Abstract: PROBLEM TO BE SOLVED: To eject an ink drop well by providing a step at the part of an ink ejection hole composed of a layer at an ink repellent or ink nonaffinitive part such that the ejection side of the layer is made narrower. SOLUTION: An ink repellent ejection hole 1 and an ink affinitive ejection hole 2 are provided. In order to set a constriction of ink, a step 3 projecting inward by a distance H is arranged at the forward end of the ink repellent ejection hole. Radiuses R' and R of the ink affinitive ejection hole 2 and the ink repellent ejection hole 1 satisfy a relation R>=R' Distance of the ink repellent ejection hole is L and a relation L

Abstract: PROBLEM TO BE SOLVED: To make a means for changing moving directions simple, small-sized and electrically controllable for a machine whose structure is very much miniaturized such as a micromachine. SOLUTION: An ink jet 1H on the tip side of a moving body 2 discharges and nebulizes liquid 6 that reduces friction resistance. The moving body 2 moves on to a move-face 3 sprayed with liquid 6 by inertial force of the movement so that the friction resistance alteration liquid 6 is placed between the moving body 2 and the move-face 3. Thus, the friction resistance between the moving body 2 and the move-face 3 alters partly and the moving body 2 produces rotative force. This rotative force turns moving direction of the moving body 2.

Abstract: PROBLEM TO BE SOLVED: To provide the packaging shape for an ink cartridge suitable for the environment not using an aluminum composite film in which the evaporation amount of water content in ink is small and ammonia generated from an ink component and filled in the package can be reduced to a large extent. SOLUTION: An ink cartridge packaging shape is provided with a metal container 1 formed of a steel plate with its surface coated with rust-proof varnish, an easy-peeling film cover 2 composed of a copolymer of polyethylene containing 10% vinyl acetate or more and vinyl acetate and having a bonded layer of 50 μm thickness or more and a silica deposit film and a biodegradable cushioning material 3 disposed in the container.

Abstract: PROBLEM TO BE SOLVED: To block steam surely by making a package container for containing an ink jet head of a resin material deposited with a composite material of SiO2 and Al2 O3 and composing the adhesive layer of a film for closing the container of a specified propylene resin layer. SOLUTION: An ink cartridge 1 is held in the recess of a blister container 2 and a cover material 6 of a silica deposited film 3 is applied to the recess and heat sealed 17 to constitute a package container. The package container is composed of SiO2 or Al2 O3 or a resin material deposited with a composite material of SiO2 and Al2 O3 . The silica deposited film 3 is formed laminating a film 14 and an adhesive layer 15 onto a polyester base film 13 deposited with silicon oxide 12. The adhesive layer 15 is composed of polypropylene having molecular weight not larger than 80,000 in order to prevent permeation or evaporation of steam.

Abstract: PROBLEM TO BE SOLVED: To protect an ink discharge face from vibration and shock when an ink jet head cartridge is distributed, and prevent ink from flowing out due to the peeling of a protective tape by protecting the ink discharge face of a recording head part with the protective tape and disposing a flexible body in a packing box so as to pressurize the protective tape when the cartridge is packed. SOLUTION: A flexible body 8 is first bonded and fixed to a packing box 9 by a hot melt 10. This flexible body 8 made of a sponge is so disposed as to pressurize a protective tape 3 under the pressure of 0.5-12g/mm . An ink jet head cartridge 7 is contained in the packing box 9 in such a way that the protective tape 3 is brought into contact with the flexible body 8, and, when the packing body 9 is closed, a portion of the cartridge 7, which is protected by the protective tape 3, is pushed into the flexible body 8 to be pressurized. A corrugated board, etc., are used as the packing box 9 according to the weight, etc., of the cartridge to be contained. By forming the packing box in such a manner, a protective function for an ink discharge face is sufficiently exhibited, and, moreover, a protective function for the whole cartridge can also be exhibited.

Abstract: PROBLEM TO BE SOLVED: To certainly perform the opening of the tip of an atmosphere communication port essential from a functional aspect at a time of the leakage of ink during delivery and at a time of the opening of an ink tank regardless of the form of the ink tank. SOLUTION: The packing structure of an ink tank 4 equipped with an ink supply port 9 and an atmosphere communication port 7A contains the ink supply port hermetically closing member 2 hermetically closing the ink supply port 9, the atmosphere communication port hermetically closing members 1, 1' hermetically closing the atmosphere communication port 7A and the monolithic cover member 3 containing both hermetically closing members and covering the ink tank 4. The atmosphere communication port 7A is opened first by the partial breakage of the covering member 3 accompanied by the removal of the atmosphere port hermetically closing members 1, 1'.
