Title: Noise removing circuit to video outline emphasizing signal
Inventor: SAI KAIYOU
IPC: H04N5/14
Filed: 1989-06-09
Abstract: PURPOSE: To improve an S/N ratio by automatically removing a noise signal generated at the time of emphasizing an outline signal for a video input signal. CONSTITUTION: The video input signal is applied in a state where the outline signal and the noise signal are mixed. The outline signal accompanying the noise signal is amplified in a transistor Q1 and a signal in a positive direction is applied to the collector of a transistor Q2 and a signal in a negative direction to the emitter of a transistor Q3. The outline signal accompanying the noise signal is amplified in a transistor Q6 and is applied to FETQ4 and Q5 through a noise removal level adjusting part 15. A signal corresponding to the level of the noise signal accompanied by the outline signal is detected and the noise signal can automatically be removed by the level of the noise signal accompanied by the outline signal for varying voltage required for the conduction of the transistor by using an FET.

Title: Multicolor recorder
Inventor: ITO ISAO
IPC: G03G15/01
Filed: 1985-07-09
Abstract: PURPOSE:To keep always the quality of transferred images well by eliminating the difference in potential level among toner layers corresponding to individual colors at the transfer time to prevent toner from being mixed into a developing means. CONSTITUTION:Since reelectrifiers 5a and 5b which electrostatically charges the surface of a photosensitive drum 1 with prescribed potentials are arranged below developing devices 4a and 4b, the potential of the toner layer developed with toner by each developing means is kept approximately constant in the transfer process and conditions of transfer to a transfer medium are set approximately uniformly. A DC power source 13 is connected to a conductive base body 11 and a DC bias vd of, for example, +1,600V is applied there. Consequently, the attraction based on the DC bias acts upon toner particles held on a latent image carrier to hold toner particles on the latent image carrier more surely. Thus, the toner layer which is used for development beforehand is prevented from peeling and mixing into the succeeding developing means when the latent image corresponding to different color is developed with the toner by the succeeding developing means.
