Title: Virtual channel support in a nonvolatile memory controller
Inventor: KUEHNE REINHARD
IPC: G06F12/08
Filed: 2011-02-23
Abstract: A controller uses N dedicated ports to receive N signals from N non-volatile memories independent of each other, and uses a bus in a time shared manner to transfer data to and from the N non-volatile memories. The controller receives from a processor, multiple operations to perform data transfers, and stores the operations along with a valid bit set active by the processor. When a signal from a non-volatile memory is active indicating its readiness and when a corresponding operation has a valid bit active, the controller starts performance of the operation. When the readiness signal becomes inactive, the controller internally suspends the operation and starts performing another operation on another non-volatile memory whose readiness signal is active and for which an operation is valid. A suspended operation may be resumed any time after the corresponding readiness signal becomes active and on operation completion the valid bit is set inactive.

Title: Inspection method and inspection apparatus for circuit substrate
Inventor: TSUCHIDA KENGO
IPC: G01R31/28
Filed: 2011-03-03
Abstract: In an electrical inspection method/apparatus for performing an electrical inspection in which an inspection probe having a probe needle at a distal end moves toward a circuit substrate having a plurality of terminals, a plurality of representative terminals surrounding an inspected terminal is selected, so that the inspection probe moves toward each of the representative terminals so as to detect a position, at which electrical conduction with the probe needle is detected, as a contact position of the inspection probe. Interpolation is performed on the contact position of the inspection probe with respect to each of the representative terminals; a depression value necessary for a further movement of the inspection probe from the contact position to the inspected terminal is added, so that a target move position of the inspection probe is calculated. The inspection probe moves toward the target move position so as to perform an electrical inspection on the inspected terminal. Thus, regardless of dispersions of thickness and warp/waviness occurring on a circuit substrate, it is possible to perform an electrical inspection in which the inspection probe precisely comes in contact with the inspected terminal as it is adapted to non-linear displacements occurring on the surface of a circuit substrate.

Title: Method of producing fuel oil from active sludge via bundle type cracking furnace
Inventor: CHOU YING-JEN
IPC: C10G9/20
Filed: 2011-05-13
Abstract: This invention relates to a method of producing fuel oil from active sludge via a bundle type cracking furnace, wherein the main steps can be divided into the following three portions, comprising a slurry preparation step, a concentration step and a pyrolysis, gasification and oilation step. Since inorganic ash containing less than or equal to 5% of organics is isolated in advance, the oil production yield is increased to 60% to 65% of the organics, and the fuel gas production yield is up to 30% to 35% of the organics, with the condensate having fatty acid less than about 2%. This invention overcomes the disadvantages of a conventional cracking furnace. Given the identical per unit furnace volume, the oil gas production yield of this invention increases 3 to 4 times higher than a conventional cracking furnace, while the manufacturing costs is only 1.3 times of the conventional cracking furnace.
