Patent JP-S61221808-A (JP)
Title: Servo circuit
Inventor: NISHIKAWA KIYOAKI
IPC: H02P29/00
Filed: 1985-03-27
Abstract: PURPOSE:To control a motor with a simple circuit by providing a control circuit which produces the drive signal to control the start-stop of the motor after calculating the amount of displacement, the revolving direction and the revolving speed of the motor from the output of a D/A converting means. CONSTITUTION:When a motor 3 is driven, a transducer 5 for generation of phase modulated waves delivers a phase modulated wave E in response to the angle displacement of the motor 3. An exclusive OR circuit 6 delivers a pulse having a duty ratio corresponding to the phase difference between a carrier wave F and the wave E. This pulse is integrated by an integration circuit 7 and turned into an analog position signal G. A microprocessor 1 calculates the amount of revolving displacement, the revolving direction and the revolving speed of the motor 3 by the signal G and sets successively the optimum speed in response to the remaining amount of displacement up to the target position. This set speed is compared with the actual speed of the motor 3. Based on the difference obtained from said comparison, the processor 1 produces a pulse width modulated drive signal B to drive the motor 3 via a motor drive circuit 2 and controls the speed of the motor up to a place near the target position.

Title: Mask provided with water absorptive function
Inventor: KONUKI OSAMU
IPC: A62B18/02
Filed: 1988-03-18
Abstract: PURPOSE:To absorb moisture content due to exhalation without entailing any drop in permeability as well as to eliminate an unpleasant feeling during application by attaching a water absorbent fiber or a water absorbent resin filter to the inside. CONSTITUTION:A water absorbent fiber-make filter 2 is attached to the inside of a simple dust mask 1, and air at the outside passes through this simple dust mask 1 and the water absorbent fiber filter 2 and used for respiration. Since moisture content contained in exhalation is absorbed by this filter 2 and preserved therein, the inside of the mask 1 is in no case wetted by the moisture content even if it is used for hours. In addition, since the moisture content in the respiration exists on the surface of a water absorbent fine, permeability is sufficiently securable, while there is a filter effect to arrest water soluble harmful smoke of the like being contained in the respiration. Consequently, even if this mask is used for hours, a user is released from any unpleasant feeling due to respiratory water content and, what is more, the arresting efficiency of dust is improvable in keeping the permeability maintained intact.
