摘要:
A method and an apparatus for fixing a part and a part support for mounting the part by use of adhesive via an intermediate member are disclosed. The adhesive is implemented by photocuring adhesive while the intermediate member is formed of a material transparent for light. The intermediate member is free from coloring and deformation when illuminated by light for curing the adhesive. The adhesive is prevented from dropping or turning round to other portions during assembly.

A battery is provided which has a high capacity and can improve battery characteristics, such as cycle characteristics. The battery includes a spirally wound electrode body, wherein a cathode and an anode are wound with a separator in between. The anode includes, for example, simple substances, alloys, compounds of metal elements or metalloid elements capable of forming an alloy with Li, the like and combinations thereof. An electrolytic solution wherein an electrolyte salt is dissolved in a solvent is impregnated in the separator. For the electrolyte salt, a light metallic salt having B—O bond or P—O bond, such as difluoro[oxalato-O,O′]lithium borate and tetra fluoro[oxalato-O,O′]lithium phosphate, can be used. By forming a stable coating, decomposition reaction of the solvent can be inhibited, and reaction between the anode and the solvent can be prevented.

Provided is a secondary battery in which high energy density can be obtained and charging/discharging cycle characteristic can be improved. A positive electrode (13) and a negative electrode (15) are stacked with a separator (16) interposed therebetween, and are enclosed inside an exterior can (11) to which an electrolyte is injected. The negative electrode (15) contains a negative electrode material capable of occluding/releasing lithium in an ionic state. Thereby, lithium metal precipitates in the negative electrode (15) in a state where the open circuit voltage is lower than the overcharge voltage. In other words, lithium is occluded in an ionic state in a negative electrode material capable of occluding/releasing lithium in the beginning of charging, and then lithium metal precipitates on the surface of the negative electrode material thereafter during charging. The amount of precipitation of lithium metal is preferable to be from 0.05 to 3.0 times, both inclusive, the ability of charging capacity of the negative electrode material capable of occluding/releasing lithium. Thereby, a high energy density and an excellent cycle characteristic can be obtained.

Provided is a battery capable of improving chemical stability of an electrolyte and battery characteristics such as discharge capacity, charge-discharge cycle characteristics and so on. The battery comprises a spirally wound electrode body (20) including a strip-shaped cathode (21) and a strip-shaped anode (22) spirally wound with a separator (23) in between. During charge, lithium metal is precipitated on the anode (22), so the capacity of the anode (22) includes a capacity component by insertion and extraction of lithium and a capacity component by precipitation and dissolution of the lithium metal, and is represented by the sum of them. The separator (23) is impregnated with an electrolyte solution formed through dissolving a lithium salt in a solvent. Vinyl ethylene carbonate, divinyl ethylene carbonate or the like is added to the electrolyte solution, thereby the chemical stability can be improved.

A rubber composition for a hose, which comprises a nitrile rubber (A) comprising 45-55 weight % of &agr;,&bgr;-ethylenically unsaturated nitrile monomer units and 55-45% by weight of conjugated diene monomer units, an epihalohydrin rubber (B), and a crosslinking agent (CA) for the nitrile rubber and/or a crosslinking agent (CB) for the epihalohydrin rubber; the amount of nitrile rubber (A) being 25-80 weight % based on the sum of nitrile rubber (A) and epihalohydrin rubber (B); and a hose having a layer comprised of a crosslinked product of the rubber composition. The hose has excellent resistance to fuel oil permeation and cold resistance, and therefore, it is especially suitable as fuel oil hoses of an automobile.
