Abstract: PROBLEM TO BE SOLVED: To prevent calcium salt, etc. from depositing and sticking on a strand guide and to solve cutting of a strand caused by this by using a cooling water processed by a magnetic water processing tool in a method for granulation of a synthetic resin in which the strand is cooled with cooling water and is cut into a pellet-like shape. SOLUTION: In a method for granulation of a synthetic resin wherein a molten polymer is extruded into a strand condition and is cooled by using cooling water and is cut into a pellet-like shape, a cooling water processed by a magnetic type water processing tool. Both collision and concn. of positive and negative ions occur thereby simultaneously at the central part of a pipe in the case of polarization of the ions and dissolved ions are bonded together to accelerate crystallization of the ions in water. Namely, crystallization ordinarily occurs on a strand guide and is generated as a scale but in this case, extremely fine crystals are formed in water and are carried with water.  Metal ions become powdery when they are crystallized in water by passing the magnetic water processing tool through a magnetic field of about 6,000 gauss and adhesive strength thereof becomes weak to suppress adhesion of the scale.

IPC: C23F4/00
Filed: 1992-09-07
Abstract: PURPOSE:To reduce F atoms remaining on the surface of a semiconductor substrate, to increase H atoms and to increase a surface inactivation effect by a method wherein high-temperature H2O gas is used in a treatment in the removal of an oxide film on the surface of the semiconductor substrate by using an HF-based gas or solution and in a surface inactivation treatment.

Title: Data error detecting circuit and data rewriting circuit for winder mechanical loss compensation torque
Inventor: TSUJIOKA HIROSHI
IPC: B65H63/00
Filed: 1990-09-07
Abstract: PURPOSE:To alarm abnormality of mechanical compensation torque by exerting a total value of tension torque responding to a tension applied on a long material during winding of the long material, acceleration deceleration torque necessary to the change of the running speed of the long material, and mechanical loss compensation torque obtained by bringing a winder into a non-load operation state on a winding motor. CONSTITUTION:A fact that an output of a deviation value computer 12 is not zero during running of a long material 2 at a constant speed, i.e., regardless of acceleration and deceleration being zero is caused by a fact that mechanical loss compensation torque stored in a memory 41 is different from actual mechanical loss torque. Therefore, when it is detected that acceleration and deceleration are neither zero and a deviation between a tension actual value T and a tension target value T* is nor zero, an alarm for a fact that there is an error in mechanical loss compensation torque stored in the memory 41 is reported from an output terminal 28. When the absolute value of the deviation value is higher than some extent regardless of acceleration and deceleration being zero, a mechanical compensation torque value stored in the memory is rewritten.

Title: Image pickup type boundary detector
Inventor: HAYASHI MASAHIKO
IPC: G06T7/60
Filed: 1987-09-21
Abstract: PURPOSE:To attain proper binarization without changing the setting of a threshold level even when the size of a found differential value is changed by detecting the maximum value of the differential values and correcting respective differential values corresponding to respective picture elements so as to increase them in accordance with the decrement of the maximum value. CONSTITUTION:Since the maximum value of differential values is reduced when the contrast between an unprocessed working area and a processed working area is low, and is increased in accordance with the increment of the contrast, respective differential values of respective picture elements are corrected so as to be increased in accordance with the decrement of the maximum value, so that even when the differential value is changed from the proper range for the set threshold level, the value can be corrected so as to be a value corresponding to the proper range for the set threshold level. Even if the contrast between the unprocessed working area and the processed working area is changed due to variation in the state of the working area or weather, proper binarization can be attained without changing the setting of the threshold level independently of the size of the differential value.
