Patent EP-0747741-A2 (EP)
Inventor: LOSTRACCO GREGORY
IPC: G02B6/44
Filed: 1996-05-22
Abstract: An optical fiber dispenser (40) includes a bobbin (42), an optical fiber pack (52) overlying the bobbin (42), and a thermal expansion accommodation layer (50) positioned between the bobbin (42) and the optical fiber pack (52). The thermal expansion accommodation layer (50) is made of a material, such as a silicone elastomer, that is readily deformable to accommodate the different longitudinal coefficients of thermal expansion of the bobbin (42) and the optical fiber pack (52). The thermal expansion accommodation layer (50) has a thickness, typically more than about 1/8 inch for a conventional bobbin size, sufficient to reduce any thermal stresses produced by the different longitudinal coefficients of thermal expansion to less than the failure strength of the optical fiber pack (52).

Abstract: A low cost dry polymer processing system has a housing (103) containing submersible pump with a weir (120) mounted on top of the housing and over an impeller chamber (132) in the housing. The weir is a combination of a sleeve (132) and a coaxial funnel (122) with a top edge of the funnel that is level with respect to gravity to the extent that an inside wall of the funnel is wetted with an unbroken sheet of liquid. An electrolyte liquid rising in the sleeve overflows the top edge of the funnel in order to form a liquid sheet or curtain uniformly covering the inside wall of the funnel. The amount of liquid is limited so that the impeller is not hydraulically locked. Dry polymer is dropped through the funnel and into the eye (149) of the impeller enclosed within the chamber which is drained via a port (102) in the bottom of the pump housing. Fresh electrolyte is introduced into the housing at a level which is under the impeller. Thereafter, the mixture of the electrolyte and polymer is drained from the impeller compartment via the port. Before the mixture is completely discharged from the housing, another supply of fresh electrolyte is introduced into the draining mixture.

Abstract: Doctor blade (1) has a compliant lamination (4) having a resin film backing layer (4a) and conductive layer (4b) of abrasive silicon carbide particles and conductive carbon black in a resin binder. The compliant lamination is supported on an aluminum bar (2), having a downwardly extending wall (2b). In use the lamination is bent under the support bar at the end of the wall, a direct turn which avoids a wedge configuration where the lamination contacts the developer roller (7). The conductive layer remains conductive as it wears during use and the avoidance of the wedge prevents a build-up of toner at the nip during use, both of which make possible long effective useful operation of the doctor blade.

Abstract: An antenna assembly comprises an elongate antenna element (11) mounted in a support (5) and movable between a retracted position (see Figure 2) and an extended position (see Figure 1). A helical antenna element (12) is carried at one end of the elongate element. The support (5) comprises a pair of concentric conductors (9,10) which provide a coaxial feed to the antenna elements (11, 12). Suitably the support (5) comprises a dielectric tube (6) having respective conductive portions (9,10) provided on the inner and outer faces thereof. The elongate antenna element is slidably mounted within the central conductor (9). In the retracted position both ends of the elongate antenna element are electrically connected to the central conductor (9). The elongate antenna element is thus rendered inactive as a radiating element and essentially becomes part of the central coaxial feed coupled directly to the helical antenna element. The invention provides a compact and convenient dual antenna arrangement ideally suited for use in a portable cellular radio telephone.

Abstract: A communication terminal device (1) receives an image signal
from a remote facsimile machine. The remote facsimile machine
is adapted to send information (172) about the remote facsimile
machine before the communication terminal device (1) accepts the
image signal. The communication terminal device (1) has a memory

terminal device (1) has already stored information about a
plurality of remote facsimile machines in the memory (17). The
encoder encodes the image signal prior to printing when the
information about the remote facsimile machine sent from the
remote facsimile machine coincides with one of the information
stored in the memory (17). The printer (23) then prints the
encoded image signal on a recording sheet (P).

Abstract: A fabrication method of a solid electrolytic
capacitor is provided, which decreases the necessary
repetition number of adhesion steps of an oxidizing agent and
a monomer of an electrically-conductive polymer to a
dielectric of the capacitor while keeping the capacitance
incidence rate at a satisfactorily high level. A capacitor
body with an oxide layer is first immersed into an oxidizer
solution at a room temperature under an atmospheric pressure.
The oxidizer solution has a viscosity ranging from 100 to 500
cp at room temperature under the atmospheric pressure. Then,
the oxidizer solution adhered to the oxide layer is dried to
remove a solvent of the adhered solution and to leave the
oxidizing agent on the oxide layer. The oxidizing agent left
on the oxide layer is in solid phase at room temperature
under the atmospheric pressure. The capacitor body with the
oxide layer is immersed into a monomer of an electrically-conductive
polymer. The monomer of the electrically-conductive
polymer adhered to the oxide layer is polymerized
by the oxidizer left on the oxide layer, thereby forming a
layer of the electrically-conductive polymer on the oxide
layer. These steps are repeated until a desired thickness of
the polymer layer is accomplished.
