Patent CA-2302658-A1 (CA)
Inventor: KAJI TAKAYUKI
IPC: B21B37/28
Filed: 2000-03-28
Abstract: During rolling with a rolling mill, which includes a sheet shape altering device capable of altering a mechanical sheet crown, while the sheet shape altering device is operated correspondingly with a target mechanical sheet crown set value during the dimensional alteration in rolling, the invention enables a stable sheet shape to be achieved, even when the mechanical sheet crown is altered to a large extent during rolling.      Specifically, the target mechanical sheet crown set value, during the dimensional alteration in rolling, is previously set based on target mechanical sheet crown set values, before and after the dimensional alteration, prior to start of the dimensional alteration in rolling. The sheet shape altering device is then operated so that an actual mechanical sheet crown, during the dimensional alteration in rolling, is equal to the target mechanical sheet crown set value during the dimensional alteration in rolling.

Title: Distributed gain line driver amplifier
Inventor: SHULMAN DIMA DAVID
IPC: H03F3/68
Filed: 2000-04-19
Abstract: A line driver amplifier is implemented by employing amplifier stages including a plurality of output transistors and a corresponding plurality of auxiliary amplifiers. The output transistor and auxiliary amplifier pairs are connected in parallel.  Each of the auxiliary amplifiers includes a built in voltage offset, beginning with an auxiliary amplifier having the smallest voltage offset to the auxiliary amplifier having the largest offset. The individual auxiliary amplifiers maintain their corresponding output transistors in an OFF state so long as the overall amplifier input signal has a magnitude less than the auxiliary amplifier offset voltage level. When the input signal magnitude level is equal to or greater than the offset voltage level of an auxiliary amplifier, that auxiliary amplifier turns its corresponding output transistor to an ON state.  Thus, for lower magnitude input signals fewer than all of the output transistors are in an ON state, while for maximum magnitude input signals all of the output transistors are in an ON state. Use of the auxiliary amplifier-output transistor pairs allows use of smaller size transistors, each of which has a lower output current than an equivalent single output transistor. Since all of the output transistors in each amplifier stage are connected in parallel, the amplifier output current is the sum of the currents passing through the ON output transistors. Consequently, the linearity of the overall amplifier structure is significantly improved in the frequency domain. In one embodiment of the invention the auxiliary amplifier offset voltage levels are fixed, while in another embodiment of the invention the offset voltage levels of the auxiliary amplifiers are adjustable, e.g., programmable.

IPC: A61B3/12
Filed: 1998-10-20
Abstract: Apparatus and method are provided for assessing direction of fixation of an eye by detecting polarization related changes in light retro-reflected from the fundus of the eye. By assessment of polarization related changes in retro-reflected light from multiple retinal areas either sequentially or simultaneously, characteristic bi-refringence signatures of portions of the retina can be identified which are used to assess the direction of fixation of the eye. Interference from corneal bi-refringence is reduced using incident light having a polarization state that is substantially independent of meridional direction. Light source (55) provides a diverging beam of polarized light on faceted prism (56). Mask (57) containing seven round apertures is placed adjacent to faceted prism (56) to isolate seven round beams of light. Light retro-reflected from eye (58) is partially reflected by beam splitter (59) which is imaged by lens (60) onto the detection system including polarizing beam splitter (61), and six element detectors (62, 63).

Title: Echo canceller having improved non-linear processor
Inventor: FARRELL DAVID S
IPC: H04B3/23
Filed: 1998-11-13
Abstract: A non-linear processor (300) for use in an echo canceller (25) is set forth.  The non-linear processor (300) includes a center clipping digital filter receiving an echo compensated signal. The non-linear processor provides a center clipped output signal having non-linear thresholds at values of + T(sub NLP) and -T(sub NLP).The value of T(sub NLP) is dynamically dependent, at least, in part on echo return loss measurements. To limit the processor's susceptibility to corruption from double-talk conditions, the non-linear processor (300) inhibits the dynamic setting of the T(sub NLP) value when a double talk condition is present. Additionally, or in the alternative, the non-linear processor (300) locks the value of the echo return loss measurement after a predetermined number of consecutive echo return loss measurements have values falling within a predetermined range of one another. Such locking further reduces the susceptibility of the non-linear processor to corruption from double-talk conditions.

Abstract: The present invention relates to a high-temperature superconductor arrangement which is protected against hot spots. A contact-making layer 4 is provided between a superconductor layer 1 and an electrical bypass 2, which contact-making layer 4 has anisotropic electrical conductivity. This ensures a low contact resistance between the superconductor 1 and the bypass 2, without the admittance being increased in the main current flow direction 3. The said anisotropy is produced by discontinuities in the contact-making layer 4, for example by said contact-making layer 4 being broken down into areas 41 which are not connected to one another.        Furthermore, a two-stage method is specified for producing an arrangement according to the invention. In this case, firstly, the contact-making layer 4 is applied to the superconductor 1 by means of co-sintering or post-sintering processes, and is then bonded or soldered to the bypass 2 via an intermediate layer 5.
