Title: Apparatus for method for stabilizing system
Inventor: TERAO YASUHIKO
IPC: H02J3/24
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To grasp with accuracy a phenomenon of a power system leading to vibration divergent without installing any special filter, by judging that the power system will lead to vibration divergent when the result of comparison by a comparing means indicates in a specified cycle that the reactive power exceeds a reference value. SOLUTION: A vibration divergent detector 31 of a power system 1 judges whether the power system 1 and a power system 2 will lead to vibration divergent based on a fault which occurs in the power system 1 (2). Specifically, a reactive power measuring instrument 32 measures the reactive power Q1 passed through a linkage line 3 based on the current I1 detected at CT9 and the voltage V1 detected at PT10. When a reactive power Q1 is output from the reactive power measuring instrument 32, a vibration divergent judging instrument 33 compares the reactive power Q1 with the reference value, and judges every cycle of the vibration of the reactive power Q1 whether the reactive power Q1 exceeds the reference value. If the reactive power Q1 exceeds the reference value every cycle of the vibration of the reactive power Q1 , it is judged that the power systems 1, 2 will lead to vibration divergent.

IPC: H01P3/08
Filed: 1991-03-18
Abstract: PURPOSE:To enlarge the inductance value of an inductance part without prolonging it by partially differing the thickness of a dielectric substrate. CONSTITUTION:On the surface of a dielectric substrate 11, a micro-strip line 12 is formed while alternately arranging wide parts 12a and narrow parts 12b and defining the both ends as intermediate width parts 12c between the wide parts 12a and the narrow parts 12b. The wide parts 12a constitute a parallel capacitance part 13 as open stubs, and the narrow parts 12b constitute an inductance part 14 as high impedance lines. The dielectric substrate 11 formed the microstrip line 12 on the surface is fixed to a ground conductor 15.

For the ground conductor 15, an uneven shape is formed corresponding to the uneven shape of the dielectric 11, and the both are adhesively fitted. Therefore, although the inductance of the inductance part 14 is short, the specified inductance can be enlarged as a whole by making it thick.

Title: Fixing unit for image forming device with parallel paper supply function
Inventor: KISHIGAMI MINORU
IPC: G03G15/20
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide the fixing unit of an image forming device with a parallel paper supply function constituted so that parallel paper supply can be executed without causing fixing wrinkles. SOLUTION: When single paper supply is selected in order to execute copying processing, a first halogen lamp 150a is energized and a fixing roller 150 is uniformly heated as a whole while keeping an inverted-crown shape. When parallel paper supply is selected, a second halogen lamp 150b is energized and the temperature around the central part of the roller 150 is partially raised. When the part around the center of the roller 150 is heated and expanded because of the partial temperature rise, the outside diameter of the part around the center of the inverted-crown-shaped roller 150 is enlarged and two inverted- crown shapes are formed on the shaft of the roller 150. When the parallel paper supply is executed, speed difference is produced at the shaft-direction central part and the end part of the parts of the inverted-crown shapes when paper passes through the parts of two inverted-crown shapes. Thus, the fixing wrinkles are prevented from occurring.
