Title: Electromotive force generator for composite magnetic substance
Inventor: MATSUSHITA AKIRA
IPC: H02N11/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To cause a generator to generate approximately constant large electromagnetic force by accumulating a large number of composite magnetic components composed by magnetically coupling fixed magnetic components having magnetic anisotropy and bistable magnetic components to each other, and forming a composite magnetic substance into a body. SOLUTION: The magnetic properties of fixed magnetic components have comparatively large coercive force and magnetic anisotropy in a positive direction. The properties of bistable magnetic components are comparatively small coercive force and one-axis magnetic anisotropy including the positive direction and negative direction. When an electromagnetic coil 14 is wound on a composite magnetic substance 13 composed by bundling a large number of composite lines 10 into a body, if a positive magnetic field 6r is interlinked next to a negative magnetic field 6s intermittently, each time each bistable magnetic component repeats magnetization reversal along with action of diamagnetism.  Though electromotive force E whose magnitude corresponds to the number of the bundled composite lines 10 is continuously generated in the electromagnetic coil 14 at this time, this is electromotive force based on autonomous high-speed magnetization reversal. Consequently, it is possible to induce electromotive force of approximately constant magnitude.

Title: Paper sheets handling mechanism
Inventor: UCHIUMI ITSUKI
IPC: B65H31/00
Filed: 1989-05-23
Abstract: PURPOSE:To enable it to accurately count the number of paper sheets even if stacking is continued in succession after jam handling by installing a conveying means which conveys the paper sheets entered in a conveying passage at the side where a paper jam occurred, to a stack part against the resistance force of the jammed paper sheets. CONSTITUTION:When a jam occurred, a jam detecting sensor 20 detects this jam occurrence, and a selector means 13 selects a conveying passage. With this changeover, such a possibility that paper sheets might be conveyed to the conveying passage at the side where the jam occurred is prevented. The paper sheets fed to the conveying passage at the side the jam occurred before this selector means 13 is selected are conveyed to a target spot by conveying means 15, 16 strong in conveying force against resistance of the jamed paper sheets. Consequently, the number of paper sheets being counted by a sheet count sensor 19 comes to show the number of the paper sheets fed to the conveying passage at the side where the jam occurred accurately.

Title: Excitation control device for synchronous generator
Inventor: KITAMURA SATORU
IPC: H02P9/14
Filed: 1987-05-27
Abstract: PURPOSE:To prevent a synchronous generator from tripping, by judging whether malfunction is due to the abnormality on a system side or due to the fault of an automatic voltage regulator in the generator and by changing over to other queuing system only when it is found to be the fault of the automatic voltage regulator. CONSTITUTION:An automatic voltage regulating device AVR 28 supplies the deviation signal between the terminal voltage of a synchronous generator 1 detected by a voltage transformer 6 and the set point to a thyristor 4 for excitation through a gate pulse generator 14. When the reactive power comes to the leading side in operating with the AVR 28 and gets to the activating level of a low excitation limiting device 9 and further to the activating level of a low excitation protection device 16, an abnormal signal is outputted. At this time, in case the variation of the terminal voltage of the synchronous generator is lowered, it is judged as a fault of the AVR 28 and a changeover circuit 12 is changed over from the AVR 28 to a field current control device 29. In case the variation of the terminal voltage goes up, an automatic follow-up system is locked.
