Abstract: A measurement apparatus includes a generation section and a measurement section and performs a predetermined measurement using a flow channel device including a narrow channel through which particles pass by a flow of a fluid and a measurement electrode section provided in the vicinity of the narrow channel. The generation section generates, in the measurement electrode section, an AC voltage that is higher than a characteristic frequency defined by a conductance of the fluid including the particles in the narrow channel and an electrical double layer capacitance formed by the measurement electrode section and has a frequency range indicating a conductance corresponding to a size of the particles. The measurement section measures, while the AC voltage is applied to the measurement electrode section, an electrical amount including at least the conductance obtained when the particles pass through the narrow channel.

Abstract: PURPOSE:To prevent breaking of an ozone layer by using alcowax to fix a ferrite core substrate and using an alcohol-base detergent such as isopropyl alcohol, hydrocarbon base detergent, or ketone-base detergent as a detergent. CONSTITUTION:A ferrite core substrate for the production of a magnetic head is fixed with using alcowax, processed and then cleaned to remove the alcowax by using at least one kind of detergent selected from alcohol detergents, hydrocarbon detergents, and ketone detergents. Thus, a problem of breaking the ozone layer can be solved. The alcowax essentially consists of a terpenephenol resin, higher alcohols, and synthetic amides. These alcohol-base detergents are inexpensive and do not break the ozone layer.

Abstract: PROBLEM TO BE SOLVED: To prevent effectively nonspecific adsorption of an intercalator onto the solid state surface.
SOLUTION: The solid state surface f for detecting hybridization between a nucleic acid D for detection and a target nucleic acid T is covered with a material to be positively charged such as avidin or modified with a functional group to be positively charged resulting from a silane coupling agent, to thereby prevent nonspecific adsorption of the fluorescent intercalator I onto the solid state surface f. Thus this method is especially useful when detecting hybridization on the solid state surface f by using the fluorescent intercalator I.

Abstract: PROBLEM TO BE SOLVED: To obtain a three-dimensional image reduced in strain and high in resolving power within a wide range region in a short time and to sharply reduce the exposure quantity of X-rays as compared with conventional equipment. SOLUTION: A rotary drive device 31 integrally rotates a radiation source 10 and a two-dimensional sensor 20 around a subject 50. An X-ray tube bulb 13 irradiates the subject 50 in a pulsating manner and an X-ray/light conversion element 21 converts an X-ray transmission image to an optical image. A CCD camera 23 picks up the optical image and a data processor 40 reconstitutes the three-dimensional image on the basis of the obtained two-dimensional images in a plurality of directions while a display monitor 46 displays the three- dimensional image. A controller 39 controls the distance between the X-ray tube bulb 13 and the X-ray/light conversion element 21 and the focal size of the X-ray tube bulb 13 on the basis of the size of the subject 50.
