Title: Two-wire type bidirectional amplifier system
Inventor: FURUYA SENJI
IPC: H04B3/23
Filed: 1980-08-27
Abstract: PURPOSE:To prevent the deterioration in quality of call due to level contrast, by reducing the amount of loss of one variable amplifying circuit by the amount corresponding to echo erasion, through the output of a detection circuit estimating the amount of erasion of echo. CONSTITUTION:When a signal comes from two-wire side at the E side, an echo erasing circuit 12 is operated to cancel the amount of echo produced at two/four- wire conversion point 4, the amount of echo erasion is estimated at an echo erasing amount detection circuit 20 and control is made so that the amount of loss of a variable gain amplifying circuit 6' at the W side can be reduced within the amount of erasion. When a call signal comes also to the W side from this state, the output of the circuit 20 is held. Next, when call is by the W side only, the circuit 6' at the W side becomes the gain and the circuit 5' becomes the loss and the loss of the circuit 5' can be reduced by the range of the amount of erasion. Thus, the loss inserted to the opposing side can be reduced to the same gain as that toward call with the amount of erasion.

Title: Combustion device
Inventor: KAWAMURA KIMINARI
IPC: F23N5/24
Filed: 1994-05-31
Abstract: PURPOSE:To prevent an abnormal operation such as incomplete combustion from being generated by a method wherein a difference between a concentration of O2 and its target value is calculated, and a combustion is stopped when a trend of variation in differences is coincided to each of a unit time having a specified period and a preceding unit time, respectively. CONSTITUTION:An air valve 4 and a combustion valve 3 are driven in reference to an amount of fuel and an amount of combustion air. The amount of combustion air is corrected as follows. A detected concentration value Ox of O2 detected by an o. sensor 11 is compared with a target value of concentration O2 of oxygen for keeping the most preferable predetermined combustion state. A feed-back control of correction of an amount of air is carried out in reference to a difference value ex obtained through the comparison above and then an opening degree of an air valve 4 is determined. It is judged whether or not trends of variations of differences ex at a unit time of a specified period and a preceding unit time may be coincided to each other. In the case that the two trends are coincided to each other through this judgement a fuel shielding valve 9 is shielded so as to stop combustion at the burner 1. In the case that the two trends are not coincided to each other, the operation is returned to a correction of air volume.

Title: Kerosene combustion device
Inventor: SAKAMOTO TADASHI
IPC: F23D3/28
Filed: 1984-06-08
Abstract: PURPOSE:To prevent the formation and accumulation of tar on a wick, inner and outer pans, by improving the shape of carburetion/mixing chamber. CONSTITUTION:A kerosene gas A volatilized from a wick 2 is burnt, while moving upwardly and mixing with a combustion air flowed under a combustion draft from small-diameter holes 7, 8 defined through the inclined wall surfaces of inner and outer pans 4, 6. The presence of small-diameter holes 7, 8 through the inclined wall surfaces provides only a reduced flow resistance of air flowing through these holes 7, 8, and thus an air may enter there into despite a small draft around the holes 7, 8. Because the flow of air passing through small- diameter holes 7, 8 imposes an affect upon the wick and its adjacent area, and therefore the volatilized gas of kerosene A may not remain inside a carburetor/ mixing chamber for longer period. Thus, the concentration of kerosene gas A is so lean as to prevent the accumulation of tar on the wick 2, inner and outer pans 4, 6, which is the processes the drawing-liqufying-oxidizing modification-tar forming of residual kerosene gas A. The device is thus usable comfortably for longer period, with no offensive smells or soots being accompanied.
