Abstract: A multilayer non-irradiated film comprising a core layer, a respective further layer laminated to each side of the core layer, and an additive capable of migrating within the film, is prepared by:
     (i) blending an additive, such as a fungicide, encapsulated in a first thermoplastic resin, with a second thermoplastic resin which has a lower melting point than the first resin so that during extrusion of the blend the second resin melts and surrounds the encapsulated additive before the first resin melts; and   (ii) coextruding the resulting blend to provide a layer, preferably the core layer, of the film and respective thermoplastics resins to provide the other layers of the film.   
     Preferably a five layer film is formed in which a respective intermediate layer is provided between the core layer and each outer layer. A heat-shrinkable film may be formed by subsequently orienting the film. The film can be used to package articles such as fruit and vegetables to protect them from fungal infection.

Abstract: A method of cleaning articles by removing surface particulate matter from the articles in which the articles are immersed in a bath of liquid cryogen 14, chemically non-reactive with the articles to be cleaned. Prior to immersion it is necessary to insure that the articles 12 have a sufficiently high temperature above that of the liquid cryogen 14 and during immersion it is also necessary to insure that the articles are immersed at a sufficient rate to insure that the liquid cryogen undergoes film boiling before undergoing nucleate boiling at the surfaces of the articles. The articles are left immersed so that nucleate boiling of the liquid cryogen occurs at the surfaces of the articles. During the nucleate boiling, the surface particulate matter is carried from the articles and into the liquid cryogen bath. After the articles have reached thermal equilibrium with the liquid cryogen, the articles are removed from the bath. The method can be carried out in an atmospheric environment and at room temperature.

Abstract: For protecting an electrical load (4), which is controlled in accordance with the face-gating principle, where faults occur, a drive circuit (2) is provided for a semiconductor switching element (3), which drive circuit switches off as a function of fault criteria for the switching-on of the semiconductor switching element (3). The switching-off is initiated in the event of a fault accumulation by means of an assessment device (11) which is preferably designed digitally and compares fault signals, which are derived from monitoring signals for the semiconductor switching element (3), with reference signals. In the event of not switching on, a drive repetition signal attempts to activate the semiconductor switching element (3) and, when an inductive load (4) is on no-load, the driving of the semiconductor switching element (3) is delayed until the zero-crossover of the load current - preferably not continuously.   <IMAGE>

Abstract: Data to be processed is stored within data files 20. Associated with each data file 20 is a header file 18. The header files 18 store data specifying a wide range of attributes of the data within the data files 20. A user selects a particular signal processing function 14 that he desires to use and this then accesses one or more selected data files 20 and associated header files 18. The selected signal processing tool 14 only needs a set of the attributes stored within the header files 18. The signal processing tool 14 reads those attributes it requires and then manipulates the data within the data file 20. The provision of this structure allows a wide range of signal processing function tools to be integrated into a single system which may also be simply expanded.

Abstract: A surgical cutting instrument for coring, debulking, and removing a large, tough tissue mass such as a fibroid tumor through a trocar access sheath during a minimally invasive surgical procedure. The instrument includes an outer sheath having a distal cutting end for coring the tissue mass and an inner elongated member having a distal, tissue affixation end such as a helical coil for inserting into and stabilizing the tissue mass during the surgical coring procedure. The cutting instrument further includes an instrument engagement assembly when in an engaged position for urging the outer sheath toward the distal end of the inner elongated member. As a result, tissue affixed to the distal end of the inner elongated member is cored as the outer sheath is urged toward the distal end of the inner member and engages the affixed tissue. The instrument engagement assembly includes sheath and member engagement subassemblies. The sheath engagement subassembly is positioned about the proximal end of the outer sheath and includes a hub with a pivotedly interconnected side arm. The member engagement subassembly positioned along the intermediate portion of the inner member includes multiple start helical threads. The side arm has projections extending laterally therefrom for extension into the passage of the hub and engaging the multiple start helical threads of the inner member.

