In a layout pattern generating method, a specific rework cell used for edition is specified among rework cells and fill cells which are arranged in a semiconductor chip area and a specific pattern of a predetermined shape is generated in a wiring layer for the specific rework cell. A dummy wiring pattern is arranged in at least a part of the wiring layer of and the fill cell and un-specific rework cells among the rework cell other than the specific rework cell. The specific pattern is deleted from the wiring layer for the specifying rework cell. A wiring pattern is arranged in the wiring layer for the specific rework cell by wiring the specific rework cell as a logic cell.

A trimmer blade comprises a fixed blade unit and a movable blade unit. Then, said fixed blade unit comprises a comb-shaped blade section having a plurality of blades and a plurality of gullets, and said plurality of blades are arranged alternately with said plurality of gullets. Then, said movable blade unit comprises a comb-shaped blade section having a plurality of blades and a plurality of gullets, and said plurality of blades are arranged alternately with said plurality of gullets, and said movable blade unit is configured to slide on said fixed blade unit while reciprocating. A width of each gullet of said movable blade unit is set so that at least two gullets of said fixed blade unit fall inside each gullet of said movable blade unit, as viewed from a direction perpendicular to a sliding surface between said movable blade unit and said fixed blade unit.
摘要:
A liquid ejection head including an ejection orifice for ejecting a liquid; a flow path for supplying the liquid from a liquid supply port holding the liquid to the ejection orifice; and a heat generating element of a rectangular form with a long-side to short-side ratio of 2.5 or more for generating thermal energy used to eject the liquid, a longitudinal direction of the heat generating element being arranged along an extending direction of the flow path. An end portion of the heat generating element on a downstream side of a liquid flowing direction within the flow path is located between an end portion of the ejection orifice on the downstream side and an end portion of the ejection orifice on an upstream side when viewed from a direction to which the liquid is ejected from the ejection orifice.

A liquid ejection head includes ejection orifices allowing liquid to be ejected therethrough, passages communicating with the ejection orifices and the pressure chambers each accommodating an energy generating element generating energy for ejecting the liquid therein, a supply port supplying the liquid to the passages, and a filter including substantially cylindrical members between the supply port and passages and having openings. Each of the ejection orifices has a substantially circular cross section having larger and smaller diameters substantially perpendicularly to its liquid ejecting direction. Each of the openings has a substantially rectangular cross section having longer and shorter sides substantially perpendicularly to its liquid supplying direction. The relationships D1>L1, D1 L2≧D1 are satisfied where D1 is the smaller diameter, D2 is the larger diameter, L1 is the shorter side, and L2 is the longer side.
摘要:
A liquid ejection recording head includes an element substrate having plural ejection energy generating elements, an ejection outlet array of plural ejection outlets, and bubble generation chambers. The element substrate includes a first liquid supply port provided along an arrangement direction of the ejection outlets, and plural second ink supply ports disposed between a lateral end of the substrate and the chambers. Each bubble generation chamber communicates with the first and second liquid supply ports through first and second liquid supply passages, respectively. The element substrate has a thermal resistance against heat flowing from the ejection energy generating elements along a direction perpendicular to the array direction and parallel to a surface of the substrate. The thermal resistance, per unit length with respect to the array direction, at both end portions of the array is larger than that at a central portion of the ejection outlet array.

A liquid-discharge recording head includes large nozzles for discharging large liquid drops and medium and small nozzles for discharging medium and small liquid drops that are smaller than the large liquid drops. The large nozzles are arranged on one side of an ink-supply opening and the medium and small nozzles are arranged on the other side of the ink-supply opening. The number of large nozzles is greater than the number of medium and small nozzles, and the liquid-discharge recording head performs high-speed printing using the large nozzles, high-speed photo printing using the medium and small nozzles, and high-quality photo printing using the small nozzles.
