Abstract: PURPOSE:To easily extract a clock from a CMI code with simplified circuit constitution by extracting a clock having a frequency being twice the data frequency from the CMI data, applying 1/2 frequency division to the clock and comparing the phase between the clock subject to 1/2 frequency division and a CMI data trailing detection pulse. CONSTITUTION:A rise/fall differentiation pulse is obtained from a 4Mb/s by a delay circuit 1 and an EOR 2 and a 4MHz clock B is extracted by inputting the differentiation pulse to a tank circuit 3. The 4MHz clock B is given to a D flip-flop 4, where the clock is subject to 1/2 frequency division, and the 1/2 frequency division clock D and its inverted clock are obtained at the same time. The 1/2 frequency division clock D and the falling pulse C are phase- compared by an AND gate 10. When the phase of the both is not coincident, the 1/2 frequency division clock is used as a object clock and extracted as it is, but when not, the object clock is extracted by shifting the phase of the 1/2 frequency division clock by 180 deg..

Abstract: PURPOSE:To make a semiconductor laser long life by partially changing crystal composition so that the luminous output surface of semiconductor crystal performing laser operation and the neighbouring region may have broader band width than luminous energy. CONSTITUTION:In a semiconductor laser element formed a p type Al0.35Ga0.65 AS layer 2 and an n type AlGa0.35GA0.65AS layer 4 by inserting a GaAS active  layer on a GaAS substrate 5, A diffused part 8 is formed as a protective layer  having a wide energy gap by changing the composition of semiconductor crystal  by the use of an ion implantation method to the cleaved end surface or a  method diffusing phosphorus in GaAS. The probability generating a defect in the semiconductor protective layer is decreased by forming such a semiconductor region and the defect is not absorbed to laser light even if the defect exists.  Therefore the defect will not have an influence upon laser operation.
