Abstract: The present invention provides a metal terminal that can hold and fix a conductive wire thereto without excessive deformation. In the metal terminal of this invention, a predetermined relationship is set between a length in the lengthwise direction and a width in the widthwise direction of a conductive wire winding portion and a diameter of the conductive wire wound around the conductive wire winding portion to reduce force applied to the conductive wire when holding and fixing the conductive wire.

Abstract: It is provided a rewritable printing method and its printer in which a heat sensitive medium with a leuco type coating applied is used to rewrite the information repeatedly, printing can be performed in the same way as the conventional technique, and the medium easily as the transmission means of the information, thereby extremely contributing to the improvement of environmental issues relating to the use of paper.

Abstract: A card processing device capable of commonly attaining processing of a plurality of sorts of cards of the same specifications by means of a single card reader/writer. The card processing device includes a card including a print record layer and a magnetic record layer, as well as a card reader/writer including a thermal head for printing and a magnetic head for reading and writing. The magnetic record layer is provided with a card sort discrimination code record region, in which a card sort discrimination code for discriminating among a system card, a prepaid card, a stamp card and a point card is recorded. The card reader/writer has a prepaid card processing program, a stamp card processing program and a point card processing program stored therein, so that a program to be executed may be automatically selected depending on the card sort discrimination code read, resulting in card processing being attained.

Abstract: A miniature D.C. motor for a toy allows the arrangement of a brush base in a housing of the motor to be readily and positively positioned to improve the manufacturing efficiency of the motor and to ensure the actuation of the motor without trouble for a long period of time.The motor includes a housing, a brush base which holds brushes therein and which detachably fits in the housing, and a detachable connection member for permitting a connection between the housing and the brush base. A motor further includes a commutator having an outer end formed into a truncated conical shape, wherein the brushes each are provided with a contact section having a convexly curved surface, to allow the outer end of the commutator to be pressedly interposed between the convexly curved surfaces of the brushes.
