The invention discloses a lithium cell safety valve which comprises a sealing ring, a top cover, a PTC (Positive Temperature Coefficient) ring, an anti-explosion membrane and a pore plate, wherein the top cover, the PTC ring, the anti-explosion membrane and the pore plate are sequentially arranged in the sealing ring from top to bottom; a horizontal clip fastening end of the anti-explosion membrane is clipped and fastened above the periphery of the top cover; and the periphery of the top cover is aligned to the outer edge of the PTC ring. The lithium cell safety valve also comprises insulating layers which are arranged at the inner sides of a vertical clip fastening end and the horizontal clip fastening end of the anti-explosion membrane, at the outer side of the edge on the periphery of the top cover and at the outer side of the edge of the PTC ring and clipped and fastened above the periphery of the top cover. In the lithium cell safety valve, the insulating layers are arranged at the outer side of the edge on the periphery of the top cover, at the outer side of the edge of the PTC ring and between the vertical clip fastening end and the horizontal clip fastening end of the anti-explosion membrane, which can prevent the anti-explosion membrane from causing a short circuit on the PTC ring to invalidate the PTC ring and guarantee that the protection function of the PTC ring isnot influenced, thus the lithium cell safety valve can be used for solving the problem of cell leakage quality and has the advantages of high rigidity and convenient assembly.

#CMT# # / CMT# The switch (S) has a switching mechanism configured to separate switching contacts to open a switch, a measurement transformer arranged at a conductor and configured to generate an analog measurement voltage corresponding to the alternating current. An input of a monoflop (M1,M2,M3) is connected to a pole of a power converter (2a,2b,2c). The transducer voltage of the monoflop is set such that a predetermined period is provided up to reset of the monoflop and that the level at an output of the monoflop is used for checking the function of the power converter. #CMT# : # / CMT# An independent claim is included for a method for testing a power converter of a power supply of a switch. #CMT#USE : # / CMT# Switch, particularly circuit breaker, for low voltage for interrupting an alternating current flowing through a conductor, and distributing the current in electrical switchgear. #CMT#ADVANTAGE : # / CMT# The switch has an input of a monoflop, which is connected to a pole of a power converter , where transducer voltage of the monoflop is set such that a predetermined period is provided up to reset of the monoflop and that the level at an output of the monoflop is used for checking the function of the power converter, and hence protects electrical switchgear, prevents damage of electrical switchgear, and ensures reliable operation of switch. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a circuit diagram of a power supply. 1 : Power supply 2a,2b,2c : Power converter D1,D2,D3 : Diodes M1,M2,M3 : Monoflop S : Switch.

The present invention relates to a protective member and a communication terminal device including the same. The protective member (100) having a plate shape is characterized by including: a first base material (10) that is a chemically strengthened glass; and a second base material (20) formed of a material different from a material forming the first base material (10), in which with respect to values of relative permittivity and dielectric loss tangent at a frequency of 10 GHz of the first base material (10) and the second base material (20), the value of at least either one of the relative permittivity and the dielectric loss tangent of the second base material (20) is smaller than the value of the relative permittivity or the dielectric loss tangent of the first base material (10).

The invention provides an endoscope provided with a built-in element protection means capable of protecting a built-in element and locally regulating a bend to protect it easily as well. A light guide fiber bundle 31 as a thin and long flexible built-in element is inserted in the state of being covered with an exterior tube 32 inside a curved part 6 and inside a flexible tube part 5 on the distal end side in an insertion part, and the outer side is covered with a coil member 34 for protection. Since large external force acts on the light guide fiber bundle 31 arranged at a part where the curved part 6 is largely curved, a hard part 38 is formed by adhering the adjacent strands with each other with an adhesive material 36a at the coil member 34 for the protection covering the part, the bend more than needed is regulated, and the built-in element is protected effectively over a long period of time.
