Abstract: A headrest for supporting a person's head comprising a semi-rigid formed pillow element having two similar, spaced apart side sections and a central section connecting these side sections. The front of each side section is convexly curved in a horizontal direction and the side sections have a height substantially greater than the height of the central section which extends between the lower halves of the side sections. The headrest is manufactured by joining two layers of cloth material to opposite sides of a sheet of dual density polyethylene by flame lamination. The combined material is thermally molded into the headrest.

Abstract: A conductive film deposition rate monitoring method for measuring the real time deposition rate of a metallic deposition process particularly an electroless plating bath, including the steps of positioning an eddy current detector within a predetermined distance of a test surface where the deposition is to be deposited, and the step of monitoring the output of the detector. The apparatus comprises an eddy current sensor and a non-metallic housing for the sensor, having a non-conductive wall of predetermined thickness between the sensor and the surface of the wall distant from the sensor, the distant wall being immersed in the deposition environment, such as a plating bath, so that a deposit takes place on the distant surface, and measuring means connected to the output of the sensor for measuring the amplitude and rate of change of the output of the sensor.

Abstract: A displacement compensating module is disclosed wherein a blocking article, such as a polyimide tape, is disposed between an epoxy composition and the back surface of a substrate and between the epoxy composition and the inner surface of a cap for blocking the movement of the epoxy composition into a gap area during the manufacture of the module. An electronic module comprises a substrate, an integrated circuit chip disposed on the substrate, a cap disposed over and enclosing the chip and the substrate, a heat dissipator disposed between the cap and the chip for carrying away the heat dissipated by the chip, and an epoxy composition secured to the back surface of the substrate for sealing the module, and specifically, the chip within the module from harmful external influences. The boundary of a gap is defined by the edge of the substrate and the inner surface of the cap.
