...move was the most recent response to evidence that the work involved in creating microchips can lead to miscarriages. Other semiconductor manufacturers, such as Intel, National Semiconductor, Texas Instruments and Advanced Micro Devices, already encourage mothers-to-be to remove themselves from microchip production areas. The latest round of corporate concern originated with Digital Equipment, the computer-manufacturing firm, where a number of women production workers suffered miscarriages over the past five years. Digital commissioned a study of the problem by Harris Pastides and Edward Calabrese of the University of Massachusetts at Amherst's division of public health...
...perfect efficiency, which would make an optical computer 1,000 times as fast as the most advanced of modern electronic supercomputers. AT&T took a significant step toward that faraway goal in June by producing the first optical equivalent of a transistor. The Japanese, meanwhile, are developing a hybrid microchip that combines the most efficient aspects of electronics and optics. Declares Alan Huang, director of AT&T's optical computing project: "If we let the Japanese win, we might as well throw in the towel as far as computing is concerned...
...heart of the new medium. In analog recording, sound waves are transcribed as grooves onto a vinyl disc. The grooves are then traced by a diamond-tipped stylus in the tone arm of the turntable to re-create the sound. In digital recording, the music is sampled by a microchip at the rate of 44,100 times a second and expressed as a series of ones and zeros. Encoded in invisible "pits," the numbers are read by a player equipped with a laser beam, which relays the information to a microcomputer that converts the digits back to sound...
...company's main innovation is a computer microchip called a charge- coupled device, which takes the place of the film roll in the camera. The CCD, manufactured for Canon by Dallas-based Texas Instruments, converts incoming light into electronic signals that are recorded on the floppy. The disk measures only 2 in., but can store up to 50 pictures, vs. 24 to 36 images on conventional 35-mm film, and is reusable. After shooting, the photographer can pop the disk into a recorder to view the images on a TV screen or reproduce them on a special printer...
...unnecessarily cruel. Protesters marched last week in front of the USDA offices in Washington, symbolically branding one another on their right cheeks with sponges that had been dipped in paint. Some demonstrators suggested that cows could be identified with an ear tag, a tattoo or even a strategically placed microchip. Late in the week a federal district court judge in Rochester, responding to a complaint from the local Humane Society against Agriculture Secretary Richard Lyng, issued a temporary restraining order to halt the branding and directed the USDA to inform all dairymen participating in the program of his action...
