  • Publication number: 20140212132
    Abstract: A method of tap coefficient correction includes: obtaining a synchronization symbol difference between a first polarization and a second polarization orthogonal to the first polarization; obtaining a delay amount of each of the first polarization and the second polarization in an adaptive equalizer; calculating, in a case where a horizontal axis represents a tap number and a vertical axis represents a tap coefficient and a tap number or a nearest tap number with which an area of a drawn figure is halved is set as a gravity center of tap coefficients, a correction reference gravity center of the tap coefficients set in the adaptive equalizer, based on the synchronization symbol difference and the delay amount; and performing a correction of shifting an entire tap coefficients in units of symbol to cause the correction reference gravity center to be closest to a tap center.

  • Publication number: 20140162351
    Abstract: An operating efficiency of an observer is considerably restricted since it is not known at which position a culturing cell is disposed among a great number of pieces of holes of a culturing sheet. The culturing sheet is configured by a partitioning wall, a hole isolated by the partitioning wall, a local culturing region formed with plural local culturing region pillars a height of which is lower than that of the partitioning wall at a portion of a bottom face, and identification mark pillars formed at an identification mark region which differs from the culturing region at the bottom face of the hole. An identification mark is prevented from being unable to be optically recognized by adhering a spheroid to the identification mark region by making a diameter and a height of the identification mark pillar smaller than a diameter and a height of the local culturing pillar.

  • Publication number: 20130323839
    Abstract: Provided is a culture sheet which enables a technique for forming a three-dimensional tissue having uniform diameter without applying any chemical on the surface of a culture substrate. On the culture sheet (150) of the culture substrate, a plurality of holes (152) are formed and nanopillars (153), which are capable of controlling the adhesiveness and migration ability of cells, are formed on the bottom surface of each hole (152), said bottom face serving as a culture surface. The culture surface of each hole (151) is provided with a partition wall (152) and the internal nanopillars (153) are formed in the vicinity of the center of the hole (151). Owing to this configuration, the interaction among the disseminated cells can be restricted so that uniformly sized three-dimensional structures of the cells can be formed.

  • Patent number: 7986376
    Abstract: It is possible to realize a driver circuit which exhibits low power consumption and high image quality in a liquid crystal display device used in miniaturized portable equipment. In a liquid crystal display device which includes a liquid crystal display element and a liquid crystal driver circuit, the liquid crystal driver circuit is mounted on one side of a liquid crystal display panel. The liquid crystal driver circuit can output counter electrode voltages of two systems and hence, the liquid crystal driver circuit can select a first mode in which the first counter voltage and the second counter voltage have the opposite polarities from each other and a second mode in which the first counter voltage and the second counter voltage have the same polarity. Due to such constitution, while driving the liquid crystal display device in the first mode, the second mode is selected depending on a video signal thus realizing power saving.
