Abstract: There is employed a configuration such that a dry distillation   gas   generator   for   generating   a   dry distillation  gas  and  a  combustion gas  burner unit  for completely  burning  a  gasified  fuel  are  completely partitioned  or  divided,   thus  attempting  to  improve respective functions as far as possible.   The section of the air supply means of the dry distillation gas generator is improved, and an impurity separation tank is provided in the middle portion connecting the dry distillation gas generator and the combustion gas burner unit to improve cleanness of the distillation gas.   The combustion gas burner unit  carries  out  combustion  while  sufficiently agitating and mixing an air blown off and supplied from the openings of the first and second air supply sections within a cylindrical burner body heated in advance,  thus attempting to realize a complete combustion of a higher level.     A  dry  distillation  gasification  combustion equipment  is  characterized  in  that  a  gas  conduit  is connected  to a dry distillation  gas  outlet of the dry distillation gas generator,  that an impurity separation tank is provided in the middle of the gas conduit, and that the combustion gas burner unit is connected or joined to the front end portion of the gas conduit.   In the dry distillation  gas generator,  an  air chamber and an air blowoff  section communicating with  the air chamber are disposed on the bottom portion of the tank furnace.   An air supplied is caused to softly and evenly spread over the entirety of  the bottom surface along the air vent recessed  portion  around  the  air  dispersion  cap.    The combustion gas burner unit is such that a preheat burner section,  and first  and  second air supply sections  are provided in the cylindrical burner body.   Thus,  an air blown off and supplied from the opening of the first air supply section  is agitated and mixed with a combustion gas.  Further, an air pre-heated at the air storage layer is  supplied  from  the  second  air  supply  section,  thus making it possible to agitate and mix the air with the combustion gas in the vicinity of the combustion opening portion.   The  dry distillation  gasification  combustion equipment thus featured is provided.

Title: A device and process for generating and measuring the shape of an acoustic reflectance curve of an ear
Inventor: COMBS JEROME T
IPC: A61B5/12
Filed: 1996-01-26
Granted: 1999-11-23
Abstract: A device or a process for analysis of acoustic reflectance of components of an ear involves directing, into the ear canal, acoustic waves covering a range of frequencies including resonance frequencies of ear components such as the tympanic membrane. Measurements are made without pressurizing the ear canal and contact between the device and the ear does not need to be air-tight. Accordingly, the patient experiences essentially no discomfort from use of the device. The device detects and combines the incident and reflected waves to produce what is called an acoustic reflectance curve. The shape of a region of the acoustic reflectance curve is electronically measured in order to obtain an indicator of ear condition which is substantially independent of a line of sight between a sound source and the tympanic membrane. This indicator is based on a mesurement of the resonance characteristic, or freedom of motion, of the tympanic membrane or other ear component being analyzed. One such measurement is the rate of change of the acoustic reflectance with respect to frequency. Since resonance typically causes a null to appear in the acoustic reflectance curve, this measurement of the rate of change is particularly informative if measured around the null. The rate of change measured around the null may be presented as an angle measurement, a gradient or slope measurement, a width measurement, or other form of measurement of the shape of the null. In one embodiment, the steepest slopes on either side of a null are used to define an angle, herein called a spectral gradient. Diagnosis of an ear pathology, such as abnormal pressure or presence of fluid in the middle ear or such as conductive hearing loss, may be based on this measure alone. Because of the rate of change of an acoustic reflectance measurement is relatively constant for a given ear, regardless of the quality of the line of sight to the tympanic membrane, the effect, if any, of user training on such measurements is significantly reduced. Accordingly, the process and device of the invention are useful in many kinds of diagnostic situations with respect to ear pathology, but particularly in those involving screening of the ears of young children for common pathologies such as otitis media, even by untrained personnel.

Abstract: A pressing section of a papermaking machine is configured to increase pressed dryness significantly while maintaining substantial "one-sidedness", where both sides of the paper sheet have essentially identical surface characteristics. To strike a commercially useful balance between the application of high temperatures and pressures which increase paper dryness but can result in the production of two-sided paper and lowering nip pressure, which enhances one-sidedness but lowers effectiveness in removing water from the paper web, a press section according to the present invention has two conventional presses followed by two or three presses including one heated Extended Nip press. Preferably, smooth high temperature press felts are used to assist in the reduction of two-sidedness of the formed web. The dryer section may, alternatively, add a fifth press utilizing the first dry roll as the backing roll, two Extended Nip presses, a heated Extended Nip press followed by a heated conventional press, or a heated Extended Nip press in the third pressing section, followed by a conventional unheated press utilizing the first dryer as the backing roll.

Title: Noise cancelling method and apparatus for the same
Inventor: IKEDA SHIGEJI
IPC: H04B1/10
Filed: 1998-01-28
Granted: 2001-12-18
Abstract: A noise canceler of the present invention is of the type including an adaptive filter for generating a pseudo noise signal, subtracting the pseudo noise signal from a received signal to thereby output an error signal, and sequentially correcting the filter coefficient of the filter in accordance with the error signal. A second adaptive filter produces a second pseudo noise signal and a second error signal. A first and a second power mean circuit each calculates the signal power of the respective signal. A divider performs division with the resulting two kinds of signal power, so that a signal-to-noisepower ratio is estimated. A comparator compares the estimated signal-to-noise power ratio and a delayed version of the same and outputs greater one of them as an extended signal-to-noise power ratio. A step size output circuit corrects,based on the extended signal-to-noise power ratio and reference noise signal power output from a power mean circuit, a step size used to adaptively vary the filter coefficient of the first adaptive filter.

Abstract: In a combined cycle power plant, exhaust from a high pressure turbine is branched so that part of it is supplied to a steam cooling system, and the other part of it is supplied to an inlet of a reheater of an exhaust heat recovery boiler. The exhaust supplied to the steam cooling system performs predetermined cooling and becomes heated. Then, the heated exhaust is guided from an outlet of the steam cooling system to an intermediate position of the reheater, merged with the exhaust supplied to the inlet of the reheater, and temperature-adjusted in the reheater. Then, the reheated, combined steam is supplied to a downstream turbine for heat recovery. Thus, a safe, reliable steam cooling system is achieved by effectively using a sufficient amount of high pressure turbine exhaust.
