  • Publication number: 20150362089
    Abstract: A flow rate control device includes a needle valve mounted within a body section and is configured such that the needle valve is advanced and retracted within the body section by the rotation of a handle, thereby adjusting the flow rate of fluid flowing between a first port and a second port. The handle is surrounded by a cover to prevent a change in the adjusted flow rate.

  • Patent number: 9189454
    Abstract: A two-wheeled motor vehicle includes a control device and is configured such that a radius of curvature of a cross-section of a tire mounted on one of the front wheel and the rear wheel is larger than a radius of curvature of a cross-section of a tire mounted on the other wheel. The control device includes a sensor arranged to detect a rotation speed of the one wheel, a sensor arranged to detect a rotation speed of the other wheel, and a turn determining section programmed to determine that the vehicle is turning based on a condition that a value corresponding to a bank angle of the vehicle is higher than a threshold. The value corresponding to the bank angle of the vehicle is a value indicating the relative amount of the rotation speed of the one wheel relative to the rotation speed of the other wheel.

  • Patent number: 8437929
    Abstract: A transmission control system includes an ECU, a throttle actuator, a clutch actuator, and a shift actuator. The throttle actuator adjusts a throttle opening under control of the ECU, the clutch actuator adjusts a state of a clutch under control of the ECU, and the shift actuator changes a gear position of a transmission under control of the ECU. When the transmission is shifted down, a throttle opening is adjusted to a first value and the clutch is disconnected such that a rotational speed of an engine increases. Then, the gear position of the transmission is moved to a lower position by one stage with the clutch being disconnected. After that, the throttle opening is decreased to a second value, and connection of the clutch is started. The second value is set to a value larger than a minimum value.

  • Patent number: 8335624
    Abstract: A pressure sensor detects the change in pressure within a cylinder in a clutch master cylinder in a case where a clutch shifts from a connected state to a disconnected state. The pressure within the cylinder is detected at a time point where a rate of the pressure increase is changed. The position of a rod in this case or the rotation angle of a motor in an actuator is detected as a touch point preparation position. The touch point preparation position is a stage preceding power generated by an engine being transmitted to the clutch. The actuator moves the rod at high speed until the position of the rod reaches the position corresponding to the touch point preparation position.

  • Patent number: 6675994
    Abstract: A fluid squirt gun includes a linear flow path provided in a barrel, a nozzle at a tip end of the flow path, a valve seat provided in the flow path, a valve element disposed for movement in an axial direction of the flow path to open and close the valve seat, a spring for pressing the valve element in a valve-closing direction, and a trigger for opening and closing the valve element. The valve element includes a forward pressure receiving face on which fluid in the flow path acts in a valve-opening direction in a closed state of a valve and a reverse pressure receiving face on which the fluid acts in the valve-closing direction in the closed state of the valve and both the pressure receiving faces have substantially equal pressure receiving areas.

  • Patent number: 6208391
    Abstract: An LCD (Liquid Crystal Display) device with a built-in electroluminescent body of the present invention includes a liquid crystal cell having an upper LCD substrate, a lower LCD substrate, and a liquid crystal layer formed between the upper LCD substrate and the lower LCD substrate by the injection of liquid crystal. An upper polarizer and a lower polarizer are respectively positioned on the top and the bottom of the liquid crystal cell. The electroluminescent body is arranged on the lower polarizer in the form of wirings for implementing back illumination. Dust and other impurities are prevented from penetrating the gap between an LCD and an EL (Electroluminescent Lamp) at the time of production. The lower polarizer plays the role of an EL substrate at the same time and thereby eliminates the need for an EL substrate and an affixing material. The LCD device can be produced by a minimum of steps.

  • Patent number: 5675397
    Abstract: Display equipment with exposed electrodes formed for establishing an electric connection with each of liquid crystal display, an electroluminescent light and a printed board. Anisotropic, electrically conductive elastomer pieces are placed between the respective exposed electrodes of the printed board, the liquid crystal display section and the electroluminescent light. A pressing rubber piece is placed on the side of the electroluminescent light which is opposite to its electrode side, and the component parts are received in and held by a holding frame which houses them from above the liquid crystal display section. Bent tip portions are inserted into the printed board and bent to fix the printed board and the holding frame. The electrode section of the electroluminescent light is pressed by the window head jump of the holding frame via the pressing rubber piece and is connected electrically in a stable manner.

  • Patent number: 5653314
    Abstract: A rodless cylinder with a position detector and a brake has a sliding table which is slidably retained on a cylinder tube. A moving member (piston yoke) of the rodless cylinder is secured to the sliding table. A brake unit part is connected to one side of the sliding table, and a sensor part is connected to the other side of the sliding table. A brake plate is disposed to extend through the brake unit part. Both ends of the brake plate are connected to a first and second head covers, respectively, which are provided at both ends of the cylinder tube. A first and second brake shoes are disposed to sandwich the brake plate therebetween. The first brake shoe is subjected to brake spring force. A passage for supplying a pressure fluid is communicated with the other side of the sliding table. Thus, the brake is actuated by allowing the brake spring force, together with a fluid pressure if necessary, to act on the first brake shoe, and the brake is released by the action of a fluid pressure.
