摘要:
A magnetic recording medium in accordance with the present invention is constituted by a first magnetic film having a magnetic anisotropy in a first direction parallel to the film surface and a second magnetic film that is formed on the first magnetic film and that is made of an amorphous alloy film of a rare-earth metal and a transition metal having a magnetic anisotropy in a second direction that is parallel to the film surface, and different from the first direction. In the above-mentioned magnetic recording medium, the first and second magnetic films have magnetic anisotropies having directions parallel to their surfaces and different from each other. When a magnetic latent image is formed on the magnetic recording medium of this type, it is possible to reduce the height of serration in the serrate magnetization transition structure appearing in the border of magnetization inversion in the magnetic latent image. Consequently, it becomes possible to improve the resolution of the magnetic-latent-image recording, and also to provide magnetic latent images with high resolution and high magnetic attracting force to magnetic toner.

A thermomagnetic printer of the in-plane magnetization system includes a magnetic recording layer made of Dy.sub.x Co.sub.(1-x) or Dy.sub.y Co.sub.(1-y) and a base layer made of Ti or Ta. Since the described arrangement enables the magnetic recording layer to be formed by the sputtering method or the electron beam evaporation method, and the like, the magnetic recording layer having a uniform thickness and properties in a large area can be formed without difficulties. In addition, by adopting the Ti layer or the Ta layer as the base layer, a reduction in a residual magnetization can be prevented even when the magnetic recording layer is made thicker, thereby increasing a magnetic attraction force.

In a droplet spray apparatus spraying out ink from an ink path by altering the volume of an ink channel formed in a trench that is covered with a cover plate and that has a conductive member provided at one end formed at a piezoelectric member, an ink supply opening to supply ink is provided at the end side where the conductive member is provided. Accordingly, an ink jet head that can be made compact, fabricated easily, and superior in productivity is obtained.

An object is to provide a printing apparatus or the like that improves printing accuracy when a carriage moves back and forth for printing. A block 51 on a block surface plate is mounted on the block surface plate at a predetermined location. On the other hand, a substrate 54 on a print surface plate is mounted at a location corresponding to the location of the block 51, that is, a location where a picture transfer is desirably received from a blanket cylinder 13. In the present invention, the arrangement of sliders 52 and 40 for the block carriage 50 and a printing carriage 7 to reciprocate along two rails 30 in the block carriage 50 and that in the printing carriage 7 are the same. With such an arrangement, at the same location immediately below the blanket cylinder 13 on the same track 30, even when the straightness of the rail 30 is not sufficient, the block 51 and the glass substrate 54 take the same position at the location, and thus print misalignment can be prevented.

An ink jet head includes a base with front and rear ends having a plurality of channel grooves separated by channel walls each including a piezoelectric extending to the rear end, a cover that is placed on the base to be in contact therewith and opposite to the face of the base that has the channel grooves, electrodes placed on at least part of the inner surface of each one of the channel grooves, a conductive resin electrically connected with the electrode plugging up each of the channel grooves at the rear end, and projections as a pressing means for pressing the top of the conductive resin at the rear end of each channel groove.
摘要:
In a vessel (2) to which waste liquid (11) which contains ink pigment, water and cleaning liquid used in a printer is supplied, a metal electrode plate (30a, 30b) which allows the waste liquid (11) to flow therethrough is disposed to partition the inside of the vessel (2) into a first region (a) and a second region (b). A high voltage from a high-voltage power supply (7) is applied to the metal electrode plate (30a, 30b) while a grounding electrode (20) is connected to the first chamber (a) to generate an electrostatic field between the metal electrode plate (30a, 30b) and the grounding electrode (20) so that the water and the ink pigment are electrostatically agglomerated from the waste liquid (11) making use of electrophoresis of the ink pigment by the electrostatic field thereby to separate the waste liquid in the first region (a) into the cleaning liquid, water and ink pigment.
摘要:
A recording head for a magnetic printer utilizes a so-called magnetography, in which a magnetic latent image formed on a magnetic recording medium is developed and actualized by a magnetic toner and which image is transferred and fixed on a sheet of recording paper to provide a hard copy. The recording head for a magnetic printer includes a first thermal head member, second thermal head member juxtaposed with the first thermal head member with a space therebetween, and a magnetic head member arranged on the first and the second thermal head members. A magnetic gap of the magnetic head member extends immediately above the space between the first and the second thermal head members linearly in the same direction. By this structure, a recording head for a magnetic printer which has simple structure and allows formation of a magnetic latent image having clear boundary between opposite magnetic polarities on a magnetic recording medium, is provided.

A method of manufacturing a stamper includes the steps of coating a flat surface of a substrate with photosensitive material; directing light to a specified position on the photosensitive material to expose it; developing the photosensitive material to make a minute photoresist pattern; etching the substrate to a specified depth with a mask of the photoresist pattern; removing the photoresist as the mask to make a glass master; arbitrarily forming a first nickel layer on a surface of the glass master; forming an intermediate layer of a metal having a smaller linear expansion coefficient than nickel over the first nickel layer; forming a second nickel layer on the intermediate layer to form a conductive film having a two- or three-stratum structure; arbitrarily subjecting the whole substrate to a process to make nickel passive; forming an electroformed layer on the conductive film by an electroforming process; and separating the conductive film from the glass master.
