Patent TW-434184-B (TW)
Title: Method for production of aluminum nitride powder
Inventor: JUNG SHIAN-LUNG
IPC: C01B21/072
Filed: 1997-11-24
Granted: 2001-05-16
Abstract: This invention concerns a method for production of AIN powder. The reactants discovered in the invention are aluminum powder and a compound which contains NHX (e.g., NH2, NH3, NH4, N2H4 and N2H6) or halogen and which can be thermally decomposed or vaporized below the melting point of Al (660 DEG C). These two reactants are mixed at an appropriate ratio and then pressed into a compact with an appropriate shape. These two reactants, after being mixed at an appropriate raito, may also be placed in a refractory container which has an opening at one end or has porous walls. This reactant compact or reactant mixture is then placed in a reaction chamber which is filled with nitrogen. By heating the reactant compact or the reactant mixture at one end, the combustion synthesis reaction is ignited and AIN powder is produced. The compound decomposes or vaporizes during being heated, thus creating numerous pores in the reactant compact or the reactant mixture. The nitrogen thus flows easily into the reactant compact (or the mixture) to react with Al. Besides, the halogen can catalyze the nitridation of Al and the NHx may attack easily the Al, thus promoting the nitridation reaction. AIN powder with high purity can therefore be produced under low nitrogen pressures (1-10 atm).

Title: Cache coherent network adapter for scalable shared memory processing systems
Inventor: OLNOWICH HOWARD THOMAS
IPC: G06F19/00
Filed: 1998-03-09
Granted: 1999-06-11
Abstract: A shared memory parallel processing system interconnected by a multi-stage network combines new system configuration techniques with special-purpose hardware to provide remote memory accesses across the network, while controlling cache coherency efficiently across the network. The system configuration techniques include a systematic method for partitioning and controlling the memory in relation to local verses remote accesses and changeable verses unchangeable data. Most of the special-purpose hardware is implemented in the memory controller and network adapter, which implements three send FIFOs and three receive FIFOs at each node to segregate and handle efficiently invalidate functions, remote stores, and remote accesses requiring cache coherency. The segregation of these three functions into different send and receive FIFOs greatly facilitates the cache coherency function over the network. In addition, the network itself is tailored to provide the best efficiency for remote accesses.

IPC: H04N19/42
Filed: 1999-07-13
Granted: 2001-12-01
Abstract: In the case where an output signal of an image pickup device is compressed and is transmitted through a transmission path with band limitation, when a conventional compression and expansion technique is directly applied, there is a lot of waste and a circuit scale becomes large, so that the cost of the system is raised. In an image processing system of a camera system of the invention in which an output signal of an image pickup device is compressed and is transmitted, the output signal of the image pickup device is made to pass through a luminance signal forming portion and a contour correcting signal forming portion, so that the signal is divided into a luminance signal and a contour correcting signal. These signals are separately compressed by compression processing portions, and multiplexed by a multiplexing portion, and then transmitted through a transmission path with band limitation such as a USB.

Title: Piston for internal combusiton engine
Inventor: TAKE KAZUHIDE
IPC: F02F3/02
Filed: 2000-01-24
Granted: 2001-05-01
Abstract: An object of the present invention is to effectively achieve the reduction in piston slap sound in both of an expansion stroke and a compression stroke in consideration of a difference between the behaviors of a piston in the expansion stroke and the compression stroke. For this purpose, in a piston P having a skirt 12 formed into an intermediately bulged barrel type, the axis L2 of a piston pin is offset with respect to the cylinder axis L1, and the decrement in radius of a lower skirt portion 20 is set to be large on a thrust side and small in an anti-thrust side. In the expansion stroke, the piston is positively swung, while the skirt 12 is put into abutment against a wall surface of a cylinder bore, thereby reducing the piston slap sound. In the compression stroke, the angle of swinging movement of the piston provided upon abutment of a lower end of the skirt 12 against the wall surface of the cylinder bore is suppressed to a small level, and the piston slap sound generated by the subsequent swinging movement of the piston in an opposite direction is reduced.

Title: Iridium conductive electrode/barrier structure and method for same
Inventor: ZHANG FENGYAN
IPC: H01L27/10
Filed: 2000-03-03
Granted: 2001-06-16
Abstract: A conductive barrier useful as a ferroelectric capacitor electrode, having high temperature stability has been provided. This conductive barrier permits the use of iridium (Ir) metal in IC processes involving annealing. Separating silicon substrate from Ir film with an intervening, adjacent, tantalum (Ta) film has been found to very effective in suppressing diffusion between layers. The Ir prevents the interdiffusion of oxygen into the silicon during annealing. A Ta or TaN layer prevents the diffusion of Ir into the silicon. This Ir/TaN structure protects the silicon interface so that adhesion, conductance, hillock, and peeling problems are minimized. The use of Ti overlying the Ir/TaN structure also helps prevent hillock formation during annealing. A method of forming a multilayer Ir conductive structure and Ir ferroelectric electrode are also provided.
