  • Patent number: 5938413
    Abstract: A plurality of finger members disposed adjacent each other are moved by a driving mechanism in a reciprocal, sequential manner. Infusion is carried out when the finger members engage an infusion tube in a peristaltic sequence. The finger members contact each other by projections formed integrally on the upper and lower surfaces of the finger members to reduce the contact surface area. A fluid diversion guiding hole is contained in a tube-pressing portion of each finger member. The guide holes of adjacent finger members are aligned to form a continuous channel for discharging leaking infusion fluid. Bevels surround the guiding holes and are inclined toward the center of the hole. Each finger member also includes a rib that is integral with and protrudes upward from the upper surface of the finger member for blocking infusion fluid from the finger members and drive mechanism.

  • Patent number: 5899665
    Abstract: A flow sensor detects drops of infusion fluid that enter the drip chamber of an infusion system and generates a drop-detection signal indicating each drop detected. A setting controller receives the drop-detection signals from the flow sensor and counts the drops detected and then determines the fluid-flow rate of infusion fluid into the drip chamber. The setting controller then sets the infusion pump so that the fluid-flow rate of the infusion pump substantially matches the fluid-flow rate of the drip chamber. A motion sensor detects drip-chamber movement and generates a motion-detection signal indicating the motion state of the drip chamber. A maintaining controller is coupled to receive the motion-detection signal from the motion sensor. The maintaining controller also stores a signal that indicates a stationary drip chamber.

  • Patent number: 5107431
    Abstract: An automotive engine is provided with a fuel control system having a fuel injector for injecting a properly controlled quantity of fuel into cylinders of the automobile engine. The control system is adapted to cause the fuel injector to inject an increased quantity of fuel when an engine control value, relative to which the automotive engine changes its speed of rotation for a decision as to whether the automotive engine is in an acceleration state, is higher than a critical level. The control system also detects the transmission coupled to the automobile engine, and changes, when a temperature of the automotive engine is lower than a preselected temperature, the critical level according to the type of transmission detected.

  • Patent number: 5086667
    Abstract: An intake system for an automobile engine with a manual transmission or an automatic transmission has a throttle valve disposed in an intake passage for distributing air into cylinders of the engine. A supplementary air distributor provided in association with the intake passage supplementarily distributes air into the intake passage between the throttle valve and engine. The supplementary air distributor is controlled by a controller to distribute different amount of supplementary air according to engine operating conditions. The controller is correctively controlled to vary the amount of supplementary air, by the supplementary air distributor according to atmospheric pressure for every distribution, so as to distribute a larger amount of supplementary air do an automobile engine with an automatic transmission than do an automobile engine with a manual transmission at the same atmospheric pressure.

  • Patent number: 5072711
    Abstract: A fuel injection control system is designed to be commonly available to an engine with a manual transmission and an engine with an automatic transmission. The internal combustion engine has a fuel injection device for delivering different amounts of fuel to the engine according to engine operating conditions. The fuel injection control system causes the fuel injection device to make an increase in fuel amount when the engine operates in a specific zone of engine operating conditions defined by engine operating speeds and loads. When the engine operating condition remains in the specific zone, the control system makes the increase in fuel amount with a time delay from a time the engine operating condition changes into the specific zone.

  • Patent number: 4987874
    Abstract: A control system for controlling spark timing of the engine is to control the retarding of the spark timing at the time of accelerating in anticipation. The amount of retarding the spark timing at the time of accelerating is set larger when the torque converter is provided in a driving system of the engine than when no torque converter is provided. A preferred feature is such that the amount of retarding the spark timing at the time of accelerating is set so as to be decreased gradually from its given initial value and that the retarding of the spark timing is suspended when the retarding amount reaches a value smaller than a given reset value. Both the initial value and the reset value are set to be greater when the torque converter is equipped than those when no torque converter is equipped.

  • Patent number: 4916008
    Abstract: A plastic molding comprising a plastic substrate and a decorative film or sheet which has an outermost layer of fluororesins coated at its one surface with a vaporized metal layer, an intermediate layer of ethylene-acrylic acid copolymeric resins laminated on the metal layer, and an innermost layer of backing resins which is adhered to the intermediate layer by an adhesive layer. The decorative film or sheet is molten to be adhered onto the plastic substrate, so that the backing resin layer comes into contact with the plastic base.
