Abstract: There is provided a very reliable three-way solenoid valve that can reliably switch a refrigerant flow passage while ensuring a refrigerant flow rate even under a large-differential pressure environment without increasing the size of an electromagnetic coil and the like. A valve body includes a conduction hole that communicates with a back pressure chamber formed on a side of a second valve element opposite to a second valve seat, a third valve seat that is positioned between the conduction hole and a second outlet, a third valve element that is movably disposed so as to approach and be separated from the third valve seat, a coil spring that biases the third valve element toward the third valve seat, and actuating rods that are interposed between a first valve element and the third valve element.

Abstract: There is provided a two-stage pilot solenoid valve of which the size is reduced as a whole and which is excellent in mountability. A first valve element, which is slidably fitted to a first valve chest, is movable in a direction different from upward/downward moving directions of a valve stem, which is provided with a second valve element, and a pilot valve element that is driven so as to be opened and closed according to upward/downward movement of the valve stem.

Abstract: A GPS-enabled radar detector capable of storing a database of points of interest is provided. The radar detector comprises a display capable of indicating not only the presence of a point of interest, but also an indication of the direction between the unit and a specified point of interest. In an alternate embodiment, the device comprises a display capable of displaying multiple, simultaneous alerts.

Abstract: A pressure control valve, which has a main valve for control, capable of opening and closing a valve hole by means of a diaphragm, and controls the pressure of a fluid by the agency of the main valve for control, comprises a non-return auxiliary valve located around the main valve for control so as to be coaxial therewith. The non-return auxiliary valve includes a cylindrical portion to be guided by a valve guard body having the valve hole therein and an annular rib extending outward from one end of the cylindrical portion. The rib can engage an auxiliary-valve seat on an outlet-side case.

Abstract: In a control valve for a variable capacity compressor, a patch member is provided to a movable-side end portion of a bellows main body. A valve rod is fitted in the fitting recessed portion formed in the patch member. A compression coil spring is disposed between the patch member and a lower patch member for supporting a fixed-side end portion of the bellows main body.

Abstract: A method and apparatus for detecting a radar signal is disclosed. The method includes counting pulses emanating from an engine of a motor vehicle. An operating mode is determined in response to a moving average of pulses counted. An alarm signal is transmitted in response to detection of a radar signal and the operating mode.

Abstract: An emergency lock retractor equipped with a webbing clamp device includes means for holding lock means such as an arm out of engagement with a take-up reel while detection means detects that the associated webbing is not worn by the occupant. The above emergency lock retractor can provide a highly-reliable seat belt system free of the end locking problem, because its emergency lock mechanism is kept inoperative while no emergency locking is required.

Abstract: Disclosed is a method of manufacturing an electromagnetic member having properties of magnetic anisotropy as well as electrical conductivity, comprising the steps of coating an outer circumferential surface of each of a plurality of magnetic strips with a first electrically conductive material to a predetermined thickness to thereby form a plurality of composite magnetic strips, binding the plurality of composite magnetic strips, and filling spaces among the plurality of composite magnetic strips in the bundle with a second electrically conductive material substantially the same as the first electrically conductive material. By this method, a mechanically strong electromagnetic member can be obtained in which adjusting the thickness of the first electrically conductive material, the ratio between the magnetic property and the electrically conductive property can be easily adjusted by adjusting the thickness of the first electrically conductive material and blow-holes can be prevented from being generated.
