| 20120219595 | BIODEGRADABLE FIBER AND FIBER WADDING FOR FILLING BONE DEFECTS AND METHOD FOR PRODUCING THE SAME - A fiber wadding formed from a biodegradable polymer fiber containing calcium carbonate fine particles including silicon that is characterized in that hydroxyapatite is precipitated and scattered nearly uniformly on the surface of the biodegradable polymer fiber is disclosed. Further, a method for production of fiber wadding that includes the steps of heating and kneading silicon-containing calcium carbonate fine particles and a biodegradable polymer to produce a composite, dissolving the composite by mixing the composite with a solvent to obtain a spinning solution, processing the spinning solution into fiber wadding by using electrospinning method, and alternatingly immersing the fiber wadding in a calcium aqueous solution and a phosphate aqueous solution to cause precipitation of hydroxyapatite in an approximately uniformly scattered manner on the surface of the fibers is disclosed. | 08-30-2012 |

| 20110108117 | PHOTOSENSITIZER AND PHOTOVOLTAIC DEVICE - Disclosed is a novel photosensitizer that can absorb light in a wide visible light region and in the case of a very thin film form, can enhance a light absorption efficiency by virtue of a large light absorption coefficient. The photosensitizer is used for metal oxide semiconductor electrodes and comprises a metal complex represented by a general formula ML | 05-12-2011 |
| 20100262291 | POWER ASSIST DEVICE AND ITS CONTROL METHOD - It is possible to provide a power assist device which can maintain a stable contact state without causing an oscillation phenomenon even if a robot is brought into contact with an environment. A method for controlling the power assist device is also provided. The power assist device includes: an inner force sensor which detects an operation force applied by an operator; an operation handle having the inner force sensor; a robot arm which supports the operation handle; an actuator which drives the robot arm; the actuator and a control device which measure or estimate a force applied when the robot arm is brought into contact with an environment; and the actuator and the control device which detect or estimate a motion speed of the operation handle. The control device acquires a corrected external force according to the operation force detected by the inner force sensor and an external force detected by the actuator and the control device as external force derivation means and controls the actuator so that the corrected external force acts on the operation handle. | 10-14-2010 |
