An object of the present invention is to provide a porous material (resin composition) having high heat insulation properties, mechanical properties, and electrical properties by controlling function of a porous film by setting a porosity size, distribution of the porosity size, and a porosity ratio of the porous film in predetermined ranges. The resin composition according to the present invention is comprised of an engineering plastic having porous structure in which not less than 80% of a total porosity is comprised of independent porosities, a mean porosity size is not less than 0.01 &#x3bc;m and not more than 0.9 &#x3bc;m, and not less than 80% of the total porosity has a porosity size within &#xb1;30% of the mean porosity size.

Method for producing a resin composition having a porous structure with independent porosities

A porosity is freely controlled in preparation of a porous polymer film by a phase separation method. A solvent absorption sheet is used for a solvent in a polymer solution so that the coating film of the polymer solution may be covered with the sheet. After that, the solvent in the film is selectively removed. Then, the resultant is immersed in a poor solvent. Thus, a porous polymer film can be produced.

Method of producing porous polymer film and porous polymer film produced by the method

By having multiple air passage holesin the housingand by creating a clearance Gbetween the outer surface of the yokeand the inner surface of the housingthe measurement of the clearance being confined to a range exceeding 0% but not exceeding 2.5% of the inner radius of the housing, the amount of air movement is limited by the clearance Gand by this means the frequency range within which the desired acceleration can be attained is expanded.

The present invention provides a very durable charge injection type light emitting device. In a charge injection type light emitting device comprising a positive electrode, a negative electrode, and an organic film sandwiched between the positive and negative electrodes and composed of one or more organic compounds, the organic film containing at least one light emitting layer, a potential barrier to electrons between the light emitting layer and a barrier layer defined as a member that contacts with the light emitting layer from the positive electrode side is 0.5 eV or more.

Charge injection type light emitting device

An exposure apparatus performs exposure of a photosensitive body by an array of light emitting devices to form an image as a latent image thereon. The array of light emitting devices incorporate micro-optical cavities. The micro-optical cavities limit wavelengths of light emitted from the array of light emitting devices, so that the wavelength at a peak of emitted light is in a half width region of sensitivity versus wavelength of the photosensitive body.
