Publication number: 20070012049Abstract: The present invention mainly utilizes a specialized semiconductor ship, the so-called thermoelectric cooling chip, for producing the coldness. A cooling circulating member and a heat dissipating member are configured at the two sides of the thermoelectric cooling chip. The coldness produced by the thermoelectric cooling chip is delivered by a cold conduction plate and cooling pipes, and is stored in fins of the cooling circulating member. A temperature controller determines a desired temperature and the coldness stored in the fins are blown out as cool air by a fan. Similarly, the heat produced by the chip is dissipated by the heat dissipating member. As such, the present invention could reach the desired temperature within a short period of time without the conventional compressor. The present invention therefore is easier to install and transport, consumes less power, and produces almost no noise and pollution to the environment.Type: ApplicationFiled: October 14, 2005Publication date: January 18, 2007Inventor: Chuan-Sheng Chen

Publication number: 20070012050Abstract: This invention relates prolonging operation duration of ambient air heated vaporizers of cryogenic fluids; and more particularly concerns a method for enhancing ice removal under such vaporizers. Ambient air vaporizers have been used in the past to convert cryogenic fluids into warm gas. Because of the very cold surfaces inherent in the construction of these vaporizers, they collect frost or ice, and are generally limited in the time they can be effective due to the reduction in heat transfer caused by the frozen atmospheric water collecting on vaporizer surfaces. Operators frequently seek to mitigate this effect by having multiple vaporizers, alternately switching units on and off, allowing them to defrost. A characteristic of these defrosting vaporizers, is the falling of the frost and ice off the heat transfer surfaces, collect at the base of the unit (the “Pile). This Pile of frozen water or slush generally can be melted by exposure to warm ambient air during the defrost cycle.Type: ApplicationFiled: July 18, 2005Publication date: January 18, 2007Inventor: Ross Brown

Publication number: 20070012085Abstract: In a method for detecting abnormal characteristic values of at least three products sequentially manufactured in the same manufacturing line, it is determined whether or not a successively-alternate increase/decrease tendency has occurred in a plurality of sequentially-obtained characteristic values of the products. Also, it is determined whether or not at least one of the characteristic values is located within a control region narrower than an allowable region and outside a normal region narrower than the control region. Further, when the successively-alternate increase/decrease tendency has occurred and the at least one characteristic value is located within the control region outside the normal region, an alarm state is detected.Type: ApplicationFiled: July 12, 2006Publication date: January 18, 2007Applicant: NEC ELECTRONICS CORPORATIONInventor: Masanobu Higashide

Publication number: 20070012086Abstract: An air-fuel ratio sensor monitor is provided which is designed to monitor reactive characteristics or response rates of an air-fuel ratio sensor when an air-fuel ratio of a mixture to an internal combustion engine is changing to a rich side and to a lean side. The monitored response rates are used in determining whether the sensor is failing or not, in determining the air-fuel ratio of the mixture accurately, or in air-fuel ratio control of the engine.Type: ApplicationFiled: September 14, 2006Publication date: January 18, 2007Applicant: Denso CorporationInventors: Noriaki Ikemoto, Naoki Yoshiume, Yukihiro Yamashita

Publication number: 20070012087Abstract: A measurement sensor for determining a physical property of a measurement gas, e.g., the concentration of a gas component or the temperature of a measurement gas, in particular of the exhaust gas of internal combustion engines, has a housing and a sensor element accommodated in the housing. The sensor element has an end segment at the measurement gas side that protrudes from the housing and a connection-side end segment that bears at least one contact surface. The sensor element also has at least one conductor element that contacts the at least one contact surface. In order to achieve low transition resistances at the electrical contacting and a decoupling from mechanical stress, the contact surface and the conductor element are connected to one another by welding, and are embedded in a ceramic compound at least in the area of the welded connection.Type: ApplicationFiled: February 9, 2004Publication date: January 18, 2007Inventors: Juergen Ruth, Andreas Pesch

Publication number: 20070012089Abstract: A sensor for use with a polysomnograph in a sleep lab setting is made reusable by laminating a PVDF film and associated lead contacts within a flexible, moisture-impervious plastic envelope that is hermetically sealed about its periphery. Lead terminals within the envelope are adhered to the metalized surfaces of the PVDP film using a conductive adhesive which inhibits dislodgement of the leads from the sensor even with rough handling and cleaning.Type: ApplicationFiled: July 11, 2006Publication date: January 18, 2007Applicant: Dymedix CorporationInventor: Peter Stasz

Publication number: 20070012090Abstract: An engine ECU includes a bandpass filter (1) extracting only vibrations at a first frequency band A, a bandpass filter (2) extracting only vibrations at a second frequency band B, a bandpass filter (3) extracting only vibrations at a third frequency band C, and a bandpass filter (4) extracting only vibrations at a fourth frequency band D including the first to third frequency bands A-C. The engine ECU determines whether knocking occurred or not based on a vibration waveform of the fourth frequency band D and a peak value in magnitude of vibrations in a synthesized waveform of the first to third frequency bands.Type: ApplicationFiled: June 28, 2006Publication date: January 18, 2007Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Masatomo Yoshihara, Kenji Kasashima, Rihito Kaneko, Koji Aso, Kenji Senda, Yuichi Takemura, Kiyoshi Iwade, Shuhei Oe

Publication number: 20070012092Abstract: In a method for testing the thermally induced unbalance of a rotating machine part, in particular the rotor of a turbogenerator, the rotating machine part or the rotor balanced at normal temperature is brought in the demounted state first to nominal rotational speed and held at this, while its temperature is varied and, at the same time, the transient variations in oscillations of the rotating machine part or rotor which are caused are measured. During the test, the rotating machine part or the rotor is surrounded at least partially by a closed heating cell, a cooling medium flows around and/or flows through the rotating machine part or the rotor in the heating cell, and the heating of the rotating machine part or of the rotor takes place essentially due to the flow-dynamic losses arising from the interaction of the rotating machine part or of the rotor with the circulating cooling medium.Type: ApplicationFiled: April 12, 2006Publication date: January 18, 2007Applicant: ALSTOM Technology LtdInventors: Eric Aubriat, Ludovic Bregy, Andrew Holmes, Georg Klein, Eric Veith, Michel Verrier
