Granted: 1992-06-02
Abstract: EXPLOSIVE DETECTION SYSTEM                    Abstract of the Disclosure A system for detecting the presence of explosives contained in an object under observation, including a cavity structure for receiving the object and a radiation source for producing'thermal neutrons directed to the object under observation.  Gamma rays are produced to represent the presence of explosives and as an example the concentration of nitrogen contained in the object.  Inorganic scintillators are located within the cavity structure to detect the gamma rays and produce an output signal representative of the presence and concentration of the nitrogen and/or other elements contained in the object.  The inorganic scintillators are formed as a ring around the cavity structure to detect the nitrogen and/or other elements within at least one particular plane passing through the object.  The object under observation is moved through the cavity structure to detect the nitrogen in successive planes to build up a three dimensional profile of explosives concentration.                        * * * * * * * * *

Title: Adhesive tape for bonding chips thereon
Inventor: NISHIGUCHI MASANORI
IPC: H01L21/52
Filed: 1988-07-08
Granted: 1993-12-14
Abstract: Abstract:    An adhesive tape for bonding a plurality of chips on it is employed in a chip mounting apparatus in which light is applied to one of the chips bonded on the adhesive tape to detect the position of the chip.  The adhesive tape consists of at least three layers: a base layer; a film laminated on at least one surface of the base layer and having a reflectance with respect to light different from that of the chip; and an adhesive layer laminated on either one of the base layer and the film to bond the chip on it.  The film is, for example, of an anti-reflection film, a light diffusion film, a light reflection film or a light scattering film.  The result is an improved optical contrast between the chip and its supporting member and hence improved positioning recognition.

Title: Micr rejects analysis and management information system
Inventor: SPENCE JAMES S
Filed: 1988-08-10
Granted: 1992-08-11
Abstract: ABSTRACT      An interactive and menu driven microcomputer-based system is disclosed which provides financial institution management and quality control personnel with a powerful tool to help manage and control MICR encoded document rejects to reduce the rate of such rejects to a minimum.  The reject analysis system's dedicated microcomputer is linked to a bank's mainframe computer either directly or indirectly by utilizing a mainframe generated item processing magnetic tape file.  The microcomputer-based system may, for example, include a PC having a keyboard and a CRT display, a tape drive, a hard disk, an extended RAM memory, and a printer for generating advisory letters and other hard copy documents.  The microcomputer-based system also includes a MICR reader and analyzer which permits rejected checks to be analyzed for their MICR quality. The system displays a daily summary report showing the total document items processed, the number of rejected items, as well as the rejected percentage. The summary display generically identifies rejected item sources and pinpoints those areas which require immediate attention.  The system also interactively generates a series of display screens including a preprinted rejects report that identifies by account number, the accounts generating the highest number of rejected checks.  In this fashion, the bank is able to quickly isolate those accounts having the most significant impact on its rejected items related operating expense.

Granted: 1993-08-10
Abstract: Abstract of the Disclosure A plasma arc cutting torch, particularly one operating in the 0-200 ampere range, has a shield mounted at its lower end adjacent a workpiece to block splattered molten metal from reaching a nozzle of the torch,  The shield is electrically insulated, preferably by mounting it on an insulating ring that is itself secured on a cap screwed onto the torch body.  A secondary gas flow through the torch passes through the space between the nozzle and the shield to provide cooling.  Bleed ports in the shield allow an enhanced flow rate with the remaining flow being at a rate, in conjunction with the size of an exit orifice in the shield, to stabilize the plasma arc.  Canted ports in the secondary gas flow path produce a swirling of the gas flow which enhances the quality, of the cut.   1853m

Granted: 1993-12-07
Abstract: ABSTRACT        Apparatus for analysing particles in which the particles traverse a sensing zone one at a time.  A first detector measures variations in the conductivity of the fluid caused by the presence of a particle in the sensing zone.  A laser irradiates the sensing zone and a second detector is provided responsive to light scattered by particles in the sensing zone.  Additional detectors are provided responsive to fluorescence from the particles. The signals from each of the detector means are digitized and stored and then compared.  The differences in successive waveforms from each detector indicate the presence of abnormal particles.          Waveform shape is also used as an indication of the shape of the particles.
