Abstract: A drawing machine for drawing a workpiece (41) comprises first and second drawing dies (42, 43), first and second push rods (45, 46, 47, 48) and first and second junction rods (53, 54). When the first push rods (45, 46) are downwardly moved, the first junction rod (53) is pressed and moved by the first push rod (45) to press the first drawing die (42). Consequently, the first drawing die (42) forms a first-stage drawn part in the workpiece (41). When the second push rods (47, 48) are downwardly moved, the second junction rod (54) is pressed and moved by the second push rod (48), to press the second drawing die (43). Consequently, the second drawing die (43) forms a second-stage drawn part in the workpiece (42). Thus, a plurality of stages of drawn parts can be formed by the same machine. A large number of holes (51, 52) may be provided in a junction die (55) for receiving junction rods (53), to insert the junction rods (53) in only prescribed ones of the holes. When the second drawing die (43) is changed in configuration or size, the positions of the junction rods (53) are also changed in response. Thus, jigs and tools can be efficiently exchanged in a short time in order to upper die with different patterns of drawing.

Patent CA-2011032-A1 (CA)
Title: Laminated packaging film
Inventor: BALLONI RICCARDO
IPC: B32B15/08
Filed: 1990-02-27
Abstract: A polymer film laminate is provided having improved machinability on modern high speed belt drive machines, particularly when these machines are set up to form lap back seals.      A method of assembling such a film is also provided. The film includes an outside web having an upper surface layer containing a silicone oil. This laminating web can be used with virtually any co-laminate, metallized or not, which is bonded thereto with an adhesive. Upon winding the composite film laminate upon a core, silicone oil is transferred to the inside surface of the laminate, thus providing an inside coefficient of friction which is about equal to or less than the outside coefficient of friction. Hot slip properties are also improved upon such transfer. The outside and inside webs are independently formed, which allows the inside web to include coatings or film layers which are not ordinarily usable in a silicone oil-containing film.

Patent CA-2024065-A1 (CA)
Title: Connector assemblies for optical fiber light cables
Inventor: PARKER JEFFERY R
IPC: G02B6/04
Filed: 1990-08-27
Abstract: A connector assembly (5, 5') includes buffer material (16, 16') surrounding the optical fibers (11, 11') at one end of an optical fiber light cable (3) and a ferrule (17, 17') crimped onto the buffer material (16, 16') which squeezes the buffer material and packs the optical fiber ends substantially solid. During the crimping operation, the buffer material protects the optical fibers from the ferrule while permitting the optical fibers to be deformed to a desired cross-sectional shape, for example, to that of a polygon so they are packed more solid. Different types of shielding (46, 48, 50, 55) may be used to prevent light from a light source from striking selected areas of the polished end of the connector assembly (5') including particularly the buffer material (16') and, if desired, a surrounding ferrule (17') to reduce heat build-up in the connector assembly (5') so that more light energy can be transmitted through the light cable (3) without overheating.

Abstract: 2,716-005 METHOD AND APPARATUS FOR THE TREATMENT OF CANCER                           ABSTRACT OF THE DISCLOSURE     A method and apparatus for therapeutically treating cancer is provided.   The  apparatus  includes  a  magnetic  field  generator  for producing  a  controlled,  fluctuating,  directionally  oriented  magnetic field parallel to a predetermined axis projecting through a malignant neoplasm.   In one aspect, a field detector measures the magnetic flux density along the predetermined axis.

This  ratio  is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field after nulling  out  the  local magnetic  field at  that region  containing  the neoplasm.  In one aspect, a synergistic therapeutic cancer treatment is obtained  by  exposing  cancer  cells  to  the  magnetic  fields  of  the invention in the presence of a chemotherapeutic cancer agent.

Title: Apparatus and method for a smooth transition between calibrated airspeed control of an aircraft and mach number control of an aircraft
Inventor: KAHLER JEFFREY A
IPC: B64C17/00
Filed: 1991-02-20
Abstract: Apparatus and an associated method are described for an aircraft for providing an auto-changeover procedure from a calibrated airspeed control parameter to a Mach number control parameter when the aircraft is ascending and from a Mach number control parameter to a calibrated airspeed parameter when the aircraft is descending. The auto-changeover procedure is responsive to application of preselected calibrated airspeed and Mach number parameters. The data processing unit of the aircraft provides a continually updated prediction of the target parameter that would result should the aircraft execute the auto-changeover under the currently existing conditions. then the predicted value and the preselected value are equal, the changeover procedure is invoked, reducing the transients resulting from overshoot of the target parameter value. Provision is made for the circumstance when the changeover is determined by an altitude rather than a target parameter. Approximation equations for reducing the computational requirements are discussed.

Filed: 1991-04-26
Abstract: A precision resistor is formed in an integrated circuit by a diffused region created at the same time as transistor source/drain regions.  In a CMOS process, this N-type resistor region is formed in an N-well,  as is used for P-channel transistors.   The resistor formed using a deposited oxide layer as a mask, and this oxide layer is also used to create sidewall spacers for the transistor gates.   The sidewall spacers are used in creating self-aligned silicided areas over the source/drain regions, self-aligned with the gates, and the silicide is also used for contact areas for the resistor.  The value of the resistor is defined by the width of the deposited oxide layer left as a mask, but this does not require any critical alignment steps.
