Abstract: An ink tank is detachably held by a tank holder having an arc shape portion of a specific curvature. This ink tank has also an arc shape portion of a specific curvature, and the arc center of the arc shape portion of the ink tank is in the same position as the arc center of the arc shape portion of the tank holder only when the ink tank is correctly installed on the tank holder. The ink tank is provided with the movable lever having the engagement nail to engage with the tank holder, and the movable lever is provided with the tongue portion on the upper portion of the engagement nail to be operated when the ink tank is removed from the tank holder, and the arc shape portion of the ink tank is the portion of the arc shape formed for the tongue portion. With the structure thus arranged, it becomes possible to facilitate the user to install the ink tank on the tank holder correctly and reliably without exercising any extra force leading to the damage that may be caused to the ink tank.

Abstract: A solid type semiconductor device comprises energy converting means for converting energy from outside, and operating means operated by energy converted by the energy converting means. The energy converting means converts the electromotive force supplied from the outside to the device in non-contact into electric power. The operating means comprises information acquiring means actuated by electric power obtained by energy converting means; discriminating means; information accumulating means; and information communicating means.

Abstract: A forming method for a fiber aggregate in which fibers are heated to be welded with each other, the method includes a heating step of applying upward heated air to a bottom of a block of the fibers to pass the heated air therethrough and to cause the block of fibers to float, wherein at least parts of fibers are melted while the block of the fibers float; a compression step of compressing substantially in a vertical direction the heated block of fibers into a desired height; and a cooling step of cooling the compressed block of fibers to solidify melted portions of the fibers at portions where the fibers intersect with each other.

Abstract: An ink tank provided with an ink containing portion containing ink therein, and a housing protecting the ink containing portion is characterized by a resin material capable of transmitting therethrough visible light and infrared light travelling from the exterior of the housing toward the interior of the ink containing portion and capable of decreasing ultraviolet light travelling from the exterior of the housing toward the interior of the ink containing portion.

Abstract: A method for inserting an absorbent to a container of which receiving space is smaller than the absorbent, and a container receiving an absorbent inserted by the method. The method includes the steps of compressing the absorbent with a first and a second pressing members, inserting the absorbent to the container, together with the first and the second pressing members, and removing the first and the second pressing members from the container while the absorbent is held in the container, wherein the electric charge on the first and the second pressing members contacting with the absorbent is removed.

Abstract: To provide a recording liquid feed path, recording liquid container, and recording liquid feed device having the same, as well surface modifying method for the recording liquid feed device to feed efficiently a recording liquid for ejection through a feed tube. If the interior of the feed tube is not rendered hydrophilic as shown in FIG. 3A, air which has passed through a wall of the feed tube forms a bubble, which bubble adheres to an inner surface of the feed tube and obstructs a flow of the recording liquid. But if the inner surface of the feed tube is rendered hydrophilic to form a hydrophilic surface as shown in FIG. 3B, the recording liquid is conducted along the hydrophilic surface at the inner surface portion of the feed tube with the bubble adhered thereto, so that the adhesion area of the bubble to the feed tube inner surface is reduced and the bubble floats from the inner surface.

Abstract: An ink tank having a negative pressure generating member for retaining ink, a case for accommodating the negative pressure generating member, the case having an atmosphere communicating portion held in communication with the atmosphere and an ink supply portion through which the ink is led out to the exterior, and an ink holding member disposed near the ink supply portion and developing a higher capillary action than the negative pressure generating member, wherein a recess is formed in an inner surface of a side wall of the case adjacent to a wall provided with the ink supply portion, the recess extending in a direction from the side of a wall opposing the wall provided with the ink supply portion toward the ink supply portion. Alternatively, in an ink tank having no ink holding member, at least a part of inner surfaces of the case is subjected to pear-skin treatment. With those ink tanks, a satisfactory ink supply ability is obtained while achieving a reduction of the tank size.

Abstract: A method for inserting an absorbent into a container wherein a receiving space for the absorbent is smaller than the absorbent, and a container receiving an absorbent inserted by the method. The method includes the steps of compressing the absorbent with first and second pressing members, inserting the absorbent into the container together with the first and second pressing members, and removing the first and second pressing members from the container while the absorbent is held in the container, wherein an electric charge on the first and second pressing members contacting the absorbent is removed.

Abstract: A fiber body which exhibits sufficient ink supplying characteristics for keeping up with the trend toward diversification of ink and high printing speed while ensuring an easy and simple ink injection operation and a liquid container having the same. The ink tank has a PP fiber body (crosshatched area of the figures), as a negative pressure generating member for an ink jet head which ejects liquid to perform recording, arranged almost all over the interior thereof, so as to allow the fiber body to hold a liquid to be supplied to an ink jet head. On the top of the tank casing, provided is an atmosphere communication port. And as a PP fiber body, used is an assembly of intertwined PP fibers of which surface has been subjected to surface treatment of giving hydrophilic nature thereto.
