Granted: 1996-05-28
Abstract: The present invention relates to a process for producing permanent domain refinement continuously and at very high line speeds in grain oriented electrical steel having an aluminum nitride inhibitor system. After the final high temperature anneal, the glass film and insulative coating on the surface is removed in narrow bands (grooves or rows of spots). The steel is electroetched to increase the depth of the bands, coated with aluminum by electrophoresis and given a stress relief anneal to bond the aluminum coating to the base metal by diffusion. A localized stress field is induced during cooling which causes domain refinement due to the differential thermal contraction between the aluminum and the base metal.

Abstract: ABSTRACT OF THE DISCLOSURE    An automatic transmission shift controlling method for preventing both excessive delays in speed ratio shifts and multiple shifts in close succession in response to two different shift commands in a short time period.  When a first shift command is issued, the input and output rotational speed ratio of a shift means associated with a first target speed range for selecting a power transmission path associated with the first target speed range and determined by the first shift command is detected, and the start of operation of the shift means associated with the first target speed range is detected by checking whether the input and output rotational speed ratio has started to vary or not.  When a second gear-shift command is issued after the first shift command has been issued but before the start of operation of the shift means is detected, the second shift command is accepted.

Abstract: ABSTRACT OF THE DISCLOSURE     A  position  sensor  including  a  guide  bar carrying a magnetic tape generating a magnetic field whose intensity   varies   sinusoidally   along   a longitudinal axis of the guide bar.  A pick-up head is mounted  adjacent  the  guide  bar  for  translational movement therealong to detect the magnetic field.  More particularly, the pick-up head comprises two magnetic field  detectors  spaced  apart  by  a  predetermined distance in the direction of  translational motion of the  pick-up  head,   each  magnetic  field  detector generating  an  output  signal  representative  of  the magnetic field intensity at the position of detection thereof.   By processing  the  output  signals  of  the magnetic field detectors, it is possible to accurately determine the position of the pick-up head with respect to the guide bar.  Advantageously, the position sensor may be used for the construction of a torque meter.

Patent CA-1335936-C (CA)
Inventor: BOURGOIN ARMAN
IPC: G09F3/02
Filed: 1989-09-29
Granted: 1995-06-20
Abstract: The present invention is directed to improvements with respect to articles which are to be folded about an edge of a substrate.  In particular, the invention is useful in multiple layer labels which have a plastic film cover of high tensile strength.  These types of labels, when wrapped about the edge of a substrate, have a tendency to return to a less folded condition and thus, the adhesive layer which maintains the label in contact with the substrate must continuously offset this internal force.  According to the present invention, this is overcome by structurally weakening the label at a predetermined location during the manufacture of the label to allow folding of the label in this predetermined location.  This structure reduces the internal stress forces which tend to urge the label to a less folded condition.  The invention also has application with respect to reinforcing films or other reinforcing materials which have a tendency, when folded, to return to a less folded condition.
