IPC: B24D3/00
Filed: 1999-02-25
Granted: 2001-05-01
Abstract: A wire saw has a small diameter metal wire and a layer of abrasive grains firmly affixed to the wire surface by a brazed or soldered active metal bond. Preferably, the grains are present in a single layer. The grains are disposed on the surface of the wire in a preselected surface distribution. The wire saw can be made by a completely continuous process involving coating the wire with a paste of metal bond powder components combined with a fugitive liquid binder component. Abrasive grains are deposited into a layer of the paste. Thereafter, the bond composition is fused at elevated temperature to braze the grains to the wire. The abrasive grains can include superabrasive materials, such as diamond and cubic boron nitride. Accordingly, the novel wire saw is suitable for cutting ultra thin wafers ceramic wafers with minimum waste of the work piece.

Title: Method for improving the bonding property between the gold (Au) connection wire and the copper (Cu) bonding-pad
Inventor: JANG SHIUN-MING
IPC: H01L21/60
Filed: 1999-08-30
Granted: 2001-02-01
Abstract: Because the resistance of copper is relatively low, it is widely used in the ultra large integrated circuit of the sub-quarter micrometer. However, it is well known that copper is easily eroded in the air. In addition, the reaction property between the Au bonding ball and the Cu bonding pad is very poor. An inert layer of dense aluminum oxide with about 3 to 4 mini-micrometer thickness is formed for aluminum (Al) in air and is used to protect the Al layer below the aluminum oxide from being further oxidized. The reaction property between Au and Al is very good. One of the main purposes of this invention is to add a layer of Al or AlCu alloy to the Cu bonding pad in order to enhance the bonding property between the Cu bonding pad and the Au bonding wire. With this method, the Al or AlCu used as the bonding and protection layer is formed on the Cu bonding pad so as to make the Au bonding wire effectively bond with the Cu bonding pad.

Title: Gas turbine fuel oil, method for producing same and method for power generation
Inventor: OKADA TSUYOSHI
IPC: C10G65/04
Filed: 1999-10-28
Granted: 2001-12-11
Abstract: Feed oil is subject to atmospheric distillation, to thereby be separated into light oil or light distillate and atmospheric residue oil. The light distillate is catalytically contacted with pressurized hydrogen in the presence of a catalyst, resulting in a first hydrotreating step being executed. In this instance, various fractions of the light distillate produced in the atmospheric distillation are subject to hydrotreating in a lump. The atmospheric residue oil is then separated into a light matter and a heavy matter. The light matter is subject to second hydrotreating in the presence of a catalyst to produce refined oil (light matter), which is mixed with refined oil produced in the first hydrotreating to prepare a mixture. The mixture is used as gas turbine fuel oil.

Title: Method and system for protecting sensitive data during automatic testing of hardware
Inventor: ORLIDGE LESLIE ARTHUR
IPC: G01R31/00
Filed: 1999-12-01
Granted: 2003-05-21
Abstract: A system for testing a hardware unit (16) containing sensitive information, while inhibiting access to that information, includes a secure program in an Automated Test Station (10) and an interface circuit (14). The test station has a programmed processor (10a), as well as generating equipment which generates pseudo test signals and measuring devices which measure the response of the unit to actual test signals (10b). Within the processor of the test station there is a test program which does not indicate the sensitive information and a run-time program that interprets the test-program to generate encoded commands for carrying out the test. The interface circuit (14) receives the encoded commands and the pseudo test signals from the test station, decodes the encoded commands and generates the actual test signals. These actual test signals are routed to the unit under test (16) by the interface circuit. The interface circuit also receives the response from the unit to the test signals, encodes it and sends it to the test station for interpretation. The secure run-time program, the encoding by the test station, as well as the encoding and decoding by the interface circuit greatly inhibit the opportunity to uncover the sensitive information during testing of the unit.

Title: Fairness scheme for a serial interface
Inventor: ROSS KEVIN
IPC: H04L12/413
Filed: 2000-05-30
Granted: 2002-08-11
Abstract: To maximize the throughput and minimize the latency associated with communications among devices on a single channel communications system, this invention provides a method and apparatus for a fairness based protocol that assures each device an equal opportunity to access the single channel communications system. The protocol forces a ""fairness"" delay between each sequential transmission from a device, thereby allowing another device to gain access to the communications channel during this fairness delay period. In a preferred embodiment, the duration of each transmission is limited, thereby providing a maximum latency period for a device to gain access to the communications channel, and a minimum bandwidth allocation to the device. By providing a protocol having a guaranteed minimum bandwidth and maximum latency, a device in accordance with this invention need only contain the storage resources needed for the latency period.
