摘要:
The present invention provides a method for controlling the spatial arrangement of an energy donor and an energy acceptor in a reaction complex in order to carry out the measurement with good precision and high sensitivity, and a measurement system using the method. Two types of material having affinity for the subject material to be measured are respectively labeled with a combination of reporters that give rise to energy transfer; those that have been thus obtained by labeling these materials are each further labeled with materials that have weak affinity for each other to give reagents, which are then mixed with a sample to give the reaction complex. Each of the materials is brought into spatial proximity by binding based on the affinity among the materials having weak affinity for each other in the reaction complex, and since that condition is stably maintained, a more efficient energy transfer occurs.

A pattern film forming method includes a step of producing a transfer sheet in which a thin film is formed on a surface of a sheet-shaped material and a step of pressing the thin film against a pattern film formation surface of the substrate with a pressing member having convex portions corresponding to the pattern film from a reverse surface of the transfer sheet opposite to the thin film or a reverse surface of the substrate opposite to the pattern film formation surface to transfer the thin film to the substrate. A pattern film forming apparatus includes a sheet supply device, a pressing device and a substrate transport device. A high-definition pattern film having a desired pattern and a sharp edge can be formed with high productivity.

A pressure gauge adapted for use in measuring the pressure of a thixotropic fluid subject to aggregation stagnation in which aggregation of the fluid is prevented by controlling stagnation of a magnetic coating liquid in the vicinity of a pressure sensor, and product quality is improved by removing air mixed into the liquid. An outlet is formed at the vertex of a conical holder. An inlet is formed in the conical surface of the holder at a location offset from the center of the cone defining the holder, which is contained in the outlet. A pressure indicator is mounted in the opening portion in the plane of the cone defining the holder.
摘要:
A method for producing a magnetic recording medium wherein an undercoating layer is provided before forming a magnetic layer by applying a coating composition onto a surface of a continuously traveling flexible support, excluding widthwise-direction edge portions of the support, and pressing the support to a forward end of a slot of a coating head. At least one part of the undercoating layer is formed by preliminarily applying a high-molecular solution having a glass transition point of higher than the heat treatment temperature onto at least the edge portions of the flexible support to give a larger width to the undercoating layer than the width of the magnetic coating layer.

A method for producing a magnetic recording medium in which widthwise deviations in thickness of coating caused by widthwise unevenness of the support being coated are suppressed so that the coating thickness is made uniform. An extrusion-type coating head is used for coating, and a magnetic coating composition is continuously extruded from a top end portion of a slit of the coating head onto the surface of the support while the support is running continuously along a back edge surface and a curved doctor edge surface having a curvature thereby to coat the surface of the support with the magnetic coating composition, the method being characterized in that coating is carried out in such manner so that the following condition is satisfied:12.mu. (m/d.sup.3)Ut>0.20(T/R)where.mu.: composition viscosity (poise)m: slit length (mm)d: clearance of the slit (mm)U: coating speed (m/sec)t: coating thickness (.mu.m)T: tension at a coating portion (kgf/whole width)R: radius of curvature of the doctor edge (mm).

摘要:
An application device capable of very rapidly applying a liquid in the form of a thin film to a continuously moving flexible carrier in such a manner as to avoid corrosion and wear to the surface of the doctor edge portion of the application device to thus avoid the formation of streaks on the surface of the applied liquid. A clearance between the surface of the carrier and the surface of the doctor edge portion is made larger at the downstream end of the surface of the doctor edge portion than at the upstream part thereof. For this purpose, a support roller is provided near the downstream end of the surface of the doctor edge portion so that the clearance between the surface of the doctor edge portion and the surface of the carrier can be appropriately controlled along substantially the entire width of the doctor edge portion by adjustably displacing the roller. Application is performed while the clearance between the surface of the carrier and the doctor edge portion is set larger at the downstream end of the surface of the doctor edge portion than at the upstream part of the surface thereof.

A coating system for applying a coating solution to a web includes a coating device for applying the coating solution to the web as it moves past the coating device, a doctor blade having a curved end face which corresponds to the curved configuration of the web as it moves past the end face. The end face of the doctor blade serves to scrape off any excess amount of coating solution applied to the web by the coating device.
