Title: Display device and electronic apparatus
Inventor: TOYOSHIMA YOSHIHIKO
IPC: G09G3/36
Filed: 2009-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a display device capable of suppressing ripples without exerting influence on start-up time, and to provide an electronic apparatus.  <P>SOLUTION: In a liquid crystal potential fluctuation preventing circuit 130, the sizes of a first capacitor C120-1 and a second capacitor C120-2 which are smoothing capacitors are reduced by switching in a start-up period, and the sizes are increased in a normal state. Since variation in the potential may be generated by simply performing the switching in the liquid crystal potential fluctuation preventing circuit 130 and a problem may be generated in image display, the second capacitor C120-2 is precharged as a presmoothing capacitor. Consequently, not only both black luminance and white luminance can be optimized, but also the occurrence of flickers can be suppressed and a center value of a common voltage signal can be prevented from being shifted from an optimum value due to use of the display device.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: F02D45/00
Filed: 2009-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To improve the re-startability of an engine by an inexpensive and simple system configuration.  <P>SOLUTION: Whether the engine is re-rotated or not after stoppage is determined. When the engine is determined to be re-rotated after the stoppage, a virtual counter at the forward rotation side and a virtual counter at the reverse rotation side are set up. The former is counted up when a crank signal is inputted on the assumption that the engine after the re-rotation is rotated in the forward rotating direction, and the latter is counted down when the crank signal is inputted on the assumption that the engine after the re-rotation is rotated in the reverse rotating direction. When a cam signal is inputted and the count value of the virtual counter at the forward rotation side indicates that a crank position comes to a predetermined rotating position before a top dead center, the crank position is determined to be moved to a next cylinder. When the count value of the virtual counter at the reverse rotation side indicates that the crank position comes to a predetermined rotation position before the top dead center, the crank position is determined to be returned to a previous cylinder.  <P>COPYRIGHT: (C)2010,JPO&INPIT
