A metallic honeycomb body for supporting a catalyst comprises a flat plate and a corrugated plate; these plates are formed by a foil of stainless steel in which the steel contains more than 1% of Si and the surface of the steel is covered by a film which is mainly formed by an oxide chrome at a high temperature, and are mutually bonded by diffusion bonding.The chemical composition of the foil material is comprised of up to 0.2% of C, more than 1 to 5% of Si, 9 to 22% of Cr, up to 0.8% of Al, and as necessary, at least one member selected from the group of Nb, V, Mo W and REM (rare earth member) including Y.The metallic honeycomb body is formed by which said body is annealed at a vacuum degree of 10.sup.-2 to 10.sup.-4 Torr and in a temperature range of 1200.degree. to 1300.degree. C. for 1 to 30 minutes in a vacuum annealing furnace.

A metallic carrier composed of an end face portion formed in at least one of the axial end portions of a honeycomb body and an outer circumferential reinforcing layer in which foils in a range from the outermost layer to a quarter of the total number of layers are joined together in the axial intermediate portion. Thus, the metallic carrier is flexible in expansion and shrinkage. Further, the honeycomb body and a jacket are joined to each other mainly at the outer circumference of the outer circumferential reinforcing layer of the honeycomb body, to reduce thermal stress developed between the honeycomb body and jacket while maintaining the strength against a high temperature, to thereby prevent the metallic carrier from being ruptured.

A method of diametrically contracting a cylindrical body, includes the steps of grasping the cylindrical body with a plurality of elongated grasping members, preparing a cylindrical drawing die having an opening at one end and a tapered inside peripheral surface, drawing the grasping members together with the cylindrical body into the drawing die, through the opening, and applying a compression force to the cylindrical body through the grasping members due to the passage along through the tapered inside peripheral surface, to thereby cause the cylindrical body to be diametrically contracted. During the drawing process, since the cylindrical body does not come into direct contact with the drawing die, neither scratches nor baking cracks are produced on the outside surface of the cylindrical body.

A method for cleaning air and an air cleaner utilizing it are disclosed, by which the air cleaner can be made smaller than the conventional air cleaners when the performances are the same. According to the method of the invention, a filter formed on peripheral portion of a disk is formed along the peripheral portion of the disk so as to surround inside area of the disk is rotated, which filter is bent into wave-shape such that irregularities of the wave are formed in radial direction of the disk, thereby discharging air existing on the inside area of the disk to outside of the disk through the filter.

Ion beams drawn out of a plurality of ion beam sources or neutralized beams derived therefrom are projected to a plurality of targets, and sputtered particles discharged from the targets are directed to a substrate. The composition of sputtered particles is measured in the vicinity to the substrate. The measured coomposition is compared with the predetermined reference value and the composition of sputtered particles is controlled based on the result of measurement. sputtered particles having a controlled composition distribution are deposited on the substrate thereby to form a multiple-element thin film.

This invention provides a socket for a circuit board that adds function of electrical resistive element to a contact. A socket includes a socket body extending at a longitudinal direction; and a plurality of contacts disposed in two lines along the longitudinal direction of the socket body. When a memory module is connected to the socket body, terminals formed on opposite surfaces of the memory module are electrically and elastically connected by the contacts. The contact includes a contact portion which contacts the terminal, a bent portion for generating an elastic force, and a base portion. The contact is made of a conductive metal having elastic properties, and the contact used for carrying signal is provided with a resistor of an electrical resistive material that is different from the conductive metal. The resistor is connected in a current path between the base portion and the terminal of the memory module.

A dehumidification apparatus of the type using a deliquescent agent, with which the leakage of deliquesced liquid out of the apparatus is securely prevented is disclosed. In the dehumidification apparatus, an air inlet and an air outlet are formed in the upper plate of the container. At least one closing member which can close the air inlet and the air outlet is arranged above the air inlet and the air outlet. At least one movable member is provided, which has each distal end, which member can move in the vertical direction, which member is attached to the closing member, and which member is urged downwardly such that when the dehumidification apparatus is not placed with its bottom down, the distal end of the movable member protrudes from the bottom of the apparatus so that the closing member closes the air inlet and the air outlet, and when the dehumidification apparatus is placed on a plane with its bottom down, the distal end of the movable member is made flush with the bottom overcoming the downward urging force by virtue of weight of the apparatus so that the air inlet and the air outlet are open.
