IPC: H01S5/00
Filed: 1990-01-23
Abstract: PURPOSE:To prevent the deterioration of a growing crystal on an etched surface by forming a projecting section by selectively removing an SiNx layer provided on a p-A GaAs layer by etching the SiNx layer to a p-AlGaInP clad layer at a sufficient selection ratio and finishing the etched surface to a mirror surface. CONSTITUTION:An n-AlGaINP lower clad layer 2, GaInP active layer 3, p- APGaInP upper clad layer 4, and p-AlGaAs layer 5 are successively formed on an n-GaAs substrate 1 by an MOCVD method. After an SiNx layer 8 is formed on the layer 5 as a protective layer, the layer 8 is selectively removed by etching. After removing the layer 8, the layer 5 is selectively removed by etching. As a result, the etched surface becomes a mirror surface, because a sufficient selection ratio can be taken. Then an etched section is formed into the layer 4. After the etched section is formed, an n-GaAs blocking layer 6 is formed in the etched section. The surface film 8 is removed and a p-GaAs contact layer 7 is formed on the entire surface of the substrate 1.

Filed: 1995-02-01
Abstract: PURPOSE:To clarify a joint by executing a second correction processing so that visually undesirable gradation and tone do not occur in the boundary area of two areas after picture data A and/or B in the areas where image pickup symmetrical screens continue are first corrected. CONSTITUTION:Picture data A and B obtained by CCD 1 and 2 in the areas where the image pickup symmetrical screens continue are shading-corrected and are coordinate-converted, and a picture shift is corrected so as to set them to be picture data (G1 and G2). Coefficients k1 and k2 whose values linearly change as against picture element data in the area of the overlap part of G1 and G2 for 400 picture elements are multiplied in multipliers ill and 112. The outputs of the multipliers are added in an adder 113 and are set to be picture element data of the overlap part. The values between '0'-'1' in the coefficients k1 and k2 change in accordance with positions in a vertical direction. Thus, the influence of G1(G2) becomes smaller as the value approaches a G2 (G1)-side, and the sense of incompatibility in density distribution at the joint is eliminated.

Title: Interface device for audio communication relay
Inventor: URAJIMIIRU KURATSU
IPC: H04B1/64
Filed: 1990-01-25
Abstract: PURPOSE: To reduce transmission of background noise by detecting the presence of an electric voice signal encoded into an electric communication signal, providing an output of a detection signal and expanding or attenuating the amplitude of the electric communication signal in response to the presence or absence of each detection signal. CONSTITUTION: A frequency forming device 20 is formed of preferably a band pass filter that passes a signal with a frequency band of 200 to 800Hz. An expander 18 provides an attenuation of about 13dB when an output of a preamplifier is sufficiently low. The expander 18 and the frequency forming device 20 attenuates the signal when no voice signal is in existence in a microphone 12 and passes the signal when any voice signal is in existence in the microphone 12. Thus, background noise when the user makes no speech is considerably reduced. An output of the expander 18 increases the gain of the electric signal corresponding to the increased frequency up to a peak of 3kHz and the resulting signal is fed to a 2nd frequency forming device 22.

Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To dispense with the alteration of the design of a power supply circuit and to facilitate ensurance of the lower limit of its regulation range and setting of a high power factor to it, by reducing its ripple voltage components. SOLUTION: An AC voltage is generated in a secondary winding N2 of a converter transformer CVT, by the switching operation of a current-resonance type converter for intermitting the charging current of a smoothing capacitor Ci in order to improve a power factor. This AC voltage is rectified and smoothed to give a DC voltage V3 in the output of a power-factor improving circuit 1. This DC voltage V3 is superimposed on the voltage across both terminals of the smoothing capacitor Ci to feed the obtained voltage to a switching power supply portion 2 as a rectified and smoothed voltage Ei. Thereby, the ripple level of the rectified and smoothed voltage Ei is made equal to the one of a power supply circuit obtained when the power-factor improving circuit 1 is omitted.
