    • A method for the attachment of solder powder includes the steps of treating an exposed metallic surface of an electronic circuit board with a tackifier compound, thereby imparting tackiness to the metallic surface to form a tacky part, and supplying the tacky part with a solder powder slurry suspended in a liquid, thereby inducing attachment of the solder powder. A method for the production of a soldered electronic circuit board, includes the steps of treating an exposed metallic surface of an electronic circuit board with a tackifier compound, thereby imparting tackiness to the metallic surface to form a tacky part; supplying the tacky part with a solder powder slurry suspended in a liquid, thereby inducing attachment of the solder powder, and thermally fusing the attached solder powder, thereby forming a circuit.

    • An image information recording/reading method and apparatus for positive and short-circuited reading system capable of obtaining both moving and still pictures with improved image quality. The method and apparatus are designed to obtain favorable images in the imaging of both still and moving pictures by applying a necessary and sufficient voltage to avoid the influence of fixed noise at the time of still picture imaging, and applying a higher voltage than that of the still picture imaging at the time of moving picture imaging, in which the intensity of the radiation (recording light) is limited because of the continuous irradiation of the radiation (recording light).

    • A receiver of a CDMA system using a spread spectrum scheme is provided, which, particularly in a case where the RAKE synthesis is performed, stably extracts path timings to be synthesized and realize a reliable RAKE synthesis. Self correlation of a replica of a spreading code is calculated on the side of the receiver and an upper and lower threshold values obtained by incorporating the self correlation value thus calculated in an error range corresponding to a receiving signal quality are used as judge references for judging an output of a searcher circuit. When the output of the searcher circuit is within a range defined by the upper and lower threshold values, it is deemed as an invalid correlation value due to self correlation and, when the output of the searcher circuit is out of the range, it is deemed as effective path timing to be synthesized.
