Abstract:
A new type of engine, which incorporates rotors each equipped with a plurality of vanes and has a volume of a portion necessary for constant pressure heating expansion turned into a volume of an air motor side, is composed by functionally combining vane rotary air compressors and vane rotary air motors. More particularly, there is an engine conception mainly intended for vehicles of solving, without reducing the engine efficiency, problems concerning complete combustion and prevention of nitric oxide production, which have been generally considered it difficult to realize by reciprocating engines.
Abstract:
A pressure device applies pressure to a sheet medium on part of a surface of which an image bearer is formed. The pressure device includes: a driving unit that changes a distance between a first pressing unit and a second pressing unit; a control unit that controls the driving unit such that the distance between the first pressing unit and the second pressing unit becomes a set target value; and a target setting unit that sets the target value to a first distance that is larger than a thickness of the sheet medium when the sheet medium is not present between the first pressing unit and the second pressing unit, and sets the target value to a second distance for applying a target pressure to the sheet medium when the sheet medium and the image bearer are present between the first pressing unit and the second pressing unit.
Abstract:
A pressurizing device includes: first and second rollers that holds a sheet-like medium with an image bearer formed on at least part of a surface of thereof between the first and second rollers and send the medium in a conveying direction while applying a pressure to the medium; a position control unit that performs feedback control of the position of at least one of the first and second rollers; a force control unit that performs feedback control of a force acting on between the first and second rollers; and a control-method switching unit that switches, after the position of the first and second rollers is switched from a separation position to a contact position by the feedback control performed by the position control unit, a feedback controlled object so that the force becomes a target value of nip pressure through the feedback control performed by the force control unit.
