Title: Laser projection microscope
Inventor: BATENIN V M
IPC: G02B21/00
Filed: 1998-03-25
Granted: 2001-01-27
Abstract: FIELD: quantum electronics, laser projection systems. SUBSTANCE: laser projection microscope can be used for non-destructive test of large integrated circuits, for inspection of processes of treatment of materials with concentrated energy fluxes in industry, for examination of microobjects in medicine and biology. It has laser amplifier, objective lens, TV camera matched with computer placed coaxially. Image of observed object is formed on receiving unit of camera with the use of image forming system. Image forming system can include three lenses. First and second lenses are rigidly fixed relative each other so that rear focus of first lens is matched to front focus of second lens, third lens is made fast with regard to receiving unit of image recording system. Distance l 1  from observed object to first lens is chosen from condition l 1 >(f 1 +f 2 )×f 1 /f 2 , where f 1  and f 2  are focal distances of first and second lenses accordingly. With movement of observed object along optical axis image of object of observation is displaced after second lens and distance from it to third lens changes. By movement of system of first and second lenses with reference to third lens this distance is brought to initial state, that is size of image of observed object on receiving unit of TV camera is also brought to initial position. Required displacement of system of first and second lenses is strictly proportional to displacement of object of observation with proportionality factor K = (f 2 /f 1 )/(1-(f 2 /f 1 )). EFFECT: preservation of stable size of image of observed object on receiving unit with change of its position along optical axis and consequently increased accuracy of test. 2 dwg

Title: Method for switching alternating current by symmetrical switching elements (variants)
Inventor: CHEKHET EDUARD MYKHAILOVYCH
Filed: 2001-03-22
Abstract: According to the present invention, a method for switching alternating current by symmetrical switching elements in an electric converter with the number of input phases no less than three is proposed. Each of the switching elements contains two gates, which conduct current in opposite directions. The proposed method consists in that the switching of the load current from an input phase circuit to another one is accomplished at several stages, using the corresponding switching elements. At the first stage, one of the gates of the closing switching element is rendered conducting so as to prevent the short-circuit current between the first and the second phase circuits under existing relationships between the amplitudes and polarities of the corresponding phase voltages. At the second stage, the gate of the opening switching element that conducts current in the same direction as the said first gate of the closing switching element is cut off. At the third stage, the second gate of the closing switching element is rendered conducting. At the fourth stage, the second gate of the opening switching element is cut off. If there is the need to close one switching element and open the other switching element, when these switching elements are connected to the different converter input phase circuits for which it is impossible to determine the existing relationships between the amplitudes and polarities of the corresponding phase voltages, the intermediate switching of the load current from the phase circuit with the closing switching element to the third or the other next phase circuit with maximal phase voltage value is accomplished, using the corresponding switching elements, and then the switching element for connecting to the required phase circuit is rendered conductive, using the above mentioned gate switching operations. The proposed method can be employed for switching current in a converter with three input and three output phase circuits, in which pulse-duration modulation is provided by summing a number of zero and nonzero input voltage vectors within each cycle of pulse-duration modulation, when the cycle of the converter input voltage is divided into six intervals that are separated from each other by the points in which the polarity of the input phase voltages changes. In such a converter, for generating nonzero voltage vectors, two line voltages are used, which values exceed the value of the third line voltage. The generation of zero voltage vectors is provided by concurrently closing all the switching elements connected to the input phase circuit, which voltage value is maximal and polarity differs from that of the other two phase voltages within the given cycle of the converter input voltage.
