Title: Dummy waveform generating circuit
Inventor: FUKUDA KAZUYUKI
IPC: H03K4/94
Filed: 1987-06-25
Abstract: PURPOSE: To reduce the number of resistances and to eliminate the influence of temperature characteristics and improve waveform accuracy by providing a 1st generating means which increases or decreases in its current value with an input, a 2nd current generating means which generates a constant current when the input exceeds a specific value, and a converting means which converts the composite current of currents of both current generating means to a dummy waveform.  
     CONSTITUTION: A voltage and current converting circuit 30 which generates a 1st current I 1  with a linear functional increase or decrease tendency corresponding to the input voltage VIN. A voltage and current converting circuit 40, on the other hand, generates a 2nd current I 2  which increases or decreases with the input voltage VIN similarly to the 1st current I 1  up to a threshold voltage Vt as a constant reference voltage and becomes constant after the input voltage VIN reaches the threshold voltage Vt. Those currents I 1  and I 2  are summed up on the input-side line of a current mirror circuit 52 as the current converting means. Then the respective values R 1 ∼R 3  of resistances 36, 50, and 54 are set optionally to obtain a desired dummy sin wave, thus obtaining the high-accuracy dummy waveform with a small number of resistances.

IPC: B01D35/06
Filed: 1979-12-08
Abstract: PURPOSE: To efficiently remove the impurities in industrial oil by applying a magnetic field to the industrial oil by means of an electromagnet using a specific DC  power source to make metal powder into positive-charged bodies and other inorg.  fine particles to negative-charged bodies and electrostatically flocculating and  coarsening both.  
     CONSTITUTION: Waste oil such as lubricating oil contg. a large amount of iron powder and lime powder is led to a tank 7, and is flowed as oil component flow A from an overflow tank 6 into a device 1. If a magnetic field of 1,500W5,000 gauss is acted upon an electromagnet 12, it turns out that ferromagnetic materials such as  iron move in the magnetic field and this generates eddy current in fine particles,  due to which iron powder 29 and inorg. fine grains 27 become positive- and negative-charged bodies and electrostatic floc 28. These become the oil component flow  D on account of the magnetic force of a permanent magnet 16 and gravity. The oil  component flow C flows as supernatant into a purifying tank 20. The oil component flow D is further accelerated of the sedimentation rate of the electrostatic  floc by the action of the electromagnet 18 having the magnetic force about twice  that of the electromagnet 12.  The purified oil is led from the discharge ports 21, 24  of the purifying tank 20 and settling tank 14 through pipes 22, 25 into a tank 23.
