摘要： PURPOSE:To provide a toner excellent in resistance against yellowing which can be erased with irradiation of near infrared rays by incorporating a specified dye which absorbs near infrared rays, decolorizing agent, and UV absorbent. CONSTITUTION:This toner contains a binder resin, dye which absorbs near infrared rays expressed by formula I or II, and decolorizing agent expressed by formula III. Further, an UV absorbent is incorporated by 0.2-30 pts.wt. to 100 pts.wt. of the binder resin. In formulae I-III, X is halogen ion, perchloric ion, etc., R -R are hydrogen atoms, hydrocarbon groups, etc., Y is cation having absorption characteristics in a near infrared region, R -R are alkyl groups, aryl groups, and at least one of them is an alkyl group of 1-12 carbon number, R -R are hydrogen atoms, alkyl groups, etc. When the process to form letters or pictures with this toner on a image supporting body such as copy paper and to erase the letters or pictures is repeated, the letters and images can be erased but give no decolorization to the supporting body so that the supporting body can be repeatedly used.

摘要： PURPOSE:To improve light resistance by containing binding resin, a specific near infrared absorbing dye, and a decolorant specifying the combination ratio of a heat-resistant antioxidant to the binding resin. CONSTITUTION:A toner contains binding resin, a near infrared absorbing dye expressed by the formula I or the formula II, and a decolorant expressed by the formula III, and 0.05-30 pts.wt. of a heat-resistant antioxidant is combined to 100 pts.wt. of the binding resin. In the formula I, X indicates halogen ion or perchloric acid ion. In the formula II, R -R independently indicate hydrogen atom, hydrocarbon group, or hydrocarbon group containing hetero atom respectively, and Y indicates cation having the absorption characteristic in the near infrared region. In the formula III, R -R independently indicate alkyl group respectively, at least one of which is the alkyl group having the carbon number of 1-12, and R -R independently indicate hydrogen atom or alkyl group respectively. A toner having excellent light resistance during production and storage and having excellent light resistance of a formed image is obtained.

摘要： PURPOSE:To obtain the titled machine having a short rise time to perform stable material-supply regardless of the change or degree of viscosity, by setting the drive rotation number of a feed pump, which determines a component-mixing ratio, on the basis of pulses generated from a quartz oscillator. CONSTITUTION:A digital servo 5, 5, which digitally controls the rotation of each DC motor 6, 6 with a rate corresponding to a component mixing ratio, is constructed by a quartz oscillator 51, a frequency-dividing circuit 52, a digital setter 53, a comparing circuit 54, a D/A converter 55, a DC motor-controller 56, a pulse oscillator 57 and a tachogenerator 58. A digital signal representing a difference, between the pulse signal of frequency corresponding to the preset rotation number from the frequency-dividing circuit 52 and that corresponding to an actual rotation number from the pulse generator 57, is converted into an analog signal by the converter 55. Each DC motor 6 to drive a pump 3, 3 is controlled by the controller 56 in a manner such that its rotation number corresponds to the preset rotation number.

摘要： PURPOSE:To obtain an electromagnetic wave shielding device which is elastic, flexible, excellent in usability, and able to block an electromagnetic wave wider in frequency band by a method wherein the electromagnetic shielding device is formed of a mixed material composed of ferrite powders specified in average grain diameter and frame-retardant rubber mixed at a specific ratio. CONSTITUTION:A mixed material composed of ferrite powder and flame- retardant rubber is formed into a right circular cylinder through an extrusion molding method, and the molded body is vulcanized into a shielding cylinder 21. Mn-Zn ferrite composed of 30-70% by weight of MnO, 10-40% by weight of ZnO, and 10-60% by weight of Fe2O3 is used. Ferrite is made to amount to 60-85% by weight in content. Ferrite powder is set to 3-15mum in average grain diameter. By this setup, an electromagnetic shielding device is excellent in shielding capacity, and able to block an electromagnetic wave wider in frequency band, especially an electromagnetic wave lower in frequency.
