Title: Design analysis method of earthquake-proof reinforcement structure, and storage medium
Inventor: TACHIKAWA TAKASHI
IPC: G06F17/50
Filed: 2001-12-12
Abstract: A member of an earthquake-proof reinforcement structure is selected with reference to the allowable stress intensity ratio of the member, a ductility factor ratio allowable as a deformation magnification by earthquake-proof reinforcement of the selected member is set, an increase in load in a plasticity range, which acts on the selected member, is calculated on the basis of the set ductility factor ratio, and a corresponding allowable stress intensity ratio is obtained. When the obtained allowable stress intensity ratio is defined as a maximum value of 1.0, the corresponding increase in load in the plasticity range is specified as an ultimate load at which the selected member collapses.

Patent CA-2366832-A1 (CA)
Inventor: MACMILLAN WILLIAM ROBERTSON
IPC: B24C5/06
Filed: 1991-07-02
Abstract: An abrasive throwing wheel assembly comprises a throwing wheel having parallel annular side plates joined by spacers with the facing surfaces of the side plates having angularly-spaced registering throwing blade locating slots and throwing blades with lateral rails or edges for location in the slots.  The side wheels slots are wider than is customary and contain central radially-extending projections. The lateral rails or edges of the throwing blades are grooved from the tips inwardly for at least part of their lengths. The throwing blades are located by interengagement between the sidewall projections and the rail or edge grooves of the blades. This reduces the surface contact between the blades and the side plates with consequent reduction in the accumulation of jamming abrasive during use. Throwing blade removal is thus facilitated. The wider slots remove the narrow radial flow of high velocity abrasive or shot between the slot walls and throwing blade side rails or edges which is customary thus reducing side plate, especially side plate rim, wear.

Title: Self-guiding punch and die set
Inventor: SCHROTH MICHAEL
IPC: B21D28/14
Filed: 2000-05-23
Abstract: A punch and die set (1) is provided for use in a stamping press (10) having a punch assembly (100) and a die assembly (200) reciprocated by a driving mechanism (25, 30, 35, 37, 38). The punch and die assemblies are aligned to a common center (50) and are structured to slidably engage one another for positive guidance of the punch and die tools without the need for other guidance by shafts, bars or the like. One of the punch assembly and die assembly can be non-fixedly carried by the drive mechanism, allowing the guidance of the engaged punch and die assemblies to define the relative positions of the tools. This arrangement eliminates any stack-up of tolerances between the assemblies and substantially reduces misalignment during stamping, including any misalignment that may be introduced by the press driving mechanism.
Patent CA-2374082-A1 (CA)
Title: Flexible stent
Inventor: MAJERCAK DAVID C
IPC: A61F2/06
Filed: 2002-03-01
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent.   Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.

Abstract: A multiple CAM chip architecture for a CAM memory system is disclosed. The CAM chips are arranged in a diamond cascade configuration such that the base unit includes an input CAM chip, two parallel CAM chip networks, and an output CAM chip. The input CAM chip receives a CAM search instruction and provides the search instruction and any match address simultaneously to both CAM chip networks for parallel processing of the search instruction. Each CAM chip network provides the highest priority match address between the match address of the input CAM chip and its own match address. The output CAM  chip then determines and provides the highest priority match address between the match addresses of both CAM chip networks and its own match address. Each CAM chip network can include one CAM chip, or a plurality of CAM chips arranged in the base unit diamond cascade configuration. Because the clock cycle latency of the diamond cascade configured CAM memory system is determined by sum of the inherent CAM chip search latency and the number of parallel levels of CAM chips, many additional CAM chips can be added to the system with a sub-linear increase in the system latency.
