Abstract: A molten glass supply device is provided, which can solve unavoidable problems for high viscosity characteristics in connection with the conventional molten glass supply device for high viscosity glass. Such problems include improperly high heating cost caused by excessive heat radiation in a melting furnace, reduction in the grade of products deriving from an excess amount of an erosion foreign material and reduction in the product yield. High viscosity molten glass having a property in which a temperature at which the molten glass exhibits a viscosity of 1000 poise is 1350° C. or higher is supplied to a forming device through a melting furnace, a distribution portion in communication with the outlet of the melting furnace, and a plurality of branch paths branching from the distribution portion. In the branch paths, distribution resistance providing portions that provide distribution resistance to molten glass passed through the branch paths are provided.

Abstract: A time difference .DELTA..tau. between the arrival of acoustic signals from sound sources to microphones 1, 2 is detected from output channel signals L, R from microphones 1, 2. By Fourier transform, the signals L, R are divided into respective frequency bands L(f1)-L(fn), R(f1)-R(fn). Differences .DELTA..tau.i (i=1, 2, . . . n) in the time-of-arrival of L(f1)-L(fn) and R(f1)-R(fn) to the microphones 1, 2 as well as a signal level difference .DELTA.Li are detected. L(f1)-L(fn), R(f1)-R(fn) are divided into a low range of fi<1/(2 .DELTA..tau.), a middle range of 1/(2 .DELTA..tau.) <fi<1/.DELTA..tau., and a high range of fi>1/.DELTA..tau.. Utilizing .DELTA..tau.i for the low range, .DELTA.Li and .DELTA..tau.i for the middle range and .DELTA.Li for the high range, a determination is made from which sound source L(fi), R(fi) are oncoming to deliver outputs separately for each sound source. The outputs are subject to an inverse Fourier transform for synthesis separately for each sound source.

Abstract: A polarization-independent optical isolator having a structure in which polarization dispersion is virtually eliminated by selecting the thickness and optical axis orientations of birefringent crystalline plates used in the isolator. The optical isolator of the present invention employs a combination of birefringent crystalline plates wherein the optical axis orientation of at least one birefringent crystalline plate in the optical isolator is different from the optical axis orientation of the remaining birefringent crystalline plates, and the polarization mode dispersion, which is induced when the beam propagates through the birefringent crystalline plate having a different optical axis orientation, is equal to the dispersion rate of the polarization mode dispersion attributable to the remaining birefringent crystalline plates and in a mutually inverse direction.

Abstract: In an audio communication control unit, audio signals from at least three terminals connected to a switching part are branched to left- and right-channels audio signals, then the left- and right-channel audio signals are processed using sound image control parameters in such a manner as to impart them with target positions different for each terminal, then all left-channel audio signals corresponding to the respective terminals are mixed together into a left-channel mixed audio signal and all the right-channel audio signals are mixed together into a right-channel mixed audio signal, and these left- and right-channel mixed audio signals are distributed and sent to all the connected terminals.

Abstract: A method of controlling a process having dead time is disclosed. This method obtains input evaluating criteria for setting values of process response outputs in relation to known input information, the input evaluating criteria being represented in one or more of the integral, proportional and differential type process responses. Fuzzy inference is used to estimate a variation in the process response output occurring upon lapse of a dead time or a control amount relating thereto on the basis of the value of an input evaluating criterion. The process is subjected to fuzzy PI (proportional and integral) control based on the estimated value.
