Abstract: A charging apparatus includes a DC-DC converter for stepping down a charging input voltage, and a charging current controller having two input terminals and one output terminal. The input terminals receive a voltage based on a charging current drawn from a voltage stepped down by the DC-DC converter. The voltage at the output terminal serves as a control voltage for controlling the charging current drawn from the stepped-down voltage.

Abstract: In a method of producing a transfer film for providing pictures onto a molded product simultaneously with molding of the present invention, a resin which is dispersed in a dispersing medium to form a water-dispersed emulsion is coated on a substrate film made of a water-insoluble thermoplastic resin. Then the substrate film is dried until the coat solidifies to form a release layer. Further, a transfer layer which includes paint or ink diluted with an organic solvent for forming a desirable picture is formed on the release layer. Thereafter, the solvent is evaporated until the transfer layer turns to a solid film. Thus produced transfer film is used in the provision of pictures onto a molded product simultaneously with molding while insuring that the substrate film of the transfer film can be smoothly peeled from the picture or design layer after it is transferred to the shaped part without impairing the molding efficiency.
Abstract: An electronic engraving system is provided wherein an object, e.g., a person, for a picture to be engraved on a card is picked up by a television camera and converted into corresponding electric signals; the electric signals are stored first and then read out at a lower scanning speed that suits a mechanical scanning system through scanning conversion means, and the picture of the object is engraved on the material in accordance with the read out signals, whereby the picture corresponding to the object can be easily engraved on the material, e.g., a plastic card without using any photographic original picture of the object.
