Force for biasing a roller member is changed according to the contact state of first and second plate-like bodies during the travel of the roller member. By that, the pressing force per unit area given from the second plate-like body to the first plate-like body during travel is suppressed. An object to be transferred is satisfactorily transferred despite a change in the contact state of the plate-like bodies during the travel of the roller member.

Transfer apparatus and transfer method

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 Gof an alignment pattern element APon a substrate and Gof an alignment pattern element APon 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 Gmis specified by a process associated with edge extraction from the image imaged with the alignment pattern element APon the blanket being in focus. High spatial frequency components are removed and low frequency components are extracted for the alignment pattern element APon the substrate imaged out of focus to have a blurred outline, and the position of the center of gravity Gis specified from an extraction result.

Alignment method, transfer method and transfer apparatus

The supply of a negative pressure to an opening P(+) adjacent to an opening P() is stopped by switching a suction valve connected to the opening P(+) from an open state to a closed state while keeping a positive pressure valve connected thereto closed. Then, near the opening P(+), 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(+) 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 SPis suppressed.

Pattern forming apparatus and pattern forming method

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.

A non-oil repellent photosensitive material layerand an oil repellent photosensitive material layerformed by coating on a substrateare exposed at the same time with light having a single wavelength (I-line) in accordance with bank regions and thereafter developed. In consequence, banksare formed having a double-layer structure which is comprised of bottom layer portionsof a non-oil repellent material and top layer portionsof an oil repellent material. This blocks organic EL materials supplied between the banksfrom moving beyond tops of the banksand prevents color mixing of the organic EL materials. Further, since the bottom layer portionsbetween 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.

Substrate for organic EL and method for manufacturing the same

In a thermal type flowmeter, a heating/heat-sensitive coilwhich is shaped as a coil is fit close into an approximately central portion of a duct pipe. A flow rate computing circuitsupplies electric power to the heating/heat-sensitive coilin accordance with an instruction received from a control portion, the heating/heat-sensitive coildevelops heat, and the heat developing at the heating/heat-sensitive coilheats up a hole transporting materialwhich flows through the duct pipe. Further, the flow rate computing circuitwhich is electrically connected with the heating/heat-sensitive coildetects a difference between an upstream-side temperature and a downstream-side temperature, and calculates the flow rate (mass flow rate) of the hole transporting materialbased 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
