Title: Voice signal transmission system
Inventor: WATANABE KAORU
IPC: H03M7/30
Filed: 1989-01-20
Abstract: PURPOSE:To regenerate an original voice signal having frequency characteristic of wide band by transmitting the original voice signal having a high frequency signal component after applying band limitation via a main transmission path, and transmitting a remaining high frequency component via a subtransmission path. CONSTITUTION:An original voice input signal (a) is divided into a signal (b) applied with frequency band limitation to the transmission band of the main transmission path by an LPF 1 and a subtractor 4, and a signal (d) having the high frequency component exceeding that of the signal (b). First sampling frequency conversion is applied on the signal (b) at a first sampling frequency converter 2, and the output signal (c) of the converter 2 is sent to the main transmission path via a signal delay circuit 3. Also, the signal (d) is applied with second sampling frequency conversion at a second sampling frequency converter 5, and outputs a signal (e), and the signal (e) is applied with bit compression at a bit compression device 6 at need, and is sent to the subtransmission path. Since the signal component not being transmitted on the subtransmission path due to the band limitation is transmitted to and attached on the signal transmitted from the main transmission path at a reception side, a voice signal of wide band can be recovered. Also, sound quality and interchangeability with reception equipment for main transmission path can be secured when a fault occurs.

Title: Method for measuring temperature of molten iron
Inventor: NAKAMURA YUJI
IPC: C21B7/24
Filed: 1988-01-20
Abstract: PURPOSE:To accurately and inexpensively measure the temp. of molten iron by substantially removing the effect of slag, by processing the measuring error of temp. due to luminous slag as the disturbance of measured data. CONSTITUTION:As a means for automatically correcting a measuring error, the standard deviation and average value are put in order on the basis of a certain threshold value. For example, when the standard deviation becomes too large, the data of the previous time is used as it is and, when the average value exceeds the certain threshold value, the emissivity of slag 16 is altered to correct a measured value. As mentioned above, only by adding a relatively inexpensive apparatus to a radiation thermometer converter 20, the measured value is processed using only the recording of temp. due to a radiation thermometer detector 14. By this method, a temp. measuring error can be automatically corrected and temp. can be measured easily and accurately.
