摘要： In order to improve the adhesion property of an electrical steel sheet with no film of inorganic mineral matter on its surface, especially with respect to a tension-imparting insulating film, anodic electrolysis in an aqueous solution of silicate is carried out before insulating film formation to form a silicic film excellent in adhesion property with respect to the insulating film in a thin and strongly attached condition on the steel sheet surface. By this, a tension-imparting insulating film can be formed on a grain-oriented electrical steel sheet with excellent adhesion property to reduce the iron loss of the oriented electrical steel sheet. Also in the case of an insulating film that is not of the tension-imparting type, enhancement of film heat resistance and improvement of insulating property by increasing a film thickness are possible.

摘要： A method, system and computer-based product adjusts a synchronous operation of beams in scanning direction of a multiple beam optical system. Alternatively emitted, a standard beam and one of plural beams are scanned across an image forming body in respective scanning operations. During each scanning operation, a time interval (T1) is measured from when the standard beam is detected by a detector to when the other beam is detected. Similarly, another time interval (T2) is measured from between when the other beam is detected to when the standard beam is detected. Time intervals T1 and T2 are compared so as to distinguish the arrival order of beams and then the beams are adjusted at the source so as to compensate for a detected incorrect order or misalignment of the beams.
