Isonicotinanilide derivatives of the formula ##STR1## (wherein R.sub.1 is a hydrogen atom or a lower alkyl group; X is a halogen atom or methyl; n is an integer of from 0 to 2; R.sub.2 is phenyl, halo-substituted phenyl or a lower alkyl group; and Q is ##STR2## provided that Q is ##STR3## or --CH.sub.2 --when R.sub.2 is phenyl or halo-substituted phenyl, and Q is ##STR4## when R.sub.2 is a lower alkyl group) a process for preparing the same and a plant growth regulator containing the same are disclosed. The derivatives of the formula above have good activity for regulating the growth of various plants, especially of grassy plants.
摘要:
A plant growth regulator containing as an active ingredient one or more compounds represented by the formula ##STR1## wherein R, X, Y and Z are defined in the specification is disclosed. The plant growth regulator is effective for a wide variety of plants, particularly for grassy plants. In addition to such activity, the regulator of this invention acts on plants to thicken the foliage and to aid health growth without causing substantial phytotoxicity.

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.
