  • Patent number: 7022937
    Abstract: A plasma processing method is used to process a linear portion of an object to be processed by generating a linear plasma by supplying an electric power to an electrode provided at a plasma source or the object to be processed while supplying gas to the plasma source arranged in the neighborhood of the object to be processed and making activated particles generated by the plasma act on the object to be processed. The method includes detecting an inclination of the plasma source along a direction of an x-axis when the x-axis is taken in a linear direction of the linear portion of the object to be processed, and processing the linear portion of the object to be processed by the generated linear plasma by moving the plasma source along the x-axis direction while maintaining relative positions of the plasma source and the object to be processed so that the detected inclination of the plasma source becomes approximately zero.

  • Patent number: 7015441
    Abstract: An apparatus and method for heating a sample, such as chemical reaction mixtures are disclosed. The apparatus may include at least a microwave generator, a waveguide for guiding the generated microwaves to an applicator, and a deflector formed by a closed loop defining a plane. The deflector may have an inherent resonance frequency and a thickness in a direction normal to the plane. The deflector may be rotatable around an axis being at least substantially parallel to the plane, and positioned in the waveguide so as to form a resonant cavity with the sample and the waveguide applicator. The resonance conditions of the resonant cavity and the coupling factor of radiation from the waveguide to the cavity may be easily adjustable by rotating the deflector. The resonance conditions and the coupling factor may be adjusted in response to the dielectric properties of the sample in order to optimize the amount of absorbed power and thereby obtain control of the sample heating process.

  • Patent number: 7009487
    Abstract: The method for the fabrication of nano scale temperature sensors and nano scale heaters using focused ion beam (FIB) techniques. The process used to deposit metal nano strips to form a sensor is ion beam assisted chemical vapor deposition (CVD). The FIB Ga+ ion beam can be used to decompose W(CO)6 molecules to deposit a tungsten nano-strip on a suitable substrate. The same substrate can also be used for Pt nano-strip deposition. The precursors for the Pt can be trimethyl platinum (CH3)3Pt in the present case. Because of the Ga+ beam used in the deposition, both Pt and W nano-strips can contain a certain percentage of Ga impurities, which we denoted as Pt(Ga) and W(Ga) respectively. Our characterization of the response of this Pt(Ga)/W(Ga) nano scale junction indicates it has a temperature coefficient of approximately 5.4 mV/° C. This is a factor of approximately 130 larger than the conventional K-type thermocouples.

  • Patent number: 7009153
    Abstract: A heat roller with which a pressure roller is brought into press contact is rotatably supported by a bearing member made of a material which is softened when heated above a thermal fixation temperature, a thermostat in which a bimetal is exposed toward the heat roller is disposed at the opposite side of the heat roller with respect to the pressure roller, and a heat conduction member is made to intervene between the heat roller and the bimetal. According to the above configuration, the power supply to a fixation heater can be cut off by the thermal deformation of the bimetal. The heat roller is moved by softening of the bearing member, and the bimetal is mechanically deformed by pressing of the heat conduction member. Therefore, the power supply to the fixation heater can be cut off.

  • Patent number: 7005620
    Abstract: A piston particularly adapted for heavy-duty diesel engine applications is fabricated from separate parts having circumferentially extending joining surfaces that are heated prior to bonding to an elevated temperature sufficient to enable bonding of the joining surfaces, and thereafter the joining surfaces brought into contact with one another and twisted to attain a permanent metallurgical weld at the interface of the joining surfaces. The piston has radially spaced walls which are both welded simultaneously. The weld joints may lie in the same or different planes. Once joined, and while still hot, the parts may be pulled apart slightly to reduce the wall thicknesses at the weld joint.
