A sensor device includes: a housing; a sensor element embedded in the tip end of the housing, the sensor element having on one side face thereof a magnetically sensitive surface that faces a side of the housing and having a pair of terminal plates extending from a side face that is opposite to the magnetically sensitive surface; and a cord electrically connected to the two terminal plates and extending from a rear part of the housing. The housing is die-molded so as to embed therein a holder formed as a single member from a synthetic resin, the sensor element which is held by the holder in a state in which the two terminal plates are formed so as to have a bent portion bent in a substantially U-shaped form and connected to the sensor element and a flat plate portion extending along a plane intersecting the sensor element and connected to the bent portion, and part of the cord which is electrically connected to the flat plate portion of the two terminal plates.

The present invention provides a magnetic core whose outer surface has been coated without handling brittle ribbon to thereby impart insulating properties and shape retention properties to the magnetic core after annealing heat treatment, and further provides an adhesive resin composition for a magnetic core, which is useful for efficiently producing the above-mentioned magnetic core without using any organic solvent and which per se is stable to heat and elapse of time. By forming a coating film having a certain thickness or more on an outer surface using a composition containing a resin of specific properties, there can be obtained a magnetic core whose outer surface has been coated without handling brittle ribbon to thereby impart insulating properties and shape retention properties to the magnetic core after annealing heat treatment. The adhesive resin composition containing particles of a resin having specific properties is useful for efficiently producing the above-mentioned excellent magnetic core without using any organic solvent, and this composition is stable to heat and elapse of time.

A method and system for managing a construction machine whereby working time for each of different parts of a hydraulic excavator is measured. Measured data is stored in a memory of a controller and then transferred to a base station computer via satellite communication to be stored in a database. At each repair/replacement of a part in each hydraulic excavator, the base station computer calculates, based on the operation data, a replacement time interval of the part on the basis of the working time per section to which the part belongs, and then stores and accumulates it. The base station computer also reads the stored data for each hydraulic excavator, determines, for each part, a replacement rate of the part having a substantially equal replacement time interval, and calculates a target replacement time interval of the part in accordance with the replacement time interval corresponding to a maximum replacement rate.

The method of the invention for producing a Group III nitride compound semiconductor, employing an etchable substrate which is produced from a material other than the Group III nitride compound semiconductor, includes stacking one or more layers of the Group III nitride compound semiconductor on one face of the substrate and etching the other face of the substrate while stacking one or more semiconductor layers or after completion of stacking one or more semiconductor layers, to thereby reduce the thickness of most of the substrate. The apparatus of present invention for producing a semiconductor through vapor phase growth, contains a substrate for vapor-phase-growing the semiconductor; a source-supplying system for supplying a source for vapor phase growth of the semiconductor; and an etchant-supplying system, wherein the source-supplying system and the etchant-supplying system are isolated through placement of the substrate.

The invention is intended to provide a downhill speed control system which employs a method of setting a target vehicle speed in advance, thereby improving controllability when a vehicle runs down a slope, and giving an operator improved operability in setting of the target vehicle speed. Brakes are controlled so that, when the vehicle runs down the slope, an actual vehicle speed is matched with a target speed set by a switch which can set the target speed by selectively or continuously changing plural preset speeds. Also, control constants for PID control are modified depending on settings of a downslope gradient setting switch and a load setting switch. When an acceleration computed from the actual vehicle speed is larger than a target acceleration, the strength of applied brake is increased.

An AlN layer having a surface of a texture structure is formed on a sapphire substrate. Then, a growth suppressing material layer is formed on the AlN layer so that the AlN layer is partially exposed to the outside. Then, group III nitride compound semiconductor layers are grown on the AlN layer and on the growth suppressing material layer by execution of an epitaxial lateral overgrowth method. Thus, a group III nitride compound semiconductor device is produced. An undercoat layer having convex portions each shaped like a truncated hexagonal pyramid is formed on a substrate. Group III nitride compound semiconductor layers having a device function are laminated successively on the undercoat layer.
