Abstract: An apparatus for digital radiography has a cassette adapted to obtain a digital image of a subject in response to incident radiation when receiving source power through an input power connector and adapted to provide the obtained digital image as output from a first data connector. A support tray is adapted to removably seat the cassette and has a second data connector that releasably engages with the first data connector on the cassette when the cassette is seated in the support tray. A wireless communication circuit in the support tray is energizable to transmit the digital image obtained from first data connector of the cassette to a host processor. A battery in the tray provides source power to at least the wireless communication circuit on the support tray circuitry and the input power connector of the seated cassette.

Abstract: An apparatus and method for removing stored energy from a storage phosphor screen in which a radiation image was recorded and then read by collecting stimulated emission from the phosphor sheet. The phosphor sheet is transported along a path in a first direction at a first speed into an erase area having at least one erasing light source. A portion of the phosphor sheet disposed within the erase area is exposed to the light source to affect erasure of the radiation image on the exposed portion of the phosphor sheet. Transport of the phosphor sheet is stopped when the trailing edge of the phosphor sheet enters the erase area and the phosphor sheet dwells within the erase area for a predetermined time period. The phosphor sheet is then transported along the path in a second direction at a second speed, and then transported along the path in the second direction at a third speed when the leading edge exits the erase area.

Abstract: A sheet detection system comprising: a first sheet transport for transporting a sheet along a first sheet transport path; at least second and third sheet transports for selectively transporting a sheet transported along the first sheet transport path along second and third spaced and substantially parallel sheet transport paths which branch from the first sheet transport path; a radiation source for emitting a beam of radiation which intersects the second and third sheet transport paths in the region where the second and third paths branch from the first path; a radiation detector for detecting the radiation beam; and a control for controlling the first, second and third sheet transports the radiation source and the radiation detector, such that when a sheet which is transported along the first sheet transport path by the first sheet transport is caused to be transported along one of the second or third transport paths, interruption or lack of interruption of the radiation beam by the sheet is detected by the

Abstract: An integrated transistor device operates with a linear triode vacuum tube like characteristic with a very low output impedance and a large interaction between the gate and drain potentials. The drain current of a first transistor is connected directly to the source of a second transistor which has a low input impedance matching the output impedance of the first transistor. The gate of the second transistor is held at a positive potential and functions to provide isolation of the varying drain signal from the drain of the first transistor and to provide a high impedance at the output terminal. This device structure provides high input impedance, high current gain, high output impedance and a linear operating characteristic.

Abstract: Disclosed is an integrated transistor structure having increased conductance and operating speed including a complementary insulated gate field effect transistor pair, each including a source and a drain region with a gate contact positioned therebetween, ohmic contacts to the sources, and a rectifying junction contact to each of the drain regions. The gates of the two transistors are interconnected and function as the input terminal, and the two rectifying contacts are interconnected as the output of the device. The structure includes a semiconductor substrate having slow diffusant dopants therein or implanted metal ions of cobalt, molybdenum, or tungsten. The structure further includes an epitaxial semiconductor layer with resistance on the order of 0.5 to 1.0 ohm cm and a thickness of 1.5 to 5.0 .mu.m. The device regions for the field effect transistor pair are formed in the epitaxial semiconductor layer.

Abstract: An array of electrodes for use in a flat panel display includes a plurality of electron emitters formed of polycrystalline or single crystalline silicon which has been selectively etched to form pores in the emitters. The electrode array is then electroplated in a methane plasma to deposit a carbon compound such as silicon carbide on the surfaces of the emitters and in the pores of the emitters. Each emitter has a generally flat electron emitting surface which facilitates a longer life for the electrode array, the porous structure of the emitters increasing the electron emission efficiency of the emitters in relatively low electric fields. The electrode array can be integral with a support substrate by anisotropically etching the substrate to form the emitters. A layered interconnect structure can be formed on a surface of the silicon substrate for providing the interconnect structure for the electrode array.

Abstract: A contact and interconnect structure for a semiconductor integrated circuit includes a thin layer of refractory metal on a contact surface of the substrate through an opening in an overlying insulation layer with boron ions implanted into the substrate through the layer of refractory metal and the contact surface to ensure a uniform ohmic contact. An interconnect structure is then formed on the insulation layer and on the thin layer of refractory metal including a first layer of a refractory metal nitride on the insulation layer, a second layer of refractory metal on the first layer of refractory metal nitride, and a second layer of refractory metal nitride on the second layer of refractory metal.
