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.

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.

An information-storage media is provided that includes: (a) a substrate disk 312 having first and second opposing surfaces; (b) a first selected layer 304 on the first surface, the first selected layer having a first thickness; (c) a second selected layer 308 on the second surface, the second selected layer having a second thickness, wherein the first and second selected layers have a different chemical composition than the substrate disk; and (d) an information-storage layer 412 adjacent to one or both of the selected layers. The first and second thicknesses are different to provide an unequal stress distribution across the cross-section of the media.

A power-down biasing circuit includes a current source connected to a drain of a first NMOS transistor through a first switch. A gate of the first NMOS transistor is connected to the current source, and a source of the first NMOS transistor is connected to ground. A first pre-chargeable capacitor is connected between the gate of the first NMOS transistor and ground.

摘要:
A phase change memory comprises a first electrode formed over a substrate, a patterned phase change material layer formed over the first electrode to contact the first electrode and including a conductive material, and a second electrode formed over the patterned phase change material layer to contact the patterned phase change material layer. Instead of heat generation, the conductive channel is used to adjust resistance while maintaining characteristics of non-volatile memories. Hence, the power consumption can be reduced. Due to no use of the phase change, the shortened lifetime of equipment for fabricating semiconductor memories, usually caused by a volume change during the phase change, can be reduced.
