Patent JP-2003108065-A (JP)
Title: Active matrix type display device and its driving method
Inventor: TSUGE HITOSHI
IPC: H05B44/00
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce display irregularity due to dullness in current waveforms caused by a stray capacitance of a source signal line of a current driven active matrix type display device. SOLUTION: The value of a current which flows in the source signal line is increased in order to make electric charges accumulated in stray capacitance correspond to display gradation quickly. To accomplish the above, the channel size of a driving transistor of each pixel is changed for a case in which the transistor is connected to the source signal line and for a case in which the transistor is connected to a display element. For example, the current value which is to be applied to the source signal line is made ten times larger in a two type panel so that driving is conducted in a 75 μ second horizontal scanning interval even though the stray capacitance of the source signal line is twenty-five pF. Moreover, a gradation vs. luminance characteristic is improved by using the fact that the time required for the change is different for every gradation.

Title: Method for detecting change in technical system due to ageing, device therefor, program, storage medium, detection system, and device for determining abrasion model
Inventor: GRIMM WOLFGANG
IPC: G01M99/00
Filed: 2001-10-01
Abstract: PROBLEM TO BE SOLVED: To predict a change in a technical system due to its ageing in multidimensionality, and adequately ensure convergence.

Title: Image pickup device
Inventor: KOSUGE KATSUYA
IPC: H04N3/14
Filed: 2001-10-03
Abstract: PROBLEM TO BE SOLVED: To quickly write control data on an EEPROM when shipping from a factory, or the like. SOLUTION: In an image pickup device, after powered on, a data value of a specific address for use in an initial reference within an EEPROM is set to a value indicating a write mode, an initial set value of control data described in an operating program is stored in the EEPROM, and also the data value of this specific address is set as a value other than that indicating the write mode. For this reason, switching between a normal operating mode and the operating mode of writing the initial set value is not performed when the start of a control program, but the switching can be performed at an initial processing started after powered on.  Accordingly, if the data value of the specific address for use in the initial reference in the EEPROM by use of any means is turned on again for writing, after powered on and before operating the camera control program, a transfer can be made to the write mode.
