Title: Method for controlling temperature of cooling zone for baking furnace
Inventor: TAKAI TADASHI
IPC: F27B9/40
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce a temperature change width in a cooling zone by controlling a rotational speed of an air forcing fan for forcing the air front an end of a baking furnace so that sensed temperature becomes a preset suitable temperature. SOLUTION: A controller 20 has an air forcing fan 22 for forcing the cooling air from an end of a baking furnace 10, and a thermocouple 24 as a temperature sensor for sensing temperature in the furnace of a cooling zone 16. The sensed temperature of the thermocouple 24 is converted into an electric signal, which is sent to a temperature regulator 26. The regulator 26 compares the sensed temperature of the thermocouple 24 with a preset suitable temperature, outputs an electric signal responsive to the difference to an inverter 28, and controls a rotational speed of the fan 22 via the inverter 28. Thus, a temperature change width of the zone 16 can be remarkably reduced.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To quicken the operating speed of a change-over switch and realize high speed printing by a method wherein a voltage short of discharging of coloring material particles is applied to the discharging electrodes outside both the adjacent discharging electrodes and, in addition, a discharging voltage is applied for controlling to an arbitrary discharging electrode for discharging coloring material particles.

The resistance values of resistors R1 and R2 must be set to a value, which does not exceed the maximum application voltage value at the base part of a transistor TR2. Then, by turning the TR2 ON and a TR3 OFF, a predetermined vias voltage Vb is generated by means of resistors R3 and R4 . Further, since transistors TR4, TR6, TR7 and TR9 are under OFF state, an arrowed Vc part and an arrowed Vp part are turned into non-grounded floating states. Furthermore, the voltage Vb generated only at the arrowed Vb is supplied to the discharging electrode.

Abstract: PURPOSE:To distribute evenly a mixture gas in all operating conditions by controlling either or both of the suction load and the atmosphere depending upon the warmed-up condition or revolving speed of the engine, and varying the protrusion amount of a sleeve to the divergent point of a suction manifold. CONSTITUTION:When an engine 5 is in operation, and electronic control device 24 passes a drive signal to a control valve 25 in accordance with the warmed-up condition and revolving speed of the engine on the basis of a program stored in advance, and introduces or shuts off the suction neg. pressure and atmosphere appropriately. Thereby the pressure of a control pressure chamber 16 is adjusted, and the amount of sleeve 10 protrusion to the divergent point is varied, and the rate of flow and the air-fuel ratio of the mixture gas to the cylinders are equalized. A flow of the mixture gas in a specific direction is obstructed by setting the max. protrusion amount of the sleeve 10 properly to provide good response to a wide variation of the distributiveness in the warming-up process. Even for an engine having such a characteristic that a remarkably uneven distribution of the mixture gas occurs in the middle and high revolution ranges, an equalized distribution is secured over the whole revolution range.
