摘要:
A signal processing circuit having a data input-output (I/O) circuit, a microprocessor, a dedicated processing circuit, a local memory, and a memory access control circuit interconnected over a bus. The system bus connects to the data I/O circuit, microprocessor, dedicated processing circuit, and memory access control circuit. A local memory bus connects to the local memory. First, second, and third connection circuits connect between the system bus and local memory bus, between a first local bus in the dedicated processing circuit and the local memory bus, and between a second local bus in the data I/O circuit and the local memory bus. The memory access control circuit controls the first, second, and third connection circuits according to priorities assigned for the connection circuits and determines which of the second local bus, first local bus, and system bus will be connected to the local memory bus.

A PET-based polyester packaging film capable of weld-cut sealing and heat-shrinkage refers to a film obtained by biaxially orienting a material prepared through block copolymerization of a PET/PETG/polyester elastomer with an epoxy resin and a catalyst. This film eliminates the most serious weak points in physical properties of conventional PET films, and is useful for packaging of books, bottlesets, food containers, etc., for general packaging, packaging of industrial materials, and the like, and is further useful in the field of packing and packaging of daily commodities, civil engineering and construction members, electric and electronic members, and automobile vehicle members, etc. Moreover, this film can be produced through effective use of the huge amount of recycled PET bottles and inexpensive PET for fiber as a prepolymer, and thus is also highly beneficial socially. Still further, even if incinerated after use, this film produces a combustion heat value lower than that of a polyethylene or polypropylene. Thus, this film barely damages incinerators or the like, and emits no toxic gases.

In a moving picture data decoding apparatus, the storage of reference picture data in a picture memory is executed by dividing the picture memory into two memory areas. An address generator generates an address so that the reference picture data adjacent to the division may be doubly written into the two memory areas. As a result, the processing can be effected in a predetermined access time period irrespective of the read-out location.

It can be enabled an accurate diagnosis of osteoporosis by a simple method utilizing panoramic radiographs without requiring special skill or experience of a technician engaged in diagnosis of osteoporosis. It comprises an object region image acquisition means for enhancing the contrast of a mandible bone on digitized panoramic radiographs and extracting a portion of a mandible including a mental foramen and a mandibular base as an object region image; a discrimination and selection means for discriminating between a background portion and the portion of a mandible from the object region image and acquiring, as a judgment region image, a portion from which the background portion is removed; a defined image acquisition means for defining forms of a cortical bone and a cancellous bone constituting the mandible of the judgment region image; a means for specifying the cortical bone portion on the image in which the form is defined; calculation means for determining the thickness of the cortical bone based on the outline constituting the mental foramen and the cortical bone specified by the respective means; and an output means for outputting the determined thickness of the cortical bone.

There is provided a filtering circuit whose circuit scale is small and which is suitable for a digital data string in which data of luminance signals Y and color-difference signals Cb and Cr are regularly inserted or multiplexed. The digital filtering circuit includes a delay line composed of a plurality of D flip-flops which is operative with frequency of the data string in which the luminance signals Y and the color-difference signals Cb and Cr are regularly inserted or multiplexed a plurality of multipliers for multiplying a plurality of taps of the delay line by respective coefficients and an adder for adding outputs of said multipliers, wherein the taps connected to the multipliers is switched by selectors. It allows one digital filtering circuit to be used for processing the signals Y, Cb and Cr in a time division manner to realize the digital filtering circuit which uses less multipliers and adders and whose circuit scale is small.

A debug program is decoded in a command decoder to generate a debug start signal. Then, a signal processing operation is halted and a state of an internal circuit is latched and read to be supplied to an external circuit. When the reading of the state starts, a signal-processing continuation signal is generated, so that the signal processing operation is restored to be continued. Therefore, the debug program can be inserted to a program memory at plural addresses without braking the signal processing operation.

The present invention provides a method of manufacturing high-melting-tension heat-resistant transparent or opaque sheets, boards, and molds from polyethylene terephthalate (PET). The method is characterized in that a mixture of: (1) PET polyester whose melt flow rate (MFR) is 45-130 g/10 minutes (a); (2) coupling agent master batch (f) comprising coupling agent (d) and substrate (e), wherein coupling agent (d) is a mixture of compounds containing 2 epoxy groups (b) and compounds containing 3 or more epoxy groups (c); and (3) catalyst master batch (i) comprising coupling reaction catalyst (g) and substrate (h); is melted in a reaction-extruder to give PET polyester whose MFR is 40 g/10 minutes or less. The resulting PET polyester is molded into amorphous sheets or boards, and then heated again to a predetermined temperature to give transparent heat-resistant sheets or boards; or then vacuum-, pressure-, or vacuum-pressure-formed following heat-setting to give transparent heat-resistant or white opaque highly-heat-resistant mould articles.

An address generating circuit includes a latch circuit and two adder/subtractors. The inputs of the first adder/subtractor are from the latch circuit and from a distance relative to a value of a base pointer, and the output computes an address. The second adder/subtractor uses loop width information to adjust the computed address of the first adder/subtractor so that it falls within a loop area.

The present invention provides an osteoporosis diagnosis aiding apparatus that utilizes a panoramic radiograph. A digitalized image of the panoramic radiograph enters a personal computer (S210). The cortical bone at the lower edge of the mandibular molar in the panoramic radiograph is specified with a mouse to make that part a target of examination (S220). This extracted image is subjected to the following image processing. (1) Subject the image to median filtering so as to reduce noises throughout that image. (2) Find a skeleton constituted by micro-structural elements (S230). (3) Extract only components parallel to the tilt of the lower edge of the mandible (S240). (4) Binarize the image using Otsu's linear discrimination method, for example (S250). The binarized lines are then classified into three groups according to size, and can be determined as a risk of osteoporosis in a case where there is more than just a single line classified in the largest line group aside from the smallest line group.
