Title: Single-mode vertical cavity surface emitting laser device
Inventor: CHIU SU-WEI
IPC: H01S5/183
Filed: 2002-06-07
Granted: 2003-05-21
Abstract: The present invention relates to a single-mode vertical cavity surface emitting laser (VCSEL) device, which is to plate a layer of anti-reflective film on a conventional multi-mode vertical cavity surface emitting laser device, and to form a light emitting window on the anti-reflective film. Because the anti-reflective film can reduce the overall reflectivity of the multi-mode vertical cavity surface emitting laser device and the Bragg reflector on the bottom of the anti-reflective film, so that the current is injected into the area in which the flow direction is not covered by the anti-reflective film, and it is easier to form the single-mode laser, and output the single-mode laser through the light emitting window. Furthermore, with the optical power-current characteristic curve and the spectrum characteristic, it can be used to find the better current value, so that the present invention can control the output of the single-mode laser.

Title: System and method for early write to memory by injecting small voltage signal
Inventor: PILO HAROLD
IPC: G11C11/409
Filed: 2002-06-28
Granted: 2005-08-11
Abstract: A system and method is disclosed for writing early within a memory cycle by injecting a small voltage difference signal prior to setting a sense amplifier, and thereafter setting the sense amplifier which amplifies the small voltage signal to predetermined high and low voltage logic levels for writing to the memory cell. In this way, writing can complete in about the same time as reading, without risking corruption of data on adjacent bitlines in the memory. Local bitswitches apply first and second write voltages having a small voltage difference to a true bitline and a reference bitline prior to setting the sense amplifier. Local bitswitches on such other memory cells not currently being written are adapted to isolate true and reference bitlines coupled to those memory cells prior to the setting of sense amplifiers coupled to those bitlines, such that the stored contents of such memory cells not being written are refreshed at the time that the selected memory cell is written.

Title: Fast roaming system
Inventor: TSUTSUMI TAKAYUKI
IPC: H04W84/12
Filed: 2003-08-27
Granted: 2005-11-11
Abstract: A fast roaming system for changing, in a short period of time, the connection to a roaming destination AP (access point) providing a better communication environment, and for improving a roaming completion rate. In response to a search process performed by a mobile terminal, individual APs transmits AP data required for roaming directly to the mobile terminal. The mobile terminal performs the passive scanning search or the active scanning search for the peripheral APs at short time intervals, and obtains and stores the latest AP data in an AP data table. As a result, only the latest data for the connectable peripheral AP can be stored as a roaming destination in the AP data table. Furthermore, since the order condition is set by the mobile terminal to select the roaming destination AP, there is a high probability that the roaming is completed when the peripheral AP is first selected. Therefore, only a short period of time is required until the roaming is completed.

Productivity is increased so that the gland-packing material can be supplied at low cost. Furthermore, the gland-packing material (1) can be reinforced by providing carbon fibers or brittle fibers on the outer side of the cord-like body (40).
