Title: Communication using spread spectrum methods over optical fibers
Inventor: WEBER JEAN-PIERRE
IPC: H04J13/00
Filed: 1998-07-27
Granted: 2000-06-11
Abstract: In a fiberoptical network, for example in a LAN, spread spectrum modulation is used, for example CDMA, by providing an electrical digital data signal to spreading means comprising a multiplier (41) also receiving the spreading code.  Then a modulation is made of the spread signal at radio frequencies, the signal being multiplied (49) by a subcarrier wave generated in an oscillator (47), whereby the data signal is carried on an RF subcarrier.  A control channel signal from a control unit (53) is added (51) to the modulated signal, so that the control signal will be located in the baseband.  The added signal is converted (55) to an optical signal transmitted on an output fiber.  The control channel signal can be TDMA-modulated using collision detection.  Making spectrum spreading in the electrical domain allows the use of standard components developed for example for mobile telephone systems.  No wavelength control and no optical filters are necessary, what allows a low cost system to be constructed.  Alternatively the spread-spectrum data signal can be located in the baseband and the control channel on a subcarrier or both the data and the control channel can be put on subcarriers.

Title: Method for producing embedded DRAM with the use of salicide manufacturing process
Inventor: LIN YUNG-CHANG
IPC: H01L27/108
Filed: 1998-08-15
Granted: 2000-06-01
Abstract: The present invention discloses a method for applying salicide manufacturing process to the process for producing embedded DRAM. With the method, an isolation layer is formed to only cover the source/drain region in the memory area of the DRAM after performing a rapid thermal process on the source/drain region. Next, a silicide layer is formed on the polysilicon gate, and silicide is simultaneously formed on the surface of the source/drain region in the logic area for decreasing the resistance. Because the formation of poly silicide layer before the rapid thermal process is not required, the manufacturing process can be simplified and there are no thermal stability and inner diffusion problems encountered.

Title: Loop control method for network switching
Inventor: HUANG YING-HUEI
IPC: H04L12/00
Filed: 1999-04-27
Granted: 2000-09-21
Abstract: The invention provides a loop control method for network switching, which is mainly used under the condition that the network switch operates normally. When multiple switches connect Ethernet networks located in different segments to form loops, any port is judged whether it is switched from the non-connection state to the connection state, and whether the present IEEE 802.1d is followed to execute the defined STA (Spanning Tree Algorithm). If it is positive, the state the port is set to be the listening state immediately to ensure the BPDUs (Bridge Protocol Data Units) transmitted according to STA having higher priority than any packet to be received, so that the bandwidth of Ethernet network occupied by the loop packets can be prevented effectively and the logic loop in network without having to concern the chance for BPDUs sent out according to STA network rule.

Title: Process for selectively producing C3 olefins in a fluid catalytic cracking process
Inventor: LADWIG PAUL KEVIN
IPC: C10G11/02
Filed: 1999-08-07
Granted: 2002-11-21
Abstract: A process for selectively producing C3 olefins from a catalytically cracked or thermally cracked naphtha stream. The naphtha stream is introduced into a process unit comprised of a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures ranging from about 500 DEG C to 650 DEG C and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone. Overhead products from the reaction zone are passed to a fractionation zone where a stream of C3's is recovered and a stream rich in C4 and/or C5 olefins is recycled to the stripping zone.

Title: Semiconductor laser device
Inventor: TANABE TESTSUHIRO
IPC: H01S5/00
Filed: 1999-05-19
Granted: 2000-10-21
Abstract: The semiconductor laser apparatus composite of this invention is: since the insulating film 34 formed between the upper electrode 28 and the second upper clad layer 30 will stop the current flowing from the upper electrode 28 toward the terminal portion of the optical waveguide 18a, it will not supply the current toward the terminal portion of the optical waveguide 18a. Therefore the temperature of the terminal portion (i.e., the current non-injection region 18b) will not increase due to joule heat, thus the contraction of a band gap due to the increase of temperature will be suppressed. Therefore it can prevent the contraction of a band gap in the terminal portion of the optical waveguide 18a, and can prevent instantaneous light damage caused by heating absorbed from the laser light. Besides, it could also prevent reduction of the light emitting efficiency or the complexity of process.
