Filed: 1981-07-07
Abstract: PURPOSE:To remove impurities, e.g. sulfur or nitrogen oxides, efficiently even from an engine oil containing an additive for prefenting the premature deterioration, by adding a polyhydric alcohol to a lubricating oil, and passing a DC current across two electrodes. CONSTITUTION:An engine oil is introduced from an inlet 8 of a cover 5 and a central hole (10a) of the top insulator 10 into the inner electrode 3, made to flow in an oil purifying bath 2 and then flow from an outlet 9 and hole (10b) to the outside of an electrostatic oil filter 1. A DC current is made to flow from the inner electrode 3 (negative electrode) through the engine oil to the oil purifying bath (positive electrode) 2, and the temperature of the oil is increased to dissolve a polyhydric alcohol, ethylene glycol, impregnated into a collecting material 20 into the oil and distribute uniformly in the oil. Thus, impurity particles charged negatively with electricity are made to flow to the positive electrode 2 and adhere to the inner peripheral surface of the collecting material 20.

IPC: H01L41/22
Filed: 1984-05-29
Abstract: PURPOSE:To inhibit the adverse effect of background noise beams minimally, and to detect a defect at a high S/N ratio by revolving a laser-beam projecting means at an arbitrary angle around an optical axis while mounting a polarizing plate, which can be turned at an arbitrary angle around the optical axis and forming a pin hole, a diameter thereof can be adjusted, to an optical system. CONSTITUTION:Since a wafer consisting of LiTaO3 has peculiar polarizing characteristics determined at every lot by the optical properties of a granular single crystal and has characteristics of which scattered light by a foreign matter increases on a projection by the plane of polarization in the specific direction, a laser oscillator 4a is turned, the position of an angle where scattering by the foreign matter is maximized is investigated experimentally, and the angle is fixed. When a polarizing plate 4b is rotated to adjust the amount of light, a point where a minimum foreign matter to be detected can be detected with difficulty is searched and the angle is fixed, an approximately maximum S/N ratio is acquired. The diameter of a pin hole 3d is adjusted, and a field to background noises is narrowed. To be concrete, the maximum S/N ratio is obtained when the field is narrowed up to the extent of the size of a defect to be detected with due regard to the size of the defect.

Filed: 1982-06-23
Abstract: PURPOSE:To set the conditions optimum for cooling of an ingot under a continuous casting mold in a short time with preparation of some sample in the above-described cooling, by determining the optimum values of the temps. in the non-worked and worked regions of the ingot through tension test with the ingot sample of the same steel kind. CONSTITUTION:In is necessary to maintain the temp. in the bent part of an ingot and the thermal hysteresis to attain said temp. in order to prevent the transverse crack of the ingot, and these temps. are represented by the ingot temp. T2 in the bent part and the lowest ingot temp. T1 right after the casting mold. Thereupon, a sample of the same steel component system as the steel kind intended for preventing transverse crack is heated to the melting temp. and is then cooled to and kept at the temp. T1. While the sample is reheated and kept to and at the temp. T2, the sample is subjected to a high temp. tension test, and such temp. regions of T1 and T2 at which the drawing value attains >=50% are determined. Since the shape of the test piece in this stage has a smaller influence on the drawing value as compared to the temps. T1, T2, an ordinary shape, for example, a round steel shape is satisfactory, and the above-mentioned time for holding the sample is allowed to approximately coincide with the time when the ingot receives heating in an actual machine.

Filed: 1983-06-17
Abstract: PURPOSE:To input easily and accurately a position in a short processing time by directly inputting a position on a picture by a coordinate position input device, and correlating the positional information with an inputted Japanese word. CONSTITUTION:A word cutting out means 5 cuts out a word from a Japanese character string encoded into characters by a Japanese word input means 1 and, at the same time, sends the word to a position correlating means 6 as data (a) by adding a flag bit ''1'' when the word is a demonstrative pronoun indicating a position or another flag bit ''0'' when the word is not the demonstrative pronoun. On the other hand, a coordinate position input means 7 sends an inputted coordinate (b) of a position on a picture in the form of x- and y-coordinates to the means 6 after encoding them into characters. The means 6 stores the data (a) and (b) in a word memory and coordinate position memory, respectively, and, when the flag bit of the word of the data (a) is ''1'', sends the character- coded x- and y-coordinates to a Japanese word analyzing means 3 instead of the word. When the flag bit is ''0'', the means 6 sends the word to the means 3 as it is. The means 3 decodes an input signal (c) and displays the decoded result through a display device 4.
