Abstract: An electromagnetic mark device for any type of magnetism encoder applies the electric current magnetic field as the electromagnetic mark thereof. The electromagnetic mark device comprises an insulated base plate and a thin lead wire. The thin lead wire is fixed to the insulated base plate. It is characterized in that the thin lead wire is laid out on the base plate as a circuit in a way of providing a continuously twisted and turned shape with a constant pitch.

Abstract: A method for controlling plating with two independent power sources, wherein the high voltage power source is used for controlling the electrical swimming speed of the metal positive ions while the other is low-voltage power source for being used to control rate of plating rate. Positively charged metal ions of the strong electric field in the plating solution can reach to the negatively charged and unevenly distributed surface of the extraction negative pole more quickly, which is in turn connected to the negative of the low voltage power source. The ions aggregate at the recess of the extraction negative pole surface and waiting incoming electrons so as to perform electric extraction and produce uniform plating. The present invention also provides the apparatus for carrying out the mentioned method and therefore achieves better plating quality.

Abstract: A cobalt-chromium (Co-Cr) magnetic film electrodeposited on the surface of an aluminum alloy. A process for making an aluminum alloy electrodeposited a cobalt-chromium (Co-Cr) magnetic film comprises the steps of chemically polishing an aluminum alloy substrate, pretreating either with phosphate or with zincate and electrodepositing in a plating bath containing cobalt and chromium ions to prepare the cobalt-chromium thin film on the aluminum alloy. Chromium content in the film can be designed by adjusting the parameters of pretreatment and electroplating. The produced cobalt-chromium film can flexibly adjust the magnetic characteristics (e.g. coercive force (Hc) and ramanence magnetization (Mr)) and is suitable for use in a magnetic recorder. The chemical composition, adhesion, microhardness, magnetic properties of the deposits indicate that the Co-Cr films produced are satisfactory for magnetic recording service.

Abstract: A card reader includes a base having formed thereon two spaced walls defining therebetween a card slot through which a card is movable. Both of the walls have two openings formed thereon to be opposite to each other. A write transducer and a read transducer are respectively suspended by a first biasing member to be located within the openings of one of the walls. A dummy transducer is also suspended by a first biasing member within one of the openings of the other wall. The dummy and read transducers are opposite to each other so as to provide a force and position to the card moved through therebetween. A roller co-axially mounted to and rotatable in unison with an encoder is rotatably supported by a second biasing member within the other opening of the other wall to be opposite to the write transducer to provide a force and position to the card moved through therebetween.
