Title: Protection of motor in low-temperature environment
Inventor: TORII NOBUTOSHI
IPC: H02K11/00
Filed: 1989-07-20
Abstract: PURPOSE:To permit the operation of a conventional motor in a low-temperature environment without any trouble by a method wherein a current, whose polarity is changed in every minute periods upon stopping the driving of the driving motor, is made to flow through the motor. CONSTITUTION:A processor 13a generates a current or an external turbulence, whose polarity is changed in every minute periods, to output it to a servomotor 10 and judges whether the temperature of the windings of the motor has arrived at a set temperature or not. When the same temperature has not arrived at the set temperature, the processor 13a detects the temperature of the windings of the motor again. During this period of time, a current conducted through the motor 10 is changed in every minute periods and, therefore, the motor will never generate rotation and flux in the windings is changed frequently whereby the heat generation of the resistance of the windings is increased. When the temperature of the windings has arrived at the set temperature and the temperature of the servomotor has become a condition suitable for the operation of the same, the processor 13a stops the procession of generating the external turbulence and outputting it to the servomotor, then, outputs an operation available signal to a numerical control device 11. Then, the control device 1 controls the position, speed and torque of the servomotor to drive the same motor.

Title: Optical system for modulating laser beam
Inventor: SAKUMA NOBUO
IPC: G02B27/00
Filed: 1984-09-05
Abstract: PURPOSE:To fix the diameter of a spot of a printer independently of the variation of the beam diameter of a gas laser by arranging the 3rd optical system having positive low refractive power on the beam projection side of the 2nd optical system and changing the distances of the three optical systems. CONSTITUTION:A beam from the gas laser is converged in a modulating element through the 1st optical system 1 having positive power and the modulated beam is made incident upon the 2nd optical system having the same positive power while being diverged, and while decreasing the divergent angle, the light is made incident upon the 3rd optical system 3. The 3rd optical system has positive power lower than that of other optical systems and keeps the ratio of the incident beam diameter to the projected beam diameter at a fixed value by adjusting the distances L2, L3 between the modulating element 4 and the 2nd optical system 2 and between the element 4 and the 3rd optical system 3. Consequently, the spot diameter of the printer can be kept at a fixed value independently of the variation of the beam diameter of the gas laser, and the cost of the optical system can be reduced because the 1st and 2nd optical systems have the same constitution.
