摘要:
The disclosure relates to a solar cell cover (30) comprising a substrate (32) that transmits the spectral region to which the solar cell (39) responds and a multilayer infrared-reflecting coating (34) which incorporates means for suppressing low order reflections. The multilayer coating reflects one or both substrate surfaces. The multilayer coating reflects spectral bands which are adjacent to the short- and long- wavelength limits of the spectral response of the cell. The upper limit wavelength of the short-wavelength reflection band and the lower wavelength limit of the long-wavelength reflection band are independent and may be separately specified.

The disclosure relates to an electrostatic discharge device (12), painlessly discharges electrostatic energy from a computer operator and/or an optical element such as a filter (10) mounted on a cathode ray tube (CRT) computer monitor (11). The electrostatic discharge device (12) preferably is mounted on the frame (13) of the optical filter, and includes an electrostatic discharge pad circuit (12A) which includes a discharge pad (20) comprising a substrate (22) coated with a condutive material (21) and connected to ground (32) . A person such as a computer operator who contacts the coated substrate is discharged of any electrostatic charge through the coated substrate, to ground. A display (14) to indicate the discharge can be connected between the discharge pad and ground and in parallel with a resistor to control the rate of discharge through the display. the device also includes an electrostatic field drain circuit (12B) for discharging electrostatic energy emanating from the face of a CRT monitor. The field drain includes a transparent, electrically conductive coating (17) which is formed on the face of the optical filter and is connected to an input terminal of a display, the output terminal of which is connected to ground (32). Electrostatic charge emitted from the monitor and deposited on the filter is transmitted through the display, which indicates the discharge, to ground.

The disclosure relates to a respositionable, self-adhering optical laminate (10) having a thin film optical coating (15), an organic hardcoat (14), a thin plastic film substrate (11), an optical quality, pressure sensitive adhesive (12) and, preferably, a release liner (13). The pressure-sensitive adhesive is low modulus, self-wetting elastomer which readily wets glass and plastic surfaces such as video display screens, promoting bubble-free mounting. The adhesive has low tack so that bubbles can be removed easily and the laminate can be totally or partially removed and reapplied to correct its positioning and/or to remove bubbles, dirt, etc.

A substrate holder (41) is mounted within the vacuum chamber (29) for carrying at least one substrate; an electrically conductive crucible (30) is positioned within said vacuum chamber and is electrically insulated therefrom but has a low electrical resistance connection therebetween. The crucible is adapted to contain a preselected material for evaporation onto a substrate on the substrate holder. A high voltage electron beam source is positioned within said vacuum chamber in the vicinity of said crucible and includes a high voltage electron gun (31) and a deflection magnet system (53) arranged for bending electrons from said gun into said crucible for evaporating the preselected material therein, the magnet system forms a magnet field of prearranged characterisitics in the region above said crucible. A low voltage, high current plasma source (32), including a separate plasma generating chamber (35) is positioned relative to said vacuum chamber (29) to produce an intense first plasma of a selected activation gas species in said plasma generating chamber for injection into said vacuum chamber. The plasma source is positioned at any convenient location relative to the crucible and the electron beam source and is electrically interconnected with the crucible for current flow therebetween. The plasma source fills the vacuum chamber with a generally distributed plasma (36). The distributed plasma coacts with a magnetic field above said crucible and evaporant material leaving the crucible to form an intense second plasma in the region above said crucible, thereby activating the evaporant material passing through the region toward the substrate to produce a vacuum deposited thin film having improved thin film characteristics.

An antistatic antireflection optical coating (19) has a composite high index of refraction layer (19B) including a thin layer of a high index conductive material such as indium-tin oxide representing less than 25% of the optical thickness of the composite high index layer. This coating is useful in preventing static change effects on face panels of cathode ray tubes.
摘要:
Apparatus and method for producing an activated gas plasma in an evacuated working chamber (10). A substantially closed source chamber (20) is mounted adjacent one wall (11) of a working chamber (10) and has a small aperture nozzle (22) extenting through the wall (11) to communicate . gas between the source chamber (20) and the working chamber (10). A.selected gas is supplied to the source chamber (20) at a pressure substantially greater than the pressure in the working chamber (10) to produce a high velocity stream of gas entering the working chamber (10) through the nozzle (22). The selected gas is activated in the source chamber (20) before exiting through the nozzle (22) so that a high velocity stream of activated gas molecules is produced. An anode (12) is positioned within the working chamber (10) to produce a continuous gas discharge in the activated gas plasma. Various exemplary applications for enchancing chemical reactions within the working chamber (10) are discussed. In one version of the invention an elongated magnetic field is used to confine the plasma stream to a narrow beam and an anode is provided for producing a sustained gas discharge in the confined plasma stream. Further magnetic field arrangements (160, 170) are provided to configure and/or direct the plasma beam to impinge on one or more work pieces, evaporation source, or substrates.
