Patent EP-0846966-A3 (EP)
Inventor: YONEDA ISAO
IPC: G02B6/42
Filed: 1997-12-04
Abstract: The invention provides an optical waveguide by
which, where a laser device of the surface light
emitting type or a light receiving device of the
surface light receiving type and the optical waveguide
are to be coupled to each other, even if the device is
to be mounted as of the plane mounting type, the
mounting form is not complicated and the production
cost necessary for optical axis adjustment is not
increased. A V-shaped groove is formed on a surface of
a substrate, and light reflecting films for reflecting
light are formed at the opposite ends of the V-shaped
groove while an optical fiber is mounted in the V-shaped
groove. By the construction, light is bent by
the light reflecting films formed on inclined surfaces
of the V-shaped groove. Consequently, in coupling
between the optical fiber and a light emitting or
receiving device of the surface light emitting type or
the surface light receiving type, the optical
semiconductor device can be mounted with a high degree
of accuracy directly on the same substrate just above
any of the light reflecting films with the light
emitting surface or the light receiving surface thereof
directed downwardly.

Abstract: A shielded needle assembly including an elongate needle with a proximal end, a distal
end and a passageway therethrough. The assembly has a needle hub with a proximal end, a
distal end and an outside surface. The proximal end of the needle is fitted and held in an axial
opening through the needle hub at the distal end of the needle hub, with the distal end of the
needle projecting distally axially. The proximal end of the needle hub is configured for
releasable mounting the needle hub on a fluid handling device. The assembly of the invention
has a shield with an open proximal end, a distal end, a sidewall having an elongate opening
extending from the proximal end to the open end. The shield is operative between an open
position, where the needle is exposed for use by passage through the elongate opening, a
closed position, where the shield substantially obstructs access to the needle, and a latched
position, where the shield is substantially prevented from inadvertent movement to the open
position. The shield is attached to the needle hub by a mount with a hinge. The shield is
movable between the open position and the closed position by an off axis pivotal movement
about the hinge, and between the closed position and the latched position by an axial
movement of the shield with respect to the mount.

IPC: C30B31/00

Abstract: Single crystal sapphire  (34)  is conventionally employed for mid-wave IR
windows and domes exposed to high aerodynamic heating environments. Single crystal
sapphire  (34) , however, suffers a loss of compressive strength in the c-axis of 95% on
heating from ambient to 800°C. This loss of compressive strength on heating results in
poor thermal shock resistance. Poor thermal shock resistance jeopardizes the reliability
of the windows  (32)  and domes. The process of the present invention strengthens
sapphire  (34)  and improves its resistance to thermal shock by introducing magnesium
(Mg) ions into the crystal lattice of sapphire  (34)  to form a solid solution. The solid
solution increases the strength of the sapphire  (34) . Additionally, a larger increase in
strength results from converting the Mg into second phase precipitates  (40)  comprising
magnesium aluminate spinel. The formation of the second phase particulates  (40) 
results in precipitation-hardening or precipitation-strengthening due to the volume
change on forming the magnesium aluminate spinel. The second phase particulates  (40) 
comprising magnesium aluminate spinel are held to such a small size that the second
phase particulates  (40)  impart increased fracture strength while not significantly
degrading the IR transmission when compared with untreated sapphire  (34) .
Consequently, precipitation-hardening with magnesium aluminate spinel improves the
compressive strength of sapphire  (34)  while retaining high thermal conductivity and IR
transmission.

Abstract: An exercise bicycle including a frame having a seat and handlebars, a high-inertia
flywheel having a hub at a center of rotation, the flywheel being rotatably
supported on the frame at the hub, and a drive train including a drive sprocket, a crank
arm attached to and extending from the drive sprocket, and a pedal attached to the
crank arm, the drive train being rotatably supported by the frame. The drive train also
includes a slave sprocket fixed to the flywheel at the hub, with the drive and slave
sprockets connected in a direct-drive relationship, the drive train driveable in a forward
and rearward directions to cause the flywheel to rotate. A clutch mechanism is
positioned in engagement with the slave sprocket and the hub to create a frictional
engagement between the sprocket and the hub, and to establish a break-free
force
threshold. When the drive train is actuated in the forward direction, the slave sprocket
and the hub move together, and when the drive train is actuated in the rearward
direction under the influence of a force greater than the break-free force threshold, the
clutch mechanism slips between the slave sprocket and the hub, allowing the slave
sprocket and the flywheel to move independently of one another.

