Title: Manufacture of rare earth permanent magnet
Inventor: SATOU TADAKUNI
IPC: H01F1/08
Filed: 1981-12-23
Abstract: PURPOSE:To improve magnet characteristics as a whole by a method wherein the friction force of formed powder can be reduced and formation density and orientation can be increased without increasing welding pressure and an orientation magnetic field, and furthermore, adverse influence is not given to the magnet characteristics. CONSTITUTION:In the manufacturing method of a rare earth permanent magnet by powder metallurgy processing forming and sintering alloy powder serving rare earth metal (including yttrium) and transition metal as a main component, at least, one kind of saturated fatty acid (CnH2n+1COOH) having n of 3-24, 1.0% or less by wt is added to preformed alloy powder. As the number of carbon of the saturated fatty acid CnH2n+1COOH increases, density G.D. increases  and finally saturates. However, when n is 1 and 2, maximum energy product (BH)max and residual magnetic flux density Br become low as compared with the case when no addition is made. When n is 3, (BH)max and Br rapidly increase and raises with an increase in n and high values are maintained. When n is 18 or more, (BH)max and Br slightly decreases. Therefore, addition of saturated fatty acid at n of 3-24 improves Br, (BH)max, and G.D.

Title: Refuse bin
Inventor: SAKAGAMI MASATOSHI
IPC: B65F1/06
Filed: 1994-08-08
Abstract: PURPOSE:To prevent at least vertically falling refuse from entering the gap between a refuse bin and a bag by constructing the refuse bin so that the gap between an outer tube and an inner tube, and the upper end of a side wall part of the inner tube cannot be seen from an opening part of a crown part when viewed from above vertically downward, when the inner tube and the outer tube of the refuse bin are assembled. CONSTITUTION:The outside diameter of a crown member 33 is the same as that of an outer tube 3, and the inside diameter is concentric with the outside diameter of the outer tube and smaller than the inside diameter of a side wall 11. Because of the dimentional difference between the inside diameter of the crown member and the inside diameter of the side wall of the inner tube, the gap between the inner tube 1 and the outer tube 3, and the upper end or cut end wall 15 of the inner tube 1 cannot be seen from a refuse dumping port when viewed from above vertically downward even when the inner tube 1 is shifted to any part of the side wall 31 of the outer tube 3. The height of the bottom face of the crown member 33 for the outer tube 3 is higher than the height of the upper end of the side wall 11 of the inner tube 1, and the bottom part 32 of the outer tube 3 is positioned close to the floor, that is, a peripheral end part 21 and the inner tube 1 cannot be seen. When viewed from above vertically downward, the gap between the outer tube 3 and the inner tube 1, and the cut end wall 15 of the inner tube 1 cannot be seen. Thus, the falling refuse is prevented from entering the gap when it is dumped.

Title: Image forming method
Inventor: YAMADA TAKANOBU
IPC: G03G13/00
Filed: 1986-09-04
Abstract: PURPOSE:To simultaneously form image of two kinds of densities by supplying a toner to a first and a second electrostatic latent images, respectively and forming a first toner image of a light color and a second toner image of a dark color. CONSTITUTION:For instance, with respect to a developing bias voltage +350V applied to a developing sleeve 71, the surface potential of the first image part and the surface potential of the second image part are set to +200V, and about '0'V, respectively. As a result, the second toner of the straight polarity, which is held in the developing sleeve 71 adheres electrostatically to the first and the second image parts. Also, its quantity is smaller in the first image part in which a potential difference to the developing bias voltage is small, and larger in the second image part whose potential is lower than that of the first image part. Accordingly, the toner density of the first image part which is transferred to transfer paper P in a transfer area S is lighter and lower than that of the second image part. In this way, images of a high density and a low density can be formed simultaneously.

Title: Magnet device for color cathode-ray tube
Inventor: TSUKII NORIO
IPC: H01J29/54
Filed: 1988-08-24
Abstract: PURPOSE:To position a plurality of magnetic pole pieces near a neck part tube wall by coupling the portion of a magnetic pole holder between magnetic pole pieces to a neck part mounting body and so forming the part of the neck mounting body corresponding to the magnetic pole pieces as to have a diameter smaller than a part to be coupled to the holder. CONSTITUTION:When a magnetic pole holder 9 is pushed from the edge of a neck part mounting body 4, a claw part 4b is defected inward due to the coupling part 9b of the holder 9. Also when this coupling part 9b strides over the claw part 4b and the claw part 4b comes to be located at a groove part 9a, the claw part 4b is reset due to the elasticity thereof and the magnetic pole holder 9 is thereby mounted to the neck part mounting body 4. As aforementioned, a portion between the magnetic pole pieces 8A to 8H of the holder 9 is coupled to the neck mounting body 4 and, therefore, an insulation part 4c corresponding to he magnetic pole pieces 8A to 8H of the neck mounting body 4 has no mounting function. It follows, therefore, that the outer diameter dphi of the insulation part 4 can be so formed as to be smaller than the coupling outer diameter Dphi of the neck mounting body 4, or the insulation part 4c can be eliminated.

Title: Developing device and process cartridge
Inventor: NUMAGAMI ATSUSHI
IPC: G03G21/18
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent damage such as the deformation of a toner container or the tear and the peeling of a toner seal from occurring caused by the fluctuation of pressure in the toner container by providing a device with a protection member covering a filter closing a ventilation hole formed at the toner container from the outside of the toner container. SOLUTION: In order to form recessed surfaces 101 and 102, the walls of the parts of the recessed surfaces 101 and 102 are formed so as to project from the surface of an upper frame body 11a by giving identical thickness to the surface of the frame body 11a. The depth of the wide recessed surface 102 is set to be almost equal to the thickness of a seal member 110 being as the protection member having even a function protecting the filter 100. Then, a small aperture 103 being as the ventilation hole through which 11A communicate with each other is formed at the narrow recessed surface 102. The filter 100 is arranged so as to close the aperture 103 of the toner upper frame body 11a.  Thus, since the increase or the decrease of the pressure in a toner frame body 11 can be suppressed, the filter is prevented from being damaged and toner is prevented from leaking caused by the damage of the filter 100.

Filed: 1985-09-24
Abstract: PURPOSE:To protect a photographic lens when the camera is not used by closing a lens protection cover according to a film rewinding signal generated in response to the prescribed or manual operation of the camera. CONSTITUTION:When all frames of a film are exposed and the film is not drawn out any more, a film end detection signal generating part detects that and a lens barrel block 8 moves to a lens storage position. At this time, the start position of a downward slanting surface 25c is positioned very closely to a rod 28b and when a cam member 11 begins to further rotate, the rod 28b starts moving down along the slanting surface 25c with the spring force of a spring 29, and consequently a lever 28 rotates clockwise. A driving ring 5 also rotates counterclockwise associatively and lever covers 4a and 4b are closed.
