Title: High voltage generating device for electron microscope
Inventor: SATO YUJI
IPC: H01J37/248
Filed: 1987-02-09
Abstract: PURPOSE:To detect a discharge starting voltage so as to prevent undesired discharge due to application of an excessive voltage by providing a means for controlling a voltage application means interlocking with a discharge detecting device. CONSTITUTION:When an aimed voltage Vs is applied, data is sent to a voltage application means 2 such as a digital-analog converter from a microcomputer 1 so that a voltage is raised at every step of several hundreds of V for several hundreds of mus from a voltage which is made smaller by ten percent than the aimed voltage Vs. The voltage application means 2 outputs a voltage in accordance with this data. A differential amplifier 3 is operated by this output voltage and a feedback voltage applied through a high resistance 7. A d-c voltage of several tens of V, which is outputted from the amplifier 3, is turned ON/OFF by switching transistors in a primary transfer circuit 5 so that a d-c high voltage is generated at a high voltage transformer 6. Since the high voltage is thus used stably from the aimed voltage Vs, large discharge can be prevented and the high voltage can be stably supplied.

Title: Method for copying transparent original plate
Inventor: MAENDL MATTHIAS DR
IPC: G03B27/80
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To lower the visibility of halo by executing a producing process so that second light/dark transition is shifted with respect to first light/dark transition when a mask is superposed on an original plate or the image of the original plate. SOLUTION: This method includes the process for producing the mask provided with the second light/dark transition corresponding to the first light/dark transition. This producing process is executed so that the light/dark transition of the mask is shifted with respect to the light/dark transition of the original plate when the mask is superposed on the original plate or the image of the original plate. In the case that the original plate is provided with a dark area, the mask producing method is executed so that the light/dark transition of the mask is superposed on the dark area of the original plate when the mask is superposed on the original plate or the image of the original plate. That means, the last mask stored in a memory 13 is superposed on the image having original luminance by a masking device 14.  Then, intensity values with respect to the respective points of the image having the original luminance are multiplied by an intensity value with respect to the point corresponding to the last mask in the memory 13.

Title: Image pickup type object extracting device
Inventor: HAYASHI MASAHIKO
IPC: G06T1/00
Filed: 1986-02-10
Abstract: PURPOSE:To enable a bit of image pickup picture information to eliminate a noise component in a highlight area, etc., by performing an arithmetic operation for a level difference between two image pickup picture signals outputted separately to a wave length band area of specified color, and to a second wave length band area not including the above wave length band area. CONSTITUTION:An image pickup signal S1 separated with the first color filter 2a becomes a bit of picture information including both of a bit of information corresponding to the color of an object fruit A, and a bit of information corresponding to a highlight area B. Also, an image pickup picture signal S2 separated with the second color filter 2b includes the highlight area B, but does not include the bit of information of the object fruit A. Therefore, by performing the arithmetic operation of the difference between the image pickup picture signals S1 and S2, a bit of picture information corresponding to the highlight area due to natural light or reflected light, etc., which are impossible to be separated independently by the filter 2a or 2b is eliminated. And a picture signal S3 that is corresponded only to the color of the object fruit A can be obtained. Furthermore, the binary-coded signal D of the bit of picture information from which an area corresponding only to the object fruit A in which the signal S3 is binary-coded based on a set threshold value ref and the noise component is eliminated, is extracted, can be obtained.

Abstract: PURPOSE:To use an optical fiber for an optical switch, etc., by varying the quantity of light transferred when the optical fiber is bent, by providing the internal wall part of the optical fiber at a prescribed part with the property of absorbing or scattering light. CONSTITUTION:The internal wall of an optical fiber is provided with a light absorbing part 3 or light scattering part at a prescribed position. When light passes through the optical fiber, a beam like a beam 4 parallel to the internal wall is all transmitted before the optical fiber is bent, a beam 5 incident at some angle is absorbed by the light absorbing part 3, and a beam 6 incident at a small angle is transmitted while avoiding the light absorbing part 3. When the circumference of the light absorbing part 3 is bent, the light beams 4, 5 and 6 are all absorbed by the light absorbing part 3 and not transmitted. For this light absorbing part 3, a mixture of a material having optical refractivity close to that of a core part 1 and light absorbing pigment is used. Measuring the attenuation of light by using this optical fiber enables the measurement of the curvature, etc., of a rail.

Abstract: PURPOSE:To improve the quake resistance of structure by a structure wherein the vibration damping device fitted in diagonal member such as diagonal bracing or the like in the frame of the structure is made up of a plurality of rotating discs, high viscous meterial filled between said discs and link bars moving said discs relatively. CONSTITUTION:A pair of two plates of circular discs 2 (2a and 2b) are employed and a pair of the link bars 1 (1a and 1b) with an equal length are arranged to these discs in such a manner that the bisector of the angle made by the center lines of the link bars 1 passes through the center O of the discs 2.
