  • Patent number: 7406849
    Abstract: A preform with edges overlapped and jointed each other and first and second outer members for forming outer surfaces of a hydroformed product, and reinforcement members that are jointed to the first and second outer members to form reinforcement ribs that divide a hollow cross section of the outer surfaces, the reinforcement members having dimensions capable of suppressing elongation in a tensile direction due to a tensile force that develops during hydroforming.

  • Publication number: 20080135602
    Abstract: A process for manufacturing a honeycomb seal is disclosed. The process includes the following steps: a) the honeycomb structure is brought to the desired three-dimensional form and is fixed in this form; b) then the honeycomb structure is filled with a filler material; c) then the honeycomb structure filled with the filler material is machined on a side on which a carrier element is arranged, such that this side has the desired contour and that the end edges of the honeycomb structure are sealed flushly with the filler compound; d) then the side contoured in this way is coated with a coating; e) next the carrier element is applied to the coating, preferably by laser powder build-up welding.

  • Patent number: 7353980
    Abstract: A method for producing aluminum-containing honeycomb bodies includes providing at least partly structured aluminum-based metal foils. The at least partly structured metal foils are stacked and/or wound to form a honeycomb structure having passages. The metal foils are heated from an open end face of the passages with at least one radiant heater. The honeycomb structure is heated in at least one subregion in such a way that the at least one subregion has a temperature between approximately 450° C. and approximately 600° C. after approximately 2 seconds to approximately 30 seconds. The metal foils are connected together in the at least one subregion by technical joining.

  • Patent number: 7210213
    Abstract: A speaker collective substrate with component insertion hole sections and electrode sections has a plurality of speaker forming areas. An electrical speaker section, which comprises a magnetic circuit section and a vibration section, is inserted into each of the component insertion hole sections. Then, a collective lid, in which a plurality of lids have been formed for sealing the electrical speaker sections, is attached onto the speaker collective substrate. After that, the speaker collective substrate and the collective lid are divided into individual speaker forming areas along partition lines extending in the directions of the X and Y axes to form individual dynamic speakers. Thus, it is possible to mass-produce dynamic speakers with uniform quality through a collectively manufacturing process.

  • Patent number: 7197822
    Abstract: A honeycomb structure includes a plurality of substantially parallel channels, a layer of at least partially structured metal foils and a housing. The layer includes a number N of at least partially structured metal foils and a number N+1 of smooth metal foils. The number N=1, 2 or 3 and two of the smooth metal foils are exterior foils. A method for producing such a honeycomb structure is also provided. The honeycomb structure is used, in particular in exhaust gas systems of mobile internal combustion engines.

  • Patent number: 7124496
    Abstract: A head suspension for a disk drive has a base plate (19) to be attached to a carriage of the disk drive and a load beam (21) consisting of a rigid part (27) and a resilient part (29), to apply load onto a slider. The rigid part and resilient part are separately formed. The rigid part is joined to a first side (29a) of the resilient part. The suspension also has a reinforcing plate (37) to hold and fix a second side (29b) of the resilient part between the reinforcing plate and the base plate. The base plate stably and resiliently supports the load beam. This suspension satisfies required characteristics.

  • Patent number: 7111393
    Abstract: A metal honeycomb body that is particularly suited for use in an exhaust system of an internal combustion engine is prepped for receiving a sensor that reaches into the interior of the honeycomb body. First, voids such as recesses and/or elongated holes are formed in at least one sheet metal foil. Then some of the foils are at least partially structured, as for example corrugated. Then the foils are stacked, coiled, wound, or otherwise made into a honeycomb structure, with the at least one sheet metal foil disposed to form a receiver that extends into the interior. The honeycomb structure is then inserting into a sheathing tube that is formed with an opening that is aligned at least partly with the receiver. Then the various pieces are joined by way of a suitable joining technique. The novel method prevents the channels from being damaged during manufacture when receivers for sensors are subsequently produced and allows, for example, an especially effective conversion of exhaust gases.

  • Patent number: 7108168
    Abstract: A method for gluing and brazing a honeycomb structure includes at least one partially structured foil with a pitch and a wave height. The method includes the steps of choosing a mean brazing material diameter of a powder brazing material, said diameter being 15% smaller than the height of the wave; determining a minimum thickness of the glue strip according to equation; gluing at least partially structured foil within the width of the glue strip on at least part of the wave crests formed by the undulation; brazing the honeycomb structure. The invention also relates to a corresponding honeycomb structure that ensures satisfactory joint connections even when said structure is used in the exhaust systems of automobiles.

  • Patent number: 6915555
    Abstract: A method of manufacturing a loudspeaker comprises: continuously forming diaphragm portions and alignment portions on a band resin film; positioning one of a frame and a protector at an upper die or lower die; aligning other alignment portions formed on the frame, the protector, or the upper or lower die having the film disposed thereon, with the alignment portion formed on the film; bonding the frame and the resin film that is to form the diaphragm; and cutting a diaphragm out of the resin film. A position of bonding the diaphragm to the frame or the protector can be easily determined by aligning the alignment portion formed on the band resin film with another alignment portion provided on the frame, the protector, or the lower or upper die on which the frame or protector is disposed. Further, a conventionally-indispensable ring can be eliminated to reduce a number of components.
