Title: Production of spherical toner for electrostatic copying
Inventor: ITOU MASAAKI
IPC: G03G9/087
Filed: 1978-11-20
Abstract: PURPOSE: To produce the spherical toner of good fluidity with a compact device at low temperature without danger for fire, etc. by adding a small amount of organic solvent to toner powder under mixing and stirring while cooling the stirring vessel having a built-in vane from the outside.  
     CONSTITUTION: Powder of mean grain sizes 0.5W20μ composed of, e.g., ferromagnetic material 30W80wt% in wax 20W70wt% as toner powder is mixed and stirred by being added with organic solvent 5W20pts.wt. based on toner 100pts.wt. by a revolving shaft 3 having a rotary vane 1, pulleys 4 and motor 5 while being cooled with a water jacket 2. The stirring speed is, e.g., peripheral speeds 600W 3200m/sec. and the toner temperature is so controlled as not to become its softening point or more. Next, the mixture is taken out, dried and classified to obtain the toner powder. In this way, the spherical toner of good evenness which requires considerably less amount of using solvent as compared to conventinoal methods may be obtained.

Title: Method and apparatus for measuring shape of roll
Inventor: OONO YUKIO
IPC: B21B27/02
Filed: 1982-08-17
Abstract: PURPOSE:To make it possible to obtain a raw material of a secondary product having an excellent shape as an intact rolled state, by accurately measuring the change in a roll shape due to abrasion and thermal expansion of a vertical roll, obtaining a reference for shifting the vertical roll, and directly measuring the amount of elastic deformation of a rolling mill. CONSTITUTION:The abrasion and thermal expansion of a vertical roll 1 becomes the change in a distance (b). The change in the distance (b) is measured by scanning a distance meter 28. The distance signal from the distance meter 28 and the position signal from a stepping cylinder 25 are displayed, e.g., on an oscilloscope. Then the shape of the vertical roll can be measured. In this case, the following phenomena should be prevented: the distance meters 28 and 28' do not perform perfectly parallel movement with respect to the center of the rolling axis due to the machining errors of parts and the like; therefore the distance signals do not represent the abrasion of the roll correctly; and the correct shape of the roll is not displayed. For this purpose, the signals, which are measured by the distance meter 28 and 28' when the roll is not used, are stored in a memory device. The stored measured signals are subtracted from the signal measured after the start of the rolling work by a comparing operator. The shape of the roll is displayed based on the result of the subtraction.

IPC: G01N3/00
Filed: 1985-06-28
Abstract: PURPOSE:To improve the control precision by reading the magnitude of a feedback signal to change the amplification factor of a feedback amplifier so as to obtain an optimum value, and changing a target value signal from a signal generator in the same proportion. CONSTITUTION:A target value signal (a) from a signal generator 1 is read by a set signal reading means A, and a feedback signal (c) from a feedback amplifier 3 is read by a feedback signal reading means B. On the basis of read results of both reading means A and B, a range switching means C changes the amplification factor of the amplifier 3. Since the means C changes the magnitude of the target value signal (a) from the generator 1 in the same proportion simultaneously with the change of the amplification factor of the amplifier 3, the difference signal between signals (a) and (c) is not changed quickly. Since a detection signal (b) of a detector 2 is always amplified by an optimum amplification factor on the way of control and is fed back, the control precision is improved.
