摘要： A ball-point pen capable of preventing back leakage of ink when the pen is used to write with the ball-point tip above the ink reservoir. The pen has a ball-point tip (15); an ink reservoir (17) and a joint (19) connecting the ink reservoir with the tip for delivering ink to the tip. The joint has a tip-side bore (37a) and reservoir-side bore (33a) connected by a communicating hole (45), for allowing ink to pass from the reservoir-side bore to the tip-side bore. The communicating hole (45) is composed of a large-diameter portion (45b) and a small-diameter portion (45s) connected to the tip-side bore and the reservoir-side bore, respectively, and is eccentric to both bores. A ball 49 having a greater diameter than the bore diameter of the small-diameter portion is disposed to be freely movably in at least a part of a space formed between the rear end of the tip and the large diameter portion when the tip is fitted into the tip-side bore. When the pen is used to write with the tip above the ink reservoir, the ball closes the communicating hole preventing ink from leaking back to the reservoir.

摘要： A direct-feed type writing implement having two ends includes an ink tank and a pair of writing points, arranged at opposite ends of the ink tank. An ink collector is provided for each writing point. An air/liquid exchanger adjusts the internal pressure inside the ink tank by use of capillarity. An ink feeder is provided for each writing point. Each ink feeder includes a center core for feeding ink to the writing point. Air is inhibited from flowing into the ink tank through the ink collector air/liquid exchanger located at one end while the pen is being used for writing at the opposite end.

摘要： A clicking-type writing implement includes a writing element having a writing portion at its distal end, a spring for urging the writing element toward the end, and a clicking rod loosely fitted interlocked with the writing element so as to project from a barrel cylinder. Upon depression of the clicking rod, the engaging rib of a rotor in the barrel cylinder and the engaging bead in the inner cylinder engage with each other, so that the writing element projects and stays projected from a front portion of the barrel cylinder. This clicking-type writing implement also has a so-called double clicking mechanism and a safety mechanism. According to the double clicking mechanism, the clicking rod is projected upon depression and is retracted upon further depression. According to the safety mechanism, when the engaging bead and the engaging rib engage with each other, the projecting state of the writing portion of the writing element is maintained, and when the engaging bead is lifted, the writing element is retracted. No cam surfaces are formed on the inner surface of the barrel cylinder. In the inner cylinder, a cam is formed on the front edge of a cylindrical portion inserted and fixed in the barrel cylinder.

摘要： A ball-point pen of the present invention is provided which includes: a ball-point pen refill being accommodated in the barrel cylinder and having: a tip with a tip ball held at the front end thereof; an ink reservoir which stores low-viscosity oily ink and has an ink follower provided in the rear end of the ink; and a joint disposed between the tip and the ink reservoir. The joint further includes: a valve chamber holding a ball valve in its inside and communicating with the rear end of the tip; and a ball valve seat disposed on the rear side of the valve chamber for the ball valve in order to prevent backward flow of ink. With this configuration, it is possible to provide a ball-point pen which, without need of any cap, can create dense writing traces free from blotting and unevenness even when a low viscosity oily ink is used.

摘要： A ballpoint pen for use with ink having thixotropic (shear viscosity decreasing properties) and a joint for regulating the flow of the ink to the pen's tip through an entrance in the tip. The joint includes a valve chamber which is disposed in an approximately middle portion of the joint with respect to the axial direction thereof for holding a ball therein with play and has a ball seat in the rear part thereof, a cavity in front of the valve chamber and a conduit communicating with an ink reservoir. In this arrangement, in order to allow the ball to fit on the ball seat to prevent ink from flowing backward when the ballpoint pen is oriented upward and in order to ensure an ink flow when oriented downward, the joint portion is constructed such that an axis of path holding the ball valve with play, defined by the top surfaces of the ribs formed on the peripheral wall of the valve chamber, is made eccentric to the axis of the entrance and a channel is provided by the ribs on one side of the valve chamber space for the ink to flow therethrough.

摘要： The increasing ratio of development density to increase in potential difference between a photoreceptor and a development roller differs between the region where the potential difference is small and the region where the potential difference is large. The increasing ratio of development density at the region where the potential difference is small is smaller than the increasing ratio of development density at the region where the potential difference is large. Development is conducted under the developing characteristics in which the upper limit of the development density at the region where the increasing ratio of development density is small is at least 0.3.

摘要： The present invention provides an ink follower for an aqueous ballpoint pen having an ink reservoir for directly preserving an ink, and this ink follower comprises at least a gel-like material having a predominantly viscous response and comprising a less volatile solvent having a viscosity of 5 Pa.multidot.sec or less and a hydrophobic thickening agent, and a solid piece having a specific gravity of 0.80 to 1.10. In addition, the present invention provides a ballpoint pen using this ink follower.The ink follower of the present invention is characterized by using the gel-like material having a high flowability and the solid piece for dispersing and absorbing impact. This ink follower has a strong drop impact resistance, in contrast to a conventional gel-like ink control plug. The aqueous ballpoint pen using this ink follower does not lose its function, even when it is dropped from a shelf at a height of 1.5 m.
