Title: Optical disk and optical disk device
Inventor: SEO HISAFUMI
IPC: G11B7/007
Filed: 1990-05-02
Abstract: PURPOSE:To stably judge the direction or speed of track crossing without depending on variation in light quantity of light beam or on difference in the modulation degree of the reflected signals by adding pits between tracks in the servo area of an optical disk and using the reflected signal from the pits. CONSTITUTION:In the second detected signals obtained from the difference of peak intensity of reflected light from the pits 105 between tracks and clock pits 102, variation of the peak value is canceled as a DC component. This second detected signals surely cross the threshold value for binarization and gives a symmetric waveform to the threshold, so that the signals are surely binarized with a constant duty ratio of 50% for the binarized waveform. Therefore, the second detected signals above described and the binary waveform from the first detected signals indicating the tracking errors are used. By this method, direction and speed of track crossing can be judged stably without being influenced by variation in light quantity of light beam or by difference in the moudlation degree of the reflected signals.

Title: Cleaning device of electrophotographic copying machine
Inventor: TSUKAHARA SUMIO
IPC: G03G21/00
Filed: 1982-07-07
Abstract: PURPOSE:To obtain the scraping effect of blade and the brushing effect of brush by arranging blade and brush on a cylindrical core alternately. CONSTITUTION:An adequate number of elastic blades 4 are projected around the cylindrical core 6a. Brushes 6b are flocked between the blades 4 and the tips of the blades are brushes are at the same circumference. As the number of the blades is greater, the scraping effect is larger and cleaning effect increases, but damage of the photoreceptor surface increases owing to the press-contacting force of the tips, so three - four brushes are suitable. Consequently, the brushing effect of the brushes is obtained in addition to the scraping effect and almost all of toner remaining on the photoreceptor is removed, carrying out extremely excellent cleaning operation.

Abstract: PURPOSE:To attain economization by making it possible to manage with only one photodetector, by synchronizing a wavelength selection switch with a channel switching method. CONSTITUTION:Wavelength selection switch 11 and signal switch 13 are synchronized with each other by synchronizing method 14. Switch 11, capable of tuning to three kind of light wavelengths lambda1, lambda2 and lambda3 transmitted via optical fiber transmission line 5, selects photosignals of respective wavelengths in time-division mode and each selected signal is then led to one photodetector 12 and demodulated into  the original electric signal. Next, switch 13, composed of a general integrated circuit  (e.g. COMS analog switch), separates the output of demodulation 12 into three outputs SIG1, SIG2 and SIG3. At this time, the photosignal of wavelength lambda1, when selected by switch 11, is synchronized with switch 13 to obtain output SIG1 and  SIG2 and SIG3 are similarly obtained. Thus, only one detector is enough at the  reception side and economization is attained.
