20100227820 | Effect of Porcine Sheath Proteins on the Regeneration Activity of Periodontal Ligament - The purpose of this study was to identify the periodontal regeneration factors in enamel protein shown to induce cementum- and osteo-promotive activities in vivo. The cementum regeneration (CR), a part of periodontal regeneration, was examined by using experimental cavities prepared in a buccal dehiscence dog model. The CR activity was found in the aggregate consisted of sheath proteins along with a small amount of amelogenins separated from newly formed secretory enamel. The sheath proteins were purified to be homogeneous, and examined for the alkaline phosphatase (ALP) inducing activity of human periodontal ligament (HPDL) cells. Application of 17 kDa sheath protein induced ALP activity in HPDL cells. Peptides synthesized from the sheath protein sequence also showed ALP inducing activity. The 17 kDa sheath protein has cell differentiation activity. | 09-09-2010 |

20130229137 | POSITION CONTROL DEVICE FOR ELECTRIC MOTOR - Position control device for electric motor inputs deviation signal between angle command and angle detection value to position control section and calculates angular velocity command, inputs deviation signal between this angular velocity command and angular velocity detection value to speed control section and calculates torque current command, and controls, according to this torque current command, the electric motor current control section. The Position control device has disturbance observer section which inputs the torque current command and the angular velocity detection value and estimates signal corresponding to disturbance torque; rate-of-change limitation section which has limiter inputting disturbance observer output value by this disturbance observer section and performing rate-of-change limitation of upper and lower limit values of the angle command; and target value filter section which is configured by control gain equivalent to the speed control section and through which the angular velocity command from the position control section passes. | 09-05-2013 |
