Patent EP-0342933-A2 (EP)
Inventor: FREYTSIS AVRUM
IPC: H01L21/265
Filed: 1989-05-16
Abstract: A mechanical scanning system for a batch ion implanter includes a disk for mounting wafers at sites near its periphery and a disk drive assembly for rotating the disk. The disk and the disk drive assembly are supported in an end station vacuum chamber by a scan arm which extends through a sealed opening in an access door. A scan drive assembly attached to the access door scans the scan arm and the disk in an arc-shaped path. Simultaneous rotation and scanning of the disk cause the ion beam to be distributed over the surfaces of the wafers mounted on the disk. A pivot drive assembly rotates the scan arm and the disk about a pivot axis between an implant position and a load/unload position. The implant angle can be changed without opening or venting the vacuum chamber by loosening the attachment of the scan drive assembly to the access door and rotating the scan drive assembly, the scan arm and the disk about the pivot axis. The access door can be moved on rails to an open position for access to the disk.

Abstract: A new method is provided to impart a hydrophilic lubricious coating onto articles such as medical devices. A device, for example a catheter, is first contacted with a polyisocyanate solution, to provide coupling, then contacted with a poly(carboxylic acid) solution to give a coating, and is then finally oven dried. These coatings have lubricity that only becomes manifest upon exposure to water or body fluids, and moreover, are also long lasting and have good abrasion resistance. This combination of properties is not available from other currently used or proposed coatings such as Teflon.

Abstract: 5 n7 A multiplexed signal transmitting apparatus of this invention can transmit a first image signal, which is for a screen longer in the lateral direction than a screen obtained by a conventional television signal, by converting it to a signal that can be reproduced by a receiver of a conventional scheme. A first encoder (903, 950) limits the band of the first image signal to provide a first component, and compresses the first component in the vertical direction, thereby converting the first image signal to a second image signal corresponding to a first portion of the screen of the conventional television receiver on its vertically central panel. A second encoder (300) compresses a second component, obtained by removing the first component from the first image signal, in the vertical direction, and encoding the frequency of the compressed second component to be a third image signal which can be multiplexed on second portions of the screen of the conventional television receiver on its upper and lower panels which are different from the first portion. A motion detector (121) detects image motion data by using the second image signal, controls a constant of a coefficient multiplier (119) based on the motion detection signal, and controls the level of the third image signal. A switch (928) and an adder (927) output the third image signal which is level-controlled to correspond to the upper and lower panels of the screen, and the second image signal to correspond to the vertically central panels of the screen.
