IPC: G02F1/33
Filed: 1997-09-06
Abstract: The optical system (20) includes an acoustooptic device (23) with a drive electrode (24), an acoustic transducer (18), and a transparent optical medium (19) with an aperture (17). A radio-frequency (RF) drive power generator (28) supplies RF drive power at a drive carrier frequency. An RF modulator (25) is connected to the RF drive power generator and a modulating signal source (26). The RF modulator supplies modulated RF drive power modulated with the modulating signal. An RF power compensator supplies RF compensating power at frequencies different from the drive carrier frequency. The RF compensating power complements the modulated RF drive power. The modulated RF drive power and the RF compensating power are combined. A driver is connected to the combiner and the drive electrode for powering the acoustooptic device with the combination of the modulated RF drive power and the RF compensating power such that the spatial thermal energy distribution inside the acoustooptic device remains constant.

Abstract: A process for etching shallow trenches in single crystal
silicon is described. The process etchant comprises
HBr/Cl 2 /O 2 /He. The process can be used with various mask  24 
schemes including, for example, photoresists, oxide hardmasks and
nitride hardmasks. The process forms shallow trenches  32 
typically having a width of from about 0.25 microns to about 1
micron, and a depth of from about 0.3 microns to about 1 micron.
The shallow trenches  32  have rounded bottom corners  38 , smooth
and continuous sidewalls  34  and substantially flat and clean
bottoms  36 . For a given trench width, the profile angle is
substantially uniform across the single crystal silicon. The
trench depth is substantially uniform across the silicon also.
In addition, the profile angle is substantially independent of
the trench depth. The process can comprise one or two etch steps
for etching the single crystal silicon. The two-step etch
process forms shallow trenches having varying profile angles with
respect to the trench depth.

Abstract: A sipe (22) formed in a block is structured, in a depthwise
direction of the sipe, by a narrow groove portion (26) formed at a
ground-contact surface side of the sipe and a wide groove
portion (30) formed at a bottom portion side of the sipe and wider
than the narrow wide portion. A portion connecting the
narrow groove portion (26) and the wide groove portion (30) is inclined
along a longitudinal direction of the sipe. When a pneumatic
tire having a tread surface on which such blocks are formed is
worn, wear proceeds as follows. At an initial stage of wear
during which draining performance of main grooves is
excellent, only the narrow groove portion is exposed so that
noise is suppressed. At an intermediate stage of wear during
which draining performance of the main grooves deteriorates,
the wide groove portion is gradually exposed, and the draining
performance of the sipe improves to compensate for
deterioration of the draining performance of the main grooves.
At a final stage of wear, only the wide groove portion remains,
and because a depth of the sipe is small, noise is suppressed.
In this way, noise can be suppressed until the final stage of
wear of the tire, and at the same time, deterioration in wet
performance of the tire can be suppressed.

Abstract: A surgical instrument assembly for excising a targeted tissue mass to be biopsied from adjacent
bodily tissue of a surgical patient is disclosed. The assembly has a tissue biopsy device and an
expandable sleeve (11) for receiving the tissue biopsy device. The biopsy device has a penetrating
member affixed to a distal end of an elongated tube to facilitate insertion of the tube adjacent the
targeted tissue mass. It also has a tissue receiving chamber at the distal end of the tube for
receiving the mass and a tissue cutter movable relative to the penetrating member from first to
second positions for excising the targeted tissue mass. The expandable sleeve provides an access
portal to the targeted tissue mass. It is expandable from a first original diameter to a second
expanded diameter in response to insertion of the tissue biopsy device where at least a portion of
the device has a device diameter corresponding to the second expanded diameter. When the tissue
biopsy device is inserted through the sleeve, and the sleeve expands, the surrounding tissue is
dilated. The dilation of tissue is less traumatic to the patient than incisional length which matches
the diameter of the penetrating member of the biopsy device.

rotational velocity on the occasion of starting of the

voltage after the electric motor (4) is started by the determined
drive voltage until the detected rotational velocity reaches
the second rotational velocity. Therefore, an unnecessary
inrush current is not generated in the electric motor (4), and

Abstract: A cooling device for halogen lamps in microwave ovens is
disclosed. In the cooling device, two halogen lamps,
installed on the top wall of the cavity, radiate light waves
into a cavity. A cooling fan assembly, provided at a position
around the halogen lamps, generates a cooling air current for
the lamps. An air guide duct guides the cooling air current
so as to allow the air current to flow from the cooling fan
assembly into the atmosphere while cooling the lamps. An
exhaust fan is provided within the air outlet port of the air
guide duct. The exhaust fan increases the flowing rate of the
air current at the air outlet port, which is bent at a right
angle. Due to the exhaust fan, the cooling device of this
invention more effectively cools the halogen lamps and allows
the cooling air current to be more smoothly discharged from
the duct into the atmosphere regardless of the bent shape of
the air outlet port.
