Abstract: A polyetheresteramide having good heat resistance, permanent antistatic property and superior compatibility with thermoplastic resins and a resin composition containing the polyetheresteramide are disclosed, wherein the polyetherester-amide consists essentially of a polyamide oligomer with carboxylic chain ends having a number average molecular weight between 200 and 5,000 and a bisphenol compound with oxyalkylene units having a number average molecular weight between 300 and 3,000. Antistatic resin compositions with good antistatic property and heat resistance are obtained from compositions comprising 3 to 40% by weight of the polyetheresteramide and 60 to 97% by weight of thermoplastic resins. The antistatic resin compositions can contain as compatibilizers vinyl polymers having functional groups such as carboxyl and epoxy groups or block polymers containing polyolefin blocks and aromatic vinyl polymer blocks.

Abstract: Resin compositions of improved dispersibility and mechanical properties are obtained by polymerizing a polymerizable compound (A), insitu in a melted thermoplastic resin (B), in the presence of a dispersant (C) reactive or compatible with at least one of the resin (B) and polymerizate of (A).Suitable dispersants include those represented by the general formula (1) or (2)R.sub.1 --L(X--M--X--L).sub.n X--M--R.sub.2 (1)R.sub.1 --L(X--M--X--L).sub.n --R.sub.2 (2)wherein R.sub.1 and R.sub.2 are groups, such as hydrocarbyl acyl, alkoxy, hydroxyl, mercapto, amino, epoxy, isocyanate, carboxylic, carboxylic anhydride, carboxylic halide and aldehyde groups; L and M are residues of a polymer having a number average molecular weight of about 500-about 3,000,000, the difference in solubility parameter between the residue L or M and the resin (B) or polymerizate of (A) being not more than 0.

Abstract: An inference system comprises an input part for entering data to be used for making an inference, a data storage part for storing data showing a possibility of a conclusion depending on the data entered from the input part, an inference part for making an inference by eliminating a degree of fuzziness of the conclusion by use of the data entered from the input part. And an output part for outputting the conclusion obtained from the inference part. The inference part converts the data obtained from the data storage part into Dempster-Shafer's basic probability assignment data in making the inference.

Abstract: A container capable of heating its content when ignited has a container containing Japanese sake, coffee, soup or the like and an exothermic material storage chamber projected into the container. A self-combustible exothermic material consisting of a mixture of oxidant such as potassium permanganate and a combustible material such as iron powder, ferrosilicon powder or the like is charged into an innermost portion of the storage chamber. A heat insulating layer made of inorganic porous material is disposed adjacent to the exothermic material and ignition means for igniting the exothermic material is extended from the exterior of the container to the exothermic material.

Abstract: A lubricant composition comprises as essential ingredients a sulfur compound and an oil-soluble molybdenum compound, obtained by reacting one or more of hexavalent molybdenum compounds selected from the group consisting of molybdenum polyoxide, molybdic acid and the alkali salt thereof or a compound prepared by reaction of the compounds and a reducing agent, with an amino compound represented by the general formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 which may be identical with or different from each other individually represent hydrogen atoms or hydrocarbon groups of 1 to 30 carbon atom. The lubricant additives comprising the novel molybdenum-amine complex and the sulfur-containing compound in combination are excellent in the anti-oxidation, anti-wear and friction-reducing effect and, particularly, excellent in view of the metal corrosion.

Abstract: A Roots type blower is disclosed having rotors with twisted-shape and projections on the pitch circle. The blower is compact in the axial direction, because the projections work as gearing between the rotors. Therefor, it is not necessary to provide additional gears for driving the rotors. Each of the rotors has a twisted-shape with a relationship of n.times..theta..gtoreq.2.pi., where n is the number of leaves and .theta. is the lead angle.

Abstract: An apparatus for controlling a supercharger driven by an engine or exhaust gas is controlled in response to primarily the changing rate of accelerator (pedal) position, and additional parameters such as time after supercharging start and/or vehicle speed and transmission gear shift position, etc. so that it can precisely respond to the acceleration requirements by the driver with good accelerating performance and fuel economy.

Abstract: A flow control apparatus for a brake master cylinder of a vehicle includes a valve chamber formed within a plug threadably secured to an outlet port of the master cylinder which is fluidically connected to the wheel cylinders of the vehicle, a flow control valve movably disposed within the valve chamber having projecting portions on one face of a flat portion thereof for providing a gap between the valve chamber wall and the valve in one end position of movement of the valve and a flow passage through the flat portion, a spring retainer secured within the inner end of the plug having a central opening for slidably receiving a central extension of the other face of the valve flat portion and a plurality of flow passages therethrough, and a compression spring between the other face of the valve portion and the spring retainer for normally maintaining the valve against the valve chamber wall with the projecting portions abutting thereagainst, whereby brake pedal depression and release alters the quantity of flui
