Title: Electric absorption type optical modulator drive circuit
Inventor: SUZUKI MASATOSHI
IPC: H04B10/80
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent damage in an electric absorption type optical modulator by controlling so as not to apply a forward voltage to the electric absorption type optical modulator even in an instance such as that an applied voltage to the electric absorption type optical modulator is kept to a prescribed value or above, etc., when a power source of a drive circuit is raised and lowered. SOLUTION: When the power source of the drive circuit 1 is raised, a charge circuit 7 is charged by a DC bias voltage source 2, and the charged voltage is applied from a bias tee 4 to the electric absorption type optical modulator 5. When the charged voltage becomes a threshold value or above, a switch 10a is closed after a prescribed delay by a voltage detector 9, and an AC modulation voltage source 3 is connected to the bias tee 4, and the DC bias voltage and the AC modulation voltage are applied to the optical modulator 5 together with each other. On the other hand, when the power source of the drive circuit 1 is lowered, though the switch 10a is turned off by a control circuit 8a, and the AC modulation voltage is interrupted, the DC bias voltage is lowered gradually while discharging the voltage charged in the charge circuit 7 to the optical modulator 5.

Title: Data transmission system in elevator controller
Inventor: YONEMOTO MASASHI
IPC: B66B3/00
Filed: 1987-04-30
Abstract: PURPOSE: To simplify operations for originating redundant bits and for detecting errors so as to simplify circuit constitution by adding redundant bits only to such specific signals as directly affecting passenger safety. CONSTITUTION: In data transmission by use of a cable 4 between a control board 1 and the controller 3 of a car 2, redundant codes R2 -R0 are not computed and added to all the bits D7 -D0 of transmitted signal data at the data transmission side, but only redundant codes are added to a limited number of specific bits among them, e.g. control data and detection data relating to passenger safety, and are transmitted. At the data reception side, errors are detected only for the specific bits. Thus, computations for originating the redundant bits and for detecting errors become so simple as to be achieved even by program computations without the need for complex special logic circuits, resulting in significant simplification of circuit constitution.

Title: Combustion in coke oven
Inventor: YAMAMURA HARUO
IPC: C10B21/10
Filed: 1982-06-23
Abstract: PURPOSE:To prevent air-cooled condition due to air infiltration during pause heating operation in a coke oven by controlling the fuel gas flow rate without changing in the pause period for the fuel gas to reduce the temperature difference between upper and lower part in the flue. CONSTITUTION:The fuel gas flow rate is controlled in a coke oven in such a manner that for the initial x-period of a period T (gas-heating switching cycle minus gas-flow switching cycle), an amount of the gas capable of adequate combustion by the air infiltrating through the gap of the completely closed air intake is fed, while for the remaining (T-x)-period, the optimum amount of the gas determined by the coke oven structure is fed. Thus, by controlling the average gas flow rate for the T with varying the x-value, the flue temperature differenc between upper and lower parts of the combustion chamber during a light-load operation of the oven is made as small as possible to prevent over-dry distillation in the lower part of the carbonizing chamber, thus trying to achieve energy saving.
