Abstract: A method and apparatus applies a constant tension to a film (30) in a wrapping machine having a film roller (20) rotated at a variable rate by a film (30) drawn over it. The rotating film roller (20) drives a hydraulic pump (50) at a variable rate dependent on the rotation rate of the film roller (20). An oil reservoir (60) is coupled to the hydraulic pump (50) with hydraulic circuit (40), so that the hydraulic pump (50) pumps oil through the hydraulic circuit (40) as the film roller (20) drives the hydraulic pump (50). An adjustable constant pressure valve (70) is coupled in the hydraulic circuit (40) and maintains a constant oil pressure in the hydraulic circuit (40), so that the hydraulic pump (50) maintains a constant drag on the film roller (20) independent of the rate at which the film roller (20) drives the hydraulic pump (50), and wherein the constant drag on the film roller (20) applies a constant tension to the film (30) independent of the rate at which the film (30) is drawn over the film roller (20).

Abstract: The manufacturing process is monitored by relating product properties to process data by means of a forecasting model which gives at least one prediction with a confidence limit range. Process data is continually measured and stored and compared with the boundary values for which the model is valid. When process data fall outside the valid range, product properties are measured and recorded. If the measured properties are outside the confidence limits of the predictions of the model. the model is amended accordingly. Also claimed is a corresp. procedure for controlling a process where the model is used to predict the result of a control action.

Abstract: A micromachined pump including a channel formed in a semiconductor substrate by conventional processes such as chemical etching. A number of insulating barriers are established in the substrate parallel to one another and transverse to the channel. The barriers separate a series of electrically conductive strips. An overlying flexible conductive membrane is applied over the channel and conductive strips with an insulating layer separating the conductive strips from the conductive membrane. Application of a sequential voltage to the series of strips pulls the membrane into the channel portion of each successive strip to achieve a pumping action. A particularly desirable arrangement employs a micromachined push-pull dual channel cavity employing two substrates with a single membrane sandwiched between them.

Abstract: A developing device has a development roller for
carrying toner on a surface thereof, a toner supply
roller for supplying the toner to the development
roller, a flat spring which comes into contact with the
development roller, charges the toner to be supplied to
the development roller and applies the toner to the
development roller while regulating the thickness of a
layer of the toner. The flat spring has a plurality of
flat-plate parts including a contact flat-plate part
which comes into contact with the development roller,
and a curved part which connects the flat-plate parts
to each other. In this structure, by arbitrarily
selecting dimensional parameters of the flat spring, it
is possible to easily obtain various flat springs
having different properties. Therefore, for example,
the stress to the toner and the stress to the members
can be easily reduced simultaneously with a design of
the flat spring. Moreover, it is possible to improve
the uniformity of the toner layer thickness in the axis
direction of the development roller and the uniformity
of charging of the toner.

Abstract: In an optical transmission system in which an optical main signal and a monitoring
control optical signal are wavelength-multiplexed and transmitted from a transmitter and
the optical signal is directly amplified by a repeater and transmitted, low frequency pulse
signals which are synchronized with the respective optical main signal and monitoring
control signal are multiplexed with each others, a distance of a transmission section is
specified by a phase difference between the low frequency pulse signals according to a
difference in propagation rate of a transmission line due to a difference of wavelength
between the optical main signal and the monitoring control signal and the optimal
dispersion compensation is made possible even when a required dispersion compensation
is changed due to a change of the transmission line by switching the optical transmission
line to a DCF having an optimal amount of dispersion compensation.

Abstract: An automobile seat backrest includes an adjustable lumbar support assembly for selectively applying pressure to the lower area of a seated occupant's back. The backrest portion has a structural frame and a wire mesh within the frame for supporting a foam cushion. A cover envelopes the frame, wire mesh and cushion. First and second cranks are moveably supported on the wire mesh within the cover of the backrest portion. Cantilever arms extend from the respective first and second cranks to carry corresponding first and second applicator pads. A manual actuator causes the applicator pads to move in a synchronized fashion toward respective extended positions applying outward pressure to the cover. The manual actuator includes a twist knob which controls a worm gear, and a drum having gear teeth that mesh with the worm gear. A conduit extends from the actuator to the first crank, and a core element, slidably disposed within the conduit, interconnects the twist knob and the second crank. The actuator simultaneously applies a tensile force along the core element and a complimentary compressive force along the conduit to move the first and second cranks and to thereby displace the first and second applicator pads in unison against the cover, thus providing variable lumbar support to a seated occupant.

Abstract: Artwork is imparted to plastic discs such as
CDs, CD ROMs, and DVDs (digital video discs) by
exposing a layer of photoresist material on a substrate
to light from an original image of the artwork. The
material of the photoresist layer is exposed to
different depths by different intensity light from
different image regions. Where the image is dark, the
exposure is to relatively shallow, random depths.
Where the image is light, the full thickness of the
photoresist layer is exposed. Development of the
photoresist layer removes the exposed photoresist
material. The surface features of the developed
photoresist layer and any uncovered substrate are
transferred to a member used in forming a surface of
the plastic disc, thereby visibly embossing the image
in the disc.

Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. The users or collaborators in a session are connected by one or more controllers in the server system. When a collaborator creates or joins a session, mobile code is transmitted from the system to the collaborator's computer to create a surrogate thereon, which monitors the collaborator's interaction with a web browser on the computer. The controllers communicate with all the surrogates of the collaborators to coordinate the collaborative browsing effort. When one of the surrogates detects a change by a collaborator of a uniform resource locator (URL), the new URL is communicated through the controllers to the surrogates of all other collaborators in the session. As such, the collaborators are able to move from one URL to another to browse information in a synchronous manner. In addition, the collaborators can interactively communicate with one another in real time through the respective surrogates during the session.
