Filed: 1979-08-30
Abstract: PURPOSE:To obtain a stable oscillation by forming a reverse conductivity type or semi-insulating layer on the stepwise top of the semiconductor substrate and effectively concentrating a current in an active layer in the vicinity of the step. CONSTITUTION:A P type GaAs 60 is formed on an N type GaAs substrate 2, and with an SiO2 mask is etched, and the step 13 is formed thereon. An N type Ga1-X AlX As 4, a P type GaAs active layer 5, a P type Ga1-XAlXAs  6, and a P type  GaAs 7 are laminated thereon. An opening 62 is perforated at an SiO2 film 63, an  electrode 64 is perforated thereat, and an electrode 65 is fitted therethrough on the substrate 2. According to this configuration, an electric current flows effectively concentrically from the electrode 64 through the rightside of the step of the P type layer  60 to the electrode 65 as designated by an imaginary line 66, and the layer 60 thus  prevents branching of the current. In this manner stable oscillation can be obtained,  the extension of the laser beam can be reduced, and the threshold current can be  lowered. Further, the manufacturing work can be extremely performed satisfactorily.

Title: Liquid crystal display device and driving method therefor
Inventor: YAMAZAKI KATSUNORI
IPC: G09G3/36
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To compensate the effective voltage impressed on each display dot and to eliminate irregularity in display contrast by impressing the voltage which compensates the deformation of the waveform occurring in the scanning voltage waveform or the signal voltage waveform on the group of scanning electrodes based on the display condition of a selected scanning electrode. SOLUTION: The extent of irregularity in the display due to horizontal cobwebbing is determined by the number Z of lighting dots on a selected scanning electrode. A correction circuit 2404 counts the number Z of lighting dots on the scanning electrode to be next selected and outputs an intensity signal 2409 which is activated during the time of the length corresponding to this value Z in synchronization with the signal LP of a control signal 102. A power source circuit 2405 makes a scanning electrode driving power source 2406 whose selection voltage is changed by this intensity signal 2409 and a signal electrode driving power source 107. This time the step of change of the selection voltage is constant and the time of change is dependent on the intensity signal 2409.  Therefore the necessary correction is applied to the selection voltage only for the time of length corresponding to the numerical value Z.

Filed: 1989-04-29
Abstract: PURPOSE:To prolong the service life of a plating soln. by increasing the valence of ions of a material to be plated by oxidation when the ions are generated in the plating soln. by a substitution reaction and bringing the plating soln. into contact with a solid plating metal to feed ions of the metal into the plating soln. CONSTITUTION:When steel is immersed in a copper sulfate plating soln. and the surface of the steel is subjected to substitution plating with copper, metallic copper is put in the plating soln. During plating, Fe<2+> is generated in the plating soln. from the steel by a substitution reaction with copper. This Fe<2+> is oxidized to Fe<3+> by bringing the plating soln. into contact with an oxidizing atmosphere. The Fe<3+>-contg. soln. comes in contact with the metallic copper and causes a reaction represented by a formula 2Fe<3+>+Cu 2Fe<2+>+Cu<2+> to feed Cu<2+> into the plating soln. Cu<2+> can stably be fed at a low cost during substitution plating and the service life of the plating soln. can be prolonged.
