Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To improve economy by using fuel such as gas, and to unnecessitate movement corresponding to the positional change of the internal surface of a coil by measuring the outside diameter of the coil, calculating the position of the internal surface of the coil and making burners corresponding to this position burn. SOLUTION: An uncoiled bar is held between measuring rolls 5, the length of the uncoiled bar is taken out as the number of revolution, this number of revolution is taken out with a pulse generator 6 as the number of pulse. In the position opposite to the end face of coil, five burners p1-p5 for heat-retaining and heating the internal surface of the coil are arranged along a route on which the position of the internal surface of the coil is lowered with the decrease of the outside diameter. By a burner control part 7, the present outside diameter of the coil is calculated from the number of pulse from the pulse generator 6 and the outside diameter D0 of the coil at the time of starting the measurement of the uncoiled length which is previously inputted.  The position of the internal surface of the coil is determined when this outside diameter is obtained, so the burners pn near that position are fired two by two and heat- retaining and heating are executed.

Title: Echo canceler
Inventor: FUJII KENSAKU
IPC: H04B3/23
Filed: 1991-05-02
Abstract: PURPOSE:To keep stability by stopping the correction of the coefficient of a filter when an echo canceling amount is lower than a threshold value by inputting the ratio of average power between residual echo and pseudo echo to a primary cyclic low-pass filter. CONSTITUTION:In the case of the echo canceling amount in a size guaranteeing the stability of a system, the input of a double talk detection circuit 3 becomes residual echo E1, which is not limited in the case of single talk, and pseudo echo G1. An echo canceling amount calculation circuit 10 calculates the average power by cumulatively adding the square values of signals at integration circuits 11 and 12. A multiplier 13 multiplies a gain control coefficient (2-K)/2, and a driver 14 calculates the echo canceling amount. The canceling amount is calculated by the primary cyclic LPF equipped with multiplies 15 and 17, adder 16 and one-sample delay register 18. A comparator circuit 20 compares the canceling amount with the threshold value. When it is lower than the threshold value, it is judged as double talk, it is applied through a gate circuit 22 to a coefficient correction circuit 2 and the correcting operation is stopped. Thus, the double talk can be detected within an echo canceling range guaranteeing the stability of the system.

Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a control processor for accurately measuring clock frequencies in a short time without interrupting miniaturization or low costs. SOLUTION: This processor is provided with a normal operation mode and a frequency measurement mode. In this frequency measuring mode, a dimmer control terminal IOT1 originally assigned to a dimmer control signal 54 for controlling the brightness of the back light of a liquid crystal display screen is temporarily used as the output of a 1/n frequency-division signal 53 outputted from a programmable frequency-divider 24. Thus, it is not necessary to especially provide any terminal pin for measuring clock frequencies, and a clock signal 52 can be directly recognized by measuring the 1/n frequency-divided signal 53.  Therefore, the clock frequencies can be measured in a sharply short time compared with a conventional manner for checking the clock frequencies for several days by using clock display, and the increase of the number of terminal pins can be escaped so that the miniaturization of a device size and low costs can be attained.
