Title: Heat exchanger
Inventor: RITTBERGER HERBERT
IPC: F28D9/00
Filed: 2000-12-14
Granted: 2010-12-07
Abstract: A heat exchanger for exchanging heat between a cooler first air flow and a warmer second air flow is disclosed. The heat exchanger comprises a heat exchanger unit having a housing containing a plurality of heat exchanger plates stacked together to form a stack. Each heat exchanger plate has four corners and an aperture located adjacent each corner, the heat exchanger plates being dimensioned and configured such that the apertures of the heat exchanger plates overlap to form a first, second, third and fourth air passageways in the stack. The heat exchanger plates are further configured to form an alternating series of first and second flat parallel air chambers in the stack, the first set of air chambers being continuous with the first and second air passages such that air can pass between the first and second air passages through the first set of air chambers, the second set of air chambers being continuous with the third and fourth air passageways such that air can pass between the third and fourth air passageways through the second set of air chambers. The stack of heat exchanger plates are further configured such that the first and second set or air chambers are substantially air tight such that air does not leak between the first and second set of air chambers. The heat exchanger unit has a first and second side, the first, second, third and fourth air passageways each having a first end open to the first side of the heat exchanger unit at a first port and an opposite second end opened to the second side of the heat exchanger unit at a second port. The stack is further adapted such that each port may be selectively plugged by a plug member, the heat exchanger unit having four plug members, each plug member plugging one end of each air passageway.  Finally, the first, second, third and fourth air conduits, are each operatively coupled to one of the air passageways, the air conduits carrying the first and second air flows.

Abstract: L'invention concerne un procédé de détection de trames de données dans une fonction de transport. Ce procédé consiste à comparer un compteur de séquences de trames avec une valeur de seuil prédéterminée (304), à détecter une trame différée si le compteur de séquences dépasse la valeur de seuil et à traiter la trame différée en conséquence (306). Dans un protocole de transport de données RLP, la trame différée peut être traitée comme une trame retransmise. La valeur de seuil peut être proportionnelle au nombre maximum de trames envoyées dans un faisceau multiplié par le retard maximum, en unités d'intervalles de trame, entre des trames envoyées simultanément sur voie radio dans le même intervalle de trame.

Filed: 1998-12-28
Granted: 2005-04-12
Abstract: The present invention relates to a three-dimensional skeleton data compression apparatus for compressing a skeleton data amount without degrading rendering quality of a three-dimensional object. A weight detecting part detects weight information that is a numerical value obtained from input skeleton data, showing a degree of the influence of the movement of a skeleton on a vertex, and a weight compressing part deletes a value equal to or lower than a predetermined threshold value. The skeleton compressing part conducts first skeleton compression with respect to a skeleton having no polygon vertex in which an effective weight value is set. The skeleton compressing part also detects relative movement between skeletons, and second skeleton compression is performed to reduce/integrate a skeleton group integrated without relative movement into a unified skeleton. If required, masks are put on skeletons that are not to be subjected to skeleton compression. A polygon file is generated based on compression skeleton data, model information of a polygon and a texture, and scenario information.

Title: A method of manufacturing a metal pipe with an eccentrically expanded open end
Inventor: ISHIKAWA HANJI
IPC: B21D41/02
Filed: 2001-09-24
Granted: 2005-09-13
Abstract: At first, an open end of an original metal pipe M is plastically deformed to such the coaxially expanded state M1 that axial wall length L2 at a side to be eccentrically expanded is longer than axial wall length L1 at the opposite side to be expanded without eccentricity. The coaxially expanded open end M1 is then plastically deformed to an eccentrically expanded state M2 by forcibly inserting an eccentrically expanding punch 20 into the coaxially expanded open end M1. The eccentrically expanding punch 20 has a boundary 23 between a conical tip 21 and a cylindrical body 22 inclined with a predetermined angle .theta. so as to bring the cylindrical body 22 into contact with an inner wall of the coaxially expanded open end M1 at a side to be eccentrically expanded earlier than the opposite side to be expanded without eccentricity. When the coaxially expanded open end M1 is plastically deformed to an eccentrically expanded state M2, metal flow is suppressed at a side to be eccentrically expanded, but metal flow from the opposite side to be expanded without eccentricity to the former side is promoted. Consequently, the open end is plastically deformed to the eccentrically expanded state M2 without thickness deviation along a circumferential direction.

Title: Executing native code in place of non-native code
Inventor: BARCLAY BRAD J
IPC: G06F17/00
Filed: 2002-03-12
Granted: 2009-04-28
Abstract: A code execution mechanism is provided which can direct a data processing system to execute native code in place of executing non-native code, in which the native code is functionally equivalent to the non-native code. The data processing system is operatively coupled to a computer readable memory for storing the functionally equivalent native code and for storing the non-native code. The code execution mechanism directs the data processing system to identify presence of the native code when the native code functionally corresponds with a portion of non-native code, and directs the data processing system to execute the native code in place of the non-native code if the presence of the native code is identified. When non functionally equivalent native code is identified, the data processing system executes the non-native code.
