Filed: 1984-02-10
Abstract: PURPOSE:To enable the oscillation of high output pulse laser beams by providing a plurality of laser heads in series between a pair of resonator mirrors and a supersonic Q switch between the opposed end surfaces of each laser rod. CONSTITUTION:Since the first supersonic Q switch 12 and the second one 13 are arranged in series between one end surfaces of respective laser rods 5 of the first laser head 1 and the second laser head 2, each resonator mirror 10 and 11 arranged in opposition to the other end surface of each laser rod 5 can be made much closer to the end surface of the laser rod 5. Therefore, even when the convex lens action of the laser rod 5 increases by increasing inputs to the first and second excitation lamps 6a and 6b, it is difficult that the focal length of a laser beam L becomes equal to a dimension D2; accordingly, high output laser beams L corresponding to inputs can be oscillated.

Abstract: PURPOSE:To transmit character, voice, and still-picture signals through the same circuit and to use a flexible disk device for the recording of composite media in common by storing low-speed data in a subordinate memory, and reading it at a high speed and then recording on a flexible disk. CONSTITUTION:When a still picture is received, a low-speed signal is inputted to an analog type subordinate memory 2 through an input/output terminal 1. The subordinate memory 2 receives it by, for example, two line memories alternately; while one memory is in receiving operation, the other performs high-speed reading operation. An analog signal read out of the subordinate memory 2 is recorded on the flexible disk (FD) 3. On the FD3, one-screen data is all recorded and when this is reproduced and outputted to a TV receiver 5, the one-screen data is read at a high speed of 1/60 second to send FM-modulated data of about 5MHz to a signal conversion part 4. The signal conversion part 4 converts it into a video signal and then outputs the still picture to the TV receiver 5. The use of VTR6 is exactly the same.

Abstract: PURPOSE:To perform automatic collimation even when an objective body is dark without being affected by an observation direction or an observer by condensing the reflected beam from the objective body of the beam emitted from a beam source in a collimation axis direction to a beam receiving surface to calculate the shift quantity thereof from a reference position. CONSTITUTION:A corner cube 54 is mounted to an objective body at the predetermined position thereof. The beam from a beam source 14 becomes a collimation beam through a lens system 12 to be emitted to the front of a telescope 10 and is reflected by the corner cube 54 to pass through the lens system 12 again to enter the telescope 10. The beam condensed by the lens system 12 is reflected by a half mirror 16 to be received on a beam position detection element 18 as a beam spot. The interval of the center axis of the corner cube 54 from a collimation axis A is converted to the shift of a beam spot position G with respect to a reference position P. This shift quantity is calculated by a position shift quantity calculation part and X-axis and Y-axis rotary drive devices are rotationally driven through X-axis and Y-axis control circuits to allow the collimation axis A to coincide with the center of the corner cube 54.
