Abstract: A large sized thin-walled shaped article having a complicated shape can be realized by improving fluidity at the time of shaping without deterioration of the intrinsic characteristic properties of an aromatic polycarbonate resin, namely, transparency, resistance to exfoliation of surface layer, thermal resistance, impact resistance, and chemical resistance. Specifically disclosed is a fluidity-improving agent containing 0.5 to 99.5 parts by mass of a polymer (A) which is obtained by polymerizing a monomer mixture (a) containing 0.5 to 99% by mass of (a1) an aromatic vinyl monomer, 0.5 to 99% by mass of (a2) a phenyl(meth)acrylate or a phenyl(meth)acrylate having a substituent in a phenyl group, and 0.5 to 5% by mass of (a3) a vinyl monomer having a functional group (X), and 0.5 to 99.

Abstract: In a trunk transmission network for transmitting information signals between nodes via paths, flexible path operation is achieved by setting up paths between source nodes and destination nodes after pre-classifying paths into a higher service class in which any loss of information occurring in that path is made good restored; and a lower service class which permits loss of information to occur in the path. The flexible operation is further achieved by arranging for each node, when it acts as a source node, to recognize the service class of the information signal it is sending to a destination node, and to select a path corresponding to that service class.

Abstract: The invention has the object of offering a channel-selection-type demultiplexing circuit which is capable of interchanging the time slots of demultiplexed signals when demultiplexing ultra-high-speed multi-channel multiplexed signal stream without expanding the scale of the circuits, and does not require the scale of the circuits to be expanded even if the speed of the transmission path increases. The invention is a channel-selection-type demultiplexing circuit capable of demultiplexing signals to a desired output port during bit demultiplexing, instead of simply demultiplexing the bits as in conventional devices, which performs bit demultiplexing based on a frequency division clock after selecting the bit signals to be demultiplexed to the desired output port from the N-channel multiplexed signal stream based on channel selection information.

Abstract: A pointer processor for use in an SDH/SONET transmission system, realizing a proper VC path management. A pointer interpreter constantly monitors 3X pairs of H1 and H2 bytes to contain a prescribed maximum size pointer AU-4-Xc that can possibly be received by the pointer processor, to obtain and hold an inside AU-size map indicating an occupation state of AU pointers on 3X pairs of H1 and H2 bytes, while generating and holding an assigned AU-size map indicating an assigned state of AU pointers on 3X pairs of H1 and H2 bytes according to an externally set AU pointer size, and compares these two AU-size maps.

Abstract: Both a test printing pattern during a forth direction printing and a test printing pattern during a back direction printing are displayed on a screen of a display apparatus. The test printing pattern is occurred at a predetermined detection position by counting a value of an up/down counter. A printing position drift between the forth direction printing and the back direction printing is shown on the screen. The optimum printing position drift having the smallest printing position drift amount is detected on the screen by the test printing patterns. A corrected result of the printing position drift is printed. A correction value of the printing position drift is renewed at an optimum value. The printing position drift in such as ruled lines is set at the minimum value. A high quality printing for a document data can be maintained and a high throughput for the document data can be obtained.

Abstract: An ink-jet recording head apparatus of charge modulation and continuous jet type comprising an annular ink pump chamber defined by the inner peripheral face of a cylindrical electrostrictive element, the annular side faces of a pair of elastic sealing members and the outer peripheral face of a fluid passage-providing insert, a tortuous inlet path connecting the ink pump chamber to a supply source of ink under pressure, and a tortuous outlet path connecting the ink pump chamber to an ink ejection orifice.

Abstract: An ink jet recording apparatus of a dot matrix type in which the amounts of charges given to ink droplets are controlled depending upon recording conditions. The apparatus comprises, in one embodiment, a central processing unit (CPU) capable of generating unit video data and dot data concerning an image to be recorded, a random access memory (RAM) for storing the unit video data, a selector for reading out predetermined number of unit video data among those stored in the RAM, an AND gate receiving the dot data and the selected unit video data and a digital/analog converter for generating from the output of the AND gate an image signal for giving charges to the ink droplets for controlled deflection of them.

Abstract: A coded label comprising a code pattern in which first and second segments respectively being substantially square and having reflection factors different from each other are arranged in at least four rows and two columns, and in which at least two of either of the first and second segments are arranged in each column and at least one is arranged in each of the uppermost and lowermost rows.

Abstract: This method for recognizing a specific pattern is characterized in a process of extracting feature parts wherein one or more certain feature parts of specific shape are extracted from an input pattern; the next feature part is then extracted from an extracting area which is determined from the position on the input pattern where a previous feature part was extracted; and in case that the next feature part fails to be extracted from the extracting area so determined, the initial condition is restored thereby extracting the feature part by successively limiting extracting areas.

Abstract: An automatic working machine adapted to carry out works such as cutting, filling, tightening and loosening, which comprises a visual unit for detecting, by means of the image information, a plurality of works and obstacles existing on an object, a working unit which works against a particular work and moves in relation to the object, and a tactile sensor provided in the vicinity of the working unit, the working unit being precisely positioned by the aid of the tactile sensor when the visual unit detects the particular work, the relative position being maintained during the operation, and the working unit along with the tactile sensor being retracted when the visual unit detects an obstacle, to avoid collision thereof with the obstacle.
