Title: Steel member coated with rust-proof resin cured by ultraviolet ray
Inventor: OKITA MASAKAZU
IPC: B32B15/08
Filed: 1987-06-23
Abstract: PURPOSE:To improve the adhesion of a coat and the corrosion resistance of a product by coating a product with the rust-proof resin, cured by ultraviolet ray, containing a specified amount of colorless transparent glass powder. CONSTITUTION:The reason why colorless transparent glass powder is contained in resin is that higher permeability to ultraviolet ray than that in the case when colored or opaque glass is used. The glass is powdered for being mixed uniformly with resin and dispersed therein. When the amount of glass powder is less than 5wt.%, the permeability to ultraviolet ray of that coat is low, and accordingly its coating property is almost the same with the coating property in the case when the paint containing no glass powder is only used, and its adhesion and corrosion resistance become inferior. The reason why its upper limit is 60% is that when the upper limit exceeds 60vol.%, its corrosion resistance is improved, but its adhesion becomes inferior. Further when the glass powder amount exceeds 60vol.%, the viscosity of the resin is heightened, and its coating operation becomes impossible. The shape of the particle of the glass powder may be any shape, but it is preferably the shape of a ball having no tendency of viscosity rising. The glass is preferably a hollow object, since the glass is apt to sink by the difference of specific gravity between the resin and the glass.

Inventor: EERITSUHI KURUTSU
IPC: B03D1/14
Filed: 1986-07-04
Abstract: Process and device for the flotation of fibre suspensions in one or more flotation cells. The suspension quantity to be purified is fed without aeration to the respective flotation cell. The fresh air injected in the bottom part by means of at least one aeration apparatus is utilized for the repeated washing out of the rotating pulp suspension, the amount of circulation required for aeration being greater than the new amount of suspension to be cleaned. The washing out in the individual washing stages proceeds in the co-current or counter-current process. In the last stage, the washing out is carried out using fresh air. After each washing stage, a complete degassing of the pulp suspension is carried out. In the case of more than twofold washing out, the circulation is carried out in the central washing out stages by means of weight difference between the aerated and degassed pulp suspension. In the case of plants having more than one flotation cell, the transport of the suspension from one cell to another cell proceeds by free fall. The flotation froth is conducted away at the surface of the cell.

IPC: H02H7/04
Filed: 1978-12-20
Abstract: PURPOSE: To provide the subject system wherein the interruption of a transformer is determined by a three-winding passing current of the transformer and a two-winding passing current except the components connected to a higher harmonic generating source, and further when the outputs of these currents given to an overcurrent relay assume interrupting directions, the transformer is interrupted thereby to prevent the erroneous judgment.  
     CONSTITUTION: A comparator 37 generates an output in the interrupting direction of the transformer from the vector sum of three-winding current of the transformer through a differential circuit 32 and a scalar sum circuit 33. From two winding currents except the component connected to a higher harmonic generating source, a second higher harmonic component is introduced through a differential circuit 31 and the like, and a comparator 36 generates an output in the interruption preventing direction depending upon the component. A coincidence gate 38 determines theinterruption in accordance with the outputs of both comparators. On the other hand, the outputs of differential circuits 32 and 31 are introduced in overcurrent relays having level detectors 40 and 39, respectively, and when both overcurrent relays produce outputs because of more than the predetermined values of said outputs of the differential circuits, a coincidence gate 41 generates an interruption signal. According to this arrangement, an erroneous judgement due to the transient current of the higher harmonic generating source connected to the terminal of the transformer can be prevented.
