Patent CA-2130925-A1 (CA)
Inventor: YAMAZAKI SEIICHI
IPC: B29C45/14
Filed: 1993-12-27
Abstract: The present invention relates to a method and apparatus for producing insert molded articles. The method is comprised of the steps of preforming a patterned insert material clamped at end parts thereof by a clamping unit into a predetermined shape corresponding to the shape of a cavity formation face of a male die or a female die of an injection molding die by a preforming unit. The insert material is then trimmed to remove the unnecessary portion of the preformed material. A trimming unit accomplishes this step. The trimming is done so as not to allow the insert material to project from the peripheral edge of the surface of a three dimensional molded article to be formed of molding resin. The preformed and trimmed insert material is then set at the cavity formation face of the male or female die of the injection molding die.      The male and female dies are then clamped to form a cavity by the cavity formation faces. Resin is then injected into the cavity to produce the article. The article is taken from the injection molding die after the molding resin is cooled and softened. At the preforming time, a preforming die having a projecting part corresponding in shape to the cavity formation face of the injection molding die is used, so that the patterned insert material can be preformed corresponding to the shape of the projecting part of the preforming die.      Moreover, prior to the preforming of the patterned inset material, the patterned insert material can be heated and softened after, before, or while being held in touch with the top face of the projecting part of the preforming die, so that the patterned insert material is preformed to trace the projecting part of the preforming die.
Patent CA-2131890-A1 (CA)
Inventor: LOEFMARK BENGT GUSTAV
IPC: H03H21/00
Filed: 1993-03-11
Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a method for avoiding self-oscillation in a four-wire loop in conjunction with echo cancellation effected with the aid of an adaptive filter. Self-oscillation is avoided for both long and short connections and also when signaling with narrow-band signals, by restricting the permitted range of the coefficients of the adaptive filter in a manner such that the absolute value of the filter transfer function will be sufficiently small for amplication in the four-wire loop to be less than one.  This is achieved by limiting the absolute value of the filter transfer function [Hca], to a value which is smaller than a determined function of the echo transfer function (Hfa) in the far-end of the loop and the echo transfer function Hne in the near-end of the loop.

Abstract: Apparatus  and  method  for  expanding  tubular members, such as U-shaped heat transfer tubes having ends thereof located in the confined space adjacent the curved sides of the bowl-shaped lower plenum of a typical nuclear steam generator.    The  apparatus  includes  an  elongate mandrel having a flow channel therethrough in communication with a resilient tubular bladder surrounding the mandrel. The bladder is flexible about its longitudinal axis due to the ribbed construction of the wall thereof.  The mandrel includes a plurality of segments,  adjacent ones of the segments interconnected by a ball-and-socket joint therebe-tween, so that the segments swivel about respective ones of the ball-and-socket joints.   In this manner, the mandrel flexes as it is inserted into the tube end located in the confined space defined by the sides of the bowl-shaped lower plenum of the steam generator.   The mandrel also flexes as it traverses the upper U-bend portion of the tube.  Thus, the mandrel and the expandable bladder con-nected thereto are flexible rather than rigid in order to be easily inserted into the tube ends located adjacent the curved sides of the bowl-shaped plenum and in order to easily traverse the upper U-bend portion of the tube.  A pressurizer supplies pressurized fluid to the channel to controllably expand the bladder into intimate engagement with the tube in order to radially expand the tube.  The mandrel  is  also capable of  similarly expanding repair sleeves disposed concentrically in the tube.

Abstract: Analog signals representing individual digital values (+3,+1, -1,-3) of data pass through a telephone line to a receiver. These signal may first be provided in a pseudo random sequence. A linear echo canceller and a first adder at the receiver simultaneously eliminate, to some extend, echo signals resulting from second analog signals transmitted through the telephone line by the receiver. A non-linear echo canceller and a second adder further  significantly reduce the echo signals and specifically reduce non-linear components in the echos signals. Adjustable signal delays achieve optimal performance of the linear and non-linear echo cancellers. In one inventive embodiment, each echo canceller includes a memory which stores, for each terminal in such echo canceller, data representing (a) the pseudo random sequence and (b) coefficients for adjusting the signals in such sequence. Such data for each terminal in such echo canceller is recorded in the memory for introduction to the next terminal in the memory.    For each terminal in such echo canceller, the signals representing the data for the coefficient and the output from the associated adder are processed to determine an adjusted value of such coefficient for storage in the memory and for use in the next cycle of processing. The adjusted coefficient value and the data stored in the memory for such terminal are processed to produce signals for introduction to the associated adder. The signals from the second adder are processed to restore the data transmitted through the telephone line to the receiver.
