Split-Pea Circuit. The transistor took the complicated network of wires in a vacuum tube and condensed it into a simple, solid piece of silicon or germanium; the microcircuit reduces an entire electronic circuit composed of dozens of transistors and other components to a tiny latticework of thin metal conductors mounted on a base of such material as glass or silicon. At Texas Instruments, which shares leadership in the microcircuitry field with Motorola and Fairchild Camera, engineers have developed a piece of silicon the size of a split pea into which they have fused the equivalent of 38 transistors, five...
...carbon steel. Uddeholm sold batches of that steel to Gillette in the 1930s, but stainless blades did not catch on because shavers found them irregular in quality. A sudden and tremendous demand began a year ago, after Britain's Wilkinson Sword Ltd. brought out a blade coated with silicon plastic to make it smooth as well as sharp.* Wilkinson's steel comes from Uddeholm, which also supplies American Safety Razor and Schick. Under its research-minded president, Wilhelm Ekman, 51, Uddeholm has quadrupled its stainless blade output since 1961, now produces 80% to 90% of Sweden...
...from the steel experts to those shavers who take a sporting glee in eking out as many shaves as possible from a single blade: rinse but never wipe the blade, because that removes the silicon coat and causes the razor to snag on the beard...
...Tyco Laboratories, Inc. of Waltham, Mass., has developed a laser that seems to have the necessary simplicity. Invented by Drs. A. I. Mlavsky and L. B. Griffiths, it is a .02-in. cube of silicon carbide (carborundum), 4Two opposite sides are carefully polished, and electrodes are attached to antfcher two. When a weak direct current of electricity is passed through the cube, a thin line in its center glows with green-blue light. But this is not pure laser light. It is merely ordinary mixed-up light of varying frequencies. When the current passes a critical strength...
...company research moves so fast that it makes a company's own products obsolete. Du Pont's Dacron is giving tough competition to the company's nylon and rayon, and Du Pont has decided to give up making rayon altogether. General Electric's recently announced silicon transistor will sell for half the price of its own germanium transistor...
