Filed: 1993-10-06
Abstract: PURPOSE:To provide a digital circuit device which can secure the agreement in a short time between the phases of external and internal clocks for restart of the internal clock by using a storage and a D/A converter containing a correcting function. CONSTITUTION:The analog voltage that is generated in relation to the phase difference between the internal and external clocks is stored in a storage circuit 10 after the A/D conversion. The signal stored in the circuit 10 is converted into the analog voltage by a D/A converter 120 containing a correcting function. A voltage control oscillating circuit 17 is controlled by the converted analog voltage. If a clock detecting circuit 21 does not detect the coincidence of phases between the internal and external clocks, the converter 120 carries out no correcting operation. Meanwhile the converter 120 corrects the analog voltage when the coincidence of phases is detected between the internal and external clocks.

Abstract: PURPOSE:To perform an etching up to a required depth without inducing a side etching so as to obtain a semiconductor laser excellent in property by a method wherein a layer whose composition turns gradually from that of a clad layer into that of a cap layer is provided between the clad layer and the cap layer. CONSTITUTION:A GaAs buffer 1, an Al0.3Ga0.7As clad layer 2, GaAs active layer 3, and an Al0.3Ga0.7As clad layer 4 are laminated on a substrate. Next, an AlxGa1-xAs layer 5 is formed thereon, where the ingredient (x) changes gradually from 0.3 to 0, and then a GaAs cap layer 6 is overlapped thereon. In this structure, ions are made not to be diffused laterally during ion implantation, so that ion-implantation can be accurately performed up to a certain depth which is determined depending on the accelerating voltage. When etching is performed after the crystallizability is deteriorated through an ion implantation, only the ion implanted region is removed and the etching depth is made uniform, so that a semiconductor laser of a ridge structure can be stably obtained, which is excellent in a property of laterally trapping light rays.

Abstract: PURPOSE:To form a shaft coupling so as to have a large angle of deflection and eccentricity between both shafts, and form the shaft coupling by input and output yokes and a coupling piece by forming the coupling so that lower and turning pairs can be realized between the input and output yokes for connecting the shafts and a connecting piece having two cylindrical curved surfaces.
