Abstract: “”-shaped slits and linking portions are previously provided so as to surround a semiconductor chip-mounting region in a TAB tape. A semiconductor chip is applied onto the semiconductor chip-mounting region. The semiconductor chip in its electrode pad is connected by bonding to the TAB tape in its inner lead. The bonded connection is subjected to plastic molding. Solder balls are provided on the backside of the TAB tape in its portion corresponding to the semiconductor chip-mounting portion. Thereafter, the package portion is cut off at the cutting position in the linking portion of the slits. By virtue of the above constitution, highly reliable BGA type semiconductor devices can be produced while reducing the thickness and reducing the size.

Abstract: A print wire driving device for a wire dot printer includes a plate like member having slots therein. The slots are arranged opposite the cores of a magnetic core block. The cores are arranged in a circle and project from the core block. The slots extend radially from the center of the plate like member. A magnetic driving member is received in each slot so that it pivots therein when acted upon by the magnetic field of a respective magnetic core. A print wire is coupled to each magnetic driving member. Each print wire is guided by a wire guide having a wire nose which receives at its end a wire guide member from which the ends of the print wires extend to print. The wire guide includes structure for properly aligning two stacks of magnetic actuators.

Abstract: The technical field of the present invention relates to an apparatus for automatically threading a warp through the eye of a heddle. In a conventional automatic warp threading apparatus, a drawing-in needle equipped with a hook is delivered out through the eye and is pulled back after hooking the warp so as to thread the warp through the eye. For this reason, the eye is likely to be damaged and a defect is likely to occur during weaving. The automatic warp threading apparatus of the present invention warp threading apparatus of the present invention clamps the warp (Y) with finger members (18, 18') disposed on a thread feeder (5) and a jet nozzle (20) fitted to the finger members (18, 18') ejects a gas so as to thread the clamped warp (Y) through the eye. Accordingly, the eye is not damaged and weaving can be made advantageously.

Abstract: A wire dot printer using a plurality of print wires to print on a printing medium. The printer includes a print head unit, a guide member defining a wire nose mounted on one end of the print head unit, and a wire guide member mounted proximate one end of the guide member and including a plurality of openings for guiding the print wires. A supporting member is mounted on the guide member on the one end thereof and has a first surface for coupling the supporting member to a carriage. The supporting member has an end surface having an opening therein corresponding in shape to that of the end of the guide member supporting the wire guide member. The wire guide member is positioned and supported in the opening in the supporting member. The guide member also includes a plurality of spaced wire guide plates which include a plurality of holes aligned therein through which the print wires extend for guiding the print wires.

Abstract: A wire dot printer includes a print head which is more reliable and better controls a gap between a magnetic pole and a print lever. The print head includes a core block and nose block. The core block includes a projection for regulating oscillations of a print lever at its inner central portion. A print lever drive coil for each print lever is formed on the core block about the projection. The nose block includes a disk member which is mounted opposed to the core block. A print lever is movably supported between the nose block and core block.

Abstract: A wire guide member for use in a wire type dot printer for guiding print wires and having a guide member with grooves. The wire guide member includes a first plate formed of synthetic resin, a second plate being formed of a wear resistant material and a third plate also formed of a synthetic resin. Through-holes in the plates are aligned to receive the print wires. Also disclosed is an assembly for supporting a member in a wire type dot printer.
