Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus which has significant advantages over other methods, such as plasma and electron showers and plasma flood system, for neutralizing excess charge due to ion implantation. SOLUTION: A means of neutralizing the excess charge on workpieces, such as semiconductor wafers, that results from ion-implantation processes, wherein the excess positive charge on a small area of the workpiece surface is locally sensed, and in response, an appropriate dose of charge-compensating electrons is delivered from an electron emission source to the area of excess charge on the workpiece. A charge-sensing probe and a voltage-controlled electron generator array are configurationally and operatively coupled in a closed feedback loop, and are made to scan the surface of the workpiece, in close but non-contacting proximity to the surface of the workpiece. Arrays of charge-sensing probes and electron generator arrays can be configured for rapid coverage of the implanted areas of the workpiece. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a reflectron lens of a simple structure and enabled to be manufactured at low cost and at the same time, with sensitivity and resolution improved, and provide a direction inversion method of ion beams using the lens. SOLUTION: The reflectron-lenses 500, 600, 650 are composed of tubes, and the tubes have a continuous conductive face each along a longitudinal direction in order to provide inside the tube an electric field in which strength varies along the longitudinal direction. The tube may be formed of glass containing metal ions such as lead, and the conductive face can be formed by reducing the glass. As for the direction inversion method of the ion beams, the ion beams are introduced into a first end part of a dielectric tube having the continuous conductive face along the longitudinal direction of the tube, and an electric field gradient in which strength varies along the longitudinal direction of the tube is formed by applying electrical potential passing through the tube, and the ions are taken outside via the first end part of the tube by inverting the direction of the movement of the ions in that electric field gradient.

Abstract:
PURPOSE: To improve efficiency by making a closed circuit television maintenance monitor system easy to use by using four mechanical actuators for moving an especially formed star cam for operating the other cam with which an invert switch actuator is engaged. CONSTITUTION: A star cam 26 is automatically inverted through manual switching in cooperation with a 2nd special cam 28. This 2nd cam 28 is fitted to the same shaft as the star cam 26 and formed almost circular. Then, an actuator 32 of an ordinary electric limit switch 30 is placed on the tableland- shaped section of the 2nd cam 28, and this limit switch 30 is constituted so as to change its state only when first arriving at one side of the tableland- shaped section positioned outside but not to change the state when separating from that tableland-shaped section. Thus, an operator can control the camera under ordinary panning operation by himself/herself and when recovering the original automatic panning operation of a system, a certain place is prevented from disabling the monitor.
Abstract:
PURPOSE: To accomplish improvement in collecting efficiency of a tube, reduction of a total transfer time, and miniaturization of a photomultiplier and the tube as a whole by comprising a plurality of concentric housing electrodes serving as sections of elliptic dome substantially. CONSTITUTION: A photo multiplier tube is constructed of an envelope 12, a face plate 14, a photoelectric emission cathode 16, a photomultiplier structure 18, the first dynode 20, a facing electrode structure 32, focusing electrodes 34, 36, 38, and an evaporator 42. Main segments, which are provided with faces tilted by tilting angles of at least 10 degrees and formed into ellipses or spheroids, are arranged from the photomultiplier part 18 to the photoelectric emission cathode 16 so that their diameters are increased in order while voltage is lowered in order. These focusing electrodes 32 form a precise electric field. In this way, collecting efficiency of the tube can be increased, a total transfer time can be reduced, and the photomultiplier tube 18 and the tube as a whole can be miniaturized.

Abstract:
A coalignment system including wedge-prism assembly that can be attached to a conventional night vision scope, for example. This could allow a standard handheld night vision scope to be deployed in different modes such as on headmounted goggles or as an augmentation scope in front of a day sight a weapon while enabling Line of sight/point of impact (LOS/POI) correction. In order to ensure maximum compatibility, the coalignment system includes diopter adjustment.
Abstract:
A photomultiplier tube having an ion suppression electrode positioned between a photocathode and an electron multiplying device in the photomultiplier tube is disclosed. The ion suppression electrode includes a grid that is configured to provide sufficient rigidity to avoid deformation during operation of the photomultiplier tube. The photomultiplier tube also includes a source of electric potential connected to the electron multiplying device and to the ion suppression electrode to provide a first voltage to the second electrode and a second voltage to the suppression grid electrode wherein the second voltage has a magnitude equal to or greater than the magnitude of the first voltage. A method of making the photomultiplier and a method of using it are also disclosed.
Abstract:
A mounting system for night vision tubes includes a multi-part sleeve that opens in the manner of a clamshell to receive the tube. The sleeve includes a longitudinal seam or a partial longitudinal seam and opens around compliant hinge regions. The night vision tube engages a ramp section of the sleeve, urging the sleeve to open and then abuts against a front shoulder, causing the sleeve to clamp shut around the night vision tube. The tube is constrained between the front shoulder and a retaining shoulder. An indexing pin engages the night vision tube and the sleeve to maintain mutual rotational alignment. The sleeve and the tube are inserted into a housing of a night vision system.
