20090104416, Apr 23, 2009

Filed:

Oct 19, 2007

Appl. No.:

11/875379

Inventors:

Jung Soon Chang - Glendale CA, US

International Classification:

B44F 3/00

US Classification:

428196

Abstract:

A decorative fabric for automotive use includes a fabric piece that is attached to a predetermined location of an automobile and a plurality of discrete decorative pieces that are attached to predetermined positions, which forms a desired pattern, on the fabric piece. Each of the decorative pieces comprises a hard outer piece that has a predetermined shape, and a heat-curing adhesive layer that fixes the hard outer piece to the fabric piece. The hard outer piece includes a metal stud and an artificial gem stone.

Appl. No.:

7/561630

Inventors:

Hu H. Chao - Pleasantville NY
Jung H. Chang - Saratoga CA

Assignee:

IBM Corporation - Armonk NY

International Classification:

G06F 1100

US Classification:

371 101

Abstract:

An apparatus for correcting a faulty microcode contained in a control store of a microprogrammed processor. The apparatus comprises two functional parts; namely, the detection circuit for detecting operational codes that correspond to faulty microinstructions in the main control store ROM of the system and a programmable array which is used as the storage area for substitute microinstructions. The detection circuit is a circuit which operates as a logic NOR circuit and is utilized to detect valid operational codes of macroinstructions that correspond to microcode sequences that contain errors or faults. The programmable array consists of two loadable RAM's which contain error free microcode to replace the faulty microcode. The detection and correction occurs in parallel with the instruction decoding so that it does not have any impact on system cycle time.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 104
G06F 13372
H03K 17687

US Classification:

395550

Abstract:

A circuit to provide single phase clock signals having controlled clock skew to multiple integrated circuit chips is described. A source of single phase clock signals is supplied to a clock signal distribution tree of each integrated circuit. Phase comparison of signals produced by each clock distribution circuit tree provides a control signal for controlling the delay of a clock signal applied to a respective clock distribution tree. A gating circuit is disclosed which produces, in response to each clock signal produced by the clock distribution trees, an accurately controlled LOAD ENABLE and OUTPUT ENABLE signal.
