There is provided an applicator that applies a coating liquid onto the upper surface of a web, and an application method which are capable of sufficiently enhancing the evenness of a coating surface. The applicator includes: a bar which rotates while coming into contact with the upper surface of the continuously travelling web via the coating liquid; and a barrier plate which is provided on an upstream side of the bar in a travelling direction of the web and allows the coating liquid to flow in a direction toward the web between the barrier plate and the bar, in which, when a distance between the barrier plate and an end edge portion of the bar, which is closest to the barrier plate, is referred to as A and a distance between the barrier plate and the web is referred to as B, A is 0.5 mm to 5 mm, B is 0.5 mm to 5 mm, and B&#x2264;A is satisfied.

Applicator and application method

A biochemical analysis unit comprises a base plate, which has holes, and a porous adsorptive material, which is filled in each of the holes and forms each of adsorptive regions. Each of the adsorptive regions is provided with a layer, which has pores having a comparatively small mean pore diameter, and a layer, which has pores having a comparatively large mean pore diameter. In cases where the layers, which constitute each of the adsorptive regions, are connected with the layers, which constitute an adjacent adsorptive region, at one of surfaces of the base plate, the biochemical analysis unit further comprises a signal absorbing layer for absorbing a signal, which passes through layers located under the base plate and thus propagates from a certain hole toward an adjacent hole.

Biochemical analysis unit

A continuous substrate and a continuous absorptive sheet are fed to a press station, and pressed continuously or intermittently. Part of the continuous absorptive sheet is charged in plural holes formed in the continuous substrate to form a biochemical analysis sheet. The biochemical analysis sheet is cut into predetermined tips to obtain a biochemical analysis unit.

Method for producing biochemical analysis unit

In producing a biochemical analysis unit (), an adhesive agent () is applied to a base. After calcinations, the adhesive agent () forms an adhesive layer () on a wall of each holes () formed in the base (). Thereafter, an excess adhesive agent () remaining on the surface of the base () is removed. Then, a sheet of an absorptive material () is set to overlap the base (). A press roller pair () presses them to charge the absorptive material () in the holes (). Thus the absorptive material () is fixed in the hole () of the base () through the adhesive layer ().

Biochemical analysis unit and method for producing thereof

The biochemical analysis unit has a base plate and absorptive regions. The absorptive regions are surrounded by the base plate formed of materials which shield a radioactive ray and a light. In the absorptive regions are applied and absorbed specific binding substances to be bound with substances derived from a living organism that are labeled with labeling substances for generating the radioactive ray or the light. The base plate prevents the specific binding substances from penetrating in the other absorptive regions. When an analysis of data of the radioactive ray and the light is carried out, an image of the radioactive ray and the light is generated without noises.

In the case where multiple slide hopper is used for simultaneous multilayer bead coating of photosensitive material, streak defect is occasionally cause, particularly in the case of coating photothermographic material, especially when the outermost layer includes materials capable of increasing optical density such as toner it more frequently happens. It is found that streak defect is restrained when meniscus curvature of upper side bead becomes less than 7.2 mm . This condition can be kept by selecting a proper value of clearance between the web surface and the lip of the slide hopper, that is from 0.10 mm to 0.40 mm, and a proper value of pressure in a lower side of the bead, that is from &minus;100 Pa to &minus;700 Pa.
