An exit window for an electron beam emitter through which electrons pass in an electron beam includes a structural foil for metal to metal bonding with the electron beam emitter. The structural foil has a central opening formed therethrough. A window layer of high thermal conductivity extends over the central opening of the structural foil and provides a high thermal conductivity region through which the electrons can pass.

Electron beam emitter

A fluid sterilization apparatus including a sterilization chamber having a cavity therein, and a nozzle for receiving pressurized fluid and directing a spray of the fluid into the cavity. An electron beam generator having an exit window is mounted to the sterilization chamber for directing a beam of electrons through the exit window and into the cavity of the sterilization chamber to irradiate the spray of fluid. The nozzle is configured to direct the spray of fluid substantially parallel and proximate to the exit window.

An exit window for an electron beam emitter through which electrons pass in an electron beam includes an exit window foil having an interior and an exterior surface with a series of holes formed therethrough. A corrosion resistant layer having high thermal conductivity extends over the exterior surface and the holes of the exit window foil for resisting corrosion and increasing thermal conductivity. The layer extending over the holes of the exit window foil provide thinner window regions which allow easier passage of the electrons through the exit window.

A telephone calling card includes a planar card member with a scratch-off label positioned on a surface of the planar card member. The scratch-off label includes a base label having an opaque, releasable film layer and a PIN printed on the opaque, releasable film layer. A scratch-off cover label is secured on the base label and has a scratch-off layer that covers the PIN to obscure from viewing the PIN. Upon application of a peeling force to remove the scratch-off cover label, the opaque, releasable film layer is removed and hides the printed PIN from viewing via the backside of the opaque, releasable film layer. In one aspect of the present invention, the scratch-off cover label is folded over the base label.

An electron accelerator includes a vacuum chamber having an electron beam exit window. The exit window is formed of metallic foil bonded in metal to metal contact with the vacuum chamber to provide a gas tight seal therebetween. The exit window is less than about 12.5 microns thick. The vacuum chamber is hermetically sealed to preserve a permanent self-sustained vacuum therein. An electron generator is positioned within the vacuum chamber for generating electrons. A housing surrounds the electron generator. The housing has an electron permeable region formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window.

A rigid magnetic memory disc (,) is disclosed having a substantially flat, central hard core substrate (,) and an overlying smoothing layer (,) deposited thereon. The smoothing layer (,) is subsequently polished to a predetermined thickness. The smoothing layer (,) should be capable of having a surface finish better than approximately ten Angstroms Ra. After the smoothing layer (,) is polished, an appropriate magnetic medium (,) and alternately, a nonmagnetic finishing layer (,) are then applied to the rigid disc substrate (,) as necessary, ultimately rendering a finished magnetic disc. The flatness of the underlying central hard core substrate (,) and the flatness and smoothness of the smoothing layer (,), the overlying magnetic medium (,) and the overlying finishing layer (,) allows the read-write head (,) to pass over the magnetic medium (,), or the finishing layer (,), if present, at both a substantially constant and substantially low flying height, thus increasing the areal density of the rigid magnetic memory disc (,). Preferably, the typical flying height of the read-write head (,) is approximately less than two and one-half microinches.

A rigid magnetic memory disc(28) is disclosed having a substantially flat, central hard core substrate(12) and an overlying smoothing layer(14) deposited thereon. The smoothing layer(14) is subsequently polished to a predetermined thickness. The smoothing layer(14) should be capable of having a surface finish better than approximately ten Angstroms Ra. After the smoothing layer(14) is polished, an appropriate magnetic medium(16) and alternately, a nonmagnetic finishing layer(16) are then applied to the rigid disc substrate(10) as necessary, ultimately rendering a finished magnetic disc. The flatness of the underlying central hard core substrate(12) and the flatness and smoothness of the smoothing layer(14), the overlying magnetic medium(16) and the overlying finishing layer(18) allows the read-write head(24) to pass over the magnetic medium(16),or the finishing layer(18), if present, at both a substantially constant and substantially low flying height, thus increasing the areal density of the rigid magnetic memory disc(28). Preferably, the typical flying height of the read-write head(24) is approximately less than two and one-half microinches.
