Patent EP-0833223-A2 (EP)
Inventor: TSUJI MASARU
IPC: G03G15/20
Filed: 1997-08-20
Abstract: A heat-resistant sheet, which has at least one slash
alone formed therein, is provided between a fixing roller
and a pressure member. The heat-resistant sheet, which has
a thickness of 300 µm, is coated with a synthetic resin
material having superior toner-releasing and heat-resisting
properties, or incorporates such a synthetic resin material
inside thereof. Here, a recording material is transported
between the fixing roller and the heat-resistant sheet. As
the surface temperature of the fixing roller rises, the
heat-resistant sheet starts expanding gradually, causing its
surface to be warped. However, unless the temperature of
the fixing roller exceeds a set temperature, the expansion
of the heat-resistant sheet and its surface deflection are
all absorbed by the slash. Therefore, it is possible to keep
an optimal nip width while maintaining a proper applied
pressure of the pressure member, without the necessity of
using a heat-releasing device or increase the thickness of
the heat-resistant sheet. As a result, a superior fixing
operation is available by using the heat-resistant sheet
having the slash alone.

system is utilized to interconnect the carriers (26), and is connected to the carriers (26) in
alignment with the tilt rod (42) so as to minimize skewing. The carriers (26) have pockets (164)
formed therein through which the traverse cord (68) extends so that the traverse cord (68),
which moves the carriers (26) along the tilt rod (42), is secured to a lead carrier (26) closely adjacent
to the tilt rod (42) to, again, minimize skewing. Light blocking rails (240) are also attachable to
the headrail (20) to substantially bridge the gap between the headrail (20) and the top of the
suspended vanes (24) to prevent light from passing therebetween. The tilt rod (42) is keyed to
gears in the carriers (26) to facilitate assembly of the control system (22) with all vanes (24) properly
aligned.

Abstract: There is provided an apparatus for measuring the
characteristics of an optical fiber in which a frequency difference
between first and second coherent light respectively generated by
first and second light sources can be accurately set and wherein
preferable coherent detection can be carried out in accordance with
frequency components of returned light. First coherent light at
a frequency f1 is converted into a pulse light which is output to
the optical fiber to be measured. The characteristics of the
optical fiber are measured by multiplexing returned light from the
optical fiber to be measured and second coherent light at a
frequency f2 and by detecting the multiplexed light. A component
|f1 - f2| is detected from an optical signal obtained by the
multiplexed light and is mixed with a signal at a frequency fr to
decrease the frequency. An electric signal at a voltage level
corresponding to a differential frequency |f1 -f2| - fr included
in the mixed signal is generated, and a predetermined voltage level
is generated which corresponds to a set value for an optical
frequency difference between the first and second coherent light,
The second light source is driven based on the difference between
the two voltage levels to correct the frequency of the second
coherent light.

Abstract: A wireless base station (300) has a transmitter (302) and receiver
(307).Transmission signals are applied to an antenna (305) through a transmit bandpass
filter (304) that is tuned for a transmit band of frequencies. Received signals from the
antenna are applied to the receiver through a receive bandpass filter (306) that is tuned
for a receive band of frequencies. An RF switching array (311) consisting of four RF
switches (S1-S4) interconnects the output of the transmitter and the input of the receiver
such that normal, loopback (self-test), and scanning modes can be performed. In the
normal mode, the antenna is connected to the transmitter and receiver through the
transmit and receive bandpass filters, respectively. The transmit and signal paths are
effectively isolated from each other by three serially-connected open switches. In the
loopback mode, the transmitter output is connected to the receiver input. In the
scanning mode, the antenna is connected to the receiver through the transmit bandpass
filter. The same set of interconnects provides for loopback and normal operation as
well as the new scanning operation. The use of switches rather than couplers or
couplers for the loopback function reduces noise and crosstalk between transmit and
receive signal lines and lower losses in these lines.

Abstract: Proposed is an improvement in a multi-stage solvent extraction
process of a metal value such as rare earth elements from an acidic
feed solution containing the metal value in the form of a water-soluble
salt by bringing the aqueous solution into contact with a water-immiscible
organic extractant solution containing an extractant compound
which releases an acid when combined with the metal ions.
While the concentration of the acid in the aqueous feed solution is increased
when contacted with the organic extractant solution containing
an extractant agent of the above mentioned type so as to cause a
shift of the extraction equilibrium unfavorably against further extraction
of the metal ions, the acid in the aqueous feed solution prior
to contacting with the organic extractant solution in a succeeding
stage of extraction is at least partly decreased, instead of the conventional
expensive way of neutralization by the addition of an alkaline
neutralizing agent to the aqueous solution, by ion exchange dialysis
with dialyzing water through an anion exchange membrane.
