Title: Laser functional device
Inventor: INABA FUMIO
IPC: H01S3/10
Filed: 1984-06-18
Abstract: PURPOSE:To construct the titled device so as to put the oscillated output light of a laser oscillator in a bi-stable state, and to enable easy realization of its IC- processing by a method wherein the action of photo intense modulation of a photo intense modulation element is controlled by feeding electrical signals back to the drive power source. CONSTITUTION:Output lights 6 and 6' obtained via both ends of the laser resonator, i.e. reflection mirrors 3 and 3', respectively, have power Po equal to each other. When the intensity of the detection current 8 of a photo detector 7 to detect one output light 6 is Je, a fixed relation exists between the photo output Po and the intensity Je of the detection current 8. Next, an electronic circuit 9 amplifies the current 8 to a required intensity on the basis of said intensity Je, otherwise, the output current forming a fixed relation dependent on the intensity Je is generated. When the intensity of the output current 10 is Jf, this current 10 controls by feedback the action of a photo intensity modulator 4 according to the intensity Jf via drive power source 5. This enables the output light power Po of the laser device to offer the bi-stable characteristic.

Filed: 1978-10-11
Abstract: PURPOSE: To perform lens driving of less mechanically undue motion by providing a speed control circuit, etc. and decelerating the converging speed thereof always at a fixed speed even if the moving speed is set at an arbitrary value.  
     CONSTITUTION: The position detecting signal LD from a potentiometer 14 and the moving position command signal LI from a zoom demand 16 are applied to a control circuit 15. According to the level difference of the abovementioned both signals LD and LI, the speed command signal SI is fetched out from the abovementioned control circuit 15. The speed control of a servo motor 12 is accomplished by this speed command signal SI. Here, the lens moves at a fixed speed S 1  until the differential signal of the position detecting signal LD and moving position command signal LI lowers down to the specified level or under, e.g., like the alternate long and short dashes lines, after which it moves at the speed corresponding to the differential signal until it arrives at the B point from the C 1  point. Since the converging speed is decelerated at a constant speed in this way irrespective of the magnitude of the moving speed, the lens driving of less undue motion may be accomplished.
