    摘要： The present invention provides a process for producing a superconducting transistor on a surface of an insulating substrate. A pre-superconducting thin film contains a material that can be changed into a superconductor during subsequent processing but which is initially a non-superconductor. A thin film containing the material required by the pre-superconducting thin film is deposited in a preferred pattern on the pre-superconducting thin film. The assembly thus formed is heat treated to permit the material from the thin film to enter the pre-superconducting thin film, thereby forming superconducting regions in the pre-superconducting thin film in the preferred pattern. The superconducting regions form electrodes of the transistor.

    摘要： A twin head for use in an electronic still camera includes a shield plate, first and second head chips bonded on opposite sides of the shield plate, and first and second reinforcing core members further bonded on first and second head chips, respectively. Each of the first and second head chip members has an elongated face that faces a recording medium and a magnetic gap defined at an intermediate portion of the elongated face. The length Wh of the elongated face is between 0.3 millimeter and 1 millimeter. Each of the first and second reinforcing core members has a coil wound thereon. The first and second head chip members, the shield plate, and the first and second reinforcing core members are bonded together such that the elongated faces of the first and second head chip members are in flush with each other and that the magnetic gaps of the first and second head chip members are aligned to each other.

    摘要： A magnetic transducer includes sendust center core having an opening and a head gap extending from the opening to one side of the center core, and a pair of reinforcing cores. Each of the reinforcing cores includes a ferrite plate and a glass member mounted on one side of the ferrite plate. The center core is sandwiched between the two reinforcing cores such that the glass members are located on opposite sides, respectively, of the center core where the head gap is formed, and that one side of the center core is in flush with, or projects from, respective side faces of the glass member. The glass member is formed by a material having an abrasiveness resistivity which is smaller than that of said center core.
