Patent JP-S57180209-A (JP)
Title: Fm signal demodulation system
Inventor: OOTA TOMOZOU
IPC: H03D3/00
Filed: 1981-04-28
Abstract: PURPOSE:To improve the SN ratio of a demodulation signal, by controlling the band width continuously or in step for a variable band pass filter changing the passing band width of the signal. CONSTITUTION:A part of a carrier Ci of an input signal from an input terminal 6 is detected at a signal level detector 1 and an output corresponding to the amplitude of the signal level is obtained. Other parts of the carrier Ci enters a variable band pass filter 2 through an amplifier 5. In this filter 2, as the signal level is smaller around the threshold value through the output of the signal level detector 1, the pass band width is narrower continuously or stepwise. Thus, the noise band width of a signal entering to a discriminator 3 is decided. Then, the carrier power versus noise power ratio C/N of the input signal giving to the discriminator 3 is improved and the SN ratio of the demodulation signal is improved.

Title: Fuel injection control device for internal combustion engine
Inventor: MAKI HIDETAKA
IPC: F02D41/14
Filed: 1996-02-26
Abstract: PURPOSE: To improve stability of control of fuel injection or an air-fuel ratio by properly setting the internal variable of an adaptive controller when rush from an open loop control to a feedback control area is effected. CONSTITUTION: During operation of an engine, a control unit 34 retrieves a map based on the number of revolutions of an engine and an intake pressure to calculate a fundamental fuel injection amount, and in a feedback control region, a feedback correction factor is computed based on the output of an LFA sensor 54. In this case, in an adaptive controller having an adaptive parameter regulating mechanism, an adaptive correction factor is calculated by using a gradualness type so that a detecting air-fuel ratio coincides with a target air-fuel ratio, and the calculating result forms a feedback correction factor. Besides, in a non-feed back control region, an adaptive correction factor is set to 1.0.  Further, when it is not in a preceding feedback control region, the internal variable, containing a past value, of an adaptive control rule is set to 1 or a value approximately equal to 1 and used for computation of a fuel injection amount.

Title: Low noise pantograph
Inventor: SEHATA MICHIO
IPC: B60L5/24
Filed: 1990-03-16
Abstract: PURPOSE:To suppress aerodynamic noise level by arranging a collector shoe and a ceiling pipe, which are perpendicular to the flow line of traveling wind, with a predetermined acute angle. CONSTITUTION:When a collector shoe 1a and a ceiling pipe 5a are arranged with an acute angle theta1-75 deg., 60 deg. or 45 deg. with respect to the flow line (mu) of traveling wind, noise level is decreased considerably if theta1 is less than 45 deg.. When the collector shoe 1a and the ceiling pipe 5a are arranged with an acute angle theta1, production of Karman vortex in the downsteam of the collector shoe 1a and the ceiling pipe 5a, which is determined by the cross sectional shape, magnitude and the speed, is suppressed under high speed traveling. Since only one acute angle is set, structures of the collector shoe 1a and the ceiling pipe 5a are not complicated. When the acute angle is increased, the lengths of the collector shoe 1a and the ceiling pipe 5a are shortened and the rigidity is increased in the longitudinal direction. Consequently, aerodynamic noise of a pantograph can be suppressed.
