SHIELD MOLDING BLANK AND SHIELD
Provided is a shield molding blank which has an uneven structure in which an air gap 4 is formed between metal plates 2, 3 formed in overlapping wavy shapes comprising recesses and projections that are periodically continuous in two directions orthogonal to each other, the shield molding blank being cut in a desired expanded shape and having peripheral edges folded. With the shield molding blank, it is possible to mold a shield having improved shield characteristics such as a heat-shielding property and a sound-shielding property.

HEAT EXCHANGER
A brazed plate heat exchanger (100) for exchanging heat between at least two fluids comprises several elongate heat exchanger plates (110) provided with a pressed pattern comprising depressions and elevations adapted to keep the plates on a distance from one another by contact points between the elevations and depressions of neighboring plates under formation of interplate flow channels for media to exchange heat. At least four port openings are placed in corner regions of the elongate heat exchanger plates and have selective fluid communication with the interplate flow channels such that the fluids to exchange heat will flow between port openings parallel to long sides of the elongate heat exchanger plates. A circumferential seal sealing off the interplate flow channels from communication with the surroundings is provided, and the heat exchanger plates are joined by brazing. The circumferential seal results partly from contact between skirts of neighboring plates contacting one another, said skirts extending at least partly along two sides of each heat exchanger plates, and partly from contact between flat areas extending along two other sides of the heat exchanger plates.
Profiles
An elongate profile (1) having a first portion (2) and a second portion (3), the first and second portions (2, 3) being joined together at a first joining portion (JP1), the first and second portions (2, 3) being non collinear, the joining portion (JP1) comprising an array of raised or rebated formations (10a), each formation extending across the joining portion (JP1) in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array (10A) and the pitch (P) between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness (G) of the flatlands.

Stamping device
A stamping device has: a die seat that a metal sheet, as a workpiece, abuts; and a stamping punch configured to stamp a character to be stamped onto a front surface of the metal sheet by pressing the stamping punch onto a stamped region of the metal sheet from the front surface side of the metal sheet. A stamp-receiving region that corresponds to the stamped region is provided on a front surface of the die seat, and, in this stamp-receiving region, plural dents are provided in such a manner as to correspond to the stamped region of the single character to be stamped.

METAL CATALYST SUPPORT, MANUFACTURING METHOD AND APPARATUS THEREFOR
Provided is a method of manufacturing a metal catalyst support including: transferring a plate member of the same size along a transfer unit; aligning the plate member so that a front portion of the plate member is located at a start point when the plate member reaches a set position; forming a corrugated plate by alternately forming a first corrugated portion and a second corrugated portion on the plate member which is aligned at the start point; and laminating the fabricated corrugated plates and the flat plates alternately in a case.

Metal catalyst support, manufacturing method and apparatus therefor
Provided is a metal catalyst support including: a case having a space through which exhaust gas passes; and flat plates and corrugated plates which are alternately stacked in the case and coated with a catalyst, wherein the corrugated plates are formed such that a first corrugated plate and a second corrugated plate are disposed with the flat plate therebetween, the first corrugated plate and the second corrugated plate are disposed such that a first corrugated portion and a second corrugated portion are alternately and repeatedly formed, and the vertex of the first corrugated portion and the vertex of the second corrugated portion face and coincide with each other, to thereby minimize deformation during thermal expansion due to external impact, vibration and temperature change.
