Abstract: A mono-component toner powder composition which exhibits reduced sensitivity to machine conditions and provides copies whose images are sharply defined having substantially reduced backgrounding and good image density. The composition comprises a plurality of discrete particles each comprising a thermoplastic binder, a magnetically responsive material and carbon black, in which:
 (a) the binder comprises from 40 to 70 weight percent of the composition and is selected from the group consisting of (i) polyester resins, (ii) copolymers of styrene monomers and at least one monomer selected from acrylate and methacrylate monomers, (iii) a wax component having a melting point in the range of from 45 to 150 DEG C, and (iv) a blend of the wax component and a thermoplastic organic resin, in which the weight ratio of the wax component to the thermoplastic organic resin is in the range of from 1:0.1 to 1:1;
 (b) the magnetically responsive material comprises from 30 to 60 weight percent of the composition, the magnetically responsive material being dispersed in the binder;
 (c) from 0.05 to 2 weight percent of the composition of a fluorine-modified alkyl siloxane dispersed in the binder, and
 (d) the carbon black comprises from 0.005 to 0.3 weight percent of the composition and is attached to the exterior surface of the particles thereof.

Abstract: A droplet 23 of ink 11 is expelled from a nozzle 13 in a wall 12, so as to strike a printing medium 24, by suddenly moving the wall 12 towards the ink 11 with which it is in contact. This movement is effected by energising a piezoelectric sleeve 18. The ink droplet 23 is expelled by virtue of the inertia of the ink resisting the movement of the wall and creating pressure. Practical embodiments are described in which the wall containing the nozzle is formed by the tapered end end of a capillary tube.

Abstract: An apparatus and a process for detecting an absolute value relating to mechanical movement of a member to be measured from a reference point (O<sub>ABS</sub>). The apparatus includes a detecting means (24) with a plurality of detectors (25, 26, 27) of which periods (P1, P2, P3) are different from each other. Each detector generates electric signal with its each period corresponding to movement of the member. The signals are stored in a memory. Then, absolute value of mechanical movement between one of the detectors and the member is specified by using of two values. The one is equal to values of multiplication between the period of the signal corresponding to the detector and an integer. The other is the stored value in the memory corresponding to the detector. The value of the integer is decided by using periods and stored values corresponding to other detectors.

Abstract: @ Memory access time, noise and costs are substantially reduced while reliability is increased by replacing fixed delay lines with a dynamic delay (41). This dynamic delay is placed on the same integrated circuit as the remainder of the memory access circuitry to eliminate tracking problems associated with off-chip delay lines. The dynamic delay element is activated after all of the row address strobe (RAS) bits have been generated. These RAS bits serve to strobe the row column address bits initially present on the address bus into the memory. After the delay time has elapsed an address multiplexor (43) switches column address bits onto the address bus to replace the prior row address bits. As soon as this switch is completed, column address strobe (CAS) bits are generated to strobe the column address bits into the memory.

Abstract: An FET linear power amplifying apparatus has an FET power amplifier and a distortion generator which produces a distortion signal indicative of a distortion component having the same amplitude and inverted phase as those of a distortion component produced by the FET power amplifier. The amplitude and the phase of the distortion signal are controlled in accordance with a control signal which depends upon the magnitude ratio of the input and output signals of the apparatus. The distortion component which will be produced by the FET power amplifier is compensated by the controlled distortion signal.

Abstract: The liquid medium of an exothermic process is cooled by including in the medium a particulate heat sink material, such as sodium sulphate decahydrate, that is substantially insoluble in the medium and which undergoes an endothermic phase change. Either as a result of this endothermic change, or as a result of a subsequent exothermic change, the heat sink material is again solid particulate material substantially insoluble in the medium. It may remain in the medium, forthe instance as a dispersion through a polymer gel, or it may be separated from the medium.

Abstract: A colored image-forming method is initiated by forming a latent image on an image retainer (1) in the form of a rotatable drum. Then, a powdered toner is caused to fly from a developer-feeding carrier (41) and adhere to the retainer (1) in the presence of an oscillating electric field. Similar steps are carried out using different powdered toners to superimpose toner images of different colors on the retainer (1). Each developer-feeding carrier (41) has a magnet member (42) to exert a magnetic force to the corresponding toner. A magnetic attracting force acting between the toner particles and the magnet member (42) becomes smaller according to the increase of the number of the repetition of the above steps.
