摘要： A light receiving element provides a current signal corresponding to an amount of received light scattered by suspended particles moving at a predetermined speed to a pulse width measurement circuit and a current-voltage conversion circuit via a filter circuit. A pulse width measured from the current signal is converted into a voltage value based on a predetermined relationship by a pulse width-voltage conversion circuit, and is provided to a voltage comparison circuit. The current-voltage conversion circuit converts a peak value of the current signal into a voltage value, and an amplifier circuit amplifies the signal at a predetermined amplification factor and provides the same to the voltage comparison circuit. The voltage comparison circuit uses the voltage value converted from the pulse width as a boundary value, and the suspended particles causing the scattered light are detected as microorganisms when the peak voltage value is smaller than the boundary value.

摘要： In a detection apparatus, an inlet and an outlet are opened and an air introducing mechanism is driven to introduce air to a case, and airborne particles are electrically attracted and held on a collecting jig 12. After introduction, the inlet and outlet are closed, and amount of fluorescence received by a light receiving element resulting from irradiation with light emitted from a light emitting element is measured by a measuring unit. Thereafter, the collecting jig is heated by a heater and the amount of fluorescence after heating is measured by the measuring unit. Based on the amount of change in the amount of fluorescence before and after heating, the amount of microorganisms collected by the collecting jig is calculated at the measuring unit.

摘要： This invention provides a process for accumulating different organic molecular films on oxidized III-V-group compound semiconductor substrates in order to produce a stable, high-quality organic monomolecular film that is three-dimensionally regularly arranged, as well as a process for producing a fine pattern of such organic films. This organic film is formed by immersing a III-V group compound semiconductor substrates in a vessel containing a solution containing phosphonic acid dissolved into a solvent in order to form a self-assembled film, and placing the substrate into a different solution to adsorb metal ions to the surface of the film, or immersing the substrate in a bromide or an acid or alkali solution to denature functional groups, then immersing it in a solution containing organic molecules that are selectively chemically adsorbed to the modified functional groups. These steps are repeated to form a stable, high-quality multilayer film that is three-dimensionally regularly arranged, while controlling film thickness with an accuracy on the scale of thickness of a molecular layer. In addition, the present invention realizes the formation of a fine composite three-dimensional organic self-assembled film of the order of nanometer, characterized in that the process comprises using a cleavage method or a very-high-vacuum vessel to form on a substrate with different types of III-V-group semiconductor materials mixed thereon by means of the heteroepitaxial process such as the MBE or MOCVD process, a self-assembled film of the molecules having thiol groups in a non-oxidized area and then forming on an oxidized surface a self-assembled film of molecules having phosphoric acid group, trichlorosilyl groups or alkoxylyl groups.
