Abstract: A motor-operated valve includes a base portion which is provided at one end of a stator, a linear-motion shaft which is screwed into a rotor and which is supported by the base portion such that the linear-motion shaft can be moved linearly and cannot be rotated, and a valve member which is provided in the linear-motion shaft and which opens and closes the valve port. A first contacting portion on the rotor and a second contacting portion on the stator or an intermediate member disposed between the rotor and the stator, the first and the second contacting portions and being provided in each of the intermediate member or the stator and the rotor, and contacting with each other in the rotation axis direction of the rotor are biased by a rotor biasing means such that they are pressed onto each other.

Abstract: A wheel assembly rotational position identifying apparatus includes an acceleration detector, a control section, and a battery. The control section identifies the rotational position of the wheel assembly based on an acceleration detected by the acceleration detector. The control section operates in a control mode that is a selected one of a normal mode and a power saving mode, in which a power consumption associated with identification of the rotational position of the wheel assembly is smaller than that in the normal mode. The control section switches the control mode to the normal mode when an initiation condition is met in accordance with an input from outside. The control section also switches the control mode to the power saving mode when a termination condition is met in the normal mode.

Abstract: A wheel assembly position identifying apparatus includes transmitters, each of which is provided in one of wheel assemblies and includes a transmission section and a control section, and a receiver, which includes a receiving section, a measuring section, and a wheel assembly position identifying section. The wheel assembly position identifying section is configured to detect, more than once, a rotational position of each wheel assembly at which the RSSI has an extreme value, for each position detecting signal received during one rotation of the wheel assembly, and identify the position of the wheel assembly in which the corresponding transmitter is provided based on variation of the rotational position of the wheel assembly at which the RSSI has the extreme value.

Abstract: Provide is a relief valve in which the flexibility of an attaching position is higher than a conventional relief valve. In the relief valve of the present invention, a discharge hole for discharging a fluid is arranged on a side surface of a cylindrical portion which protrudes from an end surface of a head portion in a bolt-type valve body. A direction change member which changes a direction in which the discharge hole is open to an arbitrary direction is provided. In this way, the relief valve is attached to a fluid device, and then with the direction change member, it is possible to direct the fluid discharge direction to a desired direction, and accordingly, the flexibility of the attaching position of the relief valve is enhanced as compared with the conventional relief valve.

Abstract: A cap has a plurality of engaging portions elastically engageable with a wheel for holding a tire. The cap is configured to partly cover the wheel. Each of the plurality of engaging portions has a spring member formed of metal.

Abstract: Each of a plurality of tire air pressure detectors includes an information retention portion that retains one or more pieces of timing information indicating the time at which the tire air pressure detector has rotated to a specific detector angle in a first time band for withholding transmission of a radio wave signal, and a radio wave transmission control portion that transmits one or more of the pieces of timing information retained in the information retention portion to a receiver in a second time band enabling transmission of the radio wave signal. The receiver includes an axle rotation amount reader portion that receives axle rotation amount information generated in each of a plurality of axle rotation detection portions, and a position determination portion that calculates an axle rotation amount at the point in time at which the tire air pressure detectors have rotated to the specific detector angle.

Abstract: In a wheel position detection apparatus, a first controlling section of a transmitter repeatedly transmits a frame including specific identification information at a timing when an angle of the transmitter is at a predetermined angle. A second control unit of a receiver receives the frame transmitted from the transmitter, and identifies which of a plurality of wheels the transmitter that has transmitted the frame is attached to. The receiver changes an allowable range of variability in accordance with a road surface condition indicated by a degree of road surface roughness every time the frame is received, and sets the allowable range of variability wider for a road surface that is rough than for a road surface that is not rough.

Abstract: In an oil pan inner tank valve structure, a disc-shaped float valve is arranged below a valve port that provides fluid communication between the inside and outside of a bottom wall of an inner tank, and a lower cover is arranged below the float valve. In addition, a center recess is depressed at a lower surface center of the float valve, and a lateral movement restricting pin is upright from the lower cover and is constantly engaged with the center recess by recess/protrusion engagement. The lower cover restricts a vertically movable range of the float valve. In addition, the lateral movement restricting pin restricts lateral movement of the float valve so that a top portion of an upper surface bulged portion vertically constantly faces an area inside a valve seat.

Abstract: A flow control valve includes a housing that includes a fluid inlet and a fluid outlet; a valve body that together with the housing, forms a first chamber with a variable volume and a second chamber with a variable volume; a communication passage that connects the first chamber and the second chamber together; and an urging portion that urges the valve body in a direction in which the volume of the first chamber decreases. When the valve body moves in a direction to increase the volume of the first chamber against urging force of the urging portion, the valve body moves closer to the fluid outlet and reduces a degree to which the second chamber is communicated with the fluid outlet.

Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.
