  • Patent number: 7849724
    Abstract: The outer side of a pair of curved parts 3d of a longitudinal annular blank is pressed and energized towards the curved part 3d of the opponent side with a molding outer die 14 of a shaping device 13 to press and widen each curved part 3d to a large curved part of large curvature radius, and a half-finished article 17 is molded, and thereafter, the half-finished article 17 is pressed and widened by cooperative operation of a finishing inner die of the shaping device and a window part of a perfect circle functioning as an outer die to manufacture a ring-shaped member. Therefore, a yield rate or a percentage of the weight of the ring-shaped member with respect to the weight of the raw material and the yield rate or the percentage of the ring-shaped member with respect to the blank can be improved, and the cost can be reduced.

  • Patent number: 7490503
    Abstract: The method according to the present invention comprises: a first curving step of curving a plate-like metallic blank (1) such that the blank (1) is convexed; a bending step of bending, with the outer peripheral edge portion (1e) of the blank (1) restrained from radially outwardly extending, the resulting arcuate portion (1b) of the curved blank (1) in the direction opposite to the convex direction thereof, so that a boss (6) is formed; and a second curving step of pushing the inner peripheral portion of a flat portion (5) of the blank (1) in the direction opposite to the boss projecting direction. Through the steps above-mentioned, the blank (1) is provided at the center thereof with the case-like boss (6) projecting in one direction from one lateral side of the blank (1) and at the outer periphery thereof with a peripheral wall (7) projecting in the same direction in which the boss (6) projects.

  • Patent number: 7344234
    Abstract: A fluid container, such as, for example, an inkjet print head cartridge, architecture uses a relatively large filter that is located below a negative pressure material chamber and a free ink chamber in a side-by-side relationship. The negative pressure material volume relative to a free ink chamber value can me made to be approximately one to one. Both chambers overlie an ink manifold/delivery port and are separated from the delivery port by a filter. Flow impedance of the cartridge is reduced, as a result, in any orientation of the cartridge. The filter may be separated from, or in contact with a negative pressure material. A cartridge lid is provided with a negative pressure material chamber which is suspended into the cartridge. A negative pressure material having a fiber felt construction is provided.

  • Patent number: 6991325
    Abstract: A port for replenishing ink on the side of a main ink tank advances and the nose or tip end of a main body of a pipe enters an ink replenishing opening on the side of a sub ink tank. When a valve body in the main body of the pipe and a valve on side of the sub ink tank are pressed with each other, a communicating port is opened by the valve body. When the main body of the pipe is further inserted into the ink replenishing opening, the valve is separated from a projection portion of a gasket, and a space therebetween starts to be widened. At this stage, as a lip portion of the gasket is not in contact with an outer peripheral portion of the main body of the pipe, an ink channel is opened to the atmosphere, the ink which is remained in or adhered to the outer peripheral portion of the main body of the pipe or an inside of the ink replenishing opening is absorbed into the sub ink tank dye ti a negative pressure in the sub ink tank.
