Title: Gas-fired hot water supplying device
Inventor: KIMURA YOUICHI
IPC: F24H1/10
Filed: 1984-04-24
Abstract: PURPOSE:To automatically shut-off the flow of gas to a main burner when the water pressure in a heat exchanger rises abnormally due to the occurrence of no water burning and, in addition, open the water passage in the connecting pipe of a feed water pipe when said water pressure rises further even after the stoppage of combustion so as to release the pressure outsise and consequently to prevent the heat exchanger and the water passage from being damaged by a structure wherein a piston with a spring is assembled in the mouth of connecting pipe of the feed water pipe. CONSTITUTION:When no water burning occurs, the water pressure in a heat exchanger rises. As a result, the water pressure applied on a piston 16 also rises, resulting in moving the piston 16 downwards against the force of a spring 18. Consequently, a rod 17 also moves downwards, resulting in turning ON a shut-off valve actuating switch 15 so as to close a shut-off valve 11 through an electronic control device 12 in order to stop the flow of gas and accordingly stop the combustion. When said pressure is applied further more, the piston 16 moves further downwards, resulting in clearing a pressure release port 23 and escaping the pressure outside. Thus, when no water burning occurs, the combustion can be stopped without employing any temperature sensing device, resulting in preventing the heat exchanger and the water passage from being damaged. In addition, high pressure boiling water is prevented from jetting through the pressure release port.

This upper clamping member is so constituted as to move together with the clamping means 14, 16 for the covered parts at the time of the fusion connection of the optical fibers. The clamping force of the bare parts is, therefore, strongly stabilized and in addition, even if the outside diameter of the bare parts of the optical fibers fluctuates, such fluctuation is absorbed by the elastic body. The upper clamping member moves together with the clamping means for the covered part, thereby moving the bare parts together with the upper clamping member at the time of the fusion connection of the optical fibers. The optical fibers are thus connected with good accuracy without generating deflection between both the clamping means.

Title: Echo canceller
Inventor: TANAKA YOSHIAKI
IPC: H04B3/23
Filed: 1985-04-19
Abstract: PURPOSE:To increase a focusing speed by connecting a fixed filter having the known near-end echo pass characteristics in parallel to an adaptive filter. CONSTITUTION:The coefficient of a coefficient register 122 is controlled by a coefficient/gain control part 123 so that an error signal E is minimized. A transmission code S supplied previously is calculated and applied to an adder 15 via a multiplier 124. Then the code S undergoes an operation by the known near-end echo pass characteristic coefficient of a fixed filter 11 and is supplied to the adder 15. The output of the filter 11 is added with the output of an adaptive filter and a gain adapting circuit 14 performs control so as to minimize the signal E. Therefore the impulse response to be estimated by an echo canceller 1 is equal to the difference between the actual impulse response and the impulse response delivered from the filter 11. Thus the dynamic range is reduced by an amount equal to said difference of impulse responses. This increases the focusing speed of the canceller 1.
