Title: Burning equipment
Inventor: KONAKAWA KATSUZO
IPC: F23D11/40
Filed: 1987-05-06
Abstract: PURPOSE:To maintain a stable combustion state by means of a combustion part, by a method wherein the combustion part is formed of a cylindrical porous material, a flow uniformizing cylinder having a flow uniforming space and a multihole is situated inside the combustion part, a close plate is located in a manner to cover a part in a radial direction of the combustion part, and at least a part of the porous material covered with the closing plate is brought into film contact with the flow uniformizing cylinder. CONSTITUTION:A combustion part 1 is a total primary combustion burner where a wire net 3 is slidably mounted to the outside of a flow uniformizing cylinder 2 of a punching plate having a number of pores to form a burner port. A closing plate 11 is situated in a manner to cover a part in a radial direction of the wire net 3, end parts 12 and 13 of the closing plate 11 are brought into firm contact with the wire net 3 of a porous material, and the flow uniformizing cylinder 2 makes contact with the wire net 3 which is protruded at partial parts 14 and 15 being a firm contact part. Since flame is not formed to the combustion part 1 covered with the closing plate 11, the combustion part is kept at a low temperature. Since the flow uniformizing cylinder 2 is brought into firm contact with the combustion part 1, the heat of the combustion part 1 is transferred to the flow uniforming cylinder 2. Since a stress produced due to temperature expansion is absorbed by a low temperature part and the flow uniformizing cylinder 2, a stress does not remain in the radial direction of the combustion part of a porous material formed by a wire net and the like, combustion part is prevented from worsening combustion characteristics due to deformation and crack, and a stable combustion state is maintained by the combustion part 1.

Title: Echo canceller
Inventor: NAKAJO KAORU
IPC: H04B3/23
Filed: 1988-05-06
Abstract: PURPOSE:To allow the canceller trace the characteristic quickly even if the characteristic of the echo path changes suddenly by deciding an echo suppression quantity from a received power and a residual echo signal power so as to change over the switch and inputting a training signal. CONSTITUTION:A received power is calculated from a reception power calculation section 4 and a residual echo power is calculated from a residual echo signal power calculation section 5. Then the power is fed to an echo suppression quantity decision section 6 and since the echo canceller cannot trace a sudden change in the echo path even if the sudden change takes place from the relation between the reception power and the residual echo power, it is decided that the echo suppression is reduced considerably. Then the echo suppression decision section 6 switches the switch 3 to the position of a training signal generating section 2. Then a training signal such as white noise used at the start of operation is given again to the simulated echo signal generating section 1 to update the tap coefficient of the adaptive filter, thus, the actual reception signal is used by the re-training to update the tap coefficient more quickly than the tracing to the change in the echo path.

Abstract: PURPOSE:To make a less-expensive device and improve a heat processing performance by a method wherein a heat treating furnace is provided with a nozzle for injecting cooling gas toward a treated item and a nozzle position varying mechanism for use in moving the nozzle between an inner position of a heat insulating wall and an outer position. CONSTITUTION:After a processed item 70 is inserted into a heat insulating wall 20, when a heating heater 30 is energized while being placed at a place where nozzles 60a and 60b are placed at an outer position of a heat insulating wall 20, the heated item 70 is heated. After the nozzle is moved from the outer position of the heat insulating wall to the inner position by the nozzle position varying mechanism 50a and 50b, a driving of the cooling gas circulation mechanism 40 causes the processed item 70 kept at its heated condition to be cooled with cooling gas injected from an extremity end of the nozzle. With this arrangement, it is not necessary to use the nozzle of heat insulating material and an inner structure can be made simple. Since an effective opening area of the heat insulating wall 20 can be reduced, it is possible to improve a heat loss.
