Patent EP-0750336-A2 (EP)
Inventor: MAYUZUMI MASANORI
IPC: H01L21/66
Filed: 1996-06-03
Abstract: A silicon wafer is held in an airtight chamber by a silicon wafer holder. The silicon wafer holder is cooled by a cooler. High purity nitric acid is stored in a storage container disposed in the airtight container. The storage container is heated by a heater, thereby producing nitric acid gas. The nitric acid gas is condensed on the surface of the silicon wafer so that a thin film is formed. Thus, the surface of the silicon wafer is rendered hydrophilic. Thereafter, high purity hydrofluoric acid is dropped on high purity nitric acid in the storage container by an acid dropper, thereby producing hydrofluoric acid gas. By introducing the hydrofluoric acid gas into the thin film formed on the surface of the silicon wafer, an etching is performed while maintaining the surface of the silicon wafer in a good condition.

Abstract: A memory interfacing method for a variable-length decoder and a circuit therefor are provided. The memory interfacing circuit (10) includes a read controller (15) for generating a read chip-enable signal and a read address in response to a first request signal output from the variable-length decoder (21), generating a second request signal when the read address reaches a predetermined level, and providing the second request signal to an external memory controller (13) which is connected to an external memory (11), a write controller (17) for generating a write address and a write section signal in response to an accept signal generated by the external memory controller (13) in response to the second request signal, and an internal memory controller (19) which includes an internal memory, for controlling data provided from an external memory (11) to be written according to the write address and the write section signal generated by the write controller (17). Accordingly, the present invention simplifies complex signal processing due to frequent memory access between a variable-length decoder (21) and external memory (11).

Title: Multi-leaf radiation attenuator for radiation therapy with verification system
Inventor: SWERDLOFF STUART
IPC: G21K5/10
Filed: 1994-06-08
Abstract: A radiation therapy apparatus includes a compensator with moving leaves to attenuate a radiation beam and a compensator verification system to determine if the attenuating leaves are moving in accordance with desired position signals. Two radiation intensity monitoring chambers, one chamber on either side of a patient within a radiation beam, produce beam fluence data used by a computer to construct radiation absorption images and to evaluate the functionality of the compensator. The absorption image can be used for radiation dose verification and planning of suitable subsequent therapy sessions. The compensator may include a first plurality of radiation attenuating leaves and a second plurality of radiation attenuating leaves. The first plurality of leaves may be spaced with gaps between adjacent leaves within a radiation beam so that the leaves and the gaps there between divide the radiation beam into rays. The second plurality of leaves may be disposed directly under gaps in the first plurality of leaves so that each ray of beam can be occluded by a leaf in either the first or second plurality. The gaps eliminate interference between leaves; the staggering prevents radiation leakage between leaves. Each leaf, in both groups, may be moved between a first open state on one side of the beam, a closed state within the beam thus occluding one ray of the beam, and a second open state on the other side of the beam. <IMAGE>

Abstract: A method and apparatus provides data transmission between synchronous
systems. One system has a phase locked loop to provide its local clock. The other
system has a fixed clock. Fully synchronous bidirectional communication is achieved
by adjusting the lengths of the delays between the systems, possibly by adjusting the
cable lengths.Deterministic lockstep operation between systems separated by a
significant distance is permitted where the communication delays are large compared
to a single clock cycle of the systems. Practical tolerances on cable length and signal
noise and jitter can be accommodated.

Abstract: A method for encoding digital information to be
transmitted from a first device to a second device, wherein
the digital information is mapped according to a map of n
rows and m columns which define a plurality of cells (n x m)
and wherein each of said cells has a pixel value. The
method is useful for compressing bitmapped images to be
rendered by the simplest of graphics engines. Thus the
method is particularly suited to the transmission of images
to a relatively slow client on which the images are to be
rendered in real time and on which any complex decompression
would be too costly for such rendering. Raw compression
ratios are comparable to those obtained with standard run-length
encoding, but the number of drawing primitive calls
required to render the compressed images directly is
substantially less.

Abstract: The present invention relates to a recording and reproducing
method and apparatus for an optical disk 1 of the phase
transition type that can be overwritten. According to this
invention, the capacity of repeated rewriting of the optical disk
1 is expanded by recording either non-inverted write data 11a
or inverted write data 11b at random. The deterioration due to
the repeated rewriting at a start point and an end point of the
recording is suppressed by recording a synchronizing signal before
the write data and/or dummy data after the write data by varying
the signal mark to space relation
such that thermal stress is less likely to occur. A record end
position can be determined precisely by detecting a stop pulse to
stop recording.

Abstract: A apparatus and method for controlling an

various types of corrections using a relatively large
beam, but oscillating, or dithering, that being to
prevent reinforcing ridges from being formed during
the tissue removal process. Further, various types of
correction, such as hyperopia and astigmatism
correction, are performed using a large beam that is
scanned over the area to be ablated using overlapping
shots. Further, the epithelium in the area to be
treated is removed using an infrared fluorescent dye
to dye the epithelium, and then observing the
fluorescent patterns from the epithelium area to be
removed. Once a certain area is no longer fluorescent
after laser shots, smaller shots are then applied,
selectively removing the epithelium from the remaining
regions. Again, the fluorescence patterns are
observed, and the process is repeated until no
epithelium remains. At this point, all of the
epithelium is removed, and further a map is created of
the initial epithelial thickness at each point in the
area from which the epithelium was removed.

Abstract: A preferably cast zinc housing (4) has a chamber (22) for
receiving a metal stranded cable (6) 1/16 inch in diameter
which is swaged at one end to the housing in the chamber (22).
The housing (4) has a conical bore (32) in communication with the
ambient about the housing via apertures at opposing ends of
the housing. A channel (36) having a depth of about one half the
cable diameter is in the bore surface aligned with the
apertures to form a continuous cable insertion path with
the apertures. A relatively weak coil spring (50) and a pair of
different diameter steel balls (52,54) are in the conical bore (32).
The cable free end is inserted into the path through the
housing with minimal insertion resistance from the balls (52,54)
and spring (50). Withdrawal of the cable wedges the balls (52,54)
uniformly against the cable (6) deforming it and locking the
cable (6) to the housing (4). The balls (52,54) each uniformly stress the
cable (6) to spread the stress of the wedging action. This
reduces stress concentration on the cable (6) at each ball (52,54) so
that the cable (6) fails only at its maximum tensile load.
