  • Patent number: 4471745
    Abstract: An internal combustion engine is provided with an exhaust gas recirculating passage for communicating the intake passage and the exhaust passage thereof. The recirculating passage is provided with a valve for controlling the amount of recirculated exhaust gas. A fundamental air-fuel ratio control value for regulating the air-fuel ratio of the intake gas to a predetermined value is corrected by an operating condition correction value according to the operating condition of the engine. The operating condition correction value is successively changed to an optimal value by comparing the actually obtained air-fuel ratio with a predetermined value. The operating condition correction value for correcting the fundamental air-fuel ratio control value when the exhaust gas recirculation is carried out is changed independently from the same for correcting the fundamental air-fuel ratio correction value when the exhaust gas recirculation is not carried out.

  • Patent number: 4471898
    Abstract: Disclosed is a modular power supply having a case made up of top, bottom and side plates. Each plate has either a male or female portion at the edge which is slidably interconnectable with the edge of an adjacent plate. In addition, male and/or female portions located on the top, bottom and side plates matingly engage with similar female and/or male portions on a handle, output device receptacle, etc. The internal portions of the power supply are divided into three modular components. The first modular component includes a transformer and a primary coil select switch and is connected to the rear portion of the case preventing the case sides from slipping apart from the top and bottom plates. A second modular component is a printed circuit board interconnectable with the first modular component and containing a temperature control circuit and an air pump and motor combination. The second modular component is slidably received into the case.

  • Patent number: 4472688
    Abstract: A voltage switching amplifier circuit has a comparator which, after comparing signal amplitude to a comparison voltage, switches on a high voltage or low voltage amplifier depending upon whether the comparison voltage is exceeded or not. After the predetermined comparison voltage is exceeded, a positive feedback circuit reduces the comparison voltage enabling the high voltage amplifier to continue operation at least until the signal amplitude drops below the reduced comparison voltage. In a preferred embodiment, a time constant circuit maintains the high voltage amplifier in operation for a predetermined period of time during which the signal amplitude has dropped below and remained below the reduced comparison voltage.

  • Patent number: 4464415
    Abstract: A semi-amporphous, photoelectric conversion semiconductor manufacturing method in which substrates are disposed in a reaction chamber having a gas inlet and a gas outlet and a gas mixture containing at least a semiconductor material gas which includes a dangling bond neutralizer and a carrier gas is introduced into the reaction chamber. An electromagnetic field is applied to the gas mixture to ionize it into a gas mixture plasma in the reaction chamber. The plasma is passed to the substrates where the semiconductor material doped with the neutralizer is deposited on each substrate. The semiconductor material deposited on each substrate becomes a semi-amporphous, photoelectric conversion semiconductor by holding the atmospheric pressure in the reaction chamber below 1 atm and maintaining the substrate at a temperature lower than the temperature at which the semiconductor material on the substrate becomes crystallized.

  • Patent number: 4461688
    Abstract: A magnetron sputtering device wherein a plurality of magnetic field sources are employed to enhance uniformity of cathode sputtering. Each of the magnetic field sources is independently capable of establishing a discharge at the cathode if the other magnetic field sources are removed so that portions of a V-shaped erosion pattern produced by a primary discharge are also eroded to thus effect the more uniform cathode sputtering.In one embodiment of the invention, a magnetic field dome of a first polarity is disposed over a second magnetic field dome of the opposite polarity, the domes being disposed over the cathode so that a closed plasma loop is established, the loop including a first sputtering path which extends over the cathode and a second non-sputtering return path which is disposed over the sputtering path and between the first and second magnetic field domes.

  • Patent number: 4457276
    Abstract: Feedback control is carried out to maintain the idling speed of an internal combustion engine at a desired idling speed determined according to the operating conditions of the engine. When the actual idling speed of the engine significantly falls with respect to the desired idling speed for some reason, the amount of the intake air is increased by a large amount, while when the rotational speed falls to a small extent with respect to the desired idling speed, the amount of the intake air is increased little by little.

  • Patent number: 4451142
    Abstract: In a photographic apparatus for printing an original image on a photosensitive material, focusing is conducted at two different points, and the positions of an easel and a lens at the time of the second focusing are calculated according to the lens formula from the travel amounts of the easel and lens between the first and second focusing positions as well as the focal length of the lens. When the focal length of the lens is unknown, focusing is performed at three points, and the positions of the easel and lens at the time of the third focusing are determined with the lens formula. Pulse motors used to move the easel and lens are controlled by a microcomputer, which adds the number of pulses for forward rotation of the pulse motor and subtracts that for backward rotation. The microcomputer counts and stores the number of pulses indicative of the present positions of the easel and lens.
