A leak current breaker is provided which includes a detector (10) to detect a leakage current from electric lines, a first removing unit (12) to convert the detected leakage current into a voltage and a voltage detector (14) to detect a voltage developed in electric lines A under testing, a second removing unit (16) to remove a harmonic component included in the voltage, a phase contrast detector (20) to detect a phase contrast from a signal waveform having the harmonic component removed, a frequency calculator (21) to calculate a frequency occurring on electric lines A on the basis of the signal waveform of the voltage having the harmonic component removed by the second removing unit (16), a phase angle calculator (22) to calculate a phase angle of the leakage current flowing through the electric lines A on the basis of the phase contrast and frequency, a root-mean-square value calculator (24) to calculate a root-mean-square value of the voltage having the harmonic component removed by the first removing unit (12), a calculator (27) to calculate a leakage current component Igr arising from an earth insulation resistance included in the leakage current flowing through the electric lines A on the basis of the root-mean-square value and phase angle of the leakage current, a judging unit (29) to judge whether the leakage current component Igr calculated by the calculator (27) has exceeded an arbitrary value, and a circuit breaker (30) to break the electric lines A on the basis of the judgment made by the judging unit (29).
摘要:
A moisturizing pad has a heat generating element sandwiched between first and second surface sheets. The heat generating element contains metal powders, salt, water and water retaining materials adapted to generate oxidation heat and thereby to convert the water to moisture vapor as the element is supplied with oxygen through an air-permeable first surface sheet. The salt and water are provided in a form of saline solution having a salt concentration of 18-22% by weight and the heat generating element is impregnated with such a saline solution in a range of 17.5 to 26% by weight of the element.

The periphery of a load circuit (6) is covered with a conductive material (7) which is electrically connected with a grounding line (N) of an electric line (3) to be measured. A leak current detecting system is provided with a connection judging apparatus (5) for judging whether a plug (1) formed on one end side of the electric line (3) is correctly connected to a receptacle, and a leak current detecting apparatus (4) for detecting a leak current (Igr) flowing in the electric line (3) due to insulation resistance to ground.

Without forming a silicide film on a surface of a photodiode PD formation portion and a surface of a drain portion of a reset transistor T1 having an impurity region as a drain connected to an impurity region of the photodiode PD, the silicide film is formed on a surface of a source portion of the reset transistor T1 and a surface of a source/drain portion of other MOS transistors.

A heat conductivity from a heating body to a user's skin is improved to provide satisfactorily warm feeling to the skin of the user. A laminated heating body has a heating body and a cover sheet covering the heating body. The cover sheet defines at least one low temperature portion formed from a material having low heat conductivity and at least one high temperature portion formed from a material having high heat conductivity. The at least one low temperature portion and the at least one high temperature portion are formed separately on a surface of the cover sheet contacting with a user's skin.

A swash plate compressor includes a cylinder block having therein several cylinder bores and a crank chamber. A drive shaft is rotatably supported in the cylinder block. Each of several pistons is slidably disposed within one of the cylinder bores. A swash plate is disposed in the crank chamber and is tiltably secured to the drive shaft. A bearing couples the swash plate to each of the pistons, so that the pistons are driven in a reciprocating motion within the cylinder bores. Several stepped, chamferred portions are formed in succession on an opening edge of each of the cylinder bores. The structure for the swash plate compressor according to this invention reduce or eliminates damage of the outer surface of pistons without increasing the weight of the swash plate compressor.
