US Patent:

51664925, Nov 24, 1992

Filed:

Mar 27, 1991

Appl. No.:

7/676021

Inventors:

Ruben Rivera - Davie FL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B23K 2600

US Classification:

21912168

Abstract:

Briefly, according to the invention, a laser trim system (100) for trimming printed components (112) on a circuit carrying substrate (118) is disclosed. The laser trim system (100) includes a laser source (102) for trimming the printed circuit components (112). The laser source (102) has an adjustable power level, suitable for trimming a variety of printed components. The laser trim system (100) also includes a power converter (110) for selectively measuring the power level of the laser source (102). A laser power supply (104) is also included in the laser trim system (100) for adjusting the power level of the laser source (102) in response to the measured power level. The laser trim system (100) further includes a computer (1068) for comparing the measured laser power level with pre-defined levels to determine when a change in the power level is necessary.

International Classification:

H05K 900

US Classification:

174 35GC

Abstract:

A shielding enclosure (10) shields an electronic circuit (12) from radio frequency interference (RFI) or electromagnetic interferences (EMI). The shielding enclosure is an electrically conductive polyhedron having at least one aperture (18). The enclosure has a closable member (20), which is a part of the polyhedron, arranged to enable the aperture to be opened and closed. The polyhedron can be an electrically conductive metal enclosure that covers the shielded circuit, and is mechanically and electrically attached to the circuit. The aperture has an integral flap (21) connected to the enclosure at one end (23), so that it is able to be opened and closed to reveal the shielded circuit. Any openings remaining in the polyhedron when the aperture is closed are less than or equal to 1/4 wavelength of the interfering radio frequency energy.

International Classification:

H02K 5/173
F16C 35/067

Abstract:

An integrated magnetic shield and bearing holder useable with electric motors includes a shaft portion and a cover portion extending radially outward from the shaft portion. The shaft portion includes an inner wall defining a channel and a ledge extending radially inward from the inner wall. The cover portion includes a first layer, a second layer extending substantially parallel to the first layer, a magnetic shield extending between the first layer and the second layer, and an outer wall extending from the first layer and/or the second layer such that a space is defined between the outer wall and the shaft portion. The cover portion includes one or more retainers coupled to the magnetic shield to restrict movement of the magnetic shield relative to the first layer and/or the second layer.
