Inventor: HEMMI AKIKO
IPC: C08F20/04
Filed: 2001-07-04
Abstract: A low-molecular (meth)acrylic add (salt)-based polymer having a
good color tone is obtained by polymerizing an aqueous solution of at
least one monomer component of a high concentration in the presence of
an alkaline. substance, wherein: 100 to 95 mol % of the at least one.
monomer component is a monoethylenically unsaturated
monocarboxylic add (salt) monomer (a) having 3 to 6 carbon atoms; and 0
to 5 mol % of the at least one. monomer component is a
monoethylenically unsaturated monomer (b) copolymerizable with the
monomer (a) (wherein the total of (a) and (b) is 100 mol %); and wherein:
a persulfate salt and hydrogen peroxide are used together as
polymerization catalysts; and the entirety of the alkaline substance as used
is set not to be more than 99 mol % of the amount which is necessary for
neutralizing all add groups of the at least one monomer component; and
wherein: the dropwise addition of the hydrogen peroxide is completed at
the. latest 10 minutes earlier than the completion time of the. dropwise
addition of the at least one monomer component; and/or the amount of
the hydrogen peroxide as added till the initiation of the dropwise addition
of the at least one monomer component is kept from exceeding 10 % of
the entirety of the. hydrogen peroxide as added. The resultant polymer is

IPC: H01M4/36

Abstract: In accordance with the non-aqueous electrolyte
secondary battery of the invention and the process for the
preparation thereof, charging is carried out with a
combination of a positive electrode provided with excess
lithium and a negative electrode in order to cause lithium
to be deposited on the negative electrode. Accordingly, no
oxidized surface film is interposed between lithium and the
current collector of negative electrode or the negative
active material layer as in the case where a metallic
lithium foil is laminated on the negative electrode. In
this arrangement, a battery having a small internal
resistance can be provided. Since the deposition of
lithium is conducted in the assembled battery, lithium does
not come in contact with air, preventing the formation of a
thick ununiform oxidized film on the surface thereof. 
Thus, the deposition of dendrite can be inhibited, making
it possible to inhibit the drop of battery capacity and
hence provide a battery having an excellent cycle life
performance. Further, lithium can be retained on the
negative electrode in an amount excess to the capacity of
the positive electrode. Accordingly, even when lithium is
lost due to the deposition of dendrite or the reaction with
the electrolyte solution, the drop of battery capacity can
be inhibited because the negative electrode is provided
with excess lithium.

Title: Wavelength agile optical transponder for bi-directional, single fiber WDM system testing
Inventor: FOLTZER LAWRENCE E
IPC: H04J14/02
Filed: 2001-12-14
Abstract: A wavelength agile optical transponder system and method
for testing a fiber optic link formed of a single fiber. An
optical source coupled to the optic link provides a signal at
a first wavelength which is propagated towards a wavelength
division multiplex (WDM) coupler disposed on the optic link.
Upon receiving the optical signal by a receiver, an optical
cross-connect arrangement is utilized for transmitting the
optical signal after translating its wavelength into a second
wavelength. By evaluating the optical signal in the optical
loop-back thus effectuated, the path integrity of the optic
link is determined without having to know the wavelength of
the incident signal or direction of transmission.

Abstract: A system and method for writing to an optical media 112 are disclosed. In a preferred
embodiment, a write controller 102 monitors the amount of data in an optical writer's buffer
108. The write controller further monitors the rate at which data is being supplied to the
optical writer's buffer. The writer controller interacts with the laser optics 110 and servo 114
of the optical writer to dynamically adjust the speed at which data is written to the optical
media based upon the amount of data in the optical writer's buffer and the rate at which data
is being supplied to such buffer. In a preferred embodiment, the write controller decreases
the write speed if the amount of data in the optical writer's buffer drops below a threshold
amount. Moreover, in a preferred embodiment, the write controller decreases the write speed
if the rate at which data is being supplied to the optical writer's buffer decreases below a
threshold amount. Also, the write controller increases the write speed if the amount of data in
the optical writer's buffer is above a "safe" threshold. Thus, rather than the write speed being
locked into a set speed for the entire write to an optical media, the optical writer varies its
write speed to provide optimum performance while also avoiding buffer underrun errors.

Abstract: Two-dimensional barcodes surrounded by a quiet zone of white space which
may or may not include a border, each barcode having encoded digital information
in a bitmap representing preferably randomized encoded data bits, are printed onto
a printed medium. To extract the encoded digital information from the printed
medium, the printed medium is scanned, then the bitmap is located within the
printed medium by moving a window, in stepwise fashion in a predetermined pattern
across the printed medium. At each step the portion of the printed medium which
is encompassed by the window is tested to determine whether it conforms to one or
more characteristics of the bitmap. The skew of the bitmap, if any, is determined, by
using a finite-state recognizer in combination with a Hough Transform calculation.
In one embodiment, the candidate region is divided into a plurality of horizontal
regions, preliminary skew angles are calculated for each region, and the actual skew
angle is selected using a voting scheme. Once the skew angle is calculated, the
bitmap is deskewed if necessary, cropped, and the randomized digital information is
read from the bitmap. Finally, the digital information is derandomized and any error
correction codes are removed, in the process correcting and/or recording any errors
discovered, thereby reproducing the original encoded digital information.

Abstract: A temperature-responsively operated drive mechanism
29 is designed to provide a switching drive force to
switching-type indicating means 10 placed on a freeze-indicating
sign system. The temperature-responsively
operated drive mechanism 29 includes members 35 and 36 made

force to the switching-type indicating means 10 in
accordance with a temperature such as a predetermined
temperature, and a drive force assisting means 50 for
providing an assist force for assisting in the switching
drive force during switching operation of the members made
35 and 36 of the shape memory alloy. Therefore, the speed
of switching turning movement of the switching-type
indicating means 10 in the freeze-indicating sign system
can be increased, whereby the switching of the indications
on the switching-type indicating means 10 at the
predetermined temperature corresponding to a freezing
temperature can be conducted quickly and automatically,
thereby informing a driver or a road manager or the like of
the freezing of a road surface occurring in winter season.

Abstract: Dans un mode de réalisation de l'invention, un premier canal est affecté à la transmission de messages produits sporadiquement à partir de multiples unités de terrain vers une station de base. Le premier canal est de préférence divisé en créneaux temporels dans lesquels une unité de terrain transmet un message de demande d'accès à la station de base en vue d'établir une liaison de communication. En réponse à un message de demande d'accès, des informations de retour sont fournies de la station de base aux multiples unités de terrain ; ces informations indiquent si une collision a été détectée sur le premier canal pour un message transmis dans un créneau temporel précédent. Si une collision a été détectée, l'unité de terrain va retransmettre un message de demande d'accès à un réglage de niveau de puissance précédent, sur la base d'un temps de réduction de puissance aléatoire. Si aucune collision n'est détectée et que la station de base ne parvient pas à transmettre un message d'accusé de réception à l'unité de terrain demandant l'accès, le niveau de puissance de sortie de cette unité est augmenté pour les transmissions de message suivantes jusqu'à ce que le message soit reçu.
