摘要： PURPOSE:To obtain a power steering fluid having an excellent anticorrosive effect by incorporating an alkylated or phenylated (thio)phosphoric acid compound, a specific thiadiazole derivative, and calcium salicylate into a base oil. CONSTITUTION:An alkylated or phenylated (thio or dithio)phosphoric acid compound (A) (the phenyl may be alkylated), is incorporated in an amount of 0.005-2wt.% into a mineral or synthetic base oil together with 0.05-1wt.%, preferably 0.05-0.15wt.%, thiadiazole derivative (B) represented by formula I (wherein R1 and R2 are each a 1-12C alkyl) and 0.1-6wt.% calcium salicylate (C), e.g. the one represented by formula II (wherein R, is an 8C or higher, preferably 14-20C alkyl and N is OH or O-Ca-OH) to obtain a hydraulic oil for power steering use only. The ingredient (A) serves to improve frictional properties, and the ingredient (B) serves to prevent metal corrosion. The ingredient (C) contributes especially to the prevention of bearing metal corrosion and imparts desirable properties required to a power steering fluid.

摘要： PROBLEM TO BE SOLVED: To obtain a fluid composition capable of inhibiting dissolution of copper in a working fluid by blending a base oil selected from among mineral oils and synthetic oils other than silicone oil with a phosphate-based compound and a 2-alkyldithio-5-mercapto-1,3,4-thiadiazole compound.
SOLUTION: At least one compound (A) selected from among an alkyl or alkyl-substituted or unsubstituted phenyl phosphate compounds, alkyl or alkyl- substituted or unsubstituted phenyl thiophosphate compounds and alkyl or alkyl- substituted or unsubstituted phenyl dithiophosphate compounds other than metal salts is blended with at least one of 2-alkyldithio-5-mercapto-1,3,4-thiadiazoles (B) of the formula (wherein R
1 is a 1-12C linear or branched chain alkyl). The amount of the component A blended is about 0.005-0.5 mass % in terms of phosphor and the component B, about 0.02-1 mass%.

摘要： PURPOSE:To save time for, and to rationalize a method of, calculating control input for an automobile engine, by detecting an indirect operational parameter, such as a flow rate of air, and calculating a control input concerning a feed rate of a fuel in accordance with a predetermined method. CONSTITUTION:In the automobile engine, for example, a Karman's sensor is used for detecting the flow rate of air by counting the number of vortexes per one revolution of the engine. The drawing shows the wave-form of an output from the Karman's sensor. As may be noted from the drawing, the flow rate of air is in inverse proportion to a frequency, i.e. a period ti. A circular mark denotes an instance at which the fuel is ejected, the ejection of fuel occurring once a revolution of the engine. An average value of the ti can be expressed by a formula, Ti=Ti-1+ alpha(ti-Ti-1)+..., wherein alpha is a coefficient not greater than 1. The right member of this formula is rewritten by a successive method as ti(i=1,2,...) and calculation is made by means of a microcomputer. Accordingly, the calculation time can be saved, and the calculation method can be rationalized.
