A method for producing an ink jet head including, on a substrate, a piezoelectric element for discharging an ink from a discharge port, and an ink flow path communicating with the discharge port so as to correspond to the piezoelectric element, the method comprising in this order a step of providing, on the substrate, a mold material corresponding to the ink flow path, a step of providing a wall material of the ink flow path so as to cover the mold material, a step of eliminating a portion of the substrate corresponding to the piezoelectric element thereby forming a space in the substrate, and a step of eliminating the mold material thereby forming the ink flow path.
摘要:
A process for producing a light amount-adjusting member, such as an ND filter, that comprises the steps of providing a transparent base material and a coloring liquid; and applying a coloring liquid to the base material by ejecting the coloring liquid to the base material to form a colored portion having a specified optical density, wherein the coloring liquid contains at least one coloring material of with a maximum absorption wavelength in a range of 630 to 750 nm, when measured on the transparent base material.

A liquid ejection apparatus comprises a liquid bag for containing liquid to be supplied to a liquid ejection head and is adapted to generate negative pressure in the liquid ejection head by a water head difference between the liquid ejection head and the liquid bag. The liquid bag is arranged so that, of two sides of the liquid bag having the largest areas, the side facing in a direction opposite to the direction of gravity is rigidly held at least partly and the other side is freely movable. The liquid bag is provided with a means for detecting an amount of liquid remaining in the liquid bag by reference to a position of the side facing in the direction of gravity, and the detecting means is adapted to move according to the amount of liquid contained in the liquid bag.

A sheet conveying device includes an endless conveyor belt which has an electrode unit for retaining the sheet by using an electric force and which rotates while retaining the sheet so as to convey the sheet, a first electricity-supplying unit which applies a voltage to the electrode unit while it passes through a predetermined area, a second electricity-supplying unit which is disposed at a predetermined position which is upstream of the predetermined area and downstream of a position where the conveyor belt receives the sheet along a sheet-conveying path, and which applies another voltage to the electrode unit while it passes by the predetermined position, a detecting unit which detects a current or a voltage when the second electricity-supplying unit supplies electricity, and a determining unit which determines the state of the surface of the conveyor belt on the basis of the detected current or voltage.
摘要:
An ink-jet recording apparatus and recording method uses a recording head wherein nozzles with small diameter are arrayed in high density, to achieve both high quality and high speed. Accordingly, whether to record a certain area in the image with recording ink alone or with both recording ink and clear ink is determined according to the image data of the certain area, and recording is performed based on the determined results, using a recording head wherein ink discharging nozzles and clear ink nozzles are arrayed alternately.
摘要:
An apparatus and method for producing an optical recording medium or an optical recording medium substrate sheet forms an photo-curable resin layer on at least one of a substrate sheet and a stamper which undergoes elastic deformation. The stamper bears a pattern corresponding with preformatting information and is brought into close contact with the substrate sheet wherein the photo-curable resin layer is interposed between them and cured.
摘要:
A roll stamper which molds a substrate resin sheet into an information recording media by continuously transferring preformat patterns on the substrate resin sheet, and a production process therefor. The preformat pattern on the roll stamper has a value of b/a of greater than 1 when the length of the preformat pattern in a direction parallel to the direction in which the resin sheet is transported is defined as a and the length in a direction perpendicular thereto as b.
摘要:
A method for forming a substrate sheet for optical recording media having a preformat on the surface is disclosed. This method has the steps of extruding a melted resin to form a melted resin sheet, pressing the melted resin sheet between a mirror roll and a resin roll prior to the curing of the melted resin sheet, thereby forming a resin sheet, the resin roll being disposed in the face of the mirror roll and being covered on the peripheral surface thereof with a resin, and forming a photocurable resin composition layer on the surface of the resin sheet with which the resin roll has come in contact, and forming the preformat on the photocurable resin composition layer.
摘要:
A process for producing a roll stamper which molds a substrate sheet for information recording mediums by continuously transferring preformat patterns on a resin sheet. The roll stamper has the feature that the preformat pattern on the roll stamper has a value b/a of greater than 1, where the length of the preformat pattern in the direction parallel to the direction in which the resin sheet is transported is defined as a and the length in the direction perpendicular thereto as b.
