| 20080277389 | IN-LINE MICROWAVE WARMING APPARATUS - Microwave warming apparatus includes a housing defining a heating waveguide with a longitudinal ridge and a heating cavity. A slot extends through the ridge into the heating cavity for receiving a cartridge containing a looped tube so that the tube extends into the heating cavity where the tube contents are heated by energy coupled into the waveguide. Receiving waveguides adjacent to the slot sense the thermal radiation emanating from the tube and deliver corresponding signals to a radiometer which produces a temperature indication. The cartridge includes a support member which maintains the shape of the tube loop. A pair of notches in the support member have walls enabling the notches to complete the receiving waveguides in the housing. | 11-13-2008 |
| 20090321432 | Apparatus for Processing a Wafer - An apparatus for processing a wafer includes a chamber, a boat, microwave generators and reflective plates. The boat is disposed in the chamber. One or more wafers are stacked in the boat. One or more microwave generators are connected to the chamber. The microwave generators generate microwaves for heating the wafers. The reflective plates reflect the microwaves onto the wafers such that the microwaves are uniformly applied to the wafers. Each of the reflective plates faces at least one of both sides of the wafer. The reflective plates include at least one of a fat side, a concave side and a convex side. | 12-31-2009 |
| 20100264136 | MICROWAVE PELLET FURNACE AND METHOD - One aspect is a microwave furnace including a conveyor for conveying a first material layer, and a second material layer carried on the first material layer, through the furnace. A microwave heating zone is configured for heating the second material layer with a microwave generator as the conveyer conveys the layers through the microwave heating zone. The second material layer consists of a metal-containing material. A direct heat zone is configured for heating the second material layer with a direct heat source as the conveyer conveys the layers through the direct heat zone. A discharge is provided for discharging the material layers out of the microwave furnace. | 10-21-2010 |

| 20130015182 | MAGNETRON AND APPARATUS THAT USES MICROWAVESAANM Akutsu; KazuyasuAACI TochigiAACO JPAAGP Akutsu; Kazuyasu Tochigi JPAANM Kuwahara; NagisaAACI ShigaAACO JPAAGP Kuwahara; Nagisa Shiga JP - A magnetron includes: an anode tube; and cooling fins placed on a periphery of the anode tube, and arranged along a central axis of the anode tube. Each of the cooling fins includes at least two sets of fins formed by cutting a part of the cooling fin, and performing different bending works on the cut portions, respectively, so as to form a region where the cooling fins are dense and a region where the cooling fins are sparse, when viewed in a flowing direction of a cooling medium which cools the anode tube through the cooling fins. The at least two sets of fins are bent at bending angles such that intervals of the cooling fins in the region where the cooling fins are dense are ½ or less of placement intervals of the cooling fins. | 01-17-2013 |
| 20130026159 | OSCILLATOR SYSTEMS HAVING ANNULAR RESONANT CIRCUITRY - Systems and apparatus are provided for solid-state oscillators and related resonant circuitry. An exemplary oscillator system includes an amplifier having an amplifier input and an amplifier output and resonant circuitry coupled between the amplifier output and the amplifier input. In exemplary embodiments, the resonant circuitry includes an annular resonance structure that is substantially symmetrical and includes a pair of arcuate inductive elements. In accordance with one or more embodiments, the resonant circuitry includes an additional inductive element that is capacitively coupled to the annular resonance structure via an air gap to improve the quality factor of the resonant circuitry. | 01-31-2013 |
| 20140008357 | MICROWAVE POWER SOURCE AND METHOD OF AUTOMATIC ADJUSTEMENT OF OPERATION FREQUENCE - Disclosed are a microwave power source and a method of adjusting operation frequency for a microwave oven. The microwave power source comprises: a phase-locked frequency generator configured to generate a plurality of operation frequencies; a standing wave detection circuit configured to detect, for each operation frequency, a standing wave in a chamber of the oven and provide information about the standing wave; and a microcontroller configured to select one of the operation frequencies based on the information, and control the generator to generate the selected operation frequency so that the microwave oven operates at the selected operation frequency. Embodiments of the present disclosure can automatically adjust the operation frequency of the oven according to VSWR in the oven chamber. | 01-09-2014 |
