The light reflecting plate has a substrate made of metal plate, a binder layer made of organic resin or an inorganic material, which is formed on the substrate, a reflective layer formed of a plated layer of silver or silver alloy containing silver as a main component, which is formed on the binder layer, and a protective layer formed on the reflective layer.

Light reflecting plate, method of manufacturing the same and light reflecting device

A battery container having an inner surface provided with a nickel-phosphorous alloy layer, optionally provided with a nickel-cobalt alloy layer as the lower layer thereof. The outer surface of the battery container is preferably provided with a nickel-cobalt alloy layer. Batteries made using the battery containers of the present invention have excellent performance.

Surface-treated steel sheet for battery container, a battery container, and a battery using same

The objective of the present invention is to produce a surface treated steel sheet for a battery container of which electric contact to the positive electrode active material is improved, a method of surface treatment for a battery container, a battery container and a battery, wherein the surface treated steel sheet has a graphite dispersed nickel plating layer or a graphite dispersed nickel-alloy plating layer formed on the one side to be the inner surface of a battery container, in which nickel-cobalt alloy, nickel-cobalt-iron alloy, nickel-manganese alloy, nickel-phosphorus alloy, nickel-bismuth alloy or the like is preferable as an alloy plating layer, the battery container is manufactured from these surface treated steel sheets by DI forming or DTR forming, and the battery uses this battery container.

Surface-treated steel sheet for battery case, method of production thereof, battery case formed by the steel sheet and battery using the case

A plated steel sheet and a connection terminal material using the plated steel sheet have low contact resistance and excellent corrosion resistance. The coated film, which has excellent adhesion, is formed by coating a stainless steel base sheet which is coated with a nickel-tin alloy with a solution/suspension of carbon black or graphite, carboxymethyl cellulose, and a water-borne organic resin which is acrylic resin, polyester resin, urethane resin, or phenol resin.

Surface-treated steel sheet having lowered contact resistance and connecting terminal members made by using the same

Surface-treated steel plate having low contact resistance and connection terminal member made of the steel plate

A method for producing a metal substrate for a lithographic plate is provided herein by treating the substrate having the thickness in the range of 50 to 400 .mu.m. The said substrate is electrochemically, chemically or mechanically treated in order to provide an average surface roughness in the range of 0.1 to 3 .mu.m, followed by a surface treatment such as plating or chemical treatment, and then followed by a conventional hydrophilic treatment.
