Abstract: An extreme ultraviolet lithography (EUVL) machine or system for producing integrated circuit (IC) components, such as transistors, formed on a substrate. The EUVL machine utilizes a laser plasma point source directed via an optical arrangement onto a mask or reticle which is reflected by a multiple mirror system onto the substrate or target. The EUVL machine operates in the 10-14 nm wavelength soft x-ray photon. Basically the EUV machine includes an evacuated source chamber, an evacuated main or project chamber interconnected by a transport tube arrangement, wherein a laser beam is directed into a plasma generator which produces an illumination beam which is directed by optics from the source chamber through the connecting tube, into the projection chamber, and onto the reticle or mask, from which a patterned beam is reflected by optics in a projection optics (PO) box mounted in the main or projection chamber onto the substrate.

Abstract: A corrosion sensor array incorporating individual elements for measuring various elements and ions, such as chloride, sulfide, copper, hydrogen (pH), etc. and elements for evaluating the instantaneous corrosion properties of structural materials. The exact combination and number of elements measured or monitored would depend upon the environmental conditions and materials used which are subject to corrosive effects. Such a corrosion monitoring system embedded in or mounted on a structure exposed to the environment would serve as an early warning system for the onset of severe corrosion problems for the structure, thus providing a safety factor as well as economic factors. The sensor array is accessed to an electronics/computational system, which provides a means for data collection and analysis.

Abstract: Broadly, the disclosure is directed to a range-measuring detonating system comprising an air-driven scanning mirror which cooperates with fixed mirrors to project the output of a laser toward a target, the laser being modulated at a given frequency by a local oscillator and modulator circuit. Adjacent the laser is a detecting means which feeds a receiver, the receiver output being in turn delivered to a detector which feeds a phase comparator to which is also applied the output of the local oscillator. The phase comparator output is coupled to an AND circuit to which is also applied the output of the detector. When the light energy returned by a target in the vicinity of the system achieves a given phase and amplitude, the phase comparator output is gated through the AND circuit to ignite a squib, booster and warhead.

Abstract: This disclosure relates to countermeasure systems, particularly to systems for providing a protective cover against homing and/or fire control devices operating upon infrared, sonar, or microwave reflected energy or for confusing search and tracking devices, and more particularly to decoy rounds and their method of fabrication. The decoy rounds include at least one load of energy generating material, means for propelling the load, a burst charge for shattering the load, the burst charge being constructed so as to cause a line type explosion, and means for igniting the burst charge.

Abstract: This disclosure relates to countermeasure systems, particularly to systems for providing a protective cover against homing and/or fire control devices operating upon infrared, sonar, or microwave reflected energy or for confusing search and tracking devices, and more particularly to decoy rounds and their method of fabrication. The decoy rounds include at least one load of energy generating material, means for propelling the load, a burst charge for shattering the load, the burst charge being constructed so as to cause a line type explosion, and means for igniting the burst charge. The decoy rounds are fabricated by a process which includes a novel method of producing the line type explosion and includes a novel assembly operation which allows the round to be exploded in such a way that birdnesting of the decoy material is minimized.

Abstract: A system which disperses a payload sequentially. The payload may consist of a number of discrete individual units or a long string of units. The illustrated and described embodiment of the system is utilized in a rocket for dispersing decoy material, such as aluminum chaff, in a sequential burst pattern. The concept may readily be applied to mortor type decoy rounds, other types of decoy material, or to other types of applications requiring a sequential dispersion of the payload thereof.

Abstract: A system which disperses a payload in a sequential manner. The payload may consist of a number of discrete individual payload units which are composed of two or more sections. The illustrated and described embodiment of the system is utilized in a rocket for dispersing decoy material, such as aluminum chaff, in a sequential burst pattern so as to produce a more uniform, widespread distribution of the decoy material. This is accomplished by sequential bursts of each unit which throw outwardly the payload sections of each unit, whereafter each of the payload sections are exploded. This concept may readily be applied to mortor type decoy rounds, other types of decoy material, or to other types of applications, requiring a sequential dispersion of the payload thereof.

Abstract: A harmonic converting or generating material, particularly adapted for use as chaff in decoy rounds, and a method of fabricating the same. The material is formed from metallic foil to have the characteristics of a dipole and which by the addition to the midpoint thereof of semiconductor or other polarizable material has the capability of reradiating incident frequencies along with radiating harmonics thereof or undesirable noise. Thus, the passive material, when activated by an active source, such as a radar unit, serves to convert or generate spurious frequencies, harmonics and noise, in addition to reradiating the fundamental frequency of the active energy source, thus giving the illusion of a plurality of independent energy sources.

Abstract: The disclosure broadly relates to a launcher system for providing a protective cover against homing devices operating upon infrared, sound navigation and ranging, and/or microwave-reflected energy. The launcher system is illustrated in one embodiment as a nine round portable system wherein the decoy rounds are selectively fired manually by nine pushbuttons located in the control box. The decoy rounds each contain an electric squib which simultaneously ignites both a lift charge and a time fuse. The lift charge propels the round from the launcher in a ballistic trajectory and the time fuse ignites a burst charge which disperses the payload at the optimum altitude for the type of round being used. Other embodiments of the system illustrate a ten round system which may also be utilized in multiples thereof, with the control therefor being located within the control section of a ship or the like and activated through an intervalometer.

Abstract: This invention relates to a servocontrol system for a weapon such as a missile which is a shoulder-launched, infrared-homing, guided missile which provides frontline troops with effective air defense against low altitude enemy aircraft. The weapon, described herein for purposes of illustration, consists of a missile and launcher combination which can be readily transported and operated within the normal environments associated with ground forces in a combat area. To meet the size, weight, and performance requirements, the missile achieves passive homing guidance by using a space-stabilized, infrared-seeking-head control system to generate guidance signals for a single-channel, variable-incidence wing control system working in conjunction with a rolling airframe.
