Abstract: PURPOSE:To make it possible to oscillate in the narrow width of a spectral line, by determining the periods of first and second diffraction gratings so that the Bragg wavelength of the second diffraction grating is longer than the oscillating wavelength determined by the period of the first diffraction grating. CONSTITUTION:The folloing parts are provided on a semiconductor substrate: an active layer 4, which emits light; an active region 1, which has a diffraction grating 11 in the vicinity of the active layer 4; a light guide layer 2, which guides the light emitted from the active layer 4, along the extending line of the active layer 4; and a distribution reflecting region 2, which has a second diffraction grating 12 along the light guide layer 2. A means for injecting a current into the active layer is provided in the active region 1. The periods of the first and second diffraction gratings 11 and 12 are determined so that the Bragg wavelength of the second diffraction grating 12 is longer than the oscillating wavelength determined by the period of the first diffraction grating 11. Thus the semiconductor laser, which is oscillated at a single wavelength in the narrow width of a spectral line, is obtained without yielding mode jumps.

Abstract: PURPOSE:To ensure the optimum control state even under the working of a process, by using the sample value control constant which is obtained by switching the sample value PID system to the sample value on/off system when the process dynamic properties are identified under the control. CONSTITUTION:In the normal mode, the output signal of a sample value PID control arithmetic part 5 passes through a switch part 7 and is fed to a sample holding part 2. Thus the operation signal is obtained to give the control to a process 1. While in the identification mode, the part 7 is switched to the side of a sample value on/off control arithmetic part 6. Then the operation signal of the process 1 is obtained by supplying the output signal to the part 2. Thus the sample on/off control is carried out in the identification mode, and the sample value PID constant Kc, Ti and Td are calculated from the output of the part 6 or 7 and the process signal y(t) via a sampler 8. This operation is performed at a pulse transmission function identifying part 9, a transmission function arithmetic part 10 and a sample value control constant arithmetic part 11.
