Title: Marking of mold inserts to produce marked contact lenses
Inventor: WILLIAMS WAYNER E
IPC: G02C7/04
Filed: 1996-09-27
Abstract: A method for producing visible marks in molded contact lenses, particularly soft hydrogel contact lenses, by placing a recessed mark configuration in a metal insert. The metal insert is subsequently used to produce injection molding frames, which are then subsequently used in the molding of the final contact lenses. The recessed mark configuration is at least approximately 10 microns deep, has a Volume Index, which is the ratio of the quantity volume below a reference surface minus the volume above the reference surface over the volume below the reference surface, of at least approximately 0.9. The recessed mark configuration also preferably has a ratio of surface roughness (RMS or Ra) to a peak-to-valley (PV) measurement, RMS/PV or of Ra/PV, of greater than approximately 0.15. The recessed mark configuration in the metal insert is subsequently transferred as a raised portion to the injection molded frames, and is then subsequently transferred as a visible recessed mark in contact lenses molded in the frames prepared using the inserts. The ratio of the surface roughness (RMS or Ra) to the height (H), wherein H is the distance between two reference lines in a profile of the mark, RMS/H or Ra/H, is at least approximately 1.5. A preferred method of imparting the recessed configuration to the insert is by Electric Discharge Machining (EDM). The dimensions of the several parameters can be verified by using a noncontact scanning white light interferometer.

Abstract: The present invention provides a hydraulic test system,
by which it is possible to select a proper position and to
select a reliable measurement interval corresponding to said
position, to obtain information for preventing retention or
leaving of the equipment in the borehole, and to observe the
conditions in front and lateral directions by a single BTV
at the same time and at wide angle of view without adjusting
focal point. On the tip of a measurement pipe to be
inserted into a borehole, a waterproofing cylinder with a
transparent window for observing in front and lateral
directions is mounted, and there are provided illumination
units for illuminating in front direction and side walls and
a borehole television set equipped with a lens system in
said cylinder, which forms a virtual image of an object in
front direction and a reflected virtual image of an object
in lateral direction on almost the same plane.

Abstract: A method for forming an oxygen-impervious barrier on
the oxide collar of a trench capacitor in a DRAM cell. The
process consists of etching a shallow trench (33) into the oxide
collar which surrounds the polysilicon trench fill (35) and
isolating it from the single crystal semiconducting
substrate material (30) of the DRAM cell to a depth which is at
least equal to or larger than the width of the oxide
collar. A nitride layer (40) with a thickness equal to or
thicker than half of the width of the oxide collar is then
deposited on the top surface of the freshly excavated oxide
collar such that the aforementioned trench is completely
filled with this nitride layer, and the entire surfaces of
the substrate and polysilicon trench fill are completely
covered. The newly formed nitride layer is then
selectively overetched in order to completely remove it
from the substrate and polysilicon trench fill surfaces,
while still maintaining a sufficient thickness of this
layer disposed on the oxide collar sufficient to prevent
oxygen diffusion into the oxide collar. Alternatively, the
nitride layer may be deposited as a thin layer sandwiched
between the original oxide collar and an additional
thermally deposited oxide layer.

Abstract: Disclosed is a treatment accessory (100) for an endoscope. A
treatment unit, for example, a grasping unit (5) is connected at
a distal end of a manipulation wire (33) that is connected to a
first manipulation member (20). Surrounding the manipulation
wire (33), an inner tube (32) is slidably provided. A proximal end of
the inner tube (32) is connected to a proximal end of a second
manipulation member (10). Further, an outer tube (31) is provide to

proximal end of the outer tube (31) is connected to the first
manipulation member (20) so that the positional relationship
between the manipulation wire (33) and the outer tube (31) along the
axis is fixed. By moving the first and second manipulation
members (20,10) to approach, the grasping unit (5) is closed as the
inner tube (32) slides to cover a part of the grasping unit (5),
while when the first and second manipulation members (20,10) are
apart from each other, the grasping unit (5) opens by
resilience.

Abstract: A system for accessing a telephone system (101) in which a set of user stations (102) are matched with a set of base stations (104) for connection to a telephone network (103). Each user station comprises a spread-spectrum transmitter (109) or receiver (108) and is capable of dynamic connection to selected base stations (104). User stations may use CDMA, FDMA, TDMA or other multiple-access techniques to obtain one or more clear communication paths to base stations. Base stations are coupled to each other by means of a private exchange telephone system or other small business telephone system (such as PBX, Centrex, or key type system) so as to couple user stations in calls outside the telephone network. User stations may also be coupled directly or indirectly to the telephone network on their own or by another access path, such as narrowband or spread-spectrum cellular telephone circuits.

Abstract: Fuel injection valves (1) of the engine (10) are
connected to the common rail (3). The high pressure fuel
pump (5) supplies pressurized fuel to the common
rail (3). The electronic control unit (ECU) (20)
determines whether one or more of the fuel injection
valves has failed. When one or more of the fuel
injection valves is determined as having failed, the ECU
stops the high pressure fuel pump and injects fuel from
all of the fuel injection valves including the fuel
injection valve determined as being failed. Since the
fuel remained in the common rail is expelled from the
common rail through, not only the failed fuel injection
valve, but also other fuel injection valves, the common
rail is depressurized in a short time and, thereby, the
abnormal fuel injection from the failed fuel injection
valve stops in a short time.

Abstract: A light beam emitted by a surface illuminant (11)
reaches the surface of a transparent base layer (15) of
a recess/projection detection optical element (13). A
light beam emitted almost vertically is emitted to an
air layer. A light beam incident on the transparent
base layer at an angle larger than a total reflection
angle returns to a two-dimensional photosensor (12) at
a portion contacting the air layer, but scatters in a
transparent particle at a portion contacting the
transparent particle (16). When a finger (31) is
brought into contact with a scattering reflection layer
(14), the scattering reflection state does not change
in an area corresponding to a valley (31a) of a
fingertip. As indicated by an arrow C, an amount of
reflected light beam is large. In an area
corresponding to a ridge (31b) of the fingertip, the
light beam scattered by the transparent particle is
absorbed. The amount of reflected light beam is small,
as indicated by an arrow D. An image having bright and
dark portions optically emphasized in correspondence
with the valley and ridge of the fingertip of the
finger can be obtained.

Abstract: An image development method and apparatus in which
image-wise charging of a toner layer (58) is accomplished
by induced air breakdown electrical discharge such that
free mobile ions are introduced in the vicinity of an

mobile ions to flow in an image-wise ion stream
corresponding to the latent image, which, in turn, leads to
image-wise charging of the toner layer (58), such that the
toner layer (58) itself becomes the latent image carrier.
The latent image carrying toner layer is subsequently
developed and transferred to a copy substrate to produce an
output document (70).
