PURPOSE:To continually obtain an operative condition of minimum rate of fuel consumption, by calculating the rate of fuel consumption in three conditions of different speed change ratio through a switch control and correcting the actual speed change ratio so that the speed change ratio obtains the minimum value of the calculated rate of fuel consumption. CONSTITUTION:A target speed change ratio ar...

PURPOSE:To minimize a rate of fuel consumption, by measuring the rate of fuel consumption before and after speed change ratio is changed while repeating this measuring action in plural times and correcting a speed change ratio correction value so as to obtain the speed change ratio in which the minimum fuel consumption is attained. CONSTITUTION:A target speed change ratio arithmetic part 210 calcu...

PURPOSE:To enable a clutch to smoothly perform its gentle engagement, by repeating on-off operation of the electromagnetic clutch in a short period and increasing a proportion of the on-time for the off-time. CONSTITUTION:A microcomputer 26 outputs a required signal, corresponding to input signals of an overheat switch 31, hydraulic pressure switch 32, charge switch 33 and a steering acting angle ...

Redispersible powders are obtained from an aqueous dispersion of a polymer built up from 20-60% of acrylic or methacrylic acid and 40-80% of alkyl esters of acrylic or methacrylic acid and having a minimum film-forming temperature (MFT) of below 60 degrees C and a dynamic freezing point (T lambda max) of the polymer of below 150 degrees C by spray drying at an inlet temperature Ti and an outlet te...

The stages of the method which are to be carried out manually are extremely simplified and the degree of utilisation of the blank prior to cutting can be determined objectively and weighed up against the subjective feeling of the suitable selection of the structure. When cutting patterned materials, it is also guaranteed that the pattern on the part to be cut out has been selected in a simple mann...

A support for a biomedical implant device in which the support has a surface layer composed of a biocompatible calcium phosphate material such as sintered hydroxyapatite with a porosity of 50-60% and pore size of 0.5-500 micrometers. Preferably, the surface layer is formed with projections or recesses of a few hundred micrometers size.

PURPOSE:To prevent the reduction of efficiency of heat transfer due to the ash in a furnace, the corrosion of heat transfer pipes, and dirtiness in the furnace by a method wherein coal is converted into combustible gas in a fixed bed gasification furnace and the gas is supplied to the furnace to be burnt. CONSTITUTION:Introduction of combustible air into a gasification furnace 12 from under a rota...

PURPOSE:To improve the rigidity of a rear seat and to ensure its head clearance of passengers, by constituting the rear seat of a rack-shaped seat surface part, continued to a floor part, and a vertically rising wall-shaped back-leaning part and forming the seat surface part to an almost spherical shape being recessed to the bottom. CONSTITUTION:A rear seat 6 is constituted of a rack-shaped seat s...

Chemically resistant materials having high initial and final strengths are based on a combination of water-soluble silicates (component 1) and calcium aluminates or aluminate cements with or without additives (component 2) and water. In the first hardening phase of the mixture of components 1 and 2, solid reactive calcium hydroxide Ca(OH)2 is added in a quantity which is within the range between 0...

PURPOSE:To make it possible to coat adhesive by the mechanically enough amount and consequently remove the scattering in performance and improve the durability of a part by a method wherein the surface of thread groove, which is formed on the inner surface of a metallic tube, is gradually covered from its upper part by the adhesive and, after the drying of the adhesive, green rubber is filled in t...
