Title: ATM time stamped queuing
Inventor: PETERSEN LARS-GORAN
IPC: H04L12/56
Filed: 1998-12-15
Granted: 2001-02-11
Abstract: A queuing system (230) stores a package (246) derived from an ATM cell, the package including an internal interface header (IIH) and either and ATM cell payload or an AAL2 packet. The queuing system comprises a queue (312, 320) for storing the package, as well as a processor which executes plural functions. A time stamping function applies a time stamp upon storage of the package in the queue. The time stamping function can apply the time stamp to a package as replacement of the internal interface header. A time stamp checking function uses the time stamp to make a determination whether the tenure of the package in the queue is longer than permissible. The time stamp checking function can make the tenure determination in conjunction with a potential readout of the package from the queue. Alternatively, time stamp checking function can make the tenure determination when invoked by a queue monitoring function which monitors a fill level of the queue (e.g., when a queue fill level exceeds a threshold). A discard function is provided for discarding the package if the tenure of the package in the queue is longer than permissible.

Title: A method for demodulating a carrier wave modulated by a digital symbol sequence
Inventor: CINKLER KALMAN
IPC: H04L27/233
Filed: 1999-04-07
Granted: 2000-11-21
Abstract: The invention relates to a method for demodulating a carrier wave modulated by a digital symbol sequence and transmitted via a noisy channel. According to the invention the ideal shapes of the edges of the possible transitions between two symbols are known and stored (reference edges), and a received edge is scanned and digitized at a scanning frequency which is equal to a multiple of the frequency of the symbol sequence. According to the invention, for the detection of a received and scanned edge the total scanning values are used to obtain the Euclidean distances to at least two reference edges and the reference edge with the shortest Euclidean distance is selected. In a preferred version, a Viterbi algorithm is not, as in the case of known CPM demodulation methods, applied to an estimated symbol sequence but to a sequence of estimated edges, whereby the corresponding Euclidean distances of the edge received during a symbol duration are treated by the reference edges as the cost of a Trellis branch of the Viterbi algorithm.

Title: Sealed battery suited to production in a slim rectangular form
Inventor: MIYAZAKI NORIYUKI
IPC: H01M50/169
Filed: 2000-03-15
Granted: 2001-11-11
Abstract: A sealed battery has an opening in an external casing sealed using a sealing plate that is laser welded to external casing. The sealing plate has a drop formed near a perimeter of the external surface of the sealing plate so that the surface of the sealing plate is higher at a perimeter of the sealing plate than at a more central position. When the sealing plate is laser welded to the rim of the external casing, the presence of the drop means that there is no direct thermal conduction path from the welded parts to the center of the sealing plate, which reduces the dissipation of heat away from the welded parts. As a result, there is a reduction in the thermal stresses that occur at the welded parts, which means that the formation of cracks in the welded joins can be suppressed, even when a low-power laser beam is used.

Title: Method of raising the anti-penetration effects of boron for dual gate complementary metal oxide semiconductor transistors
Inventor: CHEN CHI-CHIUN
IPC: H01L21/265
Filed: 2000-08-16
Granted: 2001-09-21
Abstract: The present invention relates to a kind of method for raising the anti-penetration effects of boron for dual gate complementary metal oxide semiconductor (CMOS) transistors. At first, boron ions (B+) are implanted into the polysilicon layer as the gate doping of p-type transistor in order to avoid the fluorine ion accelerated boron penetration effects. After completing the definition of gate electrode by etching the polysilicon layer, boron difluoride (BF2+) is implanted to form the extending region of source/drain (or source/drain doping) in order to complete a super shallow junction. The gate photoresist of previously defined gate pattern can exactly block the penetration of boron difluoride into the gate electrode such that the self-aligned effect is obtained and no extra mask or process is required. In this manner, not only the capability of resisting the effects of boron penetration for the p-type device of dual gate CMOS transistors is increased, but also the effect of super shallow junction can be completed through the use of boron difluoride, in which the effects will be even prominent if the nitrogen treatment of gate oxide layer is used together. This method is greatly helpful for the improvements of device reliability and yield control.

Title: Method and devices for servo-control
Inventor: TSUTSUI KAZUHIKO
IPC: H02P29/00
Filed: 2000-11-16
Granted: 2001-12-21
Abstract: A desired location is calculated based on an ideal servo system model. Within the predetermined period of time that the desired location rotates in a reverse direction, the predetermined gain is multiplied by the difference between the ideal location as calculated and the actual location to serve as a calibrated value, which is added to a speed command. As such, the errors of the calibrated effects due to the long-term changes in friction and various operation conditions can be controlled. Even in a mechanical system the experiences twisting of the screw nut of a screw rod or the increased deformation of a seal material, the unsteadiness of the servo system can be prevented while the bite-in caused by the calibrated reverse twisting is also reduced.
