Title: Measurement method of transmission characteristics for acoustic and electrical/electronic transmission line
Inventor: HINO SHIYOUKICHIROU
IPC: H04B17/00
Filed: 2001-06-12
Abstract: PROBLEM TO BE SOLVED: To solve the conventional problem of the need for synchronization between a measuring signal source and the sound-receiving side for receiving a signal outputted from the signal source and transmitted through a transmission system. SOLUTION: When the signal-to-noise ratio is improved by averaging repeated periods of signals in the measurement of waveform information (transmission characteristics) for the signals passed through a system to be measured, the time deviation for each period of signals is corrected from the waveform information of each period obtained from received waveforms. The time deviation quantity is determined by estimating the true maximum value of correlation value by interpolation in the determination of the correlation between a period taken as a reference and the other period.  In the correction of time deviation, each period is converted into information for the amplitude and the phase in the frequency region subjecting to discrete Fourier transformation(DFT), the quantity corresponding to the time deviation is then corrected as phase information, and the sum of each period is averaged as a vector quantity to ensure accuracy of time.

Title: Control device for internal combustion engine
Inventor: ISOBE TAIJI
IPC: F02D29/00
Filed: 2001-06-19
Abstract: PROBLEM TO BE SOLVED: To precisely correct relation between an output value of an oxygen concentration detector to detect oxygen concentration in exhaust gas of an internal combustion engine and the oxygen concentration. SOLUTION: When fuel is cut as engine rotation speed is higher than a learning permitting determination value, an EGR valve and a throttle valve are controlled to be totally opened, so that conditions in an exhaust pipe are forcedly set to be close to atmospheric air conditions (oxygen concentration in atmospheric air, and atmospheric pressure). At a prescribed delay time after start of fuel cut, learning atmospheric air is started, and a reference output value is computed based on output characteristics of an oxygen concentration detector for reference (a standard oxygen concentration detector without having manufacturing dispersion or aging deterioration). This reference output value is corrected in accordance with pressure loss of an exhaust emission control means and atmospheric pressure to determine a final reference output value.  This final reference output value is compared with an actual output value of the oxygen concentration detector, thereby a correction coefficient for correcting the actual output value of the oxygen concentration detector into a real output value without including error due to manufacturing dispersion or aging deterioration is learned.

When the upper end portion of the combustion wicking 4 is ignited to start combustion once, the heat of combustion is conducted through the heat conductor 3 and moved from the upper end portion 3a of the heat conductor 3 projecting into the flame toward the lower end portion 3b. Then, the liquid fuel 1 and the combustion wicking 4 are heated.  The liquid fuel 1 is vaporized by being heated by the heat conductor 3, and generates the vapors burning in the upper side of the mouth part 2a of the container 2. These vapors mix with air to burn with flames (a spontaneous combustion period). Consecutively, the flammable vapors that are vaporized and generated in the container 2 are ejected from a gap 5, and these ejected vapors are ignited to become intense flames (a flame- generating period). This flame-generating period and spontaneous combustion period are repeated several times, so as to enhance the taste and producing effects.
