Abstract:
A carrier and a substrate are aligned even if an imager cannot be simultaneously focused on alignment marks formed on both the carrier and the substrate. Center of gravity positions G1m of an alignment pattern element AP1 on a substrate and G2m of an alignment pattern element AP2 on a transparent blanket are calculated by image processing from an image IM imaged via the blanket by a CCD camera. The position of the center of gravity Gm2 is specified by a process associated with edge extraction from the image imaged with the alignment pattern element AP2 on the blanket being in focus. High spatial frequency components are removed and low frequency components are extracted for the alignment pattern element AP1 on the substrate imaged out of focus to have a blurred outline, and the position of the center of gravity G1m is specified from an extraction result.

Abstract:
A print section patterns a coating layer to form a pattern layer on a carrier and then transfers the pattern layer to a substrate. A controller obtains a first carrier thickness by measuring the thickness of the carrier carrying the coating layer and adjusts a gap between the carrier carrying the coating layer and the printing plate based on the first carrier thickness immediately before the coating layer is patterned. The controller also obtains a second carrier thickness by measuring the thickness of the carrier carrying the pattern layer and adjusts a gap between the carrier carrying the pattern layer and the substrate based on the second carrier thickness immediately before the pattern layer is transferred.
Abstract:
The supply of a negative pressure to an opening P(+1) adjacent to an opening P(0) is stopped by switching a suction valve connected to the opening P(+1) from an open state to a closed state while keeping a positive pressure valve connected thereto closed. Then, near the opening P(+1), a force for holding a blanket becomes gradually weaker against a pressure force in a pressurized space. Associated with that, an air component in the pressurized space flows into a space between a portion of the blanket vertically above the opening P(+1) and an upper surface, whereby the blanket portion is lifted from the upper surface and brought into contact with the lower surface of a printing plate. In this way, a contact area is slowly and stably widened while a sudden change of a pressure in the pressurized space SP5 is suppressed.
Abstract:
In a thermal type flowmeter 60, a heating/heat-sensitive coil 64 which is shaped as a coil is fit close into an approximately central portion of a duct pipe 63. A flow rate computing circuit 65 supplies electric power to the heating/heat-sensitive coil 64 in accordance with an instruction received from a control portion, the heating/heat-sensitive coil 64 develops heat, and the heat developing at the heating/heat-sensitive coil 64 heats up a hole transporting material 8 which flows through the duct pipe 63. Further, the flow rate computing circuit 65 which is electrically connected with the heating/heat-sensitive coil 64 detects a difference between an upstream-side temperature and a downstream-side temperature, and calculates the flow rate (mass flow rate) of the hole transporting material 8 based on this temperature difference, the amount of heating, physical properties data such as the specific heat and the heat capacity regarding the hole transporting material 8.
Abstract:
A non-oil repellent photosensitive material layer 2 and an oil repellent photosensitive material layer 3 formed by coating on a substrate 1 are exposed at the same time with light having a single wavelength (I-line) in accordance with bank regions and thereafter developed. In consequence, banks 300 are formed having a double-layer structure which is comprised of bottom layer portions 31 of a non-oil repellent material and top layer portions 32 of an oil repellent material. This blocks organic EL materials supplied between the banks 300 from moving beyond tops of the banks 300 and prevents color mixing of the organic EL materials. Further, since the bottom layer portions 31 between which organic layers are formed are made of the non-oil repellent material, the profiles of the organic layers will not change due to surface tension.
Abstract:
Using a mixture of (BAYTRON P) of PEDT (polyethylene dioxythiophene) and PSS (polystyrene sulfonic acid) as a hole transportation material and using water and ethanol as polar solvents, a coating composition having a contact angle of 35 degrees or smaller with respect to an ITO layer is obtained. The coating composition is then poured for coating upon exposed surfaces of first electrodes (ITO) 4R, 4G and 4B enclosed by barrier walls 6. Thus applied coating composition uniformly spreads all over the first electrodes 4R, 4G and 4B. As the coating composition naturally dries at a room temperature for about fifteen seconds, the solvents are removed from the coating composition.
