Title: Vacuum treatment apparatus
Inventor: SCHERTLER ROMAN
IPC: C23C14/56
Filed: 1992-05-29
Granted: 2000-03-15
Abstract: The invention proceeds from a vacuum process apparatus for an article which is processed or treated, resp. at two stations, whereby each station has a charging and/or removing opening for the article. A transporting device is supported for rotation and includes a supporting portion which is successively moved onto the openings of the stations. The process plant is designed in such a manner that the surface normals determined by the surfaces of the openings and the space axis defined by the axis of rotation of the transport device do not run parallel and rather enclose together an angle of 90° or 45°. By such an arrangement it is possible to design extremely compact vacuum vapor deposition apparatuses having a plurality of individual stations, whereby additionally short transporting distances are obtainable and the volumes to be conditioned can be minimized.

Abstract: The device consists of the fist comparing circuit which compares the reference level of bending signal with signal level from the first combination circuit that combines bending signal and horizontal synchronization signal, the first amplifying circuit which determines the amplification of bending signals by data from the first comparing circuit, the second comparing circuit which compares the reference level of color signal with the signal level from the second combination circuit that combines color signal and the level of synchronization gate pulse, the second amplifying circuit which determines the amplification of color signal by data from the second comparing circuit, and a mixed circuit which mixes bending and color signals and supplies them to a record head.
Patent KR-960009192-B1 (KR)
Title: Mn/al two-layers coated steel sheets with an excellent corrosion resistance and adhesion
Inventor: LIM BYUNG-MOON
IPC: C23C16/06
Filed: 1993-12-30
Granted: 1996-07-16
Abstract: The sheet has two coated layers on the surface of steel sheet; the lower layer of vacuum evaporated aluminum in the range of 1 to 20g/m2, and the upper layer of vacuum evaporated manganese in the range of 1 to 20g/m2. The degree of vacuum is under 5=G10-5 Torr. The temperature of board is 250deg.C. The lower layer of aluminum provides good adhesion and corrosion resistance, and the upper layer of manganese provides good heat resistance, coating property and weldability. The produced sheet is used for automobile, electric home appliances, building materials and structures requiring high corrosion resistance, adherency, and machinability.
