  • Publication number: 20070202611
    Abstract: The present invention is to provide a simple membrane assay method for detecting or quantitating an analyte in a specimen sample using an assay device equipped with a membrane bound with a capture-substance to capture the analyte, comprising the steps of filtering a specimen sample using a filter, dropping the filtrate onto said membrane and detecting the presence of the analyte in said specimen sample, as well as a simple membrane assay kit for detecting the presence of an analyte in a specimen sample, comprising (1) a filter tube, and (2) an assay device equipped with a membrane bound with a capture-substance to capture the analyte. The method or the kit can decrease the occurrence of false positivity and can provide a highly accurate detection of the analyte such as pathogen and antibody in a specimen collected in a medical scene or by an individual.

  • Patent number: 7177960
    Abstract: To display a horizontally oblong movie on a vertically oblong display portion, the movie may be displayed with being rotated 90 degrees by a CPU while the display portion is held in an orientation where the display portion is wider than tall. Since this arrangement puts a heavy load on the CPU, the mobile terminal according to the invention is adapted to implement the movie rotation by processings in the display portion. More specifically, an image memory in the display portion has a foursquare figure each side of which has a length the same as a longer side of a display panel of the display portion. A picture data is written on the memory in the same direction as a direction in which the picture data is read out to be transferred to the panel by the driver portion, and the driver portion rotates the picture data when transferring it.

  • Patent number: 6934959
    Abstract: A disk recording and/or reproducing apparatus includes a mechanical deck having a disk receiver with a disk carrying unit for carrying a disk, a disk recording and/or reproducing section for recording and/or reproducing the disk received in the disk receiver, and an outer case housing the mechanical deck. A relaxation mechanism and a lock mechanism are disposed between the mechanical deck and the outer case. The relaxation mechanism prevents vibration from being transmitted mutually between the mechanical deck and the outer case. The lock mechanism locks the mechanical deck to the outer case in such a manner as to oppose a relaxing operation of the relaxation mechanism. Thereby, operational vibration, noise and the like caused to the mechanical deck during recordation and/or reproduction can be prevented from being transmitted to the outer case's side.
