IPC: C22C38/00
Filed: 1987-12-28
Abstract: PURPOSE:To obtain a uniform magnetic characteristic in the cross direction of an anisotropic silicon steel sheet by heat-insulating or heating the vicinities of both edges of a billet from the extraction of a slab to the end of the hot rough rolling, and finishing the rough rolling at a specified temp. CONSTITUTION:The silicon steel slab contg., by weight, 0.01-10% C, 2.5-4.0% Si, 0.02-0.10% Mn, and 0.008-0.080% of >=1 kind among the S, Se, Sb, and Mo as an inhibitor is heated to >=1,350 deg.C, and hot-rolled. In this case, the vicinities of both edges of a billet are heat-insulated and heated from the extraction of a slab to the end of hot rolling, and rough rolling is finished at >=1,100 deg.C. The billet is then hot-finish-rolled and then cold-rolled, or the cold rolling including process annealing is applied more than twice. By this method, the magnetic characteristic in the cross direction of a band steel can be uniformized.

Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a radio communication system capable of easily detecting synchronizing signals and simplifying the constitution of a detecting circuit while maintaining detection accuracy in the case of forming the synchronizing signals by OFDM modulation waves. SOLUTION: This radio communication system is constituted of a plurality of radio communication terminals and a radio communication control terminal for controlling radio communications. Among the individual radio communication terminals and the radio communication control terminal, data communications are performed by an OFDM system. The radio control terminals sends the synchronizing signals to the radio communication terminals for respective frames and the individual radio communication terminals receive the synchronizing signals, set a timer by the reception timing and set the timing of transmission and reception with the timer as a reference.  Since the synchronizing signals are formed by using a real part or an imaginary part in the complex modulation data obtained by OFDM modulation of synchronizing codes, the synchronizing signals are detected in a small-scaled and simple correlation computing circuit on the reception side.

Title: Individual difference detecting device for field of synchronous motor and torque detector equipped with same device
Inventor: TAKAKADO YUZO
IPC: H02P21/18
Filed: 1989-12-22
Abstract: PURPOSE:To obtain an individual difference easily by a method wherein a reference voltage, converted from the rotating angle of the field rotor of a synchronous motor, which is detected by a rotating angle detector, is compared with the value of a DC voltage, converted from a no-load AC voltage induced in an armature coil. CONSTITUTION:A control circuit 10 converts AC into 3-phase AC of VVVF and supplies it to a synchronous motor SM1. The rotating angle signal (pulse signal) theta of the field rotor of said motor SM1 is obtained by a rotating angle detector 11 and is converted by a F/V converter 22 to generate a reference voltage VO. When said motor SM1 is replaced due to failure and the like, a switch 23 is closed and a value E, converted from the AC voltage VU of said motor SM1 upon no-load through AC/DC conversion, is compared with the reference voltage VO by a comparator 25 to monitor a difference VO-E through a monitor 26. When the difference VO-E is larger than an allowable value, flux PHI corresponding to the difference is generated by a flux setter 15 and correcting operation is effected by a flux vector operator 16 based on the rotating angle signal theta. According to this method, the individual difference between the new and old synchronous motors SM1 detected easily and a field flux set value is corrected whereby the detecting accuracy of the detecting value of a torque may be prevented.
