A plurality of the sheet-like plates including an outermost layer of this laminated body comprises a flat portion substantially perpendicular to the magnet, and an extended portion bent to a direction substantially parallel to the magnet. A part of the sheet-like plate having the extended portion disposed to the outermost side is formed into a thickness smaller than thicknesses of the other parts.

Abstract: A reactor comprises a main body having a flow path substrate and a crystal substrate chemically bonded to the flow path substrate to form a flow path for running a sample to be measured and a reactor tank connected to the flow path. An adsorption film is disposed in the reactor tank for adsorbing a specific substance contained in the sample to be measured. A measuring device measures a physical quantity of the specific substance contained in the sample and adsorbed by the adsorption film.

Abstract: In order to provide a reactor, a micro reactor chip, and a micro reactor system which can maintain high sensitivity without residual stresses on a crystal oscillator and unwanted oscillation modes, both surfaces of an AT-cut crystal plate 100 is deposited or sputtered with gold to prepare a detection electrode 601, an opposite electrode 602, and wiring to both electrodes. A resist is then formed on a cleaned silicon wafer. Polydimethylsiloxane (PDMS) is then poured onto the silicon wafer and allowed to cure. The PDMS is then peeled from the silicon wafer to form a groove 500 in the PDMS. The PDMS is then laid on the crystal plate. When the crystal substrate side is then irradiate with ultraviolet light the silicon-carbon bond between the crystal and the PDMS is cut, thus causing the crystal and the PDMS to bond to each other by means of a siloxane bond. The liquid introduction port and the liquid discharge port are then cut to form the reactor.

Abstract: In order to make it possible to predict a dissociation constant at an initial stage of reaction, a concentration sensor for a sample is provided on a downstream side of a mass sensor. This makes it possible to learn concentration of a sample solution at the time when a mass is detected by the mass sensor. When the concentration and the mass are substituted in a predetermined logical expression, it is possible to obtain a predicted value of a dissociation constant. The concentration sensor is a capacitor constituted by electrodes opposed to each other. Since a dielectric constant changes when analytes are present between the electrodes, it is possible to detect analyte concentration according to the dielectric constant. Since it is possible to reduce a size of the capacitor, it is possible to keep a size of a micro-reactor small. Note that the mass sensor outputs a resonance frequency of a quartz resonator. A measuring apparatus can calculate a mass from transition of this frequency.

Abstract: In a circuit-integrated motor, it is an object of the invention to solve a problem that high power output is hampered by a heated electronic component, and to provide a compact high-power motor with a self-cooling fan which is capable of affording a significant cooling effect on the electronic component and winding wire. A self cooling fan (15) disposed close to and in an opposed relation to a top face of a rotor frame (11) has a peripheral-face opening (16), and an electronic component or a radiator attached with the electronic component is located in the course of a flow passage (17) of cooling air guidedly discharged from the peripheral-face opening (16).
