Filed:

Mar 16, 1981

Appl. No.:

6/244196

Inventors:

Robert W. Keyes - Ossining NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H03H 942
H03H 964

US Classification:

333155

Abstract:

Surface acoustic wave devices with selectable performance parameters such as having a temperature coefficient of zero, may be fabricated employing a monocrystalline semiconductor substrate with a combination of appropriate doping and crystallographic orientation both with respect to the surface and the direction of propagation. Monocrystalline silicon doped with phosphorous to the order of 2. times. 10. sup. 19 atoms per cc, exhibits a zero temperature coefficient at 300. degree. Kelvin for acoustic waves propagating in the [110] crystallographic direction on a [110] substrate.

Robert Michael Keyes - Bedford Hills NY, US

International Classification:

D06F 1/00

B65D 8/00

Abstract:

A shoelace-cleaning device comprises a spherical housing having first and second halves. Each half has a plurality of apertures allowing for the ingress and egress of fluids. A plurality of tabs are positioned within the interior having a height extending towards the center of the sphere. The spherical housing is dimensioned to receive a plurality of shoelaces once the first half and second half are releasably engaged. Fasteners releasably engage fastener receivers to retain the two halves. The device may then be disposed in a washing machine or drying machine to clean the shoelaces retained within.
