Patent EP-0280539-A1 (EP)
Inventor: YAMAZAKI SHUNPEI
IPC: C23C16/26
Filed: 1988-02-24
Abstract: The inside of the reaction chamber of a CVD apparatus is cleaned after deposition of a carbon film. When crystalline carbon or diamond-like carbon is formed in the chamber, undesirable carbon deposits form on the inside of the reaction chamber. The sticky carbon deposits are removed in accordance with the invention by etching, making use of oxygen or an oxygen compound gas rather than a fluorine or chlorine compound gas which tends to damage the inside of the reaction chamber.

IPC: G03B27/62
Filed: 1988-05-17
Abstract: An electro-photographic machine has a light source 21 and a reflector 22 to illuminate a line on an original to be copied and carried on a movable table 9. Light is absorbed by text on the original and reflected by non-text background through an optical lens 5 and a slit between stops 6 onto the photosensitive surface 7 of a revolving drum. The surface is previously charged at 23 and subsequently toner 25 is applied to adhere to the non-exposed areas. This is then transferred to plain paper by a transfer charger 28 and fixed in rollers 30. The invention replaces the original by a reflective type optical modulation element 10 having a liquid crystal material between a common electrode and a series of separately energisable electrodes, so that electric signals applied to the electrodes change the reflection characteristics of the liquid crystal to reflect light through the lens 5 or not, in accordance with the desired images for reproduction.

Abstract: The arrangement comprises a tracking sensor with a light source, an optical means and a receiver with two photosensitive detectors, as well as a measuring apparatus with a computing unit. The optical means focuses light to provide a beam which falls on a moving web of foil. The tracking sensor may, for example, be installed in a re-winding installation, and during re-winding of the web, senses by means of the beam a marking track which is embossed in the web in the longitudinal direction of the web and which is composed of two different diffraction grating tracks. Each diffraction grating track projects the light diffracted therefrom in a predetermined direction of incidence to a respective detector. The sensed signals supplied by the receiver are converted into a difference signal by the measuring apparatus, and processed to provide correction signals which are supplied to a control means of the re-winding installation in order to compensate for lateral deviation of the moving web of foil.
