Title: Measuring method of rotation angle
Inventor: KITA YASUO
IPC: G01D5/36
Filed: 1982-09-20
Abstract: PURPOSE:To measure a fine angle of rotation easily and precisely by arranging a substrate where elements A are arrayed at equally (n)-divided positions on the circumference coaxially with a rotating disk where elements B are arrayed at equally (n+m)- divided positions of the circumference of nearly the same diameter, and measuring the relative angle of rotation between the substrate and rotating disk from a shift in the phase of array-order variation in the amount of information occurring to the element A or B. CONSTITUTION:When the rotating disk 20 is irradiated with uniform light from above its top surface side, respective sensors 11 on the substrate 10 photodetect the light through small holes 21 of the rotating disk 20 and their outputs vary in array order as shown by black dots. Namely, the array-order variation of outputs of the photosensors 11 of the substrate 10 shows a two-cycle wave having two maximum and minimum values each. Then, when the rotating disk 20 is rotated slightly, each photosensor varies in the amount of photodetection and the wave shifts in phase as shown by white round marks. Namely, the slight rotation of the rotating disk 20 causes the wave of array- order variation of the photosensors to shift in phase greatly. The outputs of the photosensors 11 are processed statistically to reduce an error of the calculated value of the phase based upon a mechanical error.

Title: Preparation of aromatic hydroxy compound by continuous alkali fusion method
Inventor: MATSUURA AKINORI
IPC: C07C39/04
Filed: 1988-06-30
Abstract: PURPOSE:To economically provide the subject compound in a high conversion rate by continuously supplying an aromatic sulfonic acid alkali metal salt and a caustic alkali to a thin film type evaporator and subsequently carrying out the evaporation of water, a kneading process and a reaction with the evaporator and a biaxial kneader. CONSTITUTION:An aromatic sulfonic acid alkali metal salt and a caustic alkali are mixed in a mixing tank 1 and supplied to a thin film type evaporator 3. The water in the mixture is evaporated in the evaporator 3 and the dried mixture is heated and supplied to a biaxial kneader 4 comprising a combination of a screw and a paddle, followed by kneading at 250-400 deg.C for 5min-5hr. The reaction product is mixed with water in a water-mixing tank 5 and further with an acid in a neutralization tank 6 to deposit the product, followed by subjecting to a step such as the separation of the product with a centrifugal separator 7 to provide the objective compound. The above-mentioned method reduces the loss of energy because of the continuous method and can prevent the heating of a local position. Further, since the control of the reaction is easy, the quality of the product is constant and the quality is highly readily controlled.

Abstract: PURPOSE:To automatically control the thickness in order to improve thickness accuracy, responsibility, and safety, by controlling the thickness if the thickness deviation on the run-out side is larger than the presetted reference deviation, and by controlling the draft percentage if the former is smaller than the latter. CONSTITUTION:The length signal is produced from the pulse generator 10 for measuring the feed- in side length, and is inputted to each of the feed-in side length counters 11, 12, respectively for the thickness controller (AGC) and the draft percentage controller (ARC).
