Abstract: ABSTRACT           This invention relates to the manufacture of semiconductor devices and more particularly to a method of diffusing an impurity layer into a substrate.  The disclosed method comprises the steps of placing a body of semiconductor in a vacuum doping chamber, evacuating air from the chamber, subjecting the body to a dopant in the form of a gas or vapour while simultaneously heating the chamber to at least the diffusion temperature.  The diffusion process is controlled by monitoring and controlling the pressure and the temperature of the dopant gas in the chamber.          The diffusion method can also be carried out with the further admittance of a reactive gas or with the further admittance of a second dopant gas and a reactive gas together.

Abstract: ABSTRACT:     The apparatus is characterised in that a mandrel is rotated continuously as a strip of electrical terminals (15, 15') are continuously fed to the mandrel, partially wrapped against the mandrel, and exited from the mandrel. A conduit for supplying plating fluid under pressure opens into a plurality of nozzles on the mandrel. Anode extensions are mounted within the nozzles for reciprocation into and out of the interiors of the terminals that are against the mandrel. The nozzles inject plating solution into the interiors of those terminals in which the anode extensions have been received. A source of electrical potential supplies electrical current flowing from the anode extensions through the plating solution and to the interiors of those terminals having anode extensions therein. The anode extensions are constructed for withdrawal from the interiors of those terminal prior to those terminals exiting from the mandrel.          A method for selectively plating the interior surfaces of electrical terminals and a series of terminals plated according to the invention are also disclosed.

Abstract: ABSTRACT       A bait container, particularly useful with crustacean (lobster or crab) traps is formed with an apertured side wall in which the apertures comprise at least 50% of the surface area of the side wall.  The apertures for any container are usually uniform in size and the range of aperture size is from about 1000 to about 2500 microns.  The size and distribution of the apertures prolongs bait life due to the controlled release of bait from the container and the added protection against unwanted predators such as arthopods.  Furthermore the bait container permits the use of bait produced from previously undesirable material, such as discards and non-edible fish parts taken from the fish processing industry.

Abstract: ABSTRACT:         An arrangement for recovering a clock signal of frequency 1/T from an angle-modulated carrier signal having a modulation index m = 0.5 comprises a frequency doubler, a circuit for generating a clock signal component from the frequency-doubled signal, a clock filter for selecting the generated clock signal component and a pulse shaper for producing a clock pulse signal. The arrangement produces a reliable clock signal within a very short time after the start of the signal reception, because the fre-quency doubler comprises a hard limiter, a first bandpass filter connected thereto and having a Q ? 10, a balanced modulator connected to the limiter and to the first band-pass filter and a second bandpass filter having a Q ? 10 tuned to twice the carrier frequency 2fc; and because the generating circuit comprises a frequency converter for converting the frequency-doubled signal to a frequency band around a carrier frequency fo of the order of twice the clock frequency 2/T, a bandstop filter tuned to frequency fo and having a Q ? 10 and a squaring circuit connected to the band stop filter. The arrangement is attractive for use in receivers for radio communication systems which require a very fast acquisition of the correct clock phase.
