Even when the moving speed of the recording head 5 is changed in this way, since the length of the time difference of the dot output signal is adjusted correspondingly to the moving speed, the relation in position of print dots on the recording sheet is kept always constant thereby preventing the deterioration in the print quality due to the speed change.

Abstract: PURPOSE:To enable automatic switching to AC mode and DC mode by connecting a self-moving control circuit for driving a motor for self-moving through a rectifier circuit to a tap of the field coil of a motor fan and connecting a DC power source through the normally closed contact of an AC relay to the tap. CONSTITUTION:When AC power is inputted, an exciting coil 11 is excited to close a contact 12 and to open a contact 16. Consequently, a motor fan 13 is operated with AC input power. Upon interruption of AC input, the exciting coil 11 is de-energized to open the contact 12 and to close the contact 16. Consequently, the motor fan 13 is provided with power from a secondary battery 17. Since a self-moving control circuit 19 is connected through a rectifier circuit 18 between tap lead-out of the field coil 13a of the motor fan 13, a motor 20 for self-moving can be driven in both AC mode and DC mode.

Title: Phase detecting coil for dc servo motor
Inventor: MIYAUCHI NORIO
IPC: H02K29/14
Filed: 1984-07-30
Abstract: PURPOSE:To remove the variation in the output by reducing the effective coil area in the lead of a lead wire of an FG coil pattern and increasing the effective coil area at the folding portion of the pattern. CONSTITUTION:A narrow region 300 intruded into the inside of the lead of a lead wire A is formed, with the result that the effective coil area of the lead wire A becomes smaller than that of the other portion. Thus, a magnetic flux crossing number is reduced to resultantly reduce the induced voltage output value. An enlarged portion 400 is formed at the coil toward the outer peripheral side at the folded portion B to increase the effective coil area of the folded portion B and to increase the magnetic flux crossing number. Accordingly, the induced voltage output of the folded portion B also increases. Thus, compensating action is generated to remove the variation in the frequency.
