Granted: 1994-05-03
Abstract: Abstract of the Disclosure:     In an information processing device for use in indicating an operation number of floating point operation elements, such as either vector elements of each vector instruction or scalar instructions, the floating point operation elements are successively counted by an adder and a register to produce operation number signals representative of results of the counting.  The operation number signals are periodically read out of the register as preceding and following operation number signals at preceding and following ones of periodical signals sent as a time signal from a digital timer, respectively, and are held in registers.          A subtracter subtracts the preceding operation number from the following operation number to calculate a difference signal between the preceding and the following operation numbers and to provide the operation number per unit time.  The difference signal is visually displayed on a display unit in real time.          Alternatively, each of the preceding and the following operation number signals may be memorized in a scalar register together with the time signal.

Granted: 1994-02-15
Abstract: Abstract of the Disclosure This invention is directed toward reducing substantially the loss incurred when two optical fibers of different mode diameters are coupled together. In this invention, the coupling of one fiber to that of another where the fibers are of different mode diameters is not with a tapered fusion, core-to-core splice, but with an evanescent field fiber coupler. Briefly, to achieve amplification of a weak optical signal, an amplifying fiber is inserted into the system at one or a plurality oflocations. More specifically, at a desired location, the transmission fiber is severed to provide two sections and the severed sections are transversely coupled to theamplifying fiber. The weak signal from the first section of the transmission fiber is coupled into the amplifying fiber via a first evanescent field type of fiber coupler, and the amplified signal is coupled from the amplifying fiber to the second section of the transmission fiber via a second evanescent field type of fiber coupler. The first evanescent field type of fiber coupler is designed w couple substantially all of the signal energy from the first section of the transmission fiber to the amplifying fiber and to couple substantially none of the laser diode pump signal or energy from the amplifying fiber to the transmission fiber. The second evanescent field type of fiber coupler is designed to couple substantially all of the signal energy in the amplifying fiber to the transmitting fiber and substantially no laser diode pump energy is transferred from the amplifying fiber to the transmission fiber. Either or both cut ends of the transmission fiber can be coupled to monitor devices to detect and determine the value of the signal being coupled into an/or out of the amplifyingfiber w control, for example, the gain of the amplifying fiber.

Title: Telephone communication system
Inventor: JONES SCOTT
IPC: H04M3/50
Filed: 1990-08-09
Granted: 1996-03-19
Abstract: The present invention provides a distributed architecture that includes multiple voice processing units.  A voice processing unit is designated as a home voice processing unit for a subscriber's messages.  An incoming call or access by a subscriber from a central office is preferentially switched to the home VPU by a digital switching system under the control of a master control unit.  If the master control unit determines that all lines to the home voice processing unit are busy or the voice processing unit is otherwise unavailable, the master control unit causes the digital switching system to switch the call to another or remote voice processing unit.  The remote voice processing unit then handles the call by either locally storing a message or retrieving a message from the home voice processing unit storage over an internal message bus.  If a message is stored remotely and the home voice processing unit is processing the subscriber request, the home voice processing unit can access the remote message over an internal message bus or the master control unit can switch the call routing through the digital switching system to the remote voice processing unit for processing of the remote message and return the digital switching system routing to the home voice processing unit when finished with the remote message.  Each voice processing unit stores both remote and home messages locally on local disc storage units.  The master control unit stores subscriber related information such as the home voice processing unit for each subscriber and the location of each message for that subscriber.          Communication between the master control unit and the voice processing units is over an internal network.  A hot standby master control unit is provided to take control of the system in the event that the primary master control unit fails.

Title: Film ghost removal in electrographic plotters by voltage bias of the plotter fountain or film edge-strip
Inventor: HANSEN LORIN K
IPC: G03G15/05
Filed: 1990-11-30
Granted: 1996-01-09
Abstract: A preferred embodiment of the present invention is directed to a removal of a ghost image created during a processing of a film laminate medium by an electrographic plotter.  A recording of an image on the film medium induces a ghosting potential over a developing station.  The ghosting potential causes a spurious image to be developed by the developing station.          The recorded image is created by depositing a charge on a dielectric layer of the film.  A relationship exists between the deposited charge and the ghosting potential.  By use of information known to the system, the ghosting potential may be estimated and reduced.  A preferred method estimates the magnitude of the ghosting potential by use of the relationship between deposited charge and ghosting potential.  A counteracting potential is applied to the system to reduce the ghosting potential over the developing station.  The reduction of the ghosting potential substantially removes the ghost image created during the processing of the film laminate.

Abstract: Disclosed is a multi-point welding method capable of certainly welding an object having a number of points to be welded for a short time.  First, an approximately cylindrical base body is formed by alternately laminating a flat sheet and a corrugated sheet and then winding them in a spiral shape.  In this case, there exist a number of contact points of the flat sheet to the corrugated sheet, that is, points to be welded.          Next, there is provided an electrode apart from one end surface of the base body by a specified interval and facing to the end surface.  After that, by intermittently applying a current across the electrode and the one end surface of the base body thereby intermittently generating electric discharges between the electrode and the one end surface of the base body, to thus fuse and weld the points to be welded of the flat sheet to the corrugated sheet.  With this arrangement, it is possible to certainly weld multi-points to be welded for a short time by only intermittently applying electric discharges.
