Title: Modulation device of pwm inverter
Inventor: SHIBAMOTO MASAHIKO
IPC: H02M7/48
Filed: 1978-09-20
Abstract: PURPOSE: To decrease the transient variation of the output of an inverter in case of the change-over of triangular waves, by preparing a plurality of triangular-wave generators with different frequency, and by changing over the triangular waves by selecting one of the triangular-wave generators by means of a change-over circuit.  
     CONSTITUTION: The square-wave output of an oscillator 1 is supplied to a frequency demultiplier 2 while being fed to frequency demultipliers 11∼13 of different three kinds. The output of each frequency demultiplier is severally sent to corresponding triangular-wave generators 14∼16, and each generates triangular waves with frequency several times as many as the output frequency of triangular-wave generators 4. When the each triangular-wave output is supplied to a change-over circuit 20 through corresponding amplifiers 17∼19, any one triangular wave is selected in response to signals that change over the triangular waves, and put out. One triangular-wave output selected is fed to a multiplier 10, controls an inverter 8 and generates three-phase sine wave-like constant-currents.

Title: Float pump
Inventor: ITOU TAKASHI
IPC: F04D13/00
Filed: 1979-09-06
Abstract: PURPOSE: To make smooth the flow-in of oil or dust and stabilize a pump operation by providing a body of float and suction passage constituted double-conically.  
     CONSTITUTION: On the outer periphery of a body 1 of float and suction passage is provided a passage part 1d, while on the upper surface thereof is provided a space part 1e for buoyancy. The floatng oil or dust is sucked together with water by rotating a blade wheel 4 by a motor 3 and is transferred from a discharge hose 7 to a fixed place thrugh the route shown by an arrow. The passage part 1d is composed of pipes of large diameter positioned at an appropriate interval and thus the flow-in velocity at flow-in ports is slow. Therefore, the continuous and smooth flow without interruption is obtained even when the oil and dust, transferring on the surface of the water, come to the flow-in ports at a low speed. Although the velocity of flow is ordinary at an opening part 1f, the flow-in of air does not occur since the velocity of flow at the flow-in ports is slow and there exists a lower conical body 1b. In addition, excellent stability is obtained since a float body is of large diameter.

Inventor: INOUE DAISUKE
IPC: C23C14/48
Filed: 1992-04-07
Abstract: PURPOSE:To suppress electrifying conductive dust so that the dust may be prevented from being transferred between every two ion beam drawer electrodes to lessen any opportunity of causing electric discharge by laying insulating films respectively on both or either of the mutually opposed faces of the ion beam drawer electrodes that draw out ion beams. CONSTITUTION:Insulating films 8 made of silicon nitride are laid respectively on both or either of the mutually opposed faces of every two of accelerating electrodes 2, decelerating electrodes 3 and earthing electrodes 4 respectively juxtaposed with one another. As a result of that, each of the insulating films 8 can suppress electrifying conductive dust so that any possibility of shuttling the conductive dust between every two electrodes may be lessened to lessen any opportunity of causing electric discharge even if a conductive target-material attached to each of the electrodes is peeled from the electrode to form the conductive dust by film stress. This can eliminate a problem of abnormal heating caused by applying ion beams to an object other than a target and the cause of contamination so that any possibility of striking ions against the decelerating electrodes and the earthing electrodes may be lessened to lengthen the life of each electrode.
