Provided is a nonaqueous electrolyte secondary batterywhich, in cases where separatorseach having a heat-resistant layeron only one face thereof are used, has an excellent thermal stability and thus a higher safety and reliability when the batteryreaches a high temperature. Such a nonaqueous electrolyte secondary batteryincludes a positive electrodein which a positive electrode active material layeris provided on both faces of a positive electrode current collector, a negative electrodein which a negative electrode active material layeris provided on both faces of a negative electrode current collector, at least two separatorseach having a heat-resistant layeron one face of a base material, and an electrolyte. The nonaqueous electrolyte secondary battery has an electrode assemblyin which the positive electrodeand the negative electrodeare stacked on top of one another with the separatorsinterposed therebetween. The at least two separatorsare disposed in such a way that, for each separator, the heat-resistant layeris positioned on the same side with respect to the base materialin the stacking direction.

In a liquid-sealed antivibration devicewhich includes: a main liquid chamberA where a vibration-isolating baseforms a portion of a chamber wall thereof; a subsidiary liquid chamberB where a diaphragmforms a portion of a chamber wall thereof; a partition elementby which the main liquid chamberA and the subsidiary liquid chamberA are partitioned from each other; and an orifice flow passagewhich allows the main liquid chamberA and the subsidiary liquid chamberB to be communicated with each other, an elastic membraneis formed on the partition element, and the elastic membraneis formed of rubber composition containing butyl rubber or halogenated butyl rubber. Due to such a constitution, an abnormal sound generated by collision of the elastic membraneis reduced.

A joint boot which is made of resin comprising a small-diameter cylinder part, a large-diameter cylinder part and a bellows part interlinking both is molded by injection blow molding. While forming the bellows part by blow molding, the exterior boundary between an injection molding section and a blow molding section is set in a cutout portion formed in a shoulder portion of the recess for fixation.

Method of producing joint boot made of resin

There is provided a flexible resin boot of which the noise-preventing effect lasts long and which ensures improved sealability and durability. The boot is formed from a base resin of a thermoplastic elastomer resin, and has a large port and a small port that are connected with each other via a bellows therebetween. For this, mineral oil or vegetable oil is added to the thermoplastic elastomer resin. Preferably, the thermoplastic elastomer resin is a thermoplastic polyester elastomer, and the mineral oil is process oil having an aromatic content of at most%. The boot is used for covering the constant velocity joint in an automobile.

A multilayered hydrogen absorbing body is provided which is formed by laminating at least two types of hydrogen absorbing materials. The degrees of strains cause due to absorption/desorption of hydrogen are different between the hydrogen absorbing materials adjacent to each other.
