The resin member is made of a resin material including a thermoplastic main resin having a first glass transition temperature equal to or higher than 70° C., a thermoplastic elastomer, and a filler. The elastomer has a second glass transition temperature that is equal to or higher than ?10° C. and equal to or lower than 20° C. and a third glass transition temperature equal to or lower than ?40° C.

Abstract: A power storage device includes a current collecting terminal, a case member having a terminal insertion hole, and an insulating resin member connecting the current collecting terminal with a hole periphery and a hole surrounding portion of the terminal insertion hole. The current collecting terminal and the case member have seal portions that ensure airtightness in a case, at connecting portions connecting with the insulating resin member, and each of the seal portions is a roughened surface. The insulating resin member has a thermoplastic resin material including high molecular weight particles with a molecular weight of 10,000 or more and low molecular weight particles with a molecular weight of 500 to 5,000, and the low molecular weight particles are included 5 to 15% by weight in the thermoplastic resin material and are unevenly distributed closer to the roughened surface.

Abstract: This cylindrical cutter for skiving comprises a plurality of cutting edge parts in the circumferential direction by having tooth grooves be formed between circumferentially adjoining cutting edge parts with the tooth grooves being formed into a helical shape twisting in the axial direction. Cutting edge grooves are each formed in the cutting edge parts so as to divide the cutting edge parts into multiple sections in the length direction of the tooth grooves.

Abstract: The invention provides a heat recovery method for use in sulfuric acid production plants by which the heat generated in the step of drying SO2 gas or the step of drying air, and the step of absorbing sulfur trioxide in the plant is effectively utilized for heating the water to be supplied to a boiler although the heat is conventionally discarded because of the difficulties encountered in using the heat effectively. The boiler water to be supplied is heated by utilizing the heat generated by drying and/or absorption in a drying tower of the plant for drying sulfur burning air or the sulfur dioxide and/or in an absorption tower of the plant for causing circulating concentrated sulfuric acid to absorb sulfur trioxide produced by the conversion of the sulfur dioxide.

Abstract: Gear cutting is to be effected in high efficiency and at low cost. To this end, using a hob 16 coated with at least one layer of a film of a composition comprising:(Ti.sub.(1-x) Al.sub.x)(N.sub.y C.sub.(1-y))0.2.ltoreq.x.ltoreq.0.850.25.ltoreq.y.ltoreq.1.0,dry cutting is performed at a cutting speed in the range of 80 to 400 m/min without using a cutting oil. Teeth can be generated at a greatly improved cutting speed without using any expensive tool such as a tool made of cemented carbide.

Abstract: A horizontal hobbing machine comprises a bed, a cutting section provided on the bed and including at least a horizontal rotary shaft and a hob. The cutting section generates a tooth form on a work piece supported around the rotary shaft by means of the hob. A conveyor is provided in a lower part of the cutting section below the bed to remove chips of the work piece resulting from the cutting process.

Abstract: An apparatus for detecting an angular rate of a moving body has first and second sensors each of which has a detection direction, the first and second acceleration sensors are mounted at fixed locations on a moving body so that the first and second acceleration sensors have substantially the same detection direction on a plane and a fixed distance therebetween in the detection direction, and the angular rate (.omega.) of the moving body is detected according to the following equation: ##EQU1## wherein .DELTA.G is an acceleration difference and R is the distance between the first and second acceleration sensors in the detection direction.

Abstract: An apparatus induces vibrations in a generator for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. The load torque of a generator fixed to the engine is changed to generate an angle moment on the body of the generator to cancel engine vibrations due to rough idling and suppress body vibrations due to the rough idling. Irregular combustion of the engine is detected from a change in the engine speed, and a voltage higher than the output voltage of the generator is than applied across the field winding to increase the field winding current and hence the load torque on the generator, which induces vibrations on the generator body. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled.

Abstract: In an engine control system of the type in which engine control data is calculated for each of a plurality of cylinders, rotation angular speeds of the crank shaft are sequentially detected as individual pistons of the plurality of cylinders take an identical, predetermined stroke position, for example, top speed position and rotation speed data and control data are calculated on the basis of the detected rotation angular speed.
