Title: Regenerative signal processor
Inventor: UCHIYAMA SHINICHI
IPC: H04N9/88
Filed: 1992-07-08
Abstract: PURPOSE:To prevent the generation of achromatism and hue variation on a television(TV) screen by stopping the comparing operation of a hue comparator by using a drop-out signal in the case of reproducing a guard band part or a tape deteriorated in its recording state. CONSTITUTION:When an output signal from an amplifier 2 is extremely small, an envelope detector 14 judges the signal as a drop-out state and controls a switch circuit 12, which switches the current signal to a signal obtained before 1H to prevent the influence of the extremetely small signal. A synchronizing separator circuit 15 separates a synchronizing signal from a reproduced luminance signal and an HHK circuit 16 removes a vertical synchronizing signal and an equalizing pulse and outputs a signal synchronized with a horizontal synchronizing signal. A phase comparator 17 compares a signal outputted from a frequency divider 20 with the signal outputted from the HHK 16. When the detector 14 detects a drop-out state, the comparing operation is stopped. A phase error signal is smoothed by an LPF 18 to control a VCO 19. Consequently the oscillation frequency of a VCO 21 is locked to a prescribed value.

Abstract: PURPOSE:To enable the oscillation of single lateral mode at a low threshold value by providing a current stricture stripe by the heating with a local heating means. CONSTITUTION:An N-AlxGa1-xAs layer 11, an AlyGa1-yAs layer 12, and a P-AlxGa1-xAs layer 13 are successively crystal-grown on an N<+> GaAs single crystal substrate 10 as a single crystal, and an N-GaAs single crystal layer 26 and a P<+> GaAs polycrystalline layer 25 are grown thereon. Thereafter, a stripe for current stricture is formed by scanning of the grown surface with an Ar laser beam. As a result, the layer 25 gets the specific resistance of a region 24 become smaller than that of a region 26 by about four figures; therefore current stricture is carried out in the region 24. Further, in the layer 26, the P type dopant in the layer 25 is diffused immediately under the part of the layer 25 irradiated with the laser beam, and the layer 26 partly turns to a P-GaAs region 27. Thereby, the region 24 and the layer 13 are electrically connected via region 27; whereas a P-N junction is formed between the layer 13 and the region 26, resulting in current stricture also in the region 27.
