Provided is a method of producing a catalyst or adsorbent carrier and a catalyst or adsorbent carrier which can enhance a catalyst or adsorbent function, and prevent fall-off of catalyst particles or adsorbent particles. The surface of a metal base material made of aluminum or an aluminum alloy is subjected to an etching process using an etchant containing iron chloride and an oxide to convert the surface to an uneven and rough surface. The uneven and rough surface of the metal base material is subjected to an anodizing process to form a porous coating along the uneven and rough surface. A large number of catalyst or adsorbent particles are thus carried on the surface of the metal base material on which the porous coating is formed along the uneven and rough surface.

Method of producing catalyst or adsorbent carrier, and catalyst or adsorbent carrier

In a photocatalytic device, a photocatalytic filter is formed of a corrugated member and a gas is allowed to flow over front and rear surfaces of the filter from one end toward the other end thereof along a direction in which ridges and valleys extend, and a gas inflow part and a gas outflow part are provided at both end positions of a photocatalytic filter instead of providing a gas inlet-side flow channel and a gas output-side flow channel at positions facing filter surfaces. Thus, a contact area between a gas and the filter surfaces can be maintained, and miniaturization of the device such as reduction in the thickness or diameter can be realized without increasing gas circulation resistance. In addition, enhanced light irradiation efficiency, simplified structure, energy saving, and cost reduction can be realized. Moreover, the problem of heat can be solved.

Photocatalytic device

A photo catalytic filter is configured such that a plurality of plate-shaped members on which a photocatalyst is carried face each other with a gap therebetween, and the gaps form an air flow path. Each plate-shaped member has end surfaces respectively on an air entrance side and an air exit side of the gap. A UV irradiation unit faces the end surfaces on at least one of the air entrance side and the air exit side of the plate-shaped members, and is a predetermined distance away from those end surfaces. An air supply path for taking air from a lateral direction substantially parallel to the end surfaces, and supplying the air to the flow path, or an air discharge path for discharging the air exiting the flow path to a lateral direction substantially parallel to the end surfaces, is formed between the UV irradiation unit and the end surfaces of the plate-shaped members.

Provided is a photocatalytic device capable of further enhancing an effect by a photocatalyst and also efficiently dissipating heat emitted from a light applying portion, and capable of further enhancing the purification effect by increase of a light amount. In the photocatalytic device, both end portions of a housing in the lateral direction are in contact with an upper face of a photocatalyst filter to support the photocatalyst filter, and form upper-side edge portions for openings. A center portion of the housing is distant from the photocatalyst filter in an upward direction. Tilted portions are positioned in regions between both the end portions and the center portion. A lower-side inner wall of the housing supports the photocatalyst filter, and forms lower-side edge portions for the openings. A light applying portion is disposed on a lower face of the center portion of the upper-side inner wall.

Method for manufacturing a caulked assembly

There is provided a lighting device excellent in mass productivity and capable of significantly reducing a production cost and allowing easy provision of a light-weight and large-size lighting device as well as improving a degree of freedom in choosing materials and exhibiting an adequate heat dissipation effect. A heat dissipation portion is obtained by press-working a metal plate. For example, the heat dissipation portion is configured by press-deforming the metal plate into a substantially dome-like shape having a vertically extending peak portion and a vertically extending valley portion that are peripherally and consecutively formed, by repeatedly bending the metal plate along a circumferential direction into a wave shape and concurrently warping the metal plate in an axial direction such that the outer peripheral side of the metal plate is positioned closer to the tip in the axial direction than the central side thereof.

The present invention provides a caulked assembly to be manufactured at low cost, and maintain sufficient caulking strength, and the manufacturing method and apparatus thereof. The manufacturing method comprises steps of forming a mounting hole for inserting and assembling a columnar body in a metal plate body, and forming a thick part along an inner circumferential edge of a mounting hole; forming a circumferential groove with a predetermined depth at an assembled position of a outer circumferential surface of the columnar body inserted into the mounting hole; inserting the columnar body into the mounting hole to set to the assembled position where the thick part is opposed to the circumferential groove; and caulking for compressively pressing the thick part from an axial direction of the columnar body to plastically deform the thick part in a center direction of the mounting hole to bite the thick part into the circumferential groove.
