摘要： A thermal protector includes a header plate and a metal housing having an open end hermetically welded to an peripheral edge of the header plate. The housing is formed into a generally slender shape so as to be suited for mounting on end turns of a stator winding of a three-phase electric motor. A thermally responsive element includes a shallow curved portion at which the element changes states of curvature with snap action in response to different ambient temperatures. The thermally responsive element has two movable contacts secured to it to be disposed symmetrically about a center of the curved portion so that the movable contacts are engageable with and disengageable from fixed contacts respectively. A push piece is disposed in the housing to exert a pushing force on a normally convex side of the thermally responsive element. The pushing force is adjusted by deforming the outer surface portion of the housing for calibration of the operating temperature. The push piece includes a portion secured to an inner surface of the housing so as to correspond substantially to the deformed outer surface portion of the housing for calibration of the operating temperature.

摘要： A three-phase thermal protector includes a hermetic receptacle composed of an elliptic dome-shaped cover having an opening at one end and a header plate having two terminal pins extending through respective apertures formed in it, and a switch assembly mounted in the receptacle. Two fixed contacts are secured to the respective terminal pins.

The thermally responsive element carries two movable contacts symmetrical about the center line. The calibrating plate has a push projection pushing the thermally responsive element so that the contact pressure is increased when the calibrating plate is deformed with deformation of the cover for the calibration of the operating temperature. The header plate has a protrusion receiving the thermally responsive element at a position away from its supported end toward the center.

摘要： A fuel evaporative emission flow rate detecting system is capable of detecting a small flow rate of the fuel evaporative emission. The system includes an electromagnetic valve (22) in a communication passage (21). The pressure of the fuel evaporative emission in the fuel tank is detected by means of a magnetic flux detector or so forth. A control circuit is responsive to the pressure of the fuel evaporative emission reaching 15 mmHg, for example, while the communication passage (21) is held closed, to open the communication passage (21). On the other hand, the control circuit closes the communication passage when the pressure of the fuel evaporative emission becomes lower than or equal to 8 mmHg. Depending on a period, in which the communication passage (21) is held open, the flow rate of the fuel evaporative emission is calculated.

摘要： A seismosensitive element includes a housing formed from an electrically conductive material and having an inclined face formed on the bottom thereof to gradually rise concentrically outwardly substantially from a center of the inner bottom face, and a header fixed to the housing to close its open end and having through-aperture in which an electrically conductive terminal pin is fixed in an insulated relation. A contact is fixed an end of the terminal pin located inside the housing and has a plurality of feather portions disposed concentrically with the terminal pin, the feather portions having a predetermined elasticity. An inertia ball is enclosed in the housing to be located substantially at the center in the housing in a normal position of the element in a stationary state. The inertia ball rolls when subjected to oscillation, so that the inertia ball slides on the feather portions of the contact except for distal ends of the feather portions such that the inertia ball electrically conducts between the contact and the housing and such that the feather portions are elastically deformed, thereby receiving a force causing the same to be pushed against the bottom of the housing. An acceleration responsive switch includes a receptacle including a housing having a conical face, an inertial ball in the receptacle, and an oscillation damping liquid in the receptacle. The oscillation damping liquid has a viscosity such that the inertial ball terminates rotation when it is subjected to an external oscillation to be rotated.
