Abstract: PURPOSE:To easily and properly improve the erosion resistance of the required portion of a propeller by using a mold made of a good thermal conductivity only for the aforesaid portion, and thereby applying quenching treatment after the solidification of nickel-aluminum bronze casting. CONSTITUTION:Nickel-aluminum-bronze casting is conventionally improved for erosion resistance by reheating the whole of the casting at a normal temperature after a casting process, thereby carrying out thermal treatment for hardening and annealing the casting to increase the hardness and erosion resistance thereof. In the case of a large-sized and heavy weight product having a curved surface like a marine propeller for a large ship 1, however, the aforesaid thermal treatment causes the deformation of the casting after the reheating process. In order to settle such a problem, a mold comprising a good thermal conductivity material, for example, a steel particle casting mold 4 is used instead of a sand mold 5 for casting only the blade tip 3 of the propeller 1. According to the aforesaid process, quenching treatment applies at a cooling speed equal to or above an air cooling speed after the solidification of the casting, thereby easily and properly improving the erosion resistance of the blade tip 3 of the propeller 1.

Title: Method for development
Inventor: KITAJIMA NOBUO
IPC: G03G15/09
Filed: 1980-10-15
Abstract: PURPOSE:To realize a development process by which a high-quality picture is formed regardless of a low level of the latent image potential, by giving a relative shift to a magnetic material unified with a magnet with a close distance to an image holding member and carrying out the development with use of a developer held by the magnetic matter. CONSTITUTION:The electric resistance between an isolated electric conductor 4 and a light tramsimissive electrode 5 varies by the exposure given from a supporter 2 via a photoconductive layer 3; while the electric resistance has no change between the conductor 4 and a light shielding electrode 6. Thus a partial pressure image is formed at an image holding member 1 containing a protector 8. Then a relative shift is given to the member 1 and a developer consisting of a magnet 9, and a magnetic member 10 holding a magnetic toner 11 with an extremely close distance to the member 1. As a result, the toner 11 attaches in good conditions to the member 1 by the electrostatic force produced by a latent image. In such process, a high quality picture is ensured although the latent image potential is set at a low level of voltage.

Filed: 1984-07-12
Abstract: PURPOSE:To sustain the friction force of a paper feed means composed of a friction-feed belt, etc. over a long time period to surely feed papers, by making an adhesive member into close contact with the paper feed means to remove paper powder adhered to the paper feed means. CONSTITUTION:Copying papers stored in a tray 1 are taken out one by one by means of a friction-feed belt 3 which is rotated from a paper stack 2 in the direction of the arrow 13. At this stage a retard roller 4 loosens the papers so that the papers are surely fed one by one. These papers are fed into the next stage such as, for example, a photosensitive drum device or the like by means of a feed roller 5. When copying papers onto which paper powder produced upon cutting is attached are taken out from the paper stack 2 by means of the belt 3, the powder adheres to the belt 3 which therefore gradually lowers its friction coefficient and finally becomes impossible to take out papers. In view of such a trend, an adhesive tape 10 is made into close contact with the belt 13 to remove and transfer the paper powder on the belt 13 with the use of adhesion of the tape onto the surface of the tape.
