Title: Circuit for driving display element
Inventor: MIYAI HIROSHI
IPC: G09G3/36
Filed: 1992-08-11
Abstract: PURPOSE:To improve responsiveness and to improve the picture quality of an amination picture by adding a component obtained by means of executing weighing to a difference component obtained by means of subtracting an input video signal from the delayed video signal and a frame memory to the delayed video signal. CONSTITUTION:The output SN-1 of a field memory 6 is delayed for one-field as against the input video signal SN. A changed portion is outputted only when the video signal is changed between fields concerning the output (SN-1-SN) of a subtracter 8. Therefore, a value obtained by multiplying it by a weighing coefficient K is added to the output SN-1 of the field memory 6 so that an output video signal SOUT is obtained. In this case, the change of a field cycle in the input video signal is a step-type and SOUT is the signal of a pulse step- type, which is superimposed by a pulse component. Therefore, it is preferable that the output video signal SOUT is supplied to a video AC driving circuit as the video signal.

Title: Laser annealing method
Inventor: SATOU SHIROU
IPC: H01L21/324
Filed: 1983-11-16
Abstract: PURPOSE:To obtain a laser annealing layer having various characteristics far more excellent than conventional by optimally setting the range of an intert gas atmosphere at a time when a compound semiconductor material is irradiated by laser beams. CONSTITUTION:Evaporation is made difficult, diffusion is retarded remarkably and the dissociation of atoms from a crystal surface is also inhibited in a high-pressure atmosphere. Gas partial pressure formed on the surface by evaporating atoms or molecules depends upon the diffusion coefficients of these atmos and molecules in the atmosphere, a coefficient Dh normalized by a coefficient D1 at 1atm depends upon atmosphere pressure, and a reduction rate saturates at 100 atm or higher. The atmosphere at 100atm or higher is necessary and enough conditions in order to obtain an effect by annealing a substance such as GaAs by a laser. Or, the less lattice defects generated on annealing by a laser having a wavelength of 300nm slightly longer than the forbidden band width of GaAs, the more an effect is displayed including defects by the evaporation of As, and the saturation of the reduction of undesired optical density as the center of the optical absorption starts at approximately 100atm and completely saturates at 300atm. Accordingly, thermally unstable GaAs, etc. can be annealed effectively by the laser through treatment in a high-pressure inert gas at saturation pressure or higher.
