In the data input apparatus, a data delay unit outputs data input from outside the data input apparatice. The data delay unit varies the degree of delay in response to a test mode signal. A data alignment signal generating unit receives a first signal synchronized with an external clock signal and a second signal synchronized with a data strobe signal, and the data alignment signal generating unit outputs one of the first signal and the second signal as a data alignment signal in response to the test mode signal. A data alignment unit is synchronized with the data alignment signal to align the data delayed in the data delay unit. The data input apparatus improves the setup / hold window when a semiconductor memory device is in the test mode.

A yarn winding apparatus for continuously winding yarns to packages. The winding apparatus has a plurality of winding spindles, which are mounted in cantilever fashion for rotation on a movable turret, and which are alternately guided between a winding position for winding the yarns and a doffing position for removing the packages and assembling fresh tubes. To put on the tubes on the winding spindle, a tube slip-on device is provided, which comprises a movable means for guiding the tubes. To make it possible to put on tubes on the winding spindles held in the doffing position even during the progressive movement of the turret, the guide means for slipping on the tubes is movable for a short time or distance synchronously with the winding spindle that is moved by rotation of the turret.

A packet data transmitting method for packet service domain is disclosed. After receiving a Service Data Unit (SDU), a Packet Data Convergence Protocol (PDCP) entity determines how to handle the SDU in a cache queue and process a Protocol Data Unit (PDU) record in a Serial Number (SN) window based on whether or not the cache queue includes any SDU and the SN window is full, respectively. When both the cache queue and the SN window are full, the PDCP entity processes PDU records in the SN window according to their respective weight values and processes an SDU in the cache queue into a new PDU accordingly. A packet data transmitting system for packet service domain is also disclosed, which can prolong the time window for confirming a PDU record in the SN window.

An optical switching apparatus comprises an optically resonant system (3, 12) and a pulse source configuration (1, 2) to direct first and second pulses (P1, P2) of optical radiation into the resonant system, the first pulse (P1) being configured to produce a coherent excitation of the resonant optical system so as to change its optical characteristics and the second pulse (P2) being of a phase to thereafter de-excite the coherent excitation produced by the first pulse. According to the invention, a device (13, 34) driveable externally of the resonant system such as an optical amplifier or a laser, maintains the coherence of the excitation produced by the first pulse until de-excited by the second pulse. The optically resonant system may comprise an optically responsive medium (3) which is capable of being switched into a state of coherent resonance or a resonant cavity.
