Abstract: A GaAs substrate 200 is rotated, a photosensitive silicone resist 260 is applied on a surface of the GaAs substrate 200 on which an aperture of a hole 310 to be a via hole, and an inside of the hole 310 to be the via hole is filled in with the photosensitive silicone resist 260. Next, the GaAs substrate 200 is further rotated, changing the number of revolutions (rpm), and the photosensitive silicone resist 260 on the GaAs substrate is flattened. Next, a reverse side of the GaAs substrate is grinded, the hole 310 to be the via hole penetrates the GaAs substrate 200 from the surface to the reverse side and the via hole 220 is formed. Next, a reverse side electrode 240 is formed on the reverse side of the GaAs substrate 200. Next, the GaAs sustrate 200 is divided chip by chip and chips are laid on a substrate for assembly 270 via an adhesive metal 280.

Abstract: A liquid crystal display device comprising a signal correcting means for correcting a level of an original image signal to a level with which transmittance in a steady state of the pixel with the original image signal is attained within one frame period, a horizontal driving means for applying a voltage in correspondence with the corrected image signal to liquid crystal, and an illumination device for illuminating the display panel with a plurality of light emitting regions thereof, said light emitting regions sequentially turns on and off in synchronization with the application of the corrected image signal while holding a definite time delay thereto.

Abstract: The present invention is directed to provide a driving circuit and driving method for a LCD having high performance of moving image displaying within few amount of memory and downscaled circuit. In the present invention, a voltage applied to a pixel to drive liquid crystal material in the pixel is determined as a voltage with which the transparency of the pixel at the end of the current field becomes the designated transparency. To determine the voltage, a data table for quick response in which output data is stored in correspondence with some of the possible value of a preceding field image data and some of the possible value of the current field image data is employed, and the output data corresponding to the preceding field image data and the current field image data is determined by the data table through linear interpolation. The voltage corresponding to the output data is applied to the pixel.

Abstract: An auxiliary driving system is provided to ensure that a vehicle equipped with an automatic transmission can be moved or permitted to travel without use of the driving force of the vehicle engine in the event of an emergency. The main driving wheels are normally driven through an engine and an automatic transmission and a pair of auxiliary driving wheels are driven by motors. In a usual state, the motors are used to generate an auxiliary driving force or a creep force in the vehicle. However, if the vehicle engine is stopped due to engine trouble or failure, the motors can be driven based on the amount of accelerator pedal depressed to rotate the auxiliary driving wheels and thereby permit the vehicle to travel. Thus, movement of the vehicle can be easily accommodated in the event of an emergency such as when the vehicle engine has failed.
