摘要:
An electrode assembly and a lithium ion secondary battery using the same capable of preventing a short circuit from being created in an outer peripheral portion of the electrode assembly. Uncoated areas of positive and negative electrode plates and an active material layer in the inner and outer peripheral portions of the electrode assembly are optimally aligned such that the thickness of the electrode assembly is uniformly formed widthwise along the electrode assembly.

A method and apparatus for implementing wireless internet connections for a plurality of portable computing devices located within a given area or hotspot. The invention employs a combination of wired and wireless links to manage propagation effects of the transmitted signal and to reduce interference with signals transmitted in adjacent spaces. In accordance with one aspect of the invention, the existing wiring infrastructure at the hotspot, which may be coaxial cable for CATV, is used as the wired segment. A broadband signal, containing internet data obtained from a central computer, is transmitted from a plurality of access points. The signals transmitted from the access points are injected onto the existing wiring, with the broadband signal isolated from the data or power signals carried by the wiring infrastructure. At the outlet ends of the coaxial cable, the broadband signals are separated from the existing data or power signals and coupled to high efficiency antennas which radiate a signal throughout the corresponding living or activity space. In the case of a hotel room, for example, the signal is broadcast for reception anywhere within the hotel room. In accordance with one aspect of the method of the invention, the broadband signals are broadcast from the various access points using several carrier frequencies or channels, and distribution of the channels is arranged to avoid adjacent room same channel interference.

Disclosed is a washing machine, including a lifter for protecting weight imbalance of a drum. The washing machine includes a housing, a tub provided in the housing for preliminarily storing wash water, a drum rotatably provided in the tub for washing laundry, at least one lifter provided on an inner circumferential surface of the drum for lifting the laundry to drop the laundry from a predetermined height during rotation of the drum so as to prevent the laundry from gathering to an inlet of the drum.
摘要:
A method and circuit are presented for the all optical recovery of the clock signal from an arbitrary optical data signal. The method involves two stages. A first stage preprocesses the optical signal by converting a NRZ signal to a PRZ signal, or if the input optical signal is RZ, by merely amplifying it. In a preferred embodiment this stage is implemented via an integrated SOA in each arm of an asymmetric interferometric device. The output of the preprocessing stage is fed to a clock recovery stage, which consists of a symmetric interferometer that locks on to the inherent clock signal by using the second stage input signal to trigger two optical sources to self oscillate at the clock rate. In a preferred embodiment the second stage is implemented via SOAs integrated in the arms of an interferometer, with two DFB lasers as terminuses. The output of the interferometer is an optical clock signal at the clock rate of the original input.

The present invention provides a method of purifying an aqueous dye solution having an aldehyde and/or ketone impurity including a step of reacting the impurity with a hydrazine derivative, forming a water-insoluble hydrazone compound. The hydrazone compound is then removed from the solution to form a dye having an increased purity.
摘要:
A magneto-optical recording apparatus including a carriage provided with a magnetic field generator and an optical pickup for recording a magneto-optical disc, a drive mechanism connected to the carriage for driving the carriage, and a guide for guiding the carriage radially of and parallel to the magneto-optical disc. The carriage is divided into an upper carriage and a lower carriage which are pivoted relative to each other. A guide bar having an upward bent portion is disposed at a side of the upper carriage. A side wing is formed at a side of the upper carriage and placed on the guide bar. The upper carriage is pivotally raised by the upward bent portion when unloading a magneto-optical disc. The optical pickup is aligned with the magnetic field generator to coincide a beam generating area with a magnetic field generating area.
