Abstract: PURPOSE: To measure microorganisms by a method wherein microorganisms marked by fluorescent light by using anti-body-antigen reaction are exposed to ultraviolet rays, and the amount of excitation light produced is electrically measured.  
     CONSTITUTION: Fluorescent anti-body-antigen 4 obtained by bringing the sample microorganisms into contact with their fluorescent light-marked antibodies are exposed to ultraviolet rays of wavelength L 1  from light source 1 via amplifier 2 and spectroscope 3. The resultant excitation light L 2  is analyzed by spectroscope 5, and light L 3  of a specified wavelength is taken out. This is electrically measured by meter 7 via amplifier 6. Next, the microorganisms which have been measured by a conventional method (such as dry bacteria weight conversion) in advance and their measurement is known are measured by using the measurement line obtained by the above-described method and thereby the sample organisms are quantitatively measured. The above-described antibodies are formed by injecting the sample microorganisms into the blood of a vertebrate (rabbit, for example) and dyeing and marking the antiserum produced in the blood with a fluorescent pigment.

IPC: F02B67/06
Filed: 1991-03-13
Abstract: PURPOSE:To prevent the occurrence of surging by attaching a cam operation control mechanism for releasing the moving action of a movable pulley caused by a cam mechanism when a throttle of an engine is closed to lower the rotating speed of a driven side pulley and a supercharger and the outlet pressure of the supercharger. CONSTITUTION:When a throttle is opened, an electromagnet 45 of a cam operation control mechanism 29 is excited to attract an attraction member 41, so that a pin 43 is engaged with a slit 39 of a cylinder 31 in a cam mechanism 27. Accordingly, the torque of a driving shaft 15 is transmitted through the pin 43 to the cylinder 31, so that a cam pin 37 engaged with a cam groove 33 and a movable pulley 19 are moved toward a fixed pulley 17. Thus, the movable pulley 19 and the fixed pulley 27 are pressed to the right and left sides of a belt 13 to prevent slippage of a belt 13. When the throttle is closed, the electromagnet 45 is de-magnetized so that the attraction member 41 is returned by a return spring 47. Accordingly, the movable pulley 19 is made recede from the fixed pulley 17, so that the driven side pulley and a supercharger are rotated at low speed.
