Abstract: PROBLEM TO BE SOLVED: To realize highly accurate and easy magnetization by turning the magnetized part of a resin magnet and detecting the magnetization state based on the rotational angle and a rotational angle detection signal, comparing the rotational angle detection signal with a magnetization state detection signal, and remagnetizing the magnetized part while taking account of the comparison results. SOLUTION: Immediately after magnetization at the outer circumferential part of a resin magnet 9, a magnetization state detector 32 detects the magnetization state and a comparison section compares a magnetization state detection signal with a rotational angle detection signal delivered from an encoder 23. If the magnetization contains an error, difference between the rotational angle detection signal and magnetization state detection signal is determined as a correction amount and outputted to a remagnetization command section. If the magnetization contains no error, a remagnetization command determined by taking account of the correction amount is outputted to a control circuit 31 using a signal from a main field phase detector 33 as a starting point signal when detection of magnetization state is finished for single revolution or remagnetization is executed. The control circuit 31 generates a remagnetization signal and the outer circumferential part of resin magnet 9 is remagnetized.

Abstract: PURPOSE:To execute evaluation without adjustment, by winding a tape-like recording medium to a head drum by a smaller prescribed angle than an actual lap angle, and also, executing the evaluation by executing recording and/or reproduction of a part in the whole track length. CONSTITUTION:A winding angle to a drum 30 of a magnetic tape 13 is not set as a format of a VTR but decreased to about 90 deg.. Also, this winding angle is set so as to go to about half about of an area from the tip part of a video track 65. In such a case, as shown in the figure, the tape is wound more than the tip part by three degrees in considering a margin, and a winding angle of 93 deg. substantially is obtained. It is because that the reproduction of a video signal is taken into consideration, a vertical synchronizing signal and a horizontal synchronizing signal are recorded in the head part of a video track, but in addition, as for waveform per usual drum, a variation element is large in an inlet side, therefore, as for only the inlet side, a tape running system as per standard is used so as to eliminate an unstable factor. In such a way, a tape path adjustment becomes unnecessary.

Abstract: PROBLEM TO BE SOLVED: To efficiently control the auxiliary power without using a mechanical torque sensor and to reduce the weight of the moving device. SOLUTION: A moving device 1 with an auxiliary power source 2 is provided with a speed detection means 3 and an acceleration detection means 4 for detecting the speed and acceleration thereof, and a incline detection means 5 for detecting a inclination of the moving device 1 or the driving road. A control means 6 controls the auxiliary power source 2 by calculating the auxiliary power value based on the detected information by the detection means. The control means 6 calculates a necessary work rate for maintaining the current speed of the moving device 1 and a necessary work rate for accelerating the moving device 1, and then obtains the auxiliary power value by multiplying the sum of both work rates by a coefficient value which is less than 1. Further the control means 6 obtains an operating point as an intersecting point of graph lines based on the auxiliary power value-speed power value-speed characteristic drawing and the work rate-operation speed characteristic drawing of the auxiliary power source 2. Therefore the control means controls driving of the auxiliary power source 2.
