摘要： An integrated value of discharge quantity of a fuel pump is used as a parameter evaluating a pressure loss of a fuel filter. A target discharge quantity is obtained by correcting a fuel quantity required by an engine with a filter pressure loss correction amount corresponding to an integrated value of the discharged quantity. A target rotational speed of the fuel pump is computed based on the target discharge quantity, so that the target rotational speed is corrected in accordance with the pressure loss of the fuel filter. Alternatively, the target rotational speed may be corrected in accordance with a deterioration degree of the fuel pump.

摘要： An apparatus for detecting an abnormality of a fuel transpiration prevention system which includes a canister with an absorbing device and a control valve provided in a passage between a fuel tank and an intake pipe of an internal combustion engine so that a fuel gas generated within the fuel tank is absorbed by the absorbing device of the canister and introduced into the intake pipe by opening and closing the control valve in accordance with an operating state of said internal combustion engine. The apparatus includes a pressure detecting device for detecting a pressure within the fuel tank and a deviation calculating unit responsive to the output of the pressure detecting device for calculating a deviation between the pressure detected when the control valve opens the passage and the pressure detected when the control valve closes the passage. The apparatus decides an abnormality of the fuel gas supply system on the basis of the deviation calculated by the deviation calculating unit. This arrangement allows accurate abnormality detection throughout the fuel transpiration prevention system.

摘要： Five color television cameras take pictures of an object. A video signal from the central camera is transmitted by circuitry substantially the same as the circuitry used in existing color television system. The video signal is subtracted from four video signals from the other cameras, two located on the left side of the central camera and the remaining two on the right side thereof, thus generating four video difference signals. A carrier wave is used of frequency 1/n (n is an integer) of the color sub-carrier frequency, and placed within the lower sideband of the reference frequency of an assigned channel. The spectrum distribution of the wave remains in interleaving relation with the spectrum distribution of a luminance signal from the central camera. The carrier wave is divided into two-phase carrier waves. Each of these carrier waves is divided into a positive halfwave and a negative halfwave. The resultant four halfwaves are amplitude-modulated by the four video difference signals, and the amplitude-modulated halfwaves are superposed one upon another, thus providing a composite wave. The composite wave is band-limited so that it does not exceed the bandwidth of the channel assigned and then transmitted. At the receiving side, five video signals are reproduced. Three electron beams corresponding to the three primary colors, are in synchronism with the five video signals, thereby to reproduce five pictures in stereoscopic relation on the focal plane of a lenticular lens screen.

摘要： A control system controls a multiphase rotating machine by a 120° energization process and a PWM process. In the 120° energization process, respective ones of switching elements of a high side arm and switching elements of a low side arm of a power conversion circuit are turned on. In the PWM process, the switching elements of the power conversion circuit turn on/off so that two phases that are connected to the switching elements that are in the on-state are alternately rendered conductive to the high potential side input terminal and the low potential side input terminal of the power conversion circuit.

摘要： A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section. Intermediately pressurized fuel in a fuel pump is supplied to the jet pumps, so that fuel can be steadily supplied to the jet pumps regardless of fuel consumption amount in an engine. Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.

The motor is a brushless motor and has a stator core, coils and a rotor. An electrical energization for the coils wound around the stator core is controlled in response to a rotating position of the rotor, thereby the rotor is rotated. The rotor has a shaft, a rotating core and a permanent magnet, and the rotor is rotatably mounted at the inner circumference of the stator core. The permanent magnet is mounted at the outer circumference of the rotating core and magnetically energized so as to form magnetic poles different alternatively in a rotating direction at the outer circumferential surface facing the stator core.
