IPC: G03G21/00
Filed: 1983-10-19
Abstract: PURPOSE:To clean completely residual toner on a photosensitive body, and to prevent an image from being stained and to improve the picture quality by providing a grounding means between a blade or blade holder and a grounded body, and discharging the static electricity on the blade. CONSTITUTION:A conductive coupling member 28 is fitted on a conductive pin 12 provided to the blade holder, and its other end part is fitted onto a bush provided on the support shaft 3 of a photosensitive body 2. The pin 12 conducts to the support shaft 3, which is grounded through the frame 1, so the blade and blade holder are grounded. Therefore, the static electricity generated on the blade owing to the frictional contact with the photosensitive body 2 is discharged to the support shaft 3 to eliminate completely black stripes appearing on the image, thereby preventing an error in copying and improving the copy quality.

Title: Main spectrum extractor for sound analyzer
Inventor: KITAGAWA HIROSHI
IPC: G10L25/00
Filed: 1983-10-19
Abstract: PURPOSE:To achieve a sound synthesization with limited noise avoiding extreme change in the frequency by memorizing frequency extracted from the main spectrum into a reference frequency memory provided in the main spectrum extractor to set the subsequent extraction frequency. CONSTITUTION:Frequency spectrum of input voice from an analyzer is stored into a spectrum envelope memory 201 of the main spectrum extractor 200'. Peak values at the crest of the spectrum envelope in the memory content are read out with a secondary peak level detection circuit 202 by N pieces sequentially from the maximum and hence, a frequency extraction circuit extracts the frequency at the peak point. The results of the extraction are fed to a synthesizer together with the results of the extraction with an amplitude extraction circuit 203, a frequency extraction circuit 204 and a phase extraction circuit 205 while being stored into a reference frequency memory 210 to be the reference for setting frequency through the memory 201 with a side peak detection circuit 211 when the subsequent peak point is extracted. Thus, main spectrum is extracted without extreme change in the frequency thereby accomplishing a voice synthesization based on a voice analysis with limited noise.
