Filed: 1989-09-05
Abstract: PURPOSE:To perform the addition of binary numbers at a high speed without increasing the scale of an addition circuit by providing plural adders, carry calculators, and carry correctors. CONSTITUTION:The binary numbers (a15 - a0) and (b15 - b0) are divided every prescribed bits (4) and given to adders 9A - 9D. The carry calculators 13B - 13D calculate the carry data e8, e12 and e16 on the bits higher than the pre scribed ones (4) based on the results of addition of the adders. The carry correctors 12B - 12D add the carry data e8 - e16 to the results of addition of the adders 9B - 9D within the prescribed bits. The carry data exceeding the prescribed bits are neglected. In such a constitution, the time required for addi tion of binary numbers is approximately equal to the sum of the computing time of a single adder and three carry calculators and can be shortened.

Title: Wick type liquid fuel burner
Inventor: KUMAZAWA KATSUYOSHI
IPC: F23D3/18
Filed: 1986-09-30
Abstract: PURPOSE:To keep balance between air and fuel to hold a low combustion by forming vent holes in an inside flame cylinder top plate provided at the upper end of an inside flame cylinder, and providing a control plate for controlling the opening and closing state of the vent holes. CONSTITUTION:The burner is fired with air from vent holes 8 and 12 through the ignition of a wick 5, and a steady combustion where the entrance and exist of heat of the wick 5 are balanced occurs. At the time of a high combustion, since the vent holes formed in an inside flame cylinder top plate 10 is closed by turning a control plate 22 by a control lever, air goes out of a vent hole 8 and burns. Therefore, the temperature at the upper part of a combustion chamber 4 is raised to increase the draft. In the vicinity of the wick 5 a steam pressure is produced to promote the fuel evaporation. At the time of a low combustion, the lever is lowered to fully open the vent hole 9 of an inside flame cylinder top plate 10, and combustion air is branched to vent holes 8 and 9 so that combustion air for the combustion chamber is reduced and the concentration of the fuel is increased. Flames of outside flame cylinders 1 and 2 rise up and the temperature at the lower part of the combustion chamber 4 is lowered and the combustion capacity is reduced. Waste gas is prevented from generating CO by the reduction of air in the inside flame cylinder 1.

A current copier 14 stores the residual current in the 1st operation cycle and generates an output current from the residual current stored at an output node 18 to output it in a 2nd operation cycle. Then the copier 10 reduces the output mutual conductance to reduce the deviation of the output current.