Abstract: An intraoperative ultrasonic transducer probe is described comprising a handle section (20) and a transducer section (22) which resemble a tiny leg and foot. The two sections are obtusely angled relative to each other so that the physician may continue to clearly view the surgical site while holding and manipulating the probe. The extension of the transducer section away from its point of attachment to the handle section results in the toe (18) of the foot being insertable under unincised tissue, enabling the surgeon to ultrasonically examine organs and tissue peripheral to the surgical site and to follow a vessel even beyond the incision. The transducer section is completely encapsulated in a rubberlike material (44) which electrically insulates the transducer from the patient, enables the probe to be easily sterilized, and further provides an inherent standoff between the transducer and the contact surface of the probe. Thus, the transducer can be focused immediately at the skin line of the organ or vessel which is in contact with the probe. The probe can be easily assembled by providing termination assemblies for attaching coaxial cable conductors to the printed circuit board assembly of the probe.

Abstract: Apparatus for attaching together i) a surgical needle (100) having a generally cylindrical end portion (120) defining an elongate aperture (102) having a generally circular cross-section and ii) a suture (200) having a generally elongate end portion of generally circular cross-section corresponding in dimension to the elongate aperture (102) of the needle (100). The apparatus includes a pair of dies (20), each having a die face (24) with an inner die surface portion (28). The inner die surface portion (28) includes at least one generally planar crimping surface (30) having an arcuate recess (32) formed therein which extends along at least a portion of the planar crimping surface (30). The arcuate recess (32) defines a material relief zone such that when the end portion of the suture (200) is positioned within the aperture (102) of the needle (100) and the dies (20) are positioned about the generally cylindrical end portion (120) of the needle (100) with the crimping surfaces (30) generally facing the outer surface thereof, the application of an inward crimping force to the dies (20) causes the dies (20) to impact the needle (100) and produce inward crimping forces on opposed sides of the needle end portion (120) to attach the needle (100) to the suture (200). The relief zones defined by the arcuate recesses (32) receive and collect deformed material from the needle (100). According to the invention, the symmetry of the needle (100) is maintained and the attachment is predictable and superior to those of the prior art. A surgical needle-suture combination having a controlled suture release is also disclosed as well as a method for forming such attachment is also disclosed.

Abstract: In case where an engine rotational detection signal from an ignition pulse generator is not appropriately detected even if an amount of induction air and a fuel injection amount are larger than predetermined values, an engine rotational signal failure is decided, and an automatic transmission is controlled in a state before the decision. Thus, the automatic transmission control can be executed based on the engine rotational speed. In case where a failure of the cruise control set signal line is detected, the automatic transmission control based on the cruise control is prohibited. The normal state is recovered when an off signal of the cruise control set is detected in the above-described conditions. Accordingly, since a failure of the cruise control set signal line is reliably detected, the automatic transmission control is appropriately executed by using the cruise control signal. Thus, the automatic transmission control can be executed based on a cruise control signal.

Abstract: A semiconductor integrated circuit device comprises a boost potential generation circuit (24), word line drive system circuit (25), refresh cycle select circuit (21), word line system boost potential control circuit (22) and boost potential generation system control circuit (23). The boost potential generation circuit (24) steadily generates a higher boost potential (φ3) than an externally applied voltage. The word line drive system circuit (25) delivers the boost potential (φ3), as a power supply, from the boost potential generation circuit (24) so as to drive the corresponding word line. The word line system boost potential control circuit (22) sets at a substantially constant level a boost potential output from the boost potential generation circuit (24). The boost potential generation system control circuit (23) receives a designation signal (φ4) from the refresh cycle select circuit (21) so as to designate a refresh cycle and supplies a control signal (φ2A-1 to φ2A-n), which is generated based on the designation signal (φ4), to the boost potential generation circuit (24), whereby, when more word lines are driven at a time by the word line system drive circuit (25), a current supply capability of the boost potential generation circuit (24) is increased and, when less word lines are driven at a time, the current supply capability of the boost potential generation circuit (24) is decreased.
