Provided is a seatback rotating device. The seatback rotating device includes an electric motor and an application mechanism. The electric motor generates a rotational force that is used to rotationally displace a seatback of a vehicle seat. The application mechanism enables application of the rotational force to the seatback. The application mechanism has a configuration that enables the seatback to be self-rotatable with gravity applied to the seatback in response to the rotational force being applied to the seatback.

A vehicle seat device includes a fixed base, a movable base, a paddle, and an air pack. When a side airbag arranged in the seat is deployed, the expanding side airbag presses and pivots the movable base and allows for a deployment of the side airbag. The paddle is configured to change a seat support form when pressed and pivoted by the air pack. The movable base pivots about a first pivot axis relative to the fixed base. The paddle pivots about a second pivot axis relative to the movable base. The first pivot axis and the second pivot axis are arranged at different locations.

The first securing portion is secured to a first position on the retaining member with a first securing portion fastening member. The second securing portion is secured to a second position on the retaining member via a second securing portion fastening member. The second securing portion includes an insertion hole through which the second securing portion fastening member is inserted. The insertion hole is an elongated hole extending in a direction that connects the first securing portion and the second securing portion to each other.

Intake/exhaust valve device and vehicular seat device

A pneumatic pressure control method for a vehicle seat includes: repeatedly detecting an internal pressure of a bladder provided inside the vehicle seat at intervals; correcting the internal pressure of the bladder based on a differential pressure between a detection value and a target value; and lengthening a detection interval to detect the internal pressure depending on a time elapsing from starting of the vehicle.

A control device calculates an estimate of negative intake pressure based on the relationship between the rotation speed of a crankshaft and a throttle opening degree (Step S). Then, the control device sets the estimate PE of the negative intake pressure, which is calculated in Step S, to a greater value as combustion efficiency of CNG used in engine operation becomes higher (Step S). When the corrected estimate PE of the negative intake pressure becomes smaller than or equal to a reference value PTh (Step S: YES), the control device starts a negative pressure recovery procedure (Step S).

Vehicle control device

An image processing apparatus controls display of a plurality of pieces of image data containing both moving image data and still image data, and includes: a moving image/still image determining unit that determines whether or not image data to be displayed is the moving image data or the still image data, when in a continuous display mode that displays the plurality of pieces of image data continuously in a predetermined sequence; and a display control unit that starts display control of the next image in response to finishing of display of all of the moving image data when the image data to be displayed is the moving image data, and starts display control of the next image data in response to finishing of display of the still image data for a predetermined time when the image data to be displayed is the still image data.

A terminal for a solenoid has a weld portion to which an end portion of a lead wire of the solenoid covered with a cover member is welded. The terminal also has a clamp portion for clamping a portion of the lead wire that is located toward a main body of the solenoid from the end portion of the lead wire. Tensile loads on the lead wire of the solenoid are received by the clamped portion of the lead wire and the welded end portion of the lead wire remains free from tensile loads.

An oil level sensing apparatus has a body which defines a volume having an open bottom. A float in the volume supports a permanent magnet and moves within the volume in accordance with the oil level therein. A reed-switch is affected by the magnet supported on the float to detect a low oil level. A temperature sensitive plate closes the open bottom of the volume at low temperatures in order to prevent false readings. Additionally, in order to prevent false readings during transient oil level fluctuations at higher oil temperatures, a spring opposes the opening of the plate such that a restriction is formed in the path for draining oil from the volume. This delays the oil drainage from the chamber and any resulting low oil level signal.

Oil-level sensing apparatus having a time delay function

An electromagnetic proportional flow control valve includes an electromagnetic solenoid having a bobbin with an axial bore and a fixed core in the axial bore. A valve housing defines a first port, a second port and a valve seat fludically positioned between the first and second ports, while a valve is normally in a closing position for closing the valve seat and interrupting fluid communication between the first and second ports. A movable core is fixed to the valve and positioned relative to the electromagnetic solenoid such that the movable core is attracted to the fixed core upon excitation of the electromagnetic solenoid. As a result, the valve may move from the closing position upon excitation of the electromagnetic solenoid to fluidically communicate the first and second ports. An annular diaphragm is positioned between the valve and the electromagnetic solenoid and is sealingly mounted to the movable core so as to form a fluid tight pressure chamber on a side of the diaphragm opposite the valve. A passage in the movable core fluidically communicates the pressure chamber with the second port so that forces acting on the valve due to pressure differences across the valve are cancelled.

Electro-magnetic proportional flow control valve

A solenoid valve comprises a housing including an inlet port for fluid communication with a positive pressure source and an outlet port for fluid communication with a negative pressure source; a passage for fluid communication between the inlet port and the outlet port; and an axially bi-directional solenoid-actuated valve in the housing for opening and closing the passage, including an electromagnetically movable valve member having a sealing area exposed to the negative pressure from the outlet port when the valve means is in the closed position; and a diaphragm defining a back pressure chamber in fluid communication with the passage for offsetting the effect of the negative pressure on the exposed sealing area and reducing the electromagnetic force required to move the valve member.

Solenoid valve

A solenoid valve includes a non-magnetic main body having therein a solenoid coil and core, the core being formed of magnetic material and extending in the coil along the axial direction thereof. A plate member formed of a magnetic material is positioned at one end of the main body along the direction of movement of the core, and is integrally formed with the coil bobbin. A housing member having fluid communication passages therein is positioned adjacent the plate member at a side of the plate member opposite the main body. A valve structure actuatable by the core is positioned between the main body and the housing member for controlling fluid flow in fluid communication passages within the housing member. A yoke member formed of a magnetic material has a U-shaped including arms mechanically secured to the plate member, and has a bent portion mounted to the core.
