Title: Magnetic recording device
Inventor: SATOU TSUGUO
IPC: G11B20/06
Filed: 1982-11-08
Abstract: PURPOSE:To prevent the incidence of an inversion phenomenon even when a frequency modulated luminance signal changes from a black level frequency to a white level frequency, by recording a signal obtained by amplitude-modulating a frequency modulated signal by means of the output signal of a high-pass filter on a magnetic medium. CONSTITUTION:A luminance signal is supplied to a frequency modulating circuit 3 through a pre-emphasis circut 2 and, at the same time, a luminance signal obtained at the output side of the circuit 2 is supplied to a high-pass filter 6. It is arranged that a frequency modulated luminance signal obtained at the output side of the circuit 3 is supplied to an amplitude modulating circuit 7 and the luminance signal is amplitude-modulated by the output signal of the high- pass filter 6. In this way, the amplitude of a frequency modulated luminance signal corresponding to a part which changes from the black level to the white level can be made larger, namely can be made larger in level. Therefore, incidence of a white-black inversion phenomenon can be prevented because there is no point where the magnetization intensity abruptly changes when a magnetic tape is reproduced.

Title: Inter-vehicle distance control device
Inventor: SATO YASUHIKO
IPC: B60K31/00
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent deviation between a set vehicle speed and a practical vehicle speed in traveling at a constant speed by stopping a vehicle speed feedback control and starting an acceleration feedback control as substitute for it, when a target acceleration becomes a negative acceleration to decelerate an own car. SOLUTION: In controlling an inter-vehicle distance by a computer 11, the presence of a preceding vehicle is judged at first by an inter-vehicle distance sensor 13. When the preceding vehicle is present, after the preceding vehicle or the control reference is specified, the relative speed between the own vehicle and the preceding vehicle is calculated from the time change in the inter-vehicle distance and the inter-vehicle deviation which is a difference between the target inter-vehicle distance corresponding to the practical vehicle speed V of the own vehicle and the practical vehicle distance is calculated so that the target acceleration is calculated based on a map recorded in a ROM using the relative speed and the inter-vehicle deviation.  When the target acceleration becomes a negative acceleration for decelerating the own vehicle, the vehicle speed feedback control is stopped and the acceleration feedback control is started as substitute for it.

Title: Method for estimating area and amount of gas leakage taking obstacle into consideration
Inventor: NISHINO HARUO
IPC: G01M3/04
Filed: 1994-07-27
Abstract: PURPOSE:To estimate the area of gas leakage from gas concentration data and anemometer data by estimating the standard deviation of the gas concentration distribution of a gaseous diffusion equation from the standard deviation of the wind direction variation of an anemovane at every bearing. CONSTITUTION:A data processor 3 calculates gas flux by taking out gas concentration data from a gas concentration data collecting/storing device 1 and wind direction and speed data for each detector from a wind direction and speed collecting/storing device 2 and multiplying the former data by the latter data. For example, gas detectors G1-G10 are arranged around a frame at regular intervals of 20m in a state where the detectors G1-G10 are respectively united with anemovanes B1-B10 and the mean values and standard deviation of the wind directions and speeds corresponding to the detectors G1-G10 are found based on the data from the anemovanes B1-B10. At the time of finding the mean value and standard deviation, established correction is performed so that sigmaY=0.018XsigmaA and sigmaZ=0.054KXsigmaE (where, sigmaY and sigmaZ respectively represent the standard deviations of gas concentration distributions in Y- and Z- directions, sigmaA and sigmaE respectively represent the standard deviations of wind direction variation in the horizontal and vertical directions, and K represents an empirical constant which varies depending upon the stability of atmosphere) can hold.
