Abstract: A system for coding photographic materials is provided wherein a code pattern disposed on a cassette containing photosensitive material is read by an optical code reading unit associated with a photographic apparatus adapted to receive the cassette. Preferably, a grey reference patch is provided and the code is a tertiary code defined by black, white and grey printed patches. The type of photosensitive material contained in the cassette is identified from the tertiary code and appropriate exposure and/or development settings can be made by the photographic apparatus. The absence of a recognizable code pattern indicates use of an authorized supply material.

Abstract: A method is disclosed of making an on-line gas analysis of a multicomponent gas emission flow by (a) continuously sequestering a sample flow from the gas emission flow, which sample flow has been filtered to substantially eliminate solid or liquid particles, diluted to lower its dew point to below room temperature, and changed in either temperature and/or pressure to be substantially the same in temperature and pressure as that of gases used to create reference transmission frequency spectral data deployed in step (d); (b) continuously irradiating the sample flow with an electromagnetic radiation beam while modulating the amplitude of infrared frequencies in the audio frequency range of the beam, either prior to or immediately subsequent to irradiation of the sample flow, to produce electromagnetic signals having discernible amplitude variations resulting from spectral interference patterns; (c) detecting and collecting the signals at a sufficiently high rate to substantially completely distinguish between adjacent spectral pattern amplitude peaks without mutual spectral interference and to permit analysis of the signals in real time; and (d) analyzing the signals in real time by (i) mathematically manipulating the signals in accordance with Beer's Law to create reformed background-corrected data, and (ii) applying reference transmission frequency spectral data to the reformed data for each suspected gaseous component to give a linear quantitative measure of the presence of each and every suspected gas component in the gas emission flow.

Abstract: A fine pattern having a high aspect ratio is precisely formed using a focused-ion beam system (10) by depositing a pattern using an ion beam and a reactive gas, detecting an image of the deposited pattern with the ion beam in the absence of the gas, comparing the image of the deposited pattern with data of a required pattern to be formed, and removing any excess portion of the dposited pattern again by use of the ion beam. If necessary, depositing a further portion is deposited and the removal step is repeated. The deposited pattern removal step sharpens up the aspect ratio of the deposited pattern and reduces its line width.

Abstract: A method for producing para-aramid pulp includes forming a liquid, actively-polymerizing solution and subjecting the solution to orienting flow which produces an optically anisotropic liquid solution with polymer chains oriented in the direction of the flow. When the solution has a viscosity sufficient to maintain the orientation of the polymer chains, the solution is incubated until it gels. The gel is cut transversely at intervals and para-aramid pulp is isolated from the gel. Para-aramid pulp produced by the process can be used similarly to pulp produced from spun fiber.

Abstract: A low current CMOS translator arrangement is disclosed that utilizes a low current inverting stage (102), having a peak current requirement, fed by a constant current source (104) at a supply node (+V) that also has a capacitor (106) coupled to it. This low current inverter (102) is useful for a number of applications, including generating a sinusoidal signal when it is coupled to a crystal. When one or more are cascaded and coupled to a square wave input signal, the arrangement becomes a low current translator that level-shifts, or translates, the input signal having a first voltage range to a translated square wave output signal having a second voltage range. 
     In another embodiment called a low current squaring translator, a squaring stage is coupled between the low current inverter and a low current translator that includes one or more inverting stage.s This arrangement is able to achieve an output signal that maintains a precise duty cycle with low noise at a very low current.

Abstract: A method for coordinating recursive requests and responses in the peer-to-peer processing of a distributed application across a synchronous request/response interface. The method utilizes, on each side of the interface, a decision table and a local LIFO stack of generated and received requests, responses, and input from the application. The local stack is run in a push-pop manner and assists the local decision table in conducting the peer- to-peer processing until the LIFO stack becomes exhausted. A fault on either side of the interface results in undoing the processing by unwinding each stack back to a predetermined point. If one side operates as a persistent server, its application program environment is saved from one request to another by a dynamic save and simulated return to the application. Lastly, a request/demand is substituted for a demand/request by the server so as to change the server and requester roles of either side of the interface.

Inventor: DIAS FLEMING J
IPC: H04R17/00
Filed: 1990-01-10
Abstract: An improved annular array sensor [10] that facilitates hermetic sealing and uses optimum acoustic matching layers is disclosed. The key to the performance improvement obtained in the present invention is the method of forming the annular elements [38,40] of the array. In one approach, the elements [38,40] are not quite separated from one another at the concave side [14] of the sensor shell [12]. A series of cuts [34] are made into a shell [12] of piezoelectric material from its convex side [16]. These cuts [34] are made almost entirely through the shell [12] so that a small amount of material [20] remains between the cut and the concave side [14]. After poling, the resulting ultrasonic sensor [10] has the basic electrical properties of a conventional sensor in which the cuts are made completely through the shell [12]. However, the continuous concave side [14] of the ultrasonic sensor [10] need not be sealed. A conductive coating [32] on the concave side [14] serves as a common ground for all the array elements [38,40]. In another embodiment, the concave side is grooved and plated with a conductive layer [60]. Then a series of thin-kerfed circular cuts [62] are made from the convex side [16] so that they intersect the relatively thick grooves [56]. The thick conducting layer [60) serves as both common ground and mechanical support structure. In the previous art, the conductive coating would be required to have good impedance matching properties, in addition to adequate conductivity. In either embodiment of the present invention, when an impedance matching layer [41] is selected for application to the concave side [14], no compromises need be made in its properties. Therefore the impedance match can be optimized, and the material used need not be an electrical conductor. To complete the sensor airay, individual electrical conductors [42] are connected to the annuli [40] and central disc [38], at the convex side [16]. An acoustically attenuating layer [41] may be used on the convex side [16].
