Abstract:
In an image data processing device of the invention, an image memory sequentially stores input image data of multiple frames. A write control module controls a writing operation into the image memory, and a read control module controls a reading operation from the image memory. A driving image data generation module generates the driving image data from read image data sequentially read from the image memory. The driving image data generation module generates the driving image data by replacing at least part of the read image data with regard to selected pixels with mask data. The mask data is set corresponding to a pixel value of the read image data in each of the selected pixels to be replaced with the mask data. This arrangement of the invention effectively reduces blur of a moving image displayed by the image display device, while preventing a significant decrease in luminance level of the displayed image.

Abstract:
A magnetic bearing device comprises a rotary bearing (20) fixed to a rotary shaft (10) and a fixed bearing (30) that supports the rotary bearing (20) in non-contacting fashion. The rotary bearing (20) comprises a permanent magnet of convex cross-section formed with a convex portion towards the thrust direction of the rotary shaft (10). The fixed bearing (30) comprises a permanent magnet of concave cross-section formed with a concave portion capable of fitting the convex portion and formed in the concave portion with a through-hole (35) for insertion of the rotary shaft (10) therethrough. The rotary shaft (10) is supported in non-contacting fashion by the magnetic repulsive force that acts between the rotary bearing (20) and the fixed bearing (30) when the convex portion of the rotary bearing (20) is made to face the concave portion of the fixed bearing (30) so as to fit therein with a minute gap.
Abstract:
A power charging device is provided in which different power sources 12 are used, and if the generating capacity of each of the power sources varies without correlation, the voltage thereof is constantly controlled to be a voltage determined by a charging unit 48, whereby the charging unit 48 can receive uniform voltages. Also, the uniform voltage value is determined based on the difference between the present charging state and the full-charge. Accordingly, charging with an overcurrent and charging beyond capacity can be prevented, thus realizing steady charging.
Abstract:
An image control device for use in a computer system which includes a microprocessor, a bus coupled to the microprocessor, a video memory coupled to the bus and a display device. A write controller is also provided which is coupled to the bus and which controls writing of an image signal into the video memory by supplying a write address to the video memory. The write controller operates to change a range of the write address according to a plurality of write address parameters set by the microprocessor so that a memory area of the video memory into which the image signal is to be written is changed according to the range of the write address. Further, a size of an image represented by the image signal to be written into the video memory is changed. A read controller is also provided and is coupled to the bus for controlling reading of an image signal out of the video memory by supplying a read address to the video memory asynchronously with the writing into the video memory, and in synchronism with the synchronizing signal supplied to the display device along with the image signal read out of the video memory.
