摘要： A Fourier transform circuit in a receiver performs a Fourier transform on a orthogonal frequency division multiplexing signal received through a transmission channel for each symbol to sequentially reproduce a received reference vector sequence and a received vector sequence. An interleave circuit interleaves elements of the received reference vector sequence and the received vector sequence. A memory stores the received reference vector sequence. A vector modulation circuit modulates the received reference vector sequence by respective signal point vectors representing each signal point to generate a modulation vector sequence for each symbol. A metric generation circuit then obtains a difference between the received vector sequence and the modulation vector sequence to generate the difference as a branch metric sequence. A trellis decode circuit reproduces a data sequence on the basis of the branch metric sequence.

摘要： There is provided an apparatus of inspecting a packaged state by scanning a packaged printed circuit board with a fine light beam and detecting reflection beams of the fine light beam in a plurality of directions. A fine light beam emitted from a light source is scanned on the packaged printed circuit board substantially vertically thereto by means of a polygon mirror and a light projection f.theta. lens. An optical path correcting system receives reflection beams scattered from the packaged printed circuit board and corrects optical paths of the reflection beams. The correction is done in such a way that reflection beams having constant directional vectors regardless of the change of the scanning position of the fine light beam are received and guided to light receiving positions complying with a height at a scanning position on a plurality of photoelectric conversion devices. Through this, the packaged state of parts is inspected at a high speed, with high accuracy and over a wide range without expanding the light receiving area of the photoelectric conversion device and without causing characteristics of triogonometrical survey to change with the scanning position.

摘要： Encoding and decoding devices which are capable of increasing the encoding and decoding speed. In arithmetic encoding, there is a possibility of encoding with high efficiency which is very close to the entropy of the information source, but the encoding and decoding time is generally longer than that in another encoding systems such as an MMR encoding system. For example, in a standard facsimile equipment, about 1.3 sec is required for encoding the picture information in an A4-size copy. In prediction encoding, a memory for storing the past reference symbols and the predicted values therefor is necessary for prediction. Since the memory capacity is generally large, a large-capacity RAM is used. The encoding time is therefore greatly dependent on the access speed of the RAM. In the present invention, a high-speed register for storing the predicted value for a special symbol pattern is provided separately from the RAM so that the predicted value of the special symbol pattern is read from this register, thereby enabling high-speed encoding.

摘要： A method for the preparation of an illuminance-correcting light transmitting filter employed in an exposure device adapted for the preparation of the phosphor screen of the color cathode ray tube. The laser light modulated with a light modulator is radiated to the surface of the filter base plate on which a thin layer of the recording material is previously formed. A pattern of through-holes of variable size or density is formed as the thin layer is vaporized so that the light transmitting filter may be prepared with high accuracy and in a shorter time. The laser light is modified with the light modulator, and the filter base plate is securely mounted to a movable stage, the movement of which in the X- and Y- directions is controlled under the commands of a computer unit.
