A hydraulic control system for an automatic transmission is disclosed which includes a feedback hydraulic control circuit and a hydraulic correcting circuit. The feedback hydraulic control circuit controls the hydraulic pressure supplied to frictional elements of the automatic transmission under feedback control during a shift operation for adjusting the speed of an input shaft or a rate of change in speed of the input shaft of the automatic transmission to agree with a target speed or a target rate. The hydraulic correcting circuit corrects an output of the feedback hydraulic control circuit so as to suppress vibrations of torque transmitted through a drive train of the automatic transmission caused by control of the hydraulic pressure carried out by the feedback hydraulic control circuit within a range of a resonance frequency of the drive train of the automatic transmission.

A fuel injection nozzle is configured and dimensional with a flat flow passage just above the outlet orifice(s). When the abutting portion of a needle valve moves away from the valve seat, fuel flows are directed uniformly toward the orifice from around its periphery so as to collide with each other just above each orifice inlet. Atomized fuel is then injected to the engine from the orifice. The internal energy of the fuel flows can more effectively be utilized in the collisions to more finely atomize the fuel and to maintain the ability to provide a highly direction output injection spray.

An air-to-fuel ratio control apparatus for an internal combustion engine includes an air-to-fuel ratio sensor of a current limiting type for detecting an air-to-fuel ratio of an air-fuel mixture from a condition of exhaust gas originating from the air-fuel mixture. An air-to-fuel ratio controlling device is operative for performing feedback control in response to an output signal of the air-to-fuel ratio sensor so that the detected air-to-fuel ratio will be substantially equal to a target air-to-fuel ratio. A gain setting device is operative for setting a feedback gain of the air-to-fuel ratio feedback control in response to an atmospheric pressure.

A fuel supply system of an internal combustion engine includes, a fuel return branch connection positioned downstream of a fuel filter. The branch connection returns part of the fuel which passed the fuel filter back into the fuel tank. An end of the fuel return connection is extended to the bottom of the fuel tank. A throttle part for controlling returned fuel flow is positioned in the branch connection. Because part of fuel which passed the fuel filter is returned into the fuel tank, fuel in the fuel tank is repeatedly filtered by the fuel filter. Thus, removal of dust in the fuel is improved and total fuel flow passing through the fuel pump is increased. This improves cooling of the fuel pump and thus helps prevent vapor generation while also improving durability of the pump.

A heads-up display unit provided with a display device serving as display image forming means which displays a display image. A hologram serves as a reflecting means, and reflects the display light emitted from the display device, causing reflection of the display image on the interior surface of a vehicle's windshield. A display image is formed outside the windshield towards the front of the vehicle. A concave mirror having a different focal length in different directions is recorded in the hologram serving as a reflecting means so as to offset distortion of the display image caused by curvatures of the windshield. This construction makes it possible to cause the windshield to display a display image free from distortion.

To provide a tire pressure estimating system which is capable of estimating tire pressure based on a signal representing the rotational speed of a vehicle wheel via a small amount of processing by using low-capacity memory, a wheel speed sensor is provided for each wheel of a vehicle. A pulse signal output by the wheel speed sensor is supplied to a signal processor. In the signal processor, the rotational speed of each vehicle wheel is found from the pulse signal. The signal processor adopts a second-order linear prediction model for the rotational speed of the vehicle wheel and vibration of the tire using parameters identified from values of the rotational speed. A resonance frequency is then found from the identified parameters. Finally, the tire pressure is estimated from a linear relationship between the pressure and the resonance frequency.

A communication system for vehicles, which obtains exact communication processing with responders mounted on vehicles running on a road having a plurality of traffic lanes, is disclosed. An expressway has three traffic lanes. A gantry is disposed in a specified position on the expressway. On the gantry are disposed antenna units to counter the traffic lanes respectively. The antenna units are provided with communication areas by means of a pair of antenna elements respectively. The antenna element is composed of a microstrip array antenna disposed with eight pieces of patches laid out in two rows with four pieces in each row. The antenna units controls communication processing to communicate with vehicles adjoining each other. When response signals are sent from a vehicle mounted responder, the vehicle mounted responder is fixed and communication processing for toll collection is performed. As a result, communication processing with responders mounted on vehicles respectively which are running in the respective traffic lanes can exactly be performed.

A non-volatile memory cell having a structure having improved integration and simplified electrode wiring structure. The programmable non-volatile memory cell of the present invention adopts a mono-layer gate scheme to simplify the electrode wiring structure and to eliminate a current leakage problem of an insulating film between electrodes. A side and bottom of a semiconductor region, which is disposed directly below a capacity electrode section with a gate insulating film interposed therebetween that compose a control electrode, are isolated from another semiconductor region and semiconductor substrate by insulating films. Thus, a high programming control voltage which is not limited by a junction yield voltage between the semiconductor regions and semiconductor substrate may be applied. Due to that, an area of the capacity electrode section of a floating electrode may be considerably reduced.
摘要:
A first wave of a glass breaking sound has a sharp peak due to an impact sound and thereafter it attenuates rapidly. The attenuating characteristics of the first wave is measured with an attenuating time or a magnitude of attenuation thereof so that whether or not glass breaking has occurred is determined. Since an original waveform obtained by a microphone includes noise, low frequency components are eliminated by a high pass filter. The characteristics of the first wave of the glass breaking sound is almost stable. Therefore, by detecting the characteristics from the first wave, the glass breaking can be detected without errors. Further, since the glass breaking is detected by attenuation of the first wave, the detection can be carried out quickly.
