Assignee:

UNEX Corporation - Chelmsford MA

International Classification:

H04R 2500

US Classification:

381169

Abstract:

A microphone holder includes, a housing comprising a base portion having a first aperture therein and sidewall portions disposed on the base to provide the housing with a microphone receiving cavity region. A cover, having a second aperture therein, is disposed over the cavity region of the housing and a baffle is disposed a predetermined distance over a first surface of the cover in the region of the second aperture.

Filed:

Mar 15, 1991

Appl. No.:

7/670531

Inventors:

James T. MacDonald - Pepperell MA

Assignee:

Unex Corporation - Chelmsford MA

International Classification:

H04R 2500

US Classification:

381187

Abstract:

An adjustable headset headband including a resilient band of a shape and size to fit over the head of a wearer. The band has a first end and a second end and a positioning member fixedly attached adjacent the first end. The headband also includes a housing having a first end and a second end. The positioning member is movably mounted within the housing such that the second end of the housing is oriented nearest the second end of the band. The housing includes a plurality of depressions linearly arranged within the housing from the first end of the housing to the second end of the housing, each depression of the plurality of depressions having a shallower depth than the preceeding depression. The positioning member releasably engages one of the plurality of depressions so as to maintain the positioning member at a predetermined portion within the housing.

US Patent:

54753228, Dec 12, 1995

Filed:

Oct 12, 1993

Appl. No.:

8/135113

Inventors:

James B. MacDonald - Dracut MA

Assignee:

Wang Laboratories, Inc. - Billerica MA

International Classification:

H03K 3017

US Classification:

326 93

Abstract:

A circuit (10) for generating an output signal having a frequency that is a multiple of an input clock signal (CLKIN). The circuit includes a delay circuit (12) having an input port and a plurality of output ports (A,B,C). The input port is coupled during use to the input clock signal. Individual ones of the plurality of output ports output a signal that is delayed with respect to the input clock signal and also with respect to others of the plurality of output ports. The circuit further includes a logic network (20) having a first input for coupling to the input clock signal and a plurality of second inputs for coupling to the plurality of output ports. The logic network operates to logically combine signals emanating from the plurality of output ports with the input clock signal, and has an output port (OUTPUT) for outputting a signal having a frequency that is multiple of a frequency of the input clock signal. The signal that is output from the output port of the logic network has a 50% duty cycle regardless of the duty cycle of the input clock signal.

US Patent:

54532337, Sep 26, 1995

Filed:

Apr 5, 1993

Appl. No.:

8/042942

Inventors:

Alexander Teverovsky - Concord MA
James C. MacDonald - Stoneham MA

Assignee:

CVD, Inc. - Boston MA

International Classification:

C23C 1600

US Classification:

264 81

Abstract:

A method and device are provided for reducing the loss of CVD manufactured parts due to cracking caused by mechanical stresses resulting from the mismatch of the coefficient of thermal expansion between the chemical vapor deposed part and the mandrel plate. The method and device provide a removable mandrel support which is removed after the chemical vapor deposition but prior to the cooling of the CVD part and the mandrel plates. This permits the CVD part to contract upon cooling without mechanical restriction, thus reduce cracking caused by contraction of the CVD part against a mold which does not contract substantially.

International Classification:

C23C 1600

US Classification:

118719

Abstract:

A process and apparatus for the manufacture of chemical vapor deposition deposited structures which comprises supplying a solid zinc metal continuously to a heated retort at a controlled rate. The retort is a body of refractory material having a top and a bottom and a traverse cross section which decreases from the top to the bottom of the retort. The zinc is melted, vaporized, and conveyed to a chemical vapor deposition zone defined by a number of heated mandrel plates where it is reacted with either hydrogen sulfide or hydrogen selenide to form a chemical vapor deposited structure. The process and apparatus provide for improved control over the evaporation rate of zinc and a reduction in the furnace volume needed to melt and vaporize the zinc.
