| 20080300124 | CENTRIFUGE - According to an aspect of the present invention, there is provided a centrifuge in which a steam sterilization of a sample flow passage is performed, the centrifuge including: a rotor configured to centrifuging a liquid sample; a drive portion that drives and rotates the rotor; a chamber that accommodates the rotor therein, the chamber having a first and a second penetration holes provided on an upper and a bottom portions thereof, respectively; and a first and a second valves disposed on the first and the second penetration holes, respectively; wherein a cooling gas is introduced through one of the first and the second penetration holes and discharged through the other to cool a periphery of the rotor before or after execution of a centrifuging operation of the liquid sample. | 12-04-2008 |
| 20090170683 | CENTRIFUGE - According to an aspect of the invention, a centrifuge includes: a rotor for separating samples; a motor for driving and rotating the rotor; a drive shaft for connecting together the motor and the rotor; a rotation sensor for detecting at least one of the rotation speed of the motor and the rotor; and a displacement sensor for detecting the swinging motion of the rotor or the drive shaft, wherein, after one of speed of the motor and the rotor is accelerated up to previously set rotation speed, when the swinging amount of the rotor or the drive shaft is equal to or more than preset allowable value, the supply of power to the motor is stopped to decelerate the motor, wherein, during the deceleration, signal from the displacement sensor is compared with the preset allowable value, and wherein when the signal from the displacement sensor becomes equal to or less than the preset allowable value, the motor is accelerated. | 07-02-2009 |
| 20090239729 | CENTRIFUGAL SEPARATOR - A centrifugal separator includes a sample line and a rotating apparatus portion including a rotor that has a rotor chamber. The centrifugal separator centrifugally separates a sample by supplying the sample from the sample line into the rotor and driving to rotate the rotor in the rotor chamber and discharges the centrifugally separated sample from the rotor via the sample line. The centrifugal separator includes a sterilizing apparatus for sterilizing at least a portion with which the sample is brought into contact by making a sterilizing fluid flow through the sample line. | 09-24-2009 |
| 20110028297 | METHOD FOR STERILIZING A CENTRIFUGAL SEPARATOR - A centrifugal separator includes a sample line and a rotating apparatus portion including a rotor that has a rotor chamber. The centrifugal separator centrifugally separates a sample by supplying the sample from the sample line into the rotor and driving to rotate the rotor in the rotor chamber and discharges the centrifugally separated sample from the rotor via the sample line. The centrifugal separator includes a sterilizing apparatus for sterilizing at least a portion with which the sample is brought into contact by making a sterilizing fluid flow through the sample line. | 02-03-2011 |

| 20080317486 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus for performing an image forming operation is disclosed that includes an image carrier on which a toner image is formed, an intermediate transfer member configured to transfer the toner image to a recording medium, the intermediate transfer member having a toner image forming area including an output image forming area and a non-output image forming area located outside of the output image forming area, the toner image forming area being wider than the output image forming area, and a detecting part configured to measure a physical quantity regarding an image quality of a first reference image formed in the output image forming area and a second reference image formed in the non-output image forming area. | 12-25-2008 |
| 20100040389 | IMAGE FORMING APPARATUS - A printer determines, in a process control, a reference exposure amount. A charging unit charges a surface of a photosensitive element to a target potential. After an exposure target area on the charged surface of the photosensitive element is exposed to a high adjustment exposure that corresponds to a high-exposure amount area, a control unit determines the reference exposure amount based on the target potential and a detected residual potential that is a result detected by a potential detecting unit as a potential of the target exposure area on the photosensitive element after being exposed to the high adjustment exposure. | 02-18-2010 |
| 20100129093 | DEVICE AND METHOD FOR DETECTING LIFE OF ORGANIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS - A device for determining an end of life of an organic photoreceptor includes a potential detecting unit that detects a residual potential of the organic photoreceptor, a temperature detecting unit that detects temperature of the organic photoreceptor in either one of a direct manner and an indirect manner, and a life determining unit that determines the end of life of the organic photoreceptor based on the residual potential detected by the potential detecting unit and the temperature detected by the temperature detecting unit. | 05-27-2010 |
