  • Publication number: 20190078511
    Abstract: A control method for an internal combustion engine which includes a variable compression ratio mechanism: controlling the compression ratio by using a control target compression ratio whose a variation amount per unit time is limited to be equal to or smaller than a predetermined variation amount threshold value; and setting a first variation amount threshold value which is the variation amount threshold value of the control target compression ratio per unit time toward a high compression ratio side, to be smaller than a second variation amount threshold value which is the variation amount threshold value of the control target compression ratio per unit time toward a low compression ratio side.

  • Publication number: 20180187594
    Abstract: A variable compression ratio internal combustion engine is equipped with a variable compression ratio mechanism configured to change an engine compression ratio in accordance with a rotational position of a control shaft, and a housing that accommodates therein a drive motor for changing and holding the rotational position of the control shaft. A reference position of the control shaft is learned in a state where a position of maximum rotation of the control shaft in a first rotational direction has been mechanically restricted by bringing a first movable part, which operates in conjunction with the control shaft, into abutted-engagement with a first stopper provided outside of an engine body. Subsequently, a maximum conversion angle range of the control shaft is learned in a state where a position of maximum rotation of the control shaft in a second rotational direction has been mechanically restricted by a second stopper.

  • Patent number: 8348042
    Abstract: An optical sensing device for detecting plural optical features of valuable papers is provided that comprises first and second photocoupers 5 and 6 or 9 and 10 positioned in the vicinity of and on the opposite sides of a passageway 13 for guiding the valuable paper 64. Each of first and second photocouplers 5 and 6 or 9 and 10 has a light emitting element 20, 22, 30, 32 for emitting a light, and a light receiving element 21, 23, 31, 33 for selectively receiving the light from the light emitting element 20 so that each light receiving element 21, 23, 31, 33 can receive lights reflected on and penetrating the valuable paper 64 for detection of multiple optical features from the valuable paper 64.

  • Patent number: 8276734
    Abstract: Centering device 14 of a bill validator comprises a pair of pinch jaws 15 positioned on the opposite sides of a passageway 6, and a centering motor 30 for moving pinch jaws 15 toward and away from each other for reciprocation of pinch jaws 15 so that pinch jaws 15 come into contact with side edges of a bill between pinch jaws 15 to align a central line of bill with a central line of passageway 6. As centering motor 30 stalls when warpage resistance by centered bill is greater than inherent holding torque of centering motor 30, centering device 14 has the simplified structure with reduced number of structural components for light weight and reliable centering operation.

  • Patent number: 6179110
    Abstract: A bill validator is provided which comprises a rotator with a slit and being rotatably attached to the bill validator, the slit being capable of aligning with a passageway when the rotator is in an initial position; a driving device for rotating the rotator; and a validator control circuit for judging authenticity of the bill by outputs of detective sensors and for controlling the driving device. The validator control circuit produces outputs to operate the driving device and thereby to rotate the rotator so as to wind some pulling string connected to the bill around the rotator after the bill passes the slit of the rotator, and the circuit evaluates the rotation rate of the rotator, and detects the unauthorized pulling string.

  • Patent number: 5898427
    Abstract: A pen for providing input to an electronic apparatus includes a cylindrical pen body made of a resin, a pen tip attached to one end of the pen body, and a weight member disposed within the pen body and offset from the axis of the pen body. The weight member is of a density higher than that of the rein. This allows the center of gravity of the pen body to be radially eccentric with respect to the axis thereof and aids in preventing rolling of the pen.

  • Patent number: 5135822
    Abstract: A battery housing structure including a holding portion for holding a battery and a lid for covering the holding portion, the holding portion being arranged on a case of an electronic device, includes a sliding member for slidably moving between a first position and a second position, and a blocking member for preventing the lid from being mounted on the case when the tip of the sliding member is located at the second position. The first position corresponds to a position where a tip of the sliding member comes into contact with the battery when the battery is held on the holding portion, and the second position corresponds to a position where the tip of the sliding member stops when the battery is not held on the holding portion.
