Abstract: A media drive, a computer system, and a media drive control method, in which insertion/ejection of a removable medium into/from a media drive being in a sleep mode that is a power saving mode of operation can be detected, and the power consumptions of the media drive and host computer can be still more saved. When a CD-ROM drive (2) being in the sleep mode detects a change of status of a CD-ROM, such as insertion or ejection thereof, it notifies a personal computer (1) of the CD-ROM status change by using a hardware interrupt signal without polling. Thus, the status of CD-ROM insertion/ejection into/from the CD-ROM drive (2) can be grasped from the personal computer (1) to place the CD-ROM drive (2) in the sleep mode when the CD-ROM needs not be driven or in a normal mode of operation when it needs to be driven.

Abstract: An electrochromic device includes a layer of electrochromic material, such as tungsten oxide, which is deposited by oblique evaporation at an acute angle of incidence in the range of from 30.degree. to 70.degree. between the normal to the substrate and the direction of the evaporation. Due to the anisotropic topography achieved by the oblique evaporation, the layer of electrochromic material exhibits improved fast response time and long life time of cycling of coloration and bleaching.

Abstract: An electrochromic device includes a layer of electrochromic material, such as tungsten oxide, which is deposited by oblique evaporation at an acute angle of incidence in the range of from 10.degree. to 90.degree. between the normal to the substrate and the direction of the evaporation. Due to the anisotropic topography achieved by the oblique evaporation, the layer of electrochromic material exhibits improved fast response and long life time of cycling of coloration and bleaching.

Abstract: An electrochromic display device having a simplified driving circuit. A colored display is performed by injecting an electric charge into the electrochromic layers of predetermined segments. The electric charge is transferred to the electrochromic layers of the other segments by applying a DC electric field between the predetermined segments and other segments to thereby change the display state.
