摘要： A pen point made of an inorganic material, which is free of restrictions on the viscosity of ink and the particle diameter of pigment to be used, excellent in buckling strength, highly resistant to wear and solvent, and capable of mass production at low cost. It has such a structure that a mixture of fine particles of metal or ceramic with a binder is extruded, degreased, and sintered to form a continuous piece having a uniform cross-section and provided with through holes of various profiles along its axis permitting capillary movement of ink and grooves for ink passage with one end thereof forming a part of the surface sharpened at its tip to be used mainly for writing.

摘要： (57) The structure of a ball-point pen tip comprising the combination of a ball holding tube made of any material selected from metals such as stainless steel, plastics such as super- engineering plastics or ceramics, a ball retaining core and a ball, and satisfying various requirements for ball-point pens using a low-viscosity ink, such as drain-back resistance of ink, smooth beginning of writing, returnability of ink, high-speed ,writability, stable ink supply smooth ball rotation and high productivity. The ball retaining core (2) is fixed within the ball holding tube (1) and the ball (4) is rotatably retained in a ball holding unit (3). An ink communication space (5), which communicates with this ball holding unit (3), is defined between the outer surface portion (6) of the ball retaining core (2) and the inner surface portion (7) of the ball holding tube (1) in such a manner that ink can flow in an axial direction through capillaries. A projecting wall portion (12) is formed between the external portion (9) of a substantially flat, ball retaining portion (8) of the ball retaining core (2) at the ball holding unit (3), the surface portion (10) of the ball (4) adjacent to the former and the inner surface portion (11) of the ball holding tube (1), so that a capillary guide path (13) of the ink communicating with the ink communication space (5) is defined between the surface portion (10) of the ball (4) and the projecting wall portion (12). The projecting wall portion (12) of this pen tip structure is formed at the external portion (9) and/orthe inner surface portion (11). The cross-sectional area of the ink communication space (5) is set to be greater than that of the capillary guide path (13) without changing the capillary gap.

摘要： A pen nib (1), preferably for use in a high speed writing, has a coaxial capillary passage (3) for ink which extends axially in the nib body, and has, in a cross-sectional view, a coaxial portion (3c), a plurality of outer portions (3a) and intermediate connecting portions (3b) between the coaxial portion and respective outer portions. The coaxial passage (3) partially opens axially at peripheral openings (2A) formed in a round or pointed head of the nib i.e. the coaxial portion (3c) and intermediate portions (3b) are all closed axially at the head, while the outer portions (3a) are open axially at the peripheral openings (2A), which are arranged at a top surface of the head around the center thereof. The intermediate passage portions (3b) may be open radially at the peripheral openings (2A).
The nib is made of hard, wear resistant material, such as metal, ceramic or thermosetting resin by injection molding with a subsequent heat treatment. Each peripheral opening (2A) is preferably chamfered (at 4) to give a round edge, and maybe formed to have a groove following the round edge for guiding and discharging dust from the utmost radially outer edge thereof.摘要翻译： 优选用于高速书写的笔尖（1）具有用于在笔尖体中轴向延伸的油墨的同轴毛细通道（3），并且在横截面图中具有同轴部分（3c） ，多个外部部分（3a）和中间连接部分（3b）之间，在同轴部分和相应的外部部分之间。 同轴通道（3）在形成在笔尖的圆形或尖头的周边开口（2A）中部分地开口，即同轴部分（3c）和中间部分（3b）都在头部轴向封闭，而外部部分 （3a）在周边开口（2A）处轴向敞开，周围开口（2A）布置在围绕其中心的头部的顶表面处。 中间通道部分（3b）可以在周边开口（2A）处径向开口。 笔尖由硬质耐磨材料制成，如金属，陶瓷或热固性树脂，经后续热处理注射成型。 每个周边开口（2A）优选地被倒角（在4处）以形成圆形边缘，并且可以形成为具有沿着圆形边缘的凹槽，用于从其最大的径向外边缘引导和排出灰尘。

摘要： Disclosed is a probe for dental therapy and examination, which comprises an elongate bundle (1) of fibers extending generally parallel to the axis of elongation. The bundle is narrowed at one or both of its ends (2, 2'. 2"), and the fibers are secured to each other so that the fiber bundle (1) is coherent but the fibers define capillary passageways (5) therebetween. The narrowed ends(s) (2) may have a globular enlargement (3) or may be sharp ended (2') or blunt-ended (2"). One end of the bundle may be enlarged to form a handle portion (6).