Abstract: A method for fabricating a bit line junction in a DRAM array device which
improves the doping profile in the channel region. The method includes contradoping via
ion implantation through the bit line contact opening (375) made in the device during processing.
This particular doping method increases the concentration of dopants in the channel region (258)
on the bit line side (251) of the array, without a corresponding increase of dopants on the buried
strap side (252). Such a doping profile results in an improvement in the off current behavior of
the device. Depending on the aspect ratio of the contact opening, tilt angles for the ion
implantation are possible and can be adjusted for maximum off current efficiency.

Abstract: A brushless DC motor comprises a rotor (20) and a stator (22) having confronting surfaces. Permanent magnets (M) are provided at one of the confronting surfaces, the magnets being equally angularly spaced around an axis (A-A) of rotation of the rotor such that each magnet occupies part of a respective pole arc (PA) of a first circle (C1) centred on the axis (A-A), the pole arcs each subtending a common pole angle ( alpha ) to the axis. Teeth (Tm) are provided at the other of the confronting surfaces, the teeth being angularly spaced from one another around the axis (A-A) such that each tooth occupies part of a respective tooth arc (TA) of a second circle (C2) centred on the axis, the tooth arcs each subtending a common tooth angle ( beta ) to the axis. Windings (40) are wound around the teeth (Tm) whereby energisation of the windings with electrical currents at respective phases will produce a torque that will rotate the rotor (20). The tooth angle ( beta ) is substantially equal to the pole angle ( alpha ). The teeth (Tm) are arranged in an even number of sets, each set comprising at least one tooth (Tm). A respective further tooth (Ta) is disposed between each such set, each further tooth not having a winding thereon and each further tooth occupying part of a respective further arc of the second circle (C2), the further arcs each subtending to the axis (A-A) a common angle ( gamma ) substantially equal to twice the above-mentioned pole angle ( alpha ) divided by the number of phases. <IMAGE>

Abstract: A wafer-scale assembly apparatus for integrated circuits and a
method for forming the wafer-scale assembly are disclosed. A
semiconductor wafer including a plurality of circuits is
provided with a plurality of metal contact pads as electrical
entry and exit ports. A first wafer-scale patterned polymer
film carrying solder balls for each of the contact pads on the
wafer is positioned opposite the wafer, and the wafer and the
film are aligned. The film is brought into contact with the
wafer. Radiant energy in the near infrared spectrum is applied
to the backside of the wafer, heating the wafer uniformly and
rapidly without moving the semiconductor wafer. Thermal energy
is transferred through the wafer to the surface of the wafer and
into the solder balls, which reflow onto the contact pads, while
the thermal stretching of the polymer film is mechanically
compensated. The uniformity of the height of the liquid solder
balls is controlled either by mechanical stoppers or by the
precision linear motion of motors. After cooling, the solder
balls solidify and the first polymer film is removed. The
process is repeated for assembling sequentially a wafer-scale
patterned interposer overlying all of the solder balls and the
wafer and contacting each solder ball with a soldered joint, and
a second wafer-scale patterned film carrying solder balls
contacting the interposer. In each process, the wafer is
heated uniformly and rapidly and without moving it, the
alignment is maintained during heating by mechanically
compensating for the thermal stretching of the polymer film, and
the uniformity of the height of the liquid solder balls is
controlled by mechanical stoppers or position closed-loop linear
actuators. The second film is removed after cooling. Other
embodiments are also disclosed.

Abstract: For braking a disk drive when a power fault occurs, a
circuit (10) produces an output signal (28) indicating that
the motor of the disk drive has slowed at least to a
predetermined rotational speed after the occurrence of the
power fault. Components of the
circuit (10) may be integrated onto the same integrated circuit
as the motor driving circuitry or head retract circuitry.
During the time between the occurrence of the power
fault and the time the disk drive has slowed to the predetermined
rotational speed, the read/write head mechanism
(17) is retracted. A braking circuit then brakes the disk
drive when the output signal (28) indicates that the motor
has slowed at least to the predetermined rotational speed.
The circuit for producing an output signal indicating that
the motor has slowed at least to the predetermined rotational
speed is actuated by the back-emf (14) generated by
the motor falling below a predetermined level.
