20090214234 | FIXING DEVICE, IMAGE FORMING APPARATUS, AND METHOD OF DETECTING AN ABNORMALITY OF A FIXING DEVICE - A fixing device according to this invention includes a heating roller, a heater driver, a thermistor, and a CPU. The heating roller has a heater and heats a recording sheet. The heater driver drives the heater. The thermistor detects a surface temperature of the heating roller. The CPU stops an operation of the heater driver when the surface temperature of the heating roller becomes higher than a predetermined temperature and, thereafter, causes the thermistor to perform detection of the surface temperature of the heating roller for a predetermined time period and issues an alarm about occurrence of a first abnormality when the surface temperature of the heating roller fails to drop in the predetermined time period. | 08-27-2009 |

20080253213 | SEMICONDUCTOR MEMORY DEVICE AND REFRESH METHOD FOR THE SAME - A refresh method for a semiconductor memory device features high noise resistance, lower power consumption, and lower cost. All word lines of one or more memory cell blocks that have not been selected in a self refresh mode are controlled to have a floating potential substantially at ground level. Even when a word line and a bit line are short-circuited, this control prevents destruction of memory cell information, which may be caused by noise, and also prevents generation of leakage current. A fuse, etc., for preventing generation of leakage current is unnecessary, so that lower cost is realized. | 10-16-2008 |

20120209242 | METHOD FOR ALLEVIATING CONDITION OF SPINAL CANAL STENOSIS BY LOCAL ADMINISTRATION OF MEDICINE - Disclosed herein is a method for alleviating the condition of spinal canal stenosis, including: transluminally placing a catheter in a lumbar artery, iliolumbar artery or lateral sacral artery at the proximity of a narrowed area of a spinal canal; and injecting a vasodilator into the artery via the catheter. | 08-16-2012 |
20120209329 | METHOD FOR DILATING BETWEEN SPINOUS PROCESSES - Disclosed is a method for dilating between spinous processes wherein a filamentous body provided with an expansion body is percutaneously inserted to locate the expansion body between the spinous processes, a filling material is injected into the expansion body to dilate between the spinous processes, and the expansion body is cut off from the filamentous body to be located between the spinous processes. This method exerts very little burden on the patient. | 08-16-2012 |
20120232557 | METHOD FOR IMPROVING BLOOD FLOW IN BONE HEAD - A method for improving the blood flow in the bone head, the method including the steps of extending a long tubular body, which has a cutting tool at its foreend, close to the entrance of the retinaculum artery and performing drilling on the bone head by using the cutting tool. This method makes it possible to improve the blood flow in the bone head with a minimum of burden on the patient. | 09-13-2012 |
