer (16) causing the electrically responsive layers (12, 14) to come into contact with one another to change a detectable electrical characteristic of the fibrous material layers (12, 14).

Abstract: Paging command messages received by a BTS, in a cellular radiotelephone system conforming to GSM regulations, are bundled at specific intervals into different types of paging request messages. These paging requests are bundled based on paging group and MS identifiers contained in the paging command message. These paging request messages are buffered for transmission to the MSs. 
     Paging request messages, in a specific embodiment of the invention, are asynchronously divided, for buffering, into two forms as governed by two types of MS identifications; namely, TMSI (temporary mobile station identity) and IMSI (international mobile station identity) types. The bundles are formed from different compositions of these two identification types in order to maximize the buffering capacity. 
     The probability of dropping paging messages is reduced by augmenting the serial synchronous page bundling process with a parallel, primarily asynchronous bundling arrangement. The paging messages are entered into two paging stacks for each paging group. Paging requests are constructed when one stack becomes full.

Abstract: A span processor receives volumetric data from an imaging apparatus and stores the data as a condensed display list in a span memory. After the volumetric data has been stored, the span processor converts the display list to a display list comprised of points and normal vectors which is stored in a point and normal display list memory. A model clipping circuit determines points which are to be displayed corresponding to desired model cut planes. A rotate circuit transforms the point and normal display list according to the desired orientation, and also converts the normal vectors into levels of shading according to the direction of the normal vector. The points in the transformed display list are clipped to a desired screen viewing region by a screen clipping circuit. A depth buffer, compare circuit, and an AND circuit determine voxels which do not lie behind other surfaces, and are proper to display. The AND circuit allows update of the depth buffer and an image memory buffer, the image memory buffer being a screen map. The image memory is displayed on a monitor. The models are manipulated and cut much more rapidly on a low end workstation than would be possible using conventional methods.

Abstract: In an information processing apparatus for implementing a neural network, if an input vector is inputted to a calculating unit (104), a neuron which responds to the input vector is retrieved in accordance with network interconnection information stored in a first storage (101) unit and the neuron number indicating the retrieved neuron is written in a first register (105). The calculating unit reads out the internal information of the neuron stored in a second storage unit (102) by using the neuron number, writes it in a second register (106), and calculates the sum of products of the outputs of the neurons and the connection loads of synapses connected to the neurons. By repeating the sequence of operations by the number of times corresponding to the total number of input vectors, a recognition process is executed. The neural network can easily be expanded by rewriting the contents of the first and second storage units.

Abstract: A method of depositing layers (54, 56) of intrinsic amorphous silicon and doped amorphous silicon sequentially on a substrate (50) in the same CVD chamber without incurring a dopant contamination problem. The method can be carried out by first depositing an additional layer of a dielectric insulating material prior to the deposition process of the intrinsic amorphous silicon layer (54). The additional layer of insulating material deposited on the substrate should have a thickness such that residual insulating material coated on the chamber walls is sufficient to cover the residual dopants on the chamber walls left by the deposition process of the previous substrate. This provides a clean environment for the next deposition process of an intrinsic amorphous silicon layer (54) on a substrate (50) in the same CVD chamber.
