20100311171	VECTORS FOR GENERATING PLURIPOTENT STEM CELLS AND METHODS OF PRODUCING PLURIPOTENT STEM CELLS USING THE SAME - Stem cell reprogramming genes cloned into a single sustained expression-type Sendai viral vector are shown to reprogram differentiated somatic cells into induced pluripotent stem (iPS) cells without integration of vector sequences into the host cell's genome. The genes are transduced into normal differentiated somatic cells via infection with recombinant Sendai virus. After expression of the reprogramming genes and subsequent induction of pluripotency, the vector genome RNA including the reprogramming genes is removed from the cell to establish an iPS cell that is genetically identical to the parent somatic differentiated cell thus reducing the risk of tumorigenic transformation caused by random integration of vector sequences into the host genome. The method promises to provide safe, autologous iPS cells that can be used for human cell replacement and regeneration therapeutic applications.	12-09-2010

20100196993	PERSISTENTLY INFECTIVE SENDAI VIRUS VECTOR - A persistently infective virus vector is produced by using a gene so modified as to encode an amino acid sequence including a valine substituted for an amino acid residue at position-1618 in the amino acid sequence for an L protein of a persistently non-infective Sendai virus. A non-transmissible, persistently infective virus vector is also produced by defecting or deleting at least one of M gene, F gene, and HN gene. These virus vectors have no cytotoxicity, can achieve the sustained gene expression over a long period of time, is safe, and is therefore useful.	08-05-2010

20090064967	Control for an internal-combustion engine - A rotational speed parameter is detected in accordance with a rotational speed of the engine. A reference value of the rotational speed parameter is calculated. For each cylinder, an error between the reference value and the rotational speed parameter detected every predetermined crank angle is calculated as a relative speed parameter. For each cylinder, an integrated value is calculated by integrating the relative speed parameters over a predetermined period. For each cylinder, an average value per cylinder of the sum of the integrated values of all the cylinders is calculated. For each cylinder, an error between the integrated value of the cylinder and the average value is calculated. For each cylinder, the output of the engine is controlled in accordance with the error calculated for the cylinder such that variations in the output between the cylinders are suppressed.	03-12-2009

20090003868	IMAGE FORMING APPARATUS - The image forming apparatus includes a current detection circuit for detecting an input current from the commercial power supply to the apparatus, in which: when a current detected by the current detection circuit exceeds a predetermined value, a maximum current suppliable to a fixing portion is restricted; and when a temperature of the fixing portion falls below, in a situation where the maximum current suppliable to the fixing portion is restricted, the predetermined temperature lower than a control target temperature, a conveyance interval of a recording material conveyed to the fixing portion is extended. In the image forming apparatus, even when a consumption current of the image forming apparatus is increased during successive image formation, it is capable of controlling the consumption current so as not to exceed a maximum current of a commercial power supply, securing desired fixability, and minimizing decline of image forming performance.	01-01-2009
20090202266	IMAGE FORMING APPARATUS - The image forming apparatus, in the case where image forming is performed on a recording medium whose size covers a position of a second temperature detection element perpendicularly disposed to the recording medium conveyance direction, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a first power supply control is switched to a second power supply control. In the case where image forming is performed on a recording medium whose size does not cover a position of the second temperature detection element, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a conveyance control portion executes a control for extending the conveyance interval of the recording medium. Thus, an unduly large temperature rise in the non-sheet passing portion is prevented, and a good quality image can be provided without glossy unevenness in one sheet.	08-13-2009
