  • Patent number: 5000011
    Abstract: An improved engine driven air conditioning apparatus for heating and cooling an enclosed space is disclosed. The apparatus includes a compressor linked to a reversing valve. The reversing valve is further linked to a pair of interior heat exchangers disposed in heat exchanging contact with an enclosed space, and a pair of exterior heat exchangers disposed in air passageways linked to the external environment. The reversing valve controls the direction of flow of fluid in the circuit. In one position, fluid flows from the compressor through the reversing valve to the exterior heat exchanger, to the interior heat exchanger and then back to the compressor to cool the enclosed environment. In a second position, the flow is reversed to heat the enclosed environment. The apparatus also includes an engine to drive the compressor, and a cooling circuit associated with the engine. The cooling circuit includes a pair of radiators radiating the heat from the coolant.

  • Patent number: 4805689
    Abstract: An outdoor unit for a heat pump is usable under very cold weather conditions since the outdoor unit includes an auxiliary heating system which heats a heat exchanger in order to prevent the heat exchanger from forming frost and which also compensates for the decline in heating capacity. Further, the outdoor unit has an air flow preventing arrangement which prevents the flow of air through the heat exchanger when the absorption of the heat from the atmosphere is not efficient. The outdoor unit drives compressors by an internal combustion engine in order to reduce the consumption of electric power and the coolant for the engine is also utilized to provide auxiliary heat to the heat exchanger. The outdoor unit also includes a boiler to compensate for the lack of heating capacity in the engine waste heat. The boiler is operated when the atmospheric temperature is less than the predetermined value.

  • Patent number: 4530339
    Abstract: Supercharger control apparatus for the internal combustion engine of a motor vehicle comprises a control device which has as input signals the demand signal for acceleration (such as a signal based on the amount of throttle valve opening) and an engine rotational speed signal. Based on predetermined ranges of demand signal for acceleration and engine rotational speed and on the input signals, the control device regulates, through an actuator and bypass valve or through an actuator and variable capacity compressor, the amount of supercharging. The supercharge control apparatus allows a non-supercharged state, a maximum supercharged state, or an intermediate supercharged state. In the intermediate supercharged state, the amount of supercharging is in incremental steps to prevent hunting.

  • Patent number: 4360883
    Abstract: Out of nine equal square picture cells forming a picture, only four picture cells surrounding the central picture cell which is to be restored by estimation are utilized. The central picture cell is divided into four equal square sub-cells. The densities of the sub-cells are determined from the mutual relations between the central picture cell and the four surrounding picture cells to determine the density of the central picture cell.

  • Patent number: 4356555
    Abstract: A picture is divided into equal square picture cells, and the picture cells are sampled in such a manner that the sampled picture cells form a checkered pattern. The density of the non-sampled picture cell is outputted as four data by using the four sampled picture cells surrounding the four sides of the non-sampled picture cell.
