Abstract: Microporous poly (tetrafluoroethylene-co-perfluoro (alkyl vinyl ether) (PFA) or poly(tetrafluoroethylene-co- hexafluoropropylene) (FEP) membrane or hollow fibers are formed from a melt blend of 10 to 35 weight percent of PFA or FEP and a chlorotrifluoroethylene oligomer solvent. The melt blend is shaped and cooled to effect phase separation of the PFA or FEP from the blend. The solvent is removed from the PFA or FEP by extraction and the porous PFA or FEP is dried under restraint to prevent shrinkage.

Abstract: The invention described herein is drawn to a hollow cylindrical filter for use with a suction canister including a first portion having an open end and a first wall thickness, a second portion having a closed end and second wall thickness less than said first wall thickness, and an elongate central chamber having a substantially uniform diameter along its length. The filter is composed of a composite material including a porous plastic material and material adapted to increase the viscosity of a liquid coming into contact therewith. The filter is constructed to accommodate the changes associated with air flow velocity and shear force across the filter material as the fluid level in the canister rises, and automatically shuts off the vacuum to the interior environment of the suction canister. The invention also includes a filter system including such a filter in combination with a filter shield which accommodates the filter within and attaches to, or is alternatively integrated with, the underside of a suction canister lid.

Abstract: There are provided an apparatus and method for friction welding structural members. The apparatus includes a connected shank and probe. The probe defines an absorption surface and a cavity extending thereto. The absorption surface is configured to receive electromagnetic radiation from an electromagnetic radiation source such as a light source or RF generator. The radiation heats the probe, supplementing the heat generated by friction between the probe and the structural members, and thereby increasing the speed at which the probe can be used to frictionally weld the structural materials.

Abstract: In a reinforcing steel that has indentations (4) rolled into a steel rod of approximately circular cross section, the indentations are formed as the reinforcing steel is unwound through circular arcs of different radii set axially symmetrical relative to the indentation. The indentations are rolled into the surface of the rod at a constant depth and have steep flanks. This ensures sufficient bonding despite a lower deformation effort, providing for better ductility parameters. Furthermore, the coiled reinforcing steel has better directivity and improved suitability for welding in the manufacture of welded wire mesh. A process for manufacturing such a reinforcing steel comprises at least two deformation steps.

Abstract: In order to test an integrated circuit having a sequential logic, the register stages contained therein are switched in series as a shift register. In this case, running time problems can arise which can be avoided by a two-phase operation of the register stages, as is the case, for example, with the known LSSD technology. For a high processing speed, however, edge-triggered register stages are more favourable. According to the invention, register stages are therefore proposed which can easily be switched over between a two-phase operation during testing and edge triggering in normal operation. In this case, only one additional clock line is required. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To provide excellent responsiveness even when the operating mode changes because of rapid increase of the requested output, in a hybrid vehicle traveling in a plurality of the operating modes in which the working conditions of an engine and an electric motor serving as the power source are different. SOLUTION: When the increase factor dθAC/dt of the accelerator operating amount θAC is a decision value θ or more (at SA1 the result is YES), at least the engine is operated as a power source. When the engine is in a stop condition and the operating mode just before is a motor operating mode (at SA2 the result is YES), the motor torque is made rapidly rise up (SA4), the time lag to the engine start is compensated. When the operating mode just before is an engine operating mode (at SA11 the result is YES) or in an engine + motor operating mode (at SA13 the result is YES), acceleration requirement is satisfied mainly by the engine, so as to suppress the burden increase of the motor.
