Title: Cylindrical electrophotographic receptor
Inventor: KATAGIRI KAZUHARU
IPC: G03G5/10
Filed: 1982-05-27
Abstract: PURPOSE:To obtain a homogenious photosensitive layer prevented from causing uneven drying during coating a photosensitive drum with a photoconductive coating compsn. and drying it, by selecting the cylindrical substrate so as to set C/rho to a specified value or lower, where C is the heat capacity of the substrate per unit area and rho is its thermal conductivity. CONSTITUTION:The cylindrical substrate is formed by using a material of aluminum or copper so as to control C/rho to <=0.250, where C is heat capacity per unit area (cal/cm<2>) and rho is thermal conductivity (cal/cm.sec. deg.C). This substrate is coated with a liquid coating material contg. a necessary binder, and a liquid dispersion contg. a photoconductive pigment, such as Se, Se-Te, or CdS, or an org. photoconductor, and dried to fabricate an electrophotographic receptor. As a result, the pigment particles, especially, in the charge generating layer of a function-separation type photoreceptor are prevented from coagulating during drying, or a polymer eutectic complex is prevented from causing unevenness in the characteristics, and forming a nonuniform photosensitive layer, and uneven developed images.

Title: Manufacture of polymer film
Inventor: NITTA SHOZO
IPC: B29C47/88
Filed: 1990-04-06
Abstract: PURPOSE:To heighten the productivity of films, while the labor for often replacing electrodes is saved by a method in which ultraviolet rays are radiated on the electrode and its periphery, and the sublimated material on the electrode and its periphery is effectively photolyzed and oxidation-decomposed by the action of said ultraviolet rays and the ozone generated thereby. CONSTITUTION:Static charge is applied onto the surface of the molten film 2 extruded from the nozzle of a die 1 by the action of an electrode 3, and the film is brought in close contact with the surface of a rotary cooling drum 4 by the action of static electricity, and is solidified under cooling. The cooled and solidified film (unoriented film) is transferred to next process. Then, ultraviolet rays is radiated on the electrode and its periphery. This radiation is generally continuous, and the drum side of the electrode is arranged to be irradiated with the ultraviolet rays reflected on the drum surface. A reflecting plate 10 collects the ultraviolet rays near the electrode. Since the ozone generated by the radiation of ultraviolet rays is harmful to human body, whole ejecting part is covered with shields 7, 8, and the ozone sucked by a blower 11 is decomposed in an ozone decomposing device 12.

Title: Permanent magnet material and manufacture thereof
Inventor: YAMAMOTO HITOSHI
IPC: C22C38/00
Filed: 1983-05-25
Abstract: PURPOSE:To improve coercive force and the square-shaped property of a demagnetization curve after a sintering by molding, sintering and age-treating powder having specific grain size consisting of an Fe-B.R alloy kept within a predetermined composition range. CONSTITUTION:Alloy powder having 0.3-80mum mean grain size composed of R (where R is rare-earth elements containing Y) of 8-30% as an atomic percent, B of 2-28% and Fe as the remainder and inevitable impurities is molded, sintered at 900-1,200 deg.C, and thermally treated at a temperature from 350 deg.C to said sintering temperature after sintering. When alloy powder obtained through fine grinding is oxidized remarkably, density after sintering does not increase and magnet characteristics are also low when the mean grain size of alloy powder is less than 0.3mum, and high coercive force is not acquired when mean grain size exceeds 80mum. When the sintering temperature is less than 900 deg.C, sufficient sintering density is not obtained. When it exceeds 1,200 deg.C, residual magnetic flux density lowers and the square-shaped property of a demagnetization curve deteriorates because a sintering body and the orientation of a crystal grain are deformed.
