Abstract: PROBLEM TO BE SOLVED: To provide an orthogonal complex spreading method and its system for a multiplex channel by which a problem of unbalanced power between in-phase channels and orthogonal phase channels is solved, and which has an advantage over complex spreading systems proposed by CDMA-ONE in the U.S. and by W-CDMA in Japan and Europe, from the standpoint of power efficiency. SOLUTION: 'Orthogonal complex spread miodulation' is called an OCQPSK (orthogonal complex QPSK). Data for a multiplex channel and subject to gain and orthogonal Hadamard sequence for each channel, two channel data multiplied with the gain and the orthogonal Hadamard sequence are summed in a complex form, a complex multiplier applies complex multiplication to the value summed in the complex form and the outer orthogonal Hadamard sequence in a complex form, and provides outputs of in-phase information and orthogonal phase information. The in- phase information outputted from lots of blocks is summed to the in-phase information and the orthogonal phase information is summed to the orthogonal phase information, and the result is spread by using a spread code in the orthogonal complex spread method for the multiplex channel.

Abstract: PROBLEM TO BE SOLVED: To improve productivity of a system and its efficiency by generating an optimum schedule for minimizing flow time as one of system performance. SOLUTION: An initial solution is generated, f(X) is calculated and BEST- ID =K and BEST- F=(X) are conditioned.

A schedule X-a is generated and on the condition of L=1, a parameter OFB is defined as a large value MAX. In the case of L>n, the condition of Y=Xa ,b is generated, f(Y) is calculated and on the condition of f(X)>f(Y) and BEST- F>f(Y), it is replaced with BEST- ID=Y and BEST- F=f(Y). A random number R belongs to (0, 1) is generated by the replacement with X=Y and f(X)=f(Y) and the condition of P(A)=exp(-(f(X)-(f(Y)/Ck ) is found.

Abstract: PROBLEM TO BE SOLVED: To facilitate the separation of a model and to enable the distributed simulation on complicated problems by simulating rolling process using a real time distributed model. SOLUTION: The simulation model of one rolling process is divided into real-time objects(RTO) of rolling and control. The former is divided into the RTO of a pay-off reel, tensin reel and each work roll and also the latter is divided into the RTO of a rolling speed controller and each automatic thickness controller. At the time of simulation, first, a communication channel is formed between the simulation RTO method and the RTO, the initial values of the simulation are allocated, parameters of the rolling process or the like is read in and the result value of simulation by the model is made to approach the target value. A means (object data store method) for recoding this parameter of rolling process when the parameter approaches the target value by a data space method of the RTO is repeated according to the period of simulation.

Abstract: PROBLEM TO BE SOLVED: To always keep a monitor to a fixed standard state by comparing/ analyzing the voltage data measured with a sensor with the standard data and adjusting voltages of voltage supply devices of red, green, blue supplying the voltages to the electron guns of the monitor. SOLUTION: The sensor 50 measures voltages for three beams by the command of a processor 20 to send the measured voltages to the processor 20 together with the data of the color temp. state of the present monitor. The processor 20 compares the beforehand inputted data for the voltages of three beams in a standard white luminance state for the color temp. of the relevant monitor with the collected data, and judges whether or not the collected data exist within the range of the error of the standard data, and when out or the range, judges whether or not the voltage of the sensor data is lower than the voltage of the standard data, and when lower, instructs a controller to increase the voltages of the electron guns, and when higher, instructs to lower the voltages.

Abstract: PROBLEM TO BE SOLVED: To improve the naturalness of a synthesized voice and to synchronize multimedia and a text/voice converter(TTS) with each other by defining information needed to interlock additional metrical information other than a text and multimedia information and an interface between those pieces of information and the TTS by the TTS, and using them for synthesized voice generation. SOLUTION: A multimedia information input part 10 consists of synchronized information of a text, metrical information, and a moving picture. A data-by- media distributor 11 separates multimedia information by media, converts it into usable data structures, and transmits them. A language processing part 12 converts them by phonemes and estimates and symbolizes the metrical information. A metrical processing part 13 calculates the values of metrical control parameters other than metrical control parameters of the multimedia information. A synchronism adjuster 14 adjusts times by duration by phonemes for synchronizing a synthesized voice to a video signal. A signal processing part 15 receives the metrical information, etc., and generates a synthesized voice by making use of a synthesis unit data base 16.

Abstract: PROBLEM TO BE SOLVED: To improve the service reception ability of a switching device by dynamically constituting the number of the group unit reception links of the links and receiving the links having different speeds through one switch network. SOLUTION: A route to an output port through an output link 9 and a route to a recirculation route line concentration network 3 through a bypass link 10 are allocated to a cell which is inputted from an input link 7 and a cell inputted from a recirculation input link 8 by the comparison process of a self- target destination address and an output port grouping address from an output grouping address generation part 6. The cell to which a route to the bypass link 10 has been allocated returns to the recirculation input link 8. Thus, the input/output links 7 and 9 having different speeds can be received simultaneously at one switching system.
