Abstract: PURPOSE:To obtain a high coupling efficiency while the positioning accuracy is eased during coupling to an optical fiber by providing a semiconductor layer having a larger refraction index than that of substrate between the active layer and semiconductor substrate and making the thickness maximum on the same center axis as that of the light emitting region. CONSTITUTION:The plane (001) of an InP substrate 21 is etched in circular with the HCl+H3PO4 solution, difference in shape at the cross sections (0-1-1), (01-1) is eased by the melt-back of proper composition and a smooth concave 23 is formed with good reproducibility. Then, the N-InGaAsP 22, N-InP 12, InGaAsP active layer 13, P-InP clad 14, P<+> InGaAsP cap 15 are stacked. The composition of active layer 22 should be selected so that the wavelength of light emitted is longer than the band gap of active layer and it becomes transparent for such wavelength. The electrodes 17, 18 are provided and the light emitted from the restricted region of the active layer 13 is converted to the parallel light beam when curvature of plane 23 of the lens layer 22 is selected adequately and it can be obtainedd from the plane 24 with good efficiency. Thereby, the pertinent diode can be connected to optical fiber with an efficiency near to the theoretical value while easing the aligning accuracy.

Title: Anticorrosiveness detection circuit of liquid containing rust preventives
Inventor: ICHIHARA TAKAYUKI
IPC: G01N17/00
Filed: 1986-06-30
Abstract: PURPOSE:To extend the life of an electrode, by a method wherein a galvano- current is generated in the electrode alone only for a fixed time following the manual operation of a switch to measure the anticorrosiveness and stopped after the fixed time elapses. CONSTITUTION:When a switch 11 is turned ON manually for use, a timer circuit 12 of a current control circuit 9 having a one-shot multivibrator generates an output pulse at a fixed time interval with the rise of an input voltage to turn ON a transistor 10. The time interval of generating the output of the timer circuit 12 ranges from about 0.5-3sec, a necessary time during which a galvano-current begins to flow between a pair of electrodes 1 and 2 immersed in a liquid through the transistor 10 and reaches a normal level. After the time elapses, the timer circuit 12 stops the output to torn OFF the transistor 10 and thus no galvano-current is generated between the electrodes 1 and 2.

Filed: 1986-06-30
Abstract: PURPOSE:To reproduce and display a stable still picture by outputting cutting pulse for synchronization in vertical synchronizing period in delay period and synthesizing the cutting pulse for synchronization to non-delayed vertical synchronizing signals. CONSTITUTION:A monostable multivibrator 9 operates only in a delay period. When a C.Sync signal becomes H level, and a vertical synchronizing period comes, only one pulse signal is outputted as cutting pulse for synchronization corresponding to horizontal synchronizing signal in a delayed vertical synchronizing period. Such operation is not executed in non-delay period. When reproduction is made by television by such frame signals, reproduction and display are executed as before in the field in non-delay period, and reproduction and display are controlled by a vertical synchronizing signal delayed by 0.25H from a non-delay period in the field of a 0.5H delay period. Even when the image of any kind of pattern is reproduced, the vertical oscillation of the image does not occur, and the stable state of display can be obtained.
