20100213163 | SHAPING METHOD OF THIN FILM AND MANUFACTURING METHOD OF PERPENDICULAR RECORDING MAGNETIC HEAD USING THE SAME - The present invention relates to a shaping method of a thin film layer and a manufacturing method of a perpendicular recording magnetic head using the same. In the thin film layer shaping method according to the present invention, since a second thin film of a lower etching rate is etched by a preliminary etching amount allowing for a difference between the etching rate of the second thin film and an etching rate of a first thin film in side-by-side relationship with each other, both the first and second thin films can be etched by the same etching amount through a subsequent etching step, so that the thin film layer can be shaped into a given shape. Thus, the surface of the thin film layer can be planarized. | 08-26-2010 |

20140246335 | METHOD OF DETERMINING HEMATOCRIT VALUE, QUANTATIVE ANALYSIS METHOD, AND SENSOR CHIP - A technique and a sensor chip allowing determination of a hematocrit value of a blood sample in a short period of time with low cost are provided. A response current obtained by sweep of a voltage applied across a working electrode for determination and a counter electrode for determination included in a sensor chip is measured and a hematocrit value is derived based on followability of the response current to temporal change in swept applied voltage. Therefore, it is not necessary to stand by until oxidation reduction reaction of an oxidation reducing substance is stabilized for determining a hematocrit value as in a conventional method of determining a hematocrit value, and thus a hematocrit value of a blood sample can be determined in a short period of time. Since no oxidation reducing substance is necessary for determining a hematocrit value, a hematocrit value can be determined with low cost. | 09-04-2014 |
20140246336 | SUBSTANCE DETERMINATION METHOD - A technique allowing improved determination accuracy in quantifying a substance to be determined by lessening influence by a current component different from an oxidation current is provided. The oxidation current results from oxidation of a reducing substance generated through reaction between an enzyme and the substance to be determined. Current components are contained in a response current resulting from application of a determination potential, referenced to a counter electrode, to a working electrode. Since a conditioning potential higher than a determination potential is applied as a pulse to the working electrode, influence by a current component different from an oxidation current can be lessened. Thus, the response current can be measured in a stable manner and determination accuracy in quantification of a substance to be determined which is contained in a specimen can be improved. | 09-04-2014 |
20140373347 | METHOD FOR MANUFACTURING BIOSENSOR - Provided is a technique capable of easily manufacturing a biosensor in which each of an enzyme layer and a mediator layer contains a hydrophilic polymer having no double bond of oxygen atoms and thereby which can be stored for a long period. Since an enzyme layer and a mediator layer are formed together as a reaction layer, there is no need to individually form enzyme layer and mediator layer on a cover layer and an electrode layer, respectively, as in a conventional biosensor, and reaction layer can be easily formed. Since each of enzyme layer and mediator layer contains the hydrophilic polymer having no double bond of oxygen atoms, a reaction between an enzyme and a mediator can be suppressed, and reduction of the mediator in mediator layer can be suppressed, in a stored state. Therefore, a biosensor which can be stored for a long period can be easily manufactured. | 12-25-2014 |
