摘要： A laser diode control circuit comprises a load portion, a control portion, a bias current circuit portion, and a modulation current circuit portion. The load portion generates a signal V1 which corresponds to a photocurrent corresponding to an amount of light received in a monitoring photodetector for receiving light from a laser light generating portion. The control portion generates first and second control signals V2, V3 from a value Db, a value Dm, an amount of change &Dgr;Dm, and an amount of change &Dgr;Db. The amount of change &Dgr;Dm is generated using a function f(Db,&Dgr;Db)=&Dgr;Dm which is defined such that the light emission power and the extinction ratio become constant. The first control signal V2 is generated from &Dgr;Db and Db in order to modify a bias current Ib, whereas the second control signal V3 is generated from values corresponding to &Dgr;Dm and Dm in order to modify a modulation current Im.

摘要： A method for controlling an amount of electric charge on a finely divided powder. When the finely divided powder is supplied into a powder transportation pipe in a substantially discrete particle state and transported therethrough in a discrete particle state by a stream of a compressed gas having a very small water content whose dew-point is 0.degree. C. or less, electric charge is inevitably produced by friction on the powder by the collision thereof against the inner wall of the transportation pipe. By controlling the dew-point of the compressed gas, the amount of frictional electric charge produced on the powder can be controlled even if there is a change in the type of the finely divided powder, the piping system, the spray nozzle, the type and state of the gas serving as a carrier medium, and environmental conditions such as the atmosphere. Further, a finely divided powder spraying method and apparatus uniformly spray the powder, whose amount of frictional electric charge is controlled as described above, onto a grounded sheet surface in a discrete particle state by means of a two-dimensionally-swinging nozzle.
