Patent CA-1176959-A (CA)
Inventor: CHILL JAMES L
IPC: C22F1/08

Abstract: ABSTRACT OF THE DISCLOSURE         A process is provided for the forming of articles from leaded bronzes of copper alloy base having a lead content of at least 4% and which pro-cess includes cold working, in the forming of pro-ducts or articles, and specifically the forming of bearings.  Basically, the process of this invention comprises the forming of stock by chill casting tech-niques and the subsequent alternate steps of cold working and annealing the chill cast stock of pre-determined configuration in forming of a substanti-ally finished product or article having predetermined dimensions and configurations.  The alloy is first chill cast into stock of predetermined configuration and is then subjected to cold working to effect a pre-determined dimensional reduction in forming of the de-sired article.  Annealing is accomplished between cold working operations which may include more than one pass through the cold working apparatus to obtain a predeter-mined reduction prior to an annealing operation.  Also, the chill cast stock may be subjected to an annealing operation prior to the first cold working operations. Utilization of this process results in enhancement of the grain structure of these materials which are initi-ally formed by chill casting procedures as well as ef-fecting a significant increase in the tensile strength and hardness properties of such materials.

Abstract: APPARATUS FOR PRODUCING COLLATED COPIES         IN PAGE SEQUENTIAL ORDER                    ABSTRACT OF THE DISCLOSURE Apparatus for producing duplex or simplex collated copies from duplex and simplex originals comprising a copier having a duplex section with two transfer stations separated by a copy-sheet inverter.  A document feeding section circulates and recirculates original sheets, one-after-another, for pro-ducing sets of copies in page sequential order.  The document feeder is provided with a single hopper for receiving and maintaining the originals in their usual page sequence or order so that no preparation (i.e., special arrangement) of an original is necessary prior or subsequent to copying for making collated copies.  The duplexing section requires only a single fuser that is positioned so that the copy sheets pass through both transfer stations before entering the fuser, thus permit-ting transfer of images under similar conditions in both transfer stations.

Abstract: Abstract A transimpedance pre-amplifier is used in connection with optical detectors and is designed to obtain low noise, low distortion and flat frequency response simultaneously.  The amplifier design accomplishes low distortion and flat frequency response over a wide range of input signals by designing the pre-amplifier circuitry in such a manner as to compensate for the phase shift introduced by a feedback network connected across the input and output of the amplifier.  This adjustment allows the feedback network to be of such a value as to effectively control any thermal noise introduced by the feedback resistor-input capacitance system.  This compensation for the phase shift allows the phase margin and therefore stability to be controlled by means of the load impedance on the output transistor of the amplifier circuit.  The result of such new relationship is that the amplifier may be designed based upon the desired location of the pole by adjusting the feedback resistance in such a manner as to negate the effects of the thermal feedback and from such calculation the load impedance connected across the output of the transistors which comprise the amplifier section are then determined by the equations derived.

Abstract: HIGH RESOLUTION OPTICAL LITHOGRAPHY METHOD AND APPARATUS HAVING EXCIMER LASER LIGHT SOURCE AND                STIMULATED RAMAN SHIFTING                 Abstract An optical lithography method and apparatus in which a pulsed excimer laser produces at least one fundamental output which is directed to expose a photosensitive medium. The output is highly non-gaussian and has sufficient power so that full exposures can be accomplished within a few seconds.  An alternate light source is provided by directing the excimer laser output to a Raman cell having a suitable Raman medium contained therein.  At least one secondary wavelength is produced by stimulated Raman scattering and the output of the Raman cell is directed to expose a photosensitive medium.  A mixture of more than one excimer gas can also be provided in the excimer laser to produce one fundamental output for each excimer gas present in the mixture.  These outputs can be directed to expose a photosensitive medium directly.  Alternatively, these outputs can be directed to a Raman cell having either a single Raman medium or multiple Raman media in a suitable mixture and directing the output from the Raman cell to expose the photosensitive medium.

Abstract: A B S T R A C T An electron-beam array lithography (EBAL) system and method of operation is described, employing an electron beam column of the array optics type having an array lens assembly, an array fine deflector assembly and a coarse deflector assembly for selectively directing an electron beam to a desired element of the array of lenslets and its associated element of the array of fine deflectors, where one or more of the lenslets in the array may be flawed.  The method and system further comprises deriving fiducial marking signals from a lenslet stitching grid of fiducial elements, formed on a stan-dard stitching target, for calibrating the boundaries of the fields of view of the respective elements of the array of lenslets.  The fiducial marking sig-nals are used to stitch together the individual fields of view of the elements in the array of lenslets in order to cover a desired area of a workpiece sur-face to be subsequently exposed to the electron beam, for example, the surface of a semiconductor wafer upon which a plurality of integrated circuit chips are to be formed.  In the event of flawed lenslets in the array lens, the locations of those parts of the exposed area which were subject to the fields of view of flawed lenslets in the array lens assembly are mapped in a computer memory and this information is used to blank the electron beam during any period that the coarse deflector might be directing the beam to a flawed lenslet.  The system and method then physically permutes the position of the exposed target area to a net physical position subject to the field of view of a different array of lenslets.  Appropriate coarse and fine deflection signals are then obtained from the flawed lenslets, and the electron beam is then caused to retrace over these areas in accordance with the master pattern specifications for this area an the target surface whereby increased yield from the EBAL system is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE         An accordian fold molded packaging tray is disclosed having article engaging surfaces thereon which change orientation relative to articles stored in the tray such that when articles are placed in the tray such surfaces help to channel the stored articles into position within the tray and then the surfaces are rotated into engagement or proximity to such stored articles to hold the articles during subsequent shipment and storage.  This change in orientation of the article engaging surfaces is accomplished by reduction of the overall dimension of the tray which causes the article engaging surfaces to rotate about fold lines formed in the tray.

Abstract: Abstract of the Disclosure:     A pager receiver for a radio calling signal carrying a call number and/or a message comprises a processing unit for producing a drive and an information signal to produce ordinary tone or tones related to the call number and to provide ordinary visual displays representative of the message, respectively.          A processed signal is produced by the processing unit to provide extraordinary tones peculiar to a message-absent call, a message-present call, and a repeat call for repeatedly displaying a prior message.  The processed signal also appears to provide extraordinary visual displays unique to the message-absent call.  When the pager receiver has a plurality of preassigned call numbers, the processed signal is produced to provide such extraordinary displays inherent to each of the respective preassigned call numbers.  In addition to the extraordinary displays of the preassigned call number, a plurality of messages are successively stored in a memory in a predetermined order to be successively displayed one by one.          On reception of the repeat call, the predetermined order may be changed to keep the message related to the repeat call from being erasing from the memory even when the memory is full of message.
