| 20090026261 | CONTROL GATE - A control gate includes a first exciting coil, a first detection coil, a second exciting coil, a second detection coil, a signal determination unit and an amplification factor setting unit. The first exciting coil forms a first alternating magnetic field in a passage. The first detection coil detects a variation in the first alternating magnetic field. The second exciting coil forms a second alternating magnetic field in the passage. The second detection coil that detects a variation in the second magnetic field. The signal determination unit includes a first amplifier which (i) amplifies a first detection signal of the first detection coil and (ii) determines a passage of the magnetic material based on the amplified first detection signal. The amplification factor setting unit sets a first amplification factor for the first amplifier based on a second detection signal of the second detection coil. | 01-29-2009 |
| 20090072821 | CONTROL GATE - A control gate includes an exciting coil and a detecting coil. The exciting coil forms an alternating magnetic field in a passageway at an entrance to or an exit from an area where taking out or bringing in of an object is controlled. The detecting coil detects a change of the magnetic field when magnetic substance contained in the object generating a large Barkhausen effect causes magnetic inversion in the alternating magnetic field. The exciting coil is provided above the passageway and has a winding wire wound along a horizontal plane. The detecting coil is provided in a side part of the passageway and has a winding wire wound along a vertical plane which is parallel to a passing direction of the passageway. | 03-19-2009 |
| 20090072969 | Baggage management gate - A baggage management gate including an exciting coil, a detecting coil and signal processing unit. The exciting coil forms an alternating magnetic field in a passage to an area from which manages objects to be carried in or carried out. The detecting coil detects a variation in the alternating magnetic field when magnetization of a magnetic material showing a large Barkhausen effect is reversed in the alternating magnetic field. The signal processing unit determines as to whether the magnetization reversal occurs in the alternating magnetic field due to the large Barkhausen effect or not, based on a signal detected by the detecting coil. The signal processing unit includes amplifier that amplifies the signal detected by the detecting coil with plural different amplification factors and output the amplified signals with each of the plural different amplification factors. | 03-19-2009 |
| 20090072979 | Baggage management gate - A baggage management gate includes a first reading device and a second reading device, a detecting device, a determining unit, a first opening and closing device and a second opening and closing device. The baggage management gate manages baggage that is restricted to be carried in or out from a predetermined region. And in order away from the region in which the baggage is managed, the first reading device, the second opening and closing device, the detecting device for both the first person and the second person, the first opening and closing device, and the second reading device are arranged in an entrance direction from the passage to the management region in which the baggage is managed. | 03-19-2009 |
| 20100116722 | FLAT DETECTOR AND MEDIUM DETECTOR - a flat detector includes a first flat member and a second flat member both made of a nonmagnetic nonmetal, a first conductive wiring that generates an alternating magnetic field, the first conductive wing being disposed on a surface of the first flat member facing toward the second flat member, a first layer made of a nonmagnetic metal and disposed at least on a surface of the first flat member, a second conductive wiring that detects a signal generated by magnetization reversal of a magnetic material, the magnetization reversal being caused by the alternating magnetic field generated by the first conductive wiring, the second conductive wiring being disposed on a surface of the second flat member facing toward the first flat member, and a second layer made of a nonmagnetic metal and disposed at least on a surface of the second flat member. | 05-13-2010 |
| 20100201355 | OBJECT DETECTING APPARATUS - An object detecting apparatus that detects an object including a magnetic body including: a detection signal acquiring unit that acquires a detection signal based on a magnetic signal; a disturbance source detection signal storage unit that stores a detection signal of a disturbance source that generates a disturbance component with respect to the detection signal; a determining unit that determines whether the detection signal acquired by the detection signal acquiring unit contains the disturbance component; an amplitude correction unit that corrects an amplitude of the disturbance source detection signal and generates an amplitude-corrected disturbance source detection signal; a disturbance component suppression unit that generates a determination signal by suppressing the disturbance component contained in the detection signal; and an object determination unit that determines whether the object is the object to be detected based on the determination signal. | 08-12-2010 |

| 20090023672 | AGE-2 APTAMER - An AGE-2 aptamer which binds to a glyceraldehyde-derived advanced glycation end product (AGE-2) but not to human serum albumin and comprises at least 35 bases and in which the cytosine content in the bases is at least 35%, or the guanine content in the bases is at least 32%. Since the AGE-2 aptamer can be used for detecting AGE-2, it can be used as a reagent for detection/diagnosis, and an agent for prevention/treatment of AGE-2 involved diseases such as: diabetic complications such as diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy; neurodegenerative diseases such as Alzheimer's disease; and proliferation, metastasis, and invasion of malignant tumors. | 01-22-2009 |
| 20100036103 | Method for producing apoprotein - A method and an apparatus for producing an apoprotein with which the apoprotein can be efficiently produced from a protein associated with cofactors such as metal ions. The method includes the step of adding an acid to a solution which contains a holoprotein, which is associated with a cofactor which is to be released under acidic conditions, and concentrating the solution with an ultrafiltration membrane. Accordingly, an apoprotein, which has released its cofactor, is produced, and the released cofactor is removed through the membrane along with the acid without reassociating with the apoprotein. | 02-11-2010 |
