Title: Recording method of 1-frame picture projected to solid image pickup element
Inventor: ITOU HARUO
IPC: H04N5/335
Filed: 1981-06-15
Abstract: PURPOSE:To obtain a high-contrast picture of one frame, by irradiating the pulse type light to an object to be picked up and receiving a reflected image or a transmitted image of said object at a solid state image pickup element. CONSTITUTION:The pulse type light like the electronic flash light, etc. is irradiated to an object to be picked up. Thus the reflected image or the transmitted image is received at a solid state pickup element of a TV camera. The state of electric charge varies for each element. The adjustment is carried out between a picture of one frame and the irradiation of the pulse type light by securing the coincidence of the relative shifting speed between the solid state pickup element and the object to be picked up and the irradiation of the pulse type light. In such way, the picture of one frame can be obtained with a high contrast.

Abstract: PURPOSE: To provide semiconductor laser wherein a pn junction having a junction surface parallel to the bordery surface between semiconductor layers and holding therebetween an active layer is provided in an active layer region excepting a part directly above the semiconductor substrate, thereby to facilitate the lateral mode control.  
     CONSTITUTION: A P +  region is formed on the surface of an n-type semiconductor substrate 12, and thereafter a groove is formed along the predetermined sripe region. Thereafter, N -  layer 13, n active layer 14, P -  layer 5 and n -  layer 16 are formed,  and a layer 13a excepting the groove 13b of a layer 13 and a part of the active layer  14 are rendered into a P -  type region 22. Then, a P-type region 18 is formed in the  layer 16. By this organization, the P -  active layers as both sides of the stripe region atually produce the reduction of the band gap, and laser oscillation light undergoes loss and a part of light soaking through the layer 13a is aborded undergoes loss. As a result, the horizontal lateral mode is restricted to the stripe part. Further, the absorption coefficient with respect to the laser oscillation light of the layer 13a is great as compared with the layer 13b, and hence the laternal mode control is easily achieved. Accordingly, it is not necessary to extremely strictly the thickness of each of layers 13a, 13b and 14.

Title: Space optical communication device
Inventor: SHIRATAMA KOUICHI
IPC: H04B10/112
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized and inexpensive communication device capable of easily optimizing widening angle of a transmission beam of a selfsation when space optical communication is performed with an opposite terminal by providing a beam converter having a circular opening smaller than the beam diameter of the transmission beam on this side of an optical antenna. SOLUTION: Since the circular opening provided to the beam converter 3 is smaller than the diameter of the transmission beam 11 sent from a light transmission system 4, the beam diameter of the transmission beam 12 transmitting through the circular opening hole is decided by the diameter of the circular opening. In such a case, the widening angle of the transmission beam becomes large instead of that intensity of an optical axial center becomes smaller. That is, when a sufficient light level is secured in terms of line design with the opposite terminal, the fluctuation of the light level is reduced even for a few direction error on this side, and the stabler line is realized. Thus, by selecting the opening diameter of the beam converter 3 so as to become the more optimum widening angle according to the line design, a more optimum space optical communication device is obtained.
