Patent EP-0887955-A2 (EP)
Inventor: WALKER KENNETH LEE
IPC: H04B10/29
Filed: 1998-06-17
Abstract: In an optically amplified multi-wavelength optical fiber communication system
(e.g., 80), deleterious effects due to channel addition/removal can be reduced or avoided
if the optical amplifiers (80) are "overpumped", that is to say, the system is selected such
that at least 70%, preferably 90% or more, of the pump power that is introduced into the
amplifier fiber is unabsorbed in the amplifier fiber.

Abstract: A drill pipe with cold upset ends. The drill pipe includes an elongate
tubular portion with a pin joint on one end and a box joint on the other end. Each of the
ends of the tubular portion is expanded using a cold upsetting process to provide a
transitional portion and a joint receiving portion. The ends of the tubular portion have an
inner and outer diameter which is greater than the inner and outer diameter of the tubular
portion. The wall thickness of the tubular portion is substantially the same throughout its
entire length, including the transitional portions and the joint receiving portions. A drill
pipe made in accordance with this invention is durable and less costly to manufacture. 
     The cold upsetting method by which the drill pipe is made utilizes no
external heat. An internal mandrel is first inserted hydraulically into the ends of a tubular
steel shaft to enlarge the ends. Then, an external "wipe over" die is applied to conform
the wall of the ends being expanded to the shape of the internal mandrel. The pipe thus
produced has a substantially uniform wall thickness.

Abstract: A ribbon cassette which allows a precise recording
operation to be achieved as a result of stably running an
ink ribbon by preventing tilting or rattling of cores caused
by tension produced in the ink ribbon during ink ribbon
winding in order to stably rotate the cores; and a pancake
which allows stable supply of ink ribbon by rotation of the
cores. In the pancake, the cores have shaft-inserting holes,
for inserting therein the supporting shafts which protrude
beyond the carriage, formed in the central portion thereof,
and annular grooves for fitting thereto driving power
transmitting portions for transmitting rotational driving
power of a take-up mechanism. The driving power
transmitting portions are formed so as to protrude at the
outer peripheral side of the corresponding supporting shafts.

Abstract: A SCSI bus extender apparatus coupling a main SCSI bus to a auxiliary SCSI
bus includes a mechanism for detecting and processing SELECTION and
RESELECTION signals transmitted between the two buses to accommodate
target devices on the auxiliary bus which support tagged queuing in accordance
with the SCSI protocol. The invention contemplates reserving an address on
the auxiliary bus for each initiator on the main bus and performing the
appropriate address conversions to enable target devices to properly identify
the correct initiator device during a RESELECTION phase.

Abstract: Multi-port valve assemblies (10) with, typically, two-piece
housings (14,18) are disclosed. Particularly useful in connection with
swimming pools and associated water pumps, the assemblies avoid
reliance on an elongated handle to effect rotation of the
internal structure of the valve. Instead, the assemblies utilize
a knob (98)--which users need not lift--coupled to a post (50) in which an
elongated slot is formed. Doing so avoids breakage problems
associated with use of elongated handles while reducing wear of
internal seals. Each valve assembly additionally may include a
cam (154) having non-semicircular, asymmetrically-shaped recesses (158) into
which followers (170A-B) attached to a shaft (142) passing through the elongated
slot are received.

provided. The method includes a step of setting a time window
for making a decision based upon a predetermined threshold
level, the time window having a time period corresponding to a
transmission data rate in the digital communication system, a
step of detecting a time duration positioned within the time
window, a level of a received signal being higher than the
predetermined threshold level during the time duration, a step
of assuming a substantially middle point of the time duration
as an optimum decision point of the received signal, and a step
of updating the time window so that the updated time window has
its center at a position of the assumed optimum decision point.

Abstract: An apparatus and method is disclosed for bonding a nozzle plate to the
front nozzle face of a printhead. A bonding station includes a heated printhead
holder in opposed relationship to a nozzle plate holder with a curved lower surface.
A nozzle plate having a row of nozzle holes and alignment apertures are formed by

and the nozzle plate is aligned with pins on the curved nozzle plate holder surface.
Both the printhead holder and nozzle plate holder are adjustable in directions
perpendicular to the nozzle array on the printhead face and also rotationally. The
adjustment insures that the nozzle plate, with adhesive applied to the bottom
surface, makes initial tangential contact at the center of the nozzle array, resulting
in accurate alignment of the nozzle plate holes with the nozzle array in the
printhead face.

a logic circuit for outputting the exclusive-OR data of

generator which generates the clock signal, (3) an
erroneous-synchronization phase detector for detecting
whether the phase difference between the data signal and
the clock signal resides within a range of phases for
which there is a possibility of erroneous
synchronization, and (4) an output fixing unit which
holds the phase-difference signal at a fixed value if
the phase difference resides within the above-mentioned
range of phases, thereby it is possible to eliminate
erroneous synchronization in which the clock generator
is locked to a phase other than a target phase.
