    摘要： Semi-hard magnetic materials exhibiting an excellent square hysteresis loop are prepared by the following steps. An alloy material consisting essentially, by weight, of 73-93% Co, 1-5%Nb and the balance Fe is subjected to process annealing at not lower than 900.degree. C and cold working at a reduction of area of not less than 75% and then is subjected to any combination treatment involving one or more stress relief annealings at a temperature in the range 500.degree.-700.degree. C for a short period of time such that no intermetallic compound precipitates in said alloy followed by cooling to the ambient temperature, and one or more ageing treatments of said cooled material at a temperature in the range 600.degree.-900.degree. C for a considerably longer time such that an intermetallic compound does precipitate in said alloy.

    摘要： The emission intensity of a laser beam source, at a time when a laser beam emitted from the laser beam source and scanned by an optical scanning device becomes incident to a laser beam detector provided in a predetermined position on the scanning path of the laser beam in order to hold a position of an electrostatic latent image formed on a photoreceptor constant in the main scanning direction, while at the same time, changing the emission intensity of the laser beam, is set so as to become the consistently same emission intensity regardless of a change in emission intensity at the time of electrostatic latent image formation onto a photoreceptor. This allows the detection timing of a laser beam by a laser beam detector to be kept constant.

    摘要： A differential sensitivity calculation portion calculates the differential sensitivity D of a toner concentration sensor, using an output voltage V1 and V2 of the toner concentration sensor when a toner chamber is in a state of toner concentration T1 and T2 at the time of initial operation of a printer, or at some other time. A toner replenishment control portion takes as input a current output voltage Vs output from the toner concentration sensor, calculates the toner concentration in the toner chamber using the output voltage Vs and the differential sensitivity D calculated by the differential sensitivity calculation portion, and outputs a control signal to a toner replenishment motor so as to maintain the toner concentration in the toner chamber at an appropriate concentration.
