  • Patent number: 7579760
    Abstract: A vibrator includes a vibrating body having a substantially quadrangular prism shape and including four side surfaces extending in the longitudinal direction of the vibrating body. A common electrode is formed on substantially an entire surface of one of the side surfaces of the vibrating body. Split electrodes extend in the longitudinal direction on another side surface opposite to the side surface on which the common electrode is formed, and are spaced from each other in the width direction of the side surface on which the split electrodes are formed. In the vibrating body, a first polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the split electrodes. A second polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the common electrode.

  • Publication number: 20070105143
    Abstract: Human- and mouse-derived bHLH type transcription factors were isolated. These transcription factors shared homology with the transcription factor DEC1, the expression of which is induced in human cartilage cells when differentiated with cAMP. Thus, these isolated transcription factors are thought to be novel transcription factors belonging to the DEC1 subfamily. The transcription factors of the present invention are also homologous to mouse Stra13 and rat SHARP that are related to neurocyte differentiation. The transcription factors of the present invention may be used as tools for developing pharmaceutical agents for diseases related to the differentiation and proliferation of cells.
