Abstract: The invention relates to a method for producing casting bodies in a levitation melting method in which a batch of an electrically conductive material is brought into the sphere of influence of at least one alternating electromagnetic field by means of a starting material having a plurality of pre-separated batches separated by regions of reduced cross-section so that the batch is kept in a state of levitation. The regions are designed in such a way that separation of the pre-separated batches takes place only during melting in an alternating electromagnetic field. The melt is then cast into casting moulds.

Abstract: Structures and methods for hindering molded part deformation during densification are discussed. Such devices and techniques can help alleviate stresses that tend to result in part deformation during firing, sintering, or other densification processes, and thus reduce the need for secondary straightening operations post-densification. In some instances, a support structure is utilized to orient a molded greenbody in a preferred direction to reduce deformation during firing (e.g., orienting a thin tail section is a plane parallel to the direction of gravity). The support structure can also be part of, or the entirety of, a thermal mass to help alleviate stresses that lead to part deformation. Though such structures and methods can be used for any molded piece, it can be particularly used to create a portion, or an entirety of, a medical device such as a jaw of an surgical instrument.

Abstract: A method for molding a molded substance to a substrate is provided. A substrate connected to a fixing portion by a connecting portion is prepared. The substrate is placed in a mold, wherein a portion of the fixing portion is protruding from the mold. The fixing portion is fixed by a fixing device outside the mold. Then, the molded substance covering the substrate is formed within the mold.

Abstract: An apparatus includes a scoring device for making transverse score lines on a roll of sheet material, a dimpler device or dimpler roller for making dimples adjacent the score lines at predetermined width locations, and a rollformer adapted to continuously form the sheet material into a tubular shape with channels. A welder is positioned in line with the rollformer and is adapted to weld the tubular shape into a permanent tube. A break off device positioned in line with the rollformer is adapted to break off sections of the tube at the score lines as the permanent tube exits the rollformer. The dimpler device is adapted to form an “in” dimple and an “out” dimple at locations coordinated with the score lines and with a width of the sheet material so that the “out” dimple forms a stop configured to slip into a channel formed in the sheet material by the rollformer but that abuts the “in” dimple which is formed at an end of the channel.

Abstract: Diffusion bonding techniques are extended to the simultaneous bonding of an array of multilevel piece parts. The problems of uneven expansion and contraction of different levels of different piece parts in the array are obviated by positioning each level of the array within a frame. The stack of frames is pinned in one corner. The opposite corner of the array has a slot at a 45° angle with respect to the x and y axes of the array. The slot engages a pin and allows the entire array to expand and contract along the slot in a manner to maintain the registration of features between respective levels of each piece part.

The components are connected to the hub at angularly spaced intervals by severable linkage portions.

Abstract: A pharmaceutical composition containing an extract from inflammatory tissue inoculated with vaccinia virus may be used to suppress the death of cells caused by endotoxin, and suppress excessive production of nitrogen monoxide induced by endotoxin. The extract may also be used to relieve hypotension induced by endotoxin. In sepsis and other serious bacterial infectious diseases, endotoxin (an intracellular toxin) is produced and a shock symptom is induced by its action. The extract, having an excellent inhibitory action toward endotoxin-induced toxicity, is quite useful for the treatment or the prevention of endotoxin-induced shock symptoms, sepsis and various symptoms accompanied thereby. In addition, the extract has an inhibitory action towards abnormal nitrogen monoxide production during the diseased state and, therefore, it is also useful as a therapeutic and preventive agent for diseases wherein an excessive nitrogen monoxide production occurs, such as acute hypotension.

According to the invention, a metallic surface susceptible to abrasion by rock-like material is protected by stud welding studs of abrasion resistant metallic material to the metallic surface in closely spaced relationship to cause the majority of the rock-like material to contact the abrasion resistant studs instead of the metallic surface. Typical of such metallic surfaces are a ground engaging tool, earth-working equipment, or chutes for conveying the rock-like material. The abrasion resistant metallic material comprising the stud can be formed of cast material of compacted metallic powder.

Abstract: This print hammer assembly method utilizes an elongated thin metal strip punched to form repetitive flag panels each having a flag region non-symmetrically linked to a surrounding frame, and a connector arm extending obliquely between the frame and flag. All assembly steps are performed while maintaining the panels connected in the strip. A flat coil, centered by a boss on the flag region, is sandwiched between and adhesively bonded to the strip and a second flag panel severed from another like strip. Spring wires are attached to the connector arms of both panels before sandwiching, and the coil leads are subsequently attached to the connector arms. Simultaneous soldering of the coil leads and spring wires to the connector arms is carried out from one side of the assembly strip, advantageously using solder paste and focused infrared heating. After discarding the excess frame portions, the hammers are embedded in a molding compound while still linked together in a strip.

Abstract: A scoring tool combination wherein the score anvil is provided with a pair of transversely spaced generally rounded material compressing ribs disposed on opposite sides of the scoring rib of the score tool. The material compressing ribs compress the material of the sheet being scored on opposite sides of the score so as to strengthen the sheet and thus permit deeper scoring and lesser score residuals without failure due to cracking. The material compressing ribs also control coating damage and exposed metal areas.

Abstract: A continuous tape is employed in the automatic assembly of semiconductor devices. The tape contains a sequential series of patterns, each one comprising a plurality of metal fingers. Each pattern includes fingers having an inward extension that terminates in a configuration that mates with the contact pattern of the semiconductor device. Desirably these fingers are thermocompression gang bonded to the semiconductor contact pads. This attaches the semiconductor device to the tape for further processing. In one assembly method the fingers have an outward extending portion that is designed for bonding to a secondary structure such as a lead frame destined to become part of the final housing. The fingers in the pattern are joined together by means of a ring located at or near the point at which they are bonded to the lead frame. After the lead frame bonds are achieved, preferably by thermocompression gang bonding, the ring is severed at locations between the fingers.

Transverse slots are formed in the strip-like sheet metal at given intervals in the longitudinal direction and a thin link portion and/or narrow width portion (sectional area in the transverse direction is small) is alternately formed at the top and bottom portions of the transverse slot. When an external force is applied to the metal carrier covered with rubber or plastics, the formed connecting links of the thin link portion and/or narrow width portion at top and bottom are broken, and the metal carrier becomes a continuous zigzag strip.
