Abstract: A floating type magnetic head device of the present invention includes a slider capable of floating above a recording medium while moving relatively to the recording medium, and a magnetic head. The magnetic head is incorporated inside a cavity section formed substantially in the center of the slider. By incorporating the magnetic head inside the cavity section, the magnetic head can be protected, thereby reducing a possibility of head crash of the magnetic head due to its contact with dust or a projecting object existing on the surface of the recording medium. Further, by disposing the magnetic head substantially in the center of the slider, it can be avoided that the direction of an air stream at the center of the slider varies depending on an instantaneous position in a radial direction of the recording medium, thereby providing stable floating characteristics of the floating type magnetic head device and improving accuracy of recording.

Abstract: An automatic focusing apparatus of a video camera automatically matches a focus in response to a video signal obtained from an image sensing circuit. The automatic focusing apparatus detects the level of a high frequency component of the video signal, to supply a focus evaluating value which takes a maximum value in an in-focus position. A focusing motor controlling circuit performs an automatic focusing operation by a hill-climbing servo system based on the supplied focus evaluating value. A determination is made by employing a fuzzy inference with respect to the initialization of the direction of movement of a lens when the automatic focusing operation starts, the selection of a focusing area from a plurality of areas, and the reactivation of the automatic focusing operation due to a change of an object after the automatic focusing operation is once completed.

Abstract: The system utilizes a solid-state memory (20) for continuously storing the information and reading it out on a time-delayed basis. An information signal is converted by a converter (14) into a digital format and compressed using conventional compression algorithms in an analyzer and converter (14). The compressed digital signal is then sequentially written into successive locations in a random access memory (20). These locations are sequentially addressed at a later point in time to read the digitized information out of the memory on a time-delayed basis relative to when it was stored in the memory. The time delay is related to the anticipated reaction time it takes to cycle completely through all of the address locations in that portion of the memory being used to store the information. The digitized information that is read out of the memory can be synthesized by a synthesizer (24) or otherwise suitably processed to reconstruct the original information signal as a delayed signal.

Abstract: Disclosed herein is a printer system comprising print data setting means, data converting means and printing means. The print data setting means outputs one-bit print data for binary expression. These print data ate converted by the data converting means to the same number of bits as in the print data for multivalued expression. The binary expression print data from the data converting means and the multiple-bit, multivalued expression print data from the print data setting means are input to the printing means for printing. This allows the printer system to implement multivalued expression printing such as a half tone and smoothing printing as well as high-speed binary expression printing. The printer system further comprises print pattern storing means which stores picture elements with respect to each of a plurality of kinds of multivalued expression. These plurality of kinds of multivalued expression are set with a plurality of picture elements for multivalued expression in units of picture elements. When the print data setting means outputs a given kind of multivalued expression, the picture elements corresponding thereto are selectively retrieved from the print pattern storing means for input to the printing means. This permits printing in a plurality of kinds of multivalued expression with no drop in the printing speed.

Abstract: Method and apparatus for rendering data for display. The data represents a model space and the method includes the following steps. A first step associates individual points in the model space with individual vertices (V) of an irregular grid cell enclosed by faces. Each of the points has an associated luminosity value and an associated opacity value. A next step orders the faces of the grid cells. The faces are preferably ordered by depth referenced to a view plane. A further step processes individual faces for determining, for all viewing rays that project from pixels on the view plane and that intersect the face being processed, an amount of light arriving at the pixel. The amount of light arriving at the pixel is a function of both the luminosity and the opacity of a grid cell that lies adjacent to the face and through which the viewing ray passes.

Abstract: The invention relates to a method for the automatic classification of digitally modulated signals, in which a complex information signal derived from the digitally modulated signal and modulated in accordance with a type of a modulation which is initially still unknown is transformed into several intermediate signals, the information signal and the intermediate signals being processed further independently of one another; the complex envelope of the information signal only assumes a limited number of states in the state diagram of the complex plane. To achieve the highest possible reliability in the detection of the type of modulation, it is proposed in accordance with the invention that the transformations are selected which, in the state diagram, transform the states which are symmetric with respect to the origin of the complex plane into a lower number of states which are asymmetric to the origin, that from the information signal and, respectively, the intermediate signals, the in each case associated power density spectra are generated which are examined for the existence of lines, and the number, frequency and amplitude of which are determined and forwarded to a classifier which determines from these the type of modulation. <IMAGE>
