摘要:
A printing apparatus having a printing head that prevents ink, diluent, and a mixed solution thereof from adhering to and spreading about a portion of the printing head around a nozzle. The printing apparatus has an enhanced ability to reproduce a gradation of concentration, thereby making it possible to form a recorded image of high resolution. The printing head has a first nozzle, which discharges a discharge medium, and a second nozzle, which discharges a metering medium. The orifices of the first and second nozzles are adjacent to each other in a nozzle outlet face of the printing head. A groove, a hydrophilic portion, or an insular projection is formed between the first and second nozzles to control the spread of ink, diluent, and a mixed solution thereof around the nozzles. The hydrophilic portion may be made by a non-processed portion of the outlet face of the printing head, and a portion other than the nonprocessed portion may be made a hydrophobic portion. Several variations of the groove, hydrophilic portion, and insular projection are disclosed.

A printer comprising a printing head for discharging ink alone or ink and diluent according to the present invention employs a polyimide polymer at least around nozzle opening(s) on the nozzle opening side of the printing head so as to enable to form a recorded image of a high resolution as well as to enhance the productivity. It is preferable that the polyimide polymer have a coefficient of water absorption as 0.4 (%) or below when dipped in water of 23 (°C.) for 24 hours. Furthermore, it is preferable that the printing head excluding the portion made from the polyimide polymer be made from polysulfone, polyethersulfone, or a polyimide polymer having a coefficient of water absorption as 1.0 (%) or above when dipped in water of 23 (°C.) for 24 hours. Moreover, it is preferable that nozzles are formed by ablation processing using eximer laser.

A plate material 1 and piezoelectric ceramics 2 are bonded together through an alloy layer 3 formed by an alloy forming reaction due to the mutual diffusion phenomena between a liquid metal including at least galium and the plate material 1 or the piezoelectric ceramics 2, or the mutual diffusion phenomena between the liquid metal and metal powder. The alloy layer 3 may include at least one or more of indium, tin and zinc and at least one or more of copper, silver, gold, and palladium. Further, a metal may be provided on at least one of the bonded surfaces of the plate material 1 and the piezoelectric ceramics 2. This metal may include one or more of copper, silver, gold, tin and palladum. In addition, a metal layer may be formed on the bonded surface 1a side of the plate material 1. Still further, an amorphous layer may be formed on at least one of the parts between the plate material 1 and the alloy layer 3, and between the piezoelectric ceramics 2 and the alloy layer 3.

In a printer according to the present invention, a diaphragm provided with a thermoplastic layer and a pattern layer is set on the main surface of a pressure chamber forming part in which a liquid supply passage is formed, when the thermoplastic layer of the diaphragm is pressed, heated and bonded onto the pressure chamber forming part, pressure is applied only to the pattern layer of the diaphragm, no unnecessary pressure is applied to a part opposite to the liquid supply passage in which the pattern layer is not formed, the liquid supply passage is prevented from being blocked by the thermoplastic layer, and operation for bonding the diaphragm to the pressure chamber forming part in which the pressure chamber is formed is facilitated.Further, in the printer according to the present invention, an adhesive layer consisting of thermoplastic resin is formed between the pressure chamber forming part and the diaphragm and the bonding strength of the diaphragm to the pressure chamber forming part is sufficiently secured. Also, in the printer, each nozzle is formed in a nozzle forming member, if an adhesive layer consisting of thermosetting resin is formed between the pressure chamber forming part and the nozzle forming member, the pressure chamber forming part and the nozzle forming member are bonded under room temperature after the diaphragm and the pressure chamber forming part are bonded, at this time the adhesive layer consisting of thermoplastic resin is not influenced, no heat is also applied to a liquid repelling film if the liquid repelling film is formed on the nozzle forming member, and a range in which the liquid repelling film is selected is widened.
摘要:
A method of controlling the domain of a nonlinear ferroelectric optics substrate to form an inverted-domain structure in one major surface of a single-domain nonlinear ferroelectric optics substrate. A first electrode is formed in a first major surface of a nonlinear ferroelectric optics substrate in a pattern corresponding to a desired pattern of an inverted-domain structure to be formed, a second electrode is formed on a second major surface opposite the first major surface in a pattern corresponding to that of the first electrode or in a solid film, a dc voltage or a pulse voltage is applied across the first and second electrodes to form local, inverted domains in the desired pattern in the first major surface of the nonlinear ferroelectric optics substrate. An insulating film may be formed between the first electrode and the first major surface to avoid damaging crystals of the nonlinear ferroelectric optics substrate by the current that flow across the nonlinear ferroelectric optics substrate when the dc voltage or the pulse voltage is applied across the first and second electrodes.

An image acquisition apparatus includes an optical system, an imaging device, a movement controller, and a multiple exposure processing unit. The optical system includes an objective lens for magnifying a portion of an imaging target. The imaging device is capable of performing all-pixel simultaneous exposure and is configured to image the portion magnified by the optical system. The movement controller is configured to move a focal point of the objective lens in a thickness direction of the portion of the imaging target. The multiple exposure processing unit is configured to perform multiple exposure of the imaging device at a plurality of positions such that, for each of ranges sectioned by positions in a direction in which the focal point is movable, an average image that covers each of the ranges is obtained.

A connector provided on a projector has an RF chip. A plug connected to the connector has an RF chip at a position opposite to the RF chip of the connector. When a protruding section of the plug is inserted and fit into an aperture section of the connector, the RF chip of the plug and the RF chip of the connector perform wireless communication with each other in a non-contact state. Thus, a connecting tool can be easily attached to/detached from a receiving tool without breaking a terminal due to contact such as in a case where a conventional contact type terminal is used.
