Abstract: A reflective or transmissive image display device having a light-transmissive panel to which illuminating light for illuminating pixels is applied. The light-transmissive panel has laminated glass substrates having respective first and second planar microlens arrays. The glass substrates have their thicknesses adjusted by grinding to equalize focal lengths and other parameters of the first and second planar microlens arrays to preset values. Lenses of the first and second planar microlens arrays are formed by etching recesses in fire-finished surfaces of the glass substrates and filling the recesses with a synthetic resin having a high refractive index.

Abstract: An air conditioner having an improved humidifying portion to humidify air in a room is provided. The humidifying portion includes a humidifying member having hygroscopicity and gas permeability, a first air flow passage for taking in air from the outdoors, passing the air through the humidifying member, allowing the humidifying member to absorb moisture included in the air for drying, and letting out the air outdoors, and a second air flow passage for taking in air from the room, passing the air through the humidifying member while heating the air, allowing the moisture absorbed by the humidifying member to evaporate and humidify the air and letting out the air into the room. Thus, only a single air intake opening for humidifying indoor air is necessary on the indoor side, the structure of the air conditioner can be simplified and compact, which makes easier the attachment.

Abstract: The improved illuminating apparatus comprises a spheroidal mirror, a light source, a spherical mirror and a condenser lens. The spheroidal mirror has such a shape that it is deficient of a portion that would otherwise reflect light that illuminates any portions other than the object to be illuminated, and that the light from the light source which is directed toward said missing portion is reflected by the spherical mirror positioned on the rear side of said missing portion as seen from the light source and makes another reflection by that part of the spheroidal mirror which faces away said missing portion, thereby illuminating the object. The light source is positioned at the first focal point of the spheroidal mirror in such a way that it faces the mirror, and the spherical mirror is positioned in such a way that its reflecting face lies at the second focal point of the spheroidal mirror.

Abstract: This invention relates to a method for manufacturing an inorganic porous layered member which can maintain a sufficient distance between layers to show a high degree of heat insulating properties. In the manufacturing method for the inorganic porous layered member according to the present invention, an inorganic layered compound 12 having swelling charecteristics is swelled, and an inorganic pillar and an organic pillar are intercalated to form inorganic compound 16 between layers 14 of the inorganic layered compound 12. Fine gaps are thus formed in a wide range by the intercalation of the inorganic compound 16 between the layers 14 to maintain a sufficient distance between the layers 14, and the inorganic porous layered member 10 having high heat insulating properties is thus produced.

Abstract: A projection-type image display device includes a transmissive image display panel having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array for converging light emitted by a light source onto the transmissive image display panel. The planar microlens array comprises a substrate and a matrix of microlenses disposed on the substrate for converging the light onto the pixels, respectively, each of the microlenses being of an oblong shape. Each of the microlenses may have a longitudinal axis inclined with respect to an axis of the matrix of pixels to cover the pixel aperture of one of the pixels. The oblong shape of each of the microlenses may be composed of a pair of spaced identical semicircles and a rectangle interconnecting the identical semicircles and having sides of the same length as the diameter of the semicircles.

Abstract: A method for manufacturing a fine porous member provides that vacant space within the porous member is sufficiently finely small such that the thermal conductivity of the member is lower than that of stationary air. In the method, a fine particle powder together with an ultrafine particle powder preliminarily subjected to a surface treatment for prevention of cohesiveness and employed at least as a part of the fine particle powder, are molded into the fine porous member, whereby the vacant space between the respective particles are made finely small to a remarkable extent and the porous member is provided as highly adapted to be used as a heat insulator.
