Title: Image forming device
Inventor: HOSAKA AKIHITO
IPC: G03G21/14
Filed: 1985-11-06
Abstract: PURPOSE:To prevent a carrier from sticking to a photosensitive body and damaging the photosensitive body while a device is held stopped by turning off primary electrostatic charge and impressing the DC component of a developing bias to the photosensitive body before the passage of the part of the photosensitive body which is not subjected to the primary electrostatic charge through a developing device. CONSTITUTION:The primary electrostatic charge is turned off and the DC component of the developing bias is turned off upon arrival of the region where the surface potential of the photosensitive drum 3 attains V1 by receiving electrostatic charge for transfer at the developing position; therefore, the DC component of the developing bias is kept impressed to the drum 3 until the region thereof subjected to the primary electrostatic charge passes the developing position. The potential difference between the surface potential of the drum 3 and the surface potential of the developing sleeve of the developing device is prevented from attaining the value at which the carrier charged to a positive polarity in the developer sticks to the photosensitive drum or above. The sticking of the carrier onto the drum 3 is thus prevented.

Title: Reflection type liquid crystal display device
Inventor: MIZUNUMA MASAYA
IPC: G02F1/139
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To make constitution simpler and brighter than heretofore and to enable the device usable even in a dark place by providing the device with a scattering polarizing plate which is arranged behind liquid crystals, is transparent to the polarization component in one direction of light and scatters and reflects the polarization component in a direction perpendicular to this one direction to a direction reverse from the progression direction of the light. SOLUTION: The polarized light 101 parallel with the plate of page space is absorbed by the guest-host type liquid crystals 7 in the state that voltage is not impressed between transparent electrodes 10 and 10'. On the other hand, the polarizing plate 102 perpendicular to the plane of page space transmits the quest-host type liquid crystals 7 and further transmits the scattering polarizing plate 11 as well. This light is absorbed by a light absorption plate 12. Then, the light does not reach an observer and the display is black. In the state that the voltage is impressed between the transparent electrodes 10 and 10', the polarized light 102 perpendicular to the plane of page space transmits the scattering polarizing plate 11 and is absorbed by the light absorption plate 12 like the state that the voltage is off.  Then, the polarized light 101 parallel to the plane of page space scattered by the scattering polarizing plate 11 reaches the observer and the display is white.
