Title: Method of controlling inverter
Inventor: SATO SHINJI
IPC: H02M7/48
Filed: 1988-03-03
Abstract: PURPOSE:To decrease distortion in a wide region of frequencies by forcibly setting a carrier for every 60 degrees. CONSTITUTION:A load 4 is driven through a DC filter capacitor 2 and an inverter 3 from a DC power source 1. This inverter 3 constitutes its control unit of a signal generator 5, integrator 6, output waveform reference creator 7 and a carrier generator 8, and a PWM instruction is given to the inverter 3. Here a carrier setting signal generator 9, correction signal arithmetic unit 10 and a waveform reference corrector 11 are provided. This generator 9 alternately outputs a +1 and -1 carrier setting signal for every 60 degrees of electric angle setting by this code the carrier generator 8 to +1, 0. Here because a carrier generally jumps in its phase, a correction is performed in a manner wherein an instruction in that section agrees with the duty of a pulse. Now possessing both the merits of synchronous pulse width modulation(PWM) and asynchronous PWM, output voltage distortion is decreased in a wide frequency region.

Title: Vector map flattening and trapping
Inventor: YHANN STEPHAN
IPC: H04N1/58
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To trap a page automatically without requiring a large scale memory or a processor resource by defining one page with a tile and processing each tile based on a vector map display thereby determining the intersection of the outline segment of a polygon. SOLUTION: Intersection of a segment defining the outline of an object means that an edge segment is concealed not to be printed. Trapping can be applied only to edge segments not concealed. In the vector representation of a tile shown on the drawing, it an be determined that only two hatches cells (3, 4), (4, 4) have more than one edge and the edges in the remaining cells have no intersection. When the tile is represented by a vector, intersecting outline segments can be determined without requiring an intricate data processing or a large scale memory.

Abstract: PURPOSE:To absorb a thrust vibration generated at a rotor shaft by mounting a buffer material between a bearing and a bracket. CONSTITUTION:When a buffer material 13 is provided between a bearing 12 and a bracket 14, the bearing 12 contacted with the material 13 is not rotated. Thus, no heat is generated, and a thrust vibration transmitted to the bearing 12 can be absorbed and attenuated. The bearing 12 becomes hardly movable as compared with that having no material 13, but when the bearing 13 is necessary to move, it is only when the resistance of engaged shaft immediately after assembling is alleviated. If an external force is applied slightly, it is eliminated, almost no possibility of moving occurs at the normal using time to cause no problem.
