Assignee:

Hughes Electronics Corp. - Los Angeles CA

International Classification:

H01L 2148

US Classification:

438126, 438127, 295272, 29841, 29855

Abstract:

A chip-on-board electronic device includes an electronic device die affixed to a printed circuit board, and electrically interconnected thereto by wirebonds. The electronic device is protected by coating it with a layer of silicon oxynitride and, optionally, an overlying thin layer of a conformal coating such as parylene. Under some circumstances, a protective layer of an organic material may be used instead of the layer of silicon oxynitride. The chip-on-board electronic device may be protected with an overlying layer of the conformal coating.

International Classification:

B60K 4124

US Classification:

192 18R

Abstract:

A clutch/brake assembly for coupling and decoupling (and simultaneously braking the rotation of) a rotary implement to a drive shaft. The clutch portion of the assembly operates in one mode during low rotational speeds of the implement and at higher rotational speeds changes modes to become a centrifugal clutch. The clutch is also torque sensitive such that when the implement is subjected to high loads and low rotational speeds, the clutch is more tightly engaged to avoid clutch slippage. The brake portion of the assembly has some components common to the clutch assembly. The brake portion is self-energized and constructed to obtain braking assistance from centrifugal force such as at high rotational speeds of the implement and is torque sensitive so that at low rotational speeds and high braking force, the braking surfaces are maintained in tight engagement.

Appl. No.:

6/178398

Inventors:

Ching P. Lo - Culver City CA

International Classification:

F01N 710

US Classification:

60313

Abstract:

An exhaust system for a motorcycle having at least two exhaust conduits connected to different cylinders of a multiple cylinder motorcycle engine. Each exhaust conduit includes a curved flow divider for directing a portion of the exhaust gases through a crossover pipe for passage through the other exhaust conduit.
