  • Patent number: 6991762
    Abstract: A suction generating device for a sample analysis device is provided. The device comprises four parts, namely, a cover plate 61, a middle plate 62, a bottom plate 63 and an operation plate 64. A protruding portion 642 for compressing the suction generating chamber is formed in an approximately center portion on the lower side of the operation plate 64, a protruding portion 641 for operation is formed in an approximately center portion on the upper side of the operation plate 64. A cavity 631 for inserting the sample analysis device therein is formed in an approximately center portion in the bottom plate 63; and a hole 632 for light irradiation is punched in a determined portion in the cavity 631. A concave portion 623 for fitting the operation plate 64 therein is formed in the middle plate 62, and a window section 621 is formed in the center of the concave portion 623 to let the lower protruding portion 642 on the operation plate 64 protrude therethrough.

  • Publication number: 20060018790
    Abstract: This invention provides a device for analyzing a sample which is capable of performing rapid and precise analysis of a small amount of sample, and whose gradient in a measuring apparatus is not limited. This device comprises approximately a rectangular plate shaped body comprising a base member made of resin and a transparent covering. A first depressed cylindrical concave portion is formed in the upper surface of the base member, and a groove is formed in communication with the first depressed cylindrical concave portion, the groove extending to the end of the protrusion portion 5c, and a second depressed cylindrical concave portion which is smaller than the first depressed cylindrical concave portion is formed in a certain position in the groove, the end of the groove opening to the outside at the end of the protrusion portion 5c. Then, the transparent covering is placed over the upper surface of the base member and then integrated together.

  • Patent number: 5123013
    Abstract: A cell synchronizing apparatus and method for synchronizing the transmission and reception of a data train between switching systems. The data train is sectioned into a plurality of packeted data cells and synchronization cells of equal fixed length. A synchronization pattern is included in each synchronization cell. A time position of the synchronization pattern is detected and sequentially stored in a memory. Synchronization is determined from the relative positional relationship among time positions of equal value stored in the memory.
