摘要:
The object of the present invention is to provide an electrode for secondary battery according to which the electrode density can be increased and furthermore the electric characteristics can be improved. In the present invention, the sheet material for electrode to be laminated on the surface of a current collector is prepared by mixing and kneading a powdered positive electrode active material or negative electrode active material and a finely powdered conductive material as main components to which a fluorine-containing polymer resin is added, screening the resulting mixture by a sieve to obtain particles of the mixture, adding a liquid lubricant to the particles, preforming the particles to make a sheet-like formed body, and stretching the sheet-like formed body in mono-axial or multi-axial direction.

Disclosed is a sliding member having a bearing alloy layer, an intermediate layer of Ni or a Ni alloy formed on the bearing alloy layer, and an overlay layer of a Sn alloy containing Cu formed on the intermediate layer. There exist Sn—Cu compounds in the overlay layer, which protrudently extend from the intermediate layer. The hard Sn—Cu compounds contribute to the overlay layer in improving fatigue resistance property. A soft Sn matrix being rich in an outer surface region of the overlay layer is responsible for keeping good conformability to have excellent anti-seizure property.

A bearing with an oil film thickness measuring device in which sensor portions at distal ends of four common optical fibers are connected to sensor mounting portions formed at four positions in an axial direction of a bearing body. A lubricating oil containing a fluorescent agent is supplied to a sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to an oil film on a sliding surface through each of sensor portions. Fluorescence generated by the fluorescent agent in the oil film, passing through a return-route optical fiber, is introduced into a photomultiplier tube, and is detected. Since the fluorescence intensity detected by the photomultiplier tube is proportional to the thickness of oil film, the absolute value of oil film thickness can be measured. In this case, the oil film thickness can be measured at four positions.

The reformer 100 includes: an evaporating unit 102 that has a source fuel inlet 114 through which hydrocarbon-containing source fuel 202 is introduced, and is capable of evaporating a source fuel 202 introduced through the source fuel inlet 114; a catalyst containing unit 104 that is provided in the evaporating unit 102 and stores a reforming catalyst 108, which is capable of inducing a reaction for reforming the source fuel 202 into a reformed fuel having higher hydrogen amount; and a hydrogen outlet 118 that is provided on the catalyst containing unit 104 so as to communicate with the catalyst containing unit 104.
摘要:
A multilayer aluminum-base alloy bearing formed by bonding a bearing alloy layer made of an aluminum-base alloy to a steel back metal through an intermediate layer made of an aluminum-base alloy, the intermediate layer being composed of two layers, that is, a lower layer and an upper layer, the lower layer in contact with the steel back metal being lower in hardness than the upper layer. Since the lower layer is soft, it is excellent in bonding property for the back metal, and since the upper layer is hard, it withstands a load exerted on the bearing alloy layer.
摘要:
A Bi base material of which a Miller index (202) face has the index of orientation of not less than 30% and in which the (202) face has the index of orientation assuming a maximum value as compared with those of other faces forms a minute structure and has a surface which is not a mirror finished surface but a fine, irregular surface on which minute and uniform projections in the form of a triangular pyramid or a quadrangular pyramid congregate. Therefore, the surface easily retains oil thereon to be improved thereby in oil wettability, as a result of which an improvement in anti-seizure is achieved.

A polarizing electrode for an electric double layer capacitor has good moldability and can achieving higher density of electrode and higher capacity, and an electric double layer capacitor employs the same. The electric double layer capacitor is made of an activated carbon obtained by activating a hard-to-graphitize material (for example, phenol resin) with water vapor, and the activated carbon has a median particle size within a range from 4 μm to 8 μm in the particle size distribution and at least a peak observed on the side of smaller particle size than the median particle size in the particle size distribution.

In a cylindrical sliding bearing, a radial rigidity of an inner circumferential surface of a sliding layer against a radial compression force applied to the inner circumferential surface by a shaft varies in a circumferential direction so that the inner circumferential surface includes a relatively-high radial rigidity bearing area and a relatively-low radial rigidity bearing area.

A plain bearing is provided which has an Sn-and-Si-rich layer formed of an Al alloy containing Sn and Si, and a base material which does not contain Sn. The Sn-and-Si-rich layer have the sliding surface having an area ratio of Sn phase grains in a range of 6 to 40% and that of Si phase grains in a range of 5 to 25%.

A plain bearing comprising a housing and two plain bearing halves forming a cylindrical shape in combination and fixed in the housing. Each of the plain bearing halves has crush relieves formed at both ends of an inner circumferential surface thereof in a circumferential direction, an oil groove formed on the inner circumferential surface thereof and extending in the circumferential direction, a central crown portion at substantially central position in the circumferential direction and in communication with the oil groove, and inflow preventing portions formed between the crush relieves and the oil groove.
