Abstract: Nonmetallic materials (18, 28) are welded without solder or adhesive by a
laser (202) and preferably fiber optics (204) that direct laser light (220)
through one of the materials (18) to create a seam weld. Through use of
fiber optics the beam is optimally (Fig. 11) converted to heat, avoiding weld
flaws due to underheating and material damage due to overheating.
Welding is rapid and reproducible even for the smallest of contact
geometries, achieving for example strong solderless gold-to-gold compression
laser welding of a silicon substrate (28) to a polymeric ( e. g.  polyimide) flex
circuit tape (18), without tape damage. The bond can be between a straight
gold-bond line (210, Figs. 20-22[C]), or complex weld seam pattern (210,
Figs. 17-19[C]), on the tape and a mating gold bond line or pattern (Figs.
17-22[A]) 208 on a semiconductor chip (28). In an inkjet printhead the
result is to avoid delamination and nozzle skewing, associated in other
methods with adhesive curing. Reduced skew provides less dot-placement
error and thus better print quality. Better head configuration facilitates
fixing a nozzle member to the substrate, and increasing nozzle area stiffness,
nozzle camber angle and directionality, and substrate-to-tape bond
strength-reducing deformation and so consistently raising ink refill speeds,
and reducing ink trajectory errors and delamination. In particular
embodiments, increased tolerance to aggressive solvents in inks, and more
consistent chamber geometry, result in better drop-volume control, better
pen quality, repeatability and reliability; and cutting down of process steps,
processing time, cost, and in-process handling. These in turn provide ease
of assembly, higher yields and reliability, ease of nozzle serviceability, and
overall material and manufacturing cost reduction.

Abstract: A timing recovery system for a digital signal receiver receives a signal, representing successive symbols, from a transmitter. The symbols are subject to exhibiting multiple symbol rates. The system derives a sample enable signal from the received input signal and employs a single, fixed frequency oscillator. A source (10) of samples representing the received signal are sampled at a fixed frequency. An interpolator (12) is coupled to the sample source and is responsive to a control signal. The interpolator produces samples taken at times synchronized to the successive symbols from the transmitter. A phase error detector (16) is coupled to the interpolator, detects a phase error between the sample times of the transmitter synchronized samples produced by the interpolator and times of the successive transmitter symbols, and supplies a phase error signal. The phase error signal is coupled to one input terminal of a summer (32) and a source (31) of a nominal delay signal is coupled to the other. A numerically controlled delay (34-46) produces the control signal for the interpolator in response to the signal from the summer. An output signal from the interpolator is filtered by a fixed, non-adaptive pulse-shaping filter (14).

Abstract: A current resonance power supply circuit resonates the primary winding L61
of the switching transformer 64 and the current resonance capacitor C2I by turning

out-of-resonance phenomenon hardly occurs upon a sharp drop of the AC power
voltage or a quick increase of the load.

Abstract: The system includes a control arrangement for detecting at least one sequence of numbers and for outputting the recognised numbers of at least one number sequence. When there is at least one falsely detected number in a first number sequence the control arrangement compares a spoken second number sequence with the first number sequence. The control arrangement determines the related numbers of a first sequence with the closest coincidence to the numbers of the second sequence if the number of numbers in the second sequence is smaller than in the first sequence. The control arrangement replaces the identified part of the first sequence with the non-coinciding numbers of the second sequence.

Abstract: A system for programming arrays of floating gate memory cells is provided that
reduces programming current requirements, and reduces wordline and bitline stress
during programming. A word-to-be-programmed into a floating gate memory
array is divided into a plurality of smaller subwords. Only one subword is
programmed at a time, thereby reducing programming current requirements.
Additionally, subwords which are successfully programmed are not
reprogrammed even if bits in other subwords do not program properly. This
creates less wordline stress than previous systems which program an entire
word at once, thereby requiring subwords which program successfully to be
reprogrammed along with subwords which fail to program. Finally, within
each subword only those bits which failed to program are reprogrammed,
thereby reducing bitline stress during reprogramming for those bits which were
successfully programmed.

preceding the discharge of the first droplet from the
discharge opening at a first discharge speed V 1 , the

opening at a second discharge speed v 2  smaller than the
first discharge speed, and before each of the liquid

a range that does not render any hinderance practically
even if discharge speeds may fluctuate, hence obtaining

Abstract: The invention provides an elongate turning vane for altering the direction of air
flow in a duct, such as a wind tunnel, where the vane includes means for
attenuating sound propagation past the vanes. The vane has extreme ends
mounted to opposing sides of the duct, a longitudinal axis and an
aerodynamically efficient profile. The vane comprises a rigid core having air
permeable upper and lower surfaces, preferably a welded assembly of two
perforated sheet metal plates with transverse profile plates, with vent holes, to
provide the appropriate shape and venting. Two sound attenuating panels have
interior surfaces bonded to the upper and lower core surfaces of the core, and
exterior surfaces defining suction and pressure surfaces of the vane. Vent means
provide for passage of air axially within the core between the duct and the core
surfaces. Venting is required to balance the air pressure on both sides of the
sound attenuating panels to prevent distortion of the panels bonded to the core.
Rippling and other distortions detrimentally effect the aerodynamic efficiency
of the vane. To preserve the aerodynamic shape of the vane and structural
integrity, a rigid nose fairing is mounted to a leading edge of the core, and a rigid
tail fairing mounted to a trailing edge of the core. A protective layer on the
exterior surfaces of the sound attenuating panels provides mechanical protection
from air borne debris and contaminants. The protective layer is preferably a
matte urethane film that is impervious to air for protection of the panels and is
pervious to sound propagation between the duct and the sound attenuating panels
to preserve the sound attenuating properties of the panels.
