Title: Liquid crystal projector
Inventor: IKEDA NAOYUKI
IPC: G02F1/13
Filed: 1994-07-15
Abstract: PURPOSE:To obtain a simple-constitution and high-luminance liquid crystal projector. CONSTITUTION:Light from a light source 7 is made to be the parallel light 3 by a reflector 8. Thereafter, ultraviolet rays and infrared rays are eliminated by a UV/IR cut filter 9. Then, the 15% polarization S component 4 of the parallel light 3 is reflected on the second surface of a first prism 1A set so as to satisfy the angle of polarization and all the polarization P component 5 thereof is transmitted through it after it is transmitted through the first surface of the prism 1A. Besides, the 15% polarization S component 4 of the light transmitted through the prism 1A is reflected on the first surface of a second prism 1B and all the polarization P component thereof is transmitted through it. Then, the light 4+5 is condensed by the second surface of the prism 1B and made incident on the inputting and polarizing plate 11A of a liquid crystal display device 11. As the result, the 72% polarization S component 4 of the whole light is eliminated by the plate 11A and the eliminated polarization S component 4 is radiated. Next, the incident light is modulated by the display device 11 and the modulated light is enlarged and displayed on a screen through a projection lens 2.

Title: Toner supply control method for image forming device
Inventor: ISHIKAWA TOMOJI
IPC: G03G15/00
Filed: 1992-06-23
Abstract: PURPOSE:To remove the density irregularity of an image caused by toner supply by forming a reference pattern between a supply start time and a specified time. CONSTITUTION:The toner supply is started at the point of time when an image area 20 corresponding to a first transfer paper on a photosensitive drum passes a developing part. The interval from the supply start time to time T0 is a required time for the toner to be carried from a toner housing part to the developing part, so that developing is not performed by supplied toner. Then, the reference pattern is formed during the time T0, and the density irregularity occurs under the influence of the supplied toner when the time T0 elapses, but the influence on the image is eliminated by setting a range as a non-image area 21. The image area 22 corresponding to a second transfer paper is made to reach the developing part at the point of time when the density irregularity is removed. Thus the reference pattern PA not affected by the density irregularity is formed and highly accurate and stable toner supply control is performed.
