摘要： Aluminum or aluminum alloy is first anodized to form an oxide film thereon. The anodized basis metal is electrolyzed by use of alternating current in an electrolytic solution which is prepared by adding formaldehyde, usually as formalin, and a thiosulfate to an acid solution of stannous sulfate. The acid solution of stannous sulfate can be prepared by dissolving stannous sulfate in an aqueous solution of sulfuric acid, sulfamic acid, tartaric acid or the like.

摘要： Aluminum or aluminum alloy is first anodized to form an oxide film thereon. Before being colored electrolytically in an electrolytic solution, the anodized basis metal is made anodic in this solution, and direct current is passed therethrough. The basis metal is then electrolyzed in the same solution by use of alternating current for actual coloring operation. The electrolytic solution in use contains at least two metallic salts, together with or without a strongly reducing compound.

摘要： An encoder includes a rotary member having a predetermined electrode pattern and a fixed member having multiple channel contacts which are opposed to the electrode. The rotary member has stable reference phases where at most one pair of the contacts is ON (in electrical contact) and at least another pair is OFF (not in electrical contact), i.e. both pairs may be OFF. When the rotary member is rotated clockwise or counter-clockwise from one reference phase, both pairs of contacts are temporarily on before reaching the adjacent reference phase. The pairs of contacts that are ON or OFF at the adjacent reference phase differ dependent on the direction of rotation. A counter is incremented or decremented according to the direction of rotation.

摘要： The invention provides a novel and improved method according to which the surface of a shaped article of aluminum or an aluminum-based alloy is provided with decorative streak patterns electrolytically engraved in the surface which can be subsequently colored to increase the decorative effect with uniform distribution over whole surface of the aluminum article. The method comprises first subjecting the anodically oxidized aluminum article to an anodic direct current electrolysis in an electrolytic solution containing a specified electrolyte and then carrying out a cathodic direct current electrolysis with the aluminum article and the counterelectrode kept as before in the same electrolytic solution as used in the first anodic direct current electrolysis with reversed polarity to give uniformly distributed streak patterns on the surface of the aluminum article. The surface of the aluminum article thus provided with the streak patterns is subsequently anodized to enhance the corrosion resistance and then subjected to a coloring treatment.

摘要： Disclosed is an encoder including a rotary member and a fixed member. The fixed member is provided with an electrode having A-channel, B-channel and C-channel patterns, the rotary member is provided with contacts which are to be opposed to the electrode. A-C state switches from OFF to ON at each rotation of the rotary member for one click angle from a stable click position in both CW and CCW direction. During CW rotation for one click angle, B-C state remains unchanged from OFF; during CCW rotation for one click angle, B-C state switches twice between ON and OFF.
