摘要： An ink jet head comprises a plurality of discharge pressure generating elements serving as the discharge pressure source for discharging an ink droplet, an orifice plate having a plurality of ink discharge ports corresponding to the respective discharge pressure generating elements formed therefor, an ink supply port for supplying ink and a nozzle wall forming an ink flow path communicating the ink discharge ports with the ink supply port. The orifice plate and the nozzle wall are formed by resin material, and also, a thin metallic film is formed on the outer surface of the orifice plate. If desired, a water-repellent film is formed further on the surface of the thin metallic film. With the metallic film formed on the surface of the orifice plate, the moisture in ink is effectively prevented from being evaporated. Further, with the provision of the metallic film, it becomes possible to perform the eutectoid plating for the formation of the water-repellent film. With the head thus structured, it becomes possible to stably obtain excellent print quality.

摘要： In a printing apparatus using a plurality of heating elements as printing elements, there are provided CCD elements for storing electric charges whose quantity correspond to temperatures in correspondence to each of the printing elements, and for sequentially transferring these electric charges. As a printing head driving apparatus, an analog shift register having a series of CCD elements is employed in order to perform data transfer operation, data alignment, and driving operations of the respective printing elements. Also, the above-described CCD elements are commonly used with CCD elements for storing and transferring temperature data. As a result, a compact printing apparatus can be made while suppressing shading in images caused by temperature increasing due to the driving operation of the printing elements.

摘要： A liquid jet recording head includes a plurality of ejection outlets through which droplets of liquid are ejected by thermal energy, a plurality of liquid passages communicating with the ejection outlets to supply the liquid, a plurality of supply inlets for supplying the liquid to the passages and a plurality of electro-thermal transducers provided for the respective ejection outlets to produce the thermal energy. Each of the electro-thermal transducers has a heating surface, on the bottom of a corresponding passage, for heating the liquid, and the width of each passage measured in the direction in which the passages are arranged is a maximum at a position between an end of the electro-thermal transducer element near the ejection outlet and an end thereof near the supply inlet, and the width decreases both toward the ejection outlet and toward the supply inlet. This allows the bubble created in the passage by the transducer to expand freely and provides energy-efficient droplet ejection.

摘要： In the invention, a plane region to which characters are output is divided into lattice-like elements (orthogonal lattice, triangular lattice, hexagonal lattice, etc.). In each element, an area ratio of the area to be output to the element is previously stored. The portion in the element in which the area ratio is equal to a first predetermined value (area ratio=0) is not output. The portion in the element in which the area ratio is equal to a second predetermined value (area ratio=1) larger than the first predetermined value is output. Further, the portion in the element in which the area ratio is larger than the first predetermined value and is smaller than the second predetermined value is regarded as a distribution of the continuous area ratio on the basis of the values of the area ratios of such an element and the elements therearound. The portion in which the area ratio is equal to or larger than a third predetermined value is output.
