Appl. No.:

11/756899

Inventors:

Michael W Matthews - Chicago IL, US
Sunil B. Phatak - Bensenville IL, US

Assignee:

Rubicon Technology, Inc. - Bensenville IL

International Classification:

B32B 3/02
H01L 23/544
H01L 29/30

US Classification:

428 667, 148 332, 257797, 428 641

Abstract:

The present invention consists of a method for imparting asymmetry to a truncated annular wafer by either rounding one corner of the orientation flat, or rounding one corner of a notch. This novel method of rounding corners impart a visual and/or tactile asymmetry which can be utilized by a person in order to differentiate between the two different sides of the wafer. This inventive wafer design and method for making an asymmetric wafer is especially useful in the field of semiconductor technology and may be used on sapphire crystal wafers or any other class of wafer.

US Classification:

12602100A

Abstract:

A self-cleaning, gas-fired tunnel oven is provided. One embodiment of the oven provides a self-cleaning, gas-fired tunnel oven for cooking food products. The oven includes a control system that regulates oven temperature during a pyrolitic, self-cleaning procedure for incinerating contaminants that accumulate inside; a burner for cooking food products and incinerating contaminants; a modulating air and fuel control system arranged for proportionally delivering air and fuel to the burner; a plurality of convection air fingers for directing heated air toward the food products; a collapsible conveyor, capable of fitting into the oven when collapsed, for passing the food products through the oven; a plurality of blowers, each having a dedicated speed controller; a floating cooking chamber; and a vent system that maintains a negative pressure in the oven during the self-cleaning procedure

15/253604

Inventors:

Michael Matthews - Washington DC, US
Gregory Harvin - Washington DC, US

International Classification:

B26B 19/38

Abstract:

A hair razor with interactive features including RPM control protocol that includes: an under side; an interactive display placed on the under side, where the interactive display provides access to display applications stored in memory; a top side; a digital display on the top side, where the digital display provides operational information related to the hair razor; a motor; a motherboard, where the motherboard is adapted to provide RPM control for the motor, wherein said RPM control is accomplished by syncing RPM speeds with musical notes; a USB connector on one side of the hair razor; a touch control button on the top side of the hair razor; and a power cord, the power cord supplies power to the hair razor. The interactive display is adapted to maneuver through a plurality of screen selections. The operational information shown on the digital display includes pitch tone associated with the RPM speed of the motor.

Appl. No.:

14/298502

Inventors:

Michael Matthews - Washington DC, US
Gregory Harvin - Washington DC, US

International Classification:

B26B 19/38

Abstract:

An electric clipper having a visual feedback system for displaying the running RPMs thereof. The electric clipper having a visual feedback system comprises a base hair clipper which includes an external display screen. The base hair clipper is constructed as conventional electric hair clippers and includes tuner is connected to the base hair clipper's internal motor and enables the operating speed of the motor to be adjusted. An internal tachometer is additionally included in the base hair clipper to generate measurements of the rotation speed of the motor. Such measurements are displayed on the external display, defined as an LED display. The LED display is configured to provide a digital readout of the RPMs of the motor in real time and provide a color coded output corresponding to a general range of RPMs.
