摘要： PROBLEM TO BE SOLVED: To secure a sufficient filtration area and a space for housing matter trapped by filtration, without enlarging the external size of an internal combustion engine. SOLUTION: In a lubricating device for an internal combustion engine, in which oil stored in a lubricating oil tank 1 is pumped up by an oil pump 2 and pressurized, large foreign matter is filtered by a main filter 3, and oil allowed to flow into an oil gallery 5 of a lubricating oil passage is distributed to respective parts 6 of an engine and returned to the lubricating oil tank 1, a bypass filter 4 arranged by being branched from an oil path before or after the main filter 3, and for removing fine foreign matter incapable of being removed by the main filter 3 is formed in the lubricating oil tank 1.

摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive lubricating oil suppressed in scattering into the surroundings and waste liquor pollution by adding to a non-water- soluble oil a solidifying substance that converts the non-water-soluble oil into a gel at a specified or lower temperature and converts the oil into a solid at above the specified temperature. SOLUTION: The non-water-soluble oil used is a mineral oil or a vegetable or animal oil. Among them, a vegetable oil comprising rapeseed oil is desirable. The solidifying substance used is desirably 12-hydroxystearic acid or N-lauroyl- L-glutamic acid α,γ-di-n-butyramide. It is desirable to add at least 5 wt.% solidifying substance. The lubricating oil is heated to a specified or higher temperature, fed into a workpiece and/or a tool and cooled to below the specified temperature to effect its gelation and adhesion. It is desirable that a white substance and/or a brilliant substance are added to the lubricating oil so as to make it possible to control the amount of feed on the basis of a whiteness or glossiness varying with a coating thickness.

摘要： PROBLEM TO BE SOLVED: To improve a sterilization force, eliminate any bad effect to a work piece or a machine tool, and reduce load to a work environment or a nature environment, by adding a sterilization reinforcement composed of an alkaline metal salt of organic acid and an electrolyte for providing electric conductivity to an oil solution, and impressing direct current voltage on the oil solution to perform electrolysis of the sterilization reinforcement. SOLUTION: An alkaline metal salt of organic acid as a sterilization reinforcement is easily solved in water but has a weak sterilization action. Therefore, direct current voltage is impressed on an oil solution to which the sterilization reinforcement composed of the alkaline metal salt of organic acid and an electrolyte. Then, current flows through the oil solution to perform an electrolysis of the sterilization reinforcement, alkaline metal is deposited on an electrode to instantly become metal hydroxide. While, separated organic acid becomes 'acid' having strong sterilization action to provide excellent sterilization performance. By performing such sterilization method, off-flavor caused by putrefaction is prevented from occurring in an environment surrounding the oil solution, and the environment is kept clean. Accumulation of fungus products are prevented from causing degradation or alteration of the oil solution.

摘要： PROBLEM TO BE SOLVED: To remove fine contaminates at a low cost and satisfactorily regenerate waste oil such as spent automotive engine oil by impregnating the network of a three-dimensional network structure to be formed of an oil gelling agent, with the waste oil to gelatinize it and pressing this oil gel. SOLUTION: An oil gelling agent is a chemical compound which forms a three-dimensional network structure in oil and sets (gelatinize) the oil. For example, a 12-hydroxystearic acid, dibenzylinden sorbitol, an amino acid gelling agent or the like can be used as the oil gelling agent. For the spent oil, spent automotive engine oil, spent transmission oil, spent gear oil or the like is used. The oil gelling agent is impregnated with the waste oil and this impregnation is heated and cooled to be gelatinized. Further, this oil gel is pressed into a regenerated oil. In this case, oil molecules are separated from the network structure under the pressing effect but a fine solid foreign matter or a fine deteriorated oil material contained in the spent oil is captured by the network structure and is left over. Consequently, it is possible to obtain a low viscosity and transparent regenerated oil.

摘要： PROBLEM TO BE SOLVED: To prevent sludge sticking to a filter surface part from being compacted. SOLUTION: A filter 2 consisting of a separation film having numberless fine holes is provided in the mid-way of a fluidizing path 5 of liquid. A vibrator 1 is provided in a non-contact state with the filter 2 on the upstream side of the fluidizing path 5 of lubricating oil 8 being in the neighborhood of the filter 2. The vibrator 1 is vibrated in a state of frequency having a lower value than that of ultrasonic vibration and having >=0.05μm value in amplitude. By vibration of such vibrator 1, the sludge 9 present in the neighborhood of the surface part of the filter 2 is unfastened and is evaded from the compactification. Thus, a filtering function of the filtering device can be adequately exhibited.
