IPC: C01F7/448
Filed: 1989-03-14
Abstract: PURPOSE:To produce boehmite having a small grain diameter and a uniform grain size distribution by dispersing aluminum hydroxide in water and treating the dispersion under heated and pressurized conditions in the presence of maleic acid and malic acid. CONSTITUTION:About 2-30 pts.wt. of water is added to one pt.wt. of aluminum hydroxide (about 0.5-50mum grain diameter) and dispersed, and about 2-20wt.%, based on the aluminum hydroxide, maleic acid and/or malic acid are added to the dispersion. The dispersion is treated at about 150-280 deg.C and about 5-65kg/ cm<2>G for 0.5-10hr to form boehmite. The obtained boehmite suspension is conventionally washed with water and dried, and the boehmite having a low content of soda at about <=0.05wt.% with the crystal side of <= about 110Angstrom  and a uniform grain size distribution is obtained.

IPC: G03G15/09
Filed: 1980-05-10
Abstract: PURPOSE:To prevent a chain state of the magnetic powder, by installing a magnetic plate that is magnetized by the magnetic force of a developing roller at the end part of the opening part of a developer tank through which a visible image of a photoreceptor passes and providing a sealing member on the surface opposite to the photoreceptor. CONSTITUTION:A magnetic plate 19 is installed at the end part 3b of the opening part of a developer tank 3 through which a visible image passes after the electrostatic latent image of a photoreceptor 1 is developed. A sealing member 20 composed of a soft porous material is provided on the surface opposite to the photoreceptor 1. The plate 19 is magnetized by the magnetic force of the magnet 2a of a developing roller 2 to increase the magnetic field near the plate 19. Thus the magnetic powder is attracted to the plate 19 and at the same time hidden into the pores of the member 20. Accordingly, the magnetic powder is not substantially put under a chain state and thus does not stick to the surface of the photoreceptor 1.

IPC: H04L7/00
Filed: 1994-03-08
Abstract: PURPOSE:To avoid erroneous synchronization at the time of frame synchronization before a received signal is equalized after frequency selective phasing in broad-band transmission. CONSTITUTION:The received signal is stored in a receiving buffer 2 and the absolute value of a cross-correlation value calculated by a frame synchronous correlator 1 is temporarily stored in a correlation value buffer 3. With a threshold value (a) which is previously set by a correlation peak detector 4, the maximum value and position of the correlation value stored in the correlation value buffer 3 are detected and inputted as maximum value information to a synchronization position decision unit 5. The synchronization position decision unit 5 retrieves the correlation value in a section of several symbols before and after the maximum value; when a 2nd correlation value which is larger than the threshold value (b) obtained by multiplying the maximum value by a specific rate and before the position of the maximum value is detected, the position of the 2nd correlation value is supplied as a synchronization position to the equalizer 6, and when not, the position of the maximum value is supplied as the synchronization position.
