摘要:
The present invention provides a method for producing an optical member including the steps of subjecting a surface of a resin film to laser beam irradiation via a projection mask,.while sequentially moving either the resin film or the projection mask, or the both, and etching the resin film plural times to work into the shape of a lens, wherein the projection mask comprises plural light-transmitting parts or light-shielding parts having gradually different sizes; and a method for producing a molding die for the optical member. The method for producing an optical member and the method for producing a molding die for an optical member can be suitably used in, for example, a microlens sheet, a light-condensing sheet, a light-diffusing sheet, or the like.

Disclosed is a method for easily producing a long porous thermosetting resin sheet which has no resin coating film on the surface. Also disclosed are a porous thermosetting resin sheet produced by the method, and a composite semipermeable membrane having excellent chemical resistance and practical water permeability and salt-blocking property. The porous thermosetting resin sheet can be produced by forming a cylindrical or columnar resin block which is composed of a cured product of a thermosetting resin composition containing a thermosetting resin, a curing agent and a porogen; then forming a long thermosetting resin sheet by cutting the surface of the resin block at a certain thickness; and then removing the porogen from the thermosetting resin sheet.

It is an object of the present invention to provide a composite semi-permeable membrane exhibiting excellent chemical resistance and having practical water permeability and salt-blocking property, and a method for producing the same. The present invention relates to a composite semi-permeable membrane, including a porous support and a skin layer formed on a surface of the porous support, wherein the porous support contains a thermosetting resin porous sheet having a three-dimensional network structure and pores communicating with each other and wherein the thermosetting resin porous sheet has an average pore diameter of 0.01 to 0.4 μm.

A method and apparatus for accessing content is capable of retrieving and selecting information is facilitated by using uniform operations. Symbols corresponding to pre-recorded programs contained on a recording medium are displayed on a screen. In response to selecting one of the symbols, representative frames comprising the program are displayed on the screen. In response to selecting a representative frame, a portion of the program is played back. In a recording device, content is accessed by displaying a representative frame from each of a number of user-defined streams. At least a portion of a stream is played back in response to selection of the corresponding one of the representative frames.

The present invention provides a method for producing a separator for nonaqueous electrolyte electricity storage devices. The method allows: avoidance of use of a solvent that places a large load on the environment; and relatively easy control of parameters such as the porosity and the pore diameter. The production method of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; removing the porogen from the epoxy resin sheet by means of a halogen-free solvent so as to form a porous epoxy resin membrane; and drying the porous epoxy resin membrane by heat-roll drying.

Disclosed are a fertilizer containing a sparingly water-soluble phosphatic fertilizer and an urea/aliphatic aldehyde condensation product. The process for controlling inorganizing speed of urea/aliphatic aldehyde condensation product comprises adding to the urea/aliphatic aldehyde condensation product a sparingly water-soluble phosphatic fertilizer having special elution characteristics. The fertilizer of the invention and the process for controlling inorganizing speed of urea/aliphatic aldehyde condensation product of the invention make it possible to control the inorganizing speed of the condensation product without changing the particle size or form. The fertilizers of the invention or the urea/aliphatic aldehyde condensation products can provide nitrogen components to plant in accordance with the periods of culture of desired crops and a pattern of absorbing nutrition. This is effective in saving of the number of additional fertilization or nitrogen components left in soil after the period of culture.
